Filed: 1938-03-23
Abstract: 513,269. Mixing liquids and gases. WALLACE & TIERNAN, Ltd., and WILMSLOW, V. A. March 23, 1938, No. 8969. [Class 86] [Also in Group I] In apparatus for adding chlorine &c. in measured quantities to a stream of liquid, of the kind described in Specification 193,032, [Class 86], in which chlorine is supplied to a bell jar sealed with water and is aspirated, together with water, from the jar by the main stream, means are provided for causing a gas pressure measuring-device to indicate any failure in the gas supply. A liquid seal valve may be provided or a float, which, on the failure of the supply, operates indicating means such as a warning, or effects the replacement of the exhausted gas cylinder by a fresh one through a relay, as shown, the gas pressure is measured on a gauge to which atmospheric pressure is admitted on the failure of the gas supply. Gas is admitted to the bell jar 2, Fig. 2, by a pipe 9 fitted with a valve 11 controlled by a float 12. The jar is sealed by water supplied by a float-controlled valve 4 to a trough 1 fitted with an overflow. Gas and water are aspirated by a tube 6 within a tube 7 having an orifice 8 at the top and open to the water at the bottom ; the height of the tube 6 can be varied to vary the pressure at the top of the tube 7, and thus the supply of gas. A tube 16 passes to the top of the tube 7 and is connected to a tube 20, Fig. 3, entering a chamber 22 in which is a baffle 23. The chamber is connected by a tube 21 to the pressure gauge, and is fitted with a tube 24 which depends into a tube 26 open to the atn osphere by a vent 27 and sealed by water contained in a closed vessel 25 connected by a tube 28 with a tube 17 projecting into the bell jar. On the failure of the gas supply the pressure within the bell jar falls causing the water outside the tube 26 to rise and break the sea within the tube 25, thus admitting atmospheric pressure to the gauge; to prevent the water filling the jar, air is admitted after a limited drop in pressure through a tube 14 the end of which lies in an inverted rubber bulb 13.

Title: Improvements relating to machines for trimming metal blanks
IPC: B23G9/00
Filed: 1919-04-12
Abstract: 147,267. White, A. E., (Waterbury Farrel Foundry & Machine Co.). April 12, 1919. Bolts and screws; nuts. -A machine for trimming blanks for nuts, bolts, screws, &c. comprises a pair of opposed cutting-tools 11, 24 relatively movable towards and away from each other, a tool-moving device to cause the tools to cut a blank placed between them and to stop cutting before the opposing edges meet, and a device to move the blank past one of the tools and a finishing-tool 14 disposed near and in alinement with one of the cutting tools. In one form the machine comprises two dies of which one 11 is fixed and the other is movable by a frame 23 actuated by toggles 33, 34 and links 50. 52 from the shaft 53. When the dies have nearly cut through the blank, the die 24 is moved back and a rod 43 adjustably mounted in a sliding frame 38 is moved forward by toggles 39, 40 and pushes the blank through the die 11 and past a finishing die 14. During this movement the stem of the blank enters a guiding bushing 61 carried by a sliding bushing 60 which is actuated by links 63, 65, 66, and a cam on the shaft 53. The bushing 61 is adjustable by means of a nut 71. A fixed stripper rod 72 adjustably mounted in a support 73 ejects the finished blank when the bushing 61 moves to the left. The blanks are fed into a shoot 80 provided with an adjustable cover 81, and are transferred by a feed or cut-off slide 83 which is actuated from the shaft 53 by cam and lever mechanism. The slide 83 has a detachable plate 831 provided with a recess 890 to receive the shank of the blank. When the slide has carried the blank into the plane of the cutters, a pair of spring feed tongs 93 carried by a slide 92 descends and grips the blank by means of detachable fingers 95. The fingers then rise while the slide 83 is withdrawn and then .descend to bring the blank into alinement with the dies. The fingers are made detachable so that thin fingers may be used for short blanks. To enable the thin fingers to be held longer in the lower position than the wider ones, the slide 92 is provided with an adjustable drive. The cutting edges of the dies 11, 24 are preferably formed by angular cuts across the face of the die. The die 24 is mounted in a slide 28 which is horizontally adjustable in a vertically adjustable slide 29. The die 11 is angularly adjustable by means of screws. The planishing surfaces of the die 14 are slightly nearer the axis of the blank than the cutting edges of the dies 11, 24. These dies may be solid or .may be made up of planer tools arranged in groups with their edges forming a circle or polygon.

Abstract: 1,056,271. Speed measurement. ENGLISH ELECTRIC CO. Ltd. June 10, 1963 [March 12, 1962], No. 9384/62. Headings G1K and G1U. In an arrangement for estimating the speed of a uniformly moving body 13 two similar photoelectric sensing devices 10, 11 are located at positions spaced a predetermined distance apart along the path of the body and each device produces a signal when a bar moves past. The first signal operates a switch 16 which connects a steady voltage 18 to a circuit 15 providing a uniform voltage run down, while the second signal causes a record of this voltage at the time of the second signal's occurrence to be made on the indicator 27. From a knowledge of the steady voltage 18 and the distance between the devices 10 and 11 the indicator can be calibrated to read speed directly. The arrangement for producing the uniform voltage run down consists of two CR circuits in series with an extra resistance bridging the two capacitors. Alternatively a battery may be included in the second resistive leg and the extra resistance omitted Fig. 3 (not shown).

Filed: 1967-06-07
Abstract: 1183937 Purifying combustible gas ESSO RESEARCH & ENG CO 24 May 1968 [7 June 1967 27 Feb 1968] 38447/66 and 9533/68 Headings C5G and G10A The gaseous products resulting from burning, at least partially, a solid, liquid or gaseous hydrocarbon fuel, are freed of sulphur, which is recovered, by contacting the products with a fluidized bed of Mg and/or Ca oxide (or carbonate, e.g. dolomite or limestone, at a temperature, e.g. 800 to 1100C., which decomposes it to form an oxide). The bed material is regenerated, e.g. in the same or another fluidized bed, and the oxide recycled to the original bed, sulphur being recovered conventionally. The process is applicable to the H2, CO-containing gases from a partial combustion process, and the burning (partial combustion) stage may be performed in the fluidized bed, e.g. in a fluidized bed boiler. The sulphur may be absorbed in the bed under oxidizing conditions to form sulphates which are then reduced in the regenerating stage, or absorbed under reducing conditions to form sulphides which are subsequently oxidized. Sulphate regeneration is preferably performed over a catalyst, e.g. bauxite which reduces SO 2  to sulphur, and if performed in the same bed as the burning stage, may be carried out in a standpipe supplied with fuel oil to burn excess air. Sulphide regeneration is by air-stripping at 1000C. to form SO 2  and sulphate. An apparatus is described in which both the boiler and the regenerator comprise two superposed fluidized beds, the boiler having a partial combustion (reduction) stage beneath a subsequent oxidation stage, and the regenerator the converse, bed material circulating between the two lower beds, and oxide being supplied to the upper boiler bed from the lower regenerator, from which SO 2  passes for reduction over an alumina catalyst in the upper regenerator bed. The inventive process is applicable to fluidized beds burning coal, and other impurities, especially vanadium, are removed.
