Title: Torque amplifier
IPC: B62D5/14
Filed: 1957-03-22
Abstract: 843,122. Vehicle power steering. TEVES, H., TEVES, E. A., and TAUSEND, M., [trading as TEVES MASCHINEN-UND ARMATURENFABR'IK KOMM-GES., A.]. March 22, 1957 [May 18, 1956], No. 9518/57. Class 79(5). [Also in Group XXIX] In a torque amplifier for a motor vehicle steering system comprising a cylindrical casing 1 Fig 1 sub-divided, by walls 2, 3 into two. chambers 5, 6 through which pressure medium continuously flows, valves influencing the flow are mounted in the vanes 12, 13 of the drive output shaft 4 and are actuated selectively by cams on an input shaft 14, the return movement of the valves being limited by stops so that reaction pressures are not exerted when the valves are open. Pressure medium entering the chamber 5 at port 1 flows to an outlet port 8 and is then fed through a pipe 9 into the chamber 6 at entrance port 10 and leaves at an outlet port 11 so that the pressure medium flows continuously and successively through the two chambers. In one example the output shaft 4 is sealed between the walls 2, 3 and carries valves 16, 17 mounted in fluid tight radial guides 12, 13. The valves 16, 17 are actuated radially to interrupt the flow between their ends and the wall of the casing 1 by rollers 15 on a cam 14 which is integral with the input driving shaft. Leaf springs 18, 19 normally centralise the cam 14 and bevelled faces 23, 24 on the ends of the valves 16, 17 provide hydraulic feel. Projections 21, 22 of the valves 16, 17 prevent retraction of the valves so that reaction forces on the actuating cam 14 are not exerted. In a modification, vanes 31, 32 Fig. 3 'on the drive output shaft engage the walls of the chamber in fluid tight fashion and have apertures 33, 34 for the passage of fluid, the flow being controlled by valves 37, 38 actuated by cam arms 35, 36 on the controlling member 14. The valves are arranged with fluid seals in bores 39, 40 and are yieldably located by springs so that adjustable screw nuts 43, 44 on the valves engage cover plates 41, 42 on the vanes 31, 32 to limit the return movement of the valves to prevent the exertion of reaction pressures. Bolts 45 on the cam arms 35, 36 vary the free play of the controlling member 14. In embodiments the torque amplifier may be inserted between two parts of a connecting rod from the steering column or may be between the rocker shaft and the drop arm.

Title: Improvements in or relating to remote control systems
IPC: G05D3/18
Filed: 1947-04-11
Abstract: 641,950. Control of D.C. motors. FOSTER TRANSFORMERS & SWITCHGEAR, Ltd., and JENNINGS, R. E. April 11, 1947, No. 9693. [Class 38(iii)] [Also in Group XXXVIII] In a follow-up system for remote control of lighting or other circuits, Fig. 3 (not shown) the error voltage derived differentially from a transmitter potentiometer and motor driven potentiometer controlling the lighting &c. circuits, is fed to the primary winding of a transformer T, Fig. 1, and the follow-up motor A.R. has two field windings 1, 2 supplied from an A.C. source 3 through respective thyratrons A, B biassed by a voltage having a mains frequency component lagging the anode voltage and a super-imposed negative D.C. component, the biassing voltage being fed to the thyratrons through the centre tap of the secondary of the transformer T. The transformer T feeds the error voltage to the triode grids in push-pull, and the grids are biassed over a network R1C1, R2C2, D1, fed from a mains connected transformer 4 by a mains frequency component lagging the anode voltage by 90 degrees on which a D.C. negative bias is superposed. In the absence of any error voltage both triodes fire simultaneously late in each positive half-cycle to produce balanced currents in the motor fields. The error signal derived as in Fig. 3 (not shown) is of mains frequency and in phase or antiphase relative to the anode voltage, and causes one triode to conduct more than the other thus causing rotation of the motor in a direction dependent on the phase-sense of the error signal. In a modification, Fig. 2 (not shown) the motor has a separately excited D.C. field and the two triodes which are connected in parallel reverse cause armature current to flow in one direction or the other according to the phase sense of the error voltage.

Title: Improvements relating to centrifugal pumps
Inventor: ASHWORTH NORMAN IVES
IPC: F04D29/42
Filed: 1957-03-26
Abstract: 840,671. Centrifugal pumps. ASHWORTH, N. I. Nov. 14, 1957 [March 26, 1957], No. 9799/57. Class 110 (1). In a centrifugal pump of the kind in which the shaft is vertical and enters the top of the pump casing through a sealing-passage which.permits fluid from the pump casing to escape to discharge between the shaft and the wall of the sealing passage and seal the sealing passage against intake of air and so that the mixture of liquid and abrasive being pumped does not reach a shaft bearing, means are provided for ejecting the mixture from the upper end of the sealing- passage by means of a member rotating with the impeller shaft and creating a stirring or centrifugal action, or both. The centrifugal pump shown draws in a mixture of abrasive and water from a sump 13 through a conduit 14. The driving-shaft is not provided with a packing gland, and liquid passing up the annular space between the shaft and a sleeve 8 and then down between the sleeve 8 and an annular hood 11 carried by the shaft is returned to the sump by way of a passage 12. Liquid is contained in the passage 12 up to the sump liquid level A, thereby preventing air from entering the pump by way of the annular space between the shaft and the sleeve 8. The boss 17 of the impeller passes freely through an opening in the pump casing, the clearance space around the boss communicating only with the space between the shaft and the sleeve 8. Since there is no packing gland or bearing to hold abrasive against the shaft, the shaft is not subjected to a grinding action. The pump casing and impeller may be provided with abrasive-resistant linings. According to the Provisional Specification, the shaft is provided with a thrower disc having a depending flange, to deflect escaping abrasive mixture back to the sump.

Title: An improved coupling device
IPC: F16G11/00
Filed: 1929-10-24
Abstract: 342,678. Wire &c. couplings. OSBORNE, H. F., 23, Julius Road, Bishopston, Bristol. Oct. 24, 1929, No. 9889. [Class 99 (i).] A member 2 is centrally bored at one end to receive a plug member 4 which is locked therein by a series of balls 9 adapted to be forced into a groove 10 in the plug 4 by a sleeve 11, the latter also being locked in position by a series of balls 8 which engage either a groove 12 therein or a groove 25 in a spring-pressed piston 23 located within the bore 3 of the member 2. The inner end of the plug 4 is formed with a projection 5 which is adapted to abut against the piston 23 and compress its spring 24 when the parts are coupled, and the sleeve is held in a position to maintain the balls 8, 9 in the grooves 26, 10 by a spring 15. The sleeve is also formed with a groove 13 to receive the balls 9 when the parts are to be uncoupled. With the parts locked together as shown in Fig. 1, movement of the sleeve to the left will cause the balls 8 to move into the groove 12 under the action of the spring 24, whereupon the sleeve will be held in this position to permit the balls 9 to enter the groove 13 and release the plug 4. Conversely when the plug is forced into the bore 3 the projection 5 will move the piston and allow the balls 8 to enter the groove 26, whereupon the spring 15 will urge the sleeve 11 to the right and compel the engagement of the balls 9 with the groove 10. Accidental unlocking of the coupling may be prevented by providing the sleeve with a ring 4<1> formed with recesses 13<1> which are adapted to receive balls 9<1>, normally engaging recesses 10<1> in the end of the member 2, upon rotation of the sleeve to permit longitudinal movement thereof. In a modification, Fig. 2, the sleeve 11 is locked in position by balls 45 which engage either a series of recesses 48 in the sleeve or grooves 44 formed in a plurality of spring-pressed pistons 42 which are located within bores or an annular groove 41 in the main member 27 and are formed with end pins which may be engaged by a flanged or enlarged end of the plug member 29. The plug is preferably provided with a hollow nose 37 for the reception of a line &c. The invention is particularly applicable to wires, ropes, cables, &c. for connecting, for example, a trailer to another vehicle; it may also be used on rowlocks or to replace hooks on cranes.
