Title: Improvements in or relating to electric cable systems
IPC: H02G15/26
Filed: 1933-12-02
Abstract: 419,592. Fluid-actuated valves. SOC. ITALIANA PIRELLI, 21, Via Fabio Filzi, Milan, Italy. Dec. 2, 1933, No. 25490/34. Divided out of and addition to 417,631, under which a Specification was laid open to inspection under Sect. 91 of the Acts, June 4, 1934. [Class 135.] In an oil-filled cable system of the kind described in the parent Specification employing a feeding reservoir, a pressure reservoir and a regulating device, comprising a valve and a flexible member adapted to operate the valve, for controlling the flow of oil from the feeding reservoir to the pressure reservoir and vice versa, the flexible member is now adjustably biassed towards the valve by a spring so that the pressure difference necessary to open the valve for the passage of oil from the feeding reservoir to the pressure reservoir may be rendered independent of the pressure difference required to open the valve for the flow of oil in the opposite direction. In the construction shown, a regulating device comprises a casing 6 divided into chambers 7-9 by partitions 10, 12, the chambers 7, 9 being connected together and to a feeding reservoir by pipes 15, 16, whilst a pipe 17 connects the chamber 8 to the cable and pressure reservoir. The partition 10, which is formed as a bellows is biassed by an adjustable spring 18 towards a spring-loaded valve 13 provided in the partition 12.

Title: Improvements relating to boiler feed water regulators
IPC: F22D5/12
Filed: 1938-09-01
Abstract: 518,773. Float valves. HOPKINSONS, Ltd., and BROWN, R. L. Sept. 1, 1938, No. 25577. [Class 135] A boiler feedwater regulator comprises a ball or closed float within the boiler operating an external valve c of double beat or balanced type in a casing d, the spindle e to which the float is secured and by which the valve is actuated passing through a glandless stuffing box in a sleeve-like extension g of the valve casing, which projects through the boiler shell b and serves as the connection to it. Normally with inter inlet pressure exceeding steam pressure a collar p on spindle e at the casing end bears on a washer q. A loose collar r and washer s may however be provided at the other end to prevent steam leakage to the valve chamber. The valve may be manually operated by a lever h on a spindle i co-axial with spindle e and carrying a bifurcated arm which embraces a pin k on a link o operating the valve.

Title: Improvements relating to the dynamic braking of induction motors
IPC: H02P3/24
Filed: 1947-09-19
Abstract: 637,129. Control of A.C. motors. EVANS, O. T., GHALIB, S. A., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Sept. 19, 1947, No. 25621. [Class 38 (iii)] In a dynamic braking system for induction motors a load resistor is automatically adjusted in accordance with motor speed, the adjustment being responsive to two signals, one proportional to motor speed and the other proportional to the displacement of the load resistor adjusting means. An induction type tachometer generator G is driven by a winder motor M and is of the type having two stator.coils and a copper tube rotor, one coil being fed from an A.C. source, thus inducing a voltage in the other coil which is of the supply frequency and of magnitude proportional to the motor speed and to the magnitude of the excitation. A device I, such as a variable inductor of the induction regulator type, potential divider or the like, is adjusted by a servomotor SM which operates the adjusting means for the load resistor R. The output voltage of the device I is of the same frequency as the output of the member G and is proportional to the setting of the load resistor R. The two signals are combined in a phasediscriminating amplifier A, the output of which, after amplification in a power amplifier P, is arranged to operate the servomotor. The load resistor is thus set to the correct value at any speed and for a constant D.C. excitation, during braking, torque will be maintained constant down to a speed of, say, 5 per cent full speed. A manual control may vary the braking torque by alteration of the D.C. excitation of the motor or, by controlling the magnitude of the signal proportional to motor speed. The load resistor may also be used for acceleration control during winding, the control being either manual or automatic. Specifications 632,831, 634,815 and 637,128 are referred to.
Patent GB-1393808-A (GB)
Title: Suspension struts
IPC: B60G13/14
Filed: 1972-06-01
Abstract: 1393808 Valves; self-pumping self-levelling suspension units F M ALLINQUANT and J G ALLINQUANT 1 June 1972 [8 June 1971 21 Feb 1972 16 May 1972] 25672/72 Headings F2S and F2V A self-pumping self-levelling suspension unit for a vehicle comprises a gas-containing liquid suspension chamber 74, 59, 58 which acts on the larger area face of a piston 14, and a gascontaining liquid reservoir chamber 53, 51, 50 which acts on the smaller area face of the piston, oscillations of the piston when the unit is extended beyond a certain length pumping liquid from the suspension chamber 74 to the reservoir 53 to contract the unit until a return line 46 opens and allows flow from the reservoir 53 back into the suspension chamber 59. The gas pressures in the chambers 58 and 50 are chosen such that, when the vehicle is stationary, even with the maximum load the unit will be longer than the preferred length, i.e. the piston is below the position shown. As the vehicle moves off, upward movements of the piston cause an increase in pressure in the chamber 74 and a reduction in pressure in the annular chamber 53 (which is supplied from the chamber 51 through a small orifice 52). A valve element 72 therefore opens and some liquid passes from the suspension chamber 74 to the chamber 53. On downward movements of the piston the liquid flows from the chamber 53 to the chamber 51 through a non-return valve 54. Alternating movements of the piston thus produce a transfer of liquid from the suspension chamber to the resevoir chamber and the piston ascends until it rises above the line 46 which places the suspension and reservoir chambers in communication. From there on the unit is maintained at this level. Damping valves.-Oscillations of the piston about the mean position are damped by valves either between the suspension chambers 74 and 59 (Fig. 7) and/or between the reservoir chambers 53 and 51 (Fig. 8, not shown). The heavier the load the higher the damping afforded by the valves. In Fig. 7, Belleville washers 204a urge a valve piston 203 into the position shown, where grooves 211 co-operate fully with ports 202 in the cylinder wall to provide a completely open path between the chambers 74 and 59. As the pressure in chamber 74 increases, the valve piston progressively covers the ports 202, to restrict the flow. In Fig. 8 (not shown) a spring-biased needle valve (310) upstream of a non-return ball valve (302a) is controlled by the pressure in the chamber 51 which is fed back to a control piston (311).

As shown diagrammatically in Fig. 1, a three-way cock 4 is employed between the engine 2 and the carburetter 3, by means of which the engine cylinder can be shut off from the carburetter and put into communication with a chamber 9, the lower part of which is connected by a pipe 5 to the suction pipe 18 of the centrifugal or other pump 1. During priming the pump discharge pipe 19 is closed by a valve 20, which may be a hand-operated valve, or a check valve. A valve 21, which may be spring- pressed or hand-operated, indicates when the pipe 19 is full of liquid. As shown in Fig. 5, the three-way cock may control an auxiliary supply of petrol from a chamber 15 during priming. During normal running, the cock 13 puts the upper part of the chamber 15 into communication with the atmosphere and the lower part into communication with the float chamber of the main carburetter. When the plug 13 is turned to effect priming it simultaneously cuts off the chamber 15 from the atmosphere and from the carburetter, and puts it into communication with a jet 14 in the plug cock.
