Title: Phosphors
IPC: G21K4/00
Filed: 1974-07-03
Abstract: 1465156 Luminescent materials and uses thereof EASTMAN KODAK CO 3 July 1974 [5 July 1973] 29502/74 Heading C4S [Also in Division H5] A method of making a phosphor of formula (L 1-x A x ) 2 O 3  where L is Y, Gd or La and activator A is one or more of Eu, Tb, Gd and Dy, x being 0À0001 to 0À1 wherein as a first step a salt, or hydroxide, or oxide of the host element and a salt, or hydroxide or oxide of the activator element(s) are heated together in contact with an oxygen-containing atmosphere until the desired mixed metal oxide phosphor is produced, and as a second step the phosphor so made is heated to at least 400‹ C. in contact with a reducing gaseous atmosphere free of halogenating agents, chalcogenating agents and fluxes. Sintering should be avoided. Crystals which are each a mixed salt or hydroxide are preferably salts of an organic acid, e.g. oxalic, citric, acetic, tartaric or carbonic. Preparations are detailed and include references to other parent Specifications, e.g. coprecipation as in British patent Specifications 1,254,271 and 1,161,871. Reducing atmospheres are specified, e.g. hydrogen plus nitrogen or an inert gas, or that produced by a carbon boatwater vapour atmosphere. The two heating steps may be in separate furnaces or a two zone furnace. Examples I to VIII detail coprecipitations for specific phosphors while in Example IX, gadolinium oxide and europium trichloride are mixed in a glass mortar, dried, ground and heated at 1115‹ C., followed by heating in a carbon boat in flowing wet argon and nitrogen or heating. The phosphors may be used in TV c.r.t.s, fluorescent lamps and X-radiographic screens, which latter may be coated on one or both sides with silver halide emulsion (see Division H5). The high speed of the phosphor allows absorbing layers for cross-over control. The high density improves sharpness without excessive mottle. The phosphor in the screen may be dispersed in a binder such as copolymer of acrylic acid and an alkylacrylate, a vinyl chloride polymer, polyvinyl butyral, or polycarbonate resin, on a polyester support film. Phosphor to binder ratio may be 4 : 1 to 30 : 1 and coverage 15 to 120 grm./ft.<SP>2</SP>. A double screen arrangement with halide films and dye or other absorber is detailed.

[Also in Groups XXIV and XXXIV] A metal article comprises a body of sintered metal powder in which is embedded a thin apertured frame, portions of which project. In the manufacture of a bearing liner, a steelapertured frame 1 is embedded in a 60/30 copper-lead alloy powder (obtained by the method of Specification 654,803, [Group II]), and pre-sintered at about 400‹ C. The assembly is then pressed at 100-1000 kgs./cm<SP>2</SP>. in a final mould and sintered at about 750-800‹ C. It may then be pressed again. Locating bushes la project from the frame 1 and lubrication holes 8 are formed initially in the powder. Bearing liners are also made by partly covering a metal cloth frame with the powder. Final sizing may then be carried out by compression between the shaft and the bearing in assembled positions. When sintering a bronze alloy powder, the cloth may have iron warps and copper wefts. Brake or clutch linings may be made in a similar manner. U.S.A. Specification 1,919,168 also is referred to.

Title: Improvements relating to the hydrofining of hydrocarbon oils
IPC: C10G49/00
Filed: 1946-10-10
Abstract: Hydrocarbon oils, particularly those of petroleum origin, are hydrofined by passing them at a space velocity exceeding 1 v./v./hr. over a supported cobalt molybdate catalyst at elevated temperature and pressure together with a gas mixture comprising a minor proportion of hydrogen and a major proportion of diluent gas which does not appreciably impair the activity of the catalyst.  The hydrogen-containing gas mixture may be obtained from the gas mixture formed during the thermal cracking of petroleum hydrocarbons such as naphthas by removal of the unsaturates from the mixture such as hydrogen-containing mixture consisting predominantly of methane.  The preferred catalyst is cobalt molybdate on alumina.  In the examples, gas oil is desulphurised by passing it together with the hydrogen-containing gas over the catalyst and the treated oil passed to a gas separation zone maintained at the reaction pressure, but at a reduced temperature.  In the gas separation zone, the hydrogen and p  light hydrocarbons, principally methane, are liberated.  These may be continuously recycled to the reaction zone if desired after removal of hydrogen sulphide by scrubbing, make-up gas being added of a composition to keep the hydrogen partial pressure substantially constant, or they may be vented to the fuel gas main or otherwise disposed of.
