Title: Control for a load-dependently operating variable displacement pump
Inventor: KAUSS WOLFGANG
IPC: C01B3/50
Filed: 1990-04-25
Abstract: An electrohydraulic control for a load-dependently operating variable displacement pump (2) is equipped with a differential pressure control device (30) for ensuring a predetermined pressure drop at the control edge of a directional valve (60) integrated into the consumer supply line. The differential pressure control device comprises a servo valve, the valve spool of which is moved between first and second positions by pump output pressure against the compressive force of a spring (26) and of a control pressure led off from the supply pressure downstream of the directional valve (60). Variations in the pump output pressure and the control pressure operate the device (30) which in turn adjusts the pump (2). In order to be able to adapt the volume flow control to the different requirements of various consumers, the control pressure effective at the servo valve (30) is arbitrarily influenced by means of a separately controllable actuating device (100). <IMAGE>

Title: A method of testing the damping of a rotary member
Inventor: PHAROAH PETER LEONARD GEORGE
IPC: G01P21/02
Filed: 1990-06-06
Abstract: A rotary member (4) carries a magnet and can rotate in a mounting (1); working coils will later be wound on the mounting to form an electromagnetic device. The damping of the rotary member (4) is tested by bringing the mounting (1) adjacent a coil (9) to which a pulse is applied. The resultant field interacts with that of the magnet and the member (4) is rotated. The rotating field from the magnet induces a response in another adjacent coil (10) or in the same coil (9) and the decay of that response, which is an indication of the damping, can be observed or otherwise monitored. The invention is described in relation to crossed-coil instruments such as speedometers, tachometers and fuel gauges, and enables damping by fluid in the mounting (1) to be assessed prior to the winding of the instrument coils. <IMAGE>

Title: Improvements in and relating to vehicle trim strips having remoulded ends and methods and apparatus for forming them
Inventor: CAKMAKCI MEHMET Y
IPC: B29C67/00
Filed: 1990-08-10
Abstract: A decorative trim strip is made by compression reshaping of an end of a previously extruded length of thermoplastic material (20) eg of P.V.C. The decorative surface (24) of the length intended for viewing is maintained during the compression moulding at a temperature well below the softening point of the thermoplastic material by cooling of the lower mould (30) which defines the reshaped end, the opposite surface intended for fixing to the vehicle being maintained above the softening point, by heating of the upper mould section (50). The process ensures that the decorative surface extends around all of the reshaped end, to the plane of the fixing surface, thereby avoiding viewing exposure of a cut end of the strip. The heated mould part section (50) may mould a fixing stud (73) onto the strip. The strip material may be P.V.C., may comprise a foam interior, and the decorative surface may comprise a co-extruded layer, or a decorative and an outer transparent P.V.C. protective strip, applied after extrusion before the reshaping. <IMAGE>

Title: Anti-theft exhaust path closure devices.
Inventor: WYGNANSKI WLADYSLAW
IPC: B60R25/043
Filed: 1992-10-07
Abstract: Apparatus for immobilising an internal combustion engine in a land, water or airborn vehicle in which a closure device is located in the exhaust of the engine, within or downstream of the exhaust manifold which is movable into a blocking position in which the passage of exhaust gases from the engine is at least substantiallly prevented in response to the increase in pressure or temperature of the exhaust gases due to the running of the engine. The engine will thus start normally, if cold, and run normally until the exhaust gases cause the closure device to block the exhaust whereupon the engine will lose power and stop. A first device is provided which responds to an increase in pressure or temperature in the exhaust of the engine to move the closure device into its blocking mode and a second device is provided which counteracts the movement of the said first device in response to the vacuum generated at the vehicle inlet manifold. By providing an interlock mechanism, operable only by an authorised user of the vehicle, which mechanism prevents the vacuum from acting on the second device, unauthorised use of the vehicle will result in the engine starting but thereafter only running for a short time until the closure device moves to block the engine exhaust.

Title: Producing a surface coating of nitrogenous alloy
Inventor: JAEGER DAVID MARTIN
IPC: C23C4/12
Filed: 1993-01-11
Abstract: A method of forming a layer of a nitrogenous alloy upon a substrate body includes the operation of depositing upon the substrate particles of a powder including an alloy containing a nitride-forming material and a thermally decomposable nitrogen donor material and heating the particles to a temperature such that the nitrogen donor dissociates to provide free nitrogen which reacts with the nitride former to form a nitrogenous alloy prior to the deposition of the particles to form an adherent non-porous layer of nitrogenous alloy upon the substrate. The concentration of the nitrogen donor may be such that free nitrogen exists in the deposited layer and this diffuses into the substrate to provide a nitrogenous interfacial region of the substrate. The deposited layer may be subjected to a hot densification process, eg using hot isostatic pressing. The nitrogen donor may be chromium nitride and the nitride former may be titanium or an MCrAlY alloy (M being Fe, Co, Ni). A dispersant may be included in the particles or introduced into the surface alloy layer and may be titanium nitride itself. The particles are either formed by atomisation of a molten liquid precursor material or by the use of flame or plasma spraying.
