Abstract: In a system for decomposing organic compounds in water for use in semiconductor manufacturing, a chemical reactor vessel having a fluid inlet and a fluid outlet, a persulfate anion addition system upstream of the reactor vessel, and a light emitting device contained within the reactor vessel. The light emitting device provides light capable of decomposing persulfate anions.

Abstract: A drain valve for mounting as a replacement for the drain plug in the oil pan of a motor vehicle includes a body member having an upstream end threaded for attachment to the oil pan, a downstream end, and a passageway therethrough normally closed by a valve element adjacent the downstream end thereof. A valve actuator is mountable on the downstream end of the body member to displace the valve element to open the passageway, and the downstream end of the actuator receives a drain hose for directing the oil to a collection receptacle. A dust cap covers the downstream end of the valve between draining operations to protect the valve from damage.

Abstract: A high pressure fitting system includes a body having a passage therethrough to provide fluid communication between an associated fluid system and a female port. The body includes a first groove adapted to receive a seal member that defines a primary seal when inserted in the female port. A frusto-conical portion on the body cooperates with a frusto-conical region of the female port to define a secondary metal-to-metal seal. A second groove in the body receives a pressure transfer ring which is partially captured by a fastening sleeve freely received around the body. Rotation of the fastening sleeve results in axial advancement of the male fitting assembly via the pressure transfer ring to establish the secondary seal.
