Patent GB-909153-A (GB)
Title: Braking system
IPC: B60T8/36
Filed: 1960-12-21
Abstract: 909,153. Fluid-pressure brakes. BENDIXWESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Dec. 21, 1960 [Dec. 28, 1959], No. 43846/60. Class 103 (1). In a wheel skid-sensitive brake controller having an element responsive to opposing fluid pressures on its two sides, a sudden decrease in one pressure due to excess deceleration causes the element to move a valve in the brake service line from normally open condition to closed and to vent the brake to atmosphere. An air compressor or centrifugal valve 64 driven through an air clutch 88 from a vehicle wheel 10 supplies air to a passage 58 in a skidsensing valve 24 connected between the brake service conduit 16 and a self-lopping brake relay valve 18. Pressure from passage 58 passes by passage 66 to one side of a diaphragm 50, which side is vented to atmosphere through an aperture 90 and connected to the other side of the diaphragm by a restrictor passage 76. A spring-loaded non-return valve 70 also connects the passage 58 with the other side of the diaphragm which is secured to a hollow plunger 44 open to atmosphere at 48. The plunger 44 is urged to the left by a spring 80 to seat a valve 38 against the end of the plunger in conjunction with a weaker spring 40, and to normally hold the valve 38 away from a seating 42 to allow through flow of fluid from conduit 16 to relay valve 18. On brake application, pressure in conduit 16 passes through valve 38 to the relay 18 which closes the exhaust to delivery conduit 22, leading to the brake chamber, and opens that conduit to a reservoir supply from conduit 20. Pressure also passes to engage the clutch 88 and cause the compressor 64 to passage 58. With the wheel 10 rotating, the pressure air opens valve 70 to equalize pressures on each side of the diaphragm 50, and the spring 80 maintains the valve 38, 42 open. When the generated pressure drops, valve 70 closes and air is vented through aperture 92 faster than the balance can be maintained through restrictor 76. Excess pressure on the left-hand side of the diaphragm 50 overcomes the spring 80 and the plunger 44 moves to the right to shut the valve 38, 42 and open the relay conduit 36 to atmosphere through the hollow plunger to release the brakes. The wheel 10 and compressor 64 then accelerate to restore pressure on the right-hand side of the diaphragm faster than air can escape from aperture 92 and the valve 24 returns to its normal condition. The clutch 88 may be controlled by a solenoid responsive to a manual or pedal-operated switch, and the relay 18 may be omitted, the conduit 36 leading to the brake chamber.

Abstract: 1,186,528. Digital/analogue converters. CEAPEREGO S.p.A. 2 Oct., 1967 [4 Oct., 1966], No. 44702/67. Heading G4H. The difference between two digital numbers, by which counters C1-C2, C3-C4 are preset, is determined in analogue form by feeding clock pulses to the counters which, when they reach their maximum counts, apply signals to generators G1, G2. The generators G1, G2 feed squarewave signals to a phase discriminator D, the output voltage from which varies in accordance with the time interval between its inputs. The apparatus may be used for positioning a movable member, the required and actual positions of which are entered by switches I 1 -I 6 , I 7 -I 12  (Fig. 4) into counter C 1 -C 6 , C 7 -C 12  respectively. Each counter comprises three parts, each of two decades, each part being fed with clock pulses of frequency fo. The discriminator D1 receiving the signals from generators G1, G4 associated with the two most significant digits of each counter is first used to control the member until its output becomes zero when the output from the discriminator D2 is used. In the embodiment of Fig. 5 (not shown), all except the most significant part of the counters have three decades, the least significant decade in one part being repeated as the most significant decade of the next part. A frequency divider is included in the most significant part of each counter to equalize the output frequencies of the pulse generators.

Title: Improvements in or relating to bulked continuous filament yarn
Inventor: BRIDGES WILFRED
IPC: D02G1/12
Filed: 1964-11-07
Abstract: In the production of bulked, continuous filament, nylon yarn, a continuous filamentary bundle e.g. a conglomeration of three, individual, 1000 denier, twisted or "twistless" yarns, is mechanically crimped in a stuffing-box.  The crimped bundle, prior to winding-up, is divided into separate bundles e.g. the component yarns, the linear alignment of which is altered by passing them severally along guided paths of different lengths or by stripping different lengths from some bundles and are finally recombined into a single bundle or (composite) yarn.  If recombining is effected before winding-up, the final bulked yarn is wound as an entity; if it occurs thereafter, the bundles are separately wound e.g. as three "biscuits" on one cylinder, and recombining occurs during an unwinding process when the yarn is twisted.  If the crimping operation is regulated by controlled variation in tension of filaments withdrawn from the crimper, the separating and recombining are effected before the recombined bundle contacts a magnetic particle brake.

Abstract: 1407980 Transistor logic circuits INTEGRATED PHOTOMATRIX Ltd 29 Sept 1972 [6 Oct 1971] 46455/71 Heading H3T A shift register stage 20, arranged to conduct current only if a 1 is stored, thus reducing power consumption in the register, consists of two amplifier stages 21, 22 the second 22 having its inverting and non-inverting inputs 40, 44 respectively connected to the output 13 and the inverting input 12 of the first amplifier. In the F.E.T. stage shown, a zero level (" 0 ") at 11 is gated to 12 by F.E.T. 23 in # 1  time to hold F.E.T. 24 off, the same # 1  negative pulse (50, Fig. 7, not shown) also causing F.E.T. 25 to charge node 13 negatively so holding F.E.T. 26 on so as to earth the output 14 to 28. A subsequent negative level (" 1") at 11 (52) is gated by F.E.T. 23 in the next # 1  time (53) to 12, so that F.E.Ts 24, 25 are on together to cause node 13 to adopt an intermediate level which is arranged to be sufficient to hold on F.E.T. 26. Although F.E.T.27 is also on, # 2  is at Ov. At the end of # 1  (53) F.E.Ts 23, 25 go off, and the negative stored charge at 12 holds on F.E.Ts 24 and 27, F.E.T. 26 now therefore being off. The next # 2  pulse (54) passes through F.E.T. 27 to produce an output (55) at 14, the feedback capacitor 46 providing positive feedback to boost conduction of F.E.T. 27 in order to overcome its threshold drop. The next # 1  pulse (after 53) takes point 13 negative again, thereby turning on F.E.T. 26 to earth the output 14 and reset the stage. The next stage 201 is similarly controlled by # 2 , # 1  (i.e. in reverse order). A shift register composed of such stages is used to scan a plurality of photodiodes (61, 61<SP>1</SP> etc., Fig. 8a, not shown) by enabling in turn F.E.Ts (60, 60<SP>1</SP> etc.) connecting them to a common output line. Alternatively, the diode (61) capacitance at one location is charged (from 92) by a F.E.T. (90) turned on by a shift register output (14<SP>1</SP>), which also turns on a F.E.T. (70<SP>1</SP>) at the next location so that current flow from earth (82) through a series F.E.T. (80<SP>1</SP>) controlled by charge remaining on the diode (61<SP>1</SP>) capacitance since it was last charged, can be monitored in an output line (72).
