Abstract: There is disclosed a composition of matter useful for stripping paint and varnish from substrates comprised of the conventional industrial chlorinated solvents, e.g. methylene chloride (dichloromethane) solvent and a wax, such as paraffin wax, which composition is improved by the addition thereto of a novel class of evaporation retarding chemicals resulting in a far more effective stripping action and a much improved environmentally desirable composition, with respect to the concentration of methylene chloride in the ambient atmosphere surrounding the work situs. The evaporation retarding chemical can be a surfactant, a resin plasticizer or ethylene or propylene carbonate.

Abstract: There is described a device and process for delivering a predetermined quantity of molten metal to a metal casting operation via metal transfer members, such as thermally heated pipes under a positive head to the shot size and delivery system wherein the device has a metal receiving chamber, a hydraulic ram for metal movement and an inert gas sweep capability. The ram chambers has only a nominal relationship to the volume of metal to be used to fill the mold, the true measurement of the volume being a factor of the pressure of the molten metal being delivered to the chamber and the time the molten metal is allowed to flow into the chamber before the ram is activated to force the metal under a definite predetermined pressure into the mold cavity.

Abstract: There is disclosed a procedure for removing copper inhibitor from a circulating fluid which contains the same, which copper may be lost on the cool side of a gas conditioning system by plating out under certain conditions, by contacting a portion of the circulating hot fluid with an activated carbon bed to sorb the copper in excess of the solubility limits within said fluid, regenerating said carbon bed when saturated by contacting said carbon bed with cool circulating fluid, thus returning copper which may have plated out to the circulating fluid in an amount and in an ionic state which will not plate out in the system, the circulating fluid is also treated on the cool side by mechanical filtration, activated carbon sorption and/or ion exchange to remove physical and chemical impurities, contaminates and degradation products.

Abstract: A process for enhancing coal by removing the gangue (rock, shale, iron pyrites and the like) associated with the mined coal as it comes from the crushers before further treatment. The process described slurries the crushed run of the mine (ROM) coal with a heavy medium, such as perchloroethylene, for a short period of time at ambient or below temperatures, (i.e. slurry times of 5-30 minutes and temperatures of 90.degree. C. to below -10.degree. C.); thereafter allowing, in a substantially quiescent environment, the solids to settle or float as their inherent densities are greater or lesser respectively than the density of the heavy medium. After settling the float solids (mostly coal of lower sulfur and ash content) are separated from the heavy medium as one stream and the sink solids (mostly the gangue) as a second stream. These solids are each washed with hot (90.degree. C.-100.degree. C.) water and the vapor azeotrope which forms from the water and heavy medium mixture (azeotrope) removed.
