Title: Liquid-crystal cells
IPC: G04G17/04
Filed: 1973-06-21
Abstract: 1381429 Liquid crystal cell ELECTROVAC FABRIKATION ELEKTROTECHNISCHER SPEZIALARTIKEL GmbH 21 June 1973 [3 July 1972] 29566/73 Heading H4F In a cell comprising a layer of liquid crystal material between two plates sealed at their margins, a thin film electrode is disposed on the major surface of at least one plate and has a portion extending over an edge face of the plate where it is covered by a metal coating applied by stoving, vapour deposition or cathodic deposition. Solder per se may be deposited on the coating or a metal pad or blade soldered thereto, to connect the electrode to an external circuit. If electrodes are disposed on both plates, with superimposed extending portions, the metal coating interconnects them. The position of an aperture in the edge of the cell for filling purposes may coincide with the position of the extending portions, so that, after filling, the cell is hermetically sealed with synthetic resin (for interconnection of the two electrodes only) or with an amalgam (alloy), or conductive adhesive (for additional connection to an external circuit). The edge of the plate(s) may be bevelled where the extending portion of the electrode exits, or along the entire edge. As particularly described, one electrode may be reflective, and the plates are of glass and sealed together with glass solder. A stack of cells (alternate plates and liquid crystal material) may be formed, the respective extending electrode portions (and filling apertures) being offset from each other. The metal coating may include a first layer of chromium for adhesion to the electrode, a second easily solderable layer (copper, silver, tin) and a third optional oxidation resistant layer, such as gold.

Title: Improvements in or relating to radio receivers
IPC: H04N5/60
Filed: 1936-11-02
Abstract: 484,404. Valve circuits for wireless reception. PERCIVAL, W. S. Nov. 2, 1936, No. 29756. [Class 40 (v)] In a superheterodyne receiver for television and sound employing a single oscillator and a common amplifier for the two intermediate frequency channels, the low-pass amplifier is provided with a band-pass output for the vision signals which are fed directly to a rectifier which constitutes the whole or a substantial part of the matching termination for the bandpass output. The intermediate frequency amplifier V3 ... V6 couplings are designed in conjunction with the valve capacities as described in Specification 475,490. A cut-off at the lower end of the intermediate frequency spectrum is effected by the condenser 16 and leak resistance 17 and by the use of small condensers 19 to give de-generation of the frequencies below the intermediate frequency spectrum. The output from the valve V6 is applied through the series tuned circuit 29, 30 to a shunt circuit formed by inductance 31 and the input capacity of the rectifier. The load impedance 32 is low and with the rectifier forms the terminating impedance of the coupling network. Sound signals are suppressed by degeneration produced by the circuit 22, 23 and this circuit may be utilized to feed these signals to a separate amplifier. If the cut-off at the lower end of the intermediate frequency spectrum reduces the amplification of a portion of the signal frequencies means may be provided to compensate this loss. Specifications 449,205 and 453,484 also are referred to.

Title: Improvements in or relating to semi-conductor devices having variable electric characteristics
IPC: H03D1/10
Filed: 1954-10-20
Abstract: 770,066. Semi-conductor devices. SIEMENSSCHUCKERTWERKE AKT.-GES. Oct. 20, 1954 [Oct. 20, 1953; April 24, 1954], No. 30283/54. Addition to 750,134. Drawings to Specification. Class 37. [Also in Group XL (b)] A semi-conductor device according to the parent Specification has a surface of the semiconductor subjected to radiation which provides a third means for controlling the currentvoltage characteristic of the device. The device, as described in the prior Specification, comprises an intrinsic semi-conductor body subjected to electric and magnetic fields at right angles to each other, thereby modifying the resistance of the semi-conductor body due to the production of a depleted region (the "magnetic barrier layer") having fewer electrons and holes than exist under thermal equilibrium conditions. The depleted region may be 10 cms. in thickness. In the present invention, radiation is applied to the depleted side of the body to generate electron-hole pairs therein which reduces the extent and intensity of the depleted region, and thus modifies the semi-conductor resistance. The arrangement may be such that the radiation penetrates the whole of the magnetic barrier layer, thus effectively reducing its thickness, or only the surface region, thus weakening the effect of the barrier layer by increasing the number of carriers in this region. The radiation may consist of light, infra-red, X-rays, γ-rays, or particles such as neutrons or α or #-rays. Details of the depth of penetration for varying wavelengths, are given for germanium and indium antimonide. Silicon, germanium, grey tin, FeS, and A III B V  compounds such as InSb, GaSb, AlSb and InAs, are given as examples of semi-conductor material. The importance of carrier mobility is discussed and the invention enables the dark current to be maintained at a low level when using relatively low resistance materials. The arrangement is less sensitive to temperature than PN-junction arrangements. The device may be used as a rectifier, as described in the parent Specification, by causing two opposite surfaces of the semiconductor body to have different carrier recombination characteristics, and the radiation may then be used to control the rectification characteristic. By connecting such a device in series with an A.C. source and a D.C. motor (Fig. 8 not shown), the speed of the motor may be controlled according to the intensity of the radiation. The device may also be used as a photo-electric cell, and also for demodulating a modulated radiation to provide an electrical output (Fig. 11, not shown).
