Description
Oppfinnelsen vedrører en framgangsmåte av det slag som er angitt i innledningen til patentkravet, for å frambringe tette skyer for kamuflasjeformål. The invention relates to a method of the kind stated in the introduction to the patent claim, to produce dense clouds for camouflage purposes.
Det er kjent å frambringe en tåkevegg som kan beskytte mot utilsiktet iakttagelse ved utskyting av tåkekasterlegemer fra tilsvarende utskytningsutstyr på panserkjøretøyer. It is known to produce a fog wall which can protect against accidental observation when fog thrower bodies are launched from corresponding launch equipment on armored vehicles.
De pyrrotekniske tåkesatser som brukes i disse legemer på basis av fosfor, fosforholdige satser eller HC-tåkesatser, danner en tåke som består av finfordelte syredråper eller hygroskopiske salter, så som sinkklorid, jfr. tyske patentskrifter 1.185.510, 1.191.548 og 1.300.454. Det er videre kjent å frambringe tåkeskyer ved å utstøte sterkt hygroskopiske syrer, så som klorsulfon-syre eller syreklorider, så som fosforpentaklorid, eller væsker, så som titantetraklorid eller blandinger av de nevnte syrer, syreklorider eller væsker i forbindelse med aminer, for eksempel trieetylamin, jfr. tysk offentliggjøringsskrift 2.232.763. The pyrotechnic fog kits used in these bodies based on phosphorus, phosphorus-containing kits or HC fog kits, form a fog consisting of finely divided acid droplets or hygroscopic salts, such as zinc chloride, cf. German patents 1,185,510, 1,191,548 and 1,300,454. It is further known to produce fog clouds by expelling highly hygroscopic acids, such as chlorosulfonic acid or acid chlorides, such as phosphorus pentachloride, or liquids, such as titanium tetrachloride or mixtures of the aforementioned acids, acid chlorides or liquids in conjunction with amines, for example triethylamine , cf. German publication document 2,232,763.
Videre er det kjent å frambringe tåkeskyer med fine dråper ved dispersjon av olje eller olje-vannemulsjoner ved hjelp av trykkgassgeneratorer. Furthermore, it is known to produce fog clouds with fine droplets by dispersing oil or oil-water emulsions using pressurized gas generators.
Mens den pyrrotekniske tåke i alminnelighet er forbundet While the pyrotechnic fog is generally associated
med brannfare, fare for en forgiftning fra den for det meste giftige tåke og bare liten spredning absorpsjon i det nærmeste infrarød område, har syre-, syreklorid, væske- og andre to-kom-ponent-tåker framstilt av disse med aminer, ved siden av en liten spredning og adsorpsjon i det nærmeste infrarød område først og fremst den ulempe, at de gir en akutt etsing, korrosjon og toksisitet. Olje- eller olje-vannemulsjontåker er fullstendig gjennom-trengelige for bølgelengdeområdet for det nærmeste infrarød lys (0.8 til 14 pm). with fire hazard, danger of poisoning from the mostly toxic mist and only slight scattering absorption in the near infrared region, have acid, acid chloride, liquid and other two-component mists produced by these with amines, next to of a small dispersion and adsorption in the near infrared range primarily the disadvantage that they cause acute etching, corrosion and toxicity. Oil or oil-water emulsion mists are completely transparent to the wavelength range of near infrared light (0.8 to 14 pm).
Dessuten er det fra engelsk patentskrift 638.060 kjent å danne en strøm av faste smådeler til belegnings- og lakkerings- Furthermore, it is known from English patent document 638,060 to form a stream of solid small parts for coating and varnishing
formål i form av røk. purpose in the form of smoke.
Den foreliggende oppfinnelse tar sikte på å angi en framgangsmåte av den nevnte art, som er i stand til å danne tette skyer som kan dannes hurtig og er såvel kalde, nøytrale og ugiftige som også ugjennomtrengelige for stråler fra et infra-rødapparat eller andre varmebilledapparater i den militære natts iktteknikk. The present invention aims to provide a method of the aforementioned kind, which is capable of forming dense clouds which can be formed quickly and which are both cold, neutral and non-toxic and also impervious to rays from an infrared device or other thermal imaging devices in the military night's ICT technology.
Dette oppnås ifølge oppfinnelsen ved at man går fTam som angitt i den karakteriserende del av patentkravet. This is achieved according to the invention by going fTam as indicated in the characterizing part of the patent claim.
Pulveret forstøves fint ved hjelp av drivgass eller eksplo-sivstoff eller på kort tid fra en beholder. The powder is finely atomized using propellant gas or explosives or in a short time from a container.
Ved å bruke de nevnte nøytrale, kalde og ugiftige pulver, unngår man ulemper med toksisitet og brannfare, idet pulveret forstøves lett ad kald vei. Den vesentlige fordel ved fram-gangsmåten ifølge oppfinnelsen består imidlertid i, at den militære nattsiktteknikk, særlig bruken av varmebilledapparater, ikke er i stand til å gjennomtrenge ,den kunstige støvsky og opptegne et varmebilde aA|i det orn^de som ligger bak skyen. By using the aforementioned neutral, cold and non-toxic powders, the disadvantages of toxicity and fire hazards are avoided, as the powder is easily atomized in a cold way. The significant advantage of the method according to the invention, however, consists in the fact that the military night vision technique, in particular the use of thermal imaging devices, is not able to penetrate the artificial dust cloud and record a thermal image of the area behind the cloud.

Som drivgass kan det også brukes-'frigen eller drivgass fra gassgeneratorer. Utlesningen eller frigivelsen av trykkgass på pulveret i beholderne skjer fortrinnsvis elektrisk, for eksempel ved påvirkning av et pyxroteknisk kraftelement eller et elektrisk-mekanisk element. Free gas or propellant gas from gas generators can also be used as propellant gas. The reading or release of compressed gas on the powder in the containers preferably takes place electrically, for example by the action of a pyrotechnic power element or an electro-mechanical element.
Utstøtningen av pulveret skjer gjennom et stigerør i det indre av pulverbeholderen, hvilket rør munner ur i en egnet dyseåpning for finfordeling i den omgivende luften. Herunder kan det på vanlig måte tas hensyn til en adskillelse mellom frigivelsen av trykkgassen og pulveret og utstrømningen av pulveret gjennom dysen, for eksempel ved hjelp av en ekstra ventil og/eller en sperreskive som må brytes opp. På denne måten blir det mulig å foreta en hurtig og ufarlig dannelse av tåke-skyen . The ejection of the powder takes place through a riser pipe in the interior of the powder container, which pipe opens into a suitable nozzle opening for fine distribution in the surrounding air. Here, account can usually be taken of a separation between the release of the pressurized gas and the powder and the outflow of the powder through the nozzle, for example by means of an additional valve and/or a barrier disc that must be broken up. In this way, it becomes possible to make a quick and harmless formation of the fog cloud.
