Patent GB-2111211-A (GB)
Title: Aircraft instruments
Inventor: BRAZENER DAVID JOHN
IPC: G01P1/10
Filed: 1982-11-17
Abstract: A Mach airspeed indicator instrument has a pointer 5 that is rotatable around a fixed airspeed scale and a Mach scale 7, the Mach scale itself being rotated in response to altitude change. A maximum desired speed marker 10 can be rotated around the scales 3 and 7 via a cam 45 that is manually rotated by an external knob 47. Rotation of the Mach scale 7 is coupled via two vertical links 56 and 58 and a lateral arm 57 to rotate a gear ring 52 which carries a peg 51. When the gear ring 52 reaches a certain position the peg 51 contacts and displaces a similar peg 50 which rotates the marker 10 with the Mach scale 7. The Mach value at which this occurs is adjusted manually from outside the instrument by a knob 68. Twisting the knob 68 causes a vertical displacement of a mounting bracket 60 on which the lateral arm 57 is pivotted. The lateral arm 57 is fixed at the end coupled with the Mach scale 7 so that it rotates about that end causing rotation of the gear ring 52 without affecting the Mach scale 7. <IMAGE>

Title: Housing for an electrical installation device
Inventor: SCHMITT HERMANN
IPC: H01H71/02
Filed: 1983-03-31
Abstract: A housing 10 for an electrical installation device, particularly for a circuit breaker, comprises indentations 14, 16 in the wall of the housing 10 which form markings along which a wall section 24 can be removed in order to form an opening. In order that the wall section can also be removed after the device has been assembled the corresponding indentations 14, 16 are provided in the opposite surfaces of the housing wall. In order to prevent the removed wall section 24 from falling into the device, the inner diameter of the marking on the outer surface of the housing is greater than the outer diameter of the marking on the inner surface of the housing. The removable wall section is so formed that it can be rotated and removed by means of a tool, e.g. a screw driver inserted in a slot 22, or a spanner applied to a hexagonal contour 34 (Fig. 4). <IMAGE>

Title: Improvements in or relating to travelling wave tubes
Inventor: COOPER BRIAN FREDERICK
IPC: H01J23/04
Filed: 1983-10-07
Abstract: The invention provides a travelling wave tube having a directly heated cathode. Cathode material is applied in a depression in one U-shaped member of a high resistance alloy material and the return path for heater current is provided by another U-shaped strip member beneath the first. The configurations of the two strip members are similar so that stray magnetic fields generated by the equal but opposite currents flowing therein, tend to neutralize one another. In another embodiment the two strip members are replaced by generally cylindrical members, one member being within the other. The surface of the member providing the return path for heater current is polished where it faces the member carrying the cathode material so as to reflect back heat radiated by the last-mentioned member.

IPC: F16B21/16
Filed: 1984-01-27
Abstract: A rapid coupling device is described particularly for suspending a mine sowing device from an aircraft such as, for example, a helicopter, which allows both mechanical and electrical connections to be made rapidly. This device includes two parts, one (1) for connection to the aircraft and the other (2) to the load, with male and female couplings freely rotatable relative to each other; the coupling is effected by means of movable balls (9) located in a ball carrying cage (10) slidably mounted in one of the parts (1) and engageable with a projection (23) on the other part (2). Upward movement of cage (10) effected by solenoid (18) allows the balls to move outwards and free the projection (23). The electrical connections are effected by contacts (29) sliding on annular tracks (27) to allow rotation of the load relative to the aircraft. <IMAGE>

Patent GB-2184880-A (GB)
Title: Display devices
Inventor: TURNER JOHN HENRY
IPC: H04N3/12
Filed: 1986-08-22
Abstract: A solid state TV screen device comprises a MOS matrix array B and illuminating matrix C in conjunction with this. The MOS capacitor array B may be utilised in two ways. a) by relaxation of the charge bias into the substrate of the matrix which then alters the illuminating matrix electrodes in proportion to their density. b) by sensing of the charge in situ via sensing electrodes and metal connectors to the illuminating matrix electrodes. Both methods requires that the illuminating matrix activation frequency be below the processor frequency. The video signal is fed into the base processor A until full. This line is then clocked up by one line (two for interlacing) and the base register filled again. Both lines are clocked up, and the process is repeated until the frame is full. Readout then occurs by halting clocking keeping bias constantly applied, so that illumination can occur. The process is repeated at a rate of 25 full frames per sec, giving the detailed display required by a TV screen. Only deep buried electrodes are possible for use in this device obviating surface state interference with charge movement. <IMAGE>
