Class 98(2) The water-in-oil type emulsions of Specifications 718, 404 and 750,201 in which a black and white or colour gelatin-substitute emulsion which may contain colour formers forms the dispersed phase in a continuous phase of a water-insoluble waterpermeable cellulose ether are varied bv replacement of the latter by another water-insoluble polymeric material capable of forming a layer which is permeable to photographic processing solutions. The description refers to production of emulsions for colour photography, more particularly for mixed grain layers; but nine specific examples are all concerned with gelatino-silver halide emulsions for black and white procedure, thus in Example 1 a chloride-iodide emulsion for printing paper is added to a chloroform solution of a diethylene glycol terephthalate polymer prepared by heating dimethyl terephthalate with diethylene glycol in presence of zinc acetate to effect ester interchange and polymerizing the product at reduced pressure, the emulsion polymer mixture is stirred and passed through a colloid mill, applied to the paper by a draw knife, imagewise exposed after drying, and developed in metol/hydroquinone and fixed. Example 2 is similar except that a chloroform/ butanol mixture is used as solvent for the polyester and a proportion of ethyl cellulose is included therewith. Examples 3, 4 describe the partial dehydration of a chloride emulsion by ethanol precipitation and addition of the product to a butonal/ chloroform solution of methyl methacrylate/methacrylic acid copolymer. Examples 5-8 describe somewhat similarly addition of chloride emulsions to polyamide solutions, and Example 9 to a nonyl methacrylate/methacrylamide copolymer solution. Numerous other polymers for the purpose are listed, and a test to determine the water-permeability of the polymers is described.

Abstract: 1413092 Charge transfer image pick-up devices WESTERN ELECTRIC CO Inc 4 July 1973 [10 July 1972] 31783/73 Heading H1K In a charge transfer image pickup device including sites in a medium at which mobile charge carriers produced by an image can be integrated and stored, and a plurality of transfer electrodes insulatedly overlying the medium for transferring stored charges to an output, means are provided for establishing a drain adjacent each storage site and for establishing a surface potential between site and drain such that any excess mobile carriers at the site are transferred to the drain rather than to adjacent storage sites. In a typical area imaging device Fig. 1, based on a P-type silicon wafer, having an illuminated image area and a storage and readout area shielded from light the storage sites are located at the intersections of transfer electrodes in groups #1i and #2i and P-type channels 13 defined between potential barriers provided by P+-type finger regions 12. When sufficient charge is stored to raise the site potential to that of the barrier charge flows to an N + drain region 15 held at a fixed potential. Transfer of charges to the storage and readout area and hence to the output is as described in Specification 1,365,751. Alternative ways of providing the barrier are to increase the thickness of the oxide insulation over and adjacent the fingers of the drain region or to provide an additional fixed bias electrode on the insulation there from which the overlying transfer electrodes are insulated. In the line image pick-up device of Fig. 5 excess charges accumulated in the storage sites pass to N+ drain region 20 by overcoming the potential barrier provided by the voltage on electrode 22, which is less than that applied to electrode #2 to transfer stored charge to the readout area, or by a P + region in the same position. The drain may alternatively be constituted by an area underlying a suitably biased electrode and extending to an N+ region. The devices are produced by conventional processing.
