Title: Improved process of and apparatus for the gasification of difficultly gasifiable metallic or non-metallic elements and compounds
IPC: C22B5/16
Filed: 1951-09-20
Abstract: <PICT:0728286/III/1> A process for the volatilization of metallic and non-metallic elements and compounds, especially oxides, which are difficult to volatize, comprises introducing the materials through a hollow electrode into a gasification chamber surrounded by an electric arc formed between the hollow electrode and a co-axial counter-electrode, maintaining an energy density of at least 100 kW. per litre of reaction space in the gasification chamber and removing the resultant gases through the cylindrical sides of the electric arc.  In the form shown, an arc is struck between an axially movable hollow electrode 1 and a counter-electrode 11 and the material 10, to be volatized, passing down the hollow electrode 1, is liquefied in the chamber 18 and volatized as it joins the "mother" drop 31.  The vapour passes out between the arc columns 19 and mixed, at 27, with a rotating stream of gas which enters the system at 24.  The rotating gas/vapour mixture passes upward through the pipes of a spiral cooling system 21 where the vapour may condense into small particles and pass out with the gas at 25 or in some cases, e.g. of complex ores, a fractionated condensation may take place at 27 and the fractions, flung outwards by the rotating gas, pass out at 26.  In the case of metallic vapours, oxygen may be fed into the chamber formed by the cooling system and the resultant metallic oxide passed out with the gas 21.  An image of the chamber formed by the arc may be projected, via a lens system 28, on to a screen 29.  The counter-electrode 11 may also be hollow and may be used for introducing materials to be volatized.  According to an example, finely grained silicic acid, introduced at 10, is volatized at 3,000 DEG  C. and the hot SiO2 gas formed in chamber 18 is suddenly condensed at 27.  The condensate in the form of silica particles of 0.01 to 1 micron size leaves at 25 in suspension and is separated.

Title: Improvements in and relating to electric switching devices actuated by bimetallic elements
IPC: H01H1/08
Filed: 1952-09-05
Abstract: 717,017. Thermal switches; switch contacts. GENERAL ELECTRIC CO. Sept. 5, 1952 [Sept. 6, 1951], No. 22426/52. Class 38(5)  In a switch having a bimetallic element 14 carrying a contact 15 co-operating with a fixed contact 12. means are provided for wetting the contacts with mercury. In Fig. 1. the switch has a sealed envelope 1 with a reservoir portion 2 containing a pool of mercury 3, the envelope being filled with gas, such as hydrogen or argon, under pressure. The fixed contact 12 has an extension 13 dipping into the mercury and the surface of the contacts 15, 12, and the extension 13 are made wettable by mercury, e.g. by plating them with platinum, nickel or copper. When the bimetallic element is heated by the current flowing through it or by the surrounding medium, it moves contact 15. away from the contact 12. Initially the mercury on the contacts is stretched into a neck 3b, Fig. 2b, and maintains the circuit between the contacts. Then as the separation of the contacts increases the neck 3b breaks and contracts back into the puddles 3c, 3d, Fig. 2c so giving a quick break of the circuit. This 'action is stated to provide relatively long closed and open periods so rendering the switch suitable for the control of flashing signals. In a modification, Fig. 3 (not shown) the fixed contact is grooved and the extension is U-shaped so as to provide a more copious supply of mercury to the contacts by increasing the capillary action. In this arrangement the moving contact is formed as a U-shaped wire on which the mercury forms a bead. The bimetallic strip may be arranged so that the contacts are opened in response to a fall in temperature. Specification 543,935 is referred to.

Abstract: 316,189. Carborundum Co., Ltd., (Assignees of Martin, H. C.). July 24, 1928, [Convention date]. Compositions containing abrasive material and artificial resins.-A composition for the manufacture of abrasive articles, comprising abrasive granules and powdered synthetic resin, is mixed at a temperature below about 70‹ F. to avoid gumming of the resin, which would result in a non-uniform mixture. The mixture is cold pressed and baked. The abrasive material may consist of silica, garnet, silicon carbide, fused alumina, magnesia or aluminium silicate, or glass, and the resin may be a phenol condensation product. The abrasive granules may be first wetted with furfurol and then mixed with the powdered resin, some of which becomes attached to the granules so that the mixture is workable at temperatures below that at which the resin becomes gummy. The mixing may be effected in a room automatically kept below the critical temperature by a thermostat which actuates a refrigerating system if this temperature is exceeded, and as excessive moisture present in the air will condense on the pipes of the refrigerator, the humidity of the atmosphere will also be controlled. The mixing temperature may be as low as 48‹ F. The temperature of the mixture may also be controlled by water jackets. The mixture may comprise 900 grams of abrasive, 100 grams of resin and 10c .c. of furfurol. Specification 225,436 is referred to.

Abstract: 517,794. Catalysts. SYNTHETIC OILS, Ltd., and MYDDLETON, W. W. Aug. 6, 1938, No. 23302. [Class 1 (i)] Reduced metal catalysts for hydrocarbon synthesis are protected from oxidation by dowsing them after reduction in an organic liquid containing hydroxyl and/or carbonyl groups, which effect strong adsorption of the liquid by the catalyst. Suitable liquids are cyclohexanol, cyclohexanone, and their methyl derivatives, also a synthetic hydrocarbon oil to which 10 per cent. of one of those liquids has been added. The boiling point of the liquid is preferably between 100‹C. below and a few degrees C. above the temperature at which the catalyst is to be used. The freshly reduced catalyst is immersed in the liquid after cooling to below 100‹C. ; after draining surplus liquid is removed by blowing with an inert gas. When required for use the catalyst is heated in an inert gas or in the reaction gas to remove the liquid.
