Abstract: Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer and an electrically-conductive layer comprising a film-forming hydrophilic colloid having dispersed therein both electrically-conductive fine particles and pre-crosslinked gelatin particles. The combination of hydrophilic colloid, electrically-conductive fine particles and pre-crosslinked gelatin particles provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.

Abstract: Photographic film, paper, etc. in sheet form is packaged in recyclable containers or cases for reuse by returning to suppliers for filling. Containers obviate disposal problems and high costs associated with customary two-part set-up box and interior padding. Plastic cases comprise a base section in the form of a tray-like structure with an open bed for a film stack, etc. Case has built-in structural features for rigidity, crush resistance, impact protection, and air, dust and light tight seal when used with a cover section. Such environmentally friendly designs are suitable as low cost, reusable one-size plastic containers for packaging standard size sheet products. For packaging special, less frequently called-for size films, papers, etc., interiors may be made infinitely adjustable with rows of parallel channels for placement of at least one chocking element.

Abstract: The method for preparing high grade gelatin with a specific methionine content and with reduced methionine variability from batch to batch and within a single extraction includes controlling the amount of and variability of oxidant present during processing of bone stock into gelatin. Such controls include control of oxidant concentration and range in process water, control of volume of process water used in gelatin-making process and restriction of the range of gelatin extracts used in the product gelatin. Once the aim level of oxidant has been set, the total range of oxidant around the set point should be less than 220 meq per 100 kg dry bone.
