Patent GB-2102496-A (GB)
Title: Flow control device
Inventor: KINNERSLY RICHARD FURNEAUX
IPC: F01P1/04
Filed: 1981-06-18
Abstract: A flow control device, for example for an internal combustion engine, for controlling the flow of petroleum fuel into the engine, comprises regulator elements (18, 19), the relative positions between which controlling the flow rate, the positions of the regulator elements being controlled by an input element (23). The device comprises an adjustment means (30) which can be set to a number of different values, which provide for different response rates of the regulator elements (18, 19) to movement of the input element (23). Liquid fuel is thus injected at a desired rate into a stream of air, utilising a closure member (66) which when the pressure at which fuel is delivered to an outlet nozzle is less than a predetermined value, prevents flow of fuel through the outlet nozzle, and when the pressure at which fuel is delivered the outlet nozzle exceeds said predetermined value, the closure member moves to open the outlet a distance proportional to the pressure in the outlet nozzle. <IMAGE>
Patent GB-2086297-A (GB)
Title: Method of Forming a Wire Bond
IPC: H01L21/60
Filed: 1981-10-26
Abstract: A wire (6) made of aluminium or an aluminium alloy is passed through a capillary (5) and a first spark discharge is produced in a protective gas atmosphere between two auxiliary electrodes (12, 13). As a result of this the protective gas is ionised to form a plasma having such a low resistance that a spark discharge takes place between an electrode (11) and the wire (6) at a voltage of between 25V and 200V. Thus a ball is formed at the end of the wire which is then bonded between an electronic microcircuit (17) and a contact area (18) using the capillary. <IMAGE>

Title: Apparatus for examining materials
IPC: G01N23/08
Filed: 1981-12-16
Abstract: An apparatus for determining the composition of a mixture of materials 25 (such as stone and coal) travelling on a conveyor belt 23 comprises an x-ray tube 1 arranged to produce a succession of pulses, the spectral composition of each of which varies with time in a predetermined manner, and a plurality of current mode radiation detectors 27 arranged to receive radiation from the tube after passage through the material to be examined. According to a second aspect the apparatus comprises two x-ray tubes which alternately produce pulses of a different spectral composition, at least one current mode radiation detector receiving radiation from one of the tubes after passage through the material to be examined. As the attenuation of x-rays by a mass of material depends upon the spectral composition of the x-rays as well as the mass and composition of the material, the form of the signal derived from the detector or detectors gives information about the composition of the mixture of materials. <IMAGE>

Title: Peg board game
Inventor: MILEWSKI MANUEL
IPC: A63F9/00
Filed: 1982-01-20
Abstract: Apparatus for playing a game comprises four blue and four green pegs for each of two players and a board having a central hub and outer ring with a rotatable surface therebetween, the surface bearing green lines intersecting blue circles with a peg-receiving hole at each intersection, the green pegs being moved on the green lines and the blue pegs on the blue circles either individually or in "sequences". The surface also bears red and yellow start lines for receiving each player's eight pegs, an orange eye-like pattern that allows green pegs to move freely but prevents the "sequences" from doing so, and orange "hindrances" at each quarter. The hub and outer ring each have red and yellow spans defining respective playing areas and the aim of the game is to revolve one's start line clockwise employing blue "sequences" through a circuit back into one's play area or alternatively to "take" certain of one's opponent's pegs. <IMAGE>

Patent GB-2101453-A (GB)
Title: Radio communications link
Inventor: GIBBONS PAUL L W
IPC: H04B7/005
Filed: 1982-03-11
Abstract: This invention relates to communications where multipath reception is expected. A transmitter (10) and a receiver (11) are synchronously switched between a Training mode and a Traffic mode by reference clocks (18, 21). In Training mode the reception pattern of the communications link is established by measuring the time delays in multiple reception of a transmitted pulse. In the Traffic mode, window waveforms enable gates (25, 26, 27) in accordance with the reception pattern so that multiple receptions of a transmitted pulse may be combined (28). By providing overlaid waveforms for each transmitted pulse, the problem of limiting transmission repetition rate to the time delay of the longest transmission path is overcome. <IMAGE>

Title: Cooled aerofoil for a gas turbine engine
Inventor: LINGS BARRY WILLIAM
IPC: F01D5/18
Filed: 1982-06-29
Abstract: A cooled aerofoil, such as the aerofoil of a nozzle guide vane, for a gas turbine engine has a cooling system in which the release of cooling fluid on the convex suction flank is avoided. The cooling system utilises a thin skin 28 which overlays the contoured surface 27 of the convex flank to form a plurality of passageways. A first flow of cooling fluid enters these passages via a plurality of impingement holes 30 and leaves via cross flow passages 31 and 32. The cross flow passages allow the fluid to pass to the opposed, pressure flank of the aerofoil where it leaves the aerofoil via film cooling holes 37. <IMAGE>
