IPC: G01N21/3518
Filed: 1962-03-21
Abstract: 976,356. Gas analysis. BALZERS PATENTUND LIZERZ-ANSTALT. March 21, 1962 [Aug. 12, 1961], No. 10807/62. Heading G1B. A gas analysis apparatus comprises a rotary pump and an instrument for measuring a physical parameter connected by a duct directly to the exhaust chamber of the pump, whereby the pressure in and volume of the combined duct and exhaust chamber pulsate. As shown in Fig. 1, gas from a high vacuum hot extraction furnace 1 is drawn off by means of diffusion pump 4 and thence is drawn into rotary pump 2. The exhaust chamber 8 of the latter is connected by means of ducts (which form with said chamber a measuring chamber) to a heat conductivity measuring device 16, e.g. for H 2  determination. A pressure gauge 12 is also provided which gives a mean value and may be directly calibrated in units of gas quantity, e.g. a U-tube manometer or electrical manometer. The ducts may if desired by formed in a metal block in heat conducting relationship to the pump. Valve 17 opens into a further series of ducts connected to an infrared detector 26, e.g. for CO determination. An auxiliary rotary pump 22 is provided whereby initially at least the measuring chamber, andpreferably all, the ducts, may be evacuated. Thereafter valves 14, 17, 19 and 20 are closed, pumps 2 and 4 being operated but the specimen in the furnace not being heated. When heat is applied, gases begin to enter the measuring chamber and the quantity and thermal conductivity of the gas are measured. Where only H 2 , 0 2  and/or N 2  are present, the latter result is a measure of the H 2  content. The valve 17 is opened and the infra-red absorption of the gas measured. Alternatively a gas not absorbing infra-red may be allowed to enter via valve 19 before the measurement whereby the greater part of the gas tested'is rinsed into the instrument 19. As shown in Fig. 2, a throttling element 33 may be inserted into the exhaust duct of the pump 2.

Filed: 1955-04-18
Abstract: 804,721. Crank chambers. BRITISH INTERNAL COMBUSTION ENGINE RESEARCH ASSOCIATION. April 11, 1956 [April 18, 1955], No. 11107/55. Class 7(2) [Also in Group XXI] A flame-trap in an engine crank case is provided with a plurality of relatively small passageways therethrough, the structure defining the passageways being coated or adapted in use to be coated with a vaporizable substance, vaporization of which quenches the flames. In Fig. 1 a flame-trap consists of strips of wire gauze 1, one or more layers (preferably the inner layers) of which are coated with grease, circumferentially arranged within a perforated container 2 secured to the wall of door 5 of an engine crankcase in which is mounted a housing 6 carrying an explosion relief valve 7. In Fig. 2 the flame-trap consists of flat sheets of wire gauze 8 fastened to a frame 9 mounted inside the crankcase door 10 provided with a relief valve 11. The gauze assembly may be so placed that oil from lubricated moving parts of the engine reaches it directly, but it is preferred to supply it with oil from an oil feed pipe which may be connected to the lubricating system of the engine or may be separate from the lubricating system of the engine so that the supply of oil to the gauze may be continued for some time after the engine has stopped, and before re-starting whilst the engine is still hot. In Fig. 2 the oil is distributed over the gauze 8 from a perforated trough 12 supplied by an oil feed pipe 14, and in Figs. 3-5 (not shown) a series of nozzles fed from a feed pipe distribute oil over the whole surface of the gauze. A flame arrestor which stores a supply of oil against the event of an explosion occurring when the engine is stationary comprises gauzes 21, Fig. 8, and a grid formed by arcuate or other section strip metal elements 19 forming a series of receptacles for oil which are filled either by oil splash or by a perforated trough 20. The grid itself acts as a flame arrestor and if the spacing between the elements 19 is sufficiently close, some or all of the layers of gauze 21 may be unnecessary. In another embodiment, Figs. 9-11 (not shown), flametraps provided in apertures in partitions separating several crank chambers of a large multi-cylinder engine are wetted with oil from troughs supplied by a feed pipe.

Title: Inhaler
IPC: A61M16/10
Filed: 1921-04-18
Abstract: 161,969. Bretschneider, J. April 21, 1920, [Convention date]. Inhalers. - Apparatus for inhalation is so constructed as to deliver air which is under slight pressure and has passed either through a heated w a t e r receptacle or through a cooling device. In the form shown in Fig. I, air from a weighted bell 22 is delivered, together with atmospheric air induced by the injector 20, to a distributing pipe 11 whence it passes either downwards to a chamber 3 containing heated water or upwards to the space between an annular cooling chamber 5 and a ribbed inner cooler 6. A sieve 9 attached to the lower edge of a bell 8 secured to the inner cooler 6 serves to keep ice from rising when this is employed in the annular outer cooler. Air from the heater or cooler passes through nozzles 12 or 17 to saliva traps 15 to which breathing tubes A, B are connected by short lengths of rubber tube C. The tube not in use may be placed in a holder 19 so that the connection C is, kinked and the corresponding part of the apparatus shut off. An insulating partition 4 separates the heating chamber 3 from the cooler 5, 6. The air supply bell 22 is fitted with a non- return inlet valve 24 so that it may be filled merely by raising it in its outer vessel 21, and with a space 23, for water ballast to give the required pressure. In a modification, Fig. II, air under pressure is supplied by a water jet injector pump 26 mounted in the inner cooling chamber 6 and passes by a 'conduit 31 to an injector 20, as in the first modification, and thence, as indicated by the arrows, either to the space between the coolers 5, 6 or to the heater 3. A perforated plate 29 prevents escape of air through the ascending outflow pipe 30 from the inner vessel 6. The bell 8 carries a water chamber at the top to serve as ballast to keep the receptacle 6 at the lowest position shown in Fig. II.
Patent GB-899880-A (GB)
Title: Production of isonitriles
Filed: 1959-04-02
Abstract: Organic isonitriles are obtained by subjecting a N-monosubstituted formamide, in liquid phase and with cooling, to treatment with an acid halide acting as a dehydrating agent in the presence of an organic base which may be an amine or an alcoholate of an alkali or alkaline earth metal.  The N-monosubstituted formamide may be treated with the alcoholate prior to reaction with the acid halide.  The dehydrating agent may be phosphoryl chloride, phosphorus tri- or pentachloride, benzene- or toluene sulphonyl chloride, or thionyl chloride.  The N-substituent of the substituted formamide may be an alkyl, cycloalkyl, aryl, alkaryl, or aralkyl group, or a heterocyclic group, or a substituted group such as alkoxyalkyl, haloalkyl, alkoxyaryl, or haloaryl group.  The organic base may be a tertiary amine such as pyridine, an alkylpyridine, a trialkylamine, or an aryldialkylamine.  At least two molecular proportions of tertiary amine based on the formamide should be used.  Sodium, potassium, or calcium methylate, ethylate, or ter.-butylate may be used.  The reaction may be carried out in solution or suspension in an inert liquid, e.g. petroleum ether, benzene, or toluene.  In an example, N-cyclohexyl-formamide is dissolved in a mixture of pyridine and petroleum ether, and phosphorus oxychloride is added whilst the mixture is cooled in an ice bath.  After the initial reaction has subsided, the mixture is warmed and subsequently cooled again to 0 DEG C.  Water is added and the mixture is allowed to separate into two phases, and the organic phase if fractionally distilled under reduced pressure to obtain cyclohexyl isonitrile.  Benzyl isonitrile is obtained in a similar manner from N-benzylformamide.  In another example, potassium is dissolved in absolute t-butanol and then benzene and p-formanisidide are added. The mixture is cooled to 0 DEG C. and phosphoryl chloride is added. The reaction mixture is warmed, neutralized by addition of dry ice, and the solvent removed by distillation.  Benzene and water are added to the residue; the benzene layer is removed and subjected to fractional distillation to obtain p-methoxyphenyl isonitrile.  In a similar manner 2-methylphenyl isonitrile is obtained from o-formotoluidide.
