Title: Improvements in washing machines
IPC: D06F17/12
Filed: 1931-02-26
Abstract: 364,409. Washing-machines; washing-boilers. FABER, G., 27, Gartenstrasse, Botnang, Stuttgart, Germany. Feb. 26, 1931, No. 6087. Convention date, Sept. 1, 1930. [Class 138 (ii).] A washing-machine or boiler comprises a central vessel a which contains the washing &c. and is housed in a jacket c which is open to the atmosphere at the top. The bottom of the central vessel communicates with the jacket through apertures u. The removable cover e of the central vessel carries a casing f, g wherein a motor h and fan casing i are resiliently supported by springs n and a rubber ring k which rests on an internal flange m. The casings f, i are provided with apertures q, p respectively. An adjustable valve r controls the degree of vacuum in the vessel and a fabric filter plate o prevents suds &c. from rising into the motor and fan casings. The suction of the fan draws liquid from the jacket into the central vessel until the liquid seal is broken whereupon air passes into the central vessel and reduces the vacuum so that the liquid seal is re-established and an oscillation of the liquid and materials in the central vessel produced.

Title: Improved control system for power systems
IPC: B63H21/22
Filed: 1962-02-21
Abstract: 976,104. Reverse gear control. T. HINDMARCH. Feb. 8, 1963 [Feb. 21, 1962], No. 6801/62. Heading F2D. [Also in Division G1] In a reverse gear control for a ship, rail-car or rolling mill wherein hydraulically operated forward and reverse clutches C2, C1 are controlled by a selector valve MCV in response to signals from a manual control CH which also controls engine speed, switches f, g, h, i controlled by input and output speed responsive devices SS1, SS2 prevents establishment of a ratio if the gear input or output speed exceeds a predetermined value and triple switches a, b, c; j, k, I respectively responsive to engagement of the clutches C1, C2 prevent engagement of one clutch while the other is engaged and prevent increase of engine speed until one of the clutches is fully engaged. Ratio shift may be facilitated by providing a brake B on the output shaft which brake is engaged when the selector valve MCV is in its neutral position, or by providing switches d, e which hold the clutch for the previous ratio engaged, after the manual control has been moved to the neutral position, until the output speed falls below a predetermined value. Movement of the manual control CH from the netrual position shown to the ahead position closes a switch n and completes a circuit through switches h, f, a to a solenoid valve SV1 which supplies pressure liquid to a servomoter VO1 that operates the selector control valve MCV. When the forward clutch C2 is fully engaged a pressure sensitive element PS2 changes switches j, k, l. The switch j completes a holding circuit to the solenoid valve SV1 which bypasses the switches f, h so that when the input and output speeds increase and the switches f, h open the solenoid valve SV1 remains energized. The opened switch k ensures that the reverse solenoid valve SV2 cannot be energized whilst the forward clutch C2 is engaged and the switch h completes a circuit in the engine speed control SC that permits increase of engine speed. On movement of the manual control CH from the ahead position to the astern position the energization of reverse solenoid valve SV2 and engagement of the reverse clutch C1 is delayed until the forward clutch C2 is disengaged and the switch K is closed and until the input and output speeds fall below a predetermined speed to close switches g, i. An engine speed follow-up control, Fig. 2 (not shown) is unbalanced and returns engine speed to idling when both switches c, h are open during ratio shift. An emergency control which overrides the delay mechanism may be provided.

Abstract: 398,528. Rectifying alternating current. AKT.-G'ES. BROWN, BOVERI, ET CIE, Baden, Switzerland. March 8, 1932, No. 6918. Convention date, March 9, 1931. [Class 38 (ii).] In a mercury-arc rectifier system in which grids 4 associated with the anodes 3 are maintained at,a potential positive with respect to the anodes during the conducting periods thereof and negative with respect to the anodes during the non-conducting periods, provision is made whereby in the event of overload or back ignition the grids are disconnected from their normal source of voltage and either left isolated or connected to an alternative source of voltage which maintains them negative with respect to the cathode 6. The grid energization under normal conditions is effected by a transformer 12 providing a voltage in phase with and of greater amplitude than the anode voltage, the transformer voltage having imposed thereon a D.C. biassing voltage supplied by a battery 13. This circuit is adapted to be broken under overload or back ignition conditions by a relay-operated switch 10 controlled by a current transformer 5 associated with the primary circuit of the main transformer 1. The grids may, under these conditions, be brought to a potential negative with respect to the cathode by the switching in of a battery 16 by closure of a switch 14 operating in accordance with current in a shunt 8 in the load circuit 7.

Filed: 1923-03-10
Abstract: 218,706. Peter, B. H., Winter, H. J., and Westinghouse Brake & Saxby Signal Co., Ltd. March 10, 1923. Fluid-pressure brakes controlled either electrically or by variations in train pipe pressure. The complete release of the brakes by electric means is prevented by interposing a loaded check valve in the passage leading from the brake cylinder to atmosphere. The braking system shown in Fig. 1 comprises a driver's valve 3, triple valve 1, auxiliary reservoir, and brake cylinder 2, and an electrically-controlled release valve 7 controlling the exhaust from the brake cylinder through the pipe 29 to an exhaust port 25. When the valve winding 9, Fig. 2, is energized, the rod 20 is raised to open the exhaust valve 20 against its spring 22, but when the brake cylinder pressure has fallen to a predetermined value, the check valve 26 closes under the aotion of the spring 27 to prevent further release, complete release being effected pneumatically. The winding 9 is energized by tilting the handle 19 of the driver's valve to close the contacts 18 by means of the pivoted arm 30, this action being permitted only when the handle is in the " lap " position.
