Abstract: An information distribution system, in accordance with one form of the present invention, includes a central information bank and a central transactional data base coupled to point-of-sale delivery systems. Information flows between each point-of-sale delivery system and the central information bank and central transactional data base via a communication network such as the telephone network, a satellite network, or any other network suitable for the transfer of information. The point-of-sale delivery systems may take one of many forms including a point of purchase delivery system, a point of rental delivery system, a “book bank” subsystem, a promotional delivery system, or any combination of such systems.

Abstract: Metal cleaning formulation for the preparation of low temperature-low foam aqueous metal cleaning and polishing baths. The formulation includes an alkaline builder consisting of sodium metasilicate together with sodium hydroxide, sodium carbonate, or mixtures thereof. The system includes sodium gluconate, the tetrasodium salt of ethylenediaminetetraacetic acid, kerosine, and a biodegradable wetting agent system. The wetting agent system utilizes a mixture of linear primary alcohol polyethers and a linear alcohol alkoxylate, with the linear primary alcohol polyethers having cloud points of about 40.degree. C. and 26.degree. C. respectively, and with the linear alcohol alkoxylate having a cloud point of about 20.degree. C. The formulation is free of either poly or orthophosphates.

Abstract: An acidic wood finish remover formulation which consists essentially of a mixture of hydroxyacetic acid in methylene chloride solution. A vapor pressure depressant is present, such as paraffin and a solubilizer for the wax, such as toluene is present. An anionic detergent consisting essentially of linear alkyl benzene sulfonic acid is utilized as well as a corrosion inhibiter for permitting retention of the material in metal storage vessels.

Abstract: A formulation for the surface treatment of metal articles wherein the article to be treated is immersed and agitated in a working solution of the formulation. The formulation consists essentially of the esterification reaction product of phosphoric acid based upon P.sub.2 O.sub.5 with an alkylphenol of either octylphenoxypoly (ethyleneoxy) ethanol or nonylphenoxypoly (ethyleneoxy) ethanol, and wherein the mol ratio of the reactants ranges from between about 1:3 up to about 3:4 of P.sub.2 O.sub.5 to alkylphenol.
