Title: Automotive hydrostatic transmission
IPC: B60K17/10
Filed: 1981-02-17
Abstract: A self-propelled vehicle, eg a locomotive, has a control unit (13) incorporating a micro processor and a diesel engine (5) driving a pump (11) whose output is varied by unit (13) according to signals representing the speed of the engine and individual where motors (15) and the pressure differential between delivery and return lines (14, 17) which indicates whether the vehicle is pulling or being pushed by its load. The unit (13) compares, the speed of a driven wheel at one side of the vehicle with a reference speed for that side and additionally compares, the speed of a driven wheel at one side of the vehicle with the speed of a driven wheel at the other side, the pump output being increased or decreased should the comparisons indicate speed differences outside allowable tolerances. <IMAGE>

Title: Reciprocating dispensing pumps for soap and the like
Inventor: BANKS STEWART
IPC: A47K5/12
Filed: 1982-04-08
Abstract: A dispenser for liquid soap or a like product includes a slidable valve member (18) mounting a one- way valve (34) and a manually operated plunger (22).

Patent GB-2129343-A (GB)
Title: Pressure diecasting under the action of gaseous pressure medium
Inventor: NIKOLOV IVAN DIMOV
IPC: B22D17/20
Filed: 1982-10-26
Abstract: Communication between a casting mould defined by dies (1 and 2) and an injection chamber (3) is blocked by means of a blocking device (8) which is applied against a seating (31) provided on a runner bush (6) arranged in the fixed die (2) and communicating with the injection chamber (3). During this blocking phase, by opening a valve (27), gaseous pressure medium is introduced into the casting mould up to a predetermined pressure when the valve (27) closes, and the injection chamber (3) is charged with molten casting material from the pourer (18). Thereafter, communication is established between the injection chamber (3) and the casting mould, and the charge of molten material is injected from the injection chamber into the casting mould, whilst maintaining substantially the predetermined pressure of the gaseous pressure medium in the casting mould. After the pourer (18) has charged the injection chamber with molten material, it is moved into a sealed chamber (17) which surrounds the pourer (18) and the inlet to the chamber (3) from the pourer (18) in sealed manner. The gaseous pressure in the casting mould is stabilised, during the injection phase, by bringing the sealed chamber (17) into communication with the casting mould by opening a valve (28). <IMAGE>

Title: Photoconductive detectors with bias
Inventor: ELLIOTT CHARLES THOMAS
IPC: H04N5/374
Filed: 1982-11-30
Abstract: An alternating bias is supplied to a modified photoconductive detector (1) and photosignal extracted from each detector element (2). This extraction may be performed using an integrator (11) to produce dc signal output, or alternatively by using a high-pass filter or phase-sensitive detector to extract photosignal at an harmonic of the bias frequency. The detector (1) used is provided with elements (2) that have a responsivity that is a different function of bias amplitude for each polarity. The detector element (2) may be shaped with variation in width or depth, to produce this differential responsivity. Alternatively element bias contacts (3, 5) may be of different width to produce field gradient and differential responsivity. It is advantageous to obscure a part of each element area (2) by including an opaque mask. <IMAGE>

Patent GB-2141284-A (GB)
Title: Synchronising tape recorders
Inventor: BANWELL NIGEL EDWARD
IPC: G11B27/029
Filed: 1984-04-11
Abstract: Two or more multi-track tape recorders are synchronized so as to allow all the audio tracks to be replayed and mixed together as though they had been recorded on one large multi-track tape recorder. The signals that are recorded to achieve such synchronization can be combined with the audio signals for one track and thus do not require the exclusive use of one track on each tape recorder. Synchronization can be established by either of two methods.   1/From the start only, if a wideband audio signal is required to be used on the same track as the synchronizing signal. 2/ From preset points if the audio signal that is required to be used on the same track as the synchronizing signal can be restricted in bandwidth or time.   A facility can, by removing all except the first marker point, combine the advantages of the two methods. <IMAGE>

Patent GB-2156878-A (GB)
Title: Encoding and transmission system for mud pulse telemetry of tool face angle data
Inventor: ROESLER RICHARD FREDERICK
IPC: E21B47/18
Filed: 1985-02-22
Abstract: Orthogonal indicia of orientation of a drilling tool 22 at the end of a drill string 18 within a borehole 12 are measured by a pair of sensors at intervals of a first frequency. Pressure pulses indicative of the tool face angle are generated in the mud flow passing along the drill string 18 by means of a mud flow valve in response to each measurement, and the pressure pulses are sensed at the surface in the vicinity of the well head 28 so that the tool face angle data can be obtained and used by the drilling operator. When the drilling tool 22 requires rapid reorientation following the addition of a section of drill pipe to the drill string 18, the reduction in the pressure of the mud flow due to the interruption of the mud flow necessitated by such addition is sensed by a mud pressure sensor. The sensor in turn provides a transmission rate selector signal which changes the interval of tool face angle measurement from the first frequency to a second, higher frequency, with the result that a more rapid updating of tool face angle is possible for reorientating the drilling tool 22 following addition of a drill pipe section. <IMAGE>
