Abstract: This invention relates to an improved smoke generator. In particular it relates to a method and apparatus for producing dense smoke clouds for camouflage purposes utilizing a solid propellant.

Abstract: A system for automatically dispensing metered amounts of viscous product in assembly-line fashion into each of a series of containers, wherein the temperature of the product is maintained within a preselected range along its path of flow. Structure is provided for substantially reducing product leakage along the path of flow, including a pneumatically actuated shut-off valve which operates in the nozzle in synchronism with each piston stroke. Structure is also provided for precisely adjusting the individual piston strokes.

Abstract: Enhanced resistance to the corrosion of metals such as aluminum, zinc, magnesium and the like is achieved by the application of a metallo-gel film. The composition of the coating uniquely includes liquid manganese nitrate and sodium tungstate as accelerators which accelerate and activate the chromate sources to coat the metal surface being treated.

Abstract: An apparatus and method for improving the surface characteristics of wax-based material such as a deodorant or anti-perspirant stick housed in a container is provided. The apparatus comprises a hollow walled housing having an inlet and outlet portion. A plurality of rows of horizontally mounted endless conveyors each comprised of a plurality of interconnected conveyor feet are mounted in the housing for moving containers therethrough in reciprocating fashion. A plurality of spaced separators are mounted between the rows and containers move sequentially through these rows from the inlet to the outlet of the housing. A duct system is connected with the housing for circulating air through the housing and creating a reduced pressure therein. A plurality of heating units arranged in sequence are mounted over the rows which units are capable of melting the wax-based material.

Abstract: Separation of liquid mixtures is achieved through a chromatographic method by employing centrifugal force in combination with dielectrophoretic force. The dielectrophoretic force is generated by electrostatically charging a flat rotatable surface. The resulting non-uniform electrical field acts on the liquid that is applied to the surface.
