Title: Precision angle and wavelength measurement apparatus using an acousto-optic cell
Inventor: LAWRENCE MARTIN
IPC: G01D5/30
Filed: 1988-09-05
Abstract: Apparatus for measuring angular deflection or a change in wavelength of a light source consists of a photosensitive array SP linked to an acousto-optic cell, with this array providing electrical feedback to the cell in order to return a deflected light spot to a null position. The apparatus also comprises collimating and beam deflecting optics L1, L2, M and electronic signal generators and amplifiers. The difference between the initial signal to the acousto-optic cell and that required to return the deflected light spot to the null position gives a measure of the angular deflection or change in optical wavelength. <IMAGE>

Title: Electronic noise attenuation system
Inventor: TAKAHASHI MINORU
IPC: H04R3/00
Filed: 1989-03-02
Abstract: The invention provides an electronic noise attenuation system for attenuating a sound wave propagated from a source of noise by generating another sound wave 180 DEG  out of phase and having the same sound pressure as the propagated sound wave from an electro-mechanical transducer disposed in a propagation passage 1 of sound waves. In the system, a drive signal for driving the electro-mechanic transducers is generated in accordance with output signals respectively output from upstream-side and downstream-side mechano-electric transducers M1, M2, respectively disposed in the propagation passage with the electro-mechanic transducer therebetween. The drive signal is created by performing an operation on a difference signal between the output signal of the upstream mechano-electric transducer M1 and the drive signal according to a transfer function. The transfer function is determined in accordance with the difference signal and the output signal of the downstream mechano-electric transducer M2.

Patent GB-2216976-A (GB)
Title: Tongue and groove joints
Inventor: PARASIN ALEXANDER V
IPC: E04F15/02
Filed: 1989-03-13
Abstract: A tongue and groove construction panel in which the tongue 12 has a triangular cross-section extending along a convex edge formed by sloping surfaces 20, 22 that slope away from the junctions of the tongue and the said edge. The groove 14 comprises a triangular cavity formed in a concave edge formed with inwardly sloping surfaces 24, 25. When the panel is joined to a similar panel, the outer surfaces of the joined panels are spaced slightly at the joint due to the angles of the sloping surfaces. Such an arrangement allows for swelling of the tongue and groove joint due to moisture without the buildup of internal stresses which would tend to cause buckling at the joint. <IMAGE>

Title: Testing semi-conductor devices
Inventor: HORIE HAJIME
IPC: G01R31/26
Filed: 1989-05-25
Abstract: In a method of testing semiconductor devices A,B in measuring sections 1,2 and using a programmable power source 13, a detector 14 and a control section 15, switches SW1, SW2 are controlled to allow (Fig. 3) tests 1-4 to be performed sequentially on device A, the second test being performed simultaneously on B with the devices A and B connected in parallel. If test 2 is passed in the first sequence, it is not then repeated in a second sequence 1,3,4 performed on B. If test 2 is failed (Fig. 4) it is then repeated on A alone in a sequence 1,2,2,3,4 and also included in a second sequence 1,2,3,4 on B. The tests may include leakage current and withstand voltage tests on diodes.

Title: Sensing device
Inventor: MULLINS COLIN ARTHUR
IPC: F41A19/63
Filed: 1989-07-21
Abstract: A device for sensing the presence/absence of ferro-magnetic material has a Hall-effect transducer 23 adjacent to a magnet 24 which is movable relative to the transducer. The magnet moves by attraction when ferro-magnetic material is brought adjacent the transducer and signals are produced accordingly. As shown the device detects the presence of a ferromagnetic casing of a rocket 10 (or ferromagnetic material thereon) in a rocket launcher. When the bottom edge 21 of the rocket casing is on a stop surface 20, the magnet 24 is attracted to produce a corresponding signal on cables 25. A secondary magnetic coil 12 on the rocket is then in its proper launch position around primary coil 13 on the launcher. <IMAGE>

Title: Power economiser motor control system
Inventor: ELDERKIN PATRICK JOHN
IPC: H02P7/00
Filed: 1989-10-11
Abstract: The economiser system supplies electrical power to a motor such as that driving a freezer compressor or the like. Voltage reduction means TX1 are connected to a mains input. and at least two feeds, such as 240V and 190V, pass from the voltage reduction means to a switch RL1 so as to connect an output to the motor. One feed is at a lower voltage than the other. Sensing means R1, IC1 sense when power in excess of a minimum required is being delivered to the motor and, in response thereto, change the output switch RL1 from the higher voltage feed (240V) to the lower voltage feed (190V). The lower voltage feed may be connected to a triac TRIAC1 controlled in response to the output of the sensing means IC1 so as further to reduce power supplied to the motors. The power is reduced until the motor begins to approach stalling speed and when such a condition is sensed the power is increased marginally to prevent stalling. <IMAGE>

Title: Waterheating apparatus
Inventor: GRIFFITHS RICHARD MARTYN
IPC: F24D19/10
Filed: 1991-09-27
Abstract: A domestic hot water/central heating system of the thermal storage type comprises a cylinder 1 containing primary hot water 2 heated by a boiler 3. Domestic, ie secondary, hot water is generated, on demand, by the passage of mains cold water through finned tubing 7, 7' immersed in the primary hot water 2 and the central heating circuit is heated by pumping primary hot water 2 around the circuit. In order to improve the year round efficiency of the system, the primary hot water 2 is maintained at about 80 DEG  C when the central heating is operative, for example during the winter, but at a lower temperature, for example around 65  DEG C, when the central heating is not required, for example in the summer. Maintenance of the primary hot water temperature at the respective desired values is controlled by a thermistor 5 whose output is fed to a control unit 17 which in turn controls operation of the boiler 3. <IMAGE>

Abstract: 912,888. Foamed thermoplastic materials. FOSTER GRANT CO. Inc. July 5, 1960 [July 22, 1959], No. 23514/60. Class 2(6) [Also in Group V] A thermoplastic polymer and a foaming agent are fed by hoppers 5, 6, respectively to a screw 2 of an extrusion machine having several orifices 16. The extruded strands expand on leaving the orifices and coalesce. The material may pass through a heated or cooled former 11. Endless belts 14 remove the material, and the rate of take-off may be varied to ensure that a back-pressure is set up. If prefoamed beads are used the hopper 6 is closed. The temperature of the machine is controlled by jackets 8, 81. The flow through the orifices is controlled by valves 17. Dyes may be fed through the valves to each strand to give a multicoloured article. The thermoplastic material may be a monovinyl aromatic compound, e.g. styrene, vinyltoluene, vinylxylene, ethylvinylbenzene, parachlorostyrene, meta-chlorostyrene, para-isopropylstyrene, para-bromostyrene, and ethylvinyltoluene. Alternatively, polythene, polypropylene, polyisobutylene, poly-methylmethacrylate or copolymers of methylmethacrylate and styrene or styrene and alphamethylstyrene may be used. The polystyrene may contain a small amount of rubber. The blowing agent may be a gas, e.g. propane, butane, ethylene, propylene, butylene, carbon dioxide, "Freon" (Registered Trade Mark), nitrogen or air, a liquid, e.g. methyl chloride, pentane, hexane, water, or a solid, e.g. ammonium carbonate or bicarbonate, potassium bicarbonate, diazoaminobenzene, diazoaminotoluene, azodicarbonamide, and diazoisobutyronitrile. Specific examples are described using polystyrene and butane, propane or a mixture thereof. The cooled, set foam may be reheated in a steam bath, where it expands slowly with a final release of blowing agent. On cooling, the cell walls of the foam partly collapse. It is stated that this gives a highly flexible foam.
