Abstract: A system for vertically lifting and lowering a container relative to a supporting surface. The system includes at least two lift mechanisms wherein each mechanism includes a frame attached to the container. An elongated cylinder and piston is associated with each frame so that its axis is substantially vertical. A control circuit selectively connects a power source to each cylinder and piston to move the cylinder and piston between a retracted position in which the piston is spaced upwardly from the supporting surface and an extended position in which a foot on the piston engages the supporting surface and lifts the container upwardly from the supporting surface.

Abstract: A glovebox air intake emergency safety shutoff system includes a glovebox; a first manual valve operatively connected to the glovebox, wherein the first manual valve articulates between an open position and a closed position; an automatic valve operatively connected to the manual valve, wherein the automatic valve articulates between an open position and a closed position; an air intake component that inputs air into the glovebox; an air exhaust component that discharges air from the glovebox; and a pressure monitor that detects a level of pressure in the glovebox. The pressure monitor includes a pressure sensor that measures a pressure in the glovebox and transmits a signal associated with the measured pressure; and a pressure controller that receives the signal and responds according to the measured pressure. The pressure controller operatively closes the automatic valve upon the measured pressure increasing above a predetermined limit.

Abstract: A system and method to safely dispose of hazardous liquid waste includes a glove box for conducting a test with a hazardous liquid material therein, the glove box having a drainage line connected to a waste tank for directing the hazardous liquid waste from the glove box to the waste tank. A waste disposal line and an air vent line are connected between the waste tank and a waste container. Double-valved connectors are positioned in the waste disposal line and in the air vent line allowing the liquid waste and air to flow between the waste tank and a waste container when the double-valved connectors are coupled together. When the double-valved connectors are uncoupled, both the waste tank and the waste container are completely sealed to the surrounding environment.
