Filed: 1941-04-07
Abstract: 574,166. Blasting detonators. DU PONT DE NEMOURS & CO., E. I. April 7, 1941, No. 4599. Convention date, April 6, 1940. [Classes 9 (i) and 9(ii)] A blasting detonator is provided with a primary detonating composition, e.g. lead azide or fulminate, the sensitiveness of which to shock has been reduced by blending it with a small percentage of a water insoluble metal soap, such as calcium, aluminium or magnesium stearate or aluminium oleate. The base charge which may be of tetryl may also be blended with a low percentage of calcium stearate so that it can be worked easily. The percentage of metal soap ranges from 0.5 per cent to 5 per cent. In the detonator, shown in Fig. 3, the base charge 2 is contained in a metal case 1 and the blended detonating mixture 3 is superposed, and a firing charge 4 superposed on this. The charge 4 may be fired by a slow fuze, an electric current or, for a delay action, by a filament 9 through a delay carrier 13 perforated at 14 to receive the slow-burning powder. In a modification, Fig. 4, the blended detonating mixture 3 is enclosed in a cavity in the base charge 2 which is also blended with water-insoluble metallic soap.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1927-02-18
Abstract: 292,199. Electrolux, Ltd., and Cracknell, R. J. Feb. 18, 1927. Absorption machines and processes; refrigerator, domestic.- Continuous-cycle apparatus containing a pressure-equalizing inert gas, and provided with means for exchanging heat between the cold gas mixture and both the inert gas and condensad refrigerant, as set forth in Specification 290,207, comprises a coaxial arrangement of the evaporator, gas heat exchanger and absorber in a common cylindrical member. In the form shown, a heated generator 1 is connected through a rectifier 3 with a watercooled condenser 4, from which the condensed refrigerant flows into a chamber 5. From this chamber it flows through a jacket 6 around the rectifier and by a pipe 7 and a coil 13 to the upper part of the evaporator 8. The evaporator is arranged within a cylindrical casing 12 containing the absorber 10 at its lower end and the gas heatexchanger between these parts. The evaporator and absorber contain spaced perforated plates and the inert gas rises from the top oi the absorber to the top of the evaporator through a pipe 15, while the inert gas and refrigerant vapour mixture flow downwards around the coil 13 to cool it and then through a pipe 16 to the bottom of the absorber. A lip 21 on the pipe 15 or on the lowest evaporator tray or on the wall 12 deflects any unevaporated refrigerant on to the surface of the coil 18. A heat exchanger 18 for liquid, comprising a coiled part of the weak liquor pipe 17, is arranged below the absorber and within the casing 12, and the end of the coil preferably passes through the pipe 16. Similarly the end of coil 13 passes through pipe 15. The evaporator and heat exchanger may be arranged in the upper part of a cabinet 22, and collecting trays 23, 24 for moisture may be provided. A vent pipe 25 extends from the gas exchanger spaceto the condenser outlet.

Title: Improvements in and relating to yarn and like winding methods and machines
IPC: B65H54/36
Filed: 1946-02-15
Abstract: 615,234. Winding yarn &c. TRIGGS, W. W. (Kidde & Co., Inc., W.). Feb. 15, 1946, No. 4774. [Class 120(ii)] A yarn &c. winding machine comprises a furnishing device for positively pulling the yarn &c. from supply at a rate substantially proportional to the winding speed and delivering it under substantially uniform tension to the rotary package, and also comprises a member continuously touching the package and pressing on the yarn delivered by the furnishing device, the pressure member being positively retracted at a speed determined by the growth of the package size, thereby allowing the package to grow, at will, under uniform pressure and with substantially uniform tension in the thread therein. The cop tube, clamped to the spindle 14, is driven through a belt 21, tightened by an idler pulley 22, the spindle 14, through a train of reduction gears in the gear box 28, driving the cam shaft 18, the cam 19 of which reciprocates the thread guide 33 through a rod 36. The guide 33 is kept away from the package by a plate 32 which bears thereon. The back plate 30, carrying the thread guide 33, is positively moved away from the spindle 14 by a rack 81 operated by a gear 80 through a gear train of high reduction ratio of 937,500 revs. of the spindle to one rev. of the gear 80. This reduction train is driven from the cam shaft 18 and comprises gears 49, 60, 63, a pawl 64, a braked ratchet disc 67, two gears 73, 74, differing by one tooth, the gear 73 being fixed to the hollow shaft 52, with which gears a pinion 72 rotating with a disc 70 meshes to advance the gear 74 slowly. This gear is pinned to a disc 71 carrying a pinion 75 which meshes with gears 76, 77 differing by one tooth, the gear 76 also being fixed to the hollow shaft 52. The gear 77 drives a friction collar 79 and the pinion 80 by which the rack 81 is moved. A shaft 55 may be turned by a collar 85 over a graduated disc 88 to turn a shield 65 to vary the number of ratchet teeth in the disc 67 advanced by each revolution of the pawl 64. The train of gears allows the back plate 30 to be moved by hand towards the spindle 14 at the beginning of a fresh wind. The thread from supply is fed to the package through two rubber-coated conical rollers 98, 97, the roller 98 being driven from the shaft 92 rotated by a belt from the pulley 94 on the spindle shaft 14. The guide eye 121 on the bar 120 is moved by an arm 101 connected to a sector 108 to lead the yarn towards the bases of the feeding conical rollers 97, 98, to give a greater feed rate, as the package grows in diameter. The bar 120 is connected by chains to the sectors 108, 109, the sector 109 being spring-biassed by a spiral spring 111. As the rack moves inwardly and the package attains a predetermined size, a rod 107 drops upon the shoulder 106 on a plate 105 to bring into action a known form of automatic stop motion.

Abstract: 1,115,081. Valves. BRITISH ERMETO CORPORATION Ltd. 4 Feb., 1966 [4 Feb., 1965], No. 4909/65. Heading F2V. Pressure in an outlet 16 is maintained constant by a valve 14 having lands 14a, 14b controlling a vent 17a and an inlet 15b, respectively, the outlet pressure acting on the underside of the land 14b through a passage 14c in opposition to the fluid load applied by inlet pressure to the valve through a piston 12 and an adjustable lever 18. If pressure in the outlet rises the valve is lifted to open the vent 17a while a fall in pressure causes the fluid load to depress the valve and open the inlet 15b. The position of the fulcrum of the lever 18 may be adjusted by a threaded spindle and determines the ratio of inlet and outlet pressures. A number of valves set to different outlet pressures may be used to supply rams for applying test loads to aircraft wings. Leakage past the piston 12 and the valve 14 is collected by the vent 17.
