Title: Liquid ceystal display cell and method of making the same
IPC: G02F1/1343
Filed: 1977-07-01
Abstract: In order in a liquid-crystal display cell having a twisted structure of the nematic liquid crystal to prevent in conjunction with as small as possible an angle of inclination of the molecules the occurrence of regions with an opposite sense of twist, a molecular orientation film (11) consisting of two layers is applied to a substrate (2) by means of an electrode layer (1), the two layers being successively deposited by oblique vapour deposition with different inclinations to the substrate (2). The liquid-crystal display cell thus produced has a wide angle of view and the orientating film produces a small angle of inclination of the molecules to the substrate, and this is optimum for multiplex operation. The orientation film can be designed to withstand heat treatment of approximately 500 DEG C, and is thus optimally suitable for liquid-crystal display cells sealed by glass solder. <IMAGE>

Abstract: 678,893. Valve actuating mechanism. McMASTER, D. May 10, 1951 [Nov. 13, 1950], No. 27673/50. Class 135. In a poultry battery installation having a feeding carriage moving slowly and continuously around the cages, the carriage supports a tank adapted to operate a valve supplying the tank with water on each circuit of the carriage in accordance with the amount of water in the tank. As shown, a tank 1, Fig. 1, mounted on a feeding carriage 2 is provided at its leading end with a guidepost 3 having guide-plates 4, 7 respectively and slidable on the post. The plate 7 is fixed to a rod 5 slidably passing through the plate 4 and carrying at its lower end a float 6, Fig. 3, so that the height of the plate 7 above the tank depends on the water level in the tank. On each circuit of the carriage the plate 7 engages a rod 10 to open a rotary plug cock 8, the amount of opening depending on the height of the plate 7. Thus, e.g. when the tank is nearly full the plate 7 is high on the post 3 and the cock opens a small amount only. An extension 10b of the rod 10 engages a plate 11 fixed to the trailing end of the tank to close the valve.

To enable a tubular carton having its ends closed by flaps to be made from a strip of material with a minimum of waste material, end flaps 7, 8 are cut from one side and folded outwardly and downwardly over the open ends of the tubular body. If the body has a top side of double thickness the under thickness 2 forms a closed top. Alternatively a plastics sheet, which may be in the form of a bag (14, Fig. 5) may be provided on the inside of the body. The end flaps 7, 8 have flanges 9, 10 and may also have flanges on each end. These flanges may be tucked inside the body or secured together so that each flap 7, 8 forms a pivoted flanged cap. The flanges may have dove-tail shaped extensions thereon engaging slits in the body. The sheet 2 can form a hinged lid. One end of the body can be extended and folded to form partitions 15, which alternatively may be vertical. The side walls may be of double thickness for increased strength.

Title: Improvements relating to phase displacing systems for oscillatory directional radio transmitters, receivers or the like
IPC: G01S1/02
Filed: 1937-10-13
Abstract: 503,428. Directive wireless signalling. AGA-BALTIC RADIO AKTIEBOLAG. Oct.. 13, 1937, No. 27838. Convention date, Nov. 26, 1936. [Class 40 (v)] Relates to directional systems of the kind in which the effect of a directional aerial 2, 3, Fig. 1, is combined with that of a non-directional aerial 7, the phase of the latter being periodically reversed so that the resulting cardioid field is swung over from the thin-line position 20, Fig. 3b, to the thick-line position 20<1>, to give a concentrated field along the median line X Y. The invention consists in driving the phase-reversing coupling-condenser at a variable instead of a constant speed, so as to produce complementary signals which are free from " clicks " or interfering sounds along the median line: The rotating vanes 12, 13, Fig. 1, connect the aerial first to one end, and then to the other of the inductance coil 6, thus varying the phase of the voltage supplied to or derived from that aerial. The condenser 8...13 is shown in vertical section in Fig. 2b, in series with a coupling condenser 16, 17. The moving plates of the keying condenser are driven by a motor 15, either with an oscillatory motion, or continuously in one direction at variable speed, so that there is a longer "dwell" at one extreme position than in the other. The " dot " and "dash" signals may also be produced by displacing the centre of the fixed condenser plates relatively to the moving plates.

A sealed envelope containing a semi-conductor device also contains a gettering element comprising a porous matrix impregnated with activated oxides of alkaline earth metals. As shown, a transistor 18 is mounted on the top of a cup-like member 15 having a glass insert 16 for supporting leads 17 leading to the transistor. A cap 11 sealed to the cup-like member 15 by welded flanges 13, 14 defines an air-tight volume containing the transistor. The cap member contains the impregnated matrix 21 which may be of sintered nickel, copper, kovar, or of ceramic material such as alumina, impregnated with barium and/or strontium oxide. The disc-shaped matrix may be impregnated with a mixture of barium and strontium carbonate and one surface of the disc is then lightly plated with evaporated gold. The disc is then brazed to the inside of the cap, the heat used also serving to convert the carbonate to oxide. Alternatively, the porous matrix may be formed in situ in the cap, by depositing the material within the cap and then sintering, after which a measured amount of activated oxide is added to the matrix. Detailed methods of preparing the matrix and impregnating materials are described.

Title: Manufacture of quinophthalone-monosulphonic acids
IPC: C09B25/00
Filed: 1934-10-03
Abstract: Quinophthalone monosulphonic acids are obtained by heating the quinophthalone sulphate salts or sulphur trioxide addition products preferably to 130--200 DEG  C.  The sulphate salts are obtained by combining molecular proportions of the quinophthalone and sulphuric acid monohydrate, and the sulphur trioxide addition product by passing a current of air and sulphur trioxide over the quinophthalone, both reactions, if desired, in presence of a solvent. According to examples: (1) quinophthalone is converted to sulphate salt and heated under reduced pressure at 190 DEG  C.; (2) 3-hydroxyquinophthalone is converted to sulphate salt and heated under reduced pressure at 190 DEG  C.; (3) 3-hydroxyquinophthalone is converted to the sulphur trioxide addition product and heated under reduced pressure at 190 DEG  C.; (4) 3-hydroxyquinophthalone is converted to sulphate salt in tetrachlorethane, followed by distillation and precipitation.  The products are monosulphonic acids which dye wool yellow shades from an acid bath.
