Abstract: An immersion bath composition and a method for applying a heavy, non-powdery coating of iron phosphate on a ferrous substance which is characterized by the addition of an effective amount of gluconic acid to a solution containing phosphoric acid, a soda ash, a chlorate or organic accelerator and water. Using conventional phosphating bath parameters, immersion of a ferrous substrate into the bath produces a heavy, strongly adherent, iron phosphate coating which is non-powdery or dust free and highly satisfactory for paint pre-treatment of the substrate surface.

Abstract: A hydraulic sensor and pressure transducing apparatus is disclosed which is characterized by the use of a biased piston and valve element arrangement to translate the displacement of an actuator to provide a pressure signal proportional to the displacement being sensed. The piston is mounted in a bore provided with inlet and outlet ports. A valve element is positioned in the bore in an opposing resiliently biased relationship to the piston in communication between the inlet and outlet ports. A constant selected hydraulic flow is fed into the bore inlet through the valve element and out of the bore outlet port to develop a pressure on the inlet port side which is proportionally to the displacement of the piston as reflected by the biased force exerted against the valve element. An actuator is linked to the piston by a cam surface in a manner that permits the angular position of the cam operating on the piston to be reflected as a proportional pressure on the inlet side of the valve element.

Abstract: A coating composition and method of applying the coating to metal surfaces to improve corrosion resistance and substantially reduce coated parts from sticking to one another during the curing step is disclosed wherein a temporary dispersion of a di-phase mixture containing a resin film forming component and a soap film forming component are applied in a single coating step to a metal part. Upon curing the coated part, two distinct layers are formed wherein the resin film is adhered to the surface of the part and the soap film forming component is deposited uniformly over the resin film. During the curing step, the carrier agent portion of the soap film forming component is essentially volatized leaving only an upper layer of a soap film. The soap film is dry to the touch and forms an additional corrosion resistant barrier in cooperation with the underlying resin film.
