Title: Automatic reading of public utility meters or the like
Inventor: ARBON DENNIS CHARLES
IPC: G08C19/00
Filed: 1981-09-16
Abstract: A system for automatically reading meters for commodities such as gas, water or electricity on the consumer's premises and, preferably, producing the bill for payment due at the same time. An external sensor is triggered by indexing movement of part of a conventional meter. A processor, connected to the sensor, has a memory in which the signals are accumulated. The processor includes a card reader and printer which on presentation of a card by the consumer causes the information memorised to be released and transferred to the record card. The record card may have control or command information by which the processor is caused to calculate the total payment due for the quantity of commodity consumed so that the bill is printed and presented when the record card is released from the processor following reading and printing. The processor may be connected to more than one meter, and respective channels with associated memories can be provided for each meter. It is proposed that the record card be prepared by the relevant Authority, posted or delivered to the consumer for postal or like return, and cost savings on labour intensive meter readings can be made. <IMAGE>

Patent GB-2090779-A (GB)
Title: Wear resistant insert for cast lightweight pistons and method of casting
IPC: B22D19/00
Filed: 1981-12-08
Abstract: The wear resistant insert is an annular ring (30)' of austenitic iron alloy. It has a peripheral surface (32) which conforms to the exterior of the piston into which it is to be cast. At least one projection, e.g. a plurality of frangible tabs (34) project outward from the periphery. When casting a piston, the insert is supported, by means of the projection(s), on a ledge (18) in a die cavity. A predetermined amount of aluminium alloy is poured into the die cavity and the cavity is closed by a punch which applies a force on the solidifying alloy. As the aluminium alloy shrinks during solidification, the pressure severs the frangible tabs allowing the insert to shift. <IMAGE>
Patent GB-2092349-A (GB)
Title: Apparatus for electronically scanning data carriers by infrared light
IPC: G06K7/12
Filed: 1981-12-23
Abstract: In a card-reader a light source consists of individual photodiodes 21, 22 arranged in lines and columns each of which has a phototransistor 8.5 located opposite to it. When a card is inserted it trips a switch which enables the information stored in the card to be read, whereby the column diodes 21 receives pulses only at the instant of data acceptance. This is achieved by using three timing elements 27, 28, 30 which are triggered by a RS flip-flop circuit 10. One timing element 30 produces a pulse in response to one line diode 23 being masked by the card and the second timing element 27 is started by the leading edge of this pulse. This timing element causes the column diodes 22 to receive a short pulse of current via a switching element 29. Another timing element 28 started by the trailing edge of the pulse supplies a recording impulse with which the information from the card is now registered in manually while the luminous power of column diode is full. By energising photodiodes with pulses this enables them to function with a high light intensity and, with the same working life, guarantee a substantially better identification of information. <IMAGE>

Title: Security marking video tape recordings
Inventor: RAGGETT STEPHEN RICHARD
IPC: G11B20/00
Filed: 1982-03-19
Abstract: A video tape recorder is adapted to record security code markings on a tape when recording. The markings are produced in the control track of the tape and do not affect normal playback. Control pulses from a sync separator (13) which are normally stretched to, say, 28 mS for recording on the control track are fed to a further switchable pulse stretcher (17) controlled by a modulator control (18). The pulse stretcher (17) selectively alters the width of control pulses from 28 mS to, say, 18 mS in accordance with code from the control (18) to pulse width modulate the pulses. Leading edges of the pulses which are employed for timing during playback are not affected.

Title: Method and apparatus for retreading vehicle tyres
Inventor: GRIPENHOLT NINNEH
IPC: B22D41/08
Filed: 1983-05-05
Abstract: Tyres are retreaded by using a pre-vulcanised tread and an uncured layer of rubber between this and the carcass, the rubber being cured by applying high frequency from above the tread. This rubber is also locally heated at or near its edges by extra heating outside the tyre. - Specifically the same h/f generator is used to heat both the outermost area of the rubber adhesive between carcass and tread and also the edges area of the rubber. The h/f energy is therefore more efficiently utilised, and the edge application is adjusted so that it at least equals the heat losses from those areas. The whole cure of the adhesive rubber layer is thus made more effective. As an alternative to using high loss factor rubber for h/f heating the edges, e.g. a ring of high loss factor material can be applied to each edge area and thus heat up the rubber edges externally. - Method eliminates the usual problem of cooling at the edges when the assembly is cured in an autoclave contg. unheated pressurised air.(0/8)
