Patent GB-2041094-A (GB)
Title: Wave energy power plant
IPC: F03B13/14
Filed: 1979-12-05
Abstract: A power plant extracts energy from water waves, for example sea waves, by first converting the wave motion of the water into the motion of a flowing body of water. The water flows in a reservoir and is arranged to rotate a turbine which, in turn, generates electrical power. The power plant may be combined with one generating power from tidal movements. <IMAGE>
Patent GB-2041285-A (GB)
Title: Bonded Plastics Workpieces
IPC: B29C39/00
Filed: 1980-02-01
Abstract: A bonded workpiece is produced by moulding a resin material in a mould and in contact with a cross- linkable elastomeric material, either or each material containing a compound or group which reacts with the other material, under the conditions of the process, thereby bonding the materials together at their mutual boundary. The mouldable resin may be e.g. an epoxy resin containing a polyamine hardener while the elastomer is e.g. an acrylonitrile-butadiene copolymer containing precipitated silica. Both materials may be injected jointly into a mould in liquid or other form, or one may be injected onto a preform of the other. Alternatively completely reacted moulds of both may be compacted in a mould for reaction.

Title: Stone spreading trailer
IPC: B60P1/36
Filed: 1980-05-02
Abstract: The invention relates to a stone spreading trailer (1) towable behind a tractor, and comprising a hopper (2) mounted on a chassis (3). A conveyor boom (5) extends from one side of the chassis at right angles to the longitudinal axis of the chassis (3) and is adapted to convey stones exiting through an outlet in the bottom of the hopper. The boom is comprised of two parts (6, 7) pivoted together and swingable by means of hydraulic rams from a position in which the boom is fully extended to a position in which the outermost part (7) is substantially vertical and stowed alongside the hopper (2) for transport purposes. The hopper (2) is so positioned on the chassis (3) that the longitudinal axis of the hopper (2) is offset laterally relative to the longitudinal axis of the chassis (3) and to that side of the chassis (3) opposite to that from which the boom (5) extends, so as to counter-balance the boom (5) when fully extended. <IMAGE>
Patent GB-2053487-A (GB)
Title: Inductive differential position sensor
IPC: G01D5/248
Filed: 1980-06-12
Abstract: Two inductors (L1, L2) are arranged on respective limbs of a common iron core along which a short-circuit ring is displaceable (linearly or arcuately) in accordance with the displacement value to be measured. The outputs from the two coils are fed to an integrator (25) whose output is in turn connected to a Schmitt trigger (29). The output of the Schmitt trigger is fed back alternately to the two coils via a change-over switch(s) to form an oscillator whose frequency depends upon the inductance (L1 or L2) of the respective coil and thereby upon the displacement value to be measured. A flip-flop (32) produces an output voltage (UA) whose duty ratio depends upon the oscillation periods obtained by the two inductances (L1 and L2). The change-over switch(s) is controlled by the flip-flop output (33). By applying the output voltage (UA) to a low-pass filter an analog function of the measured displacement value is obtained. Alternatively a digital function can be obtained by applying the output voltage (UA) to a counter. <IMAGE>

Patent GB-2065993-A (GB)
Title: Electrical connector
IPC: H01R13/11
Filed: 1980-12-01
Abstract: An electrical connector having interengaging male and female parts, wherein one part, especially but not exclusively the female part, comprises a sleeve (26) having a slotted region (30) between two solid annular end regions. The slots are preferably of a helical form. For a female part, the slotted region has a reduced diameter compared with that of the solid annular end regions; the converse for a male part. The invention also concerns several methods of production, including the machining of a metal rod sleeve or sleeve blank resulting in an intermediate product of uniform diameter end to end, and the working of this sleeve to produce differential diameters. The latter step preferably consists in twisting the intermediate sleeve end to end about its axis, whereby initially formed straight slots are transformed into helical slots in the final product. <IMAGE>

Title: Method for the Production of Liquid Carbon Compounds from Coal
IPC: C10G1/00
Filed: 1981-07-13
Abstract: Coal is oxidized at 80 to 300 DEG C in the presence of the vapours of a C1-5 aliphatic alcohol (e.g. methanol), optionally under the introduction of steam, and then the liquid carbon compounds are separated from the resulting product mixture. Air or air of reduced oxygen content (e.g. a mixture of air with carbon dioxide and/or carbon monoxide, which can participate in the reaction, or with nitrogen) is preferably used as the oxidizing agent. The residual solid has a lower sulphur content and an increased combustibility (by virtue of an increased oxygen content) relative to the feed coal.

Title: Signal validation
Inventor: GERGELY STEPHEN
IPC: G08B25/01
Filed: 1982-10-18
Abstract: False alarms occur in equipment for allowing disabled or elderly persons to call for assistance, and similar problems occur in security systems. In the present invention, signals initially generated, for example in calls for assistance, are validated by responses to a sequence of interrogatory signals. A person requiring assistance uses a whistle the sound of which is picked up by a microphone 18 in the person's room. A control unit 10 then uses a buzzer 20 to generate one or two sounds which the person repeats using the whistle, to validate the original signal. If the response signals are within predetermined limits, a terminal unit 12 connects the control unit to a central station 14 by way of a telephone line 13 and an alarm is given. <IMAGE>
