Filed: 1967-03-09
Abstract: 1,163,567. Ladle teeming carriage. WELLMAN MACHINES Ltd. 24 May, 1968 [9 March, 1967], No. 11127/67. Heading F4B. A ladle teeming carriage comprises a wheeled rectangular chassis 1, 2, 3, which supports on its top surface by means of load cells 8 an open rectangular top-frame 7. Frame 7 in turn supports a ladle support frame 18 within which a bottom pour ladle 9 may be mounted from the top for teeming into an ingot mould 21. The suspension of ladle support frame 18 from top frame 7 is such as to allow both a vertical and a horizontal limited adjustment of the position of the ladle 9 relative to that of the ingot mould 21. Two parallel rotatable shafts 10, 11 mounted across opposed ends of the top frame 7 are interconnected at their ends by parallel lever linkages 12, 13 to ensure their synchronous rotation, on actuation of hydraulic rams 14 connected to the shaft 10 by short levers 15. The consequent rotation of the shafts causes movement of further levers 16 to which suspension links 17, carrying the ladle support frame 18, are pivotably secured to effect vertical adjustment of frame 18 and ladle 9. The horizontal adjustment is effected by actuation of rams 22 which push against frame 18 causing it and the ladle 9 to move sideways as the suspension links 17 swivel about their top pivots.

Filed: 1959-04-02
Abstract: 885,040. Two-part couplings. GENERAL ELECTRIC CO. Ltd., BLOCH, A., and PARKER, E. L. March 21, 1960 [April 2, 1959], No. 11244/59. Class 38 (1). A socket connector has a contact and a further member which are relatively movable by insertion of a co-operating plug, e.g. a printed circuit board, to produce pressure between the mating plug and socket contacts. As shown, Figs. 1 and 2, pairs of contacts 3, 4, e.g. of beryllium copper, secured in the base 11  of an insulating housing 1, extend into an aperture 2 in a movable insulating member 8 having inclined surfaces 15, 16 against which the contacts bear. A plug inserted between contacts 3, 4 with light rubbing engagement depresses the member 8 within the housing, thereby causing inclined surfaces 15, 16 to force the ends of the contacts against the inserted plug. Where the contacts have gold surfaces, rubbing is avoided in an embodiment, Fig. 3, in which the contacts 5, 6 are secured in a movable member 36 and inclined surfaces 42 are provided on the housing so that the socket contacts move with the inserted plug contacts when the member 36 is depressed. In both embodiments the resilience of the contacts returns the movable member to the position shown when the plug is removed.

Title: Improvements in the manufacture of monocrystals
IPC: C30B29/26
Filed: 1963-03-22
Abstract: 969,448. Ceramic monocrystals. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. March 22, 1963 [March 29, 1962], No. 11476/63. Heading B1G. A ceramic monocrystal is produced by passing a hot non-molten zone or front through a polycrystalline agglomerate containing 0À1-1  mol per cent of a substance which enters into solid solution during the heating. The temperature of heating (which embraces the temperature of solid solution) is between the temperatures of agglomeration and fusion. The substance is such as to retard crystal growth below solid solution temperature and accelerate crystal growth above solid solution temperature. It may be added before or after formation of the material of the polycrystalline agglomerate. The material may be a ferrite, perovskite, garnet, or ruby. The ferrite may be manganese-zinc or nickel-zinc ferrite. The additive may be silica, lanthanum oxide, neodymium oxide, palladium oxide, scandium oxide, aluminium oxide, chromium oxide, gadolinium oxide, thorium oxide, hafnium oxide, zirconium oxide, titanium oxide, tantalum oxide, or niobium oxide ; or ferric oxide calcined at 1000 ‹C. It may have a particle size of less than 1000 Angstrom Units. Growth of the monocrystal may be initiated by passing a hot zone through a restriction 8 near one end of the rod, Fig. 3, forming an initial hot point, Figs. 4 and 5, or the use of a preformed seed orientated in a desired manner, Figs. 7 and 8. Heating may be by a single resistance or induction heating coil 4 or a pair of outwardly moving coils 5 and 6 and cooling may be aided by a cooling ring 7 which precedes the heating coil. A hot front may be passed through the material by means of heat passed from a furnace 19 through a slit 17, Fig. 6. A bicrystal may be produced by passing two hot zones towards one another. The material may be in the form of a solid or hollow rod or ring or square frame.

Title: Stabilized High VOltage Source.
IPC: H02M7/162
Filed: 1968-03-08
Abstract: 1,179,221. A.C. to D.C. converters. THOMSON-CSF. 8 March, 1968 [10 March, 1967], No. 11559/68. Heading H2F. [Also in Division G3] A stabilized high-voltage A.C./D.C. converter comprises a high-voltage rectifier bridge 16 (Fig. 2), e.g. to supply a magnetron M, energized via a step-up transformer 1, the primary current of which is controlled by a thyristor Th in a diode bridge network 4, thus controlling the transformer secondary voltage and the rectifier output voltage. The thyristor is in turn controlled in dependence upon the magnitude of the D.C. output voltage from bridge 16, by a magnetic amplifier circuit, as follows. In the inoperative position of a switch I<SP>1</SP> as shown, the amplifier cores 11, 12 are saturated and a capacitor C is shortcircuited. When the switch is closed the rectifier 16 supplies current to the load and to a resistor R1 causing a transistor 14, connected as an integrator, to conduct whereby current from a D.C. source S2 flows through a control winding 13. The cores saturation is thus reduced and the impedance of windings 8, 9 thereon increases, reducing the gate voltage supplied by diodes D1, D2 to the thyristor and the angle during which the thyristor is conductive. Thereby the current through transformer 1 is regulated. Fluctuation of load current causes fluctuation in current in winding 13 which affects the gate bias to control the thyristor in a manner to counteract the variation. To prevent damage to the load if the source voltage S1 is too high when first switched on there is provided a second control winding 17, which causes the gate voltage to increase gradually. Before switching I<SP>1</SP>, current from S2 flows through 17 and a resistor R3 and is relatively high so that the cores are unsaturated and the gate voltage would be too low to allow the thyristor to strike. When the switch I<SP>1</SP> is operated removing the short-circuit on capacitor C, the current in 17 charges up the capacitor and thus drops to zero exponentially. The cores become progressively saturated and the gate voltage and conducting angle of Th also increase exponentially. Thus the regulating system has sufficient time to step-in and prevent excessive voltage output to the load.

Abstract: 377,212. Automatic circuit-breakers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Thumim, C.; P.O. Box 5312, Philadelphia, U.S.A.) April 20, 1931, No. 11696. Convention date, April 18, 1930. [Class 38 (v).] The operating rod 1 and opening spring 7 of a circuit-breaker are connected to separate levers 11, 12 so that during the closing movement, the rod 1 descends further than the top of the spring and in the closed position the end of the rod abuts the end of the compressed spring. To close the circuit-breaker, a pair of motors 2, 3 drive centrifugal devices and so turn the lever 4 clockwise, this motion is imparted through links 13, 14, 15, the intermediate pivots of which are constrained to move in defined paths by links 19, 21, to the lever 12, and by means of a roller 16, on the common pivot of link 15 and lever 12, to the lever 4. In the closed position the right-hand end of a catch 28 drops on the left side of a pin 29 on the lever 4 and so retains the circuit-breaker closed. In any position of the apparatus, tripping is effected by turning a catch 25 clockwise so as to clear a roller 24 on the end of a lever 23, which thereupon turns counterclockwise and moves a lever 20 similarly. This causes upward movement of the link 21 with consequent buckling of the toggle formed by links 13, 14. Both the spring 7 and rod 1 are released and the spring acts upon the lower end of the rod 1 driving the initial part of its motion and is then arrested by a buffer spring 40. As the toggle 13, 14 buckles, its common pivot pin engages an arm of the catch 28 so as to turn it counterclockwise and free it from the pin 29, whereupon a resetting spring 32 returns the apparatus to the initial position ready for a reclosure.

Abstract: 169,475. Monks, A., and Turner, T. R. April 28, 1920. Cutting-out apparatus.-Apparatus for stamping out cards from sheet material comprises two sets of feed-rollers 3, 4 connected by gearing 8, 9, 10, 6, the shaft 18 of the wheel 8 being driven from a wheel 30 on the punch-operating shaft through spur-wheels 29, 28, and 27. A pin 26 on the wheel 27 communicates intermittent motion to the shaft 18 through a. star-wheel 25, a gear-wheel 24, an idle wheel 22, pinion 21 and a worm-wheel 20 engaging a worm 19 on the shaft 18. Below the roller 3 is mounted a roller 11 carried bv an arm 12 secured to a shaft 13 to which are also fixed a cranked arm 14, bearing an adjustable stop 15, and a spring-retracted arm 40 by means of which the roller may be lowered against the influence of the spring 16. Mounted below the roller 6 is a second roller or a ball 17 supported by a ball 17a. The punching and feeding mechanisms are arranged so that the punch x is only operated when the strip is not being fed. The waste material is drawn off by a roller 32 driven by bevel gearing from a pulley 37 and engaged by an idle roll 31 mounted in a slot 33<a> in a standard 31. The weight of the roll 31 is not sufficient to cause the roller 32 to advance the strip when it is held stationary by the feed rollers 3, 4, but causes a grip when these are feeding the strip.
