Filed: 1950-12-12
Abstract: 684,726. Cathode materials and processing. SYLVANIA ELECTRIC PRODUCTS. Inc. Dec. 12, 1950, No. 30366/50. Class 39(i) A support is coated with a compound of an alkali metal or an alkaline earth metal suspended in a solution of ethyl cellulose, and the compound, or a derivative thereof, is vaporised to form a monatomic layer on the secondaryelectron-emitting electrode. A carbonate, fluoride or chloride of the metal in a suspension of a solution of ethyl cellulose in amyl acetate may be deposited on the support by spraying, cataphoresis or electrophoresis. Silver compounds, e.g. silver oxide, may be added to increase secondary emission. Proportions are specified. The sprayed coating is stable in air and may be hardened by baking at 400-500‹C. The tube may be degassed and the support bombarded to vaporise the compound on to the electrode; during ageing, parts carrying deposits of emitting oxide are heated to drive the material on to the electrode. In another form, the support consisting of a nickel sleeve is heated to drive a coating of caesium oxide on to an adjacent tungsten filamentary electrode held at yellow heat. The electrode may comprise rhodium, platinum, gold, silver or copper, or, when the electrode is to operate at high temperature, of aluminium or an alloy of nickel, iron and chromium. A tube comprises a filament 10, mounted on a mica disc 11, a mesh grid 14 on a support 16, a secondary-emitting electrode 18 having a barrier coating of metal, and a getter the back of which forms the support for the compound. The tube is baked at 400‹C and the getter flashed whilst the filament is kept at red heat and the grid at 60 volts positive so that a mixture of silver oxide and caesium oxide is vaporised. Subsequent electron bombardment of the grid will vaporise deposited material on to the dynode 13.

Title: Process and composition for dyeing cellulose acetate
Inventor: GALATIOTO LUIGI CARLO
IPC: D06P1/92
Filed: 1946-10-14
Abstract: Cellulose acetate is dyed in a solution of an acid dyestuff in an aqueous lower aliphatic alcohol containing more than 50 per cent of water and also an inorganic or organic acid or both.  The solution may also contain a non-acidic organic solvent, and its composition is such that it lies between the "threshold" value at which it exhibits a wetting and penetrating capacity towards cellulose acetate which is markedly greater than that of the water and alcohol alone and the "critical" point at which the solution exhibits a tendency to cause the acetate to undergo marked increase of absorption and to swell. Examples are given of dyebaths for cellulose acetate containing (1) Wool Fast Blue GL dissolved in 620 c.c. of water to which is added 200 c.c. ethyl alcohol, 60 c.c. sulphuric acid (20 DEG  B<\>a), 60 c.c. formic acid and 60 c.c. acetic acid; (2) Wool Fast Blue GL dissolved in 520 c.c. water to which are added 200 c.c. ethyl alcohol, 60 c.c. ethyl acetate, 40 c.c. sulphuric acid (20 DEG B<\>a), 40 c.c. formic acid and 40 c.c. acetic acid; and (3) Wool Fast Blue GL dissolved in 520 c.c. of water to which are added 400 c.c. ethyl alcohol and 80 c.c. sulphuric acid (20 DEG  B<\>a). Isopropyl and tertiary butyl alcohols may be used instead of ethyl alcohol.  Tables are given showing the results obtained when dyeing from a dyebath containing 20 and 40 per cent of ethyl alcohol and also various amounts of sulphuric acid, formic acid, acetic acid, "Cellosolve" (Registered Trade Mark), carbitol acetate and ethyl acetate. Specification 559,991 is referred to.  The Specification as open to inspection under Sect. 91 is not limited to the use of dyebaths containing more than 50 per cent of water and includes Tables showing the effects of dyeing cellulose acetate from solution of Wool Fast Blue GL in aqueous alcohol solutions containing 60 and 80 per cent of ethyl alcohol in addition to various proportions of sulphuric, formic and acetic acids, "Cellosolve," carbitol acetate and ethyl acetate, and also includes Drawings (not shown) which are graphs based on the information contained in the Tables.

Title: Method of producing thick and lustrous pale yellow gold alloy deposits
IPC: C25D5/48
Filed: 1957-10-01
Abstract: A method of producing gold alloy deposits of a pale yellow colour consists in electro-depositing a thick and adherent gold-copper alloy plating on a metal base and thereafter causing a whitening metal to penetrate by thermal diffusion into the said gold-copper alloy plating.  Whitening metals are silver, zinc, cadmium, caesium, rubidium and selenium.  Thermal diffusion of the white metal into the gold-copper alloy may be effected by the following methods:-(i) plunging the alloy plating into a melt of the white metal, removing it therefrom, and then heating under pressure, (ii) covering the alloy plating electrolytically with a thin coating of white metal and then heating under pressure, (iii) spraying liquid particles of white metal on to the alloy plating in a vacuum and then heating under pressure, (iv) exposing the alloy plating under reduced pressure to the vapour of the white metal by holding it over a vessel containing molten white metal, (v) placing the alloy plated articles in a drum in contact with powdered white metal and subjecting to heat and rotation.  Examples disclose the treatment of an article, coated with gold-copper alloy, by dipping in molten cadmium; electrodepositing a thin layer of zinc; and heating with zinc or selenium powder.
