Title: Capacitive touch control switch panels and method of manufacturing them
IPC: H03K17/96
Filed: 1980-09-22
Abstract: In a touch control switch panel comprising a dielectric sheet 1 carrying a touch switch which comprises a first touchable electrode 2 on one side of the sheet and second and third mutually separated electrodes 7, 8 on the opposite side of the sheet 1 and in capacitive relation to the first electrode, there are conflicting requirements as to high switch capacitance, small switch area and scratch and impact resistant dielectric sheet. This difficulty is remedied by forming the dielectric sheet 1 of glass which has been chemically tempered and by constituting at least one electrode 2, 7 or 8 by a coating deposited on the sheet 1. The electrode 2 is preferably a tin oxide or indium oxide coating while the electrodes 7 and 8 are preferably of conductive enamel. The dielectric sheet 1 may be provided with an opaque coating layer 5 and/or bonded to a backing support e.g. of synthetic plastics material. <IMAGE>
Patent GB-2084931-A (GB)
Title: Heat transfer printing
IPC: D06P5/24
Filed: 1980-10-10
Abstract: A laminated transfer sheet comprises a paper backing sheet 1 printed with a sublimible transfer ink 2, a polyester film 4 over the printed surface of the backing sheet and heat-sensitive adhesive 6 over the polyester film. The bond between the paper backing sheet 1 and the polyester film 4 is provided by an adhesive 3 which under heat transfer printing conditions is pervious to the sublimible transfer ink and releases its bond between the backing sheet and the film. Thus when heat and pressure are applied to the unprinted exposed side of the paper backing sheet, the heat sublimible transfer ink sublimes to form an image on the polyester film; the film is released from its backing sheet; and the heat-sensitive adhesive 6 is activated to adhere the film to a substrate over which it is placed. This substrate may be made receptive to the sublimible ink by the film. <IMAGE>

Title: Disc record playback
IPC: G11B3/00
Filed: 1978-12-12
Abstract: In order that a cartridge 78 may vertically track a reference path 9 on a disc, a reference path signal z for e.g. servoing the arm is derived by sensing the arm vertical position x by arm sensor 80 and subtracting a signal y provided by a second stylus 78b riding on the path 9, e.g. that lands between the disc grooves, and representing the distance from cartridge to reference path. If z controls a vertical arm servo, the signal provided by the main stylus 78a represents the groove modulation correctly relative to the reference path. <IMAGE>

Patent GB-2094578-A (GB)
Title: Method and apparatus for reducing capacitor-switching transient signals
IPC: H03L7/10
Filed: 1979-02-27
Abstract: In a logging-while-drilling apparatus a phase-locked loop locks onto the carrier of a received PSK signal, and provides timing signals for the demodulation. The phase-locked loop includes a voltage controlled oscillator, and a phase comparator a variable bandwidth filter, which couples the comparator output to the control terminal of the VCO. A controller is coupled to the variable filter to change the bandwidth of the filter (300) as a function of the received input signal. Before phaselock is achieved a wide bandwidth is chosen for the filter, and after lock a narrower bandwidth is chosen for loop stability. Bandwidth is changed by switching in one of capacitors C11-C13 and resistors R11-R13. The filter gain factor is consequently changed. To prevent loss of phaselock during switching, the capacitors not being switched in are kept pre-charged to appropriate voltages by circuitry 421-426. <IMAGE>

Title: Magnesium halide production and use
IPC: C08F10/00
Filed: 1982-03-16
Abstract: A solid magnesium or manganese halide material containing ions of a transition metal incorporated therein is prepared by adding to a fused magnesium or manganese halide a transition metal or a transition metal compound, and obtaining a solid magnesium or manganese halide material which contains ions of the transition metal. When using a transition metal compound, the valency of the transition metal in the solid magnesium or manganese halide material is different from its valency in the original transition metal compound. Using a transition metal, the fused salt may include a material which is capable of oxidising the transition metal to give ions of the transition metal, such materials being, for example, cadmium halide or zinc halide. The material which is capable of oxidising the transition metal may form volatile reaction by-products, or give solid by-products which are readily separated from the magnesium halide material. The solid magnesium or manganese halide material may be obtained in a suitable form by melt- spraying or grinding. Olefin polymerisation catalysts may include the product of this process.

IPC: B23B31/12
Filed: 1982-07-27
Abstract: In a chuck for use in percussion drilling tapered jaws 6 centre a normal drill 4 sufficiently lightly for a striker 5 to drive the drill axially relatively to the chuck body 1, between which and sleeve 9 a spring 14 acts to cause clamping surfaces 8 to hold the jaws 6 closed on the drill against the force of springs 2l. The surfaces 8 are on an annulus 15 fixed to sleeve 9 and the body 1 rotates these parts through pin and slot connection 12, 13. The drill 4 is positively rotated by being clamped securely between prismatic surfaces 10.3 and clamping member 10.4 on a dog 10 in a transverse slot 17 in annulus 15 which rotates the dog without preventing it from moving along the chuck axis under the blows of the striker.
