Title: Magnetic induction couplings
Inventor: HALSTEAD CLIFFORD
IPC: H02K49/04
Filed: 1968-08-15
Abstract: 1,261,894. Magnetic couplings. PYE Ltd. 8 Aug., 1969 [15 Aug., 1968], No. 39154/68. Heading H2A. A magnetic induction coupling comprises a ferromagnetic rotatable part 1 carrying axially 7 extending polepieces 2, a non-ferromagnetic rotatable disc 7 disposed opposite and axially spaced from the polepieces, a magnetic stator 5 having a portion 4 on the opposite side of the disc from the polepieces and a region 18 extending around the periphery of the part 1 to define an air gap 19 extending axially between the region and periphery, and means on the stator for producing a magnetic field 23 which passes from the polepieces through the disc and stator and back through the air gap 19 to impart the same polarity to all the polepieces. The rotor 1 and polepieces 2 may be integral or separate and the latter act as a fan to propel air along a path 24 which may be shrouded over the casing of a prime mover, e.g. an induetion motor 15 driving the rotor 1. The disc 7 forming the output member is carried on a shaft 9 supported in bearings 10, 11 and in modifications may be laminated of different metals, or provided with a peripheral strengthening flange or peripheral notches for use with a light-sensitive tachometric device. The means may be a Cu or Al wire or foil exciting coil 6 or one or more permanent magnets. To vary the torque/speed characteristic, Fig. 3 discloses varying the length of the air gap 3 by angularly moving by angled slots (27) the axial position of the rotor 1 and motor 15. The disc 7 alternatively may be.the input member, and cooling alternatively may be by water or an air or liquid stream over the casing surface.

Title: Improvements in or relating to contents gauges
Inventor: CONNELLY JOHN ALFRED
IPC: G01F23/26

Abstract: 1,086,954. Measuring liquid level. HUNTING ENGINEERING Ltd. Dec. 7, 1965 [Sept. 25, 1964], No.39158/64. Heading G1N. The level of fluent material in a container 1, Fig.1, is determined by means of two capacitive elements 3, 4 extending over different ranges of height in the container, the elements being connected between respective sources of alternating voltage and the input terminals of respective amplifiers, and the outputs from the amplifiers being compared to give an indication of the depth of material. In Fig.2, cross-coupling capacitors C1, C2, equal in capacitance to elements 4 and 3, respectively, when the container is empty, give rise to equal inputs to amplifiers G1, G2 when the level of material is below that at which element 3 is completely covered. Above this level, the difference between the output voltages from the amplifiers is a function of the level. Preferably the gain of G2 is adjusted until the outputs are equal, and the adjustment may be made automatically by a servomotor. The motor may drive a potentiometer slider connected to a meter. Alternatively R1 and R2 may be made variable and adjusted to give zero output voltage, <SP>v</SP>out. The range may be increased by adjusting the gain of both G1 and G2. In a modification Fig. 3 (not shown), the capacitive elements are energized in inverse proportion to their maximum capacitances and the cross-coupling capacitors are energized by corresponding voltages in phase opposition thereto. Resistors are provided in parallel with the capacitors to compensate for the leakage resistance of the probes. The amplifiers in this case have equal gain and the difference between their outputs is indicated directly by a meter. The probes may each consist of a strip of aluminium foil positioned on a wall of glass fibre container 1, each strip being cut in halt-longitudinally to form the two electrodes of a probe. The strips are insulated by a layer of epoxy resin. One probe may be ten times as long as the other, and may extend only to the top of the shorter probe. To obtain an average level of an uneven surface of a fluent solid material probes may be provided on two or more walls and connected in parallel. The shorter probe may extend horizontally instead of vertically, the longer probe then being L-shaped.

Title: Electronic anti-skid control device
IPC: B60T8/70
Filed: 1974-09-17
Abstract: 1458916 Anti-skid braking system SOC ANON DBA 17 Sept 1974 [3 Oct 1973] 40507/74 Heading F2F An electronic anti-skid braking system has a control unit M responsive to an acceleration (or speed) signal of at least one wheel for producing a relief signal d to control a relief solenoid valve S1 for reducing braking pressure during the period of the relief signal d, and an isolation solenoid valve S2 to prevent any increase in the braking pressure during the period of an isolation signal s wherein the isolation signal s is generated in the presence of the relief signal d and ends a fixed interval (e.g. approximately 1 sec.) after the end of the relief signal d. As shown, the control unit M receives on acceleration signal produced by a device G from the output signal of a wheel speed sensor V. The relief signal d is delivered by the control unit M in response to two particular valves g1, g2 of the acceleration-g1 being a negative value indicative of incipient wheel lock and g2 a negative or positive value close to zero which appears when the wheel regains speed due to the reduction in the braking pressure. The relief signal d is also fed to a capacitor C1 with a shunt resistance R1. The capacitor voltage is fed to the first input of a comparator K whose second input is connected to a voltage divider R2, R3, whereby when the potential of the first input is greater than that of the second input, the comparator K delivers at its output the signal s. After the relief signal d ceases, the isolation signal continues until the discharging of the capacitor C1 has rendered the first input of the comparator K less than that of the second input for the fixed interval which depends on the time constant of the network R1, C1. When the isolation valve S2 is operated it cuts off all communication between a master cylinder, and each wheel cylinder on whose pressure the relief valve S1 acts. After the valve S1 has ceased to act at the end of the relief signal the isolation valve S2 maintains in the wheel cylinders the reduced pressure which has established itself. At the end of the isolation signal s the isolation valve S2 returns to its idle position, to allow the pressure in the wheel cylinders to rise again.
