Patent GB-2077407-A (GB)
Title: Heat pump
IPC: F25D21/02
Filed: 1981-05-15
Abstract: The heat pump provides a connection (11) for ducting hot refrigerant gas from an expeller (1) directly to an evaporator (4) of the pump under the control of a solenoid valve (12) and a throttle (13). The evaporator is equipped with an icing sensor (16) which on sensing a, predetermined degree of icing of the evaporator opens the solenoid valve to permit gas to enter the evaporator through the throttle to effect de-icing. The consequent rise in pressure in the evaporator shuts off an expansion valve (5) through which condensate from a condenser (2) of the pump is normally fed to the evaporator. <IMAGE>
Patent GB-2080451-A (GB)
Title: Transmission control systems
IPC: F16H59/30
Filed: 1981-07-14
Abstract: A control system for an automatic transmission for a motor vehicle comprises means for comparing electrical signals related to vehicle velocity and to engine air intake vacuum or throttle opening and for producing a transmission shift control signal. The velocity signals may be produced by a rotary magnet system causing opening and closing of a reed switch connected to a frequency-to-voltage converter. Engine intake vacuum may be detected by vacuum responsive switches and converted stepwise into voltage signals which, with the velocity signals, are fed to a comparator whose output controls a shift valve and also provides positive feedback to the vacuum-responsive signal-forming circuit to cause upshift/downshift hysteresis. <IMAGE>

Title: Railway car coupler having an improved thrower
IPC: B61G3/04
Filed: 1982-01-13
Abstract: A railway car coupler is disclosed as having a knuckle thrower 10 with an improved blunted tip 16, as distinguished from the more pointed tip of a conventional AAR Standard thrower for either an E or F-type coupler. The improved tip causes an increase in the moment arm of the knuckle as the knuckle is rotated by the thrower from a closed to an open position. The invention is particularly applicable to an F-type coupler. <IMAGE>

Title: Injection system for an internal combustion engine
Inventor: PFEIFLE HELMUT
IPC: F02M61/20
Filed: 1984-05-17
Abstract: An injection quantity metering device (3) meters fuel to a pumping nozzle (4) for pumping and injection into the combustion chamber of an internal combustion engine. The pumping nozzle (4) has a pump cylinder (8), a main piston (9) which enters the pump cylinder and is driven by a cam (62), and an auxiliary piston (10) which is displaceable within the pump cylinder (8) and defines a pump working chamber (8a). The pump cylinder (8) surrounds between the main piston (9) and the auxiliary piston (10) a compensating chamber (74) which serves to receive a liquid column of adjustable length, the said column driving the auxiliary piston (10) during downward movement of the main piston (9) during the injection operation. The injection operation only takes place when a control port (48) disposed in the main piston (9) and communicating with the compensating chamber (74) is closed by means of a hydraulically adjustable control sleeve (49). The commencement of injection can be advanced or retarded by varying the adjusting pressure acting upon the control sleeve (49). <IMAGE>

Title: Improvements in and relating to liquid chromatography
Inventor: TRAFFORD PAUL FRANKLIN
IPC: B01D15/08
Filed: 1984-07-05
Abstract: In a process of liquid mixing, more especially for use in mixing the solvents of an eluent for liquid chromatography, the liquids are supplied from separate reservoirs (1-4) to a common conduit (13) via fluid flow control valves (5-8). Predetermined pressure drops are maintained across each valve by arranging appropriate pressures in the reservoirs (1-4) and the conduit (13). The rate of flow of each liquid is determined by setting each valve (5-8) to present a predetermined flow resistance calculated from the formula   <IMAGE> where L = the flow resistance of the valve  DELTA H = the pressure drop across the valve S = the specific gravity of the liquid and I = the desired rate of flow of the liquid. The calculation and automatic actuation of the valves is effected by an electronic control (14) incorporating a microprocessor which may be programmed to vary the liquid mixture with time to provide a desired elution gradient. <IMAGE>

Patent GB-2154249-A (GB)
Title: Cathode sputtering
Inventor: GOERKE KLAUS
IPC: C23C14/34
Filed: 1985-02-04
Abstract: The bond strength and bond reliability between the cleaned and roughened surface of the carrier layer and the layer sputtered onto it as well as the bond strength and bond reliability also between layers sputtered onto one another in succession are considerably improved by the targets used for sputtering-on the layers being cleaned, i.e., free-sputtered by cathode sputtering against a shield over the surface to be eroded, and by a reverse sputtering from the surface to be coated prior to sputtering-on of the surface layer or layers. The reverse sputtering from the surface to be coated is to be carried out not only as far as cleaning but as far as perceptible roughening of the surface to be coated on the carrier layer, that is, after the style of an etching. The time between the conclusion of this etching and the start of the sputtering-on of the desired surface layer is to be kept so short that no surface contamination occurs. in like manner successive sputterings-on of further layers are to follow at such short intervals that no surface contamination can arise.
