IPC: F04B39/08
Abstract: 106,717. Huwiler, A., and Maggi, H. July 25, 1916. Compressed-air engines. -An interconvertible air compressor and motor is constructed with horizontal cylinders on one side only of the crank shaft so that it can be mounted by the side of the engine of a motorcar. The apparatus comprises a pair of double-acting cylinders I, II which serve as the motor cylinders and the first stage of the compressor, a pair of single-acting cylinders II, IV which serve merely as the second stage of the compressor, and a rotary distributing valve v which controls the double-acting cylinders. The ports b, b<1> of the valve communicate with the atmosphere, while the ports d serve as pump delivery port and motor admission ports. When the apparatus acts as a pump. the air passes from the cylinders I, III by way of passages d, f, g in the valve to a chamber h; thence it passes by way of the passage i, valve k, and passage m to the cylinders II, IV, and after further compression is delivered by way of the valve o, passage p, valve q, passage r, filtering chamber s, and passage t to the reservoir. When the apparatus serves as a motor, the valve k closes the passage m and opens the passage n to the passage i, thus permitting air from the pipe t to flow into the chamber h and thence through the ports d in the valve to the cylinders I and III. The valve w opens the cylinders TT and IV to the atmosphere when the apparatus works as a motor.

Title: Improvements in or relating to automatically operated variable pitch air propellers
IPC: B64C11/42
Filed: 1937-05-18
Abstract: 501,127. Screw propellers. SIEMENS APPARATE UND MASCHINEN GES. May 18, 1937, No. 10950. Convention date, July 9, 1936. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 18, 1937.] [Class 114] An automatic hydraulically operated pitchadjusting gear wherein a motor and centrifugally actuated regulating valve are mounted in the propeller hub is set for any one of a number of constant speeds by varying the pressure of the hydraulic medium and varying the tension of the spring of the regulating valve thereby. In one form, the blades of the propeller are adjusted through gearing 11, the initial wheel of which is on the shaft of one element of the gear motor 10. This motor is in a pipe connection with a line 1 from the main lubricating system of the driving engine. The complete piping includes a regulating valve 6 which is automatic and a throttle valve 2, which is hand operated. The regulating valve 6 which is constituted by a piston member 7 under spring restraint 8 and so disposed that during rotation of the propeller increase in centrifugal force operates to tend to move the piston against the spring pressure. When these two forces are balanced, the piston is in the position shown, wherein the pipes 9 and 14 are shut off from the oil motor 10 and the pitch remains fixed. On change of speed, the piston7 moves and one or other of the ports is opened to the delivery side and the other exhaust with the result that operation of the motor 10 gives alteration of pitch. The speed at which balancing is effected between the piston 7 and the spring 8 is adjustable by altering the position of cock 2 and thus the pressure in the pipe-line, a branch from which leads to a cylinder, the piston 34 therein acting through an arm and cam 30 upon the spring. In a modification, a supplementary piston 22, with spring restraint 24 but open to oil pressure by pipe 5, is connected by link 25 with an adjusting cam which moves over a plate on the main .spring 8 to provide regulation. This may be extended to carry a weight 26 so that a further regulation is effected under centrifugal force in relation to the speed of the rotation.

Abstract: 285,279. Automatic Telephone Manufacturing Co., Ltd., and Tench, F. Nov. 5, 1926. Drawings to Specification. Automatic exchange systems.-An impulse sender, e.g. in a register-controller, comprises a counting switch which stops in the position in which it terminates each digit, but takes an idle step just before starting the next one. The stopping potential can thus be connected to the appropriate points in the bank throughout the sending operation. The final digit is terminated by a different potential (e.g. battery instead of ground) which initiates the release of the register-controller. The switch has two counting wipers (the second becoming operative when the first leaves its bank) and a single homing wiper, and if the sender is released while the first wiper is on its bank, the second is not connected up. The system described is identical with that described in Specification 275,343.
