Abstract: 1,140,172. Lasers. COMMISSARIAT A L'ENERGIE ATOMIQUE. 8 March, 1967 [11 March, 1966], No. 10835/67. Heading H1C. A plurality of crystal laser rods 1, Fig. 3, are optically pumped by ionizing a gas contained in a hollow annular transparent enclosure 6 through which the rods extend, electric discharge in the gas being initiated by breakdown of a spark gap 11 which causes current to pass through an electrode 10 and a metallic casing 9 substantially surrounding the gas enclosure. The general direction of the current is indicated by the arrowed broken lines in the figure, its passage through the metallic casing causing a pinch effect on the plasma created by the gas discharge and thereby localizing the discharge energy away from the walls of the enclosure. The spark gas is insulated from the return current path by an insulating wall 13. In a modification, Fig. 4 (not shown), the spark gap is located within the dimensions of the enclosure. The rods may be of ruby and the metallic casing formed from copper.

Title: Improvements in the manufacture of abrasive articles, such as sandpaper
IPC: C09D161/06
Filed: 1936-04-16
Abstract: 473,619. Flexible abrasive sheets. TENNANT, W. J. (Carborundum Co.) April 16, 1936, No. 10994. [Class 60] In making abrasive articles such as sandpaper a backing of paper or fabric is first coated with a heat-hardenable resinous liquid or a resin solvent such as a phenol or aldehyde, e.g. furfurol, and then with a heatreactive resin such as a phenolic resin, metastyrene or polyvinyl compounds, in the form of a dry powder. The materials of the first coating are so selected as to react with the powdered resin on heating. The abrasive grains may be applied admixed with the powdered resin or before, in which case they may be moistened, or after the latter is applied. The resinous liquid may be a liquid resin or a solution of a solid resin, e.g. an oil-modified phenol-formaldehyde resin dissolved in toluol. Inert fillers such as powdered flint may be incorporated in the resinous liquid or the powdered resin and a flexibilizing agent such as tricresyl phosphate may be added to the resin or resin solvent. The backing is preferably non-absorbent, e.g. sized paper, metal sheets or glue-coated paper or cloth. A resin solvent may be applied after the powdered resin, especially where the coated product is afterwards roll-cured as described in Specification 467,111. Specification 440,569 also is referred to.
Patent GB-454947-A (GB)
Title: Improvements in refractory articles and the method of making them
IPC: C04B35/107
Filed: 1935-04-09
Abstract: A cast refractory material suitable for glass tank and similar furnaces is formed of alumina and a smaller percentage of silica, and consists principally of corundum crystals and an intercrystalline glass.  The crystalline portion may be corundum and mullite in the proportion of at least two to one.  The refractory is made by melting the raw materials consisting essentially of alumina and from 5 to 30 per cent, preferably not more than 8 per cent, of silica casting the molten mass, and cooling the casting rapidly through the stage at which the crystallization of mullite would result, i.e. from 1810 DEG C. downwards for 50 or 100 degrees, but preferably down to below the point of solidification, e.g. to about 1200 DEG  C.  Fusing may be effected in an electric furnace consisting of a water-cooled unlined iron shell.  Fusion is effected initially by the heat from a carbon train between two or more electrodes, but after a bath of molten material is formed, the resistance of the fused material is used to supply the heat.  The material is fed in gradually and the electrodes are raised as the fused mass is built up.  The furnace may be adapted either for tapping the molten material out through the side, or it may be arranged to be tilted so as to pour the material into the mould, in which case an iron apron may be provided to prevent molten material spilling into the water-cooling system.  Specification 265,847, [Class 22], is referred to.

IPC: B22C1/24
Filed: 1918-07-06
Abstract: 120,706. Hamelius, E. July 6, 1918. Core materials.-In order to give greater cohesion and less porosity to cores made of white sand, about 4 per cent of litharge is added to the linseed oil to form the agglomerating material. The agglomerating liquid is intimately mixed with the sand by repeated siftings so that each grain of sand is brought into contact with the air to facilitate the fermentation of the liquid. The use of flour, resin, dextrin, and the like is thus dispensed with.
