Abstract: An oil and waste line connection spillage containment apparatus, constructed from non-corrosive and rustproof materials, includes a substantially cylindrical container which has two openings for receiving oil and waste loading and unloading lines therein. The lines are connected within the container. A circular cover encloses the container and is quickly and securely fastened and unfastened from the container using a pair of L-shaped members which extend from the cover and cooperatively couple with a lip defined around the top of the container. Any oil and waste spilled from the connection is removed from the container when the lines are disconnected, or alternatively, a removal line with an auxiliary valve affixed thereto, is used to siphon the oil and waste from the container to the loading line. When the unloading line is removed from the opening in the container, a plug having vent holes for releasing gas from the container, is inserted into the opening.

Abstract: A low temperature purification system is provided which is particularly adapted for use to mechanically purify in a continuous operation solutions containing solids and dissolved substances. The purification system includes a solution supply means, and a centrifugal vacuum evaporator to which the solution to be purified is fed. Drive means is operatively connected to the evaporator for subjecting the solution within the evaporator to centrifugal acceleration and causes the solids in the solution to be displaced outwardly of the axis of rotation of the solution and the liquid of the solution to be displaced inwardly toward the axis of rotation. Outlet means is embodied in the evaporator for discharging the solids therefrom. The liquid as it is being displaced inwardly is simultaneously subjected to a reduced pressure to produce vapor which is conducted to a condenser means wherein the vapor is condensed to a substantially pure liquid.
