Title: Improvements in or relating to the production of silicon
Inventor: STERLING HENLEY FRANK
IPC: C30B25/02
Filed: 1959-07-17
Abstract: <PICT:0903021/III/1> Silicon is produced at the heated tip of a mono- or poly-crystalline seed by directing a stream of silane and a surrounding stream of hydrogen on to the molten tip.  The hydrogen is maintained at a temperature below that of decomposition of silane so as to prevent substantially the gas phase decomposition of the silane.  The silane is at a molecular concentration substantially less than "normal".  As shown in Figs. 1 and 2, silane is admitted through four tubes 17 and hydrogen through twelve surrounding tubes 18 in an outer tube 13 and the silane is decomposed at the upper surface of a seed 12 inductively heated by means of a primary coil 7, a secondary coil 8, and a work coil 10. The reaction product gas is withdrawn through a circular slot 15 around the inner periphery of an annular tube 15a connected to a tube 14 and a vacuum pump (not shown), the slot being kept free of silicon dust by means of a rotary wiper 16.  The seed holder 11 is rotated and lowered as absorption of silicon proceeds to produce an elongated monocrystalline rod.  The reaction vessel comprises glass cylinders 1 and 2, separated by the induction heating means, metal end plate 3, carrying tube 13 and metal end plate 4 carrying seed holder 11 and gas withdrawal tube 14. Specifications 745,698 and 826,575 are referred to.

Title: Electric power supply circuits
IPC: H02J7/00
Filed: 1974-06-05
Abstract: 1470453 Converting; supply circuits for TV sets; battery charging systems SONY CORP 5 June 1974 [9 June 1973] 24970/74 Headings H2F and H2H In a power supply circuit, e.g. for a portable TV set 21, and having provision for selecting a chargeable internal battery 3 or an external battery 2 and in which the output from the external battery 2 is regulated by means of a D.C.-D.C. converter including a pulse oscillator 12 having a starting circuit 42, 43, and in which the internal chargeable battery 3 is used without such regulation, an under-voltage device 37 is included to monitor the voltage of the internal battery 3, an electronic switching device 49 being included in the circuit of the under-voltage device 37 so as to open a "sneak" circuit which would otherwise prevent operation of the starting circuit 42, 43 when the common switch for the two batteries 2, 3 is first closed. Operation on A.C. supply.-Contacts A, B, 23, 19 are closed so that the A.C. supply 1 is halfwave rectified by diode 5 and fed via a chopping transistor 7 to the primary of a transformer 6. Transformer 4 supplies a starting voltage for a pulse oscillator using transistors Q1, Q2 which drives a switching transistor 15, in turn coupled via transformer 16 to the chopping transistor 7. The resulting pulsed secondary voltage of transformer 6 is rectified at 18 and passed by diode 20 to the TV set 21. When switch 25 is closed, a further diode 22 provides a rectified supply for charging the internal battery 3. The presence of the charging supply is indicated by a light-emitting diode 27. When the voltage of internal batteries 3 is sufficiently great, Zener diode 40 breaks down, turning on transistor 34 which energizes relay 35 which disconnects the under-voltage indicating light-emitting diodes 37. A further connection between the output to TV set 21 and transistor Q3 provides automatic voltage regulation. Operation on interal battery 3 is achieved by opening contacts A, B, 23 and closing contacts 38, 39. When switch 25 is closed, the internal battery 3 is connected to the set 21 via the relay 35. Operation from external battery 2.-Contacts C, D are closed and 39 open. When switch 25 is closed, the pulse oscillator transistors Q1, Q2 are pulsed via a starting circuit 43, 44, thus pulsing transistors 46 and 41 so as to interrupt the current in winding 6b of transformer 6. The resulting counter e.m.f. is rectified by diode 18 and fed via diode 20 to the set 21 with a further feedback path to the pulse oscillator 12 to maintain oscillation and provide voltage regulation. Transistor 49 is initially non-conductive so as to prevent a "sneak circuit" being formed via the light emitting diode 37, but becomes turned on by diode 50 when the pulse oscillator 12 is working.

Abstract: 406,222. Roads; floors. COWLING, H. W., 1, The Grange, Redhill, Surrey. May 29, 1933, No. 25030. [Class 20 (iv).] A process of surfacing a road or floor consists in preparing a substantially dry and compact underlayer, providing the surface thereof with depressions which are constituted by intercommunicating voids of honeycomb structure and comprise at such surface an area of substantially 30 to 50 per cent of the whole area of the surface, applying an adhesive to this underlayer, and then spreading on to this adhesive a rubber latex composition which is allowed to vulcanize under normal atmospheric conditions. The invention also consists of a road or like surface comprising a layer of stones or like road metal, which have been coated prior to laying with asphalt, tar, or bitumen, and are so laid as to provide the desired honeycomb formation at the upper surface of the layer, and a rubber latex composition disposed on such upper surface so as to fill the voids therein. The underlayer may comprise concrete, with the voids formed at the upper surface thereof either by applying a layer comprising equal quantities of cement-coated stones of 1 inch and ¥ inch in diameter or by compacting into the concrete, before it sets, a layer comprising equal quantities of stones of 1 inch and inch in diameter. Alternatively, a layer of stones, which have been previously coated with 9 per cent by volume of asphalt, tar, bitumen, or mixtures or emulsions thereof and comprises equal quantities of 1 inch and ¥ inch in diameter, is spread and rolled on to a base course. In a further method, a layer of clean hard stones is grouted with cement, tar, or bitumen so as to leave the desired percentage of voids between the stones. The adhesive may comprise tar or emulsions thereof, bituminous emulsion, which may contain rubber latex, or mixtures of these materials in the form of an emulsion. The rubber layer may be reinforced by a metallic mesh, which is placed on the underlayer prior to the application of the rubber composition and is anchored to such underlayer by nails, staples or spikes. If desired, the rubber surface may be consolidated by rolling with a gradually increasing load. A bituminous emulsion may be sprayed or broomed on to the rubber surface before opening the road to traffic.
