A method for making a collagen strengthened cellulosic sheet by providing a cellulosic pulp slurry; adding solubilized collagen to the pulp slurry, and mixing for a time effective for interaction of the cellulosic pulp slurry and solubilized collagen; forming the interacted cellulosic pulp slurry and solubilized collagen into a sheet; and drying the sheet; also, a method for using solubilized collagen for strengthening paper by mixing the solubilized collagen with a cellulosic pulp slurry; and making a cellulosic pulp product from the mixture and drying.

The overcoat emulsion for protection a carbon spot or other image transfer medium against smudging is made from a polyethylene wax emulsion. In addition, a stilt such as wheat starch may be added to the emulsion to improve the pressure absorbing qualities of the overcoat. In addition, a surfactant may be added to the emulsion to improve the wettability characteristics of the emulsion when being applied to a substrate such as a paper ply of a mailer.

An improved container for the storage, display and protection of collectable items such as graded coins, stamps, jewels and other valuables is disclosed. Display of the collectable items is enhanced by an optical element which provides reflective means for viewing the item indirectly. A reflecting prismatic ring is preferred to provide viewing of the periphery of a cavity or the collectable item enclosed therein. In a second embodiment where two or more components may completely enclose the cavity, various tamper-resistant and tamper-evidencing features are further incorporated in the container design to discourage and prevent fraudulent substitutions of collectable items, modification of grade and value certificates enclosed therewith, or counterfeiting of container components.

Protective coin holder

An improved coin holder for the storage, display and protection of graded coins and other valuables is disclosed. Various tamper-resistant and tamper-evidencing features of the coin holder discourage and prevent fraudulent attempts to obtain access to replace graded coins with those of lesser quality, or tamper with coin grading certificates sealed with the coin in an inner element. Additional features discourage and make difficult the wholesale counterfeiting of the coin holder itself. The coin holder may be partially disassembled to obtain direct, unobstructed access to the coin contained therein, while maintaining the integrity of the grading certificate retained in the inner element along with the coin. The device introduces greater security and certainty into the process of marketing graded and increasingly valuable numismatic items. With minor modifications, the present invention may be used to secure grading small and medium-sized valuables for transport, grading and sale, such as diamonds, jewels, jewelry, stamps, and the like.

There is disclosed the use of microencapsulated antidegradants in rubber and a process for the production of microencapsulated antidegradants. More specifically, this invention is directed to the cellulose acetate microencapsulation of para-phenylene diamine based antiozonants at wall to core ratios greater than 1:1 but less than 4:1. The microcapsules preferably have a particle diameter of less than 50 microns. The microencapsulated antidegradant prepared and used according to this invention provides long term protection to rubber articles that are subject to ozone and oxygen attack.

Processes for the production of antistatic or static dissipative papers. The papers produced may be expeditiously used in dunnage converter machines operable to produce an antistatic (static dissipative) resilient pad-like cushioning dunnage product, for packaging and the like. In one of the processes, liquid antistatic material is applied to a still wet porous paper web produced on a Fourdrinier-type paper making machine, and in predetermined amount for impregnation therein, prior to the completion of the drying of the paper. In another process, a web of dry paper is impregnated with liquid antistatic material, and then the treated web is dried.
