  • Patent number: 6398196
    Abstract: A steam humidifier for use with a forced air heating system includes a steam nozzle mounted in the plenum of the heating system and connected to a water feed line connected to a continuous pressurized water source. The water feed line is made of a thermal conducting material and is coiled about a heating element wherein the heating element and conductive coil are substantially surrounded by an insulation barrier. The water feed line is controlled by a solenoid operated valve that will be activated only when the heater is on and a humidistat detects that humidity is required by the area being serviced by the forced hot air system.

  • Patent number: 6398846
    Abstract: A semiconductor manufacturing system includes a getter-based gas purifier coupled in flow communication with a gas distribution network for a semiconductor fabrication facility. The gas distribution network supplies purified gas to at least one wafer processing chamber in the semiconductor fabrication facility. The gas purifier includes a getter column having a metallic vessel with an inlet, an outlet, and a containment wall extending between the inlet and the outlet. Getter material which purifies gas flowing therethrough by sorbing impurities therefrom is disposed in the vessel. A first temperature sensor is disposed in a top portion of the getter material. The first temperature sensor is located in a melt zone to detect rapidly the onset of an exothermic reaction which indicates the presence of excess impurities in the incoming gas to be purified. A second temperature sensor is disposed in a bottom portion of the getter material.

  • Patent number: 6391096
    Abstract: A tubular membrane extractor column is connected to an oil filled electrical component such as a transformer. Fault gases dissolved in the transformer oil are extracted from the oil in the separator and are isolated in a second phase. Oil and second phase gas are circulated in separate flow paths until equilibrium is reached. Equilibrated gas is routed to a gas chromatograph or other analytical instrument requiring controlled fluid flow, and which incorporates a manifold assembly that eliminates the need for many of the external fittings and connections required in the instrument. A manifold block has plural fluid flow paths formed therethrough to route fluids to selected components. A collar mates to the block and adapts to a rotary injection valve to provide the continued fluid paths from the block to the injector valve and the other components of the instrument.

  • Patent number: 6390454
    Abstract: Liquid distributors collect liquid falling out of the spout group at the ends of a downcomer of a fractionation tray. The devices then distribute the liquid against the wall of the column or onto the decking of the next lower tray so to cause uniform liquid flows across the terminal decking section of the next lower multiple downcomer tray. The apparatus improves the liquid flow path on the terminal decking section of the tray, thus increasing the overall efficiency of the tray.

  • Patent number: 6375695
    Abstract: Filter has a filter main body, a container, a first counter room, and a second counter room. A counter air is introduced into the first counter room through the counter air discharge valve, and fine particles trapped in the filter main body are removed and transported to the second counter room. Then, the removed fine particles are further transported to a process portion isolated from an exhaust gas passage, and the fine particles are fired in the process portion. Since the process portion is isolated from the exhaust gas passage, the fine particles in the process portion are not returned to the filter main body. Moreover, since the fine particles are transported by the counter air only to the second counter room, it is possible to reduce an amount of the counter air.

  • Patent number: 6371455
    Abstract: A gas/liquid contacting apparatus is provided wherein sedimentation of particulate solids at the corner of liquid overflow weirs of perforated trays is substantially reduced. This is achieved by bowing outwardly in a downstream direction the overflow weirs, to even out the liquid flow over them, and providing downcomer chutes from the weirs, which conform to the weir contour at the upper end. The downcomer chutes have sides converging in a downstream direction on a base to draw liquid away from the weir sides. The invention may be used in a single, two or four pass gas/liquid contacting apparatus.
