Abstract: A disposable, centrifugal separator for separating contaminants from contaminated oil is disclosed. The centrifugal separator has a shroud which defines a first chamber and has a hollow rotor rotatably mounted in the first chamber and defining a second chamber. Oil under pressure is admitted to the second chamber through concentrically arranged tubes or spindles and past a low pressure shut-off valve. The oil flows into the first chamber through tangential reaction nozzles in the rotor to cause contaminants to migrate toward the sidewall of the second chamber under the influence of centrifugal force. The shroud and rotor are permanently closed so that the entire assembly may be discarded when a significant amount of contaminants has been deposited on the sidewall of the second chamber.

Abstract: A skiving tool is disclosed for removing a layer of hose or the like to prepare the hose for receipt of a fitting. The tool includes a mandrel which is proportioned to project into the end of a hose to laterally support the hose with respect to the tool while permitting relative rotation between the tool and the hose. The tool includes an adjustable tool post which supports a disc cutter and a chisel-type cutter which cooperate to cut away a layer of the hose as the tool is rotated around the axis of the hose. The adjustment of the cutting depth of the two cutters is accomplished by rotating the tool post with respect to a support arm. A torsion spring is connected between the support arm and tool post to bias the tool posts in one direction and to maintain engagement between the end of an adjusting screw and the surface on the tool post. Adjustment is obtained by loosening a lock nut to allow adjusting rotation of the tool post and then adjusting the screw in or out to the desired position.
