Abstract: A linear translation device includes a frame, a carriage pivotally coupled to the frame, a drive arm body coupled to the carriage and rotatably coupled to the frame, and an actuator coupled to the drive arm body and the frame to effect rotation of the drive arm body about a pivot point. The device effects linear motion to the carriage by rotating the drive arm body by the actuator about the pivot point. An object, such as an optical component, is secured to the carriage such that linear motion of the carriage conveys linear motion to the object. Each of the frame, carriage and drive arm body are preferably coupled to each other with flexures to facilitate substantially frictionless linear translation of motion to the carriage and object secured to the carriage when the drive arm body is rotated by the actuator.

Abstract: A method and apparatus for regenerating contaminated or spent water-glycol fluid used as a fire resistant hydraulic fluid. The spent fluid is delivered to a process tank and allowed to settle so that oil floats to the surface and can be skimmed off and removed. Water can be deionized and added to the process tank if necessary. The fluid is pumped out of the process tank and passed through progressively smaller particulate filters and then through a filter media bed for removal of oils, grease, hydrocarbons, dissolved hydrocarbons, hydrolyzed acids, solvents and organic compounds. The purified fluid is delivered to a finish tank to which metered amounts of specified additives can be supplied.
