  • Patent number: 7896947
    Abstract: An air filtering apparatus including an electrolytic bath for electrolyzing water to generate electrolytic water, a gas-liquid contact member in which the electrolytic water generated in the electrolytic bath infiltrates and an air blowing fan for blowing air to the gas-liquid contact member is equipped with a water circulation passage through which the electrolytic water is supplied/circulated to the gas-liquid contact member, the electrolytic water passing through the gas-liquid contact member is received and stocked by a water receiving tray and the stocked electrolytic water is pumped up and supplied to the gas-liquid contact member, a drain pipe branched from the water circulation passage, a water stop valve for opening/closing the drain pipe, and a drain receiver for receiving and stocking the electrolytic water discharged from the drain pipe when the water stop valve is opened.

  • Patent number: 6391093
    Abstract: A weld chamber has an air intake and an exhaust or evacuating ductwork for evacuating gases and other particles from the welding chamber. The evacuating ductwork is connected to a vacuum source to remove gases and by products from the weld chamber during welding. A throttle plate is provided in the evacuating ductwork adjacent the weld chamber to adjust or regulate the air velocity evacuating from the weld chamber. The evacuating duct then leads to a sealed water filtering tank. All of the exhausted/evacuated gases and by products are led beneath the water line and bubble through the water before emerging from the sealed water. The soot and iron particles are immediately cooled and trapped in the water tank. Moreover, particles become wet and are less likely to become airborne thus leading to a substantial portion of the particles being trapped in the sealed water tank. Thee remaining gases are then evacuated to the vacuum source and further filtered by a mechanical filtration device.

  • Patent number: 6078846
    Abstract: The non-contact sensor employs a structured light source that emits light in a predefined planar configuration and an optical receiver for reading reflected light produced by the structured light source within a predefined field of view. A tetrahedron target structure includes a three-dimensional framework that defines at least three non-collinear, non-coplanar structural lines each simultaneously visible to the sensor. A calibration system is coupled to the gauging system and the non-contact sensor for calibrating the gauging system by evaluating the geometric relationship of the structured light reflected from the structural lines of the target structure to determine the position and orientation of the target structure and then correlating the structural lines to the gauging system.
