Patent GB-2078358-A (GB)
Title: A cooling tower and a method for the stabilisation of the boundary flow in the cooling tower
IPC: F28F25/12
Filed: 1981-06-12
Abstract: A cooling tower has a wall (1) defining a cooling air flow passage which reduces in cross-section along the direction of air flow towards a neck region (2) and then widens again. A body (3) is mounted on the wall in the neck region (2) to direct air from a central portion of the passage to a radially outer portion of the passage. In this way energy rich air from a region in the passage substantially uneffected by wall friction is injected into the energy-poor air in the boundary layer in the vicinity of the neck region. This helps to avoid boundary layer separation and thereby maintain the cooling efficiency of the tower which would otherwise be reduced. <IMAGE>

Title: Failsafe operation of hydraulic brake pressure booster
IPC: B60T8/34
Filed: 1981-09-15
Abstract: A boost-pressure responsive valve (shown in its failsafe position) connects a boost chamber 10 to the brakes when pressure source 14 is intact and also connects master cylinder pressure chambers 20, 23 to a pressure-limiting valve 32 whose limit pressure is set by pedal force transmitted via spring 31. Chambers 20, 23 thereby function as hydraulic force simulators in concert with spring 31. On failure of pressure source 14 (as shown), the valve 35 connects the master cylinder pressure chambers 20, 23 to the brakes and isolates them from valve 32; the valve also isolates the boost chamber 10 from the brakes. Failure of the master cylinder piston seals 22, 25 is detected even during normal (boosted) operation by the collapse of pressure in the master cylinders and resultant pedal movement. Valves 41, 46, 49 are responsive to wheel slip control signals. <IMAGE>

Title: Refrigerator
IPC: F04B49/06
Filed: 1982-03-18
Abstract: A refrigerator comprises a motor- compressor unit (16) having a definite rated power and piston displacement but arranged to operate with different performance characteristics which, in a conventional system, would require different rated power and piston displacement values. This is achieved by varying both the frequency and voltage fed by a variable electrical power supply (26) to the electric motor of the unit (16), the value of the supplied power at any given time being determined by an electronic control system (24) processing temperature data determined by sensors (18, 20, 22) in the refrigerator. As shown the sensors are respectively in the refrigerator cabinet (10), on the evaporator (12), and on the condenser (14). The control system (24) includes a microprocessor and keeps the ratio V/f of the motor supply constant. The system may be used to maximise efficiency by giving the lowest possible condenser temperature and the highest possible evaporator temperature, or to keep the sensed temperatures constant. <IMAGE>
