Filed: 1978-12-14
Abstract: A power press in which a ram 12 is driven towards and away from a press bed 11 so that, in use, a work piece is deformed by a tool 16 mounted between the ram and the press bed is provided with means by which a jam in the press can be released both quickly and simply, this release means comprising a layer 2, 3 of heat softenable rigid plastics material which is located in the press so that the direction of the press stroke is substantially normal to the layer and so that during a pressing operation the layer is subjected to compressive stress in the direction of press stroke, and electrical heating means 5 located so that it is capable of heating the layer 2, 3 of plastics material, when desired, to a temperature sufficient for the plastics material to soften whereby, under compression in the direction of the press stroke, the thickness of the plastics layer 2, 3 decreases. Preferably the electrical heating means 5 comprises an element which is embedded in a metal layer 1 which fits face to face with the plastics layer, and is preferably sandwiched between two plastics layers 2 and 3, to form a spacer assembly 1, 2, 3 which is fitted in the press, usually between the tool 16 and the ram 12, or between the tool 16 and the press bed 11. <IMAGE>

Title: Sterilising fitments for injection devices
IPC: A61M5/00
Filed: 1981-06-02
Abstract: In order to minimise the risk of infection when a large number of animals are injected with the same needle 3, the injecting gun 1 is provided with a stainless steel sleeve 9 which surrounds the needle 3. The sleeve 9 comprises a first tube 10 attached to the needle connecting body 2 and a second tube 11 telescopically slidable within the first tube 10 against a spring 22.

Title: Vehicle indicator device
IPC: B62J6/00
Filed: 1981-09-09
Abstract: A vehicle indicator device for use on a motorcycle provides a fixed number of flashes when operated, and then automatically cancels itself. This is achieved by means of a pulse generating circuit composed of a Schmitt trigger (IC2c), a resistor (R4) and a capacitor (C3). A resettable counter (IC1) counts the pulses produced by the pulse generating circuit whenever the user operates the indicator device. While the counter (IC1) is counting, power is supplied to the left or right indicator lamps. Once the counter (IC1) has counted a predetermined number of pulses power ceases to be supplied to the indicator lamps. A hazard warning option is also incorporated by use of which both right and left indicator lamps are operated independently of the state of the counter. <IMAGE>

Title: Infra-red radiation imaging device arrangements
Inventor: BAKER IAN MARTIN
IPC: H01L27/148
Filed: 1982-07-28
Abstract: An imaging device arrangement comprises infra-red radiation detector elements (10) and signal-processing circuitry including at least one charge-transfer line (30). The detector elements (10) are preferably cadmium mercury telluride photovoltaic diodes formed in a common body or body portion which is secured to a substrate (e.g. of silicon) comprising the charge-transfer line (30). Each detector element (10) is connected between an input connection (2, 3) of the charge-transfer line (30) and a common electrical connection (4). At least one storage electrode (62) and at least one subtraction gate (63) are present at each input connection (2, 3) for subtracting at least one portion (77) of the charge-signal so that only a portion (78) of the charge-signal for each detector element (10) is transferred along the charge-transfer line (30). The subtracted charge (77) is drained away via the radiation detector elements (10) by means of a pulse generator (50) or other voltage switching means which is connected to the common electrical connection (4) to switch the common voltage applied to the detector elements (10). A compact structure with fast draining at each input connection (2, 3) is obtained. The pulse generator (50) can be formed with other pulse generators of the at least one charge-transfer line (30) in a peripheral area of the circuit substrate. <IMAGE>
