Title: Improvements in and relating to diesel-electric and like power transmission systems
IPC: H02P9/00
Filed: 1932-04-07
Abstract: 396,167. Systems for transmitting mechanical power. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Compagnie Franþaise pour 1'Exploitation des ProcÚdÚs Thomson-Houston; 173, Boulevard Haussmann, Paris.) April 7, 1932, No. 10021. [Class 38 (iv).] Diesel-electric and like systems in which an automatic regulator operated by the engine group controls the field of the main generator 2, so that a substantially constant load is maintained on the engine group, for example of the kind described in Specifications 291,383, [Class 38 (iv), Electric supply and transmission systems, &c.], and 380,497, the automatic regulator 6 is driven through a change speed gear box 9 and controls a rheostat 7 in series with a hand-operated rheostat 5 so that the excitation is strengthened when the engine tends to race. When all resistance has been cut out by the regulator the admission to the cylinders is controlled by a cam operating on rods 8. Preferably the gear box is controlled electromagnetically by a selector 11 and to prevent interrupting the regulator drive the arm of the selector makes one contact before it leaves another, and to ensure that the engine is unloaded at the moment a change in gear is made an interrupter 12 is opened each time the arm 11 is operated. Another interrupter 16 may be included in the circuit, operated tachymetrically, to prevent closure until the engine has reached its new speed. A temporary increase in output may be secured by short-circuiting a resistance 17 in the exciting circuit while operating in the admission ; alternatively a resistance may be paralleled with the rheostat 7 during overload. The drive between gear box and regulator 6 may include a coupling disengaged centrifugally to prevent its excessive speed. The centrifugal regulator shown may be replaced by a tachometer generator controlling the.rheostat 7.

Title: Improvements in and relating to electric discharge tubes
IPC: H01J21/18
Filed: 1926-04-20
Abstract: 274,937. Raytheon Manufacturing Co., and Smith, C. G. April 20, 1926. Vacuum tubes.- In electric discharge devices with input and output circuits correlated to produce oscillations in the output circuit in response to current variations in the input circuit, the output circuit includes electrodes not heated from an external source and separated by a gaseous gap too short normally to permit substantial conduction and the input circuit has means responsive to current variations in the output circuit to render the gap recurrently conducting by gas-ionization unsupporteddischarges. Concentric tubular electrodes 10, 12, Fig. 3, may be supported by insulators 16, 18 at a distance apart of the order of the mean free electron path in a glass or metal receptacle freed from active gases and filled with inert gas. Electrons travelling straight from one electrode to the other do not collide with sufficient gas atoms to produce conduction, but the electrons are deflected to increase the lengths of their paths and render the tube recurrently conducting by the magnetic field of a coil 26, Figs. 2 and 3, in the input circuit 32. The circuit 32 is inductively related at 30 to the output circuit 29 including the electrodes 10, 12. A constant magnetic field is supplied by a constant-current electromagnet or by a permanent magnet 40 with an armature 41 adjustable by members 44, 45. The magnetic fields are so positioned that the discharge occurs at parts of the electrodes remote from the insulators 16, 18 to prevent spattering of metal on the insulators. Specifications 170,015. 180,405 and 218,677 are referred to.

Patent GB-860406-A (GB)
Title: Improvements in processes for the separation of substances by fractional sublimation
IPC: B01D7/00
Filed: 1957-04-01
Abstract: <PICT:0860406/III/1> A plurality of solid components of different volatility is separated from a solid mixture thereof by a process in which at least one of the components of the mixture is sublimed, and the resulting vapours are passed through an extended heating zone, the temperature of which decreases progressively from that of the vapours fed to the zone in such manner that the vapours are progressively condensed to the solid state in the cooler regions of the zone, and wherein the temperature gradient in the zone is thereafter varied in such manner that at least one condensed component is resublimed and at least one condensed component remains in the condensed state.  The process may be effected in a continuous or discontinuous manner and at normal atmospheric or higher or reduced pressure.  An inert gas may be present.  The process may be used to purify iodine, sulphur, salicylic acid, camphor, benzoic acid, naphthalene, arsenic, arsenic oxide, mercury chloride, magnesium, calcium, cadmium, zinc, silver, and manganese, and also compounds of niobium, tantalum, zirconium, hafnium, thorium and uranium. In one embodiment a fractional sublimation of zirconium tetrabromide containing 2% by weight of hafnium bromide is effected in a hard glass apparatus (Fig. 3) comprising 3 main parts namely a lower chamber 31 of elongated shape, a tubular column 32, and a cooling pipe 33.  A tube 35 is provided for the introduction of nitrogen.  Air heated in a furnace 36 passes a thermocouple 37 and enters the column 32 which is filled with silica wool wads.  The zirconium tetrabromide is placed on a porous plate made of sintered glass and heated to 360 DEG  C. by means of an electrical resistance 34.  Fractional condensation is regulated by means of the furnace 36, e.g. to give a temperature of 436 DEG  C. at the bottom of the column and 233 DEG  C. at the top.  In a modification (Fig. 2, not shown) the apparatus comprises two vertical tube sections and two transverse sections making a closed circuit.  In a further modification (Fig. 1, not shown) the sublimate is condensed on to a tube which can be made to slide up and down thus enabling several operations to be performed in the one apparatus, this apparatus may be used to reduce the hafnium tetrachloride content of a sample of zirconium tetrachloride from 1% by weight to 0.02% in 7 operations.

Filed: 1956-04-07
Abstract: 805,450. Making tubes. GUSTIN-BACON MANUFACTURING CO. Inc. April 7, 1956 No. 10679/56. Class 99(2). A web of insulating material impregnated with an uncured resin is helically wound on a continuously and axially advanced mandrel 10, the resin then being cured to form a finished continuous length of tubular insulation ; lengths of the insulation are cut from the mandrel. In the apparatus shown, the tubular mandrel 10 is advanced by driven, friction rollers 19 and is formed by a number of perforated sections 12 connected together by dovetail joints 16. The mandrel passes through a toothed ring 22 in mesh with a gear 46 driven by a motor 42, the ring carrying one or more rotatably mounted rolls 34 of fibrous material 40. Rotation of the ring 22 about the advancing mandrel causes the material to be wound helically on to the mandrel; the edges 50 of the material overlap, but preferably abut on another. The wound material 48 is enclosed by a pair of perforated, semi-cylindrical members 52, 54 which pass, together with the mandrel, through a perforated tube 60 located in a chamber 58 connected to a blower 68, hot air from the latter passing through the perforations in the tube 60 and members 52, 54 to the wound material 48 to cure the resin, and then into the mandrel 10 to be exhausted therefrom. A pair of relatively reciprocatable blades 70, 72 for cutting the wound tube into lengths, and at the joints in the mandrel, are mounted on a carriage 76 reciprocated in the axial direction of the mandrel. The tubes are slit longitudinally but a cutter 84, and a shoe 88 facilitates stripping of the tubes from the mandrel sections, the latter being then attached to a section about which material is being wound.
