Filed: 1926-12-07
Abstract: 286,379. Elkington & Co., Ltd., and Hutton, F. W. Dec. 7, 1926. Wick burners, solid flame and flame regulating in; oil reservoirs.-A spirit lamp suitable for heating kettles, dishes, toasters &c. is provided with a detachable domed closure member 5 having on its lower surface a threaded boss 5d which screws into a ring 6<a> in the reservoir 6 and forms a concealed joint. The ring 6<a> is connected to the reservoir body by a flange 6<b> thus forming an anular channel 11 in which asbestos or like packing 12 is inserted. The wick tube 7 is inserted centrally in the boss 5d and may be secured by a bayonet connection to wires 6<c> at the base of the reservoir. The flame is regulated by sliding a sleeve 8 on the wick tube by means of a spindle 10 operating through rack and pinion gearing 9. Alternatively the wick tube may be vertically adjustable. The vapour forming in the reservoir escapes through apertures 5<e> in the boss 5d into the dome 5a and is conveyed to the flame either through a tube 13 or through apertures 5f in the upper part of the dome. Preferably a flange 5g surrounds the apertures 5f. The ring on the stand supporting the reservoir 6 is preferably lined with wood fibre or other non-conducting material.

Title: Apparatus for providing a speed reference signal
Inventor: GARE JOHN ROBERT
IPC: B66B1/16
Filed: 1964-08-05
Abstract: 1,112,377. Control of motors. ENGLISH ELECTRIC CO. Ltd. 4 Aug., 1965 [5 Aug., 1964], No. 31873/64. Heading H2J. [Also in Division G3] When a drive motor moves a cage from a datum position in a mine shaft, counter 12 receives pulses from generator 10, the number counted from zero being proportional to the distance the cage has travelled. The output signal of the counter is converted to an analogue signal so that square-root function generator 19 produces a speed reference signal. At a predetermined distance from the datum, the counter provides a signal for gate 15 which produces an inhibit signal to gate 11 whereby the counter is rendered insensitive to further pulses from the generator 10. Thereafter the speed reference signal has a constant magnitude. When the cage passes a fixed point in the shaft, a retardation signal from memory device 13 prevents gate 15 from producing the inhibit signal and energizes controller 14 to subtract the pulses derived from generator 10 from the number registered in the counter which commences to count down towards zero. The speed reference signal is thus reduced according to a decelerating part of a preset speed-distance cycle. When the cage is within a creep-speed zone, gate 22 energizes amplifier 24 so that the reference signal is now derived from generator 26. Manual control of the speed of the drive motor is effected by controller 30 associated with reference counter 28. Manual operation lies within the limits set by the speed-distance cycle. When the number of pulse counts representing the speed set by controller 30 is equal to the number registered in counter 28, comparator 29 produces a control signal for gate 27 which renders the counter 28 insensitive to further pulses from generator 10. Counter 18 is then supplied with a steady signal. If the controller 30 is adjusted for lower speed, comparator 29 actuates controller 32 whereby counter 28 subtracts pulses and cancels the signal to gate 27. The reference counter then counts down until the number of pulses set by the manual controller equals the number registered in the counter. Comparator 31 prevents the number registered in counter 28 from exceeding the number in counter 12. The square-root function generator provides linear acceleration and deceleration.

Abstract: 1315538 Electro-forming printing screens SCREEN PRINTING SYSTEMS Inc 1 July 1970 [2 July 1969] 31979/70 Heading C7B [Also in Divisions B6 and G2] A printing screen, or a blank from which a printing screen can be made, is produced by electrolytic deposition of a metal 16 which may be nickel on a sheet of wire mesh 10 which may be of stainless steel while the mesh is in contact with an electrically-conductive member 11. The member may be a steel plate with a polished surface, so that the nickel, which completely envelopes the mesh, can be stripped from it with a smooth surface. Preferably the nickel is electrolytically deposited from a nickel sulphamate bath, containing a plurality of nickel bars connected to an anode contact and with the mesh connected to a cathode of a rectifier. A further layer of nickel may be added after the mesh and its nickel coating have been removed from the steel plate. In place of a steel plate, the mesh may be wound about a polished metal mandrel, which during plating is surrounded by cicumferentially spaced anodes. An imaged printing screen may be made directly, without a subsequent etching step, by depositing a resist pattern 35 on a smooth surface of a plate 37, applying a mesh and electrolytically depositing metal on the mesh. Over the plate a deposit which closes the pores of the mesh is formed, but over the resist open pores remain between the plated wires.
