Patent GB-2105928-A (GB)
Title: A.c. voltage sensor
Inventor: REARDON DENIS DAVID SILVEY
IPC: H02P9/14
Filed: 1981-07-22
Abstract: An a.c. voltage sensor is used to monitor the output level of an a.c. voltage generator and to produce a control signal which is operative to hold the a.c. output voltage at a predetermined level. A nominal d.c. voltage is derived from the output of the a.c. generator by means of a bridge rectifier 5 and compared with a reference level. The nominal d.c. signal contains an a.c. ripple component, and the invention enables the magnitude of this ripple to be greatly reduced without the need to provide a filter circuit which would adversely extend the time constant of the control circuit. This is achieved by providing resistance (R2, R3, R4) in each input path to the bridge rectifier and a resistor (R1) across the bridge rectifier output, the values of the resistances (R2, R3, R4) w.r.t. that of the resistor (R1) being chosen such that the output ripple has twice the frequency it would have in the absence of the resistances. <IMAGE>

Title: Photographic Material and Process for the Production of Optionally Modified Vesicular Images
IPC: G03C1/73
Filed: 1981-10-02
Abstract: Photographic materials comprising a silver halide emulsion layer with grains which are smaller than 0.3  mu m, a hydrophilic binder e.g. a gelatin and a water-insoluble polymer are useful for the production of modified vesicular images. After imagewise exposure the material is contacted with a substance which decomposes to form a gas e.g. peroxide vapours, and then heated. The exposed silver halide decomposes the peroxide to form gas vesicles. Around the vesicles the water-insoluble polymer separates from the binder so that the image becomes visible when the vesicles are removed by washing, the separated polymer can be dyed. In alternative embodiments the vesicles remain trapped in the material.

Title: Vacuum holding device
Inventor: SMITH HAROLD
IPC: B65B43/30
Filed: 1982-06-22

Title: Improvements in or relating to liquid-dispensing apparatus
Inventor: MORTIMER GEOFFREY HOWARD
IPC: C02F1/68
Filed: 1983-01-21
Abstract: Apparatus to dispense liquid - for instance a flocculant solution - at a rate proportional to the rate of flow of a fluid such as a polluted stream (25) to which the flocculant is to be added. A tube is coiled around a rotor (7) mounted on a structure (1) floating in the stream, and as the rotor is turned by the stream and tube acts as a coil pump. During each complete revolution of the rotor the inlet (14) of the tube takes in a volume of water as it passes below the surface of the stream, followed by a volume of air as it passes above. The volumes of air are increased in pressure as they pass along the length of the coiled tube, and on emerging from the outlet (19) pass by way of a sealed conduct (28) to a sealed reservoir (29). For each volume of pressurised air that the revervoir receives, a related volume of flocculant (31) is displayed from the reservoir into the stream. <IMAGE>

Title: TV cameras; inspecting a subject in a turbid medium
Inventor: GLASGOW JOHN ARTHUR
IPC: G01S17/18
Filed: 1983-04-30
Abstract: An underwater TV camera 1 for use in turbid water conditions transmits pulses of light from a laser 4 and receives the light after reflection from a subject 2 using a conventional TV camera 7. A range gate 5 allows the TV camera to view subjects only within a defined range gate. Instead of opening the range gate 5 for periods equal to the duration of the flashes of light it is allowed to remain open for longer periods thereby improving the field of view. Because of the turbid conditions, this does not degrade to signal-to-noise ratio as much as would be expected in conditions of good visibility. The system may also be applied to ultrasonic cameras and inspection devices, for use in fog or in a radar system. <IMAGE>

Title: Curtain sided vehicles
Inventor: JONES STEPHEN MARK
IPC: B60J5/06
Filed: 1983-08-17
Abstract: A curtain sided vehicle (1) has a curtain (7) suspended from a curtain rail (8) and provided at its lower edge with a cord (16). To close the curtain a roller (10) secured to one end of the curtain (7) is rotated by a ratchet drive (12) to wrap the curtain (7) around the roller and effect tensioning of the curtain in the horizontal direction. As the roller (10) is rotated the cord (16) is wound onto a drum (17) secured to the roller. The tension produced in the cord exerts a vertical force on the curtain (7) and thus rotation of the roller (10) effects simultaneous horizontal and vertical tensioning. <IMAGE>

Patent GB-2148667-A (GB)
Title: System and method for compensating polarization errors
Inventor: CLARK JOHN FULMER
IPC: H04B7/10
Filed: 1984-03-07
Abstract: The method and system is for use with or in e.g. a satellite (S) for compensating for cross coupling of satellite feeder link signals from a first channel (WV) of a first linear polarization (vertical) as received by a first, e.g. linearly, polarized satellite antenna element (110) with adjacent signals from a second channel (LH or UH). The second channel signals are at a generally orthogonal (horizontal linear) polarization. In the presence of liquid precipitation the horizontal component is phasedelayed more than the vertical component. The system includes a second linearly polarized antenna element (113) oriented orthogonal to the first antenna element (110) for sensing the second channel signal, a gain controlled amplifier for reducing the gain of the second channel signals received at the second antenna element (113) in inverse proportion to the sensed amount of cross coupling (depolarization), a phase comparator (143a) for comparing the phases of signals at the frequencies of guard bands between channels, phase shifter (143) for providing 180 DEG phaseshift adjusted in proportion to the phase comparison for inverting and phaseshifting the gain reduced signals and a summer (135) for summing the inverted, phaseshifted reduced gain signals with the first channel signals from said first antenna element (110).   <IMAGE>
