  • Patent number: 6959756
    Abstract: Featured is a heat transferring device being configured and arranged so that at least some of the heat energy being generated by a heat producing device, such as the a bearing assembly of a flywheel energy storage system, is communicated directly from the locus of the device directly to a heat sink structure remote from the locus of the device. The heat-transferring device includes one or more flexible thermally conductive members, one end of each being thermally coupled to the heat generating device and the other end of each being thermally coupled to the heat sink. The flexible member also is configured and arranged so as to allow relative motion between the heat generating device and the heat sink in or about one or more directions or axes. The heat-transferring device further includes first and second conductive members that are each configured and arranged to thermally couple each flexible member end to one of the heat producing device and the heat sink.

  • Patent number: 6941873
    Abstract: A steam cap for use in cleaning out a tank, such as a railroad tank car, is described herein. The steam cap of the invention is preferably affixed to a tank outlet, such as a tanker outlet leg. The steam cap includes a body, preferably made of a drain cup and a line cuff, wherein the body is adapted to be secured to the tank. A delivery pipe extends into an interior space defined by the body. The drain cup defines an annular space around the delivery pipe. A condensate drain line communicates with the annular space. The condensate drain line extends outwardly from the drain cup. In use, steam or other material, delivered to the tank through the delivery pipe condenses on the tank walls and collects at a bottom of the tank. The condensate drains out of the tank outlet into the annular space in the drain cup. Condensate is then drained out of the annular region of the interior space through the condensate drain line or through a perforation.

  • Patent number: 6883588
    Abstract: Heat dissipating apparatus or system for dissipating heat generated by a payload on a spacecraft having a plurality of surfaces. The system includes at least one radiator-condenser coupled to one or more of the surfaces of the spacecraft and a heat pump including an evaporator, a compressor, and an expansion valve coupled in a closed-loop manner to the radiator-condenser. The system components are coupled together using small diameter, thin- and smooth-walled tubing. The system enables the radiator-condenser to be elevated above the source or payload temperature, and, along with the use of thin walled tubing, reduces the mass of the spacecraft. Because the radiator-condenser temperatures are elevated, multiple surfaces of the spacecraft (west, east, earth and aft) can be effectively used as radiating surfaces.

In a preferred embodiment, gas at one end of a piston flows into a piston chamber and passes radially through a plurality of axial slots formed through the piston sidewall and into a gap between the piston sidewall and the surface of the housing in which the piston slidably mounts. Between each pair of through-slots, longer axial slots are formed that extend only partially through the sidewall radially, and almost the entire length of the piston. Thus, around the circumference of the piston the slots alternate in structure between through-slots and longer slots. Gas that enters the gap through the through-slots flows circumferentially through the gap and into the longer slots. The gas exits the longer slots at the opposite end of the piston from the first gas space.

    Abstract: The present invention is a segmented flow device for performing the functions of a reactor, heat exchanger or holding tube or their combination. The device controls the residence time of all of liquid and solid particles which make up a flow in the device. By controlling the residence time, the prediction of residence time becomes less of an issue during processing. The segmented flow device reduces the difference in residence time between the fastest and slowest moving particles of the flow. The device allows all of the particles to receive nearly the same processing time to reduce under-processing or over-processing of the particles If desired, the device allows the residence time of the larger solid particles to be controlled to be longer or shorter than the average of the residence time of other particles of the flow, such as the liquid and smaller solid particles.

    Abstract: An endless conveyor belt has a thermal fluid (gas or liquid) sprayed against a portion of its underside to define a temperature-controlled region of the belt. To prevent the lateral escape of the thermal fluid, stationary seals are provided which contact the belt underside adjacent respective longitudinal edges of the belt. To keep the seals in continuous contact with the belt, despite warping that might occur, the seals carry magnets, and the belt is formed of a magnetizable material. Hence, the magnets force the belt and seals together.

  • Patent number: 6253836
    Abstract: A notebook computer has a base housing with a heat-generating microprocessor therein, and a lid housing pivotally connected to the base housing. Operating heat from the microprocessor is transferred to the lid housing, for dissipation therefrom, via a specially designed thermosyphoning heat pipe structure formed from first and second heat pipes. The first heat pipe representatively has a rectangular cross-section, an evaporating portion thermally communicated with the microprocessor, and a coiled condensing portion centered about the lid hinge line and having a circularly cross-sectioned interior side surface portion defined by flat sides of the first heat pipe. The second heat pipe has a circular cross-section, an evaporating portion pivotally received within the coiled first heat pipe portion, and a condensing portion thermally communicated with the lid housing.

  • Patent number: 6145331
    Abstract: A heat recovery management system for transferring an image to a print media in a development system of the type having an intermediate belt. The system comprises a first station that receives an energy-transfer medium to heat the belt at a first position utilizing heat from the energy-transfer medium. The first station outputs the energy-transfer medium with a reduced heat content and a second station receives the reduced heat content energy-transfer medium from the first station. The second station absorbs heat from the belt at a second position after which the second station outputs heat enriched energy to the energy-transfer medium and circulates the heat enriched energy-transfer medium back to the first station.

  • Patent number: 6141214
    Abstract: Cooling apparatus for electronic systems and a computer system with such apparatus is disclosed. The apparatus dissipates heat from circuit boards of such systems to the surroundings, thus effectively cooling the circuit boards. The cooling apparatus has a cooling unit, having a board seat defined in its bottom and side walls and seating a circuit board in the seat. A fan is exteriorly seated on the unit at a position opposite to the board seat. An air passage extends from the fan to the board seat, thus dissipating heat from the circuit board to the surroundings using air. Such a cooling unit is detachably set in the main body of a computer system with both a central processing board being seated in the board seat of the unit and a system board being set in the main body.

  • Patent number: 6141216
    Abstract: A notebook computer has a base and a cover that is pivotally mounted to the base with a hinge. An integrated circuit chip is mounted to the base and has one end of a heat pipe attached to it or to an associated heat dissipation device. The other end of the heat pipe lies along the hinge. A spreader plate is mounted in the cover and attached to the other end of the heat pipe to form a nested, rotational joint. One end of the plate is located along the hinge and formed into a slotted cylinder. The heat pipe is pressed into the slot to form the joint which is tight around the heat pipe, but still allows it to rotate to accommodate the pivot motion of the cover. A retainer may be incorporated into the design to further enhance the strength of the joint and assure thermal continuity. The retainer is a hollow cylinder with an axial slit through which the plate extends.
