Title: Transformer for supplying polyphase rectifier
IPC: H02M7/06
Filed: 1941-01-06
Abstract: 542,746. Transformers. AKT.-GES. BROWN, BOVERI, & CIE. Jan. 6, 1941, No. 205. Convention date, Jan. 6, 1940. [Class 38 (ii)]  In transformers for feeding polyphase rectifiers in which the anodes operate in pairs in parallel, winding sections feeding pairs of anodes of opposite phase (e.g. a, a1), are grouped with the windings feeding pairs of anodes operating in parallel therewith (e.g. d, d1) and the primary windings of corresponding phase are sub-divided into series-parallel connected series u1 ... u4, Fig. 2, and interleaved with the secondary sections, all the sections being in the form of disc coils. Thus the winding sections form substantially magnetically-independent groups whereby the development of powerful magnetic forces acting on the windings in the event of shortcircuits due to back ignition is avoided.

Title: Improvements in means for removing residual charges from furnace hearths and the like
IPC: F27D25/00
Filed: 1943-01-07
Abstract: 560,129. Removing residual charges from furnaces. CONSETT IRON CO., Ltd., and TOMLINSON, H. V. Jan. 7, 1943, No. 286. [Class 51 (ii)] Residual charges of molten metal or slag are removed from furnace hearths and the like by means of a spoon or scraper operated mechanically by a rotary bar capable of angular and longitudinal movement. The spoon may be operated to bale out metal or slag from any holes in the hearth and pour it down or in front of the tapping hole. The scraper is employed to rub away ridges in the hearth so as to allow metal or slag to flow through a channel or gutter to the tapping hole. Fig. 1 shows a spoon 1 removably mounted on an arm 2 provided with a plate 4 having flanges 5, 6 and 7 on its side, top and back so that it may engage with a flange 10, Figs. 1 and 6, on a rotary radial bar 9 such as the charging-bar of a machine for charging materials into the furnace. The arm 2 is locked on the bar 9 by longitudinal movement of a bar 11 which passes through holes in the plates 10 and 4. The scraper is shown at 14, Fig. 4, pivotally mounted at 13 on a member 12 removably attached to the arm 2. The scraper is secured against rotary movement by a cottar bolt 15 which may engage with one or other of a number of holes provided in the member 12 according to the angular position the scraper is to be arranged relative to the member 12.
Patent GB-431347-A (GB)
Title: Process for husking grain
IPC: B02B3/12
Filed: 1934-01-04
Abstract: Grain is husked by submitting it to the action of a strong salt solution, which may be a solution of a neutral salt such as sodium chloride, calcium chloride, sodium sulphate or the like, in conjunction with dilute acids, e.g. sulphuric, nitric or phosphoric acids or mixtures thereof, or lyes.  A percentage of ten to twenty per cent of common salt is suggested as suitable in the acid or lye which, although dilute, should itself not be below a concentration of two per cent.  The treatment is continued for a slighter shorter time than is necessary to cause colouration at the germ end of the grain. After treatment the grain may be freed from the liquid by centrifuging, washing and polishing.  Very dilute lyes or acids in admixture with salts may be used to wash and neutralize the grain. The time of treatment for husking may be reduced by the addition of salts of organic acids or organic compounds such as ethyl acetate, of oxidizing agents such as hydrogen peroxide, potassium chlorate or perchlorate, chloride of lime, potassium permanganate or bichromate, of reducing agents such as sodium sulphate or of compounds such as alkali nitrates or nitrities or salts of ortho- and pyro-phosphoric acids.  In addition to the treatment with the acids or lyes in strong salt solution the grain may undergo a preliminary or simultaneous treatment with chemicals such as chloroform, ether, acetone, trichlorethylene, benzol or alcohol to dissolve the fatty or waxy substances.  The husked grain may be melted.

Title: Improvements in method of coating objects of iron or steel with aluminium or aluminium alloy
IPC: C23C2/12
Filed: 1931-01-05
Abstract: In coating objects of iron or steel with aluminium or aluminium alloys by dipping, the objects are subjected to a cleansing treatment to remove fatty substances, oxides, and slags, dipped in a molten flux bath containing zinc chloride, an alkali chloride, calcium chloride, and an alkali aluminium fluoride and heated therein so that they can be transmitted to the metal bath without the temperature of the objects falling below the melting-point of the metal.  The fatty substances, oxides, &c. may be removed mechanically or by pickling, and superficial impurities may then be removed by immersion in an aqueous solution or a melt of a salt, such as zinc ammonium chloride or zinc ammonium fluoride, which will convert the oxidic impurities into volatile compounds and, when the objects are dried by heating, will leave a protective salt layer on their surfaces.  The objects are then immersed in the flux bath in which they are preferably kept in rotation or otherwise agitated or subjected to the action of brushes.  The flux bath may contain zinc chloride, sodium chloride, potassium chloride, calcium chloride, and cryolite.

Title: Flying cut-off
IPC: B23D25/04
Filed: 1965-01-06
Abstract: 1,086,651. Flying shears. YODER CO. Jan. 6, 1965 [Jan. 8, 1964], No. 589/65. Heading B3W. A flying shear particularly adapted for cutting moving tubing comprises a doublesided cutter B mounted in a rectangular frame 66 which is reciprocated on guide rods 55 and 56 by the piston rod of a double-acting compressed air cylinder 17. Assuming the frame 66 to be at the left-hand end of its stroke, a pin 81 is held by a latch 83, while high pressure air is admitted to the left-hand end of the cylinder 17. When the latch 83 is disengaged by a solenoid 94, the cutter accelerates rapidly and passes through the tubing T. When the piston is half-way along the cylinder 17, exhaust ports 48 and 49 are uncovered, the supply of high pressure air is cut off and low pressure air is admitted to the right-hand end of the cylinder to decelerate the piston. The return stroke which is also a cutting stroke is made by reversing the air connections to the cylinder 17. The air valves are solenoid operated and the cycle of operation is initiated when the leading end of the tubing operates a limit switch. In order to allow for the finite movement of the tubing during the cutting stroke the cutter B is mounted in a sub-frame 117, Fig. 8, which can move on guide rods 108, 109 in the frame 66. Springs 123, 124 return the cutter to its original position after the cutting stroke. During the cut the work is held on either side of the cutter by split clamps, one pair of which 186, 187 is shown in Fig. 7. The clamps are closed by a fluid cylinder 197 which operates a wedge 179. The clamps are mounted on a carriage which slides on guide rods 163, 164, so that when the clamps engage the material, the whole carriage moves with the material. Springs return the carriage to a position determined by stop nuts 232. Cutter shape.-The cutter B is symmetrical about vertical and horizontal centre-lines and comprises a rounded point 137, Fig. 9 (not shown), a pair of arcuate, concave, outwardly flaring surfaces one on each side of the point each leading to and blending with an arcuate convex surface, followed by a further arcuate concave surface.

Abstract: 571,639. Luminescent materials. COSSOR, Ltd., A. C., WAYE, B. E., and MITCHELL, A. G. Jan. 12, 1944, No. 605. [Class 39 (i)] [Also in Group III] An adherent film of a powder insoluble or only slightly soluble in water is formed on a surface by settling the film from a suspension of the powder in a slightly alkaline solution over-saturated with an inorganic substance which has very low solubility in water and which forms a gelatinous precipitate. The solution may be prepared by mixing a dilute copper sulphate solution with a very dilute solution of caustic soda in tap water. An alkaline solution over-saturated with copper hydroxide is thus produced. Similar processes which result in the production of zinc or aluminium hydroxide which also form gelatinous precipitates may be used. The process is primarily intended for making fluorescent screens and the powder settled is luminescent, such as calcium phosphate or zinc sulphide.

Title: Process for improving the crease- and shrink-resisting properties of textile materials and the product thereof
IPC: D06M13/123
Filed: 1944-01-18
Abstract: Textile material formed predominantly of regenerated cellulose is stabilized with respect to dimensional skrinkage and is rendered resistant to wrinkling, crushing and creasing without impairing its original softness, by treating it with an aqueous solution containing the equivalent of 15-120 c.c. of 30 per cent by weight glyoxal solution and 1/8 to 4 grams of an acidic catalyst per litre of the treating solution, and baking the treated textile material at a temperature of 212-350 DEG  F. for 40-2 minutes so as to effect reaction between the glyoxal and the fibres of the textile material. The treatment may be a plied to fibres, yarns, fabrics, or garments of regenerated cellulose including viscose, cuprammonium and saponified cellulose acetate varieties, or of mixed materials such as viscose-cellulose acetate, viscose - casein, viscose - soya bean protein, viscose-wool and viscose-cotton.  The glyoxal probably forms a cross - linked, long - chain reaction product with cellulose.  In aqueous solution it is present in the form of a hydrated compound known as tetrahydroxy-dioxane.  The acidic catalyst may be oxalic acid, ammonium chloride, ammonium sulphate, or ammonium nitrate. In an example, viscose rayon fabric is impregnated with a solution of glyoxal containing oxalic acid.  It is squeezed, dried on a tenter frame at 180 DEG  F. and then cured in a tenter oven or loop drier oven at 260 DEG  F.
