Patent GB-2006899-A (GB)
Title: Power Transmission Mechanisms
IPC: B62D11/12
Filed: 1978-10-18
Abstract: A variable-ratio power transmission mechanism 10 having two output shafts 16, 17 for driving respective wheels or tracks at opposite sides of a heavy off-the-road vehicle, and having a steering mechanism for varying the relative rotational speeds of said shafts, is known. Where the steering mechanism includes a null shaft 30 which is not driven when straight-line travel is required, said shaft has been driveable by hydrostatic means, but these have sometimes proved unreliable. It is therefore proposed to drive the null shaft 30 by mechanical two-speed gearing driven from the input of the power transmission mechanism 10. The null shaft 30 is selectively driveable by said gearing in either direction of rotation through the appropriate one of two progressively engaging clutches 47, 58 until it attains a first speed, and an epicyclic reduction gear 42 in said gearing is then locked up to drive the null shaft 30 in the same direction at a higher speed. <IMAGE>

Patent GB-2039453-A (GB)
Title: Fire safety device
IPC: A62C3/06
Filed: 1979-01-15
Abstract: A fire safety device for automatically and rapidly, closing the lid (2) of a container for inflammable substances in the event of its contents catching fire. The device comprises a support (5) whose lower end-portion (4) is attached to the container and whose upper end-portion (6) provides a means for locating movable rods (7) onto the lower end-portions of which are heat shrunk tubes of thermoplastics materials (10). These act to retain the lid (2) against the action of gravity. On the contents of the container catching fire the tubes of thermoplastics material (10) deform under the action of the heat of the fire allowing the lid (2) to close, extinguishing the flames. The tubes (10) then regain their original form under the action of gravity and by moving the rods (7) the lid (2) can then be reset to the open position. <IMAGE>

Title: High density capacitive touch switch array arrangement
IPC: H01H36/00
Filed: 1979-05-14
Abstract: A capacitive touch switch arrangement is provided which alleviates panel layout problems which result from the minimum area required for proper operation of capacitive touch switches. There is at least a pair of capacitive touch switches, each having, as its input element, a touch pad (84 to 89) of sufficient area for proper operation of the touch switch. A pair of primary touch sensitive areas (58, 60, 62, 64, 66) are delineated, such as by panel indicia 69 to 77, and arranged such that a touch on either primary touch sensitive area activates only one of the respective touch switches. In addition, at least one secondary touch sensitive area (59, 61, 63, 65) is delineated and arranged such that a touch on the secondary touch sensitive area activates both of the adjacent touch switches. A circuit means responsive to the touch switches includes decoding logic for generating different outputs in response to the touching of each of the touch sensitive areas. Thus, there is not a one-for-one correspondence between all of the touch sensitive areas and the touch pads. In particular, there are more delineated touch sensitive areas than touch pads, and the touch sensitive areas may be smaller in area than the touch pads. <IMAGE>

Title: Oscillating transmission mechanisms
IPC: B62M1/24
Filed: 1979-05-17
Abstract: An oscillating transmission drive for a bicycle includes a pair of pedal cranks 5, 6 to each of which is connected a contrate gear sector 8, 9 having an angular extent of about 135 DEG . The sprocket wheel 4 is positioned between the gear sectors and has a smaller diameter than each sector, the wheel 4 being secured to a shaft 3. The cranks 5, 6 are mounted on the shaft 3 by means of unidirectional clutches 7. A rotary lay gear 15 is attached to the bicycle frame, with its rotary axis horizontal and engages each contrate gear sector at a position outside the sprocket wheel. A downward movement of one pedal crank causes the other pedal crank to move upwards, and the bicycle is hence propelled by an oscillating pedal movement. <IMAGE>

Title: Electrocardiographic and Blood Pressure Waveform Simulator Device
IPC: H01R13/66
Filed: 1979-08-31
Abstract: Apparatus for checking the operability of a remote display device and including a waveform generator (44 and 46, 56 and 58) for providing simulated waveforms, incorporates means for coupling the waveforms to the remote display device which includes a bridge network (68) having a variable resistance element in one of the legs. This element is coupled to the waveform generator. An excitation signal from the remote display device is coupled to an input of the bridge. The signals from the generator cause the resistance of the variable resistance element to correspondingly vary and provide simulated waveforms at the output of the bridge network to the remote display device. The device simulates both electrocardiographic and blood pressure waveforms, the beginning of the blood pressure waveform being delayed (70, 72, 74) from the beginning of the electrocardiographic waveform to provide a time sequence of waveforms such as would ordinarily be supplied by a live patient. A cable 154 equipped with plugs 156, 158 may be used to interconnect the simulator and a blood pressure monitor, these being rendered compatible by means of resistors R59-R62. <IMAGE>

Title: Establishing maximum heat transfer within a fluidised bed
IPC: G01K13/02
Filed: 1980-02-06
Abstract: A method for establishing a state of maximum heat transfer within a fluidised bed 2, uses a self-heated temperature sensor 1 which is placed in the bed, the and an unheated temperature sensor 3 also placed in the bed at a distance from the first sensor. During fluidisation the temperatures of the sensors are measured and compared at varying gas flow rates through the bed. The point at which the difference between the two temperatures becomes a minimum corresponds to maximum heat transfer within the bed. The gas flow rate can thus be controlled to maintain this minimum differential, either manually or, by using the output of a comparator 6 to control a motorised gas flow valve 11. <IMAGE>
