Patent GB-2085541-A (GB)
Title: A bolt for assembling heat exposed constructions
IPC: F16B31/04
Filed: 1981-09-24
Abstract: A bolt for assembling components in a heat exposed construction is provided with a substantially fully longitudinally through bore (19), into which a thermally conductive rod, e.g. of copper, (20) is inserted as a good fit. One end portion (15) of the bolt is directly screwed into one of the components (10), and one end (21) of the rod is soldered within said portion, so that a good heat conducting contact is obtained between the component and the rod (20). Due to the intimate contact of the rod with the bore the entire bolt is quickly heated. <IMAGE>

Title: Local oxidation of semiconductor material
Inventor: KUANGE YI CHIU
IPC: H01L21/3105
Filed: 1982-02-24
Abstract: A method for local oxidation of a semiconductor using only conventional Large Scale Integration (LSI) fabrication techniques is provided which results in an oxide layer without the formation of the so- called "bird's beak" structure. On a semiconductor substrate (117) a mold for oxide is made by forming on the substrate, a trench (121) with sidewalls (125) extending upward to a localized plateau region (123) of the substrate. The sidewalls of the trench and the localized plateau are covered by a masking layer (113, 131) capable of preventing oxidation of the underlying substrate. The unmasked portion of the mold is oxidized to produces localized oxide layer (141) which is substantially free of any "bird's beak" structure. Additional oxide may be deposited and then etched back to fill the groove (153) left when the masking layer (131) is removed. <IMAGE>

Title: Improvements in friction stays for windows
Inventor: DOUGLAS JACK ERNEST
IPC: E05D11/08
Filed: 1982-06-25
Abstract: In a rivetted friction stay for windows, the pivot joint for high performance and simplified assembly includes a plastics coated rivet 8 with a frustoconical head 13 that seats in complementary recess 17 concentric to a hole 16 in a stay arm 6. The stay arm 6 is pivotally connected to a mounting plate 1 by the rivet with the arm 6 and plate 1 being separated by a spacer 9 comprising a support plate 11 and a washer 10. The tail of the rivet is clinched to the underside of the plate 1 to generate the desired friction in the joint and a spiked washer 12 is disposed under the tail on clinching to prevent the rivet rotating relative to the plate 1. Various embodiments of stays with pivot joints are described with different arrangements of spacer and location for the rivet tail. <IMAGE>
Patent GB-2127599-A (GB)
Title: Decoding digital data
Inventor: CHAMBERS JOHN PHILIP
IPC: H03M7/14
Filed: 1982-09-17
Abstract: Distanced codes are highly- redundant codes where the coded states all differ from each other in several different bits. Six input states can be coded by 16 bits such that each code differs from all the others in at least nine bits. At a receiver, any receive code differing from one of the correct codes in less than five positions can thus be assumed to be that code. A read-only memory (ROM) with a 16 bit address input could be used, were such practically available. Instead, some, e.g. thirteen, of the 16 input bits are applied to a first ROM A. Of the total 8192 combinations of these bits all those having five or more disagreements with all the correct codes can be identified by a single 'uncertain' state. The ROM A has then only 62 relevant output states, which can be encoded by six intermediate bits. These are applied to a second 9- input ROM B with the three remaining input bits. ROM B provides six outputs for the six individual correct codes, and a further output for the 'uncertain' condition. Other embodiments use 3 ROMs. <IMAGE>

Title: Device for launching electromagnetic decoys
Inventor: BILLARD ALAIN ANDRE
IPC: F42B5/15
Filed: 1982-12-13
Abstract: In a device for launching electromagnetic eg. radar decoys the members bearing the decoys are housed in cells (L 1 , L 2 , L 3 , L 4 , etc.) each linked to an initiator (I 0 ) which communicates directly with an orifice (I 1 ) for transmitting ignition to cell (L 1 ) and via delay means (I 2 , I 3 , I 4 ) with the corresponding orifices of cells (L 2 , L 3 , L 4 ). Each member comprises a sliding portion (2) having an open major face closed by a cover of which an extension projects opposite an opening (21A) in the wall of a compartment (21) provided for a pyrotechnic charge. The pyrotechnic charge causes ejection of the decoy-bearing sliding member from the launching device, and after a given delay, acts on the extension of the cover in order to remove the latter and thereby cause the decoys to be released. This ensures that the decoys are deployed at the end of a given delay after ejection of the decoy-bearing member from an aircraft.

Title: Electro-magnetic stirring
Inventor: PORTER MALCOLM
IPC: B22D27/02
Filed: 1983-02-11
Abstract: The invention concerns the promotion of stirring of molten material (e.g. steel) within a receptacle such as a mould, vessel, or shell of a partially solidified metal strand emerging from a mould. Polyphase alternating currents are passed through electrically conductive elements located on, or forming part of, or lying adjacent to the receptable surface by joining both current connections of one or more transducers to the conductive elements to cause electrical currents to flow along paths in the elements to induce magnetic fields within the molten material and to promote stirring of the material.

Title: Carbonating apparatus
Inventor: ADAMS FRANCIS JOHN
IPC: B01F3/04
Filed: 1983-05-17
Abstract: A header tank 1, filled with fresh water 2, is connected to a carbonating pressure vessel 4, so that water 2 can flow, under gravity, into the vessel 2 to a level 6, ensuring that an air gap 7 remains above the level 6. A replaceable gas cylinder and valve assembly 9 is connected to a gas nozzle 13, Fig. 2 which extends into the water 5 in vessel 4, so that by actuation of the assembly, pressurised gas enters the vessel 4, thereby effecting carbonation of the water 5.

Title: Electromechanical brake booster
Inventor: OSTWALD FRITZ
IPC: B60T7/04
Filed: 1983-06-03
Abstract: An electro-mechanical brake booster for an automotive vehicle, comprises an electro-motive drive (1) generating the boosting power and a mechanical device (2) which is acted upon by the brake pedal pressure and which supplies the boosted pedal pressure to a brake cylinder. The electro-motive drive (1) has at least two switch conditions, namely a stand-by or no-load switch condition and an operation switch condition. In the stand-by switch condition, the power input (UV) of the electric motor (1) will be reduced by means of a series resistance (R) to such an extent that continuous operation is enabled but there occurs only little wear and little noise is developed. Upon brake application, the series resistance (R) will be bridged by the changing over of a switch (s2) whereby the electric motor (1) switches over to full power (UB) after minimum delay. The switch (s2) may be replaced by a pressure sensor (7) in the push rod (6) connected to an electronic regulator (8) to progressively short the resistance (R) (Fig. 2). <IMAGE>

Title: Gaming or amusement-with-prizes machines
Inventor: PARKER ALAN GEOFFREY
IPC: G07F17/32
Filed: 1983-10-11
Abstract: A fruit machine is adapted for dual control, each player having an operating element. When a stake is inserted, sufficient for a sequence of games, the players play in alternation. Any win is temporarily credited to the player who initiated that play and at the end of the sequence the players may collect their respective winnings, if any. However, certain random events during the sequence, such as a jackpot combination, will trigger intermediate payouts, the distribution to the players then differing from the amounts standing to their credit. For example, the jackpot winner would take not only his own winnings but also those potentially of the other player.
