Title: Main power supply safety cutout circuit
IPC: H02H3/33
Filed: 1980-07-02
Abstract: An isolation circuit comprises an undervoltage trip coil (6) which is supplied from winding 20 of a transformer 14 and controls main contactor (4) or a moulded case circuit breaker in the main supply line (2) to a machine or group of machines supplied via lines 8, 10, 12 or 16. Rechargable batteries (34) are connected via a push-button switch (45) having double pole changeover contacts (47, 49) so that when the button (45) is not actuated, to engage controls (47), the batteries are parallel and are charged from the mains supply (2), through winding 20.

Title: Electrical grade extrusion filled thermoplastic sheet material and process for the manufacture thereof
IPC: B29C48/90
Filed: 1980-08-01
Abstract: The material may be used in the production of printed circuit boards, and comprises an extruded sheet of a thermoplastic polymer, preferably poly(1,4-butylene terephthalate), containing from about 5 to 60% by weight of reinforcing filler material such as glass fibers, and having a polymer-rich surface, a gloss value of at least 15, and a maximum roughness of about 150 microinches. The material is made by extruding a filled thermoplastic polymer into a continuous laminar melt stream from an extruder (1) and then conveying the laminar melt stream to and through a pressure roll system (11, 12, 13) having hot, highly polished surfaces, which contact the melt stream under temperature and pressure conditions sufficient to cause the filler material to retreat from the surface of the melt stream and to produce a sheet material having a smooth, glossy, polymeric surface thereon. The melt stream is delivered from the extrusion screw to the extrusion die (5), through parts of a breaker plate which gradually converge and change the polymer flow from a corkscrew pattern, to an oriented laminar flow in which the filler material is aligned. <IMAGE>

Title: Improvements in or relating to washing machines and spin-driers
IPC: D06F34/08
Filed: 1981-02-19
Abstract: A washing machine is provided with a moving-magnet accelerometer 6 which is fixed to an end wall of a wash drum assembly and used to detect excessive vibration during the spin cycle. A programme or control circuit 24 responds to the output of the accelerometer 6 and, in the event of an excessive degree of vibration being detected, temporarily de- energises the spin winding 26 of the drive motor and energises its tumble winding 25 so that a distribute cycle takes place during which clothes are redistributed within the wash drum. The accelerometer 6 comprises a magnet 10 and a coil wound on a bobbin 7 relatively movable to generate a signal in the coil dependant upon the degree of vibration. <IMAGE>
Patent GB-2075475-A (GB)
Title: Cartridge filling apparatus
IPC: B65B3/04
Filed: 1981-03-04
Abstract: An apparatus for filling cartridges, with a viscous material such as mastic, includes a loading station (14), a cartridge filling station (16), a cartridge capping station (18) and a packaging station. An endless conveyor 44 carries a number of cradles (40) each of which is in turn moved into position adjacent the loading station. The latter comprises a hopper (20) which passes cartridges one at a time to a dispensing means (32) which dispenses a cartridge to each cradle in turn. A dispensed cartridge is then drawn onto a fling mandrel (48), Fig. 3, at filling station (16), viscous material being injected into the cartridge, the viscosity and pressure of the viscous material combining to force the cartridge slowly off the filling mandrel. Resistance to withdrawal of the cartridge from the filling mandrel is applied to prevent air pockets forming in the cartridge and to ensure correct filling. At capping station (18) capping pressure is maintained on the cap for a preselected time period to allow any compressed air to bleed past the cap. A flap (99) at the packaging station ensures that the cartridge axis is arranged substantially at right angles to its direction of motion so that the cartridge is correctly orientated as it rolls into a box (97). <IMAGE>
Patent GB-2095337-A (GB)
Title: Wave energy conversion unit
IPC: F03B13/18
Filed: 1981-03-19
Abstract: The unit converts wave energy directly into rotary motion for the generation of electrical power. It comprises a sectionalised rotor J and an inlet hopper W both supported by girders forming a boom which spans two pontoons. In use the boom is set at about 30 degrees to the crests of the approaching waves. Each wave enters the hopper via flap valves D and is then deflected by wall surface U so that the foremost section of the wave is directed downwardly into the rotor whereas the rest of the wave is directed upwardly to momentarily provide a potential energy store before passing down through the rotor. The water is discharged from the rotor into the wave trough via flap valve G. The rotor sections are interconnected by flexible couplings and drive a D.C. generator through a gearbox system. Several units may be linked together and function additionally as a barrier or breakwater. <IMAGE>

Title: Continuous speech recognition
IPC: G10L15/10
Filed: 1981-04-06
Abstract: Recognition of continuous speech by comparison with prestored isolated words may be confused by the merging together of spoken adjacent words (coarticulation). Improved recognition is attained by generating overlap-words, e.g., words whose first phoneme is the end phoneme of the preceding word in a string of words. The reference candidate series of overlap-words is transformed under dynamic time warping so as to time-match the utterance series of overlap-words.

Patent GB-2097894-A (GB)
Title: Self-adjusting shock absorber having staged metering for different loads
IPC: B61F5/12
Filed: 1981-05-01
Abstract: In a fluid displacement-type shock absorber, a piston responding to an impacting load moves within a cylinder, forcing hydraulic fluid therein out of one or more orifices into a reservoir. The resistive force of the piston depends upon its velocity, and the area of the orifice or orifices which control the rate at which the fluid can be displaced. The total available orifice area for discharging fluid from the cylinder is progressively reduced as the piston is displaced from its initial position upon impact. According to the invention the fixed orifice structure defines successive control regions, each of which is designed to provide a predetermined resistance profile and related deceleration control for a respective load system or mass system. The lightest mass system, travelling at its maximum velocity within the design range, reaches its limiting deceleration rate in the first control region. The heaviest mass system travelling at its lowest velocity within the design range, reaches its limiting deceleration rate in the last control region. All loads in the design range are decelerated over the full stroke of the piston in being brought to rest. <IMAGE>
