KLASS INTERNATIONELLSVENSK B65 g81 e:143 PATENT- OCH REGISTRERINGSVERKET Ans. 627111964 inkom den 22/1964 utlagd den 27/9 196 METAL CONTAINERS LTD, LONDON, STORBRITANNIEN Behfillare for tryekvfitska Uppfinuare: 0 J van Leer och C Ragettli Prioritet begard frdn den 24 maj och 24 oktober 1963 (Storbritannien) Foreliggande uppfinning hanfor sig till en beballare for tryckvatska. Ehuru den i forsta hand avser behallare for forpackning, lagring, transport och distribution av petroleumgas i flytande form, t. ex. butan eller propan, dr uppfinningen dock icke begransad till detta anvandningsomrade utan kan tillampas pa vilka som heist behallare for tryckvatskor. CLASS INTERNATIONAL SWEDISH B65 g81 e: 143 PATENT AND REGISTRATION AGENCY Ans. 627111964 received on 22/1964 issued on 27/9 196 METAL CONTAINERS LTD, LONDON, UNITED KINGDOM Applicants for Tryequite Inventors: 0 J van Leer and C Ragettli Priority requested from 24 May and 24 October 1963 (United Kingdom) The present invention relates to a beballare for pressurized water. Although it primarily refers to containers for packaging, storage, transport and distribution of petroleum gas in liquid form, e.g. butane or propane, however, the invention is not limited to this field of application but can be applied to any container for pressurized water tanks.
Om vanliga behallare av detta slag blir Oyerhettade, t. ex. pa grund av brand i den byggnad, dar de är placerade, foreligger stor risk for explosion och sadana explosioner har oak- sâintraffat. If ordinary containers of this kind become Oyerhettade, e.g. due to fire in the building where they are located, there is a great risk of explosion and such explosions have also occurred.
Foreliggande uppfinning avser en behallare, som icke exploderar, ndr den overhettats, eller vid vilken explosionsrisken avsevart reducerats. The present invention relates to a container which does not explode when overheated, or in which the risk of explosion has been considerably reduced.
Behallaren enligt uppfinningen är vid normal temperatur gas- och vatsketat, men nar den uppnatt en pa forhand bestamd temperatur, blir den poros over atminstone en del av sin vagg, sä att gasen kan stromma ut i ett stort antal sma strOmmar, vilka, om gasen är brannbar, kan fatta eld men endast ger sma lagor. Explosionsrisken är emellertid eliminerad eller reducerad, eftersom gasen kan strOm- maoch ytterligare tryckokning salunda undvikes. The container according to the invention is gas- and liquid-chained at normal temperature, but when it has reached a predetermined temperature, it becomes porous over at least a part of its cradle, so that the gas can flow out in a large number of small streams, which, if the gas is flammable, can catch fire but only gives small layers. However, the risk of explosion is eliminated or reduced, as the gas can flow and further pressure increase is thus avoided.
Foreliggande uppfinning avser saledes en behallare for tryckviitska, t. ex. petroleumgas flytande form, bestaende av ett skal, som är porost atminstone Over en del av sin yta, varvid den porosa delen av skalet är tillsluten av ett forslutningselement, vilket atminstone delvis är framstallt av ett material, som är ogenomtrangligt for gas och vatska vid normal temperatur men som blir genomslappligt, ndr det upphettas till en fOrutbestamd 'Ogre tern peratur, och darigenom tillater gas att strain-ma ut fran behallaren tvars genom det porosa skalet eller en del darav. The present invention thus relates to a container for pressure vessels, e.g. petroleum gas liquid form, consisting of a shell, which is porous at least over a part of its surface, the porous part of the shell being closed by a sealing element, which is at least partly made of a material which is impermeable to gas and liquid in normal temperature but which becomes permeable when heated to a predetermined temperature, thereby allowing gas to strain out of the container through the porous shell or part thereof.
Materialet kan bli genomslappligt genom att det kryper, flyter i plastiskt hanseende, borjar skumma, smalter, brister eller sOnderdelas pa annat att. The material may become permeable as it creeps, floats in the plastic sense, begins to foam, melts, breaks or decomposes in other ways.
Nar behidlaren enligt uppfinningen upphettas till en temperatur over den. pa forhand bestamda hogre temperaturen genom brand eller i oppen eld, kommer forslutningselementet att krypa, flyta i plastiskt hanseende, borja skurnma eller sonderdelas, varigenom gasen far mojlighet att strOmma ut lean behallaren till den omgivande atmosfaren. Detta utstrOmmande sker emellertid icke i store kompakta kvantiteter utan i ftera sma shorn-mar, eftersom gasen slappes ut genom porerna i det porosa skalet eller den porosa delen av skalet. Aven om dessa strommar fattar eld, da gasen är brannbar och temperaturen tillrackligt hog for att antanda gasen, leder detta icke till nagon explosion eller atminstone blir explosionsrisken avsevart mindre. Behallaren kommer att se ut som en elmseld. When the container according to the invention is heated to a temperature above it. predetermined higher temperature by fire or in open fire, the sealing element will creep, float in a plastic sense, begin to scurry or split, whereby the gas is allowed to flow out of the lean container to the surrounding atmosphere. However, this outflow does not occur in large compact quantities but in rather small horns, since the gas is released through the pores in the porous shell or the porous part of the shell. Even if these streams catch fire, as the gas is flammable and the temperature is high enough to ignite the gas, this does not lead to any explosion or at least the risk of explosion becomes considerably less. The container will look like an electric fire.
Enligt en utforingsform av uppfinningen är behallarens skal porost Over i huvudsak hela sin yta, varvid forslutningselementet bestar av en inre bekladnad av skalet ifraga. Skalet kan besta av ett tradlindat kdrl, som har en vaggtjocklek, vilken är tillrackligt liten for att kunna ge den Onskade porositeten. According to an embodiment of the invention, the shell of the container is porous Over substantially its entire surface, the sealing element consisting of an inner lining of the shell in question. The shell may consist of a wire-wrapped kdrl, which has a cradle thickness which is sufficiently small to be able to give the desired porosity.
Enligt en alternativ utforingsform av uppfinningen bestar skalet av en yttre vagg, som är pords eller utbildad med en poros del och en inre vagg, varvid vaggarna Maga har lilinande form och val passer i varandra. Den inre vaggen är utbildad med en oppning, som 2 tackes av den porlisa delen av den yttre vasgen, varvid forslutningselementet bestar av en stangningsanordning for Oppningen och stangningsanordningen atminstone delvis är framstalld av ett material, som tillater gasen att stromma ut frail den inre vaggen, nir den upphettats till den pa forhand bestamda, hog-re temperaturen. According to an alternative embodiment of the invention, the shell consists of an outer cradle, which is pored or formed with a porous part and an inner cradle, the cradles Maga having a lilac shape and choice fitting into each other. The inner cradle is formed with an opening which is thanked by the porous part of the outer cradle, the closing element consisting of a closing device for the opening and the closing device being at least partly made of a material which allows the gas to flow out of the inner cradle. when it has been heated to the predetermined, higher temperature.
Uppfinningen beskrives narmare i det följande under hanvisning till bifogade ritning, ddr fig. 1 är en partiell vertikal tvaisektion saint sidovy av en utforingsform av en enligt uppfinningen konstruerad behallare, fig. 2 är en liknande vy av en annan utf8ringsform av uppfinningen och fig. 3 är en liknande vy av annu en annan utforingsform av uppfinningen. The invention is described in more detail in the following with reference to the accompanying drawing, in which Fig. 1 is a partial vertical two-section side view of an embodiment of a container constructed according to the invention, Fig. 2 is a similar view of another embodiment of the invention and Fig. 3 is a similar view of yet another embodiment of the invention.
I fig. 1 visas en behallare 10 med ett skal, som bestar av en yttre vagg 11 och en inre vagg 12. De tva vaggarna har liknande form och passar val in i varandra. Bada vaggarna är porosa Over i huvudsak hela sin yta och i den lampligaste utfOringsformen i fig. 1 be-star de yttre och inre vaggarna i behallareskalet av tradlindade karl, varvid skalets totala vaggtjocklek är tillrackligt liten for att ge onskad porositet. Vid lindningen av hartsimpregnerade eller hartsfuktade tradar eller fibrer bildas ett visst antal mellanrum. Dessa kan tilltappas genom att ett stort antal skikt lindas pa varandra. Det har visat sig, att behallaren enligt foreliggande uppfinning är tillrackligt stark for det andamal, som den skall tjana, nar vaggtjockleken är forhallandevis liten, sá att antalet pa varandra anbragta skikt icke är tillrackligt stort for tillslutning av mellanrummen, och den Onskade porositeten i behallarskalet enligt uppfinningen erhalles salunda som en foljd av framstallningsmetoden. Fig. 1 shows a container 10 with a shell, which consists of an outer cradle 11 and an inner cradle 12. The two cradles have a similar shape and fit into each other. Both cradles are porous Over substantially their entire surface, and in the most suitable embodiment in Fig. 1, the outer and inner cradles in the container shell consist of wire-wound male, the total cradle thickness of the shell being sufficiently small to give the desired porosity. When winding resin-impregnated or resin-moistened threads or fibers, a certain number of gaps are formed. These can be tapped by wrapping a large number of layers on top of each other. It has been found that the container according to the present invention is sufficiently strong for the purpose it is to serve when the rock thickness is relatively small, so that the number of layers applied to each other is not sufficiently large to close the gaps, and the desired porosity in the container shell according to the invention is thus obtained as a result of the manufacturing method.
Skalet 11, 12 är forsett med ctt forslutningselement i form av ett hire foder 13, som är ogenomtrangligt for gas och vatska vid normal temperatur men som kryper, flyter plastiskt, smalter, spricker eller pa annat satt sonderdelas och blir otatt, nar det upphettas till en forutbestamd h6gre temperatur, varigenom gas avgar Iran behallaren tvars genom det portisa skalet 11, 12. Gasen avgar salunda i talrika strommar i stallet for i stora hornpakta mangder och det inre tryeket i behtillaren okas icke i sadan grad, att nagon fara for explosion fOreligger. Aven om dessa strommar fatta eld, om gasen är brannbar och temperaturen ar tillrdckligt hog for antandning av gasen, intraffar icke nagon explosion eller atminstone reduceras explosionsrisken avsevart. Behallaren kommer att brinna som en elmseld. The shell 11, 12 is provided with a sealing element in the form of a hire liner 13, which is impermeable to gas and liquid at normal temperature but which creeps, floats plastically, melts, cracks or is otherwise disassembled and taken out when heated to a predetermined higher temperature, whereby gas emits the Iran container transversely through the portisa shell 11, 12. The gas emits salunda in numerous streams instead of in large horn-packed quantities and the internal pressure in the container is not increased to such an extent that there is no danger of explosion . Even if these currents catch fire, if the gas is flammable and the temperature is sufficiently high for the gas to ignite, no explosion occurs or at least the risk of explosion is significantly reduced. The container will burn like an electric fire.
Behallaren Or forsedd med en bottenplugg 14, som tillsammans med en lasring 15 omfattar den kant, som omgiver en central Oppning i den yttre vaggen 11 av behallarskalet. liknande satt finnes ett topphalsstycke 16, som Or anordnat att upptaga exempelvis en skruvgdngad utloppsventil (icke visad) och som Mlles i lage medelst en lasring 17. The container Or is provided with a bottom plug 14, which together with a welding ring 15 comprises the edge which surrounds a central opening in the outer cradle 11 of the container shell. similarly, there is a top neck piece 16, which Or is arranged to receive, for example, a screw-forced outlet valve (not shown) and which Mlles in position by means of a welding ring 17.
Den forutbestamda 'Ogre temperatur, vid vilken fodret 13 blir otatt, uppgar lampligen till Over 100° C. Nar behallaren Or avsedd att anvandas for propan, Or denna temperatur lampligen c:a 130° C och nar behallaren shall innehalla butan, utgor ifragavarande temperatur c:a 160° G. The predetermined 'Ogre temperature, at which the feed 13 is taken, is suitably over 100 ° C. When the container Or is intended to be used for propane, Or this temperature is probably about 130 ° C and when the container is to contain butane, the temperature in question is 160 ° C.
Det har visat sig, att fordelaktiga resuItat erhallas om fodret 13 framstalles av en sampolymer av epoxiharts och Thiokol, som Or ett varuma.rke for ett syntetiskt gummi pa basis av alkenpolysulfid. Tillfredsstallande resultat har aven erhallits med anvandning av polyestrar, speciellt en mjukgjord (flexibilized) polyester som fodermaterial. Andra material, som kommer ifraga och som visat sig lampliga for andamalet, Or epoxi/polyestersampolymerer, en Thiokol-monopolymer och syntetiska hartser inkl. polyestrar, som atminstone delvis Or baserade p0 isoftalsyra och/eller adipinsyra. It has been found that advantageous results are obtained if the liner 13 is made from a copolymer of epoxy resin and Thiocol, which is a trademark of a synthetic rubber based on alkene polysulfide. Satisfactory results have also been obtained with the use of polyesters, especially a flexibilized polyester as lining material. Other materials which come into question and which have proved suitable for the spirit, Or epoxy / polyester copolymers, a Thiocol monopolymer and synthetic resins incl. polyesters which are at least partially Or based on isophthalic acid and / or adipic acid.
Sum anti-skummedel kan tillsattas glycidyleter av versatinsyra. Andra tillsatser, som givit lampliga resultat, är kolloidal kiseldioxid. Some anti-foaming agents may be added glycidyl ether of versatic acid. Other additives which have given suitable results are colloidal silica.
Det har vidare visat sig, att behallare enligt uppfinningen har ytterligare fordelar bortsett frail att explosionsrisken elimineras eller reduceras avsevart. Nar en belt eller delvis fylld behallare far falla, har det inrc fodret 13 och/eller den inre vaggen 12, nar behallarskalet gjorts dubbelvaggigt, benagenhet att skiljas frail den yttre vaggen 11. Genom att den yttre vaggen i detta fall Or genomtranglig eller poros, kan omgivande luft langsamt intrdnga mellan de hada vaggarna eller mellan vaggen och fodret, varigenom en chockabsorberande effekt erhalles. It has further been found that containers according to the invention have additional advantages apart from the fact that the risk of explosion is eliminated or reduced considerably. When a belt or partially filled container is allowed to fall, the inner liner 13 and / or the inner cradle 12, when the container shell is made double-lobed, has a tendency to be separated from the outer cradle 11. In this case the outer cradle is permeable or porous, ambient air can slowly penetrate between the hada cradles or between the cradle and the lining, whereby a shock-absorbing effect is obtained.
Vid den i fig. 2 visade utforingsformen Or behallaren betecknad med 10 och bestar av ett skal, som Oven utgOres av en yttre vagg 11 och en hire vagg 12, vilka hada ha lika form och tatt passa i varandra. Bottenpartiet av den inre vaggen 12 Or utformat med en Opp-fling, som tackes av en del av den yttre vaggen 11. Atminstone detta parti av den yttre vaggen Or porost. Alternativt kan den yttre vaggen 11 vara por8s Over i huvudsak sin hela yta och i detta fall skall den inre vaggen 12 vara ogenomtranglig for gas och vatska atminstone vid normal temperatur, t. ex. genom att vara impregnerad med ett lampligt amne eller genom att den Or forsedcl med ett oge- 3 nomtrangligt foder (ej visat), sasom angives I samband med utforingsformen enligt fig. 1. oppningen i den inre vaggen 12 och motsvarande porosa parti i yttervaggen 11 tillslutas medelst ett fOrslutningsorgan 18, vilket organ eller »bottenkaka» helt framstallts av ett material, som sonderdelas eller pa annat satt tillater gasen avga fra'n den inre vaggen som en foljd av upphettning till den fOrutbestamda hogre temperaturen. Ej heller har avgar gasen i stora kompakta mangder utan tvartom i form av ett flertal sma gasstrommar genom porerna i det porosa, yttre vaggpartiet, som tacker oppningen i den inre vaggen. Aven bar forhindras salunda gasen fran att framkalla en omattlig tryckokning, och om den avga.ende gasen ar brannbar och fattar eld erMlles endast ett flertal sma lagor. In the embodiment Or shown in Fig. 2, the container is denoted by 10 and consists of a shell, which is also formed by an outer cradle 11 and a hire cradle 12, which had had the same shape and fitted into each other. The bottom portion of the inner cradle 12 Or formed with an Opp-fling, which is thanked by a part of the outer cradle 11. At least this portion of the outer cradle Or porous. Alternatively, the outer cradle 11 may be porous Over substantially its entire surface and in this case the inner cradle 12 should be impermeable to gas and liquid at least at normal temperature, e.g. by being impregnated with a suitable substance or by providing it with an impermeable liner (not shown), as indicated in connection with the embodiment according to Fig. 1. the opening in the inner cradle 12 and the corresponding porous portion in the outer cradle 11 is closed by means of a closing means 18, which means or "bottom cake" is made entirely of a material which is probed or otherwise allows the gas to escape from the inner cradle as a result of heating to the predetermined higher temperature. Nor does the exhaust gas in large compact quantities but on the contrary in the form of a plurality of small gas drums through the pores in the porous, outer rock portion, which thank the opening in the inner rock. The gas must also be prevented from producing an excessive pressure increase, and if the exhaust gas is flammable and catches fire, only a few small layers are formed.
Sasom tidigare angivits i samband med fig. 1 hr behallaren fOrsedd med en. bottenplugg 14 och en samverkan.de lasring 15 och ett topphalsstycke 16 anordnat att mottaga en skruvgangad utloppsventil (icke visad) och fOrenat med en lasring 17. As previously stated in connection with Fig. 1 hr the container is provided with a. bottom plug 14 and a cooperating laser ring 15 and a top neck piece 16 arranged to receive a threaded outlet valve (not shown) and connected to a laser ring 17.
Den i fig. 3 visade behallaren med beteckningen 10 ar aven fOrsedd med ett skal, som bestar av en yttre vagg 11 och en inre vagg 12, varvid vaggarna har lika form och tatt passar i varandra. Vid denna utforingsform jr topp-partiet av den inre vaggen 12 utformat med en Oppning, som tackes av ett parti av den yttre vaggen. Atminstone detta parti av den yttre vaggen är pothst, men a.yen bar kan den yttre vaggen vara porOs Over i huvudsak sin hela yta, forutsatt att innervaggen hr gjord ogenomtranglig for gas och vatska vid atminstone normal temperatur, t. ex. genom att den hr impregnerad eller ftirsedd med ett ogenomtrangligt inre foder eller ett yttre overdrag. The container 10 shown in Fig. 3 is also provided with a shell, which consists of an outer cradle 11 and an inner cradle 12, the cradles having the same shape and fitting into each other. In this embodiment, the top portion of the inner cradle 12 is formed with an opening which is thanked by a portion of the outer cradle. At least this portion of the outer cradle is pothst, but a.yen bare, the outer cradle may be porOs Over substantially its entire surface, provided that the inner cradle here is made impermeable to gas and liquid at at least normal temperature, e.g. in that it is impregnated or provided with an impermeable inner lining or an outer coating.
Aven vid denna utforingsform hr Oppningen I den inre vaggen 12 och motsvarande porOsa parti av den yttre vaggen 11 forseglade me-deist ett forslutningsorgan. Detta innefattar ett topphalsstycke 16, som Ur anordnat att mottaga en skruvgangad utloppsventil (ej vi-sad) och som hr fOrbundet med en »toppkaka» 19 medelst en monteringsring 20. Toppkakan hr framstalld av ett material, som sonderdelas eller pa annat salt medgiver, att gas kan avgà frail innervaggen vid upphettning till en forutbestamd hogre temperatur. I detta fall strOmmar gasen omkring halsstyekets 16 flans, intranger i utrymmet mellan den yttre och den inre vaggen och avgar slutligen genom porerna antingen i hela den yttre vaggen eller det porosa partiet dari, varigenom samma effekt erhalles, som beskrivits i samband med anordningarna enligt fig. 1 och 2. Also in this embodiment the opening in the inner cradle 12 and the corresponding porous portion of the outer cradle 11 are sealed by means of a sealing member. This comprises a top neck piece 16, which is arranged to receive a screw-threaded outlet valve (not shown) and which is connected to a "top cake" 19 by means of a mounting ring 20. The top cake is made of a material which is probed or on another salt, that gas can escape from the inner cradle when heated to a predetermined higher temperature. In this case, the gas flows around the flange of the neck piece 16, penetrates into the space between the outer and the inner cradle and finally exits through the pores either in the entire outer cradle or the porous portion therein, whereby the same effect is obtained as described in connection with the devices of fig. 1 and 2.
Vid utforingsformerna enligt fig. 2 och 3 är lampligen atminstone den ringformiga, perifera kanten av forslutningsorganet framstand av ett material, som är tillrackligt bojligt for att verka som en utvidgningsskarv mellan kanten av innervaggen 12, som omger oppningen dari, och intilliggande ringformiga del av den yttre vaggen 11. Darigenom forhindras bildning av otatheter, dâ t. ex. ombehallaren tappas, kanten omkring oppningen i den inre vaggen och intilliggande del av den yttre vaggen forskjutas i forhallande till varandra eller t. o. m. atskiljas och ett gap bildas mellan dem. In the embodiments of Figs. 2 and 3, at least the annular peripheral edge of the closure member is suitably made of a material which is sufficiently flexible to act as an expansion joint between the edge of the inner cradle 12 surrounding the opening therein, and adjacent annular portion of the closure member. outer cradle 11. This prevents the formation of otatheter, e.g. the container is dropped, the edge around the opening in the inner cradle and the adjacent part of the outer cradle are displaced in relation to each other or even separated and a gap is formed between them.
Det porosa partiet i behallareskalet eller den yttre vaggen kan vara belagna var som heist exempelvis i den nedre delen av behallaren, sasom visas i fig. 2 eller i toppdelen eller ovre delen, sasom visas i fig. 3. Denna senare placering hr att foredraga. Da.rigenom undvikes eller atminstone reduceras risken att forslutningselementet i form av ett foder eller i form av ett fOrslutningsorgan kyles av vatskan i behallaren, sa att den av det sOnderdelbard forslutningselementet bildade »sdkerhetsventilen» reagerar orimligt langsamt. The porous portion of the container shell or outer cradle may be coated anywhere, for example, in the lower part of the container, as shown in Fig. 2 or in the top part or the upper part, as shown in Fig. 3. This latter location is preferable. This avoids or at least reduces the risk that the closing element in the form of a liner or in the form of a closing member is cooled by the liquid in the container, so that the "safety valve" formed by the subdivided closing element reacts unreasonably slowly.
Vid utforingsformerna enligt fig. 2 och 3 är den forutbestamda hOgre temperatur, -vid vii-ken. tillslutningsorganet eller ett parti darav sonderdelas eller pa annat salt tillater gas att lampligen Over 100° C, och nar behallaren innehaller propan, är denna temperatur c:a 130° C och vid propan är en lamplig temperatur c:a 160° C. In the embodiments according to Figs. 2 and 3, the predetermined higher temperature is at the week. the closing member or a portion thereof is separated or on other salt allows gas to suitably exceed 100 ° C, and when the container contains propane, this temperature is about 130 ° C and at propane a suitable temperature is about 160 ° C.
Det material, av vilket forslutningsorganet eller en del darav framstalles, kan utgoras av ett i varme hardbart harts inkl. ett reaktivt mjukgoringsmedel (flexibilizer). Materialet kan exempelvis innehalla eller vara baserat pa ett epoxiharts. Den vanligen tillsatta hardaren kan utgOras av en aminhardare eller en anhydridhardare, sasom en polymer anhydridhardare. The material from which the sealing member or a part thereof is made can consist of a heat-curable resin incl. a reactive plasticizer (flexibilizer). The material may, for example, contain or be based on an epoxy resin. The commonly added hardener may be an amine hardener or an anhydride hardener, such as a polymeric anhydride hardener.
Polysulfid kan anvandas som mjukgorare. Polysulfide can be used as a plasticizer.
Mycket tillfredsstallande resultat ha erhallits med anvandning av en blandning av 100 delar av ett bojligt epoxiharts, 100 delar polysulfidmjukgrare och 10 delar aminhardare. Lampligen anvandes ett b011igt epoxiharts med en epoxiekvivalent av 215-800. Aminhardaren har lampligen en aminekvivalent av storleksordningen 50. Very satisfactory results have been obtained using a mixture of 100 parts of a flexible epoxy resin, 100 parts of polysulfide plasticizer and 10 parts of amine hardener. A flexible epoxy resin having an epoxy equivalent of 215-800 was used. The amine hardener suitably has an amine equivalent of the order of 50.
Det i varme hardbara materialet kan liven. innehalla en polyester pa basis av isoftalsyra eller adipinsyra eller en blandning av sadana polyestrar, varvid metyletylketonperoxid anvandes som katalysator och polysulfid som mjukg8rare. Polyestern pa basis av adipinsyra ger ett mera elastiskt material an polyestern pa basis av isoftalsyra, som under vissa omstandigheter kan vara fordelaktig. 4 Fastan uppfinningen beskrivits i samband med lampliga utfOringsformer, är det tydligt att uppfinningen icke ar begransad till dessa. Om exempelvis ett forslutningselement i form av ett rare foder visats och beskrivits, kan det mycket val i stallet utgOras av ett yttre over-drag eller ett utvandigt pafort forseglingsorgan, som halt eller delvis framstallts av ett material, som sonderdelas eller ph annat satt tillater avgang av gas som en foljd av upphettning till en forutbestamd hogre temperatur. The heat curable material can life. contain a polyester based on isophthalic acid or adipic acid or a mixture of such polyesters, methylethyl ketone peroxide being used as catalyst and polysulfide as plasticizer. The polyester based on adipic acid gives a more elastic material than the polyester based on isophthalic acid, which in some circumstances can be advantageous. Although the invention has been described in connection with suitable embodiments, it is clear that the invention is not limited to these. If, for example, a closure element in the form of a rarer liner is shown and described, the lot of choice in the stable can be constituted by an outer cover or an external pafort sealing member, which is wholly or partly made of a material which is probed or otherwise allows departure of gas as a result of heating to a predetermined higher temperature.
