Title: Improvements in inorganic bonded reconstituted mica sheet
IPC: C04B28/34
Filed: 1964-01-10
Abstract: <PICT:1056411/C1/1> A reconstituted mica sheet comprises comminuted mica particles and a binder consisting of B2O3, K2O and P2O5 in the relative mol percentages lying within the area defined in the accompanying ternary diagram by the lines AB, BC, CD, DE, EF, FG, GH, and HA.  Mica pulp, comminuted by known methods, and freed of ultra fine and coarse particles, is formed into a wet sheet on paper making apparatus, dried and calendered, and the solution containing the binder applied thereto, e.g. by painting on.  Alternatively, the binder may be added to the pulp or applied to the wet sheet.  The binder constituents may be provided by K2B4O74H2O, KH2PO4, H3BO3, H3PO4 and KOH in aqueous solution.  The treated sheet is dried, e.g. at 89-95 DEG  C. for about 1 hour until the moisture content is less than 1%, removed from the apparatus, and remoistened to a moisture content of 1-10%.  The moistened sheet is pressed at up to 4000 p.s.i., preferably 500 p.s.i. at, e.g. 200 DEG  C. for, e.g. 2 hours, and baked at 560 DEG  C for about 1 hour. Preferably, before baking, the sheet is exposed to a rise in temperature from about 90 DEG  to 175 DEG  C. over a period of from about 8 to 24 hours.  The sheet produced by the process has improved flexural strength, and after two hours water immersion and re-drying, recovers at least 88% of its flexural strength.

Drawings to Specification [Class 82 (i)] [Also in Group XXII] In order to obtain copper alloy, containing 3 or more per cent. of lead, which can be rolled without deterioration, the alloy is cooled unidirectionally, during solidification this direction being preferably normal to the direction of intended rolling. The alloy may be cast against a steel backing and solidification be produced by cold sprays on a conductive side of the mould, which is made otherwise of non- conductive material and which has been preheated to above the melting point of the alloy whereby substantially parallel dendrites are formed normal to said cooled side. A number of different alloys are referred to in some of which the lead varies from 3 to 25 per cent. Another example contains 20 per cent. of lead and 8 per cent. of tin. Other examples contain up to 27¢ per cent. of lead, 3 to 11 per cent. of tin and 0.01 to 5 per cent. of zinc. The cast alloy may be annealed before rolling. U.S.A.

Title: Improved method of preparing inking rollers and printing plates for printing from intaglio plates
IPC: B41F27/00
Filed: 1950-01-23
Abstract: 689,842. Printing. GIORI, G. Jan. 23, 1950, No. 1746/50. Class 100(ii) Inking-apparatus; printing on curved surfaces; printing-surfaces.-Relates to multi-colour intaglio presses wherein a single plate is inked by a number of inking rollers having relief surfaces corresponding to the different colour areas. According to the invention printing plates to the number required for the total run, plus one extra, are made from a matrix which incorporates reference marks; a transparent sheet placed on the extra plate is then marked with the reference marks and with lines defining the areas to be separately inked, the plate is made photo-sensitive, the transparent sheet is re-registered thereon, and the marks are photographed on to the plate and etched; prints from this plate are then made on resilient or resiliently coated inking rollers, one for each colour, and all areas .thereof hot to be printed with the particular colour are cut away e.g. mechanically or chemically. The metal matrix, e.g. made by an electro-forming process, may be engraved with two horizontal lines near its top and bottom edges for uniform registration of the plates in the press; it may comprise a number of identical engravings in which case a transparent film is marked up from one engraving with reference marks (e.g. corresponding to the engraving corners), the colour area boundaries and identifying numbers or letters for these areas, and diapositives are prepared therefrom for photographing on to the remaining engravings (Fig. 4). The inking rollers, made without hygroscopic materials, may be injection-moulded, extruded, or built up of superposed calendered sheets, and may have a circumference greater than the length of the printing surface of the plate so that the effective circumference under normal operating pressure (radius R, Fig. 7) is reduced thereto. Fig. 5 shows a machine for printing an inking roller 8 from a plate 11 carrying the extra markings; the clamps 9, 10 allow for circumferential adjustment of the plate using the two horizontal lines thereon in conjunction with millimetric rules on the borders of the sector 6, which is geared to the roller 8 and to a driving gear 13; the inking roller support 17 has a handwheel graduated scale and index for pressure adjustment. Specification 689,843 is referred to.

Patent GB-803374-A (GB)
Title: Process for the production of lactams
Filed: 1957-01-17
Abstract: Lactams are prepared by reacting g -halogenobutyronitrile or d -halogenovaleronitrile, the carbon atoms of which may be substituted by alkyl radicals containing fewer carbon atoms than the alkyl chain of the nitrile, with ammonia or a primary amine in the presence of water and at elevated temperature.  It is advantageous to effect the reaction at 150-250 DEG  C., preferably at 180-200 DEG  C., and under pressure.  It is also preferred to use an excess of ammonia or amine, e.g. 20-100 mol. of ammonia or amine per mol. of nitrile, and an excess of water, e.g. 20 to 50 mol. of water per mol. of nitrile. The process is best operated by heating the initial mixture rapidly to reaction temperature, or by preheating the components before they are combined.  For example, the nitrile may be gradually introduced into the aqueous ammonia or amine solution heated to reaction temperature.  The process may be operated continuously or discontinuously.  In examples: (1) valerolactam is obtained by heating together d -chlorovaleronitrile, water and ammonia in a silver-lined autoclave, the product being recovered by evaporating the reaction mixture to dryness and extracting with benzene; (2) valerolactam is prepared as in (2) in a V2A steel-autoclave with magnetic stirring; (3) pyrrolidone is obtained by heating together chlorobutyronitrile, water and ammonia in a V4A steel agitated autoclave and recovered by extraction with ether after evaporating the water and ammonium chloride.

The valves B, B<1> are lift valves and may be formed with tubular stems as described in Specification 213,042. The vessels C are provided with outlets c which discharge to the funnels G. The outlet c is arranged in a portion of the vessel which is not directly under the valve B or B<1> when that is open, so that the funnel G need not be placed directly under the valve, and that the drip from the valve when it is closed can be caught in a separate vessel H. The valves are operated by sliding rods d, and cams F on shafts K, K<1> connected by sprocket chains k<1> as described in Specification 213,044. The holders may be arranged around an axis as described in Specification 209,281, when the vessels C have a rotary motion and are shaped accordingly.

Abstract: 1,147,014. Silicon carbide diffusion masking. WESTINGHOUSE ELECTRIC CORP. 12 Jan., 1968 [27 Jan., 1967], No. 1879/68. Heading H1K. A silicon carbide layer is formed on, for example, a silicon body by pyrolytic decomposition of methyl silane or halogenated methyl silanes mixed with an inert gas, and the layer selectively removed to provide a diffusion mask. The masking pattern is produced by oxidizing the entire surface of the carbide layer and providing a photoresist pattern thereon; the exposed oxide is then etched away to leave a thin carbide layer in the window areas, and the system again exposed to an oxidizing atmosphere (e.g. steam/oxygen) to convert the exposed carbide to oxide which is etched away with buffered hydrofluoric acid. It may be necessary to repeat the oxidation and etching steps to penetrate the carbide completely. Boron or phosphorus may be diffused through the mask produced. Phosphorus sources identified are phosphorus oxychloride carried by oxygen and ammonium phosphate carried by oxygen or nitrogen. The mask is effective when formed upon a lapped but unpolished semiconductor surface.
