Abstract: An electrochemiluminescent layer for use in apparatus for determining the concentration levels of pollutants in water by measuring the increase in light emission of a luminescent surface electrochemically excited by a supporting electrode surface, where a tris bipyridyl ruthenium complex forms a homogeneous mixture with a perfluorinated, sulfonated polymer film, deposited on a transparent, electrically conductive surface, in which case the surface may also have a fine-grained structure.

Abstract: An antifouling coating comprising no toxicant. The formulation contains in combination zinc and carbon which in the presence of the aqueous environment render the coating resistant to fouling.

Abstract: A polymeric gelled electrolyte and the method for preparing the novel polymeric elelctrolyte in a crosslinked and noncrosslinked state is disclosed. The polymeric electrolyte is prepared from chitosan which may be crosslinked with aldehydes or remain uncrosslinked and form a superior electrolyte upon gelling in alkaline liquid.

Abstract: A new and improved on-site method for protecting an internal combustion engine in the field for maximizing service time by determining the change point of the lubricating oil. The on-site method utilizes a new colorimetric method and apparatus which serves as an indicator of the amount of acid build-up in the lubrication oil. The apparatus is a test strip formed from a polymeric matrix comprised of ion-rich domains known as an ionomer. A dye is bonded to the ion-rich domains and then activated by dipping the test strip in a basic solution.

Abstract: A system for controlling the flow of thermal flux including a heat source and a heat sink being in proximity to each other and an electrochemically variable thermal switch to control transfer of heat therebetween.

Abstract: A method of treating fluids containing impurities by means of an electrochemical reactor consisting of at least one pair of opposed main electrodes, a power source capable of generating an alternating current connected to the main electrodes, and a plurality of auxiliary electrodes disposed between the main electrodes which are uniformly arranged in a mutually close relationship. The auxiliary electrodes may be disposed on the surfaces of nonconductive supports so as to form a macroporous mixed filler layer between the main electrodes. Control of the electrochemical reactions is achieved through the choice of electrocatalytic materials on the surfaces of the auxiliary electrodes and materials dissolved in the fluid to be treated.

Abstract: Structures to serve as selective magnetic sorbents are formed by dissolving a cellulose derivative such as cellulose triacetate in a solvent containing magnetic particles. The resulting solution is sprayed as a fine mist into a chamber containing a liquid coagulant such as n-hexane in which the cellulose derivative is insoluble but in which the coagulant is soluble or miscible. On contact with the coagulant, the mist forms free-flowing porous magnetic microspheric structures. These structures act as containers for the ion-selective or organic-selective sorption agent of choice. Some sorbtion agents can be incorporated during the manufacture of the structure.

Abstract: Procedures for feeding fish or crustaceans are disclosed which make possible monitoring the extent to which the administered food is actually eaten. These procedures utilize fluorescent dyes which are commingled with the food in order by their release into the culture water to indicate the extent to which the feed is being eaten. By administering food containing fluorescent dyes which when eaten cause the culture water to fluoresce, a direct measure of the food eaten is achieved. By administering food containing fluorescent dyes which when not eaten cause the culture water to fluoresce, a direct measure of the extent of wasteful overfeeding is achieved. By administering food containing both types of fluorescent dyes simultaneously, and measuring the ratio of their fluorescences, a sensitive measure of feeding activity is achieved.

Abstract: A flexible, water activated electrochemical cell and battery suitable generally for application in marine devices requiring low power levels for long periods of time without maintenance or replacement is fabricated in the shape of a rope. This novel shape permits extension of the rope battery cells over long distances and greatly increases the rates at which deleterious reaction products can be liberated to the surrounding water and thus greatly improves the efficiency of low drain water activated batteries.
