Abstract: 128,800. Smith & Sons, S., and Dorer, P. O. Aug. 26, 1918. Speed - indicator transmission mechanism.-In a bevel-gear suitable for speedometers &c. for motor vehicles, the teeth of the large bevel-wheel A are formed by making radial incisions A<3>, Fig. 4, in a thin metal plate and bending back the radial edges of these incisions as at A<4>, Fig. 5, to form teeth or in place of radial cuts, pieces may be removed from the plate to form radial slots, the edges of which are bent back to form teeth. The plate may be formed as a dished annulus and bolted to a disk Y on the shaft X. The pinion B engaging the wheel A is preferably formed with a conical plain portion B<2> to engage the plain part A<8> of the wheel A, and may be kept in contact therewith, so that the teeth of the pins are in proper relation, by a spring. The shaft C of the pinion is carried by an arm E mounted to rock upon a rod F and prevented from longitudinal movement by a clamp G on the rod. By means of a spring H, the arm is controlled so as to press the pinion against the hand-wheel.

Title: Process for effecting chemical reactions in the interior of compressors
IPC: C01C1/04
Filed: 1923-05-30
Abstract: 217,747. Brutzkus, M. May 30, 1923. Ammonia; sulphur trioxide; sodium bicarbonate.-Chemical reactions are carried out in the interior of a compressor in such a way that the pressure, temperature', and concentrations, or the first two of these factors, are continuously varied from outside in the opposite sense to the variations caused by the desired reaction. For example, an exothermic reaction involving reduction in the number of molecules, such as the synthesis of ammonia, is carried out during the compression stroke and the mixture is continuously cooled either by externally cooling the cylinder or by injecting into it a stream of cooled gases at high pressure. Suitable apparatus comprises a compressor 1 driven by a pulley 5 and having inlet valves 2, 4 and an exhaust valve 3 all operated in known manner by a cam-shaft. On the downstroke of the piston 7 a mixture of nitrogen and hydrogen in stoichiometric proportions is drawn from the vessel 6 through the valve 2, the mixture being originally at such a temperature and pressure that when the piston has compressed it during two-thirds of its upstroke it has attained a pressure of 50 atm. and a temperature above 900‹ C. A further quantity of cooled mixture at a pressure of 80 atm. is then injected through the valve 4 in a continuous stream until the completion of the upstroke. The valve 3 is then opened and the gases exhausted to the washer 8, the residual gases being returned to the vessel 6 by way of the pipe 11. Alternatively, by opening valve 14 and closing valve 13 the whole reaction product can be returned to the vessel 6 to increase the pressure and temperature therein. An expansion cylinder may be inserted betwen the compressor 1 and the washer 8. Reactions of the same general type to which the process is stated to be applicable' are the oxidation of sulphur dioxide and the reaction between carbon dioxide and an ammoniacal solution of salt. Specification 155,776 is referred to.

Filed: 1941-11-07
Abstract: 578,006. Valves opened by explosions. ASIATIC PETROLEUM CO., Ltd., LUBBOCK, T., GOLLIN, G. J., LINDSAY, A., POOLE, H. J., and CROW, A. D. Nov. 7, 1941, Nos. 14399/41 and 15325/42. [Class 135] A valve 4 is opened by an explosive cartridge 1, and is locked in the open position by the engagement of detents 16 behind a shoulder 19, so that, for example, high-pressure gas from a storage cylinder connected at 6 may be passed to an outlet 7 for impelling combustion ingredients to nozzles in a combustion chamber of jet propulsion apparatus. The detents 16 may be forced outwards by the impact of a hammer 15 carried by the valve, on soft material 13. The detents may be retained in the unlocking position by a sleeve 20, which is forced beyond the detents, as the valve opens, by a skirt 17 secured to the valve. The explosion acts on a piston 3, which is connected to the valve and opens a vent 11 for the gases. Leakage past the valve, when closed, is prevented by a shearing-disc 12, for example of aluminium, which is ruptured by the valve. In a modification the detents are spring-actuated.
