Title: Improvements in or relating to electrical resistances and electrical heaters
IPC: F24H3/00
Filed: 1934-11-05
Abstract: 443,170. Grid resistances. HAMILTON, B. H. N. H., 8, Overstrand Mansions, Battersea, London. Nov. 5, 1934, No. 31794. [Class 37] [See also Group XI] An electric resistance for heating or other purposes is made from a sheet of expanded metal or intermediate expanded metal, i.e. metal slotted as if for expanded metal, but not stretched, having two selvedge edges, by cutting it along lines K1, K2 from the two selvedge edges alternately at right angles to these edges so as to give a zigzag shape, the pieces between the cuts being then bent along the lines Q, R at right angles to the original plane of the sheet. The slots K1, K2 may be spaced by the length of half a mesh of the metal as shown, or by a whole mesh or more. Means for supporting the resistances at their ends and connecting them are described ; to allow for expansion they are preferably built up under slight tension. Specification 397,932 is referred to.

Title: Improvements in or relating to gas generators
Inventor: STANDEN DESMOND LEONARD ERNEST
IPC: F02B71/06
Filed: 1964-08-05
Abstract: 1,067,233. Engine starter and like cartridges. MINISTER OF AVIATION. Aug. 3, 1965 [Aug. 5, 1964], No. 31802/64. Heading F3A. [Also in Division Fl] A device for generating high-pressure gases comprises a cylinder 11 having a closed end 12 into which a gas outlet 13 is welded. The opposite end 14 is enlarged and recessed to receive a cup-shaped closure 15 held against a sealing ring 17 by an annular nut 18. The closure 15 has a hollow stem 25 housing an igniter 26, which may be fired electrically. The annular wall of cup 15 is spaced from the cylinder 11 and houses an annular charge 21 of cordite or other slow-burning explosive. Filter units 23 are placed over the charge 21. One end of a cylindrical metal wall 24 fits into the mouth of cup 15 and the other end is closed by a cover 27 within which are further filter units 28. The outlet tube 13 extends through the cover 27 and the diameter of both cover 27 and wall 24 is such that an annular space exists between these members and cylinder 11, serving to protect the cylinder 11 from the temperatures generated within the wall 24, when fuel sprayed therein through a device 31 is ignited. After charge 21 is ignited by igniter 26, the filtered gases enter the combustion chamber within wall 24 and, when a predetermined pressure and temperature is reached, fuel is sprayed in through opening 32 and ignited by the hot gases. The process becomes self-sustaining after the cordite has burnt out and the gas pressure in outlet 13 is dependent upon the rate of fuel supply. This rate may be automatically controlled by servo-means in response to pressure within the device.

Filed: 1930-10-23
Abstract: 364,223. Explosives. KNIAZYKOWSKI, E. BAZYLEWICZ-, and PARTYKA, K., Sochaczew, Poland. Oct. 23, 1930, No. 31917. [Class i) (ii).] Smokeless powder is gelatinized and extruded in the form of a, continuous solid cylindrical thread having a diameter of about 0-3-1-5 mm. according to the kind of powder, the thread containing 130- 130 per cent of solvent; then according to this invention, it is subjected to the following steps. The thread is cut into short lengths of about 20 cm., superficially dried for example by subjecting the cut threads to a liquid or gas at 50‹ C. for 1 to 2 minutes, and plunged for about 10 to 25 minutes into a fluid, e.g. water, at about 45‹-80‹ C. which does not act chemically on the powder but causes the evaporation of solvent from the core of the cut threads and the blowing of a channel throughout the length of the cut threads. Aniline, phenyl urea, nitrites, or nitrous or other reducing acid may be added to the fluid of the bath to the extent of 0À1-1À0 per cent. The cut threads now in the form of short tubes having a thickness of about 0-03-0-] mm. are further cut into grains in the usual way, preferably while still moist, and the grains are dried, soaked, polished, graphited or coated with camphor or centralite. The smokeless powder may contain 0-1-0-5 per cent of graphite, 6-10 per cent of water, and 0.4-1-2 per cent of diphenylamine or urea derivatives. The most suitable smokeless powder is a nitrocellulose containing 12-7-13 per cent of nitrogen; but old rifle and ordnance powder.s may be used by gelatinization with 90-160 per cent of alcohol-ether, acetone, or other solvent.

Abstract: 1508130 Transistor oscillators THORN ELECTRICAL INDUSTRIES Ltd 22 July 1975 [24 July 1974] 32761/74 Heading H3T [Also in Division H2] In an emergency lighting system in which, when the mains fail, a fluorescent lamp 24 is supplied by a battery via an inverter 19, the inverter consists of a transistor 25 which automatically becomes conductive when the mains fail, current then flowing through the primary 27 of a current transformer 28 and the primary 26 of the inverter transformer 21. As soon as transformer 28 saturates, owing to cascade action, the primary current collapses causing the secondary current to kick back and the transistor 25 to switch off. Similarly, the current in the primary of transformer 21 reverses and A.C. is induced in the secondary. The value of variable resistor 33 governs the saturation time of transformer 28 and thus the inverter output. A boosting circuit 22 is provided to initially boost the output of the inverter for a predetermined time by connecting a resistor 38 across variable resistor 33.

Title: Improvements in and relating to the decarboxylation of higher fatty acids
Inventor: CHESROWN RUSSELL
IPC: C07C45/48
Filed: 1956-10-26
Abstract: Higher fatty acids are decarboxylated by heating a feed mixture containing acids having from 8 to 22 carbon atoms with or without fatty acids containing from 1 to 22 carbon atoms in the molecule to a temperature of at least 340 DEG C., separately heating a magnesium decarboxylation catalyst to a temperature of at least 340 DEG C., and then bringing the feed mixture into contact with the catalyst.  By this means the magnesium catalysts are conserved and the formation of soaps is substantially prevented.  The preferred catalysts are magnesium oxide and magnesium hydroxide and preferably the acids and catalyst are heated to a temperature of at least 360 DEG  C.  If the fatty acids containing 8-22 carbon atoms are heated alone symmetrical ketones are obtained, if they are heated with other acids containing 2-22 carbon atoms unsymmetrical ketones are obtained and if they are heated with formic acid aldehydes are obtained.  In the examples: (a) a mixture of lauric acid and acetic acid is heated to 360-370 DEG  C. and passed over a magnesium oxide catalyst heated to 370-380 DEG C. to give methylundecyl-ketone; (b) lauric acid is reacted with formic acid under similar conditions to give lauraldehyde with some laurone and (c) stearic acid is similarly reacted with formic acid to give stearaldehyde with some stearone.
