  • Patent number: 6951065
    Abstract: Method and apparatus for drying granulate material in a hopper by controlling the amount of gas which flows through the hopper to heat and to dry the granulate. The control allows to use a minimum amount of gas for heating the granulate to the drying temperature and to dry it with an optimal low energy consumption. This effect is reached by controlling the amount of gas flowing through the drying hopper as a function of the temperature difference between the temperature of the heating gas leaving the drying hopper and the granulate to be heated.

  • Patent number: 6161311
    Abstract: An apparatus and method for reducing particles in reactors. The apparatus includes an enclosure for processing the semiconductor wafers. The enclosure has a wafer handling chamber connected by an isolation gate valve to a processing chamber. Additionally, the apparatus includes pipes for delivering a purge gas into the wafer handling chamber. The purge gas is used to eliminates particles from the enclosure. The apparatus also includes a pilot operated back pressure regulator for regulating the delivery and removal of the purge gas from the enclosure. The apparatus actuates the isolation gate valve in a controlled rate to reduce disturbances from the purge gas entering into the enclosure. The apparatus also includes a Bernoulli wand for lifting and holding a single semiconductor wafer. A dome loaded regulator is used to control the ramp rates of the gas to the Bernoulli wand. The dome loaded regulator is actuated by a pilot gas.

  • Patent number: 5640784
    Abstract: Drying apparatus including pressure control of air supply feeding an air bar and subsequently impinging upon a web, so as to avoid or compensate for web shift without disturbing the cushion pressure and flotation techniques necessary for adequate web flotation and drying, as well as a method of regulating the pressure of supply air to such air bars. A damper or valve is positioned in the header system between first and second ducts feeding each air bar. Proper adjustment of the damper regulates the pressure of supply air in each duct, and compensates for web shift or minimizes or prevents web shift from occurring.
