Filed: 1973-03-06
Abstract: 1368728 Selective signalling MOTOROLA Inc 6 March 1973 [8 March 1972] 10854/73 Heading G4H A predetermined bit pattern is recognized in a digital signal by feeding the signal into storage means (e.g. shift register) having one more stage than the number of bits in the pattern, a reference pattern being compared with the first, last and predetermined intermediate stages of the storage means only, the predetermined intermediate stages being those corresponding to bits of the pattern to be recognized which are adjacent a different-valued bit in the pattern, outputs from the comparisons being counted to recognize the pattern. The intermediate stages used (as disclosed) are those corresponding to bits immediately preceding (in time) unequal bits, in the pattern to be recognized, were that pattern occupying the storage means with the exception of the last (to be reached) stage. Equality at the first stage is counted plus one, inequality zero. Equality at any of the intermediate stages used is counted plus one, and inequality minus one. Equality at the last stage is counted minus one, and inequality zero. The counting is done by an accummulator (reset after each bit shift) during feeding of the signal into and through the storage means, the accumulator feeding an up/down counter prevented from counting below zero or above the number of bits in the pattern. The counter feeds a recognition gate. A parallel-to-serial converter may replace the accumulator. The storage means and counter are preset (in various possible ways described) before commencement.

Title: Process of recovering sulphur from sulphide minerals
IPC: C01B17/04
Filed: 1930-04-05
Abstract: Sulphur is recovered from the gases evolved during the smelting of sulphide ores, such as copper pyrites, with a solid reducing agent, e.g. coke in an enclosed blast furnace by passing the gases, which, by adjustment of the blast, contain no free oxygen, at a temperature of 350-400 DEG  C. over a catalyst consisting of a metallic oxide, such as an iron or aluminium oxide, produced from the hydrate and retaining some of the combined water; alternatively, bauxite may be employed.  The temperature of the gases should exceed 350 DEG  C. and dust is removed prior to the catalytic action by passing them first through a settling chamber and then through an electric precipitator. The contained carbon bisulphide, oxysulphide and sulphuretted hydrogen are acted on by the sulphur dioxide formed to produce elementary sulphur.  The reactions are exothermic and the catalytic chamber should be maintained at 350-400 DEG  C. and the temperature of the outgoing gases should not exceed 400 DEG  C.  The reduction of the excess of the sulphur dioxide is effected by the introduction of carbon monoxide, preferably as producer gas, the gases passing through a second catalytic chamber to a condenser, preferably a water-tube boiler, where they are cooled to 150-120 DEG  C.  Liquid sulphur is withdrawn and the gases pass through an electric precipitating chamber maintained at 125-130 DEG  C. where the remainder of the elementary sulphur is deposited.  Traces of sulphur and sulphur compounds may be removed by heating the gases and burning them with air in the presence of a catalyst, the sulphur dioxide formed being removed by scrubbing with water.

Abstract: 864,173. Laminates. PRESSED STEEL CO. Ltd. June 24, 1959 [April 11, 1958], No. 11510/58. Class 140. Trim material for vehicle bodies comprising a facing layer, e.g. of leather cloth, a padding layer, e.g. of foamed polyvinyl chloride or other synthetic resin, and a backing layer of calico or the like is made by giving the facing layer and the padding layer a zig-zag configuration, and bonding them together, the backing layer being subsequently stretched across this assembly and bonded thereto. As shown, upper and lower high-frequency welding platens 1, 3, have registering welding ribs 3, 4, projecting therefrom, and the platen 1 also has longer intermediate ribs 5. Facing and padding materials 6, 7, are drawn from rolls 8, 9, over the ribs 4 and are held by a clamp at their outer ends while being pressed into zig-zag form as shown by the ribs 5 on lowering platen 1; on further lowering the layers are welded together by the co-operating ribs 3, 4. The platen 1 is then raised, an aluminium electrode plate 12 having a terminal roller 13 is moved over the work from right to left, entraining a loop of calico 14 from a roll 15, and the platen 1 again lowered, the ribs 5 pressing the plate 12 on to the work and causing the material 14 to be welded thereto while in taut condition. Finally the work and the plate 12 are moved to the right and the cycle repeated. The padding expands and fills the cells of the facing layer as at 16. In a modification the ribs 5 may be omitted, the platen 1 being moved laterally to enable the ribs 3 to act both to depress and then to weld the work. The padding layer may be straightened before welding, as by reversing the roll 9. The layers may be secured together by adhesives, the upper ribs 3 being then omitted.
