Abstract

Fremgangsmåte og apparat for filtrering av smeltet metall, særlig aluminium.Method and apparatus for filtering molten metal, in particular aluminum.

Description

Utåndingsarrangement for gassmasker. Exhalation arrangement for gas masks.

Oppfinnelsen er beregnet på gassmasker som er utstyrt med inn-åndings- og utåndings-ventiler og består i en kombinasjon av utåndingsventilen med et munnstykke innvendig i gassmasken. Oppfinnelsen har til hensikt å forhindre at det danner seg kondens og dugg inne i maskene og på vindu eller øyeglass. The invention is intended for gas masks which are equipped with inhalation and exhalation valves and consists of a combination of the exhalation valve with a nozzle inside the gas mask. The invention is intended to prevent condensation and fog from forming inside the masks and on windows or eye glasses.

Gassmasker brukt under den første verdenskrig var i stor utstrekning beregnet på innånding og utånding gjennom filterpatronen, og de manglet ventiler for inn- og ut-åndingen. Gas masks used during the First World War were largely intended for inhalation and exhalation through the filter cartridge, and they lacked valves for inhalation and exhalation.

De mest avanserte gassmasker i dag er utstyrt med innåndings-ventiler i forbindelse med filterpatronen og en utåndingsventil montert direkte på masken. Friskluft trekkes inn gjennom filterpatronen, og utåndingsluft blåses ut av masken til fri luft gjennorn utåndingsventilen. Oppfinnelsen gjelder spesielt denne type gassmasker, hvor utåndingsventilen er montert direkte på masken. Den vedrører ikke gassmasker som ved slangeforbindelser $r kombinert med respirasjonskammer i et lukket system. Munnstykket utgjør for disse masker enten endestykket av en slange-forbindelse (U.S. pat.nr. 2.o27.392), eller det kan være tilkoblet systemet ved hjelp av et koblingsstykke, som fraskrudd tillater bytte av filterpatron (tysk pat.3ol.619) og som tilskrudd sørger for lufttett forbindelse mellom kammer, filterpatron og gassmaske. The most advanced gas masks today are equipped with inhalation valves in connection with the filter cartridge and an exhalation valve mounted directly on the mask. Fresh air is drawn in through the filter cartridge, and exhaled air is blown out of the mask to free air through the exhalation valve. The invention applies in particular to this type of gas mask, where the exhalation valve is mounted directly on the mask. It does not concern gas masks as with hose connections $r combined with a breathing chamber in a closed system. For these masks, the mouth piece forms either the end piece of a hose connection (U.S. pat. no. 2.o27.392), or it can be connected to the system by means of a coupling piece, which, when unscrewed, allows the replacement of the filter cartridge (German pat.3ol.619 ) and as screwed on ensures an airtight connection between chamber, filter cartridge and gas mask.

Oppfinnelsen har til hensikt å oppnå en billig erstatning for innermasker ved moderne gassmasker. Innermasken er likesom munnstykket kombinert med utåndingsventilen og hindrer kondens og dugg på vindu eller øyeglass. Hen innermasken hindrer ikke fuktig utåndingsluft på den dei av ansiktet som befinner seg innvendig i innermasken. "Dead space" er her ikke ubetydelig, mens man ved bruk av munnstykke kan regne den lik null. The invention aims to achieve a cheap replacement for inner masks in modern gas masks. The inner mask, like the mouthpiece, is combined with the exhalation valve and prevents condensation and fog on the window or eye glass. The inner mask does not prevent moist exhaled air on the part of the face that is inside the inner mask. "Dead space" is not insignificant here, while when using a mouthpiece it can be calculated as zero.

OppfinnelsenVstår i den spesielle kombinasjon av munnstykke og utåndingsventil. Munnstykkets gjengedel (C) er forsynt med inn-vendige gjenger. Utåndingsventilen (A) har en utvendig gjenget rørstuss (D), som stikker inn gjennom en åpning i masken rett ut for munnpartiet. Når munnstykket skrues fast på rørstussen, vil maskepartiet rundt åpningen klemmes fast mellom den utvendige ventilflate og utåndingsventilen og bevirker lufttett forbindelse av utåndingsventilen til masken. The invention resides in the special combination of mouthpiece and exhalation valve. The threaded part of the mouthpiece (C) is provided with internal threads. The exhalation valve (A) has an externally threaded pipe connection (D), which protrudes through an opening in the mask directly in front of the mouth. When the mouthpiece is screwed onto the pipe connection, the mask part around the opening will be clamped between the external valve surface and the exhalation valve and causes an airtight connection of the exhalation valve to the mask.

Tegningen viser et 2-delt munnstykke (B og C), hvor C er skrudd fast på utåndingsventilen og del B er forskyvbart festet på del C. The drawing shows a 2-part mouthpiece (B and C), where C is screwed onto the exhalation valve and part B is slidably attached to part C.

Claims (2)

1. Anordning innvendig i gass-, resp. røyk-masker, som er utstyrt med inn- og ut-åndingsventiler, beregnet på å hindre kondens i masken og dugg på vindu eller øyeglass, karakterisert ved at et med indre gjenger forsynt munnstykke (C) påskrudd utåndingsventilens ytre gjengede rørstuss (D), som er ført inn gjennom en åpning i masken, sørger for at maskepartiet rundt den nevnte åpning klemmes fast mellom utåndingsventilens (A) ytre flate og munnstykket (C) og bevirker lufttett befestigelse av utåndingsventilen (A) til masken.1.
