Title: Improved process for the purification of arsenic
Inventor: ANTELL GEORGE RICHARD
IPC: C22B30/04
Filed: 1959-04-13
Abstract: 875,898. Obtaining purified arsenic. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 28, 1960 [April 13, 1959], No. 12465/59. Class 82(1) Pure arsenic is obtained by moving a heater 2 progressively along an elongated reaction chamber 1 containing an oxide of arsenic and simultaneously passing a reducing gas, e.g. hydrogen, through in the opposite direction. The reduced arsenic voltalizes and is condensed in the part C of the chamber remote from the heater in the direction of the gas flow. The direction of movement of the heater and of the gas may be periodically reversed to cause further purification of the arsenic. Arsenic contaminated with sulphur may be substituted for the oxide and the arsenic may be formed in situ by thermal decomposition of arsenous hydride. Elements to be alloyed with the pure arsenic, e.g. aluminium, gallium and indium, are placed at D and the heater and gas both moved in this direction; the zone D is then sealed and the constituents alloyed by passing the heater repeatedly in both directions along the sealed tube.

Abstract: 699,706. Fertilizer distributers. LONG, E. D. May 13, 1952 [May 28, 1951], No. 12495/51. Class 6(i) A fertilizer distributer comprises a plunger 5 which reciprocates vertically in a hopper 1 to disturb the material and allow it to flow intermittently between the sides of an opening and the plunger and a stirrer in the form of a shaft 24, driven by the means operating to reciprocate the plunger, and provided with paddles 25. As shown the plunger is reciprocated by cams 12 mounted on a shaft 11 and each operating in a box-like frame 8 which supports the plunger and moves between guides 10 in the walls 7 of the opening. The weight of the fertilizer is taken by hinged adjustable members 19. The material is also stirred by projections 23 which may be provided with extensions 21 and which project into the material. In a modification the plunger reciprocates in the hopper and is driven by a piston from gearing driven together with the paddle shaft from a shaft to which may be fitted land-wheels. In a further modification the plunger may comprise a knife-like member and the rotary agitator may comprise a shaft fitted with arms ex-. tending in various longitudinal directions. The distributer may be used with a seed sower or adapted to be secured to the back of a trailer when the mechanism is driven from the rear wheels of the trailer. The distributer may be attached to the rear of a lorry and a shoot may be provided between the hopper and the lorry to refill the hopper. The distributer may replace the drop back board of a lorry.

Abstract: 841,288. Wrapping-machines. JACKSON, D. R. P., and MOLINS MACHINE CO. Ltd. April 17, 1958 [April 17, 1957], No. 12565/57. Class 94(1). [Also in Group XVI] In a wrapping machine for folding a carton blank about a group of articles such as cigarette packets, carton blanks are fed from a magazine, in which they are supported on edge, by a suction member and roller means and placed in the path of the group for folding initially about the leading end and top and bottom with final folding by rotary and oscillating devices. The blanks 1 are urged towards the suction and roller feeding means 5, 7 and 8 (see Group XVI) by plates 9 which are ocsillated through slots in the magazine base 4 by eccentric bearings 11. The groups are each fed forward by reciprocating pusher 32 and press the blank between plates 36, 37 so that the panel 34 is engaged by the leading end and panels 70, 71 lie on the top and bottom of the group respectively. End tabs 46 are engaged by portions 48 of rotary folders 44 during a period when these are halted temporarily in the vertical position, and these folders then rotate to fold down tabs 47 after reciprocating tucking elements 38, 41 have laid panels 40, 43 respectively on to the trailing end of the group. The partially wrapped group is moved forward by that succeeding while a member 60 retains the tabs 46, 47 in position and end flaps 50 are partially folded down by plates 59 to the position of Fig. 3. A foot 53 dips in to a bath 58 on each side and rises to apply adhesive to the flaps 50 which are finally folded down by vertically reciprocating plates 49.

Abstract: 917,331. Regulating consistency of paper pulp. EKSTROMS MASKINAFFAR A.B., A. April 7, 1961 [April 7, 1960], No. 12690/61. Class 96. [Also in Group XIX] The concentration of fibre in a paper pulp suspension &c. is regulated, using a constantspeed sensing rotor in a chamber 11 on the side of and in direct communication with the flowchannel 10 of the pulp. The rotor may include a propeller 12 or vane and an electric motor with a built-in reduction gear, the motor being supported on a knife-edge suspension 20, so that the turning movement due to the resistance opposed to the rotation of the propeller 12 may be balanced by an arm 22 pressing against an air-filled pressure capsule 24 connected to a control circuit with a valve to control the concentration. The walls of the chamber 11 may have guide plates or bars to assist circulation of the pulp.

Title: Improvements in electric rectifier systems used in power or control systems such as for follow-up systems

Filed: 1940-08-08
Abstract: 604,185. Rectifying. MANDL, A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 8, 1940, No. 12738. [Class 38 (ii)] [Also in Group XXXVIII] In a control system in which uni-directional current through an inductive load varies in correspondence with a variable amplitude A.C. input at 1 connected across on diagonal of a rectifier bridge 3, the other diagonal of which is connected over resistances 5 to a constant A.C. supply 4, current flow though the load is restricted due to blocking of the bridge an alternate half-cycles by supply 4 and to avoid this, particularly when a relatively high frequency such as 1000 v. is used, the load is shunted by a suitably poled rectifier 9. The invention is applicable to selsyn systems in which misalignment voltage (input 1) at the receiver is used to control a motor or Ward-Leonard. system (load 6) which positions a controlled body and restores alignment, e.g. the system described in Specification 527,768, [Group XXXVIII]. The arrangement shown in Fig. 1 provides a non-reversible driving system, but in the case of Fig. 2, the split winding 8a, 8b of a reversible drive are associated with a rectifier bridge 9a which provides for current flow over each windings on alternate half cycles. The input 1 is in phase agreement with or phase opposition to the supply 4 in accordance with the direction of misalignment of the selsyn receiver. Specification 592,208, [Group XXXVIII], also is referred to.

The width of the members 13 may be slightly greater than the distance between the resilient sides 9. The resiliency may be obtained by lining the sides with corrugations or, as shown, having an open section along the length of the rail 6. The guide rail 6 may taper continuously or in a series of steps or have non- tapered sections, Figs. 3-5 (not shown), and may have a rectangular, circular or, as shown, C-shaped cross-section.

The bladed tool cylinder 10 co-operates with a bed roll 16 and feed roll 17. The cylinder 10 is driven by gearing from a shaft 26 and is adjustable relatively to the bed roll by a screw bolt 18 pivoted to the journal box 14. A pad member 30 co-operating with the cylinder is pivoted at its ends in swing arms 32 which are pivoted on the shaft 34 of the roll 16. The pad is formed with a yielding surface 42 backed by soft material 43, Fig. 4. The swing arms 32 are pivoted as at 48 to connecting rods 50 each comprising a stiff spring 56 and being connected to a ring 60 surrounding an eccentric 62 mounted on a shaft 64. The shaft is rapidly oscillated by a lever 74 adjustably locked to a hand lever 68 fast on the shaft and connected by an adjustable pitman to a rapidly rotated crank 82. In the modification shown in Fig. 7, the oscillation of the arms 32 is effected by the engagement of a cam 102 with a cam roll 100 carried by the arms in conjunction with the restoring action of a spring 104 and a rod 106 pivoted to a fixed part of the machine. The rolls 16, 17 may be provided with loose felt sleeves 112, 116, Fig. 4, to take up moisture from a wet hide.
