Abstract: 511,830. Endless-belt conveyers; roller-way conveyers; rolling discs. KRONPRINZ AKT.- GES. FUR METALLINDUSTRIE. Jan. 14, 1939, No. 1335. Convention date, March 9, 1938. [CLass 78 (i)] [Also in Group XXII] In order that a workpiece may be turned during conveyance about an axis substantially perpendicular to the direction of conveyance, the parallel conveying bands or rollers are driven at different speeds. The workpiece d Fig. 1, is conveyed by parallel bands a, b and c and is engaged by a pin upon the central band. If the band a is ' driven at the lowest speed, the band c at the highest speed, and the band b at the mean speed, the workpiece will be rotated in the direction of the arrows and will take up successively the positions shown by broken lines. The central band may be dispensed with, and endless bands pressed into contact with the workpieces may be provided above them in order to assist conveyance. When live-roller tracks are used, two rows of rollers may be provided below the workpieces, or two rows of rollers above and below the workpieces. One of these rows of rollers may be dispensed with. A machine for rolling out thick discs of small diameter repeatedly in different directions to obtain thinner discs of considerably larger diameter is shown in Figs. 9, 10 and 11. Between the roll housings A, B, Fig. 9, are mounted two upper and two lower rows of positively driven rollers 4, 5, Fig. 11. These rollers are journalled in frames 1, 1<1>, 2, 2' supported by cross-members 8, 12 along which they can be moved by screw-and-nut mechanism 18 in order to vary the distance x. The members . 8 can be raised and lowered by screw-threaded spindles 9 in order to vary the distance y. The rollers 4 are driven by a motor 19 at the same speed as the rolls through chain-and-sprocket gearing, but the rollers 5 are driven at a greater or less speed through similar mechanism and a regulating gear 20. The entrance and exit rollers 4<1> at each side are driven at the same speed as the rolls. The movement of the discs is restrained by bars 28.

Title: Methods of forming silicon and silicon formed by the method
IPC: C30B25/02
Filed: 1961-01-13
Abstract: Monocrystalline silicon is formed by the thermal reduction of one or more halogencontaining silicon compounds by passing said compound or compounds together with hydrogen over a monocrystalline body of silicon, the surface of which is heated to a predetermined temperature, hydrogen halide being added to the reaction mixture prior to its passage over said body in an amount such that the equilibrium temperature at which no silicon is deposited from the reaction gas and below which previously deposited silicon is reconverted to the gaseous phase lies not more than 200 DEG C. below said predetermined temperature. Halogen-containing silicon compounds mentioned are SiCl4, SiHCl3, SiH2Cl2, SiBr4 and SiHBr3, while hydrogen halides mentioned are HCl and HBr.  The hydrogen halide preferably contains the same halogen as the silicon compound.  The hydrogen halide may be formed by partial reaction of the halogen-containing silicon compound before the gaseous mixture is passed over the silicon body, e.g. by adding pure water to the silicon compound or by partially subjecting a mixture of the silicon compound and hydrogen to a high-voltage electrical discharge. Alternatively hydrogen halide may be added to the spent gas from a previous reaction in which silicon was formed by decomposition of a halogen-containing silicon compound, such spent gas already containing some hydrogen halide formed in the reaction.  Preferably the conditions are so arranged that the equilibrium temperature is above 900 DEG C.  Specifications 809,250 and 880,559 are referred to.

Title: Method for manufacturing insulation for high tension devices
IPC: H01B17/28
Filed: 1977-01-14
Abstract: During the production of a tubular insulating body consisting of insulating film layers and metal foil layers, which are placed one on top of the other alternately, for high-voltage units, a continuously fed insulating film strip (3) and a metal foil strip (1) which is inserted in sections between the insulating film layers are wound. In this case, the metal foil strip is provided in a strip material weakening station (7), before said metal foil strip runs into the winding, with weakening regions which are located transversely with respect to the strip and are spaced apart from one another. In order to achieve sections of specific length of the metal foil strip and their arrangement at specific points in the winding, the metal foil strip is fixed in a stop station (6) at specific points in time and for a predetermined time duration. In this case, it tears along one of the said weakening regions. Once the predetermined time duration has elapsed, it is drawn into the winding again, a winding section resulting in which there is no metal foil between the insulating film layers. <IMAGE>

Title: Improvements in or relating to the hardening of dye-absorptive hydrophilic colloidallayers

Abstract: 664,597. Hardening gelatine blank films. TECHNICOLOR MOTION PICTURE CORPORATION. Jan. 21, 1949 [April 3, 1948], No. 1751/49. Class 98 (ii). [Also in Group V] The dye-absorptive hydrophilic colloid layer of a blank film is hardened prior to dye transfer thereto by subjecting the layer to the action of an aqueous chromic salt solution containing 25-70 per cent of the green form of chromium and 75-30 per cent of the purple form of chromium and thereafter washing out unreacted chromic salts. Typically an aqueous chrome alum solution containing 52.5 grams per litre, of which 60-65 per cent is of the green form of chromium, is prepared either by mixing appropriate quantities of 100 per cent purple chromium alum, prepared by dissolving the alum in ice-cold water, and of 100 per cent green chromium alum, prepared by boiling chrome alum solution for half an hour, or by heating chrome alum solution to, say, 190‹ F. until sufficient of the green form is present, the final solution being adjusted to pH 3.5 by the addition of ammonia. The blank film is immersed in the hardening solution at 70‹ F. for about 1¢ minutes followed by washing for 1 minute. To avoid depletion of the green chromium in the solution adjacent the film the hardening solution is agitated, as by continuous movement of the film therethrough, and the overall concentration is maintained by periodic additions of the appropriate amounts of the green and purple chrome alum solutions, as determined by colorimetric tests on the solution. Specification 484,411 is referred to. The Specification as open to inspection under Sect. 9 states that a chrome alum solution containing 5.25 grams per litre may be used. This subject-matter does not appear in the Specification as accepted.
