Title: Improvements in fuel supply systems for reaction chambers
Inventor: WELCH DOUGLAS FRANCIS
IPC: F02K9/68
Filed: 1953-10-22
Abstract: 749,921. Generating combustion products under pressure. BRITISH-THOMSONHOUSTON CO., Ltd. Oct. 22, 1954 [Oct. 22, 1953], No. 29230/53. Class 51(1). An apparatus for producing a flow of gaseous working fluid, which may be supplied for example to a turbo-starter of a prime mover, comprises an auxiliary reaction chamber 2 and a main reaction' chamber 1, hot gases produced by decomposition of a monofuel within the auxiliary chamber passing into the main chamber. The flow of hot gases is so directed upon admission to the main chamber as to impinge substantially directly upon a jet of monofuel injected into the main chamber whereby atomisation of the monofuel is effected. The hot gases issue into the main chamber 1 through a nozzle 5 which is disposed opposite the nozzle 6 through which the monofuel is injected. The gases from the main chamber pass through an outlet nozzle 7. The auxiliary chamber has a monofuel supply at 3 and a heater 4. The hot gases from the auxiliary chamber may alternatively be led through a pipe to the vicinity of the monofuel injected through the nozzle 6 in which case the nozzles 5 and 6 are not necessarily in alignment. Specifications 726,897, 731,977 and 749,920 are referred to.

Filed: 1927-11-02
Abstract: 302,775. British Celanese, Ltd., and Ellis, G. H. Nov. 2, 1937. Yarns &c., treating with liquids. - Yarns, threads, &c. made of or containing cellulose acetate or other organic acid esters of cellulose, e.g. cellulose formate, propionate or butyrate, or the products (" immunized cotton ") obtained by treating alkalized cellulose with sulphochlorides, e.g. with p-toluene sulphochloride, or made of or containing cellulose ethers, e.g. methyl, ethyl or benzyl cellulose or the corresponding condensation products of cellulose and glycols or other polyhydric alcohols, are loaded or mordanted, and, in the case of the esters, partially saponified, by treating them with alkaline solutions of tin, e.g. with solutions of sodium or potassium stannate. The absorption of the alkaline solutions may be assisted by additions of swelling agents for the cellulose derivatives, particularly thiocyanates of alkali metals or ammonium. The treated materials show an increased resistance to hot treatments, such as ironing, and exhibit affinity for a wide range of colouring matters. In examples (1) a cellulose acetate fabric is immersed for an hour at 25‹ C. in a solution containing sodium stannate and sodium thiocyanate, the fabric is then soaped, washed and dried or otherwise treated as desired; it may be dyed with direct cotton dyes, e.g. sodium-p-sulphobenzeneazobenzeneazo-6-benzoylamino - 1 - naphthol - 3 - sulphonic acid (red shades), with anthraquinone vat dyes from a hydrosulphite vat, e.g. Caledon jade green, Indanthrone red violet RRK, or Algol Scarlet G, with indigo or other indigoid vat dyes, with mordant dyes, e.g. alizarin, with natural lyes, e.g. Hematine or Persian berries" with basic dyes, e.g. Rhodamine B, or with insoluble colours for cellulose acetate, e.g. p-nitrobenzeneazodiphenylamine and (2) a cellulose acetate fabric is impregnated with a solution of sodium stannate, rolled up, left for three hours, washed in water, treated with disodium hydrogen phosphate solution, washed, soaped and dried; it may be dyed with the dyestuffs indicated in example 1. The process may be applied to mixed goods containing cellulose esters or ethers in association with other fabrics not deleteriously affected by alkaline solutions, e.g. with cotton or viscose silk.

Abstract: 1,267,721. Transistor pulse generating circuits. HUGHES AIRCRAFT CO. 10 June, 1969 [16 July, 1968], No. 29354/69. Heading H3T. [Also in Division H2] A pulse generating circuit comprises a switching device (such as transistor 20) in series with the primary 12 of a transformer 10 across a supply 18, the switching device 20 being turned on to supply energy to the core of transformer 10 so that a pulse is generated in secondary windings 14 when the switching device 20 is turned off, the secondary windings being divided into sections 38, 40, 42 so as to minimize self-capacitance, each pair of sections being separated by a diode 48, 50. Fig. 1 shows a circuit for charging a pulse forming network 54 which may be discharged into a laser pump flash tube under control of a switch 57. Each pulse is initiated by a pulse OSC which sets a bi-stable circuit 36 which, in turn, turns on transistor 20, initiating a build up of current in primary 12. When the emitter voltage of transistor 20 reaches a predetermined level, a differential amplifier 26 provides an output which resets the bistable circuit 36, turning off transistor 20 so that the voltage induced in the secondary windings 38, 40, 42 becomes rectified by diodes 46 ... 52 so as to charge the pulse forming network 54. In Fig. 2 (not shown) the primary 12 is divided into sections each separated by a diode. Another figure shows a DC-DC converter in which the centre-tapped primary 180 of transformer 182 is energized by transistors 176, 178 alternately, so that a higher voltage DC output is provided at 232 after rectification of the secondary voltages by diodes 224 ... 240.
