Title: Improvements in or relating to copper/silicate catalyst regenerating process
IPC: B01J23/94
Filed: 1956-10-02
Abstract: A copper sodium silicate catalyst, e.g. the catalyst of Specification 758,731 which consists of reduced copper promoted by a small amount of sodium silicate, is freed from carbonaceous residue by passing a hot gas of oxygen content less than 1 1/2 volume per cent, e.g. superheated steam and air, over it at a temperature above 212 DEG  F. but below the sintering temperature of copper (about 700 DEG  F.) until the copper is substantially completely oxidized.  The temperature may be increased in steps up to the maximum, and is then raised above the sintering temperature until all the carbonaceous residue is removed.  The catalyst is then activated by hydrogenating and used to hydrogenate furfural.

Abstract: 1,058,821. Cooking and drying foods. H. GRIFFON. July 29, 1963 [July 30, 1962; Jan. 28, 1963], No. 30006/63. Heading A2D. [Also in Division B8] In a process for the dehydration of substances of vegetable or animal origin, particularly starchy vegetables such as potatoes and chicken meat, before the dehydration the substance to be dehydrated is conveyed in a continuous flow through apparatus wherein it is first cooked in a heated bath, plunged into a cold bath to cause rapid cooling and finally reduced to a purÚe or pulp. Under preferred conditions of operation, before cooking the substance is divided under water into small pieces, e.g. cubes having a side of about 1 to 2 cm., during the reducing step the cooked substance has added to it after the cooling between one-third and one-half its weight of water or milk and the resulting mixture is beaten into an emulsion by the occlusion of air, and the emulsion is dried, as a thin layer upon a moving endless band, in a current of warm air of which the temperature is such that the substance being dehydrated is not heated above 37‹C. The conveyer which transports the vegetable or animal substances through baths of hot and cold water, is made of a plastics material resistant to the maximum temperature involved or of metal, and preferably consists of a grid 10 formed of stainless steel wires 2 mm. in diameter, of which certain of the weft wires are bent up to form the sides 24. Depending from the conveyer, members 13 provide bearings for axles 15 on which are mounted rollers 16 guided by rails 17 and 19.

Title: Photo-lithographic printing
IPC: G03F7/06
Filed: 1960-12-21
Abstract: 979, 577. Photolithographic printing. KODAK Ltd. Dec. 21, 1960 [Dec. 21, 1959], No. 30229/64. Divided out of 978,744. Headings G2C and G2M. A method of photolithographic printing comprises the steps of exposing a silver halide emulsion layer to a subject; developing the exposed layer, while in contact with a reception layer of a tannable hydrophilic organic colloid containing a silver-precipitating agent, with a solution containing a developing agent capable of oxidation in the presence of a tannable hydrophilic organic colloid to form an oleophilic image together with a silver halide solvent, whereby the undeveloped silver halide of the exposed layer is transferred to the reception layer and an oleophilic image is formed thereon; inking the image so formed while it is still moist with greasy printing ink, and printing therefrom. The reception layer may be coated on a separate support or coated on the surface of the silver halide emulsion layer. As described a film support was coated with a gelatino-silver chlorobromide emulsion containing mucochloric acid, and this layer was overcoated with a dispersion of zinc sulphide in gelatin containing mucochloric acid. After exposure development was effected with a solution containing 4-phenyl catechol, sodium thiosulphate, sodium carbonate and sodium hydroxide. Thereafter the film was rinsed in dilute acetic acid, inked, treated with dilute phosphoric acid fountain solution and ink printer made. Other developing agents referred to as suitable are chloro- or bromo-hydroquinone, pyrogallol or its formic or acetic acid esters, 4-n-butylpyrogallol, 4-tert-butylcatechol, 4:5-dibromocatechol, 3:5:6-tribromo-4-phenylcatechol, nordihydroguaiaretic acid, 1-phenyl-3-(N-n-hexylcarboxamide)-4-[(#-hydroquinoylethyl)-phenylazo]- 5- pyrazolone, and pyrogallol together with a non- tanning developer such as metol or a 3-pyrazolidone. In place of gelatin the hydrophilic organic colloid may be soy bean protein, casein, polyvinyl alcohol, or hydrolysed cellulose esters, and instead of zinc sulphide other silver-precipitating agents or development nucleii as in Specification 868,241 may be used.
