Abstract: 1,104,967. Fault-detecting: computer instruction decoding. WESTERN ELECTRIC CO. Inc. 4 Aug., 1965 [5 Aug., 1964], No. 33300/65. Headings G4H, G4A. A matrix of crosspoint devices operable by coincident currents is checked to verify that only one is operated at a time. Binary to 1-out-of-n pretranslators select one row and one column of a matrix of transistor gates to produce one output at the intersection, the system being usable for decoding computer instruction codes. In Figs. 2, 3 (2, not shown), the outputs of the crosspoint elements on one main diagonal of the matrix are connected to one gate 278 in an error detecting circuit and those of the rest to another 280. The matrix can be tested by selecting the diagonal elements in turn and then an equal number of other elements, one from each row and column, also in turn. An alarm is given if the error detecting gates give similar outputs. Each of the error detecting gates can be tested by energizing a further input to one gate while, via the matrix, energizing all the previously-mentioned inputs of the other gate in turn. In Fig. 4 (not shown), a single error detecting gate is used, connected to all matrix outputs, and two inhibiting lines are used during testing to apply inhibiting signals to two groups of crosspoint elements as their members are being selected. The matrix may be 3-dimensional (Fig. 6, not shown) with three error-detecting gates, allowing the row containing a faulty crosspoint to be indicated. In Figs. 7, 8 (not shown), the crosspoint outputs of a 4 x 4 matrix are so connected to four error detecting gates that only one crosspoint in a given row or column is connected to a given gate. An error indication is given if more than one error detecting gate produces an output. The error detecting gates can themselves be tested by selecting them in pairs via extra input terminals thereto.

Abstract: 1409045 Coalescing KNITMESH LTD G A DAVIES and G V JEFFREYS 8 Sept 1972 [16 July 1971] 33444/71 Headings B1D and BIT Liquid droplets of more than 100 microns dia. in a gas stream or in a stream of another liquid (e.g. kerosene-water mixture) are coalesced by passage through or over an element which comprises a mixture of two materials with different surface energy levels. In the case of a liquid-liquid mixture each material is preferentially wetted by a respective liquid, and this is stated to allow higher flow rates with effective coalescing than does a single material and also permits equally effective coalescing whichever liquid is the dispersed phase. An element may be made of one material and have areas of the other material applied thereto by spraying, painting or printing or applied as a uniform layer parts of which are then removed by scratching or etching. Another element comprises one or more layers of woven or knitted fabric whose threads may be of different materials, or each thread may comprise a plurality of strands of different materials. Alternatively an element may comprise a porous mass of tubes, rings, plates or saddles, of different materials or each comprising two materials. Exemplified mixtures of materials are stainless steel with nylon, P.T.F.E., polyethylene or polypropylene in a ratio by length of from 3:1 to 1:3. Metals, metal oxides, ceramics and glass are suitable to mix with synthetic polymers. Coalescing by contacting the fluid with the mixture of materials precedes a settling separation stage.

[Class 39 (i)] An electrode consists of a gauze body formed of nickel wires and of wires of metal, such as tungsten or molybdenum, which has a melting point higher than that of nickel, and the entire surface of the body including that of the internal passages is coated with an electronemitting material. A high - pressure lamp comprises a vessel 10, Fig. 1, of fused silica or of the material known under the Registered Trade Mark of pyrex or nonex and is provided with hemispherical ends which rest in metal rings 8, 9 welded to tungsten wires 6, 7 carried by the pinch of a surrounding glass envelope 1. A mica ring 11, fixed to the ring 9, supports the vessel 10 from the container 1. Tungsten leading - in wires 12 are connected through stranded nickel wires 18 and the conductors 2, 6 to leading-in wires passing through the outer envelope. The filling consists of argon at 5 mm. and of mercury, sodium, thallium or cadmium which is completely evaporated during operation. The weight of a mercury filling is 150 mg. and the temperature of the coolest part of the vessel 10 is 360 C. The outer envelope may be evacuated or filled with gas, e.g. nitrogen at half an atmosphere, at a pressure which does not permit of a discharge between the leading-in wires. Starting is facilitated by one or more turns of wire 15 connected to one of the electrodes. The external surface of the bottom of the vessel 10 is coated with a gold lacquer. Each hollow cylindrical electrode 14 consists of gauze rolled in such manner that the nickel wires are transverse to the longitudinal axis of the electrode. Members on the gauze facilitate the attachment of the electrode to a support and prevent unwinding. Each electrode is secured to a leading-in wire through a loop of tungsten or molybdenum wire to minimize the conduction of heat to the seals. The cut sides of the gauze provide points for the discharge. The electrode is fired in hydrogen and then dipped in a suspension of 15 grms. of barium carbonate and 15 grms. of strontium carbonate in 100 c.c. of water. The lamp is connected in series with a choke 17, which is not saturated by the maximum discharge current, and may be combined with incandescent lamps. In a modification, the vessel 21, Fig. 3, consists of fused silica or fluorite, and the electrode leads 12 pass through graded seals, each of which supports through an asbestos tube a heater winding 24 of one ohm resistance, formed, e.g. of nickel-chromium wire. The heaters maintain the temperature of the seal and are connected between the electrodes and screening terminals 25. An apertured baffle 26 minimizes convection currents to maintain the temperature of the lower electrode. The weight of the mercury filling is 35 mg. Dimensions and voltages are given in the Specification.
