  • Patent number: 6605475
    Abstract: Apparatus and methods have been developed to deliver automatically a sample to a reaction vessel, an analytical device or any location where sample introduction or deposition is desired. A sample delivery system of the invention generally includes a housing defining a channel, e.g., a capillary, and a volume controller, which is a temperature control device, in thermal communication with the channel. The channel preferably is closed at one end, and contains an opening for introduction of a sample. The closed end of the channel is associated thermally with the temperature control device. The temperature control device heats and cools a thermally expandable fluid in the channel which controls movement of a sample into, within and out of the channel.

  • Publication number: 20030116559
    Abstract: A method of producing a thin film heating element is provided which can be used in manufacturing a transparent thin film heating element of desired shape with an increased heat emission property and an excellent durability. Also provided is a heating device of the type incorporating the thin film heating element produced by this method. The inventive method comprises the steps of, applying heat- and oil-resistant ink on a predetermined surface area of a base element, allowing the ink to run dry, spraying conductive chemical composition on the base element to form a conductive thin heater film, removing the ink out of the base element, printing a thin film electrode leading to the thin heater film, and baking the base element into a thin film heating element.

  • Publication number: 20020191970
    Abstract: An assembly for changing the temperature of ultrahigh-pressure fluid as it flows through ultrahigh-pressure tubing includes several thermally conductive blocks. Each block has a first bore through which the ultrahigh-pressure tubing passes, and a second bore containing a source of heating or cooling. Alternatively, resistance heating is used to increase the temperature of the ultrahigh-pressure fluid, by coupling electrodes to the outer surface of the tubing. The ultrahigh-pressure fluid is heated or cooled after it is pressurized, and is then discharged from the ultrahigh-pressure tubing at a selected temperature for use. For example, the ultrahigh-pressure fluid at a selected temperature may be discharged through a nozzle to form an ultrahigh-pressure fluid jet to cut or clean any desired surface or object, or it may be discharged to a pressure vessel to pressure treat a substance.

    Abstract: A particulate material heating system and method for heating particulate material having a core which is heated to a predetermined temperature. The core has a plurality of serpentine passages which receive particulate material from a metering device having a plurality of gears which meter the particulate material into the serpentine passages. Gravity causes the particulate material to pass through the serpentine passages such that the particulate material is agitated as it passes through the serpentine passages, thereby causing a substantial portion of the particulate material to come into contact with the core and become heated.

  • Patent number: 5949958
    Abstract: The present invention is a flash steam generator (10) to be used as an integral component of a steam sterilizer (30). The generator comprises a metal block (11) having a first bore (12) drilled lengthwise through the metal block (11). Surrounding the first bore (12) are a plurality of additional heater bores (14) in which heating elements (15) are inserted. The generator is integral to the sterilizer piping (31, 34) and control systems. In a preferred form, the first bore (12) provides a non-linear flow path. For example, a packing material such as monel wool (41) or a spiral dowel (45) can provide such a tortuous flow path. Alternatively, the block (11) may be provided with a plurality of fluid containing bores (51, 57, 67, 73, 81) interconnected by manifolds (59, 69, 75, 83).

  • Patent number: 5934562
    Abstract: An air pre-heating apparatus useable for pre-heating air supplied to one or more hot melt adhesive dispensing nozzles mounted on an adhesive supply manifold. Air is supplied from an air supply inlet on an outer portion of an outer heating member to an air supply outlet on an inner heating member having a heater therein. The outer heating member formed of a plurality of laminated plates having one or more air flow paths, which include preferably a serpentine air flow path portion that increases the residence time of the air therein. The air is supplied through the apparatus against a decreasing temperature gradient whereby heat is increasingly added thereto before the air is supplied to the nozzles. The apparatus is preferably thermally isolated from the manifold to permit maintaining the pre-heating apparatus at a temperature different than a temperature of the manifold.
