Inventor: LAPITSKY EVGENY IVANOVICH
IPC: H01L27/082
Filed: 1985-06-14
Abstract: A composite transistor is built on a semiconductor substrate (1) with a common collector (2) and has a plurality of base (3,4) and emitter (5,6) regions forming several transistor stages, the separate base (3,4) and emitter (5,6) regions are arranged uniformly over the surface of the semiconductor substrate (1) and regions of one type in each transistor stage are connected in parallel in a direction from the periphery to the centre of the semiconductor substrate (1) by means of current-supplying contacts (8,9,10). The base regions (3,4) are insulated from one another by the common collector region coming out to the surface of the substrate (1). A mounting contact (13) of the emitter regions (6) is located in the center of the substrate (1), while mounting contacts (14, 15, 16 and 17, Fig. 2) of the base regions (3) are arranged uniformly along the periphery of the surface of the substrate (1). The transistor stages may be connected in a Darlington arrangement. The invention can be used in amplifiers, stabilized power sources, switching circuits, and other control and automatic devices. <IMAGE>

Title: Control of heating units
Inventor: WYMAN PATRICK ROY
IPC: F24C15/10
Filed: 1986-01-03
Abstract: A cooking hob with at least three separate heating devices P, Q, R, e.g in the form of tungsten halogen lamps, has a plurality of triacs 1, 2, 3 each associated with a respective device; a selector circuit 16 controls the operation of the triacs for energising one or a selected combination of devices and a switching means 24, 25 is arranged to connect the devices selectively in series or parallel or partly in series and partly in parallel. The switching means 24, 25 may be electromechanical relays also controlled by the selector 16. When a charge of heat output is demanded by operation of touch pads 17, all the triacs 1, 2, 3 are turned off so that the contacts of relays 24, 25 do not make or break load current. Subsequently the triacs for the new heat level are fired in a soft-start node to reduce surge currents. The relays 24, 25 may be replaced by further triacs arranged to give the same switching actions. <IMAGE>

Patent GB-2194294-A (GB)
Title: Oscillating wind motor
Inventor: HARDCASTLE JOHN MOUTRIE
IPC: F03D5/06
Filed: 1986-08-19
Abstract: A wind motor comprises a cylinder rocked by the action of the wind on sails to generate electricity. The cylinder, sealed both ends, has a shaft through it the ends of which fit through the sides of two floating vessels either end of the cylinder. The cylinder has a heavy keel on one side and masts on the other which penetrate the shaft as they come down to the keel. Spars on the masts run parallel the length of cylinder and support the sails. Bows and sterns of the vessels are connected by booms. From one boom elongate bars rise to rods hanging from the spars each rod holding the lower edge of a respective sail. When wind acts on the sails, the cylinder heels. As the cylinder heels, the bars act on the rods to cause the sails to pivot to a horizontal position so that the wind then passes between them. The weight of the keel then causes the cylinder to rock back to the vertical whereupon the process is repeated. The shaft ends are fitted to chain drive wheels inside each vessel. When the cylinder rocks the wheels partially turn revolving large fly wheels with free wheel hubs to work generators. <IMAGE>

Abstract: To produce blocks having facings of a thermal insulating material, an apparatus comprises an endless conveyor for moving blocks 12 into a moulding assembly which includes an endless chain conveyor 15 having an endless belt conveyor 16 between the chains for supporting the blocks 12. A mould cavity is formed by one face of each block 12, first mould parts 28, each of which is provided at one end of each pair of chain links 20 to extend across the direction of travel of the blocks 12, and second mould parts 34 which are pivotally mounted on the respective chain links 20. In the upper pass common to the chain conveyor 15 and the belt conveyor 16, the mould parts 28 engage with the ends of the block 12 to be faced while the mould parts 34 also are pivoted upwardly into engagement with the sides of the block 12. A liquid foam facing material is fed into the mould cavity which is then closed by the lower pass of a conveyor (17), Figure 1 (not shown). The mould cavity (48) is then kept capped to allow the foam to harden and bond to the surface of the block (12). At the end of the upper pass the mould parts (28) (34) separate to open the mould cavity and enable release of the faced block. <IMAGE>

Title: Treatment of oil effluent
Inventor: WOODMAN GWILYM LESLIE
IPC: B01D17/035
Filed: 1987-05-07
Abstract: A method of splitting a soluble oil effluent, in which the effluent is applied to a coarse separator and then mixed in successive stages with a polyelectrolyte and a coagulant, the resultant flocculated oil/water phase then being treated in a dissolved air flotation unit whereby to separate and recover the oil and water fractions. A coagulating tank may be provided immediately downstream of the mixer stages for the mixture to dwell for a period and a clarifier tank may follow the coagulating tank, again to provide a dwell period for the separating mixture, the floating oil being recovered so as to provide a cleaner/clearer mixture for the dissolved air flotation unit. Oil concentrations of 0.1% to 25% in the effluent may readily be treated from which substantially oil free water (oil level of the order of 0.01%) may be obtained. With further processing, "polishing," this may be reduced again eg to 0.003%. Further, the chemical oxygen demand on the water course with this much cleansed effluent is reduced by a significant factor (about 8) compared with practice hitherto.

Title: Interior article surface layer
Inventor: FURUYA TAMIO
IPC: B32B7/027
Filed: 1989-01-05
Abstract: A surface layer (a) of an interior article (A), comprises a surface layer body (1) formed of a synthetic resin and endowed with high extensibility, and a surface skin (2) formed on the surface layer body and having a softening temperature lower than that of the surface layer body, with an uneven pattern (b) being formed on the surface skin.

Title: Joint for elongate members
Inventor: PLUM DOUG
IPC: F16B7/18
Filed: 1989-02-06
Abstract: A load-support structure of a canopy or like construction has an upright column 1 jointed to a horizontal roof-support member 2. An aluminum alloy block 9 is received within the cavity 5 of member 2 and has a transverse bore 10 and an axial bore 11. Cavity 9b is defined by block 9 in cooperation with wall 5b of member 2 and houses a block 12 having a screw-threaded bore in register with bore 10. Screw 13 penetrates both bores and screws into the bore in block 12. Screw 16 engages in bore 11 and is axially displaceable for adjustment purposes. The head of screw 16 is received in cavity 7 of column 1. Operation of screw 13 displaces block 12 and by reaction causes displacement of block 9 to effect engagement of the head of screw 16 with column 1 in assembly of the structure or disengagement for dissassembly purposes. Relative rotation is prevented by pin 18. <IMAGE>

Title: Internal coatings of a tube
Inventor: ACKERMANN ULRICH
IPC: G02B6/00
Filed: 1989-09-12
Abstract: Process for producing a light waveguide preform by plasma impulse-induced chemical vapour deposition (PICVD process) using glass tubes whereof the internal diameter increases continuously within the coating region in order to compensate for the reduction in coating layer thickness which otherwise would occur as a result of pressure drop along the tube. The decrease in the density of the layer-forming molecules because of the pressure drop can be precisely compensated by an increase, also axial, in the gas volume.

Title: Method for removing cholesterol from eggs
Inventor: CONTE JOSEPH A
IPC: A23L15/00
Filed: 1990-10-03
Abstract: Edible oil containing monoglyceride is emulsified with a mixture of cholesterol-containing egg in aqueous solution. Then, the mixture is heated to a temperature below 70 DEG C and typically is stirred gently to ensure intimate admixture of the oil phase in the aqueous phase. The monoglyceride serves to facilitate oil/lipoprotein interaction in the presence of aqueous phase. The fat in the egg is partitioned into the monoglyceride-containing oil phase. Agitation is continued for a time sufficient to exchange or extract cholesterol and fat from the aqueous phase to the oil phase. The cholesterol- and fat- reduced aqueous phase is the desired low-cholesterol egg product, and is separated from the cholesterol-enriched oil phase. Phase separation may be gravity separation or by centrifugation. Centrifugation may produce three phases, one being a gel-like membrane.
