Patent GB-2078466-A (GB)
Title: Micro-processor controlled coin-box telephone instruments
IPC: G07F9/06
Filed: 1981-06-11
Abstract: The invention relates to microprocessor controlled coin operated telephone instruments which use only the telephone line to derive power. The instrument is arranged to include means for switching off most of the active components of the instrument when the instrument is idle and power-on restart means adapted to cause power to active components of the instrument to be switched on when the instrument is taken into use. Typically the instrument remains in the powered down state until one of a number of input events occurs as a result of (a) an automatically generated call to report a fault or cash-box full condition, (b) an incoming call is detected, (c) a normal outgoing call is commenced or (d) an insulation line test condition is detected.

Title: Permanent magnet electromagnetic machines
IPC: H02K1/14
Filed: 1978-10-03
Abstract: An electromagnetic machine (particularly an electric motor) is based on the design described in British Patent Application No. 48794/74 (Serial Number 1 541 211). Eddy current losses are reduced by forming the backing plates 1, 2 from ferrite composite material (16, 18) which may be sintered and mounting an array of discrete magnets (20, 20a, 22, 22a) thereon (Fig. 2).

Title: Apparatus for cleaning air of paint entrained therein
Inventor: FULTON ROBERT
IPC: B05B14/46
Filed: 1982-02-11
Abstract: Apparatus 1 for cleaning air of paint entrained therein, in a spray chamber 3 comprises a conduit 6 in the partition 2 open at both ends, one of which opens into the chamber 3 and the other of which opens into, and is spaced from a boundary wall 4 of, the cleaning chamber 5, the end 8 having a smaller cross-sectional area than that of the one end 7, and means to pass liquid cleaning medium over the partition 2, through the conduit 6 and into the cleaning chamber 5, whereby the paint is separated from the air and becomes mixed with the cleaning liquid. The conduit 6 may be of circular, square, rectangular or polygonal cross-section, and the smaller cross-section at end 8 may be achieved by an inwardly bent flange as shown, or by a gradual tapering of the conduit from top to bottom.

Title: Annular hole cutter
Inventor: HOUGEN EVERETT DOUGLAS
IPC: B23B51/04
Filed: 1982-03-01
Abstract: In a modification to the cutter disclosed in UK Patent application No. 20 80 162A, the back-off surface (56) and therefore the inner and intermediate cutting edges (34, 36) are inclined radially inwardly and axially rearwardly at an angle (ab) between +10 DEG  (Figure 10) and -3 DEG  (Figure 14). In the case of a rapid feed rate producing thick chips which do not bend easily, these angles cause the chips to be directed closer to the vertical to facilitate their entry into the flutes (22). An additional back-off surface (86) on the outer cutting edge (38) is inclined upwardly and rearwardly at a high inclination angle (c) of 40 DEG  to 45 DEG  to assist in directing the chip cut by the outer edge (38) away from the wall of the hole being cut and reduce the risk of chipping of the cutting edge. <IMAGE>

Title: Electrically conductive reinforced plastics structures
Inventor: TAYLOR-DUXBURY THOMAS MICHAEL
IPC: H01B1/24
Filed: 1982-08-06
Abstract: An electrically conductive fibre reinforced plastics structure e.g. a pipe section, is formed by impregnating a reinforcement fabric 15, comprising a non-conductive base fabric loaded with electrically conductive particulate carbon, with an uncured synthetic resin and moulding the structure prior to curing of the resin. The reinforcement fabric is commercially available employing a base fabric of non-woven polyester and other materials may be used. The density of carbon loading and consolidation of reinforcement in the structure vary its conductivity. A structure so made exhibits bulk resistivity in the range 10<3>-10<9> Ohm-cms which includes the range 10<5>-10<7> Ohm-cms preferred for the dissipation of electrostatic charge. The uncured synthetic resin is applied by a nozzle 12 to the fabric 15 on an expandable mandrel 11. Other moulding techniques may be used. <IMAGE>
