Title: Electron-permeable window
IPC: H01J33/04

Abstract: 833,194. Cathode ray tubes. NATIONAL CASH REGISTER CO. Oct. 15, 1958 [Dec. 23, 1957], No. 32912/58. Class 39(1). An electron-permeable window is made by securing a foraminous matrix 30 in a mount 27, 31, cleaning and drying the mounted matrix, filling the openings in the matrix by a coating of sodium bentonite gel dispersed in distilled water, evaporating the water and baking the remainder of the coating to form a thin gas impermeable ceramic film over all the openings and thereafter sealing the matrix to the mount and the mount in the tube by suitable sealing compounds. An electron beam may be directed through such a window on to a moving sensitized medium. This medium, of conductive, or a conductive plate behind the medium, may be given a positive potential to attract electrons through the window, the matrix of which is preferably formed of a conductive material such as metal.

Title: Improvements in or relating to sintered bearing metal
IPC: C22C32/00
Filed: 1955-11-17
Abstract: Sintred bearing metal is made by a powder metallurgical process from a mixture comprising at least 50 per cent Cu (60-325 mesh) and 0.25 to 15 per cent of hard particles of aluminium oxide.  The remaining metallic ingredient may be Zn up to 45 per cent, Ni up to 49 per cent, Pb up to 30 per cent, Al up to 15 per cent or Fe from 1 to 11 per cent, or, when there is more than 70 per cent Cu, it may be Su up to 18 per cent.  The mixture may also contain 1 to 3 per cent Si, small quantities of Mn, Be, Co and P, up to 6.5 per cent finely divided graphite (80 mesh or finer) and 0.3 to 2 per cent of a die lubricant comprising powdered zinc stearate or stearic acid.  The aluminium oxide may be in the form of fused alumina, "Turkish emery," corrundum or tabular corundum, and may be in the form of 100 to 600 mesh powder.  The mixture may be briquetted at a pressure of 20,000 to 120,000 pounds per square inch and then sintered in an inert atmosphere for 4 to 120 minutes at a temperature of 1300 to 1950 DEG F.  The inert atmosphere may comprise H, a mixture of N and H or methane dissociated NH3, a mixture of 20 per cent CO, 3 per cent H, and 77 per cent N, or a mixture of 1.5 per cent CO, 1.5 per cent H, and 97 per cent N.  After sintering, the product may be subjected to a solution heating for 1 to 8 hours at 600 to 1400 DEG F., in an inert atmosphere, or to an initial heating for 5 hours at 1400 DEG F. in an inert atmosphere, a water or oil quench, and to a second heating for 5 hours at 600 DEG F.  Instead of briquetting under high pressure before sintering, the powder may be loosely filled into a mould and may contain a relatively small amount of one ingredient (e.g. Sn) having a lower melting point than the Cu.  Alternatively, before sintering, the powder may be spread on a steel backing strip having a thin electroplated metal as its surface.  The sintered metal may be used for piston pin bushings, cam shaft bushings, balancer shaft bushings and thrust washers.

In a die-head intended for use with a blowmoulding machine, the supply pipe 2 (fig., not shown) contains means for forcing material along the pipe and one or more " storage pots " 3, 4 for collecting material forced along the pipe, communicating downstream of said means. Each pot has a piston 8 for forcing material out into and along the supply pipe, constructed such that, at the end of its material ejection stroke, the crown of the piston (10) is flush with the inner surface of the supply pipe so that material forced along the pipe by said means or from another storage pot further upstream, is forced past this piston crown. The pot may be cylindrical, communicating directly with a straight run of the supply pipe so that the longitudinal axis of the cylinder diverges from that of the supply pipe in the direction opposite to the material flow direction, the piston being mounted non-rotatably. There may be one or more storage pots communicating with the supply pipes at different places, and they may be disposed on either side of a straight run of the pipe. Each piston may be connected to a hydraulically-operated prime mover (9).

Title: Improvements in or relating to rayon filaments and method of producing the same
IPC: D01F2/06
Filed: 1945-12-07
Abstract: Rayon filaments having a high resistance to fatigue on repeated bending are obtained by extruding viscose of normal spinning viscosity, but containing less than 6.5 per cent of combined cellulose through spinning orifices of not more than 0.0025 inches diameter into an acid coagulating bath containing not less than 2.5 per cent of zinc sulphate.  The viscosity of the viscose may be about 45 or 46 poises, or 30 seconds by the standard 1/8 inch falling ball method.  In an example, viscose is prepared so that it contains 4.5 per cent of cellulose and 6.5 per cent of caustic soda.  Prior to the xanthation, the alkali cellulose is aged for a shorter period than normal, e.g. 11 hours at 20 DEG  C. The viscose is ripened for 48 hours at 19 DEG  C. and is spun into a setting bath containing 8-9 per cent of sulphuric acid and 4 per cent of zinc sulphate.  The yarn emerging from the spinning bath is stretched in a hot water bath.  In other examples, viscoses of 4 to 6.5 per cent cellulose content are employed.  The viscose may be obtained from wood pulp or cotton linters.  The yarn obtained may be used in the preparation of tyre cords or textile fabrics. Reference is made to the production of staple fibre, artificial straw and artificial horse-hair.

Title: Coatings for niobium and niobium base alloys
IPC: C23C26/00
Filed: 1964-08-17
Abstract: Niobium or niobium base alloys, e.g. Nb-20 Ta15W-5Mo, are coated with a CoAl compound.  The coating may include impurities up to 20% by weight of e.g. Fe or W.  It may be applied by flame or plasma torch spraying, as a slurry, hot pressure bonding, electrophoretic deposition or a pack cementation process.  In an example of electrolytic deposition, an iron strike is formed using an iron formate bath, then a layer of cobalt is formed from a cobalt sulphate and chloride bath, followed by a flash plate in a fused bath of AlCl3 and NaCl, and Al is subsequently deposited using an ether hydride aluminium plating bath.  The whole is then heated in argon.  A cementation example, niobium or a niobium alloy substrate is cobaltized in a pack (in a steel or graphite container) comprising (per cent by weight) 10 to 40 cobalt, 2 to 12 ammonium chloride, and an inert filler, e.g. Al2O3.  The pack is heated in an argon atmosphere at 1400 to 2200 DEG F. The substrate is then embedded in a pack containing 1/2 to 15 aluminium powder or flake, 0.05 to 3 powdered halide salt, and an inert filler, e.g. Al2O3. The pack is then heated in an argon atmosphere at a temperature of 1600 to 2200 DEG F.  Alternatively the aluminizing step may be effected without the halide salt.
