Title: Improvements in or relating to nozzles for atomising liquids
Inventor: KURATA FRED
IPC: B05B1/08
Filed: 1952-09-12
Abstract: 719,679. Spray-producers. KASK TECHNICAL CORPORATION. Sept. 12, 1952, No. 22942/52. Class 69 (3). [Also in Group XI] A valve stem 10, Fig. 1, is supported by a bow-spring 1, and its head 11 is adjustably forced against the outlet of a nozzle 5. The spring and valve device are arranged to form a resonant system producing a vibrating action of the valve head to atomize liquid fed to the nozzle. In Fig. 3 a spring 32 is compressed between a valve head 28 and a cap 26 and the head is forced against an outlet 23. A valve stem 27 slides through an apertured disc 36 and the spray passes through openings 34. In Fig. 4 a spring 68 is compressed between a member 66, screwed to a valve stem 60, and a nozzle wall, so that a valve head 63 is seated on an outlet 54. Alternatively, the valve head is seated on a nozzle outlet by a leaf spring or by a conical-helical spring housed within the nozzle body.

Title: Improvements in continuously regulable gears
IPC: F16H37/02
Filed: 1950-09-22
Abstract: 681,502. Variable-speed gear. PATENTVERWERTUNG W. REIMERS, GES. Sept. 22, 1950 [Oct. 6, 1949], No. 23311/50. Class 80 (ii). In a continuous regulable gear having a driving shaft 3 and an output shaft 5 and in which a regulable mechanical gear 1 having a driven shaft 4 between which and the output shaft 5 is disposed toothed wheel gearing 11, 12, 13, 14, with the interposition of disconnectable couplings 6, 16, the transmission ratio of the toothed-wheel gearing 11-14 is equal to the total range of regulation of the gear 1, and a further gear 7, 8, 9 is disposed between the output shaft 5 and the driving shaft 3, the further gear having a ratio equal to the lowest (or highest) ratio of the regulable gear 1, and having a coupling 10 for connecting or disconnecting the gear. The arrangement enables the range of the gear 1 to be extended without it being necessary to disconnect the drive between the shafts 3 and 5 while varying the ratio over any part of the range. The range may be extended to any desired limit by the addition of a sufficient number of toothed-wheel gear trains (such as 21-24) and associated gears between the shafts 3 and 5 (such as 17, 18, 19), as are necessary. In operation, the coupling 6 is initially engaged and the couplings 10 and 16 are disengaged. Assuming a step-down is desired between the shafts 3 and 5, the gear 1 is regulated so as to produce the lowest speed for shaft 4. The gear 7, 8, 9 which as shown comprises a chain 7, has a step-down ratio equal to the ratio 1: y between the (fixed) speed of shaft 3 and the lowest speed of shaft 4. The gear 9 of the chain gear 7, 8, 9 and the shaft 3 are thus rotating synchronously, and transmission may be diverted through the gear 7, 8, 9, by engaging the coupling 10 and disengaging the coupling 6. The gear 1 is now regulated to its highest ratio 1 : x. Since (according to the invention) the ratio of the gearing 11-14 is x : y, the gear 14 will be in synchronism with the shaft 5. The coupling 16 is now therefore engaged and the coupling 10 disengaged. The gear 1 may now be regulated to its ratio y (bringing the shaft 4 to its lowest speed). This results in an effective total ratio between the shafts 3 and 5 of 1 : y<SP>2</SP>. The addition of the gear 17-19 (which needs to have a step-down of 1:y<SP>2</SP>/x) and the gear 21-24 which has the same ratio x : y as the gear 11-14 increases the range to 1 : y<SP>3</SP>, and so on. If a step-up is required between the shaft 3 and 5 the various ratios are correspondingly reversed.

Abstract: 673,698. Ventilating aircraft. TRIGGS, W. W. (Garrett Corporation). Sept. 12, 1949, No. 23528/49. Class 137. [Also in Group XIII] From a source of air under pressure, e.g. the jet compressor 10 of an aircraft, the air is passed through a duct 13, heatexchangers 18, 20 and an expansion engine 21 to a distributer 14 in the cabin 15 or other compartment as shown by the full-line arrows 16, and part of the expanded air from the outlet 22 of the engine is recirculated by a compressor 25 back to the duct 13 as shown by the dotted arrows 27. The heat-exchanger 18 is cooled by ambient air drawn from the inlet 11 of the jet compressor by a turbine pump 33 driven through a clutch 35 and glaring 36 from the expansion engine 21, which also drives through a clutch 31a a two stage compressor 25 for the re-circulated air which acts as a coolant in the heat exchanger 20. The re-circulated air mingles with the inlet air in a pipe 26. A byepass 37 for directing uncooled air to the cabin is controlled by a valve 40 operated by a thermostat 42 in the cabin. The clutch 31a may be disconnected when the aircraft is on the ground so that all the power of the turbine 21 is available for driving the pump 33. The clutch 35 is disconnected when sufficient air pressure as available in the pipe 28. The cabin has an air outlet valve 44 as -described in Specification 655,601 [Group XXIX].

C., c/o Dunlop Rubber Co., Ltd., Fort Dunlop, Birmingham. Aug. 22, 1934, No. 24191. [Class 94 (i)] In a machine for spirally wrapping pneumatic tyres and other annular articles, the tyre is supported and driven from the inner periphery, and stabilizing means are provided to engage the article on or adjacent to the outer periphery. As shown, a motor 2 drives a pulley 4 on a shaft 5, from which gearing 24 transmits the drive to a supporting and driving roller 23, upon which the inner periphery of the tyre A rests. The wrapper 13 is spirally applied by a rotary carrier 12 driven by a belt 10 from a pulley 9 on the shaft 5. Adjacent the carrier, and on each side of the wrapping point are contoured rollers 25, 26, coacting with pairs of rollers 28, 29 to stabilize the tyre. A roller 31 is adapted to be brought to bear on the outer surface of the tyre to force it into engagement with the driving roller 23. The three rollers 25, 26, 31 are adapted to be brought into their operative positions simultaneously by a pedal and links 33. A bifurcated guide 38 may be added. The rollers may be made adjustable, e.g. by a nut and screw adjustment 37. The roller 23 may be tyred with sponge rubber. The apparatus may be adapted for unwrapping tyres by the provision of reversing means and of means for batching the wrapping material on the carrier.
