Abstract: 1,050,623. Disc brakes. DUNLOP RUBBER CO. Ltd. Oct. 22, 1963 [Oct. 25, 1962], No. 40346/62. Heading F2E. In a disc brake having a friction element 14 which is guided to move obliquely relative to the disc 10 so as to provide a self-energizing effect, a rigid thrust member 23 applies a thrust in the axial direction of the disc and is displaceable in a direction parallel to the plane of the disc; Means 15 are provided to apply braking pressure to the element 14 through the member 23 and resilient means 25 are provided for restoring the thrust member to its original disposition on release of the braking pressure, the thrust member being free to slide laterally relative to the friction element. As shown, the pad 20 is applied against the disc 10 by a piston cylinder device, the rod 23 being received in a recess of the piston 17 and surrounded by a rubber sleeve 25. A pad on the opposite side of the disc may be applied by a similar piston cylinder device in a fixed caliper or may be applied by the reaction of a movable caliper. In modifications a rod or sphere may abut a boss formed on the piston, a rubber sleeve surrounding both the rod or sphere and the boss. The rubber sleeve may be replaced by a slotted sleeve or springy metal. In another embodiment, Fig. 8 (not shown), the thrust member 60 in the form of a spindle 61 integral with a grooved pulley 62 is returned to its original position by an annular spring member 66. In a further embodiment the thrust member is formed integral with the piston which is provided with a pair of axially spaced resilient sealing rings which restore the piston-thrust member combination to its original position.
Patent GB-1051903-A (GB)
IPC: H03K17/74
Abstract: 1,051,903. Voltage measurement. TEKTRONIX Inc. Feb. 14, 1964 [Feb. 18, 1963], No.6221/64. Heading G1U. [Also in Divisions H3 and H4] An apparatus for sampling a high frequency signal so as to obtain a low frequency reproduction of the signal waveform includes a probe 12 incorporating a diode bridge sampling gate 10 which is normally reverse biased but passes the input signals on the probe connector 14 when interrogating pulses are applied to it, so that the input signals are passed to the high resistance shielded conductor 78. The signals are passed to one input of a differential amplifier 26, the other input being at a reference voltage. The output of the differential amplifier is fed back to the first input via the condenser 32 and resistor 34. The output signal is also fed via an amplifier 58 and memory gate 54 to a Miller memory circuit 62, where the output signal voltage is stored on the Miller capacitor 64. The output of the memory circuit is fed back over the potentiometer 66 to the second input of the differential amplifier to provide the reference voltage required at that input. To provide the necessary gating pulses, a ramp generator 74 is used to control a blocking oscillator 72, which provides a pulse to open the memory gate 54 and also to trigger an interrogating pulse generator 40. This provides opposite polarity pulses, narrower than those which open the memory gate, which are fed to opposite corners of the sampling gate via the conductors 84 and 86. In order to present high impedance to input signals from the gate, these conductors are in the form of a twisted wire pair looped through a ferrite ring 88. The shielded signal lead 78 from the probe is of high resistance material in order to prevent ringing and has a capacitor 44 connected at the sampling gate end between the lead and screen. The system operates so that the Miller memory stores each input signal magnitude successively, the output from the memory giving a low frequency record of the input signal waveform, so long as the ramp generator 74 is not in synchronism with the input frequency. The operational feedback around the differential amplifier 26 is necessary because of the low transmission efficiency of the sampling gate. The amplifier appears to be of large capacity to the input signal so that the capacity of the line between the sampling gate and the amplifier has little effect on the signal.

Composite mats, farbics, &c. are produced by forwarding a fibrous layer 1 through a preheating oven 4 to an electrostatic chamber 9. Measured quantities of powdered resin are introduced into the chamber by distributor 16. The chamber 9 contains a porous plate 10 with metal points 13 connected to one pole of an electric generator 12. The fibres are given an electrostatic charge of one polarity and the resin particles an electrostatic charge of opposite polarity in this chamber so that they are attracted to each other. The impregnated fibrous layer 1 proceeds to an oven 17 where the resin is melted through calender rollers 21 which are cooled and cooling tunnel 22. The sheet may then be rolled up or out into panels and stacked. This apparatus gives preferential deposition of resin on the bottom surface of layer 1. For equal deposition of resin on both surfaces the layer 1 may be led vertically through the electrostatic chamber 9. Examples of fibres forming the mat are glass, quartz, silica, asbestos, carbon, graphite or boron fibres. The resins may be thermoplastic, e.g. polystyrene, copolymers of styrene and acrylonitrile or butadiene, polyethylene, polypropylene and copolymers of propylene and ethylene, polyvinyl chloride and copolymers thereof, methyl polymethacrylate, copolymers of methacrylic or acrylic acid esters polyamides, poly lactams, e.g. polycaprolactam, hexamethylene diamine, polycarbonates, polyphenylene oxide and cellulose derivatives, e.g. cellulose acetate.
