Abstract: 835,075. Making wood veneers. WRIGHT & SONS (VENEERS) Ltd., J. (Williamson, J. S.). Aug. 7, 1957, No. 24886/57. Class 145. Wood veneer is produced by cutting veneer sheets from a log or block, eliminating defects from the sheets, applying thermo-setting adhesive to one or both sides, stacking the sheets with the grain of the wood extending in the same direction, compacting the stack under a pressure of 80-140 lbs. per. sq. inch and in a steam tank at a temperature of 80‹F. to 212‹F. and finally slicing veneer sheets from the compacted block. Where the veneer is made from oak, the final slicing is preferably done at an angle of about 30 degrees to the face 20 perpendicular to the laminations 7 and the corners of the block are therefore sawn off at 15 and 16 to facilitate clamping at one corner and slicing at the other. For other woods, such as walnut and maple, the slices may be cut parallel to the face 20. The initial sheets may be stacked in the order and arrangement as cut but other grain effects may be achieved by reversing adjacent sheets end to end or face to face or both. Veneer sheets from different woods may be used in building up the stack, for example, alternate sheets of walnut and maple.

Title: Treatment of molten metal in ladles
Inventor: GEBER HANS
IPC: C21C/
Filed: 1984-07-25
Granted: 1987-09-16
Abstract: When it is required to treat a charge of molten metal in the casting ladle with argon gas the lancing tube (16) is inserted in the opening of the refractory teeming nozzle (15). The opening is then sealed and made gastight by the compression of a rubber sealing ring (19) in the bore. Piped argon gas under pressure is permitted to flow through the lancing tube to emerge through a series of drilled holes (17) located in the tube above the gas sealing ring and below the nozzle stopper. As the sealing prevents any reverse flow the argon gas is forced through between the stopper and nozzle block into the molten charge. The refractory stopper in the closed position, seated against the nozzle block effectively seals the opening against molten metal flow until teeming commences.

Inventor: LUCAS KEITH
IPC: H04N11/24
Filed: 1988-09-02
Abstract: A method of enabling an increase in the vertical definition of a transmitted television signal while preserving its bandwidth including the steps of decimating alternate lines of the television signal and reinterpolating untransmitted alternate lines upon reception. The decimation is accomplished by diagonally filtering the television signal in two dimensions to form a figure of five sample structure. Every other line is then added to the line adjacent to it so that half the lines are available for transmission, each line comprising folded-in high frequency information about missing line samples. Prior to transmission, bnadwidth is converted by filtering the signal to be transmitted at a skew-symmetric low pass filter. Apparatus for encoding and decoding the television signal each includes a two dimensional diagonal filter and line switching and control circuitry. The storage of a full field of a sample data is not required for processing in accordance with the present method. Consequently the present apparatus comprises only line store means associated with the line switching and control circuitry of encoding apparatus.
