Abstract: Disclosed is a mobile cart for an organ container. The mobile cart includes a top assembly configured to be releasably secured to the organ container, which is at least one of an organ transporter and an organ perfusion apparatus configured to perfuse an organ. It also includes a support structure attached to the top assembly so as to support the top assembly, the support structure being moveable from an extended position to a collapsed position. The top assembly in turn includes distinct primary and secondary locking mechanisms, each of which is configured to secure the support structure in the extended position. And when the support structure is secured in the extended position, both the primary and secondary locking mechanisms must be actuated for the support structure to be moveable to the collapsed position.

Abstract: A heat exchanger suitable for a vehicle includes a plurality of tubular first members arranged in a row and forming elongate gaps. These members form passageways for flow of a first fluid for heat exchange with cooling air flowing through the gaps. The first members and gaps form a primary heat exchange area. Inlet and outlet manifolds are connected to the first members for directing the first fluid through the first members. An associated cooling device circulates liquid coolant and comprises flat tube-like second members, each extending into a respective gap in a secondary area which is part of the primary area but smaller. The second members each have a thickness at least the width of their respective gaps. At least some of the first members can be formed with cut-outs in opposite flat sides, these cut-outs being sealingly closed by the second members.

Abstract: The viewing functionality of an application may be extended by use of an adapter. An application is instantiated, and the application may provide a view box that contains a scrolling feature as part of its interface. The adapter uses the application “behind the scenes” to collect information in a way that is not visible to the user. Mouse gestures may be defined to perform various viewing functions such as zooming. The adapter intercepts these gestures in the window that the user uses to interact with the application, and interprets the gestures as specific view commands (such as zoom). Based on the commands (or, possibly, in anticipation of commands that have not yet been issued), the adapter uses the application to collect content. The application then scales the content appropriately, puts the scaled content in a document, and overlays the document on top of the view box.

Abstract: A heat exchanger useful for high temperature applications such as EGR cooling and fuel reformer applications comprises a tube bundle made up of a plurality of tubes, each having at least one end expanded to an enlarged polygonal cross-section, and having central portions with a generally smaller cross section. When the tubes are formed into a bundle, the enlarged end portions nest with one another and interstitial spaces are provided between the central portions of the tube. The enlarged end portions are preferably retained by a header ring having a multifaceted inner peripheral sidewall which is adapted to form brazed lap joints with the outward facing surfaces of the peripheral tubes end portions in the tube bundle. In one preferred arrangement, axially aligned enlarged portions are provided intermediate the ends of at least some of the tubes. These enlarged intermediate portions nest with one another and eliminate or reduce the need for baffle plates.

Abstract: A headerless heat exchanger has a core comprised of a stack of flat tubes of rectangular cross section through which a first heat exchange fluid passes. The tubes are expanded in height at their end portions to provide spaces between adjacent plate pairs for passage of a second heat exchange fluid between the tubes. The sides of the tubes are coplanar, at least in the end portions of the tubes, to provide flat surfaces along which the core is sealed to side plates of the heat exchanger, for example by brazing or welding. The side plates may be separately formed or may comprise part of a continuous housing. The tubes are preferably formed from plate pairs having nesting side walls.

Abstract: A core for a charge air cooler comprises inner and outer concentric tubes providing an axially extending annular passageway for flow of a fluid, preferably a liquid coolant. A first inlet and a first outlet are provided at the ends of the axial annular passageway. Arranged on an outer surface of the outer tube is at least one circumferential fluid flow passageway for flow of a fluid, preferably air. Each circumferential flow passageway is provided with a corrugated strip fin comprising a plurality of rows of corrugations. The core is combined with an outer housing to form a heat exchanger. The housing is provided with an inlet and an outlet for the fluid flowing through the circumferential flow passageways. Other embodiments are disclosed in which the heat exchanger is adapted for use with three fluids and in which additional cooling capacity is provided by the provision of coolant passageways in the housing.

Expanded metal turbulizers are located in the flow channels. The turbulizers have portions thereof crimped closed to control the flow inside the channels and prevent unwanted bypass flow.

Abstract: A heat exchanger and method of transferring heat between fluids is disclosed using a plurality of stacked plate pairs consisting of face-to-face, mating, ringlike plates, each plate having an outer peripheral flange, an annular inner boss located in a common plane with the peripheral flange, and an offset intermediate area located between the peripheral flange and the inner boss. The peripheral flanges and inner bosses in the mating plates are joined together. The intermediate areas have outwardly disposed joined intermediate bosses having aligned inlet and outlet openings forming manifolds for the flow of a first heat exchange fluid circumferentially through the plate pairs from the inlet manifold to the outlet manifold. The heat exchanger also has a header enclosing either the inner bosses or the outer peripheral flanges to cause all of a second heat exchange fluid to pass between the plate pairs transversely relative to the flow of the first heat exchange fluid.
