Patent GB-2077013-A (GB)
Title: Credit card operated telephone
IPC: G07F7/00
Filed: 1981-05-14
Abstract: A telephone has a card reader with a slot (2) into which a credit card (1) for operating the telephone can be inserted. The slot has a "lead-in" pocket (8) of roughly hemispherical shape to facilitate card insertion. The slot (2) can be closed by a slide (3) with a stud or knob (14) for manual operation, but once the card has been put in for a call the slide is locked by a stud (18) controlled by a magnet (4). At the end of the call the magnet (4) is de-energized so that the slide is released, giving access to the card. This arrangement prevents fraudulent manipulations being carried out on the card. The card may be read holographically. <IMAGE>

Title: A multi-layer metal core circuit board laminate with a controlled thermal coefficient of expansion and method for making same.
IPC: H05K3/46
Filed: 1981-05-28
Abstract: A multi-layer circuit board laminate is disclosed having a controlled thermal coefficient of expansion which is particularly useful in conjunction with leadless components. The subject invention includes incorporating one or more stabilizing metal sheets (24) into a composite multi-layer circuit board laminate assembly (10). The stabilizing metal sheet(s) function(s) to significantly reduce the circuit board laminate's thermal coefficient of expansion, thereby enabling the laminate to be used in conjunction with leadless electronic components. In addition, a novel method is disclosed for fabricating one embodiment of the subject invention and includes a unique two-step lamination process which permits apertures (26) to be provided in the metal stabilizing layer (24) and allows the bonding epoxy resin (22) to solidify within the apertures (26), while simultaneously preventing the entrapment of air. In another embodiment of the subject invention the stabilizing layer is formed of a composite metal-dielectric laminate enabling the layer to be provided with a non-contiguous floating type pattern. Control circuit is then adjusted to increase the current in the foil or wires to increase the temperature thereof and melt the adhesive so that it flows into the material of the sheets. The current is terminated when the adhesive is fully melted so that the adhesive sets to bond the edge portions of the sheets to the tape. <IMAGE>

Title: Inductive switches
Inventor: COX CALVIN HOWARD
IPC: G07D1/00
Filed: 1981-09-15
Abstract: In fruit machines and other amusement with prizes machines which supply prize money and change for coins of a larger denomination from a common pool of coins in the form of a column an inductive switch is provided for sensing the height of the column to avoid the undue depletion of the pool to a level where prizes cannot be paid out. Column of coins 3 is supported in a tube 2 around which two printed circuit coils are coaxially arranged adjacent one another at a predetermined height. The coils are connected in an oscillator circuit such that when the height of the column of coins is level with the coils the oscillator is prevented from oscillating and a relay is de-energised. However when no coins are present at this level the oscillator is free running and the relay energised. <IMAGE>

Title: Improvements in lanterns and other appliances having adjustable stands and/or carrying handles
IPC: F16C11/10
Filed: 1982-04-21
Abstract: A lantern or other appliance has two handles 13 capable of serving also as a stand for the appliance by being rotated to angularly spaced positions respectively below the casing 10. To locate the handles resiliently, the casing has coaxial hollow bosses with diametrically opposite axial slots therein through which project detents 18 formed integrally with a sleeve 17 of resilient plastics material, and the bosses are engaged in respective apertures in the ends of each handle. The apertures have axially serrated peripheries and the detents 18 engage the serrations to locate the handles resiliently. Rotation of the handle about the bosses pushes the detents radially inward, the sleeve 17 flexing resiliently and urging the detents outward into engagement with the next serrations.

Title: Piezoelectric electroacoustic transducer
Inventor: GARNER GEOFFREY MICHAEL
IPC: H04R17/00
Filed: 1984-02-02
Abstract: A piezoelectric electroacoustic transducer consisting of two adjacent polymer films each having electrodes on its two opposite faces with a plastics foam insert between the films which urges the faces of the films into convex surfaces is known from British Patent No: 1,361,371. It has been found however that with smaller transducers of this type (of the order of 50 mm diameter) high levels of sound are difficult to achieve at frequencies of 1 kHz and below. The present invention enables a 50 mm diameter transducer to be made which gives a higher value of sound at these frequencies and consists of using a plastics foam insert having a plurality of cuts or perforations formed through it so that the outer faces of the two films remain convex when the polymer films are energised. <IMAGE>
Patent GB-2138356-A (GB)
Title: Heater manufacturing
Inventor: GRISE FREDERICK GERARD JOSEPH
IPC: B65H39/16
Filed: 1984-02-29
Abstract: A system in which a substrate having a number of longitudinally-extending patterns thereon is slit along longitudinally-extending parallel lines intermediate the patterns so that a longitudinally-extending portion between each pair of patterns may be removed. The substrate, with the portion(s) removed, is then guided between plastic sheets, and the plastic sheets are sealed to each other along the area from which the substrate portion(s) has been removed and along the outside edges of the substrate. The substrate is aligned relative to the slitter using a system that includes a fixed guide roll and axis of which is parallel to and spaced from the slitter and a second guide roll mounted so that its axis is rotatable relative to the axis of the fixed roll in a plane parallel to and about an axis perpendicular to the axis of the fixed guide roll. A sensor intermediate the fixed and second guide rolls senses the transverse position of substrate passing from the second guide roll to the fixed guide roll, and rotates the second guide roll to shift the substrate transversely when transverse misalignment is detected. The gaps in the slitter and guide through which the substrate passes are only slightly thicker than the substrate so as to prevent wrinkling. <IMAGE>

Title: Wheelchair cushion monitor and alarm apparatus
Inventor: ANDREWS BRIAN
IPC: A61G5/10
Filed: 1985-07-19
Abstract: Apparatus for reminding patients with limited movement to perform movements at regular intervals to reduce the risk of pressure sores is described. A load sensor (11) positioned beneath the patient senses the pressure exerted by the weight of the patient. A movement interval timer (MIT) (14) monitors the output of the sensor (11) during a predetermined period. If the pressure is not relieved during this period a signal is fed to the input (13a) of an alarm (13) and to a push-up error counter (PEC) (15), incrementing the counter by one. If the pressure on the sensor (11) is relieved, the MIT (14) is reset. Successive signals resulting from timed periods without movement are fed to the alarm (13) and the PEC (15) and if the accumulated number of signals exceeds a predetermined number a flip-flop (16) is enabled actuating the alarm (13). The alarm signal continues until the patient moves to relieve the load on the sensor, resetting the MIT (14) and PEC (15). <IMAGE>

Title: Two-stroke internal combustion engine
Inventor: ANCHETA ANTONIO
IPC: F02B25/14
Filed: 1986-02-10
Abstract: The scavenging and exhaust ports 26 and 29 are formed in the walls of the cylinder above the bottom dead centre position of the piston head. The lower side of the scavenging port opening inclines inwardly and upwardly toward the cylinder wall so that the flow of scavenging air creates a turbulent action as it enters inside the cylinder for efficient scavenging of the exhaust gases. The scavenging port and exhaust ports are both uncovered and covered simultaneously by the reciprocating piston passing thereby. A sealing "O" ring (50, Fig. 6) is installed into an annular groove (51) formed in each boss (47) of the piston adjacent the end portions of the wristpin (48) to prevent the escape of lubricating oil. Fuel may be injected through an opening (25, Fig. 2) immediately above the part 26 beginning 10 DEG before piston closure of the port 26 and ending 5 DEG  after closure. The ports 26 and 29 are uncovered for 130 to 140 DEG . <IMAGE>
