  • Patent number: 6409839
    Abstract: A vapor generator (19, 62) and connected chemical vapor deposition chamber (28) for providing a vapor for operations such as chemical vapor deposition has an atomizer (16, 16A, 38, 50) for forming an aerosol or droplet spray (36, 58, 74, 80) separate from a vaporization chamber (19, 62). The aerosol is passed into a heated vaporization chamber (19, 62) wherein the particles or droplets are flash vaporized and larger droplets are vaporized by direct contact with heated surfaces. The resulting gas/vapor stream is then used for chemical vapor deposition, in a separate chemical vapor deposition chamber (26). The vapor and gas stream is preferably passed through a restricted passageway (22, 44, 68) for mixing before being introduced into the chemical vapor deposition chamber (26).

  • Patent number: 6299076
    Abstract: A steam cleaning system for ridding a workpiece of contaminants by directing a jet of steam onto the workpiece. The system includes a steam generator characterized by a central cavity having walls for containing water fed into it from a water inlet conduit. The steam generator includes a heating element for heating the cavity walls to vaporize water located in proximity to the walls. At least a portion of the cavity walls are provided with a thin porous layer of non-corrodible material to form a surface substantially free of major surface irregularities. The porous layer promotes water vaporization, flashing it into steam. Steam formed in the cavity may be superheated for discharge onto the workpiece through an external nozzle. The system components, including the water pump, are made of non-corrodible, preferably non-lubricated materials to prevent contamination of the workpiece and increase the service life of the pump.

  • Patent number: 6094523
    Abstract: A flash steam generator to be used as an integral component of a steam sterilizer. The generator is constructed of a metal block having a first bore drilled lengthwise through the metal block. Surrounding the first bore are a plurality of additional heater bores in which heating elements are inserted. The generator is integral to the sterilizer piping and control systems. Water is supplied to the first bore by the sterilizer piping system, and electricity is supplied to the heating elements by the sterilizer power supply. The heating elements convert the electricity to heat, which transfers via the metal block to the first bore where the heat rapidly boils the water contained therein in what is essentially a flash vaporization process.

  • Patent number: 6025577
    Abstract: An electrical sleeve heater has a tubular outer wall and a heating coil inside the outer wall. An outer sleeve inside the heating coil formed with an axially throughgoing slot having angularly confronting edges is made of a material having a high coefficient of thermal expansion. An inner sleeve inside the outer sleeve is formed with an axially throughgoing slot and with outwardly projecting lips engaged through the outer-sleeve slot bearing angularly on the outer-sleeve slot edges. It is made of a material having a low coefficient of thermal expansion so that when the sleeves are heated the outer-sleeve edges press the inner-sleeve lips together and thereby decrease the radial inner diameter of the inner sleeve.
