Patent GB-382899-A (GB)
Title: Improved manufacture of magnesium
IPC: C22B26/22
Filed: 1932-05-20
Abstract: A process for the production of magnesium consists in reducing at a high temperature magnesia, or dolomite, or a silicate or carbonate of magnesium by silicon and condensing the vapour produced.  The reducing agent may be pure silicon or magnesium silicide or a high silicon ferrosilicon or any appropriate alloy of silicon which may be prepared by reduction of silicates by carbon in the electric furnace. A very intimate pulverized mixture of the magnesia containing substance and reducing agent is compressed and heated in a fireclay or iron retort communicating with an iron receiver in which the reduced magnesium condenses.  The reduction may take place under reduced pressure or in a reducing atmosphere by passing a gentle current of hydrogen through the apparatus or preferably by maintaining in the apparatus a slight pressure of hydrogen or hydrocarbon.  The residue of the reduction is a mixture of silica and magnesia which may also contain small quantities of magnesium silicide and silicon.  By reducing this residue and an excess of silica by carbon in the electric furnace a mixture of magnesium silicide and silicon is obtained which may be employed for the reduction of a further quantity of magnesia.

Title: Improvements relating to track braking apparatus
IPC: B61K7/08
Filed: 1926-06-08
Abstract: 277,093. Westinghouse Brake & Saxby Signal Co., Ltd., (Union Switch & Signal Co.). June 8, 1926. Arresting-grips or friction apparatus on per. manent way; fluid-pressure.-In an electricallycontrolled fluid-pressure operated brake for vehicles of the kind comprising braking bars arranged on the track for engagement with the wheels or other part of the vehicle, the braking pressure is determined according to the positior of a main control switch operating in conjunction with a series of switches responsive to the different pressures to be established and con trolling supply and exhaust valves. The appara tus shown comprises a piston 5 in a cylinder 4 and connected to the braking bars 2, 3 by connections 7. Electrically controlled valves B, E, R are adapted respectively to supply pressure fluid to one side of the piston 5 to apply the brake, to exhaust it from that side to reduce or release the braking pressure and to supply fluid to the other side to disengage the brake members. The magnet of the supply valve B is adapted to be included in circuit with one or other of a series of switches K<1> - - K<4> controlled by Bourdon tubes connected to the cylinder 4 whereby these switches are automatically opened each at a different pressure, for example the limiting pressures may be 20, 40, 60 and 80 lbs. per square inch. A second series of switches L' - - L<4> are adapted to be included in the circuit of the magnet of the exhaust valve E and open respectively at pressures somewhat higherthan those of the corresponding switches- K<1> - - K<4>. If it is desired to establish a braking pressure of say 60 lbs in the cylinder 41 contacts 57, 61 are engaged by the main switch arm 27 whereby the exhaust valve E is closed and the supply valve B opened. When the predetermined pressure is reached the switch K<3> is opened by the Bourdon tube thereof and the valve B is thus closed. If the pressure should rise above, say, 65 lbs. the switch L<3> which is in circuit with the exhaust valve E opens and the pressure is therefore maintained between 60-65 lbs. If it is desired to reduce the braking pressure to say 20-25 lbs., the switch 27 is moved to close the contacts 59, 62 so that the switches K<1>, L<1> are included in the circuits of the valves B, E, respectively; the switch L<1> therefore immediately effects the opening of the valve E until the pressure has fallen to 25 lbs. By the closing of contacts 52, 53 all the pressure controlled switches are cut out and the maximum pressure is applied to the brake. A contact 32 is provided for energizing the valve R to return the brake members to the release position. A simpler form of the apparatus is also described in which only one series of pressure-operated switches is provided, these being selectively included in the circuit of the supply valve B.

Abstract: 565,567. Cleaning metals. DU PONT DE NEMOURS & CO., E. I., and GILBERT, H. N.. Oct. 16, 1942, No. 14502. [Class 82 (ii)] [Also in Group III] Metal articles are cleaned by contacting them with a molten composition comprising one or more alkali metal hydroxides containing dissolved alkali metal amide. The surface of the bath is protected from oxidation either by passing a stream of ammonia gas which may be mixed with non-oxidizing or inert gases, such as nitrogen or hydrogen into the bath or by the use of a floating layer of solid insoluble material thereon such as charcoal or graphite. The bath may comprise sodium hydroxide'with or without diluents such as borax, cyanides, strontium or barium chlorides, and 1-25 per cent by weight of sodamide with or without up to 20 per cent by weight of sodium hydride. After treatment with the bath, the articles are quenched in water. The composition may be produced by the interaction of ammonia with alkali metal oxide dissolved in a fixed mass of alkali hydroxide or by floating a layer of molten sodium on the surface of fused caustic soda and passing in ammonia so that it comes 'in contact with the sodium at the interface between the sodium and caustic layers. If hydrogen is mixed with the ammonia, sodium hydride is also produced in the bath. The cleaning of iron sheet articles and of non- ferrous metals and alloys, such as copper and nickel, is referred to. Specification 557,530 is referred to.

Filed: 1955-05-20
Abstract: 795,822. Printed circuits; etching. MASSON SEELEY & CO., Ltd. May 17, 1956 [May 20, 1955], No. 14630/55. Class 100(2) [Also in Group XXXVI] A method of producing a printed circuit comprises the steps of coating a laminate, comprising a thin metal foil secured to a heat-stable insulating base, with a resistant layer in the pattern of the desired circuit by transferring the layer by heat and pressure from a foil upon which it is carried to the laminate, etching the metal foil away from those parts of the laminate not protected by the resistant layer and finally stripping the resistant layer from the remaining metal foil. The laminate preferably comprises a thermosetting resin base (e.g. a phenol-formaldehyde or a polyester resin) having a thin copper foil secured thereto. The resistant layer, which may comprise polyvinyl chloride and may be pigmented is provided upon a foil of e.g. regenerated cellulose. In one way of carrying out the invention the resist-bearing foil is laid upon the metal surface of the laminate and-subjected to heat and pressure by a press supporting a die having the desired circuit pattern formed thereon so that the resistant layer adheres to the copper foil over the area of the desired circuit. pattern. The exposed area of the foil is then etched away, for example, in a ferric chloride etching bath. After the etching is complete the laminate is washed and the resistant coating then removed with a suitable solvent. In order to increase the thickness of the metal layer upon the insulating base a subsequent plating operation in which the copper is plated with tin and/or lead may be carried out. In an alternative arrangement the pattern on the die is the negative of the desired circuit configuration and the die is used to transfer the negative of the circuit pattern from the resistbearing foil to a piece of paper which is then discarded. The resist-bearing foil is then placed over the laminate and heat and pressure applied to transfer the remaining positive pattern to the laminate. The exposed foil is then etched away and the resistant coating removed as in the previously described arrangement. The invention may be applied to the production of printed circuits on both sides of the insulating base.
