Title: Disc brake
Inventor: EATON MAURICE BARRY
IPC: F16D55/224
Filed: 1964-08-15
Abstract: 1,108,940. Disc brakes. GIRLING Ltd. 9 Aug., 1965 [15 Aug., 1964], No. 33407/64. Heading F2E. A disc brake, more particularly for a rail vehicle, comprises a housing 10 having an opening 11 (Fig. 3, not shown) which receives a peripheral portion of a disc (not shown), and which is floatingly supported from a fixed bracket 22 via an intermediate link 16 having a flexible mid-portion and rigid upper and lower portions which are pivoted to respective lugs 12, 13 and 19, 21 on the housing and bracket, respectively, the housing containing a fluidpressure actuator which applies a pad 59 to one face of the disc via a pair of levers 38, trunnion block 52 and rod 54, and by its reaction applies a pad 26, secured to a part 23 of the housing to the opposite face of the disc. A leaf spring (not shown) may be provided to centralize the housing with respect to the disc. The actuator is preferably pneumatic, as shown, but may be hydraulic. It comprises a diaphragm 31 and piston 32, the latter being connected by pin 37 to one end of the levers 38, which are mounted centrally on a trunnion block 45 and pivoted at their lower ends to the block 52. The block 45 is carried on studs 48 with play to allow it to float parallel to the plane of the disc, so that angular movement of the levers is accommodated at the expense of up-and-down movement of the pin 37. The latter is allowed for by mounting the piston 32 flexibly in a compressible bush 36 via a pin 33. Alternative manual operation of the brake is effected by a cable passed through a boss 43 and connected to the piston via a rod 41 slidable in a shackle 39 so that operation of the piston does not move the cable. The pad 59 is carried by a backing plate 58 which is supported from the housing by a link 74, and is also guided via a sleeve 56 in a bearing 57 in the housing. Rod 54 has a threaded connection with the sleeve 56 and is rotated automatically to take up pad wear by co-operation of a roller 63 carried by a pin 62 with a helical slot 64 (Fig. 11, not shown) in a collar 65 which is urged by a spring 69 so that ratchet teeth 68 on it engage corresponding teeth by a rotatable member 72 having a handle 73 for manual adjustment, the rotation of the collar during brake application causing slipping of the teeth when wear is excessive so that rod 54 is rotated on brake release.

Abstract: 824,244. Separating liquids by gravitation only. SILLEY, H. A. J., UNTHANK, D. G., and BRISTOW, L. Nov. 14, 1955 [Nov. 30, 1954], No. 34707 /54. Class 46. [Also in Group XXXV] Apparatus for separating liquids of different specific gravities comprises a closed container 10, 11 having an inlet 26 for the liquids to be separated, two outlets 18, 30 each for a different separated liquid constituent of the liquids, means, such as coaxial tubes 15, 16, 17 within the container connecting the inlet with the outlets and providing a passage through which the liquids flow with change of direction to separate into two constituent liquids, a valve 31 in one outlet 18 biased as by a spring 32, to oppose outflow of the constituent liquid, and a second valve 33 in the other outlet 30 and actuated by a double-acting liquid-operated motor 34, 35 supplied with liquid under pressure from the interior of the container. In its passage through the container, the liquid passes perforated baffles 24, 23 which split it into small streams to assist separation. Liquid is pumped into the container to maintain a pressure determined by the spring 32 of the outlet valve 33. The heavier liquid, e.g. water rises up the pipe 15 and is discharged past the valve 31 in the outlet 18, the pressure holding closed the valve 33 in the outlet 30 for the lighter liquid e.g. oil until movement of a pilot valve 38 opens a passage 40 and the upper part of the cylinder 35 to the container pressure whereupon the piston 34 moves downwards opening the valve 33 and compressing a spring 37 normal engaging the valve without pressure. As the valve opens the spring develops increasing pressure against it until the reduction of pressure through the escape of the oil allows the spring to close it again. Electrical contacts 46, 47, excited according to the position of the interface of the oil and water, actuate a solenoid 52 which adjusts the position of the valve 38. A further contact 48 may actuate an alarm

Title: Improvements in and relating to magnetic amplifiers
Inventor: WILLHEIM RAOUL
IPC: H03F9/04

Abstract: 794,427. Magnetic amplifiers. ULTRA ELECTRIC, Ltd., and WILLHEIM, R. Dec. 1, 1955 [Dec. 3, 1954], No. 35100/54. Class 40 (4). Three-limbed cores are used in half-wave or full-wave magnetic amplifiers, load windings being wound on the outer limbs of a core or cores and being connected to an A.C. supply to form two circuits operating in push-pull and supplying a load with a differential output, control windings also wound on the core or cores being such that voltages induced from the A.C. supply cancel out; the core or cores also carry bias windings. With a half-wave pushpull amplifier using a single three-limbed core the flux due to the A.C. windings is preferably made to converge on the centre limb while flux due to D.C. control windings circulates in the outer limbs and by-passes the centre limb. A full-wave push-pull amplifier using two threelimbed cores is shown in the Figure and comprises a doubler circuit in which one of the load windings 14a, 15a and one of the load windings 14b, 15b is energized by A.C. supply 16a, or 16b, during each half-cycle and differentially energizes a load 21 through a series mixing circuit. By reversing the connection of the bridge rectifiers adjacent the A.C. supplies a parallel mixing circuit may be used. Furthermore, if the bridge rectifiers are replaced by resistors, an A.C. output may be obtained. Control windings 17a, 18a, 17b, 18b, are connected in series and bias windings 19a, 20a, 19b, 20b, are connected in series opposition, or vice versa, depending on the sense of A.C. excitation. The windings 14a, 14b, and 15a, 15b, may be energized in alternate half-cycles to energize the cores alternately; or the windings may be paired to energize 14a, 15b, and 15a, 14b, in alternate half-cycles. The A.C. voltages induced in the control and bias windings may be cancelled out by winding the pairs 17a, 18a; 19a, 20a; 17b, 18b; 19b, 20b, to embrace simultaneously with each turn both outer limbs of the cores they are shown embracing separately. The cores may be built from E-shaped laminations or from laminations forming an uninterrupted three-limbed section. Both cores may be combined in a single core having four windows in two rows of two.
