Abstract: A mine roof support comprises front hydraulic props (14) between a base section and a canopy, and rear hydraulic props (15) between the base section and either the canopy or a shield section. First valves (22 to 24) connect the front and rear props to a first source (SP) of hydraulic fluid to extend the first and second props and raise the canopy relative to the base section. Second valves (25, 26) are responsive to the hydraulic fluid pressure in the front and the rear props to provide a constant supply of hydraulic fluid from a second hydraulic fluid source (HP) to the front props (14) once the hydraulic pressures in the front and the rear props exceed a first predetermined value or values, the second hydraulic fluid source being at a greater pressure than the first hydraulic fluid source. A third valve (27) provides a constant supply of hydraulic fluid from the first or second hydraulic fluid source to the rear props (15) once the hydraulic pressures in the front and rear props exceed a second predetermined value or values not less than the first predetermined value or values. <IMAGE>

Title: Water bath air filter
Inventor: MACDONALD CAMERON
IPC: F24F8/133
Filed: 1992-06-17
Abstract: A water bath air filter has a water bath filtration bowl (11) which is demountable so that it can be filled with water and also emptied and cleaned by the user quite easily. It is mounted on top of the power unit (10) which is designed to draw air through the suction tube (13). This tube is placed inside the fluted suction tube of the water bath filtration bowl (14) and the two are sealed together by a rubber seal (26) which is situated around the base of the power unit suction tube (13). When the unit is switched on a fan draws air in through the connected suction tubes (13 and 14) thus lowering the air pressure in the air filtration bowl cavity (26). This drop in pressure causes air to be drawn in through the water from outside of the air filtration bowl (17). This air is cleaned by the fact that if anything in the air is soluble in water it would be dissolved, anything heavier than water would sink, and anything else would be trapped by the water's natural surface tension. Bubbles which pass through the water are diffused by some baffles placed in the top of the unit, this prevents splashes of water from entering into the suction tube (14) and into the suction chamber of the power unit Air is expelled through vents placed around the suction chamber opposite and adjacent to the suction fan blades. <IMAGE>

Title: Automatic frequency control
Inventor: BAECKSTROEM TOMAS O
IPC: H03J7/02
Filed: 1992-10-07
Abstract: A radio-frequency receiver employing antenna diversity is provided with a plurality of antennas 11, 13 and a local oscillator 33. Individual error signals are derived from each of respective ones of signals received from the plurality of antennas. The error signals are thereafter combined at 29 in such a way as to arrive at a combined error signal having greater reliability than any one of the individual error signals taken alone. Finally, an automatic frequency control circuit 31 is controlled using the combined error signal. Since the effect of fading on the input signal to the automatic frequency control circuit is reduced, performance of the automatic frequency control circuit is increased and the quality of radio reception is improved. The received signal may be modulated by digital data e.g. differential phase shift keying and the circuit 23 also produces the detected data. <IMAGE>

Title: Substrate regenerating biosensor
Inventor: HILL NORMAN
IPC: C12Q1/00
Filed: 1992-10-16
Abstract: A biosensor for the detection and determination of the concentration of toxins by use of enzyme inhibition. Inhibition biosensors are affected by non-specific denaturation and substrate utilisation which both result in a limited operational lifetime. These problems are mitigated by providing in an environment an enzyme which is oxidised by hydrogen peroxide the oxidised enzyme being reduced by an electron transfer agent, such as ferrocene, which is itself oxidised in the process. The electron transfer agent is capable of regeneration back to the reduced state and the extend of electron transfer regeneration gives a measure of enzyme inhibition by toxin. Electro-chemical technique allows for the generation of hydrogen peroxide from oxygen in aqueous media and the reduction of oxidised electron transfer agent.  Immobilisation of the enzyme to an electrode increases efficiency whilst potentially reducing denaturation. The biosensor can be used for the environmental determination of toxins like cyanide.

Title: Security device
Inventor: MAGEE JOHN
IPC: E05B65/36
Filed: 1992-10-30
Abstract: The security device comprises a casing 80 which may be secured to a door of, for example, a vehicle. Part 2, on which are rotatably mounted three hexagonal discs 18, co-operates with the casing. At one end, the part 2 includes a locking bolt 10 arranged to co-operate with a bolt socket 88. End 30 of the part 2 is arranged to actuate a master switch which controls the supply of current to, for example, the vehicle's fuse box. When the discs 18 display the correct numerical combination, the locking bolt 10 can be moved relative to the casing, secured in the bolt socket 88 and then the discs scrambled in order to lock the door in position. Also, when in this position, the part 2 actuates the master switch in order to cut off the supply of current to the fuse box. Accordingly, the fused circuits of the vehicle are disabled. The door may be opened by arranging discs 18 so that part 2 can be retracted from socket 88. During the movement of the part 2, end 30 of part 2 actuates the master switch which, in turn, reconnects current supply to the fuse box. <IMAGE>

Filed: 1992-12-30
Abstract: A reversible heat pump for use as an air conditioner operable in a cooling mode and a heating mode includes a first external heat exchanger (4) which works as a condenser in the cooling mode and a second external heat-exchanger (13) which works as an evaporator in the heating mode. Bypass means (22) having a capillary (23) is disposed between a discharge side of a compressor and a point between an expansion valve (5) and the second external heat-exchanger (13). The expansion valve (5) is connected between an inner heat-exchanger (7), which works as a condenser in the heating mode, and the first and second external heat-exchangers. A two-way control valve (16) prevents refrigerant from flowing to the second external heat-exchanger in the cooling mode. In the heating mode, the second heat exchanger (13) is heated by heating means (14). Upon a malfunction, during heating, the pressure of the refrigerant which is trapped between the control valve (16) and the expansion valve (5) increases until the pressure exceeds the pressure of refrigerant discharged from the compressor. At which time the refrigerant is released into the bypass means (22). <IMAGE>
