Abstract: A seal-less magnetically driven scraped-surface heat exchanger is provided that is particularly useful for aseptic processing. The heat exchanger comprises an elongated generally cylindrical heat transfer tube having an inlet, an outlet, and a sidewall defining a chamber between the inlet and the outlet. An elongated media tube is provided in surrounding relation to the heat transfer tube. A rotary shaft is mounted axially within the heat transfer tube. The rotary shaft has an outer surface and one or more scraper blades extending from the outer surface of the rotary shaft. A drive end containment shroud is mounted at an axial end of the heat transfer tube. The drive end containment shroud has a closed end, an open end, and a sidewall defining a drive chamber in open communication with the interior chamber of the heat transfer tube through the open end of the containment shroud. An inner rotatable magnet assembly is mounted within the drive chamber of the drive end containment shroud and connected to the rotary drive shaft. An outer rotatable magnet assembly is mounted outside the drive end containment shroud and magnetically coupled to the inner rotatable magnet assembly. In use, rotation of the outer magnet assembly results in rotation of the inner magnet assembly, which results in rotation of the rotary drive shaft.

Abstract: Apparatus for cooling a bundle of capillary tubes to prevent overheating of the tubes during a parallel capillary electrophoresis procedure. The apparatus includes a jacket of thermally conductive solid material comprising mating jacket members movable between an open position in which the jacket members are separated to allow placement of the bundle in the jacket and a closed position in which the jacket members are mated together and the bundle is disposed inside the jacket in thermally conductive relation with the jacket. Window openings in the mating jacket members define a window to permit the passage of light through the window and the capillary tubes of the bundle at the location of the window.

Abstract: A device for thawing frozen food requires no electrical energy consumption. A frozen food item is supported by a metallic bottom part and a metallic top part overlies the food item so that the food item is held in sandwiched relation between the top and bottom parts. The distance between the top part and the bottom part is vertically adjustable to accommodate frozen food items of differing sizes. A plurality of heat transfer fins are integrally formed in the top part and deliver heat from the ambient environment into the food item. A second embodiment includes fins on the bottom part as well. Moisture created by the thawing drains away from the food item under the influence of gravity.

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. When the lid housing is opened and closed, the evaporating portion of the second heat pipe is rotated within the coiled first heat pipe portion and slidably engages its circularly cross-sectioned interior side portion.
