Abstract: A high impact barrier for the exterior components of an automobile body to enable lightweight automobiles to better withstand collisions and provide a protective enclosure of the passenger compartment, accomplished by bonding precut sheets of heavy gauge SUNPRENE.TM. polyprene onto the outer surfaces of the body panels. Clear sheets of polyprene are also bonded to the interior and exterior windshield and rear glass surfaces, and to the outer surfaces of bumpers and headlight lenses.

Abstract: The present invention provides a chemical solution and method which, when introduced into the cooling system of a liquid cooled engine, removes oxidized material such as sludge and rust by chemical reduction without draining or flushing the cooling system. The solution comprises a liquid carrier, such as water, which is miscible with the liquid of the cooling system, phosphoric acid and zinc oxide. The carrier constitutes about 70 percent by weight of the chemical solution, the phosphoric acid constitutes about 26-27 percent by weight of the solution and the zinc oxide constitutes about 3-4 percent by weight of the solution.

Abstract: A "system" of aqueous liquid cleaning compositions is described wherein the concentrations of each of five basic ingredients -- urea, glycerine, triethanolamine, an organic anionic detergent, and an organic non-ionic detergent -- are defined in terms of the concentration of alkali metal silicate. Within the system three preferred embodiments are used, by way of example, as a hair shampoo, a spot remover, and a laundry detergent, respectively.
