Title: Rotor and stator assembly for a gas turbine engine
Inventor: MORITZ ROBERT RUDOLPH
IPC: F01D11/00
Filed: 1980-11-11
Abstract: A rotor and stator assembly, particularly the turbine rotor (14, 17) and nozzle guide vane (30) assembly, of a gas turbine engine in which the inner platforms (29) of the vanes are provided with passageways (41, 43) into which is deflected radially outward flows (45, 46) from the face of the adjacent rotor discs (15, 18). Deflector means (24, 34) provide the necessary deflection. The passageways are shaped so as to convey the flow of air into the main gas flow of the engine with a minimum amount of disturbance, thus reducing the losses caused by these flows. <IMAGE>

Title: Method and equipment for treating chopped crops
IPC: B07B11/00
Filed: 1981-01-13
Abstract: In the treatment of chopped crops containing a mixture of grains or other seed, such as peas, beans, etc., and other plant components, the goods are introduced into a separating section (7) through which air flows, in a rotating drum, the temperature of the air entering a preliminary drier (6) being regulated (47... 50) so that the superficial moisture of the goods is mainly removed before the goods are introduced into the separating section, as a result of which the grains can be removed without being damaged by prolonged overheating. The preliminary drier and the separating section consists of an integrated, rotating drum. Round the shell of the drum there are discharge openings (33) for the grains, and in the separating section there are members (80) (Figs. 3, 4) for feeding the grains back towards the grain discharge openings to the extent that they have passed the openings (33) without being discharged. Alternatively a plurality of openings around the drum may be replaced by one continuous opening around the drum. Furthermore there are entrainment means for lifting up straw particles in the drum so that the separating work is facilitated. In the front end of the drum there is a discharge opening (83) for the straw particles. <IMAGE>

Title: Articles of furniture
IPC: A47C4/10
Filed: 1981-04-16
Abstract: A bench seat comprises a slatted wooden seat portion 10 having adjacent opposite ends thereof metal legs 13 pivotally mounted on the seat portion so that they may be swung between a folded position, where they lie along the seat portion, and an extended position where they extend away from the seat portion.

Its ends are slideable through slots 23 in cross bars 15 of the legs, the slots being so shaped as to permit the swinging movement of the legs between the folded and extended positions. Bent- over ends 22 of the tension member 21 act as stops to limit outward deflection of the legs. The tension member may be flexible (i.e. a rope or like). <IMAGE>
Patent GB-2078971-A (GB)
Title: Liquid metal level measurement
IPC: G01F23/26
Filed: 1981-06-17
Abstract: In order to measure the level 2 of an electrically conductive liquid, such as molten sodium, contained in a tank 1 of non-magnetic material, such as stainless steel, a pair of induction elements 7a, are secured to the outside of the tank at its upper and lower extremities. Moveable carriage 4, fixed to a track 3, carries two more induction elements 7b which form complementary elements to elements 7a in two a.c. bridge networks 5,6. Whenever the level 2 alters so that it no longer lies between the positions of the elements 7b, causing one inductive path to comprise two media, the differential of the outputs of the two bridges causes a control means 8 to actuate a servomotor to move carriage 4 until each inductive path comprises only one medium again and the differential output is nulled. The liquid level can then be read off of a scale on the track, in addition to electronically. <IMAGE>

Title: Industrial fabrics
Inventor: HALL KAREN
IPC: D06M11/82
Filed: 1981-07-06
Abstract: Fabrics for industrial purposes, and more especially for use as grout bags in areas of fire hazard, such as coal mines, comprise plain woven fabrics composed of textured continuous filament synthetic yarns in both warp and weft. With from 40 to 380 ends and 40 to 380 picks per dm and with yarns of 110 to 2200 dtex, the fabrics have a structure close enough to retain cementitious aggregates while allowing surplus water to drain away. A finish comprising a synergistic combination of a brominated aromatic compound and a metal borate salt in a wash- resistant polymeric binder ensures water-resistant flame-retardant properties. For use in coal mines, the fabric may contain epithropic fibres or the finish may contain conductive carbon.

Title: Electroless plating of nickel onto silicon
Inventor: GONSIORAWSKI RONALD
IPC: C23C18/16
Filed: 1981-10-21
Abstract: A method for electrolessly plating nickel onto silicon which renders unnecessary any catalyzing pretreatment comprises the immersion of a silicon substrate in a nickel chloride bath containing a fluoride e.g. ammonium fluoride or hydrogen fluoride. The coated product may subsequently be heated in an atmosphere of H2 to form an ohmic contact at the Ni/Si interface. Ni is selectively deposited in regions of the substrate not covered with silicon oxides. The method is especially advantageous in plating nickel onto silicon shallow junction devices for use as photovoltaic solar cells. An intermediate layer of aluminium may be provided as a backing on the rear of a solar cell. <IMAGE>

Title: Joining electric cables
Inventor: HEAD JULIAN GORDON
IPC: H02G15/196
Filed: 1981-10-29
Abstract: In forming a joint between two electric cables having elastomeric or thermoplastic insulations 1, 2, a screen 5 is formed by applying semi-conducting tapes and then a thin insulation layer 6 is formed over the screen before a insulation 7 of thermoplastics or cross-linkable thermoplastics tapes is applied. The material of the thin insulation layer 6 is sufficiently soft and deformable so as substantially to cushion the screen 5 against deformation by the tapes of the main insulation layer (which deformation might cause electrical breakdown). <IMAGE>

Patent GB-2119623-A (GB)
Title: Process of manufacturing a steak or schnitzel product
Inventor: HOUGHTON DAVID
IPC: A23L13/00
Filed: 1982-05-04
Abstract: The product is made by mechanically or chemically tenderising selected meat muscle, pressing the tenderised muscle in a mould or clamp to produce a flattened and elongated meat joint, which may be regular or irregular in shape and slicing. Tenderising is preferably effected by "shredding" and may be followed by freezing and conditioning the meat to -2 to -15 DEG C prior to pressing. Pressing may be effected by hydraulically pressing the meat in a die to give products of varying thickness and constant plan area. Alternatively the meat is treated as above, but not pressed to the final thickness - it is left thicker. This fixed area shape is then pressed between two flat plates to a constant thickness allowing the meat to 'flow' to whatever natural shape it wishes to assume.
