Abstract: 860,165. Photographic methods and apparatus. INTERNATIONAL POLAROID CORPORATION. June 21, 1957 [Nov. 28, 1956], No. 19570/57. Classes 98(1) and 98(2) Two photographic prints are produced by the silver halide transfer reversal process using emulsions of the same ASA rated speed but exposures of different magnitude and are processed with different compositions so as ASA equivalent overall speeds appropriate for the different exposures. Thus the exposures may be made with little or no adjustment of diaphragm or shutter setting and processing compositions selected to produce the prints independently of these factors but in accordance with the luminance of the subjects. Seven such compositions are detailed using metol-hydroquinone for exposures corresponding to 25 to 50 reciprocal metre seconds, changing to amidolhydroquinone and then amidol alone for increasing reciprocal metre seconds, together with varying proportions of hypo but constant proportions of sodium sulphite hydrate and carboxymethyl cellulose. Cameras and rupturable containers for the compositions which may be inserted into the cameras after exposure are described and illustrated, thus in Fig. 1 an assemblage 28 having sheels 30, 32 for emulsion and image reception respectively are inserted through gap 48 to take positions in exposure and storage chambers 40, 38 of the camera, and container 50 with the selected composition is endwise inserted into chamber 44 between the sheets after exposure; withdrawal of the assemblage 28 by end portions at the lower left of the figure then causes rupture of the container and spreading of its composition therebetween to effect the processing, the sheets having opaque backs to prevent unwanted light action. Of other Figures, not shown, Fig. 5 is like Fig.1 but has provision for eight of the assemblages, Fig. 6 is for a simple roll film camera and Fig. 7 a roll film camera including a light-sealed imbibition chamber to accommodate the assemblage during processing; and other Figures are concerned with the matters of insertion and operation of the container within the camera.

Patent GB-827705-A (GB)
Title: A process for the preparation of platinum-containing catalysts
IPC: B01J37/20
Filed: 1958-06-23
Abstract: Platinum-aluminum catalysts are prepared by peptizing a hydrogel (entirely or mainly hydrated alumina) by acidifying it to a pH of 5.5-7 (preferably approximately 6) with a dilute aqueous solution of one or more hydrohalic acids (preferably HCl) and/or nitric acid, mixing the peptized hydrogel with a platinum-containing solution, treating with H2S to form platinum sulphide, and drying and calcining the resultant mixture. Preferably before the drying, the mixture is freed from excess water, shaped and pre-dried at 10-40 DEG  C., particularly for 6-24 hours.  Preferably the initial hydrogel contains hydrated SiO2 in such quantity that 0.1-1 part by weight Si (calculated as SiO2) is present to 100 parts Al (calculated as Al2O3), the hydrated SiO2 being distributed uniformly over the hydrated Al2O3; usually, the silica is introduced by emulsifying or suspending in an aqueous Al halide solution one or more organic Si compounds, insoluble or slightly water-soluble, but hydrolysed by water, and by treating the mixture after hydrolysis of the Si compound(s) with aqueous ammonia to precipitate the hydrogel, it being preferable thereby for the mixture to acquire almost immediately a pH of 7.5-8.5.  Suitable organic silicon compounds are alkyl and aryl (a) orthosilicates (e.g. ethyl or phenyl) and (b) metasilicates.  The example describes two catalysts of the present invention: (a) the hydrogel is peptized with HCl solution and the catalyst treated according to Specification 826,448, after which it contained 0.5% SiO2; 0.7% Pt and 0.8% Cl; (b) the hydrogel is peptized with HNO3 solution and the finished catalyst contained 0.5% SiO2, 0.7% Pt and 0.7% Cl, all percentages being based on weight of Al2O3. Specification 782,787 also is referred to.
