Abstract: 1385091 Mechanical switches; retractive switches SWF-SPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU GmbH 14 July 1972 [14 July 1971] 32956/72 Heading H1N In a steering column switch assembly, when the operating lever 41 is moved parallel to the steering wheel plane it operates direction indicator switch 52 and when lever 41 is moved normal to that plane it operates an additional switching device. The additional switching device comprises a first sliding contact carrier 10 carrying a bridging contact 12, carrier 10 being moved by lever 41 against the action of return spring 16 from a normal position to two operating positions in both of which the headlamps are on (to flash them, since carrier 10 returns to its original position when lever 41 is released) and a second contact carrier 20 carrying bridging contact 23. Carrier 20 has two positions which it holds when moved into them, headlamps dipped and headlamps on, carrier 20 being moved by carrier 10 (through shoulders 11, 25). Moving lever 41 and consequently carrier 10 into its second operating position moves carrier 20 into one held position and again moving lever 41 into its second operating position moves carrier 20 into its other held position, and so on in sequence. Carrier 20 is held in its two positions by a ball 22 in a bore 21 in carrier 20 riding round a heart-shaped cam track 40 in housing 16, carrier 20 being urged to its original position, dipped lamps, by return spring 27. Pushbutton 51 may also operate direction indicator switch 52.

Title: Improvements relating to the manufacture of luminescent screens
IPC: H01J9/22
Filed: 1945-12-06
Abstract: 601,937. Luminescent screens. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 6, 1945, No. 33084. Convention date, Dec. 19, 1941. Drawings to Specification. [Class 39 (i)] A finely divided luminescent material is deposited on a support, e.g. the end wall of a cathode-ray tube, by covering the support with a cushioning liquid, distributing the material over the liquid and allowing it to settle on to the support. Additional layers may be added in the same way and then the liquid is slowly decanted. The cushioning liquid and the suspension liquid may both be water, ether or carbon disulphide, the phosphor suspension being sprayed through a convex spherical nozzle which is constantly rotated. The support and the cushioning liquid are held at rest whilst the phosphor settles, and the liquid is then removed from the support or tube by tilting the container and siphoning away the liquid. Simultaneously a warm dry gas is circulated over the support to dry the uncovered screen, and the tilting, siphoning and drying are carried out at such a rate as to avoid avalanching on sliding of both the wet exposed screen and the part of the screen still covered which are both kept below the critical angle for such a displacement. Specification 535,947 is referred to.

Title: Production of oxygen
IPC: A62B21/00
Filed: 1962-08-29
Abstract: An exothermic composition comprises the following ingredients: .Sodium chlorate.86-93% .Manganese dioxide.4-6% .Mangesium.1.2-8.0% The composition is in the form of an aggregate of blocks having an ignition device, those adjacent to the ignition device having a greater Mg content (3.0-8.0%).  The ignition device may comprise an aluminium sheath enclosing a mixture of potassium permanganate and iron filings.ALSO:Oxygen is produced by igniting blocks containing an alkali metal chlorate, a metal oxide catalyst which lowers the decomposition temperature of the chlorate, e.g. manganese dioxide, and magnesium in amount from 1.2 to 8% by weight, the magnesium content of the blocks in direct contact with the ignition device being at least 3% by weight; and removing entrained dust and other released gases from the oxygen produced. The proportion of Mg may be the same in all blocks not ignited, or it may decrease.  The ignited magnesium causes the chlorate to decompose, thus releasing oxygen. Thin metal casing 1 has glass fibre packing 5 inserted in the base, on which rest the blocks 6, containing 4% magnesium, and 7, 8, 9, each with 2% magnesium.  The blocks are surrounded with granulated quicklime 24. Igniters comprising e.g. an aluminium sheath enclosing a mixture of potassium permanganate and iron filings, and an electric fuse, are contained in block 6, and covered by asbestos fibre 12. Above block 6 there is a chemical purifying layer 17 of soda lime, which is covered with a metal grid 18; and above this there is a glass fibre filtering layer 19, which is covered by grid 20.

Abstract: 664,140. Magnetic sound recording and reproducing apparatus. RADIO CORPORATION OF AMERICA. Dec. 29, 1949. [Dec. 30, 1948] No. 33238/49. Class 40 (ii). To provide a linear frequence response characteristic the transducer 11 has a coil 15 supplied with radio frequency from an oscillator 17. During reproduction this frequency is modulated in accordance with the signals on the magnetic record 1, and these changes in frequency are then converted to audio signals by a balanced disinminator circuit 19. which may be of the type described in Specification 489,094, [Group XL]. Alternatively the audio signals may be taken off across a resistor 21 connected between the grid 23 and cathode 25 of the oscillator. The transducer may be of the split ring type or, as shown, a rectangular yoke comprising soft iron members 11a, 11b, connected by a ferrite arm 13 carrying the coil 15. The radio frequency oscillations from this coil are prevented from erasing the signals on the sound track by making the parts 11a, 11b of soft iron and the arm 13 of open work construction, to form a complete magnetic circuit for the radio frequency flux. A magnetic bias is applied to the arm by a permanent magnet 31. To prevent the flux of this magnet from affecting the signals on the record, a balancing coil 35 is supplied with direct current, For recording ; audio signals from a microphone 41 and amplifier 43 are fed to the coil 35 when a switch 45 is closed,

Abstract: 1,200,501. Semi-conductor devices. LICENTIA PATENT - VERWALTUNGS G.m.b.H. 24 July, 1967, No. 33947/67. Heading H1K. The centre two zones of a PNPN controllable rectifier contain recombination centres to reduce the carrier lifetimes, the concentrations of such centres diminishing in each zone with increasing distance from the central junction. Au may be used to produce these centres in Si, the concentration decreasing by at least an order of magnitude in each zone from 10<SP>14</SP>- 10<SP>15</SP> cm.<SP>-3</SP> at the junction. In one embodiment P-type zones are produced by Ga diffusion into opposite faces of an N-type Si wafer, one of these zones then being removed mechanically and/or chemically. Au is vapour deposited on to the re-exposed N surface, and after diffusion in the excess metal is etched away. P- and N-type epitaxial zones are then applied successively, during which process the Au diffuses further into the original N zone, and also into the epitaxial P zone thereon. Three electrodes are then applied one to each outer zone and one to the inner P zone after etching away part of the epitaxial N-type outer zone. In an alternative embodiment Au is diffused into a PNP structure to provide a homogeneous distribution. The required inhomogeneity is then obtained by out-diffusion or gettering into a vitreous layer of P 2 O 5  or B 2 O 3 . Reference has been directed by the Comptroller to Specification 1,079,492.
