Title: Method of producing a silica coating from an organic resin
IPC: H01L21/316
Filed: 1972-06-29
Abstract: 1385982 Silica coatings THOMSON-CSF 29 June 1972 [29 June 1971] 30593/72 Heading ClA [Also in Divisions H1 and C3] A patterned SiO 2  coating is applied to a substrate by depositing thereon a thin film of resin polymer of formula (R.SiO 3 H) wherein R is an organic radical, irradiating with electrons to define the required pattern, and thermally treating the substrate in an oxidant atmosphere of, e.g., O 2 +N 2  or Ar at 500-1000 C. for 2 hours. The resin is preferably a polyalkyl silane using methyl, ethyl, or vinyl radicals; e.g. polyvinylsilane, polyvinylsiloxane, polyvinylsiloxanol and is deposited from solution or aerosol spray on a rotating substrate, electronically bombarded, and treated with solvent or thermal etchant to remove unirradiated parts. Polyvinylsilane may be produced by hydrolysis of vinyl trichlorosilane with water agitated in excess ethyl ether at 0-5 C., extraction of unpolymerized resin in ether, polymerization with ammonia, rinsing and drying, and concentration to powder by evaporation in vacuo; after which it is dissolved in a solvent, e.g. isopropyl alcohol, cetane, aromatic carbide, for deposition.

Abstract: 244,915. Hall, L. Dec. 24, 1924. Melting-pot furnaces. - Comprises detail improvements in furnaces for type, stereo, babbit, and like metal. For agitating the metal two propellers 13, mounted one above the other, are rotated in opposite directions. The propellers are carried by concentric tubes 14 geared together at the top for rotation by a shaft 17. Mounted within the tubes 14, and thus protected from mechanical injury, are the tube 20 carrying the outlet valve 19 and within it the beat-sensitive member 30 of the automatic gas regulator 29. The valve 19 is operated by means of a screw thread at 21 and a handle 23. The cover 32 of the furnace which carries the valve rod and the agitating-mechanism is rotatably adjustable to bring the handle to convenient working-positions. The hot gases after flowing over the bottom of the pot enter an annular chamber 3 in the furnace body and are thence directed by the dome 10 over the surface of the metal.

Abstract: 299,472. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Hansell, C. W.). Oct. 28, 1927, [Convention date]. Directive signalling.-A directional array of aerials comprising separate sections 20, 22, 24, Fig. 2, are fed from a power supply 16 through 'lines 30, 32, 34, the effective electrical length of which can be varied through slidable connection points, (a) so as to shift or " warp " the direction of radiation and (b) to focus the radiated beam. By moving the junction point between the supply 16 and the lines 30 and 34, the phase relation of the currents in the sections 20 and 24 is altered and the directional characteristic of the aerial as a whole is warped to one side or the other. Similarly by adjusting the length of the line 32 feeding the central segment 22, the radiated beam can be focused. Fig. 6 shows one method of altering the effective electrical length of the feeds. Successive pairs of feed-lines are wound on a series of rollers 80 - - 86 mounted on a central shaft and having progressivelyincreasing diameters. Alternatively the feeders for the outer aerial segments are wound in different directions on one system of rollers, whilst the feeders for the central section are wound on another set of rollers. Suitable means are provided for taking-up any slack in the feed lines.

Title: Improvements in watch winding device
IPC: G04B3/06
Filed: 1945-11-21
Abstract: 604,034. Winding mechanism. HILL, C., and JOHNS, C. K. Nov. 21, 1945, No. 31373. Convention date, Nov. 27, 1944. [Class 139] A watch winding device comprises in combination with the crown forming a driving element, a driven member having a stem for attachment to the winding shaft of the watch, and a friction member in driving relation with the crown and in frictional engagement with the driven member, both of said members being housed in the crown. As shown in Fig. 1 the winding device comprises a plate 13 which rests on the bottom of a crown 22 and has a stem 11 which is screwed on the winding shaft 10 of the watch. The driven plate 13 has, projecting therefrom, one or more studs 14 which engage with corresponding holes or depressions 15 in a domed friction disc 16 which is in frictional engagement with the plate 13 and is attached to a driving plate 24 which is fixed to the crown 22 knurled at 26. In operation the crown 22 is rotated and this rotation is transferred by way of driving plate 24, friction disc 16, driven plate 13 to the winding shaft 10 so winding the mainspring. When the mainspring is fully wound continued rotation of the crown 22 results in the friction disc slipping over the plate 13 and an audible warning is given by the " clicking " action of the projections 14 in the holes or depressions 15. It is obvious that the friction area of the disc 16, i.e. the area in contact with the plate 13, depends on the thickness of plate used, Fig. 7. In another embodiment, Fig. 3, the crown 35 is turned the other way up and the driven plate 41 is supported by a keeper plate 37 which is a force fit in the open end 36 of the crown 35. The friction disc 42 is attached directly to the crown 35 and no driving plate is used. In another modification, Fig. 6, the friction disc 50 has two small horizontal projections 48a which are loosely received by two vertical channels in the crown. In still a further modification, Fig. 8, the friction disc is replaced by a substantially circular wire spring 66 which surrounds the driven plate 63 and whose ends are held in openings 67 of the crown. The plate 63 has two straight sides and two curved sides as shown to allow for slipping when the mainspring is fully wound.

Title: Synthesis of finely divided oxide powders
IPC: C01F7/302
Filed: 1964-08-04
Abstract: A continuous vapour phase process for the preparation of finely divided refractory oxides of metals or non-metals comprises reacting O2 and a metal or non-metal halide (including oxyhalide) vapour in a stream of hot plasma inert to oxidation; maintaining the temperature of the reaction mixture sufficiently high to prevent formation of solid oxide in the zone in which the oxidation reaction is initiated; quickly cooling the reaction product, thereby precipitating the oxide in finely powdered form; and recovering the desired oxide powder from the reaction product. The halide and the oxygen, preferably in molar ratio of 1 : at least 2, may be pre-heated before entering the reaction zone in which a high density plasma stream of extremely high temperature and formed of, e.g. A, N2 or O2, is used.  The temperature must be kept above the precipitation temperature of the oxide throughout the reaction zone.  The product discharged is cooled, e.g. by allowing it to expand into the atmosphere with or without entrainment of cooling gases, e.g. cold product gas. Alternatively cold product gas may be injected into the reactor exit. Specified starting materials include the chlorides, fluorides, bromides and oxychlorides of Si, Ti, Al, B and Sb, and SiBrCl3. Oxides of Cr, Be, Zr, Co, Ni, Cd, Mo and V may also be produced.  In the examples SiO2 and TiO2 are produced from SiCl4 and TiCl4 respectively.
