Patent GB-754554-A (GB)
Title: Improvements in or relating to the production of silicon of high purity
IPC: C01B33/02
Filed: 1954-03-19
Abstract: Silicon of high purity is produced, in a chamber or chambers which have walls resistant to silicon halides, by exposing silicon, which contains impurities, at a pressure between 10 and 7,500 mm. Hg. and a temperature between 1000 DEG C. and the melting point of silicon (1414 DEG C.), to a silicon tetrahalide forming a lower silicon halide, and moving the lower silicon halide in a gaseous state to a place of lower temperature where, with reformation of silicon tetrahalide, pure silicon is separated. The resistant walls may be silicon dioxide (quartz), silicon carbide, or graphite which becomes superficially silicized.  The tetrafluoride, tetrachloride, tetrabromide, or preferably, tetraiodide of silicon may be used, the latter at a pressure at least 65 mm. Hg.  The temperature for conversion may be 1100-1350 DEG C., and that for decomposition at least 100 DEG C. up to 500 DEG C. lower than the conversion temperature.  A single tube or two vessels may be used for the conversion and decomposition, and the lower halide may be conveyed by diffusion, quartz bladed fan, or a carrier gas e.g. rare gas or hydrogen.  The silicon, e.g. 90 : 10 Silicon : iron alloy may be preliminarily purified by hydrochloric and hydrofluoric acid treatments, or by recrystallization from a silver melt.  In a modification, the silicon is first purified by heating with silicon dioxide in vacuum at above 1000 DEG C. to form silicon monoxide gas, which on condensation is converted to a mixture of silicon and silicon dioxide, which is treated with silicon tetrahalide according to the invention, leaving oxidic impurities in the silicon dioxide. The tetrahalide may be produced in situ by action of a halogen on the silicon to be purified at above 300 DEG C., preferably at the temperature of silicon conversion.  In an example, silicon tetrachloride, with or without hydrogen or argon carrier gas, acts on impure silicon at 1200 DEG C. in a first chamber with quartz walls, and the dichloride is decomposed in a second chamber at 1000 DEG C. with deposition of silicon.  The silicon tetrachloride is recycled. The reaction is stated to be Si + Si Cl4 = 2 Si Cl2.

[Also in Divisions B2 and F2] A vibratory conveyer, as described, or a vibratory screen is driven by a mechanism comprising a link 16, Fig. 3, the ends of which are respectively pivotally connected to the conveyer and to an oscillating member 17 pivotally mounted on a framework supporting the conveyer, the pivot axis of the link 16 with the member 17 being slidably movable into and out of alignment with the pivot axis 20 of the member 17 with the framework, for varying the amplitude of the vibrations of the conveyer. The latter comprises three trays 10, 11, 12, Fig. 2, the trays 10, 11 being broad and the central tray 12 being narrow and forming a dribble feeder. The trays 10, 11 are suspended by parallel hangers 13, see also Fig. 1, and the tray 12 is suspended by hangers 14 and supported by a pivoted bar 15. The member 17 comprises ends 18 pivoted to the framework at 20 and interconnected by bars 19 between which extend three columns 25 having slidably mounted thereon trunnion members 26, each tray 10, 11, 12 being connected to a respective one of the members 26 by a link 16. The ends 18 of the member 17 are connected by rods 24 to a pair of eccentrics 23 which are mounted on a shaft 22 driven by an electric motor 21. The members 26 are arranged so that at the lower end of their sliding travel on the columns 25 their pivot axes are in alignment with the axis 20 so that in this position no vibration will be transmitted to the trays 10, 11, 12. The positions of the members 26 on the columns 25 are individually controlled by three mechanisms each of which comprises a rod 27 pivoted to the associated link 16 and to one arm of a bell-crank lever 28 pivotally supported on the framework. The other arm of the lever 28 is connected by a rod (29), Fig. 4 (not shown), to a pneumatic ram 31 operated by valves which may be actuated by a weighing machine which the conveyer is feeding. The upper limit of the movement of each member 26 on the associated columns 25 is controlled by an adjustable stop member 33 against which a projection (34) on the lever 28 abuts as the ram 31 retracts the rod (29), the position of the member 33 being adjustable by means of a control knob 35. The conveyer may comprise a single tray and the rams 31 may be dispensed with, the projections (34) on the levers 28 being spring urged into engagement with the stop members 33.

Title: Improvements in and relating to electric gas blast circuit breakers
IPC: H01H33/08
Filed: 1942-06-15
Abstract: 558,668. Gas-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd. June 15, 1942, No. 8142. Convention date, June 17, 1941. [Class 38 (v)] In a switch wherein the arc drawn is urged by a gas-blast against the edges of spaced, transverse, insulating barriers in an arc chute, the barrier-edges are protected against excessive arc heat by directing there-against an auxiliary jet of pressure-gas, such as air, in opposition to the main blast. Thus refractory barriers are protected against fusing, and barriers of hard fibre or other vaporizable material are protected against erosion and such gas as is produced therefrom is completely burnt in the shoot by the auxiliary air supply. As applied to the switch of Specification 544,017, the barriers 9 are so formed as to provide an air-space 9<SP>1</SP> into each end of which an air-supply from pipe 12 and main reservoir 8 is admitted at 9<SP>11</SP> simultaneously with the main blast through pipe 6. The air escaping from space 9<SP>1</SP> through the slits at the barrier-edges forms a comparatively-cool cushion between the barriers and the arc drawn between the fixed and moving contacts 1, 3. Specification 553,472 also is referred to.

Title: Optical Scanning Head
IPC: G06K7/10
Filed: 1967-02-21
Abstract: 1,155,696. Photo-electric line followers. V¦ZKUMNY USTAV MATEMATICKYCH STROJU. Feb. 21, 1967 [Feb.22, 1966], No.8144/67. Heading G1A. [Also in Division G2] In a scanner for a line follower means are provided to form one image of the part of the line being followed on photo-electric sensing means and a second, enlarged, image on viewing means. The images may be formed simultaneously as in Fig. 9. Light from a lamp 18 is formed into an annular beam by a mask 30 and reflected by an annular mirror 24 through the lens 25 to illuminate the line to be followed. Light reflected from the line passes through a lens 3 and the aperture in the mirror 24 to a beam splitter 11 where one beam is deflected to fall upon an array of photo diodes 4 and the transmitted beam forms upon a viewing screen 7 an image which has been erected by a roof prism 5. The distance of the scanning head from the line can be adjusted manually by a rack and pinion mechanism 33, 35. In modifications, Figs. 2, 8 (not shown) further reflecting surfaces are used to achieve a different spacial arrangement of the light path sensing means 4 and the screen 7. Instead of the annular mirror 24 the line may be illuminated by a reflecting prism, Fig. 6 (not shown), semi-transparent mirror, Fig. 7 (not shown) or lamps carried in a hemispherical dome, which also carries the lens 3, Fig. 5 (not shown). The line may be illuminated from beneath by a fluorescent tube, Fig. 3 (not shown) or a row of incandescent lamps, Fig. 4 (not shown). The images may be formed selectively as in Fig. 11. A mirror 41 is normally biased by a spring 39 into a position where it directs the light from the line on to the sensing means 4. Actuation of the electromagnetic armature 38 moves the mirror 41 into the position shown dotted where it allows the light from the line to pass via the roof prism 5 to form an image of the line on the viewing screen 7.
