Title: Multi-ratio gearbox
Inventor: ASHFIELD ROBERT ANDREW
IPC: F16H3/095
Filed: 1983-01-05
Abstract: In a multi-ratio gearbox, for vehicles, having two contemporaneously operative layshafts, the sharing of the torque in equal or predeterminedly unequal proportions between the layshafts is achieved by interposing a suitable differential unit 31 between an input shaft 30 and the layshafts 32, 33. Where each of a plurality of gears 35, 36 and 37 fixed to an output shaft 34 meshes with two identical gears 38 and 39, 40 and 41 or 42 and 43 rotateable on and individually clutchable to the respective layshafts 32 and 33, the overall gear ratios are arranged in a geometric progression by arranging that the layshaft to output shaft gear ratios are arranged in the square of the common ratio of said progression, that the layshafts' clutch operating sequence connects the output shaft 34 contemporaneously either to both layshafts 32 and 33 through any one of the output shaft's gears 35, 36 and 37 or to the respective layshafts 32 and 33 through any two of said gears which are consecutively sized, and that the differential unit 31 shares the torque between the layshafts 32 and 33 in said common ratio. The gearing on the respective layshafts 31, 32 may be different such that the torque is shared equally between the layshafts. <IMAGE>

Title: Control of a central heating system
Inventor: DANN ROYSTON GEORGE
IPC: F24D19/10
Filed: 1983-12-19
Abstract: A control unit includes a cylinder thermostat 16, a room thermostat 17 and two pipe thermostats 18 and 19. The thermostat 18 is mounted on the pipework in the space heating branch 6 downstream of the radiators 8 and the thermostat 19 is mounted on the pipework in the hot water branch 7 upstream of the cylinder 9. When both hot water and space heating are required the boiler is operated and hot water is directed by the valve 4 to flow into the space heating branoh 6 until the water reaches a preset level at the point where the thermostat 18 is mounted. At this stage the thermostat 18 switches from position e to f and the valve 4 directs the water to flow into the hot water branch 7. When the water temperature reaches a higher preset level at the point where the thermostat 19 is mounted it switches from position g to h. If thermostat 18 has switched back to position e because the temperature of the water at the thermostat 18 has fallen to below its preset level, the valve 4 directs the water to flow into the branch 6. The process is then repeated. <IMAGE>

Title: Apparatus for Opening a Sealed Container
Inventor: DIKE GORDON WILLIAM ROSS
IPC: B65B69/00
Filed: 1984-03-09
Abstract: A sealed container (10) containing e.g. frozen blood plasma is opened by locating it, using holding means (16, 22), in a predetermined position inside a protective screen (42), inserting into it a hollow needle (32), and then injecting through the needle a quantity of high pressure fluid, e.g. nitrogen, into the container (10) which is thereby split open to allow the frozen contents to fall into a collecting receptacle. The protective screen (42) cannot be opened during the splitting operation. The object of this is to contain any particles of the frozen contents which might otherwise spread infection, and conversely to prevent infection reaching the contents from outside. The air inside the screen (42) is continuously extracted and any solid or liquid matter carried over is held by a filter (80) or incinerated before the extracted air is discharged to atmosphere. <IMAGE>

Title: Circuit for ensuring correct connection of load to three phase supply
Inventor: BAX ANTON MARCEL
IPC: G01R29/18
Filed: 1985-11-28
Abstract: The circuit 3 is connected between a three phase power supply 1 and a load 2, particularly a motor, and ensures the correct application of phase signals to the motor, regardless of the way in which the control circuit is connected to the power supply. A first output A of the supply is connected directly to an input 21 of the motor via the circuit 3. Supply of power to the other two inputs 22,23 is controlled by four switches, two of which 41,42 are connected to the supply second output 12 and to output to respective motor inputs 22,23, and the other two switches 43,44 are connected to the supply third output 13 and to respective motor inputs 22,23. The switches are controlled such that switches 42,43 are on, and switches 41,44 are off if the third output signal C is positive with respect to the first output signal A when the second signal B passes through zero with respect to the first output signal A in a positive sense. Similar switches 41,44 are on and switches42,43 are off if the third signal C is positive with respect to the first signal A when the second signal B passes through zero with respect to the first signal A in a negative sense. The arrangement may be applied to a motor driving a gyroscope, the circuit 3 being mounted inside the motor casing as a factory-assembled unit. <IMAGE>

The patterns are shown in the zero position in which a peak signal of magnitude 6 is obtained, Fig. 7b shows the change in signal, for example light transmitted by slots forming the elements of the pattern, as the relative position of disc and mask changes. With four three-element patterns as shown the spacing between successive patterns increases from 3 to 5 to 8. The second and fourth patterns are the reverse of the identical first and third patterns. <IMAGE>
Patent GB-2171791-A (GB)
Title: Heating and ventilating system
Inventor: CROLLA GERALD VINCENT PAUL
IPC: F23N5/24
Filed: 1986-02-28
Abstract: A heating and ventilating system especially for buildings such as churches which require infrequent, short term heating, comprises ducting 1 extending from an inlet 3 arranged to receive air from outside the building to an outlet 4 arranged to deliver air into the building. A fan 5 in the ducting supplies air to a burner 6 in the ducting which heats the air passing to the outlet via a sound attenuator 8. A control system regulates the heat output of the burner by reducing the fuel supply to the burner when the temperature is below a pre-set value, thereby reducing thermal shock caused by heating the building too rapidly. <IMAGE>

Patent GB-2181010-A (GB)
Title: Infrared imaging devices
Inventor: BAKER IAN MARTIN
IPC: H04N5/33
Filed: 1986-09-10
Abstract: In an infrared imaging device, photocurrent generated by detector elements 1, e.g. cadmium mercury telluride photodiodes, is integrated in resettable capacitors 2, and an output signal S is derived by reading the potential of the capacitor 2 at the end of its integration period, e.g. using a source-follower MOST 3. In accordance with the invention, the addressing and switching means 6, 7 of the device sequentially couples each capacitor 2 to a common reading means 3, and a common reset means 5 resets sequentially the reference voltage level at each capacitor 2 and at the common voltage-reading means 3. This avoids non-uniformities in detector element signal processing and measurement which can arise with each capacitor 2 having individual voltage reading means and reset means. It also provides a compact cell structure and suitable circuit configuration for enhancing the device performance, for example by adding blooming-protection means 11 and/or an expanded capacitor arrangement for increasing or varying the integration capacity and/or for providing alternatively switchable integration means for each detector element 1, and/or for interfacing with a 2-d switched array of detector elements 1. Preferably, a shift register 6 with a source of clock voltage pulses 24 is used for the addressing, the falling edge of each pulse 24 being used to clock the shift register 6 and the rising edge of each pulse 24 being used to trigger the reset gate 5. <IMAGE>

Title: Liquid level monitor
Inventor: WILLIAMS ROY
IPC: F16N19/00
Filed: 1986-12-02
Abstract: A liquid level monitor includes a probed which has a flexible membrane 8 secured over its lower end. The membrane 8 contains an oil or spirit 12 and the specific gravities of membrane 8 and the oil 12 are such that when the level of a liquid 13 to be monitored rises the membrane 8 floats on the liquid 13 to bring the oil 12 into contact with the probe to cause a switching action. The switching action is either optical, electrical e.g. capacitative or conductive, or electromechanical e.g. a float switch. The monitor is used to sense oil levels in engines and gear boxes. It avoids false readings due to the oil getting dirty and e.g. leaving a film on a probe. <IMAGE>
