Abstract

Væsketapsregulerende additiv til anvendelse i oljebaserte bore-hullsvæsker inneholdende et løseliggjort lignittderivat og en oljesvellbar eller oljeløselig polymer. Det løseliggjorte lignittderivatet kan være oljeløseliggjort (f.eks. et lignitt/. aminkompleks) eller et vannløseliggjort (f.eks. kaustisert lignitt) og kan innarbeides i en polymer-»matriks eller tilsettes en polymer-løsning eller dispersjon i et løsningsmiddel-system.

Description

Monterbar espalier.
Oppfinnelsen vedrører en monterbar espalier, bestående av vertikale staver og horisontale mellomstykker, idet stavene er forsynt med på jevn avstand forekommende hull, og mellomstykkene er forsynt med en etter hullene gjennom stavene tilpasset kanal, idet det nye og karakteristiske er at mellomstykkene er forsynt med til de fortrinnsvis rørformede stavers form svarende endestykker og en dem forbindende flens samt at kanalene strekker seg fra den ene endedel til den annen, og at et elastisk organ avvekslende er ført gjennom hull i stavene og gjennom kanalene i mellomstykkene for på denne måte å binde sammen stavene og mellomstykkene til en espalier.
Oppfinnelsen anskueliggjøres nærmere på tegningen, hvor
Fig. 1 viser et stykke av en espalier ifølge oppfinnelsen sett fra siden,
fig. 2 viser et stykke av det vertikalt stående rør, som representerer de vertikale staver delvis i snitt.
Fig. 3 viser et horisontalt forbindelsesstykke i horisontalprojeksjon, og
fig. 4 viser samme forbindelsesstykke i vertikalsnitt, perpendikulært på bildepla-net i fig. 1.
I fig. 1 vises således tre stykker av de vertikalt stående rør 10 samt fire mellomstykker 11. Rørene er med jevne^ mellom-rom, svarende til delingen mellom mellomstykkene, forsynt med diametralt gjennom-gående hull 12, og svarende til disse hull er anordnet kanaler 13 i en fortykket del 14 på flensen 16 for mellomstykkene 11. Disse inneholder dessuten et par skålformede endepartier 17 av omtrent månesigdformet tverrsnitt, hvis utad vendte konkave sider er tilpasset etter dimensjonen av røret 10.
Ved sammenmontering av en slik espalier stikker man avvekslende gjennom kanalen 13 og hullene 14 et elastisk organ, som fortrinnsvis utgjøres av en skruefjær 18, og hver sådan skruefjær låses i begge ender ved hjelp av passende organ, f. eks. i det indre av skruen inngjengede øyeskruer 19, som derpå kan benyttes for oppheng-ning av espalieren.
En espalier av dette slag er lett å montere sammen til en hver ønsket størrelse, idet man bare behøver å kappe til et passende antall rør av rett lengde samt montere dem sammen med passende antall mellomstykker. Espalieren er dessuten lett formbar i sideretning, slik at den f. eks. kan festes på utsiden av en krum veggflate, som f. eks. en svalgang, et tårn eller lignende. Espalieren gir meget god støtte for alle slags forskjellige slyngplanter, men også for trær og busker, idet dens holdfasthet er meget stor. Espalieren kan tross dette fremstilles av billig materiale, som er meget lett i vekt og er varmebestandig, spe-sielt hårdplast for rørenes 10 vedkommende og en halvmyk plast for mellomstykke-nes 11 vedkommende. På grunn av de på vertikalsidene av espalieren foreliggende skrueøyne 19 er espalieren meget lett å montere mot den vegg eller lignende, hvor den skal gi understøttelse for forekommende slyngplanter.
I visse tilfeller vil man ikke ha espalieren så tett som vist på tegningen. Man har da store variasjonsmuligheter, idet man kan montere inn mellomstykkene med større avstand, f. eks. bare montere inn annet eller tredje hvert mellomstykke. På tilsvarende måte kan man ta bort annet hvert av rørene 10 og i deres sted mellom de to månesigdformede endepartier på mellomstykkene montere inn på forhånd tilkappede rørstykker av samme lengde som høyden av mellomstykkene. Ved passende valg av antall av på denne måte overhop-pede mellomstykker resp. hele sammen-hengende rør 10 kan man sammenbygge en espalier av praktisk talt hvilken som helst tetthet såvel i høyde- som i sideretning.

Claims (5)

1. Monterbar espalier, bestående av vertikale staver og horisontale mellomstykker, idet stavene er forsynt med på jevn avstand forekommende hull, og mellomstykkene er forsynt med en etter hullene gjennom stavene tilpasset kanal, karakterisert ved at mellomstykkene (11) er forsynt med til de fortrinnsvis rørforme-de stavers (10) form svarende endestykker (17) og en dem forbindende flens (16) samt at kanalene (13) strekker seg fra den ene endedel (17) til den annen, og at et elastisk
organ (18) avvekslende er ført gjennom hull (12) i stavene og gjennom kanalene (13) i mellomstykkene (11) for på denne måte å binde sammen stavene (10) og mellomstykkene (11) til en espalier.
2. Espalier som angitt i påstand 1, karakterisert ved at endepartiene av endestykkene består av rørsegmenter som omslutter de rørformede stavprofiler hen-imot 180°.
3. Espalier som angitt i noen av de foregående påstander, karakterisert ved at flensen (16) har en midtre, hori-sontal fortykning (14) gjennom hvilken kanalen (13) løper.
4. Espalier som angitt i noen av de foregående påstander, karakterisert ved at det elastiske organ utgjøres av en skruefjær (18), som i endene er låst ved hjelp av innskrudde øyeskruer eller kroker (19).
5. Espalier som angitt i de foregående påstander, karakterisert ved at to eller flere av mellomstykkene (11) er sam-menføyet ved hjelp av kortere rørstykker av stort sett samme høyde som mellom-stykkenes (11) høyde.
