Patent GB-1338889-A (GB)
Title: Hydraulic boost device
IPC: B60T13/12
Filed: 1972-09-12
Abstract: 1338889 Brake boosters BENDIX CORP 12 Sept 1972 [1 Oct 1971] 42248/72 Heading F2F An hydraulic brake booster has a pressure chamber 30, a valve 38 controlling pressure in the chamber, a piston 74 with one end exposed to the chamber pressure, operator-operated actuating means comprising a force transmitting assembly including a push-rod and means for changing the ratio of displacements of the pushrod with respect to strokes of the piston when fluid under pressure is insufficiently supplied in the chamber, the means connecting the piston and the valve, a fluid cavity between the piston and the push rod, and means for trapping the fluid in the cavity during insufficient pressure input for controlling the travel of the push-rod with respect to the piston. During non-actuation of a brake pedal 90, fluid from a power steering pump 12 flows through a bootster inlet 18 to an outlet 20 to the steering device 14. The chamber 30 is exhausted via passages 51, 48, 50 in the spool valve 38 and an exhaust port 22. Upon pedal actuation, via a rod 94C, a sleeve 94B and a rod 94A, a lever 122 is pivoted about a pivot 124 which, through a sleeve 129 and a spring 142, moves the spool valve 38 leftwardly, to allow fluid flow from inlet 18 to the chamber 30 and preventing its exchaust, for pressure build-up. Some of the fluid at inlet 18 is still allowed to pass to outlet 20 for steering purposes. The increasing pressure in the chamber 30 moves the piston 74, to operate a master cylinder, and moves the pivot 124 moving the spool valve 38 rightwardly to produce a given piston movement with respect to movement of the pedal 90. If there is a malfunction in the booster whereby the chamber pressure is reduced, the booster has a direct mechanical connection between the rod 94A and the piston 74, the rod having a head 108 sliding in the piston. However, this would require a large initial pedal movement for take-up in this connection. This is avoided by a passage 117 connecting the chamber 30 with the cavity in the piston 74 bounded by the head 108 being covered by a sleeve 112, which also carries pins 120 connected to the lever 122, spring- biased against the head 108. Upon malfunction, the spring 144 is collapsed by the required pedal force for the mechanical actuation, the sleeve 112 being held by the lever 122, so that it slides on the rod 94A to provide the enclosed hydraulic force transmitting cavity. A shut-off valve 128 cuts off air flow between the chamber 30 and the passage 48 in the spool valve 38 when a spring force 132 is overcome. An orifice 154 allows restricted flow into a chamber 152 in the valve 128.

Title: Improvements in or relating to ferroresonant voltage regulator devices
IPC: H03F9/02
Filed: 1969-09-05
Abstract: 1,255,239. Automatic voltage control. NORTH ELECTRIC CO. Sept. 5, 1969 [Oct. 7, 1968], No.44136/69. Headings G3R and G3X. A ferroresonant voltage regulator comprises a transformer having a three-limb core whose centre limb 20 carries the A.C. supplied input winding 28, output windings 34A, 34B supplying loads 60A, 60B, a winding 40 supplying a capacitor 48 which is resonantly discharged through an inductor 50 by anti-parallel connected SCRs 52, 54 and a feedback winding 64 which supplies the control circuit determining the firing instants of SCRs 52, 54, the winding 28 being separated from its fellows by a magnetic shunt 24 which forms airgaps with the two outer limbs, Fig. 1 (not shown). The firing points of the SCRs 52, 54 are automatically varied to hold constant the time integral of the voltage over each half cycle of the output, firing occurring near the end of each half cycle when the portion of the core carrying the windings 34, 40 is driven into saturation. An integrator circuit 80 provides a signal representative of the time integral of the voltage to a level detector 82 supplied via members 118, 122, 124 with a reference signal, the arrangement being such that when a predetermined relationship between these two signals is reached, an output pulse is applied to a pulse amplifier 86 and thence to SCRs 52, 54 via the pulse transformer 134. Members 122, 124 also form a reset circuit 88 for the discharge of integrator capacitor 114 after each pulse generation, the instant of which is automatically varied with variations of the A. C. supply to winding 28 (and hence of the time integral of the voltage) to maintain the output voltage of windings 34A, 34B constant. To minimize the effect of changes of temperature and frequency, a further feedback signal is applied to the level detector 82 from an amplifier 152 which receives the output of a voltage detector 148 comprising a differential transistor amplifier 170, 172 supplied with a reference signal from members 164, 166 and with a signal obtained from the winding 64 via members 154, 156, 158, 160, 162. This feedback signal has the effect of altering the level set by the reference circuit 118, 122, 124. The output windings 34A, 34B may supply A. C. or D.C. voltages, which may be sensed and compared with a reference to provide a further feedback signal for transmission to the level detector via an amplifier, Figs. 3A and 3B (not shown). The sensed value may be RMS, peak or rectified average. In Fig.4A the inductor forms part of the structure of the ferroresonant transformer, whose centre limb 220 has two magnetic shunts 224, 245, an input winding 228, a load winding 234, a feedback winding 264, a capacitor winding 240 and a winding 247 shunted by anti-parallel connected SCRs 252, 254 fired by the control circuit 280. The method of operation of this embodiment is discussed, Fig. 5 (not shown).

Abstract: 1,000,511. Tube-splicing apparatus. DUNLOP RUBBER CO. Ltd. Dec. 8, 1961 [Dec. 23, 1960], No. 44205/60. Heading B4B. Apparatus for joining unvulcanized rubber tube ends comprises a pair of gripping members, one for each end, for gripping the outer surface of a rubber tube and supporting it in annular form considered cross-sectionally of the tube, the gripping members being disposed on a common axis and being movable towards and away from one another along the said axis, a support for the tube ends positioned between the gripping members and movable transversely with respect to the said axis, and a knife for each tube end movable transversely with respect to the said axis to sever a portion of said tube held in the support from a portion of said tube held in the associated gripping member. The mode of operation is as follows: two ends of a loop of rubber stock are inserted in the support 49, the operator shuts the safety lid (not shown) which operates the starter switch. The cam-shaft 35 begins to rotate. The clamp jaws 12, 13 are closed, then the cam 56 operates the heated blades 52, 53 to cut through the tube ends to provide a fresh surface. The carriages 7 are then drawn apart a little and the blades are lowered. The support 44 is then drawn well clear of the common axis of the gripping members at the same time bringing the valve which the operator placed in the slot 51 into a position between the tube ends. The carriages are then moved towards one another to press the two ends together firmly round the valve. At the end of the dwell period, the clamp jaws are opened and tube ejection plungers (not shown) free the tube from the clamp jaws. The carriages move back to their original positions. The operator then raises the transparent cover, removes the joined tube, and clears the trimmed ends of the tube from the sockets in the support.
