Abstract: A degreasing apparatus comprises a vessel (3) the lower portion of which is shut off by means of a bowl-shaped plate (5), to form a container (1) with a heating means (2) for boiling solvent. The bowl-shaped plate (5) has an opening (6) at its lowest point. A valve means (7) is arranged at the opening (6). The valve means (7) comprises a body, preferably a ball, which can seal against a seat which surrounds the opening (6). The density and size of the body are related to the size of the opening (6) so that the body floats up from the seat in the presence of solvent condensate, so that condensate can pass from the valve means to the container (1). Vapor pressurized in the container (1) by the heating means (2) lifts the body from the seat so that vapor can flow up into the treatment space of the vessel (3). When the apparatus is shut off, the body seals the opening (6) and thereby prevents evaporation of solvent from the container (1).

Abstract: Waste thermoplastic resin film is cleaned to reclaim raw material for subsequent recycling by crushing a mass of the waste film into pieces and then feeding the pieces onto a moving mesh conveyor immersed in a wash tank which is filled with a cleaning liquid; the liquid being at a temperature sufficient to soften the pieces. Cleaning is promoted by irradiating the pieces on the conveyor with ultrasonic energy from positions located on opposite lateral sides of and just above the upper surface of the conveyor while simultaneously forcing liquid in the tank to flow in the same direction as the conveyor while directing jets of additional liquid into the tank in the opposite direction to produce a forced circulatory flow pattern within the tank.

Abstract: High pressure parts washer having a hand directed spray nozzle, and an enclosing chamber containing the parts in a manner whereby the spraying zone for solvent, with which the parts are sprayed by the nozzle, is closely confined within the enclosure so as not to expose the operator or the outside environment to the liquid runoff of the solvent, or to the sprayed particles thereof, or to solvent steam or rising vapors. With a view to ecology considerations, and in addition to the concern to confine the contaminant from escaping into the environment, the internal atmosphere of the chamber and all solvent are continually recycled for re-use by the washer.
