    Inventors: Richard M. Shelley, Matthew Lee Rix
  • Patent number: 5743942
    Abstract: Formed is a new desiccant film made of an uncoated microporous film secured to an uncoated laminate film wherein the inner surface of both the microporous film and the laminate material are compatible. This film is less expensive to form and produces a stronger bond than conventional coated materials used for desiccant packaging.
    Type: Grant
    Filed: September 19, 1996
    Date of Patent: April 28, 1998
    Assignee: United Catalysts Inc.
    Inventors: Richard M. Shelley, Matthew Lee Rix
  • Patent number: 5145641
    Abstract: An autoclave has a water level sensor in a water reservoir in the pressure vessel. An external water tank is connected to the reservoir via an electrically-operated valve. An electrical resistance heating element in the reservoir heats the sensor if it indicates a full level at the start of operation, in order to dry any exposed part of the sensor and thereby prevent an erroneous output from the sensor caused by water clining to it. This heating of the sensor can be repeated if it continues to indicate a full level. If a low level output is produced by the sensor, the valve is opened to allow water to flow from the tank to the reservoir. If the valve remains open for longer than a predetermined time without the sensor indicating a full level, the autoclave produces a fault signal.
