Title: Furnaces
IPC: C21D9/00
Filed: 1980-10-24
Abstract: Components such as brass billets 15 are heated by passage through a tubular member 10 whose outer peripheral surface is heated by means of electrical heating elements 14 provided on the internal surface of a heat-resisting and lagged outer casing 11. In the event that movement of the billets through the tubular member is halted, the billets are prevented from attaining an excessive temperature by operation of an air injection unit 16 which causes cooling air to flow through the tubular member 10. An end of the tubular member 10 adjacent the unit 16 is chamfered to create a venturi effect whereby air injected by the unit 16 draws in ambient air from outside the furnace. <IMAGE>

Title: Amusement and gaming machines
IPC: G07F17/34
Filed: 1981-01-28
Abstract: A fruit machine in which rotatable reels are ordinarily controlled via drives 10 from a computer control circuit along buses 14. When a button 25 is pressed after the end of a normal game, 2 to 1 selectors 16 change control to a bus 44 on the output of a shift register 46. This rotates the reels for a predetermined time to shuffle the combination of symbols displayed on the reels. If desired, only one or some of the reels may be thus shuffled, and the reels may rotate in the same direction as during the normal game, or in the reverse direction. The shuffling feature may be provided by the main computer control instead of by the circuitry shown. <IMAGE>

Patent GB-2117653-A (GB)
Title: Cards for games of skill or chance
Inventor: BUCKLE LAWRENCE ROBERT
IPC: A63F3/06
Filed: 1982-04-07
Abstract: Printed cards issued to players for use in certain games, e.g. 'bingo', are customarily marked by the player for record purposes. In practice such cards are used only once, since attempts to erase the mark on the usual paper cards soon leads to destruction of the printing and/or the card. A durable card of the invention for use in such games is manufactured of rigid plastic sheet permanently printed with designs or characters, and is capable of being marked in the course of the game with temporary marks which may, however, be readily erased without affecting the permanent printed matter, so that the card is re-usable many times. The card may be of PVC or cellulose acetate and may be reverse printed and then flood coated on the reverse side with a contrasting colour coat.
Patent GB-2097188-A (GB)
Title: Field effect semiconductor device
IPC: H01L21/337
Filed: 1982-04-15
Abstract: A high frequency, high power field effect semi-conductor device adapted for use in the common gate circuit configuration includes an ohmic source region (14) and an ohmic drain region (12) formed in the top surface of a high resistivity layer (10) of semiconductor material. A planar gate region (16), including a rectifying gate junction (18), is formed on the bottom surface of the high resistivity layer. A current barrier (28), formed in the high resistivity layer between the source and drain regions, restricts current flowing between the source and drain regions to a portion of the high resistivity layer near the gate junction. The device exhibits unsaturated operating characteristics similar to those of the static induction transistor. The current barrier may comprise an unfilled V- shaped groove, a thick locally oxidized region, or a very high resistivity region produced by implantation of hydrogen or by radiation damage of the semiconductor. The gate may be a PN junction or a Schottky contact. <IMAGE>

Preferred amine salts for use in the compositions are novel reaction products and are salts obtained from a mixture of aromatic carboxylic acids obtained as a low cost by-product in the commercial production of phthalic anhydride with an amine, which may itself be a commercial by-product from the synthesis of ethanolamine.
Patent GB-2103718-A (GB)
Title: Gas turbine plant
Inventor: VINCIGUERRA COSTANTINO
IPC: F01D11/10
Filed: 1982-08-02
Abstract: The plant has an intermediate connection member (4) between a gas generator (3) and a power stage (7), which member (4) acts as a heat- exchanger for the stator box (6) of the power stage (7) with which lt is thermally in contact at its downstream end (4''). The member (4) is provided with an electric heating coil (15) embedded in its external surface and with an inner annular chamber (17) within which cooling air is caused to flow along a helical path from the downstream end to the upstream end of the chamber. Heating by coil (15) during start-up causes the stator box (6) to expand, thus permitting a reduction in clearance between the rotor discs and box (6). When elevated temperatures have been attained, the cooling air can cause appropriate cooling to ensure efficient operation. Valves 19, 22 can control the cooling air. <IMAGE>

Title: A multiple set jigsaw-type puzzle linked by specified clues
Inventor: BLANCHARD JACK WILLIAM
IPC: A63F9/10
Filed: 1982-12-16
Abstract: The puzzle differs from normal jigsaws because all pieces having the same shape are interchangeable and make recognisable pictures. There are 3 to 7 sets to be provided in a game and a set comprises a portrait, pictures of a location (building, city etc.) and an article related to an incident linking the portrait, location and article. Pieces are in colour and in order for the pieces of persons' faces to be interchangeable, characteristics of hair and skin in areas where the pieces abut each other are depicted by the artist to be very similar. Changing one piece of a portrait will significantly alter it and the correct arrangement can only be determined by following a list of clues. These are limited and do not cover the proximity of every piece and deductions have to be made by the player(s). With 5 sets there are 3, 125 possible faces. <IMAGE>

Title: Hydraulic circuit for crane
Inventor: YOUNG RICKIE A
IPC: B66C13/50
Filed: 1984-06-28
Abstract: A hydraulic circuit for a crane having a plurality of pumps (50, 52, 54) driven by an engine (56) has an unloading valve (58) connected to divert the output of at least one of the pumps (52) to the intake side whenever the power demands by the pumps exceed the power capacity of the engine. Should the hydraulic load on the engine (56) reach a point where the engine is nearing stall, pressure in pilot passage (64) increases to a point where internal relief valve (134) will shift, thus connecting the pilot passage (64) to the reservoir side of the pumps, causing the unloading valve (58) to shift to the left diverting pressure flow from the pump (52) through conduit (70) and blocking conduit (62). <IMAGE>
