Abstract

A method and an electronic apparatus for drying out walls are described. The apparatus comprises an LC oscillating circuit, in which natural oscillations are excited by square-wave pulses of a pulse train signal. The pulse repetition frequency of the excitation signal is lower than the natural frequency of the resonator. After each oscillation excitation by the pulse train signal, the resonator performs a damped oscillation, the amplitude of which drops during the course of half a period of the pulse train signal to a value less than 10% of the maximum amplitude of the oscillation, the resonator emitting in time with the pulse train signal successive electromagnetic wave trains of an amplitude decreasing in a manner corresponding to the oscillation variation of the resonator.

Description

Postopek odpravljanja vlage iz zidu in elektronski aparat z izvedbo postopkaMoisture Removal Procedure and Electronic Appliance by Performing the Process

Izum se nanaša na postopek odpravljanja vlage iz zidu, pri katerem zid izpostavimo elektromagnetnemu sevanju, izvajanemu s pomočjo elektromagnetnega resonatorja, pri čemer to sevanje odseva odsevalna naprava in pri čemer resonator za izvajanje elektromagnetnega sevanja vzbujamo s periodičnimi električnimi impulzi s frekvenco zaporedja impulzov, ki je manjša od frekvence lastnega nihanja resonatorja, v elektromagnetne lastne nihaje.The invention relates to a method of removing moisture from a wall, in which the wall is exposed to electromagnetic radiation carried out by means of an electromagnetic resonator, wherein the radiation is reflected by a reflecting device and the resonator for electromagnetic radiation is excited by periodic electrical impulses with a frequency of pulse sequence, which is less than the resonator self-oscillation frequency, into electromagnetic self-oscillations.

Izum nadalje zadeva elektronski aparat za odpravljanje vlage iz zidu, z elektromagnetnimi resonatorjem, zlasti L-C-nihajnim krogom, z vezjem dajalca impulzov, ki je povezano z resonatorjem in ki za vzbujanje lastnih nihanj resonatorja oddaja periodične impulze s strmima bokoma impulza in s frekvenco zaporedja impulzov, ki je manjša od frekvence lastnega nihanja resonatorja, in z napravo za sevalno oddajanje elektromagnetnih valov, kijih generira nihanje resonatorja.The invention further relates to an electronic apparatus for removing moisture from the wall, with an electromagnetic resonator, in particular an LC oscillator circuit, with an impulse encoder connected to the resonator, which emits periodic pulses to excite the oscillations of the resonator with steep pulse flanks and a pulse sequence frequency , which is less than the frequency of the resonator's own oscillation, and with a device for radiating electromagnetic waves that generates resonator oscillation.

Področje uporabe izuma je odpravljanje vlage iz zidu, katerega vlaga zlasti preko vzpenjajoče se mokrote, do kakršne prihaja npr. zaradi kapilarnih, osmotski ali drugi elektrokinetični učinki, povzroča vdiranje talnice, zadržujoče se vode ali kondenčne vode v zid, po katerem se ta voda nato vzpenja.The scope of the invention is the removal of moisture from the wall, which is moistened especially by the rising wetness, e.g. due to capillary, osmotic or other electrokinetic effects, it causes the melting of the smelter, the retaining water or the condensate water into the wall, after which this water then rises.

Znano je, da imajo električna oz. elektromagnetna polja vpliv na vzpenjajočo se vlago v zidovih in da se jih da s pridom uporabiti za odpravljanje vlage iz zidov.They are known to have electrical or electromagnetic fields affect the rising moisture in the walls and can be conveniently used to remove moisture from the walls.

Na osnovi boja proti vlagi z električnimi polji delujejo takoimenovani elektroosmotski postopki. Pri teh postopkih se električno polje vzpostavi s pomočjo v zid in zemljo vloženih elektrod.The so-called electro-osmotic procedures work on the basis of the humidity control of the electric fields. In these procedures, an electric field is established by means of electrodes inserted into the wall and earth.

Za pravilno opredelitev položaja in pritrditev elektrod pa so poleg drugega potrebni znatni gradbeniški posegi v zid.Nadaljnja pomanjkljivost znanih elektroosmotskih postopkov je v tem, da elektrode tekom časa oksidirajo oz. korodirajo in imajo potemtakem le omejeno obratovalno dobo.In addition, considerable construction work on the wall is required for the correct determination of the position and attachment of the electrodes. A further disadvantage of known electro-osmotic procedures is that the electrodes oxidize over time. they therefore corrode and therefore have only a limited service life.

Presenetljivo se je pokazalo, da se da vlago iz zidu odpraviti tudi brez v zid vloženih elektrod, če na vlažni zidvplivamo z elektromagnetnim sevanjem. Po tem principu delujoči elektronski aparat uvodoma omenjene vrste je znan iz avstrijske patentne prijave 2398/86. Znani aparat obsega L-C-nihajni krog, ki se vzbuja z vezjem dajalca impulzov v resonančna nihanja. Frekvenca lastnega nihanja oz. resonančna frekvenca nihajnega kroga znaša mnokratnik frekvence zaporedja impulzov impulznega dajalca. Frekvenca zaporedja impulzov impulznega dajalca je prilagojena fluktuacijski frekvenci elektromagnetnega zemeljskega polja in leži pri 7 do 15 impulzih na sekundo. S posebnimi veznimi ukrepi se resonančno nihanje nihajnega kroga ohranja med vsakim nihanje vzbujajočim impulzom za določeno dobo z nespremenljivo močjo. Antena, ki je preko sprežnega kondenzatorja priključena na nihajni krog, odseva v nihajnem krogu generirane nize elektromagnetnih valov z v bistvu nespremenljivo amplitudo pri posameznem nizu valov v taktu impulzov, ki vzbujajo nihanje.Surprisingly, it was shown that moisture can be removed from the wall without electrodes inserted into the wall if electromagnetic radiation is applied to the wet wall. According to this principle, a functioning electronic apparatus of the above mentioned type is known from Austrian patent application 2398/86. The known apparatus comprises an L-C oscillation circuit, which is excited by the impulse transducer circuit in resonant oscillations. Frequency of self-oscillation or the resonant frequency of the oscillating circuit is the multiple of the impulse encoder sequence frequency. The pulse sequence of the pulse encoder is adjusted to the fluctuating frequency of the electromagnetic ground field and lies at 7 to 15 pulses per second. With special coupling measures, the resonant oscillation of the oscillation circuit is maintained during each oscillating excitation pulse for a fixed period of constant power. The antenna, which is connected to the oscillating circuit via a coupling capacitor, reflects in the oscillating circuit the generated series of electromagnetic waves with essentially unchanged amplitude at each set of waves in the pulse cycle that induces oscillation.

Znani elektronski aparat terja sorazmerno veliko zamotanost v konstrukcijskem pogledu vezja za izvajanje z vidika frekvence na elektromagnetno zemeljsko polje naslonjeni signal zaporedja impulzov, za ohranjanje v bistvu konstantne amplitude resonančnega nihanja nihajnega kroga in za časovno omejevanje nihajnih nizov znotraj periode signala vzbujevalnega impulza.The known electronic apparatus requires a relatively large amount of complexity in the circuit design to perform, from a frequency perspective, an impulse sequence-based signal, to maintain a substantially constant amplitude of the resonant oscillation of the oscillating circuit, and to limit the oscillating arrays within a period of the excitation pulse signal.

Izum je osnovan na nalogi, podati z enostavnimi sredstvi izvedljiv učinkovit neporušni postopek za odpravljanje vlage z zidov.The invention is based on the task of providing, by simple means, a viable, non-destructive process for removing moisture from walls.

Za rešitev te naloge se po izumu predlaga, da za ustvarjanje elektromagnetnega sevanja uporabimo resonator, ki po vsakem vzbujanju s signalom zaporedja impulzov izvaja dušeno nihanje, katerega amplituda med trajanjem polovice periode signala zaporedja impulzov pade na vrednost manj kot 10 % maksimalne amplitude nihanja.In order to accomplish this task, it is proposed according to the invention to create a electromagnetic radiation using a resonator which performs a damped oscillation after each excitation with a pulse sequence signal whose amplitude drops to a value of less than 10% of the maximum oscillation amplitude during the half period of the pulse sequence signal.

Presenetljivo se je pokazalo, da posebno dobro odpravljanje vlage z zidu, ki ga je treba obdelati, dosežemo tedaj, če je resonator dušen tako, da njegova nihajna amplituda znotraj četrtinske periode signala impulznega zaporedja pade na vrednost manj kot 10 % maksimalne amplitude.Surprisingly, it has been shown that a particularly good elimination of moisture from the wall to be treated is achieved if the resonator is damped so that its oscillatory amplitude drops to a value less than 10% of the maximum amplitude within the quarterly period of the impulse sequence signal.

Posebno dober učinek odpravljanja vlage se doseže, če uporabimo resonator, katerega frekvenca lastnega nihanja leži v območju 141 kHz ± 4 kHz.A particularly good humidity elimination effect is achieved by using a resonator whose self-oscillation frequency lies in the range 141 kHz ± 4 kHz.

Cilj izuma je nadalje, podati elektronski aparat uvodoma omenjene vrste, za izvedbo postopka, katerega se bo dalo stroškovno ugodno izdelati in ki bo terjal le skromno konstrukcijsko zamotanost v pogledu vezja.The object of the invention is further to provide an electronic apparatus of the aforementioned type for carrying out a process which will be cost-effective to manufacture and which will require only modest structural complexity in terms of the circuit.

Za dosego tega cilja se predlaga, daje resonator zasnovan tako, da po vsakem nihajnem vzbujanju s signalom impulznega zaporedja izvaja dušeno nihanje, katerega amplituda je med trajanjem polovice periode signala impulznega zaporedja zmanjšana na vrednost manj kot 10 % maksimalne amplitude nihanja.To achieve this, it is suggested that the resonator is designed to perform a damped oscillation after each oscillatory excitation, whose amplitude is reduced to less than 10% of the maximum oscillation amplitude during the half-life of the pulse sequence signal.

Resonator tako sodeluje z vezjem dajalca impulzov, da pri pojavu strmega boka impulza doživi elektromagnetni nihajni odklon, kateremu sledijo nadaljnje nihajne periode. Na osnovi dušenja resonatorja izzveni resonančno nihanje med trajanjem polperiode signala impulznega zaporedja domala povsem.S pojavom naslednjega strmega boka signala impulznega zaporedja se operacija nihanja ponovi. Resonator izvaja v taktu signala impulznega zaporedja dušene nize nihanj in pri tem izvaja elektromagnetne valove ustrezno poteku nihanja. Za realizacijo aparata po izumu so potrebni samo maloštevilni ceneni električni oz. elektronski sestavni deli. Kot vezje dajalca impulza se da uporabiti enostavno vezje za formiranje impulzov, kot je npr. SchmittTrigger-vezje ali siceršnje po sebi znano enostavno Trigger-vezja, ki npr. sinusno napetost pretvori v pravokotniško napetost. Signal, ki je doveden enoti za formiranje impulzov, se da odvajati npr. neposredno iz 50 kHz- mrežnega signala, pri čemer ima tedaj signal impulznega zaporedja za vzbujanje nihanja resonatorja frekvenco okoli 50 kHz. Resonator je smotrno zasnovan kot enostaven L-C-paralelni nihajni krog, katerega kakovostni faktor je izbran tako, da se dobi zahtevano dušilno obnašanje resonatorjevega nihanja. Resonator pa je lahko zasnovan tudi kot L-C-serijski nihajni krog.The resonator thus cooperates with the impulse transducer circuit to experience an electromagnetic oscillatory deflection when a steep pulse edge occurs, followed by further oscillation periods. Based on the resonator damping, the resonant oscillation oscillates during the duration of the half-period of the impulse sequence signal almost completely. With the appearance of the next steep edge of the impulse sequence signal, the oscillation operation is repeated. The resonator performs in the pulse sequence of the impulse sequence of the damped series of oscillations, and in doing so conducts electromagnetic waves in accordance with the course of oscillation. In order to realize the apparatus according to the invention, only a small number of low-cost electric or electric appliances are required. electronic components. A simple pulse-forming circuit, such as a pulse generator, can be used as a pulse-generator circuit. SchmittTrigger circuits, or otherwise simply known Trigger circuits, e.g. converts sinusoidal voltage into rectangular voltage. The signal delivered to the impulse generating unit can be transmitted e.g. directly from the 50 kHz network signal, wherein the impulse sequence signal for resonator oscillation is then frequency of about 50 kHz. The resonator is reasonably designed as a simple L-C-parallel oscillation circuit whose quality factor is selected to obtain the required damping behavior of the resonator oscillation. The resonator can also be designed as an L-C series oscillator circuit.

Presenetljivo se je pokazalo, da iz aparata po izumu izhaja posebno dober učinek odpravljanja vlage za osuševanje zidov tedaj, če je resonator tako dušen, da njegova nihajna amplituda v območju četrtinke periode signala impulznega dajalca pade domala povsem, najmanj pa na vrednost manj kot 10 % maksimalne amplitude.Surprisingly, it has been shown that a particularly good effect of eliminating moisture for drying walls is obtained from the apparatus according to the invention if the resonator is so damp that its oscillatory amplitude falls almost completely within the quarter of the pulse donor signal period, at least to a value less than 10%. maximum amplitudes.

V posebno prednostni nadaljnji zasnovi izuma je vezje impulznega dajalca zasnovano kot vezje za oblikovanje impulzov. Vezje za oblikovanje impulzov je priključeno na sekundarno navitje omrežnega transformatorja in transformiran iz omrežja pošiljani signal izmenične napetosti v 50 Hz-pravokotniški signal, katerega uporabimo kot signal impulznega zaporedja za nihajno vzbujanje resonatorja.In a particularly preferred further embodiment of the invention, the pulse donor circuit is designed as a pulse-forming circuit. The impulse design circuit is connected to the secondary coil of the network transformer and transformed from the network a transmitted AC signal into a 50 Hz rectangular signal, which is used as a pulse sequence signal for the oscillatory excitation of the resonator.

Spreženje resonatorja z vezjem enote za formiranje impulzov je prednostno tako izbrano, da tako vzpenjajoči se kot tudi padajoči boki impulzov signala impulznega zaporedja vodijo k vzbujanju nihanja resonatorja. Na ta način se vsaka polperioda pravokotniškega signala izkoristi za ustvarjanje niza nihajev in s tem za emitiranje elektromagnetnega niza valov.Coupling the resonator with the pulse forming unit circuit is preferably so selected that both the rising and falling pulses of the pulse sequence signal pulse lead to the excitation of the resonator oscillation. In this way, each half-wave of a rectangular signal is used to create a series of oscillations and thus to emit an electromagnetic wave set.

Zlasti učinkovito deluje aparat po izumu z vezjem za dušenje pozitivnih napetosti. To dušenje obsega diodo, ki zagotavlja, da nihanja vzbujajoči signal impulznega zaporedja v primerjavi z Zemljinim potencialom ne zavzame nikakršne pozitivne napetosti.In particular, the apparatus according to the invention works effectively with a circuit for damping positive voltages. This damping comprises a diode, which ensures that the oscillating excitation signal of the impulse sequence, compared to the Earth's potential, does not cause any positive voltage.

Poskusi so pokazali, da imamo opraviti s posebno učinkovitim odpravljanjem vlage z zidov z aparatom pop izumu tedaj, če frekvenca lastnega nihanja resonatorja leži v območju 130 do 150 kHz, smotrno 137 do 145 kHz, najbolje pri 141 kHz. Po nadaljnji zasnovi izuma je predviden optični kontrolni kazalnik za za kontroliranje funkcioniranja. Optični kontrolni kazalnik obsega v eni od izvedb dve med vezjem impulznega dajalnika in resonatorjem vzpo.redno vezani, z nasprotnima poloma postavljeni svetlobni diodi. Svetlobni diodi dajeta kontrolo signala impulznega zaporedja.Experiments have shown that we have to deal with particularly effective removal of moisture from the walls of a pop-up apparatus when the resonator oscillation frequency is in the range 130 to 150 kHz, preferably 137 to 145 kHz, preferably at 141 kHz. Following the further design of the invention, an optical control indicator is provided for controlling the operation. The optical control indicator comprises, in one embodiment, two light-emitting diodes arranged parallel to the pole opposite the pole of the pulse encoder and the resonator. The LEDs give impulse sequence signal control.

Za zaščito aparata pred umazanijo in poškodbami je smotrno predvideno ohišje iz umetne snovi.To protect the appliance from dirt and damage, a plastic housing is advisable.

Za nastavitev želene resonatorjeve frekvence so lahko predvidena sredstva za nastavljanje. V primeru L-C-nihajnega kroga se da za justiranje frekvence nastaviti Trimmer-kondenzator ali napravo, ki spreminja induktivnost tuljave.Adjustment means may be provided to adjust the desired resonator frequency. In the case of an L-C swing circuit, a Trimmer capacitor or device that changes the coil inductance can be adjusted to adjust the frequency.

Za sevalno oddajanje elektromagnetnih valov je lahko predvidena antena.An antenna may be provided for radiating electromagnetic waves.

V prednostni varianti pa se kar resonator sam uporabi za emitiranje sevanja. Pri L-Cnihajnem krogu služi kot oddajnik predvsem tuljava. S tem se doseže še nadaljnja poenostavitev vezja.In a preferred embodiment, the resonator itself is used to emit radiation. In the L-Circuit, the coil is primarily the transmitter. This further simplifies the circuit.

V nadaljnjem opisujemo elektronski aparat po izumu na osnovi priloženih skic, v katerih kaže sl. 1 vezje aparata po izumu za odpravljanje vlage iz zidov, delno shematsko, sl. 2 pa diagram poteka signala za pojasnjevanje nihajnega obnašanja resonatorja glede na vzbujevalne impulze vezja impulznega dajalcaThe electronic apparatus of the invention will now be described on the basis of the accompanying drawings, in which FIG. 1 shows a circuit of an apparatus according to the invention for removing moisture from walls, partially schematically; 2 is a flow chart for explaining the oscillatory behavior of a resonator with respect to the excitation pulses of the pulse encoder circuit

Aparat po izumu obsega L-C-vzporedni nihajni krog 10, katerega resonančna frekvenca leži pri 141 kHz. Za justiranje resonančne frekvence je kapaciteta kondenzatorja C nihajnega kroga 10 spremenljiva. Nihajni krog 10 je priključen za vezjem 12 za formiranje impulzov, ki sinusni 50 Hz-signal, katerega pošilja omrežni transformator 14, pretvarja v 50 Hz-pravokotniški signal s ključnim razmerjem 50 % in ta pravokotniški signal dovaja v nihajni krog 10. Med vezjem 12 za formiranje impulzov in nihajnim krogom 10 je vložen optični kontrolni kazalnik 16 z vzporedno vezanima, po njuni pretočni smeri medsebojno nasprotno razporejenima svetlobnima diodama. Kontrolni kazalnik 16 služi za nadzor funkcioniranja aparata.The apparatus of the invention comprises an L-C parallel oscillation circuit 10 whose resonance frequency is at 141 kHz. To adjust the resonant frequency, the capacitance C of the oscillating circuit 10 is variable. The oscillation circuit 10 is connected behind a pulse-forming circuit 12 that converts a 50 Hz sine wave signal transmitted by the network transformer 14 into a 50 Hz rectangular signal with a key ratio of 50% and delivers that rectangular signal to the oscillating circuit 10. During circuit 12 for the formation of pulses and the oscillating circuit 10, an optical control indicator 16 with parallel coupled, in opposite direction to the light emitting diodes, is introduced in their flow direction. The control indicator 16 is used to monitor the functioning of the apparatus.

Omrežni transformator 14 služi tako kot signalni dajalnik za vezje 12 za formiranje impulzov kot tudi kot 12 voltni vir izmenične napetosti za oskrbovanje celotnega aparata po izumu. Upor R skrbi za tokovno omejevanje aparata. Delovni tok znaša le nekaj mA. Aparat potemtakem zahteva le nizko električno moč, kar je povezano s prednostjo nizkih obratovalnih stroškov.The mains transformer 14 serves both as a signal encoder for the pulse-forming circuit 12 and as a 12-volt AC power source for supplying the entire apparatus of the invention. Resistor R takes care of the current limitation of the appliance. The working current is only a few mA. The apparatus therefore requires only low electrical power, which is related to the advantage of low operating costs.

Dioda D je vključena v vezje tako, da proti Zemljinemu potencialu duši pozitivno napetost v aparatu, tako da pravokotniški signal, katerega dobavlja sklop 12 za formiranje impulzov, proti Zemljinemu potencialu ne zavzame nikakršne pozitivne napetosti.Diode D is integrated into the circuit in such a way that it suppresses the positive voltage in the apparatus against the Earth's potential, so that the rectangular signal supplied by the impulse-forming circuit 12 does not take any positive voltage against the Earth's potential.

Funkcioniranje aparata po izumu bomo v nadaljnjem obrazložili na osnovi sl. 2. SL 2 kaže v kvalitativni predstavitvi potek amplitude resonatorjevega nihanja (diagram A) v primerjavi z impulzno sledilnim signalom (diagram B) katerega daje sklop 12 za formiranje impulzov. Frekvenca resonatorja 10 (141 kH) oz. trajanje periode resonatorja iz razlogov poenostavitve risanja nista narisana v merilu.The functioning of the apparatus according to the invention will be further explained on the basis of FIG. 2. SL 2 shows in qualitative presentation the course of the amplitude of the resonator oscillation (diagram A) compared to the pulse-tracking signal (diagram B) given by the circuit 12 for the formation of pulses. Frequency of resonator 10 (141 kH) or. the duration of the resonator period is not plotted on a scale for reasons of drawing simplicity.

Pri pojavu pozitivnega boka F+ pravokotniškega impulzno sledilnega signala se nihajni krog 10 vzbudi v lastno nihanje, ki pa je toliko dušeno, da njegova amplituda A, s čimer je mišljena velikost maksimalnega odklona na posamezno periodo nihanja, med trajanjem četrtinske periode T/4 pravokotniškega impulzno sledilnega signala skorajda popolno izzveni. Naslednji nihajni odklon oz. vzbuditev resonatorja 10 sledi pri pojavu temu sledečega negativnega boka F impulzno sledilnega signala. Spremembe napetosti niza nihanj, ki sledi negativnemu boku F, so usmerjene nasproti tistim iz predhodnega niza nihanj. Nizi nihanj imajo v bistvu enako dušilno obnašanje. Po poteku periode T pravokotniškega impulzno sledilnega signala se zgoraj opisane nihajne operacije ponovijo s pojavom naslednjega pozitivnega boka F .When the positive side F + of the rectangular pulse-tracking signal occurs, the oscillating circuit 10 is excited by its own oscillation, which is so damped that its amplitude A, which means the magnitude of the maximum deviation per individual oscillation period, during the duration of the quarter period T / 4 of the rectangular the pulse of the tracking signal almost completely escapes. The following oscillation deviation or. the excitation of the resonator 10 is followed by the appearance of the next negative side F of the pulse tracking signal. Changes in the voltage of the set of oscillations following the negative side F are directed opposite to those of the previous set of oscillations. The oscillation series have essentially the same damping behavior. After the period T of the rectangular pulse-tracking signal expires, the oscillation operations described above are repeated with the appearance of the next positive side F.

Nihajni krog 10 oddaja nize valov s amplitudnim potekom po diagramu A in v taktu impulzno sledilnega signala, to je v vsaki polperiodi impulzno sledilnega signala en niz valov na okolico.The oscillating circuit 10 emits sets of waves with amplitude paths according to diagram A and in pulse-tracking signal, that is, in each half-period of the pulse-tracking signal, one set of waves per surroundings.

Aparat po izumu ima prednostno ohišje iz umetne snovi, ki elektromagnetnega sevanja, katerega oddaja resonator, ne absorbira ali pa ga absorbira zanemarljivo. Pri aparatu s kovinskim ohišjem je treba poskrbeti za to, da elementi, ki oddajajo sevanja, zlasti tuljava L, ni so obdani z ohišjem. Ni nujno, da je impulzno sledilni signal pravokotniški signal. Pomembno pa je, da impulzno sledilni signal zajema resonančno frekvenco resonatorja kot spektralno komponento, kar je med drugim slučaj, če imajo impulzi strme boke impulzov.The apparatus of the invention preferably has a plastic housing that does not absorb or absorb electromagnetic radiation emitted by the resonator or negligibly. For apparatus with a metal housing, care must be taken to ensure that the elements emitting radiation, in particular the coil L, are not surrounded by the housing. The impulse tracking signal does not have to be a rectangular signal. It is important, however, that the pulse-tracking signal captures the resonant frequency of the resonator as a spectral component, which is, inter alia, if the pulses have steep pulse flanks.

Aparat po izumu smotrno postavimo v bližino zidu, s katerega je treba odpraviti vlago. Doseg, ki je bil dosežen v poskusih z zgoraj opisanim izvedbenim primerom v okviru katerega smo lahko ugotovili še dobro odstranitev vlage, leži pri okoli 20 m pri čemer smo merili časovno razporejeno moč oddajnika okoli 15 μ\\'.The apparatus according to the invention is conveniently placed close to the wall from which moisture must be removed. The range achieved in the experiments with the embodiment described above, in which good moisture removal could be found, lies at about 20 m while measuring the transmitted power of the transmitter at about 15 μ \\ '.
