Abstract: A method and apparatus for the coating of a substrate such as a polyethylene terephthalate container with a gas barrier coating of a copolymer of vinylidene chloride is disclosed. The method includes locating the container to be coated in close proximity to one or more airless spray nozzles and impacting the outside surface of the container with a stream of a stabilized aqueous polymer dispersion such as an aqueous polyvinylidene chloride dispersion. The impacting force of the stable polyvinylidene chloride dispersion on the surface of the container is sufficient to cause selective destabilization of the dispersion at the surface interface to form a gel layer containing the polymer in the continuous phase. This gel layer serves as an adhesive layer for an overlying layer of the aqueous polymer dispersion as a continuous uniform coating. The resulting wet coating does not sag or run off. The coating on the container is then dried in a controlled atmosphere to complete the gel formation throughout its thickness whereupon it is further dried to remove the water from the coating and to collapse the get to form a film without distorting the container. The dried coating is smooth, uniform and uniformly transparent. In operation, the overspray can be collected and returned to achieve greater than 95% material efficiency.

Abstract: A high pressure fluid system for providing fluid to a hand held nozzle, comprising an improved power assisted dump valve which may be remotely located and controlled. The dump valve includes a stepped piston positioned in a stepped bore with one end of the piston adapted for sealing off a pressure relief outlet. A fluid conduit, preferably a passageway through the piston, conducts high pressure fluid to the valve chamber atthe large diameter end of the piston. A control valve either seals off the large diameter end of the chamber or vents it to ambient pressure so that differential pressure supplied by the working fluid itself drives the valve piston to its open or closed positions. An electrical, hydraulic, or mechanical actuator operates the control valve, remotely if desired, to control the flow of high pressure fluid to the nozzle.

Abstract: A hydraulic press flow viscometer is provided for spray testing viscous materials for high pressure applications using a relatively small sample size. A hydraulic press forces the sample from its container to a spray assembly. The spray testing system is capable of accurately simulating robotic applications in assembly plants by controlling material temperature, material pressure and robot speed. A method is also provided for performing high pressure spray tests on material samples using the hydraulic spray testing system.

Abstract: A pump spray dispenser with an inner cylindrical tube (2) in the container portion (1) and a piston mounted on the handle (6) is provided with inwardly directed projections (14) about the mouth of the cylindrical tube. During the assembly process, the container parts with tubular cylinders are slipped onto upright mandrels fixed to a conveyor belt of the like. Each mandrel bends the projections towards the interior end or the cylindrical tube and when the container portion is removed from the mandrel, the projections begin recovery towards their original shapes sufficiently slowly to enable the piston to be inserted past the projections without damaging the piston. The projections then return to a still bent position in contact with the piston stem (4) to center and retain the piston assembly.
