Inventor: FLORIDA CHARLES DAVID
IPC: H03K3/55
Filed: 1950-03-13
Abstract: 677,571. Pulse generating circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 12, 1951 [March 13, 1950], No. 6202/50. Class 40 (vi). A pulse generator comprises a capacitor which is alternately charged through a resistor and discharged through a gas-filled discharge tube, a further gaseous discharge tube being switched in shunt with at least a portion of the resistor, so that the capacitor is rapidly charged for a selected portion of its re-charging period. The Figure shows a pulse generator in which at the commencement of a cycle the cold cathode tubes 4 and 16 are non-conductive and capacitor 10 is charged from the H.T. supply via resistors 12 and 25. When a triggering pulse is applied to the trigger electrode 3 of tube 4 the tube fires and capacitor 10 is discharged rapidly through it until the tube 4 is extinguished. Capacitor 10 then commences to recharge slowly through resistors 12 and 25 and the charging current produces a potential drop across resistor capacitor circuit 12, 21 which increases until tube 16 fires. Capacitor 10 then re-charges rapidly through tube 16 and the cycle is thus completed until a further triggering pulse is applied at 1. The output pulse may be derived at terminal 22.

Title: Improvements in device for upsetting metal
IPC: A61F7/02
Filed: 1946-03-01
Abstract: 608,900. Forging-dies. ENGINEERING & RESEARCH CORPORATION. March 1, 1946, No. 6362. Convention date, Oct. 29, 1945. [Class 83 (iv)] In an upsetting or shrinking tool of the kind comprising an integral metallic head from spaced portions of which extend jaws adapted to flex inwardly towards each other when the head is pressed on to the work, the workengaging face of each jaw is convex, with the curvature increasing from the centre of the tool head outwardly to the side, whereby the faces remain in contact with the work during the inward flexing of the jaws. The jaws 24 and 26 are connected to the body of the head by the comparatively narrow sections such as Y-Y and project inwardly, leaving a gap 6 between them at the centre of the head. When the head is pressed on to the work, the jaws move towards each other, so shrinking. the work. The required shape of the jaw surfaces may be obtained by grinding the working faces of the two jaws at right-angles to the centre line G-G of the head over a small lateral distance, thus producing the surface M-1 on each jaw. The jaws are then closed on to a shim slightly narrower than the opening 6, the working faces again ground at right-angles to the centre line to produce the surface M-2 on each jaw. This procedure is continued with thinner shims to form the surfaces M-3, M-4, M-5, &c. The required shape may also be produced by forming the surfaces M-1 and then forcing the head into engagement with a workpiece until the jaw faces wear to the desired shape. The Specification as open to inspection under Sect. 91 comprises also the various forms of shrinking tools, presses and hammers described in Specification 577,614. This matter does not appear in the Specification as accepted.

Title: Production of combustible gas from hydrocarbons
IPC: C01B3/46
Filed: 1951-03-16
Abstract: 701,594. Generating oil gas. HUMPHREYS & GLASGOW, Ltd., and WILLIAMS, N. H. Feb. 29, 1952 [March 16, 1951], No. 6373/51. Class 55 (2) In a cyclic process for making a combustible gas by the catalytic reaction at elevated temperatures of liquid hydrocarbons such as oils or tars or gaseous hydrocarbons such as refinery gas or natural gas with an oxidizing gas comprising steam and/or carbon dioxide and maybe air, each " make" period wherein the hydrocarbon and steam &c. is passed through the heated catalyst mass is followed by a two-stage heating period when air is supplied to burn off deposited carbon and to burn heating fuel when necessary, the air flow in the first stage being in the reverse direction to the flow of " make " gas and in the same direction in the second stage. The apparatus consists of a steam preheating regenerator 1, a chamber 8, containing a catalyst mass consisting, for example, of a mixture of nickel and iron oxides supported on magnesia or alumina, and an air preheating regenerator 13. During the "make" period, steam from pipes 2 and 4 enters the previously heated regenerator 1 to be superheated therein and passes into chamber 8 where it meets a spray of hydrocarbon oil from pipe 9, the steam and oil reacting in the catalyst mass to produce a permanent gas which passes up through regenerator 13, heating the checkerwork therein and discharges to storage through pipe 16. If gaseous hydrocarbons are to be treated they may be admitted with the steam to regenerator 1. At the end of the "make" period, air is admitted to the top of regenerator 13 through pipes 17a and 18 and is preheated therein before passing up through chamber 8 where it burns off the carbon deposited during the "make" and heats the catalyst mass. The resulting hot combustion gases pass down through and heat the regenerator 1 and discharge through a pipe 20. A further supply of air is then passed from pipes 17a and 23 through the plant in the opposite direction to burn any remaining deposits, the combustion gases discharging through stack valve 24. If an excessive amount of heat is generated during this phase, all or part of the hot gas may be diverted through a waste heat boiler 25. If, on the other hand, the combustion of the carbon deposits does not provide sufficient heat for the subsequent gas " make " reactions, a fuel, such as oil together with air, if necessary, may be injected into the apparatus through pipes 29, 30, 31 and 32 and burnt therein to make up the deficiency.

Abstract: 1,057,805. Refining molten metals. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. Feb. 15, 1965 [Feb.14, 1964; Oct.12, 1964 (2); Oct.23, 1964; Nov.26, 1964], No.6430/65. Heading C7D. In a continuous refining process molten metal, particularly iron, is subjected to a jet of refining gases which may contain solid or liquid reagents in suspension, the jet impinging with sufficient force to produce a metal-slag emulsion which discharges into a separate zone where metal and slag are allowed to separate. In one modification the emulsion may be subjected in an intermediate zone to a further jet of oxygen with or without additives, while in another variant the metal after separation is subjected to a further emulsification and subsequent separation, the final slag optionally being recycled to the initial refining zone. In each variant a non-penetrating stream of oxygen may be discharged into the emulsion to burn the evolved carbon monoxide; alternatively a part of the latter may be burnt in the metal feeder channel, the remainder being burnt in the separation vessel. The metal may be subsequently dephosphorized by blowing from an inclined nozzle with a stream of oxygen containing lime and fluorspar, desulphurized with a stream of inert gas containing lime and fluorspar, or recarburized with coke dust. After final deoxidation &c. the metal may be stirred by blowing in nitrogen through porous blocks in the base of the receiver. Suitable forms of apparatus are described and illustrated.

Abstract: 706,419. Electric synchronous movements. SUBMERGED LOG CO., Ltd., [formerly IMPROVED SUBMERGED LOG CO., Ltd.], SWANNELL, A. C., and MARSHALL, W. M. W. March 19, 1952 [March 19, 1951], No. 6538/51. Class 40 (3). [Also in Groups XXXV and XXXVIII] A polyphase motor is driven synchronously with a ship's log driven single phase generator by amplifying thermionically the single phase output, converting the single phase output to polyphase with or without frequency subdivision, and operating the motor therefrom. As shown, Fig. 1, a bar magnet a mounted on the impeller shaft induces an alternating voltage in a coil b, this voltage being amplified in valves e, f to produce a corresponding current output which passes through series connected coils m, s. This single phase output is converted to three phase and applied to the three stator phases q of a self starting synchronous motor r the permanent magnet rotor of which carries the coil s. For the one to three phase conversion, a transformer h carries the identical primary coils m, m<SP>1</SP>, connected in opposition, on its outer limbs, Fig. 2 (not shown), which also carry respectively the identical series opposing secondary coils O, O1. The primary coil m only, is energized from the anode output of the valve f, the winding m' being connected to the coil m at a common point and shunted by a capacitor n to produce the necessary phase shift in the current flow therein. The three phase ouput is taken from the outer ends of the secondaries O. O1 and the adjustable tapping p on a potentiometer series connected between them. The rotor of the synchronous motor which runs in step with the log impeller may be used in any way to indicate speed or displacement. In another embodiment, Fig. 3, using a two phase self-starting synchronous motor r, the single phase output of the inductor coil b is amplified in stages u, v, and frequency divided by two in a multivibrator w. Two outputs in antiphase are fed from the respective anodes of the multivibrator w to multivibrators x, y, which also divide the frequency by two and deliver, respectively, quadrature outputs which are amplified in a cathode follower buffer stage z and applied over power tetrodes 2, 3 to the respective phase windings of the synchronous motor r having a permanent magnet rotor.
