Description

  

  Kleinsender für drahtlose     Telegraphie.     
EMI0001.0002     
  
    Die <SEP> Forderung <SEP> nach <SEP> kleinen, <SEP> sehr <SEP> leichten
<tb>  Funktelegraphiesendern <SEP> wurde <SEP> bis <SEP> beute <SEP> da  durch <SEP> erschwert, <SEP> dass <SEP> die <SEP> Anodenbatterie <SEP> ein
<tb>  zwei- <SEP> oder <SEP> dreifaches <SEP> Gewicht <SEP> den <SEP> übrigen
<tb>  Teilen <SEP> des <SEP> Kleinsenders <SEP> gegenüber <SEP> aufwies.
<tb>  Dieser <SEP> Nachteil <SEP> wird <SEP> durch <SEP> die <SEP> vorliegende
<tb>  Erfindung, <SEP> von <SEP> der <SEP> in <SEP> den <SEP> Fig.

   <SEP> 1 <SEP> und <SEP> 2 <SEP> ein
<tb>  Ausführungsbeispiel <SEP> dargestellt <SEP> ist, <SEP> behoben.
<tb>  Statt <SEP> der <SEP> schweren <SEP> Anodenbatterie <SEP> ist <SEP> parallel
<tb>  zum <SEP> Heizkreis <SEP> (Batterie <SEP> F) <SEP> ein <SEP> Sucnmer <SEP> (E)
<tb>  geschaltet, <SEP> der <SEP> die <SEP> Stromstösse <SEP> der <SEP> Primär  wicklung <SEP> eines <SEP> Transformators <SEP> (C) <SEP> zuführt.
<tb>  Hier <SEP> wird <SEP> nun <SEP> die <SEP> Spannung <SEP> hinauftrans  formiert <SEP> und <SEP> der <SEP> Röhre <SEP> (A) <SEP> zugeführt.

   <SEP> Die
<tb>  übrige <SEP> Schaltung <SEP> ist <SEP> die <SEP> normale <SEP> Dreipunkt-     
EMI0001.0003     
  
    schalteng, <SEP> wobei <SEP> die <SEP> Rückkopplung <SEP> auf <SEP> das
<tb>  Gitter <SEP> der <SEP> Röhre <SEP> über <SEP> den <SEP> Kondensator <SEP> (G)
<tb>  auf <SEP> die <SEP> Gitterspule <SEP> (B) <SEP> wirkt. <SEP> Das <SEP> Anten  nensystem <SEP> ist <SEP> ein <SEP> Dipol <SEP> Bi <SEP> und <SEP> H2.



  Small transmitter for wireless telegraphy.
EMI0001.0002
  
    The <SEP> requirement <SEP> for <SEP> small, <SEP> very <SEP> light ones
<tb> Radio telegraphy transmitters <SEP> were <SEP> to <SEP> prey <SEP> because <SEP> made it difficult <SEP> that <SEP> the <SEP> anode battery <SEP>
<tb> two- <SEP> or <SEP> triple <SEP> weight <SEP> the other <SEP>
<tb> Share <SEP> of the <SEP> small transmitter <SEP> opposite <SEP> showed.
<tb> This <SEP> disadvantage <SEP> becomes <SEP> through <SEP> the <SEP> present
<tb> Invention, <SEP> from <SEP> the <SEP> in <SEP> the <SEP> Fig.

   <SEP> 1 <SEP> and <SEP> 2 <SEP>
<tb> Exemplary embodiment <SEP> shown <SEP> is, <SEP> corrected.
<tb> Instead of <SEP> the <SEP> heavy <SEP> anode battery <SEP> is <SEP> in parallel
<tb> to <SEP> heating circuit <SEP> (battery <SEP> F) <SEP> on <SEP> Sucnmer <SEP> (E)
<tb> switched, <SEP> of <SEP> the <SEP> current impulses <SEP> of the <SEP> primary winding <SEP> of a <SEP> transformer <SEP> (C) <SEP>.
<tb> Here <SEP> <SEP> is now <SEP> the <SEP> voltage <SEP> is transformed up <SEP> and <SEP> is fed to the <SEP> tube <SEP> (A) <SEP>.

   <SEP> The
<tb> remaining <SEP> circuit <SEP> is <SEP> the <SEP> normal <SEP> three-point
EMI0001.0003
  
    switching, <SEP> where <SEP> the <SEP> feedback <SEP> to <SEP> the
<tb> grid <SEP> of the <SEP> tube <SEP> via <SEP> the <SEP> capacitor <SEP> (G)
<tb> on <SEP> the <SEP> grid coil <SEP> (B) <SEP> acts. <SEP> The <SEP> antenna system <SEP> is <SEP> a <SEP> dipole <SEP> Bi <SEP> and <SEP> H2.
