Title: Liquid Crystal Driving Circuit
IPC: G02F1/133
Filed: 1981-05-13
Abstract: A liquid crystal matrix driving circuit has a display data generator (28), a column driver (26) driving the column electrodes of a liquid crystal display unit (20) according to data from the data generator (28), and a row driver (30) driving the row electrodes cyclically. A further control circuit (32) generates a control signal of duty-cycle which may be manually variable. Row and column drivers (30,26) output zero voltage to the respective electrodes in response to the control signal from the control circuit (32). The duty cycle may be varied to compensate for temperature changes. <IMAGE>

Patent GB-2085625-A (GB)
Title: Multiprocessor system
IPC: B66B1/18
Filed: 1981-10-15
Abstract: The multiprocessor system enables rapid comparison of results determined from input data at the individual microprocessors. During a first phase of the comparison the results which are to be compared are transferred from the individual microprocessors to counters in connection logic components each of which is associated with an individual microprocessor. During a second comparison phase which is started by activating a comparison line to which all the connection logic components are connected via a bus driver, the counters are simultaneously started to count for periods of time each of which corresponds to the result which has been transferred to the respective counter. The comparison line is deactivated by the counter with which the longest counting period is associated. For the purpose of determining the deactivated state, the comparison line is connected to respective inputs of the connection logic components. An interrupt request is produced at that one of the microprocessors which is associated with the counter having the longest counting period. The multiprocessor system can be used, for example, to control the optimum operation of an elevator system.

Title: Preparation of glass container for thermoplastic closure
IPC: B29C65/00
Filed: 1982-01-25
Abstract: A method for preparing a glass container, and for sealing a glass mouth of a container and the seal are described. The sealing surface, or finish, of the container is subjected to a hot end chemical treatment after forming and before annealing to enhance adhesion between the container finish and a thermoplastic membrane seal. The container is next annealed and after annealing is subjected to a cold end treatment in which the exterior container surface is coated with a material which enhances the lubricity and increases the abrasion and scratch resistance of the container. The container finish only is then subjected to brief heat treatment sufficient to remove any lubricity enhancing material from the finish. A membrane comprising a thermoplastic film is pressed onto the container finish and heated causing glass-plastic adhesion and forming a closure.

Patent GB-2102355-A (GB)
Title: Improvements in high pressure hydraulic systems
Inventor: HARRISON ANTHONY WILLIAM
IPC: B60G17/056
Filed: 1982-06-11
Abstract: In a high pressure hydraulic system fluid is supplied from a source (1) to a slave unit (2) through a control valve assembly (3), which is operative to maintain the slave unit in a desired condition. Leakage from the slave unit (2) past the control valve (3) with the source (1) inoperative is undesirable but it is difficult at high pressures to provide a control valve with leakproof seals which requires small valve- operating forces. Thus the control valve (3) has first and second ports (6, 12) communicating with the source (1) and the slave unit (2), and a single valve member (14) which in association with a single elastomeric seal (16) controls fluid flow. The valve member (14) in a closed position closes the first port (6) and in an open position allows fluid flow between the ports (6.12). Movement of the valve member (14) is controlled by the pressure differential across it, and valve-operating means, for example, a spring (19) and a plate (17) operated by magnetic means. The source (1) preferably is a pump, with a cycling pressure output. The slave unit (2) may be a suspension strut, as part of a vehicle suspension levelling system, with the magnetic valve operating means and the pump controlled by an electronic control system. <IMAGE>
Patent GB-2123648-A (GB)
Title: Implantable tissue-stimulating prosthesis
Inventor: DALY CHRISTOPHER N
IPC: H04R25/00
Filed: 1982-06-28
Abstract: An implantable tissue-stimulating prosthesis, such as a cochlear prosthesis, is described which can be implemented in single-chip form and which permits flexibility in stimulation strategy and data transmission format. Only sixteen electrodes are required for stimulating fifteen different sites. Each site is stimulated by a biphasic pulse under control of two adjacent electrodes whose polarities are reversed in the middle of the site stimulation cycle. Although the transmission scheme requires a pulse- width modulation format, the precise form of the format can be varied in order to accommodate widely different stimulation strategies. For example, only a single site may be stimulated during each transmission frame or multiple sites may be stimulated during the same frame. Although only one site can be stimulated at any instant of time, the system cycling is so fast that "simultaneous" site stimulations are perceived. The system is designed for minimum power usage, and its operation is fail-safe in that no site may be stimulated for longer than a pre-set time interval.

Patent GB-2121236-A (GB)
Title: Liquid level indicators
Inventor: ANDREWS JOHN HENRY
IPC: G01F23/16
Filed: 1982-11-19
Abstract: A liquid level indicator, e.g. for checking the oil level in an i.c. engine, comprises a collapsible air container 4 enclosing a spring 5 both fixed within a rigid housing assembled from circular sections 6 and 7. The interior of the air container restrictively communicates with an air vent 16 but otherwise communicates airtightly with a dip-tube 1 having an opening adapted to be immersed in liquid. A second spring 14 biases a translucent push button 20 carrying an electric lamp 21 which can be pressed to collapse the air container, this lamp being illuminated from an external source at terminals 12 and 15 connecting to the springs 5, 14 whose moveable parts lead to the lamp 21 directly by the second spring 14 and indirectly by the other spring 5 via a contact stud 8 activated by the air container, so that when pressure on the push button is released electrical continuity is temporarily broken at this lamp if the air container is unable to re-inflate immediately in consequence of the dip-tube opening being immersed in liquid. The lamp 21 may be replaced by a metal contact and the indicator connected to a warning lamp. <IMAGE>

Patent GB-2142008-A (GB)
Title: Treatment of water
Inventor: GARRETT M E
IPC: C02F3/30
Filed: 1984-04-05
Abstract: Water having a biochemical oxygen demand (eg sewage) is treated in a relatively shallow tank 102 which may for example take the form of a sewage lagoon. A wall 112 separates one treatment zone 114 from another treatment zone 116. Both the zones 114 and 116 communicate with a common inlet zone 118 into which water for treatment is fed from pipe 120. Both the zones 114 and 116 have outlet weirs 124 and 126 respectively. In operation, the water in one of the zones 114 and 116 is oxygenated in the presence of suspended bacterial solids that are effective to reduce the biochemical oxygen demand, while at the same time solids in the other of the zones 114 and 116 are allowed to settle, clear liquid flowing out of the tank over the outlet weir associated with that zone. At the end of a chosen period, the zone in which solids were settling is oxygenated, and the solids in the other zone are allowed to settle. In this way it is possible to treat the water continuously without the need to employ a separate settlement tank. <IMAGE>
