Abstract: An apparatus and method for applying a liquid dressing to a bowling lane has a chassis with wheels to guide the chassis along the longitudinal length of the lane. A spray nozzle for spraying the liquid dressing onto the bowing lane is mounted to reciprocation on the chassis and in a transverse direction parallel to the transverse width of the bowling lane. A metering valve meters liquid dressing to the spray nozzle as the spray nozzle moves in the transverse direction and at controlled velocity for applying the dressing in a selected profile across the transverse width of the lane.

Abstract: A purge concentrate for purging paint spraying and other coating equipment has about 20%-60% by weight water; about 10%-40% by weight of an active solvent; about 10%-50% by weight of a co-solvent; about 1-9% by weight of a penetrant; and about 0.2-2.0% by weight wetting agent. It need not be heated to the curing temperature of heat curing paints and thus purges these paints more effectively.

Abstract: An apparatus, method and purge concentrate are capable of purging water-based and non-water-based paints and other coatings from automated and manual equipment using non-VOC containing aqueous purge solutions. Purge solutions of the invention contain water, detergent builder and wetting agents. The solution is maintained at a selected concentration and at a selected elevated temperature range by continuously recirculating the solution through the automated coating equipment. For manual equipment the solution is set at the correct concentration and maintained at the correct temperature range. For an automated system, spent purge solution can be reconditioned and recirculated to avoid waste.

Abstract: A retrofit manifold, system and process for converting a solvent vapor degreaser to an aqueous solution degreaser is provided for an efficient and environmentally safe method for removing contaminants from workpieces, manufactured articles and other parts. A uniquely designed agitation manifold is fitted at the back wall of the wash tank. Unclean workpieces are submerged in hot aqueous solution in the wash tank and are positioned in the wash tank in front of the agitation manifold. A plurality of nozzles arranged at each section of the manifold spray aqueous solution at the workpieces. Oil based contaminants separated from the workpieces are collected at the surface of the aqueous solution and exited from the tank along with a quantity of aqueous solution. The contaminants are removed from the system and the aqueous solution is recycled back into the wash tank.
