Patent GB-2139842-A (GB)
Title: Acoustic optic device
Inventor: JACKSON J D
IPC: G02F1/335
Filed: 1983-05-11
Abstract: An acousto-optic device employs multiple deflection in order to achieve higher resolution than in conventional devices without increasing the electrical bandwidth. An incident optic beam (I0) is interacted with an acoustic beam produced by a first transducer (22) resulting in a once deflected optic beam (I1). The once deflected beam (I1) is then deflected again by an acoustic beam produced by a second transducer (23) resulting in a twice deflected optic beam (I2), and so on for each transducer of the device. The device can be used for optical scanning in, for example laser printers, where the increase in scan angle due to the multiple deflection provides an increase in the number of resolvable spots for a given electrical bandwidth and optic aperture. Other uses are in frequency agile radio or radar, and the transmission of high frequency r.f. signals, the latter making use of the frequency shifting of the optic beam produced at each acousto-optic interaction. <IMAGE>

Title: Display panels
Inventor: DOBSON CHARLES EDWARD
IPC: B44C5/04
Filed: 1983-06-03
Abstract: A rigid transparent panel 10 has a peelable protective layer 12 on one side and a contact adhesive 16 on the other side covered with a peelable protective sheet 18. The protective sheet 18 is peeled back from one edge and an indicia sheet 24 attached. Then they are fed through a nip between rollers 26, 28, peeling the protective sheet 18 back as it advances. The indicia layer is thus laminated to the panel, the indicia facing the panel and being visible therethrough. <IMAGE>

Title: A high voltage destruction-prevention circuit for a semiconductor integrated circuit device
Inventor: YAMAGUCHI YASUNORI
IPC: G11C11/413
Filed: 1984-12-14
Abstract: An IC is provided with high voltage destruction-preventing circuit (7) which consists of a resistor (R1) and a bipolar lateral transistor (Tr). A first semiconductor region constitutes the resistor (R1), and a second semiconductor region of the same conductivity type as the first semiconductor region is spaced at a predetermined distance from the first semiconductor region. Thus, a parasitic, lateral transistor (Tr) made up of the semiconductor substrate and first and second semiconductor regions is formed. In addition, the length of opposed edges of the first and second semiconductor regions can be set substantially equal to or not less than the channel width of a clamping MISFET (Q2) so as to reduce rapidly and reliably an unexpected, excessively high voltage which could cause destruction of the input circuit. The second semiconductor region may be part of a guard ring or other structure carrying a suitable bias voltage thus reducing the additional space required for the protective circuit. <IMAGE>

Title: Weather seal arrangement
Inventor: INGRAM CHRISTOPHER SAMUEL
IPC: E06B7/22
Filed: 1985-01-30
Abstract: A sealing arrangement for use between fixed 5 and movable 3 window frames uses inner 8 and outer 9 seals with an interspace between them. The outer seal, e.g. of "fin-pile", is less efficient, with respect to air-flow, than the inner one, e.g. of resilient rubber or plastics material, and hence the air pressure in the interspace 10 between the seals tends to equalise with that of the outside atmosphere so that water will drain from the interspace to the outside rather than being sucked inwardly into the interior. <IMAGE>

Title: Rood heat insulation and energy-saving air-conditioning of agricultural buildings
Inventor: GAL PAL
IPC: A01G9/24
Filed: 1985-04-16
Abstract: The roof comprises spaced layers 1,2 bounding an air-space I. Heat radiation 4 is directed parallel to the layers from radiating surfaces 3. The air-space may comprise water- vapour 7 emanating from water streams 5 in channel 8, and the radiant heat absorbed by the vapour increases the enthalpy of the air in the space. Water may condense as dew 10 on the layers and prevent radiation passing through the layers. The layers 1 and 2 may also be cooled by evaporation of the condensation. A warm airstream 16 from the building may be cooled, and reduced in humidity, by contact with walls 3a of the air-space. Circulating water may act in conjunction with a heat-exchanger, e.g. in the soil, to regulate the building temperature. <IMAGE>

Title: Electrolytic cleaning of filters in situ
Inventor: BOWEN DR WILLIAM RICHARD
IPC: C25F1/08
Filed: 1985-06-03
Abstract: @ A porous electrically conducting filter, e.g. a membrane for filtration equipment, is cleaned by setting up an electrochemical cell comprising the membrane as a first electrode (usually the cathode), a second electrode, and an electrolyte capable of being electrolysed to a gaseous product at the first electrode. When a potential is applied across the cell, the gaseous product of electrolysis (e.g. in the form of microbubbles) cleans the surfaces of the membrane by forcing foulant material therefrom.The electrolyte is constituted by the liquid being filtered (with the possible addition of a salt to increase electrical conductivity, if necessary) thus enabling filter cleaning to be carried out in situ whilstthe liquid being filtered continues to be passed through the filter.

Title: Television driver circuit
Inventor: LUCK GRAHAM
IPC: H03K4/62
Filed: 1986-01-29
Abstract: Colour television driver circuit 1 includes input terminals 2, and input coupling capacitor 3, an input- switching transistor 4 with a biasing resistor 5 and a complementary pair of transistors 6 and 7, whose bases are connected directly together and whose emitters are connected directly together and to a driver output transistor 11 via a limiter inductor 12 and a storage capacitor 13. At the start of the fly back period, a pulse causes input transistor 4 to conduct so that output transistor 11 has no base current supply and so is off. Once the flyback period finishes, the pulse is removed from input terminals 2, so that 7 current now flows through capacitor 13 and turns on transistor 11, building up a charge in capacitor 13, the magnitude of current flow limited by resistor 10. At the end of the scan period, transistor 4 receives another pulse, capacitor 13 discharges its contents forcing the base of transistor 11 to go negative thereby producing the required reverse base current to turn off transistor 11. <IMAGE>

IPC: A63F3/00
Filed: 1986-05-16
Abstract: A game for 2 to 4 players. Each player has a camp in which his players start. Each camp consists of 5 circles into which players may be placed. The playing board consists of an inner grid of 121 squares which form one large center square surrounded by 4 camps. Each player has two types of players, U.F.O.'s and E.T.'s. U.F.O.'s can move horizontally or diagonally along the intersections of the inner grid, and along 3/4 arcs. E.T.'s can only move horizontally and diagonally along the grid intersections. The game is ended when one of the players places all of his tokens in the enemy camp which opposes his own camp. The object of the game is to have more points than the opponent(s) at the end of the game. Points are then added up on the basis of the number of U.F.O.'s and E.T.'s which a player has in an enemy camp and also on the basis of the arrangement of those players within the enemy camp. <IMAGE>

Title: Moulding a core within a destructible mould
Inventor: SMITH DAVID
IPC: B22C9/04
Filed: 1986-07-17
Abstract: The core has a complicated shape which has previously necessitated joining together two separately produced core parts. The method (13) comprises taking a pattern of an insitu destroyable material such as polystyrene having a portion to provide at least part of a core defining mould (10), introducing bondable core sand around the pattern, causing the sand to bond to form at least part of the core, and then destroying the pattern. The pattern of insitu destroyable material may provide only part of the core defining mould, the remainder of the mould being provided by a core box (10a, 10b) in which the pattern is positioned and into which the bondable sand is introduced.

Abstract: An electrical apparatus which has a lead for connection to a remote station is provided with a detector to ascertain when the lead is disconnected. An oscillator, based on an operational amplifier (20), includes a positive feedback capacitor (21) and a tuned circuit (22, 23) connected across the amplifier inputs.
