Title: Peristaltic fluid-machines
IPC: F04B43/12
Filed: 1979-08-31
Abstract: A pump displaces different fluids 10 through straight or helical portions of flexible tubes 7. The said portions of the tubes 7 extend through a tubular housing 6 and are squeezed against the inside of the housing by a rotor 11 rotated by a motor 2 through a shaft 3. The tubes 7 may extend straight through the housing 6 parallel (or inclined) to the rotor axis and the rotor 11 may be in the form of a screw having a helical portion 13 (or helically disposed rollers) which squeezes the tubes 7 progressively along their length as the rotor rotates. Alternatively, the tubes 7 may extend helically about the rotor axis, the tubes being squeezed progressively along their lengths by axially extending portions of the rotor, Figs. 6 and 7 (not shown). <IMAGE>

Patent GB-2071382-A (GB)
Title: Coin Testing Device
IPC: G07D5/10
Filed: 1980-03-04
Abstract: For discriminating between coins of substantially the same size but having different edge characteristics, in particular between faceted coins such as the British 50p piece and a false, round, smooth-edged coin having substantially the same effective diameter, the coin testing device throws light from a light emitter (10) onto the edge of a coin (6) passing along a coin path (4). Reflected light from the coin edge is detected by a light detector (12). The slope of the detector output signal indicates the nature of the edge characteristics of the coin. Because the emitter/detector unit (8) in effect measures the curvature of the portion of the coin edge presented to it, the invention also finds application for measuring the curvature and diameter of round coins. In a development the coin is treated as a faceted coin only if the test result, and also the result of a further, mean diameter, test, indicate diameters for the coin which are inconsistent with one another. <IMAGE>

Title: An electric capacitor with a kidney-shaped cross-section
IPC: H01G4/32
Filed: 1980-03-31
Abstract: An electric capacitor comprises a winding 14 of electrically conducting layers and di-electric arranged therebetween. The winding for the new capacitor is produced from an originally round winding flattened on one side 18 so that a substantially kidney-shaped cross-section for the winding results. The original capacitor winding hollow in the centre in the region of the winding mandrel retains a substantially semi-circular shape on one half whereas on its other half it has a substantially flat surface. On the one hand, such a capacitor has a preferred deformable surface in the region of the flattened side and on the other hand it may be combined with a similar capacitor winding with the introduction of a mounting pin to form an arrangement which is easy to handle during manufacture. By using a dielectric which releases gas during thermal overload, the flattened side of the winding is suitable to a considerable extent for the application of a cut-out responsive to internal excess pressure. <IMAGE>

Patent GB-2055271-A (GB)
Title: Television camera
IPC: H04N5/217
Filed: 1980-07-28
Abstract: Microphonics noise in a TV camera tube (2), e.g. due to vibration of a grid, is detected by sampling (SH1) during the time blanking interval (THB). In a first position (p) of a switch (231, 232, 233, 234) the tube is subjected to mechanical shock and the resulting microphonics noise samples used to pull in a phase locked loop oscillator (17) whereby it oscillates at the microphonics frequency. In the second position (q), the oscillator output is fed (24, 233, 25, 9) into the video signal, and the resulting samples nominally phase inverted (14) and combined (11) via a closed switch (15) with the video signal plus oscillator output. Any oscillator output not thereby cancelled out is detected by a second sampling (30) process accumulated over a plurality of fields to produce a correction signal for adjusting the phase shifting of the nominal phase inverter (14). In the third position (r), the oscillator acts on the samples to detect any microphonics, whence the switch (15) now normally open, is closed so that the cancellation of the microphonics can take place as in the previous (q) position. <IMAGE>

Title: Apparatus and Methods for Controlling Induction Motors
IPC: H02P23/00
Filed: 1981-09-25
Abstract: When induction motors are lightly loaded their power factors and efficiency are poor but in the present invention power factor is controlled regardless of load. An induction motor 10 is connected by way of a triac 12 to a supply 11. The voltage across the triac 12 is monitored by a comparator 21 for voltage steps which correspond to current turn-off and a signal is developed at the output of an amplifier 19 which represents error from required phase lag. A comparator 17 and trigger pulse generator 16 responsive to ramp generator 18 trigger the triac 12 in accordance with the error. A circuit 31 overrides the control system during starting. A number of further induction motors may be connected in parallel with the motor 10. <IMAGE>
Patent GB-2111310-A (GB)
Title: Antenna array
Inventor: GUY RONALD FRANK EDWARD
IPC: H01Q21/22
Filed: 1981-11-27
Abstract: Gain characteristics can be achieved by displacing the position of maximum amplitude to a base region of the antenna but maintaining a lesser amplitude peak in the central region. This is as shown in continuous lines in Figure 3A. Also the phase distribution is changed so that the phase lag increases relatively slowly in a lower base region and relatively fast in the central and upper regions of the antenna. This is as shown by the continuous line of Figure 3B. This continuous line has a distinct bend in the upper half of the base region in contrast to the two bends 1 and 2 of the conventional phase distribution shown in chain dotted lines.
