Title: The lamination of material
IPC: H01F41/02
Filed: 1965-01-18
Abstract: 1,040,007. Making magnetic cores; jointing. SIEMENS & HALSKE A.G. Jan. 18, 1965 [Jan. 22, 1964], No. 2207/65. Headings B3A and B3V. A method of securing together magnetic core laminations of a coil or transformer comprises forming a stack of the laminations in their hard-rolled state, securing the laminations together by a layer of metal which is not continuous about the axis of the stack and is bonded to the edges of the laminations, the metal being the same as that of the laminations or such that it does not set up thermal stresses in the laminations, and softening the metal of the stacked laminations by heat treatment. In an embodiment, Figs. 1 and 2 (not shown), the laminations are stacked in bundles 1 separated by paper or pasteboard layers 2, and are secured together by a clamp passing through an aperture in the laminations. Cover strips 4 are applied along the stack, which may be ground, sand-blasted or etched externally before application of the strips. The securing metal layer is then applied between the strips 4 by spraying (Fig. 2) or vapour coating in a vacuum, after which the strips 4 and layers 2 are removed before the bundles 1 are furnace annealed. If the laminations in the bundles are separated by layers of insulating powder adhered to the laminations, only the corners of the bundles are sand blasted and coated with metal.

Title: Improvements in or relating to dust collectors or separators and the like
IPC: B04C1/00
Filed: 1924-01-28
Abstract: 223,786. Davidson & Co., Ltd., and Whitmore, J. Jan. 28, 1924. Density separators.-A separator of the cyclone type has a vortex chamber 6 with a tangentia inlet 11 and an exhaust passage 4 for the purified air; a tangential dust outlet 7 is arranged at any desired point on the periphery of the vortex chamber and is connected to a dust collector or settling chamber 9, preferably of the type described in Specification 196,537. A fan 2 is arranged to draw air through the separator, the exhaust passage 4 of the separator forming the inlet of the fan. The pipe 10 for pure air from the dust collector 9 may also be led to the fan inlet. The vortex chamber may have a circular section instead of a volute form as shown in Fig. 1, and may have stationary vanes to impart the whirling motion to the current of air. In the modification shown in Fig. 3, the separating chamber has an axial inlet 11 and the whirling motion is obtained by means of paddles 14 mounted on an extension of the fan shaft. Stationary vanes 15, Fig. 4, situated in the exit passage 4, neutralize the whirling effect produced in the separating chamber; the vanes are arranged in the form of a cone. The discharge side of the fan may be connected to the inlet of the separator and the current of air may pass from the separator volute to a contrary volute for the purpose of rectifying the flow, and thence to a chimney for discharge. In another modification the vortex chamber 20, Fig. 6, is partly volute and partly circular in section, and the axial inlet 22 contains a helix 21. The whirling motion may be obtained by means, of passages 23, Fig. 8, arranged tangentially to the circular inlet. In the arrangement shown in Fig. 12 the fan 28 exhausts from the chimney 18 and discharges into the same chimney at a higher level, the two levels of the chimney being separated by a damper 29. When the fan is not in use the damper is opened and the dust-laden air passes up the chimney.

Patent GB-692649-A (GB)
Title: Improvements relating to combination toilet bars or cakes
IPC: C11D10/04
Filed: 1951-01-30
Abstract: A saponaceous toilet bar or cake consists of at least 60 per cent by weight of anhydrous water-soluble higher fatty acid soaps and, dispersed throughout, water-soluble salts of higher fatty acid monoglyceride monosulphates in an amount sufficient to disperse lime soaps generated during use of the bar or cake as a toilet soap in hard water, but such that the ratio by weight of the monosulphate salts to fatty acid soaps does not exceed 0.5 : 1.  The soaps may be derived from the usual fatty oils, waxes and fatty acids, mixtures of tallow and babassu nut oil, and tallow and coconut oil respectively being exemplified.  The monosulphate salts may comprise the alkali metal, amomonium and amine salts. These may be derived from hydrogenated fatty materials, and may be prepared by the interaction of such components as glycerine, fatty oils or fatty acids, and an excess of a strong sulphonating agent.  The products are neutralized with a neutralizing agent and dried, and contain a large proportion of inorganic salts such as sodium sulphate.  The bulk of the latter must be removed, such as by solvent extraction.  Minor proportions of the inorganic salts. up to 10 per cent, may be tolerated.  The amount of the monosulphate salts in the compositions is preferably in excess of the theoretical amount required for complete scum dispersion; 10 to 30 per cent and preferably 15 to 25 per cent of the weight of the total solids is specified.  The combination bar or cake is preferably made by a modified soap milling and plodding process, the moisture content being kept within limits and correlated with the temperature during plodding.  The mixture of soap and monosulphate salt is milled, the resulting chips plodded and the bar extruded from the plodder cut into suitable lengths.  The moisture content is kept within the limits of 5 to 15 per cent, and the temperature during plodding is correlated with the moisture content within the range of 100 DEG F for 15 per cent p  moisture content and 135 DEG F for 5 per cent moisture content.  The bar or cake has usually a pH of between 9.5 and 10 in a 0.5 per cent concentration in hard water.

Title: Improvements relating to the manufacture of materials comprising mineral wool
IPC: C03C25/143
Filed: 1942-02-20
Abstract: In forming mineral wool from furnace slags, natural rock and glass by the steam-jet fiberising method, a solution or emulsion of the component of a synthetic resin is injected or entrained into the steam line so that the resin is synthesised simultaneously with the formation of the fibres and distributed uniformly thereon.  The product may be subsequently baked. Suitable resins include urea-, thiourea-, cyanamide-, dicyandiamide-, phenol-, cresol-, or amino-triazine-formaldehyde, and alkyd resins, modified or not with higher fatty acids or alcohols.  Starch, glue, casein, gelatine, soya- or carob-bean flour and pectin may be injected into the steam either separate from or mixed with the resin components. Water-repelling agents, e.g. paraffin wax, petroleum resin, animal, sperm or tar oils and plasticizers, e.g. dibutyl or diamyl phthalate, tricresylphosphate and oil-modified alkyd resins, hardening agents, e.g. hydroxylamine and hydrazine, catalysts, fillers, e.g. clay, chalk, diatomite, granulated cork, and dust or bentonite, and aqueous emulsion of bitumen or asphalt may similarly be added. The product may be moulded or formed into felts, sheets, slabs, bricks and pipes for thermal and acoustic insulation, heat refractories and filters, and may be reinforced by perforated sheet metal, wire netting, asbestos sheet or scrim cloth.  They may be sprayed with water, steam or solvent before shaping.  A tube may be made by placing a layer of the moistened animal wool on a sheet of reinforcing material, rolling over a core, removing the core and drying and baking.  In an example starch paste is emulsified with a petroleum resin and mineral oil to which urea and formaldehyde solution are added and the mixture is injected into the steam used to fiberize molten slag.  The product is granulated and used as a moulding powder by mixing with water to form a dough which is packed into moulds, dried and finally cured.
