Title: A new and improved process for the treatment of chromium ores
IPC: C22B34/32
Filed: 1937-06-07
Abstract: An intimate mixture of finely divided chromium ore and lime or calcium carbonate is calcined in an oxidizing atmosphere, say at 1400 DEG  C., and the product treated under pressure with water and carbon dioxide to bring chromium compounds into solution. Preferably the calcined product is ground wet in a series of mills in counterflow to a stream of water, a light pressure of carbon dioxide being maintained.  The carbon dioxide may be obtained from the flue gases of the calcining furnace when limestone is used. When the pressure is 1-3 ats. calcium bichromate is formed, but at 6 ats. chromic acid begins to be produced.  The solution of chromium compounds, containing also calcium bicarbonate, calcium aluminate, and calcium silicate is boiled, with or without pressure, to precipitate first calcium carbonate, and then aluminate and silicate, whereafter the pure chromium compounds are recovered by evaporation and crystallization.  In the calcining step, rather more than sufficient lime is used to combine with the chromium, aluminium and silicon contents of the ore, and the ore-lime mixture is preferably worked up with water into porous bricks which are then calcined in a tunnel kiln.  The residue from the treatment of the calcined product with water and carbon dioxide may be treated to extract its iron and precious metal contents.ALSO:Chromium is removed from ores to obtain a concentrate of their iron and precious metals contents by calcining the ore with sufficient lime or limestone to combine with the chromium, aluminium, and silicon contents thereof and then treating the calcined product under pressure with water and carbon dioxide to bring the chromates, aluminates, and silicates formed into solution. Preferably the calcined product is ground wet in a series of mills in counterflow to a stream of water, a light pressure of carbon dioxide being maintained.  The residue from the treatment of the calcined product may contain metals of the platinum group, which may be recovered in known manner.

Abstract: 850,981. Transistors. STANDARD TELEPHONES & CABLES Ltd. (Nippon Electric Co. Ltd.). May 16,1958, No. 15796/58. Class 37 A method of making a transistor comprises forming a region of one conductivity type on a body of silicon of a different conductivity type, depositing a layer of germanium of said different type on the region, and heating to produce interfacial diffusion between the layer and region. In the embodiment a body of N type silicon after acid etching, washing, and drying, is placed in a quartz crucible with a piece of aluminium and heated for an hour at 1200‹C. in an inert atmosphere. The superficial.P type layer formed in this diffusion process is then etched away from all but the top surface of the body and the etched surfaces masked with wax or lacquer. Germanium is then applied over the top surface around a metal mask to form a layer 5 (Fig. 1) provided with an aperture 6. After removal of the masking materials the assembly is heated at 1200‹C. in an inert gas for an hour to intimately bond the germanium and silicon layers. Pointed electrodes 7 of gold antimony alloy and 8 of aluminium are afterwards applied to the germanium and silicon layers respectively and a "Kovar" (Registered Trade Mark) plate soldered to the body with a gold antimony solder. The layers, which in operation serve as emitter and base region respectively, are preferably about 10Á thick. The transistor has the advantages of the high collector impedance and temperature stability associated with silicon transistors combined with the high emitter efficiency of the germanium transistor.

[Class 35] A coil of strip form for the rotor of a dynamoelectric machine, comprises a number of separate members 1, 1a, 2, 2a, so jointed together by a number of interfitting but non- interlocking projections 3 on each member, which projections have co-operating edges 4 parallel to the axis QO of the machine, so that the centrifugal force acting to force apart the side members 2, 2a of the coil will be resisted by the engagement of the edges 4 without any tendency to force the end members 1, 1a apart. As the coil is of helical form, the adjacent ends of members 1 and 2 are in different planes, that end of member 1 being extended to form a connecting piece 7 which may be flexible or laminated. Some windings may be of greater width than the remainder to form cooling fins. Insulating washers provided at the coil ends may be made from members with their ends jointed in a similar manner.
