Abstract: Fluorinated terpenes useful in a wide variety of general cleaning and degreasing applications are disclosed. These compounds have high solvencies but reduced flash points, and include derivatives of paracymene and myrcene, both of which, while relatively unreactive, are nonetheless miscible with a wide variety of hydrocarbon soils. The compounds exhibit flash points of 25.degree. F. or more above those of the unmodified terpenes.

Abstract: A pneumatic cleaning and degreasing system that draws power from a single source of compressed air and provides agitation, active draining of solvent, drying, odor-control and optional recirculation features. The preferred configuration of the invention provides for the use of two solvents, each in a separate chamber. Agitation, drainage and, if desired, solvent recirculation are accomplished by means of a pair of pneumatic pumps. An air venturi withdraws solvent vapors from the plenum into which the solvent chambers open, thereby creating a vapor gradient that facilitates rapid drying. When the device is inactive, a smaller flow through the air venturi removes solvent fumes to reduce or eliminate perceptible odors.

Abstract: A distillation device for separating a liquid mixture from contaminants contained therein. The device partially cools, using an air radiator or equivalent passive heat-exchange device, a fluid of that contains at least one component of the mixture to be separated; the temperature of the fluid does not fall the ambient air temperature, thus preventing condensation on the heat exchanger. The partially cooled fluid is introduced into an aspirator and combined therein with a gaseous stream produced by heating the mixture to boiling in a separate chamber. Because of the high surface area of contact between vapor and aspirated liquid, the heat transfer is completely effective to condense the gaseous mixture, which settles into a pool. The components can then be separated mechanically or by gravity.
