Title: Circuit for driving electro- optical display unit
IPC: G01R13/40
Filed: 1979-02-02
Abstract: A circuit for driving a liquid crystal bar graph display unit has a major object to provide a circuit of simple construction, which may be used even when the numbers of block electrodes and segment electrodes are altered. In order to perform this object, the analog value of an input signal is converted to a pulse train of the number proportional to the analog value of the input signal. This pulse train is further divided in frequency by n (where n represents the number of segments per one block) so as to form the pulse train of l/n as compared with the original pulse train. The voltage to be applied to the segment electrodes is further selected in response to the original pulse train and the number of pulses divided in frequency into l/n, and the voltage to be applied to the block electrodes is selected in response to the number of pulses thus divided as above. <IMAGE>
Patent GB-2042830-A (GB)
Title: Ballast circuit for discharge lamp
IPC: H05B41/231
Filed: 1979-11-05
Abstract: A tuned output high frequency inverter (9) drives a lamp load (11). A voltage corresponding to the load current is derived in feedback rectifier 15, and fed to storage capacitor 91. This voltage then smoothes the pulsed d.c. input voltage derived from rectifier 7, by means of isolating diode 93 and also stabilises the output voltage of the inverter. The starting circuit (19) including diac 101, provides a negative pulse to transistor 43, turning transistor 41 on via the transformer 63 upon which, storage capacitor 91 is charged from the feedback rectifier 15 and the diac can no longer breakdown. Hence the starting circuit is effectively isolated whilst the oscillator is running. <IMAGE>

Patent GB-2059513-A (GB)
Title: Device for Melting and Dispensing Thermoplastic Adhesive
IPC: B05C17/005
Filed: 1980-07-10
Abstract: In a hand held heated dispensing device contact of an operator's hand with sensors 8 carried by hand-grip 2 serves to switch the device from a low temperature setting to a high temperature setting for a melting chamber (not visible) to which solid adhesive 5 is fed by operation of trigger 4 to dispense molten adhesive from nozzle 6. When the device is put down (e.g. for positioning a component to be adhered in place) removal of the operator's hand from contact with the sensors 8 causes switching back, if desired after a short time delay, to the low temperature setting. This arrangement reduces the time necessary for the device to be brought up to temperature each time it is required to be used. <IMAGE>

Filed: 1980-09-23
Abstract: In peritoneal dialysis equipment a spike 14 for detachably connecting one part of the equipment to another has a removable cover 8, 9, 10 which is axially compressible. The inner surface of the cover 8, 9, 10 contacts the spike 14 and can retain sterilising medium. A tubular non-compressible separable axial extension of the cover may be provided as a handle. When the spike 14 is inserted into e.g. a bag of dialysis liquid the handle is removed and the cover 8, 9, 10 is compressed. Fitting, removing, compression, and expansion of the cover 8, 9, 10 all cause the inner surface to wipe the spike 14 and act to sterilise it. This reduces the risk of infection associated with the use of such equipment. <IMAGE>

Title: Improvements in foot restraining straps
Inventor: TILLBROOK ANTHONY ARTHUR CHARL
IPC: B63B35/81
Filed: 1982-08-25
Abstract: A conventional foot restraining strap for a windsurfing or like board is made of a polyethylene webbing material 1 anchored at its ends to the board 5 and bent into a bow. The bowed portion is normally covered with a protective foam sleeve 12. The webbing material currently used tends to take on a set when deformed out of shape and does not recover very quickly to its intended bowed form. Also, it tends to present rough edges which may be dangerous to a bare foot surfer and also tends to tear. It has been found that by using a copolymer of ethylene and vinyl acetate, e.g. with 18% of vinyl acetate, in the form of a homogeneous strip, these disadvantages may be avoided. The ends of the strip 1 may be anchored to the board 5 by screwing into captive nuts 7. <IMAGE>
