Title: Improvements in or relating to electro-chemical processes of producing manganese from aqueous manganese salt solution
IPC: C25C1/10
Filed: 1944-09-14
Abstract: 597,220. Electrodeposition of manganese and manganese dioxide. EVER READY CO. (GREAT BRITAIN), Ltd., and ABEL, E. Sept. 14, 1944, No. 17585. [Class 41] Manganese is deposited from an aqueous manganese salt solution on or into a cathode consisting of or coated with mercury or an amalgam with current density about 80-120 amps. per sq. ft. ; a high hydrogen overvoltage is thereby maintained. The mercury coating on a cathode, e.g. of stainless steel, may be provided by simultaneous electrodeposition with the manganese ; alternatively, the cathode may be dipped in mercury from time to time. To maintain the overvoltage the mercury or amalgam surface must be renewed frequently by circulation or agitation or in the case of a coated electrode by wiping. Acid solutions of pH about 1 may be employed. The apparatus shown comprises a tank 1, e.g. of ferrous metal coated with lead or rubber having at its base a trough 8 of rubber or ebonite to which mercury is supplied by a pipe 9 and from which it is constantly drawn off by a pipe, not shown, connected to the negative cable. The anodes consist of lead sheets 5 clamped between bars 4. Stirrers 17 for the mercury and 18 for the electrolyte are mounted on shafts 15. Electrolyte is supplied at 2 and withdrawn at 3 A steam heater coil 14 is provided. Manganese is removed from the mercury withdrawn by filtering or distillation. The electrolyte may be a solution of manganese sulphate containing 300 gms. per litre at room temperature. The spent electrolyte containing sulphuric acid may be used to leach manganese ore. By operating at temperature 85‹ C. with a current density at the anode, e.g. 15 amps. per sq. ft., less than that at the cathode, manganese dioxide may be simultaneously produced, being collected-in thin cloths (not shown) surrounding the anodes. When a solid cathode, e.g. an amalgam with silver or tin, or one coated with mercury, is employed, it should be removed and replaced by a fresh one from time to time to restore the high overvoltage condition. Manganese is removed from the old cathode by scraping and distillation.

Filed: 1954-06-17
Abstract: 762,415. Aerials. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 2, 1955 [June 17, 1954], No. 17766/54. Class 40(7) A helical aerial comprises a helical conductor 1 enclosed in dielectric material 5 whose crosssectional dimensions are chosen so that for energy of a predetermined frequency the phase velocity of propagation therein in the direction of the axis of the helix is approximately the same as the velocity of a plane wave in unbounded material of the same kind. This enables the helix to be rigidly supported without deterioration of the radiation pattern. To reduce side lobes the ground plane element 4 provided for the helix may be made conical and coaxial with the helix. Preferably the total apex angle of the cone is made approximately 90 degrees and the open end aperture equal to or greater than one wavelength at the predetermined frequency. The helical conductor itself is dimensioned, taking into account the surrounding dielectric, for the propagation or reception of circulating polarized waves of the before-mentioned predetermined frequency along its axis. The aerial may be fed from a co-axial cable 2, 3 as shown or through a polythene plug at the apex of the cone. In the latter case the helical conductor may be extended through the plug and as a probe into a waveguide provided with a matching piston (Fig. 2, not shown). Four aerials may be arranged in a common plane with 90 degrees angular separations to give omnidirectional transmission of circularly polarized waves.

Title: Improvements in or relating to torsion springs
IPC: C21D9/00
Filed: 1965-04-28
Abstract: Torsion bars for deformable mechanical connections such as suspension springs are produced from rolled, extruded or drawn steel bars from which the decarburized layer has been re-moved by machining or abrasion by subjecting steel bars after machining to final diameter to a surface heat treatment comprising surface heating to above the transformation temperature of the steel, e.g. 875 DEG C., and then quenching, the duration of the heating being such that the interior of the bars is an annealed structure or the structure obtained during the production of the steel bars.  The surface hardening is preferably carried out by continuously passing the bars through an induction heater followed by an oil or a water sprinkler.  Flame or torch heating may alternatively be used.  The process is especially suitable for bars of unalloyed carbon steel containing 0.35 to 0.50% C. and impurity limits of 0.04% P, 0.035% S and 0.065% S+P.  After machining to final diameter, the anchoring head at the ends of the bars may be roughened out by hot forging and given final form by machining or cold forming. After surface hardening, the bars may be tortionally deformed.

Abstract: 913,120. Overhead conveyers. FISHER & LUDLOW Ltd. May 23, 1961 [May 21, 1960], No. 18015/60. Class 104 (2). In a conveyer system of the kind in which a floor trolley (not shown) is advanced by connection to one end of a drive-transmitting element 21, the other end of which is secured to an overhead endless driving chain (not shown) by the use of a connecting drive plate 12 fixed to the chain, the drive transmitting element is of rigid construction and is mounted for pivotal movement about a horizontal axis, e.g. a pin 19, biasing means, e.g. a spring 29, being provided to act on the element 21 and swing it upwardly towards the chain into a horizontal out-of-use position when it is disconnected from the trolley. A vertical pivot pin 16 is fixed to the drive-plate 12 and a sleeve 17, which carries a boss 18 fitted with the pin 19, is fitted for pivotal movement around the pin 16. A forked end 20 of the element 21 engages the pin 19 and this end is secured to the hollow member 26 of a pair of telescopic members 26, 27 which are normally held telescoped together by a spring 28. When the element 21 is connected to a trolley by the use of a detachable connection 23 the member 27 is pulled out of the member 26 against the action of the spring 28 ; thus the length of the element 21 is variable and allows for the trolley being driven over ramps. A hollow cylindrical cam-plate 13, which is arranged to have its greatest depth at the rear in the direction of travel of the chain, is carried by the drive-plate 12. A roller 30 on the element 21 engages with the edge 15 of the camplate 13 and with the element 21 in the driving position, as shown, the drive to the trolley is transmitted from the chain principally through an abutment 15a on the edge 15 and not through the pin 16. As the connection 23 is released from a trolley the member 27 is telescoped inside the member 26 and the action of the spring 29 causes the roller 30 to roll on the cam edge 15 in either direction about the pin 16 to engage in a forward recess 31, in the surface 15, the element 21 moving about the pins 16, 19 so that it is disposed in a horizontal position projecting forwardly of the drive-plate 12 in the direction of travel of the chain. The element 21 may be held in this position by a suitably-shaped abutment (not shown) fixed to the inner member 27 and working within a longitudinal slot in the outer member 26, the abutment engaging with a detent or recess associated with the plate 12 or plate 13. The plate 13 alternatively may be semi-circular in section, so that the element 21 can pivot in one direction only about the pin 16. A series of elements 21 are provided at intervals along the driving chain. Specifications 818,451, 818,452 and 818,453 are referred to.

A bi-stable state circuit comprises a pair of cross-coupled transistors, each crosscoupling path including a capacitor and a further transistor operating as an emitter follower, in which each capacitor has two current paths, one for the change to one stable state, and one for the change to the other. A pair of cross-coupled transistors TX5, TX6 are provided with diodes D1, D2 which form discharge paths for the capacitors C9, C10 respectively during the state in which the discharge path through the base-emitter circuit of the associated transistor TX5 or TX6 is high impedance. Assuming TX5 is conducting and TX6 cut off, then in this stable state, both Dl and D2 are reverse biased. Applying a positive triggering pulse from IP to base of TX5 switches TX5 off and D1 on to provide a current path for C9. Transistor TX6 is switched on due to TX5 switching off to provide the current path for C10.
