Abstract: 1,042,760. Hydraulic vehicle braking systems. BARMER MASCHINENFABRIK A.G. Dec. 20, 1963. [Dec. 22, 1962], No. 50429/63. Heading F2F. In an hydraulic braking system for a vehicle, of the kind wherein the driver's effort on a pedal 4 is divided between the piston 2 of a servo-operated master cylinder 1 and a valve controlling the application and release of hydraulic pressure fluid, supplied by a pressure source, to and from a booster chamber of the cylinder, the cylinder 1 and piston 2 are stepped whereby the end 9 of smaller area acts on a liquid column, connected at 8 to the brake cylinders, and the end 10 of larger area is acted on by the hydraulic pressure fluid, and the valve assembly is biased by a spring 21 to maintain it closed until a predetermined pressure has built up in the brake cylinders. The pedal effort is divided either, as shown, by a two-armed lever 6 pivoted to the pedal at 5, one end acting via a push rod 7 on the piston 2 and the other end acting on a push rod 22 of the valve assembly, or the two push rods are acted upon by the pistons of two slave cylinders operated via an hydraulic connection from a master cylinder operated by the pedal. The valve comprises a casing 12 providing an outlet chamber 20 connected by a passage 11 to the booster chamber, an exhaust chamber 16 connected via outlet 19 to a sump, and a bore receiving the push rod 22 and a valve plunger 17 which carries a valve element 13, a reduced portion of the bore forming an inlet chamber 15 connected via inlet 14 to a reservoir supplied by a pump. The spring 21 maintains the parts as shown until overcome by a force corresponding to a predetermined brake cylinder pressure, whereupon the valve element 13 is moved away from its seat, admitting hydraulic pressure fluid to the booster chamber until pressure in the booster chamber rises sufficiently to reclose the valve. Upon removal of pedal effort, the pressure in the booster chamber causes the fluid to flow through a bore 18 in the plunger 17 and in an extension 24 to lift the push rod 22, so opening a release valve formed by a seal 23 on the push rod and the flared upper end of the plunger 17 communicating with the bore 18.

Abstract: 1,204,427. Keyboards. NIXDORF COMPUTER A.G. 11 Nov., 1968 [10 Nov., 1967], No. 53290/68. Heading G4H. [Also in Division H3] A magnetic switch comprises a closed magnetic core 1, Fig. 1, having a primary coil 2 and at least one secondary coil 3 the core being saturable by magnet 4 mounted directly on a key lever 6 and movable into and out of a position in which it causes saturation of the core 1. The core is normally saturated so that there is no magnetic link between the primary and secondary coils, and a signal on the primary causes no output from the secondary coil. When the key is pressed the magnet is removed and the coil is no longer saturated so that an output is obtained from the secondary. In another form the key may bring the shield between the core 1 and the magnet 4 which normally holds it saturated. In a keyboard there is a core 1 for each key, all the primary coils being connected in series. The secondaries are each individually connected to an output amplifier. Secondary coils, one on each core, may be connected in series to indicate whether any key has been operated and the signal may serve to lock other keys against operation. Instead of a single output coil, each core may have a coded group of secondary coils, as shown in Fig. 6. Each output lead is connected to a different group of secondary coils so that a different pattern of outputs is obtained for each key. Secondary coils may be provided in a complementary arrangement, the output lead 25 for example being paired with lead 27, and lead 26 with lead 28. If two keys, say 20 and 21, are pressed in error outputs are obtained from both of a pair of leads 25, 27. And gate 29 responds to this condition to give an error signal. The error signals are connected by OR gate 30 to output 31.

In a military vehicle equipped with a gun in a fixed mounting, control means are provided to steer the vehicle from two positions, there being means for simultaneously rendering one steering control operative and the other inoperative. The vehicle may be steered by the mechanism described in Specification 1,104,864 having a single input member. The two control means include linkworks having input members 10 and 12, respectively, to a transmission member, Fig. 4, having a single output member 8 to the steering mechanism. The normal controls of the vehicle include the steering means associated with the linkwork 10. The links 10 and 12 are connected to cranks 33 and 37 which are connected to clutch members 31 and 35 respectively and which are pivoted in members 39 and 40 attached to a shaft 41. A shaft 28 has a permanent bevel wheeled connection with the shaft 8 and clutch members 29 and 30 which can co-operate with the clutch members 31 and 35. The shaft 41 is axially slidable and is normally urged by a spring 44 into a position wherein the clutch members 30 and 35 are in engagement. An hydraulic piston 48 is formed at the lower end of shaft 41 for moving the shaft against the pressure of the spring 44 into the position where the clutch members 31 and 29 are engaged and the clutch members 30 and 35 are disengaged.

Pulses are produced when the input signal crosses a predetermined reference level e.g. zero, in addition to those produced to represent the variation or the integrated variation of the input signal since the preceding pulse. In one embodiment, Fig. 2, the input 12 is clamped momentarily to zero each time an output pulse is produced at 13, by means of a clamp 2. The signal variation occurring after each pulse is integrated at 3 and the integrated variation is momentarily clamped to zero at 4 when an output pulse occurs at 13. The outputs of clamp 4 and a zero crossing detector 1 are added at 5 and applied to positive and negative threshold triggers 6, 7 feeding pulse generators 8, 9 whose positive and negative outputs are added at 11 to form the combined area delta and zero cross (ADOX) modulation pulse train. The circuit may be modified, Fig. 4 (not shown), by the inclusion of inhibit gates between triggers 6, 7 and their respective pulse generators 8, 9 to prevent an output pulse being generated until a predetermined interval has elapsed after the preceding pulse. In another embodiment, Fig. 6 (not shown), clamp 2 is replaced by a differential amplifier receiving its second input from a step-wave generator coupled to output 13. The output of the differential amplifier may be fed to an integrator and clamp as at 3, 4 or may be fed directly to adder 5.

Should the latter limit value be reached, object E cannot approach the wheel C, and should a predetermined lower limit value be reached, axis A moves rearward. The object E is thus profiled in accordance with the pattern P under controlled grinding pressure. The voltage amplified output of pressure detector F is compared, in units CP 1 , CP 2  with voltages e 1 , e 2  representing lower and upper pressure limits, gates AD 1 , AD 2 , AD 3 , ND co-operating to ensure that servo forward drive pulses are delivered when the pressure is below the lower limit, or rearward drive pulses, when the pressure is above the upper limit, both provided that, as detected by comparator CP 3 , the pattern has not been reached. Should the pattern be reached, gate AD3 is disenabled, so that no servo forward drive pulses can be delivered. Should the lower limit of displacement be reached, as detected in comparator CP4, rearward servo drive pulses are delivered. Changeover of trigger switch CS at the end of a shaping operation disenables gate AD 1 , rearward servo drive pulses being provided until limit switch LS operates. Comparator units CP 1 -CP 4  may have hysteresis characteristics. Optical or magnetic pattern detection may be used.

A Gray-code counter comprises for each stage a pair of flip-flops, the second changing state only when the first changes state in one direction and the first being controlled by the state of the second flip-flop of all preceding stages. Initially all the odd-numbered flip-flops FF1 &c. are in state 0-1, and the even-numbered flip-flops FF2 &c. in state 1-0 so that the inverse outputs #A-#H are marked. The end of the first clock pulse reverses FF1 which therefore reverses FF2 to mark output H. The end of the second pulse restores FF1 without affecting FF2. It also passes through an AND gate to reverse FF3 and therefore FF4 to mark output G. The third pulse deletes the marking on H and the fourth pulse reverses FF5, FF6 to mark F, and so on. All flip-flops can be set to initial state by marking R. The stages can be modified as shown in the alternative part of the Figure.
