Abstract: A washer for utensils, such as baking pans and trays, having a spray chamber containing a movably mounted utensil rack and spray nozzles arranged to impinge upon articles stacked in the rack; a source for supplying wash and rinse water under pressure to the spray nozzles, and a water motor for moving the rack relative to the spray nozzles, the water motor comprising a waterwheel rotatably journaled in a housing, the waterwheel having a plurality of radially extending blades driven by additional spray nozzles mounted on the housing and positioned to direct jets of water onto the blades adjacent their outer ends, the additional spray nozzles for driving the waterwheel being connected to the source supplying wash and rinse water to the spray nozzles utilized to spray the articles being cleaned, the waterwheel mounting drive mechanism for moving the rack relative to the spray chamber so as to obtain complete and efficient washing of all surface of the articles being cleaned.

Abstract: A scarfing torch adapted for manual manipulation which includes means disposed in said torch to provide a component of force upon the torch to offset forces upon the torch generated either by the flow of oxygen gas used in the scarfing process or gravity. The offsetting force is provided by the release of a secondary fluid from the torch in the appropriate direction. The secondary fluid may be released to impinge upon the surface of the workpiece being scarfed.

Abstract: A white rust inhibited composition is comprised of a zinc containing substrate. A white rust inhibiting composition contacts the substrate and is comprised of a vapor corrosion inhibitor and a pH adjusting compound to adjust and maintain the pH of the white rust inhibiting composition between 8 and 12.5.

Abstract: An amine salt is comprised of the reaction of pelargonic acid and dicyclohexylamine. The amine salt, dicyclohexylammonium pelargonate, is useful for inhibiting metal corrosion. A polyphosphate may be used in conjunction with the amine salt to obtain a synergistic corrosion inhibiting effect when a saline environment is encountered by the metal to be protected.
