Patent GB-2076193-A (GB)
Title: Keyboards
IPC: H01H13/807
Filed: 1980-05-15
Abstract: To facilitate the production of "customised" keyboards, a keyboard is based on a printed circuit board which carries two sets of printed tracks (10, 11, 12 and 15, 16, 17) connected by further tracks (24) to sets of pads (20, 21) each defining a possible key location. When a key is operated it connects its pads together to set up a "row column" intersection which is then encoded by a microprocessor on the board. In another form, the two sets of tracks extend along one pair of parallel sides of the key pad area, with tracks at right angles to those of the two sets between the tracks thereof and the pads. <IMAGE>

Title: Process for punching and bending strip or wire stock material
IPC: B21D5/01
Filed: 1980-06-23
Abstract: A process for punching and bending strip or wire stock material particularly suitable for very thin material to be made into components having a relatively large number of bends. The stock is drawn from a supply and transported by traction past a punching press (10); after punching has been effected the stock is transported by a stock feed unit (18) this time by thrust, towards a bending station (26) where it is acted on by a plurality of bending units (14.1) to effect the required shaping. A brake (40), in advance of the punching press (10) with respect to the direction of transport of the stock material, ensures that the stock is maintained under a slight tension for the punching operation, thereby improving accuracy of the cut. <IMAGE>

Title: Oscillating and vibrating machine
IPC: B22C15/10
Filed: 1980-07-21
Abstract: The present invention relates to an arrangement for imparting vibrating movements with different frequencies and/or amplitudes extending over a relatively large variation range to a setting-up bench (3) e.g. for the reception of sand moulding boxes in an oscillating and vibrating machine, the bench (3) being raisable and lowerable relative to a fixed stand with a stationary roller table (2) arranged in it, and the vibrating movements being produced by a number of vibrators (36) attached to the bench (3). The vertical movements of the bench (3) relative to the fixed stand (1) are under the control of spring elements fitted between the bench (3) and the fixed stand and/or the foundations respectively. Between the bench (3) and the foundations the spring elements may be formed by air bellows, and between the setting-up bench (3) and the stand (1) said spring elements may be damping elements arranged to strike against fixed stops in the stand. The vibrators (36) may include rotary speed control providing different frequencies, and by regulation of the supply pressure to the air bellows, the amplitude of the vibrations can be adjusted. <IMAGE>

Patent GB-2080550-A (GB)
Title: Battery monitoring system
IPC: G01R31/00
Filed: 1981-06-29
Abstract: The battery is divided into nine 24V sub-packs. During the first part of each discharge, the state of charge is calculated from the charge withdrawn value, determined from integrating charge and discharge currents and from a value representing the charge storage capacity of the battery 10. During the last part of discharge, the state of charge is evaluated from the voltage of the sub-pack having the lowest voltage after compensating for polarization voltage, and used to up-date the charge storage capacity value. The maximum traction motor current is progressively limited during the last part of discharge in accordance with the state of charge. During charging, in a first phase the charge withdrawn is replaced whilst progressively reducing the charging current in accordance with the charge withdrawn value. At the end of the first phase the sub-pack having the lowest voltage is found and, during a second phase, the battery is charged until the rate of voltage rise of this sub-pack falls below a critical level. The battery is then given an overcharge, and at periodic intervals the battery is given an equalising charge. <IMAGE>
