  • Patent number: 6384380
    Abstract: A temperature control system includes a cabinet or system housing having a plurality of heating compartments for containing intravenous solution bags or other medical items. Each heating compartment is independently heat controlled via a controller, and includes a heating assembly including a heater, a U-shaped heating plate, a temperature sensor and a cut-out switch for disabling the heater when a threshold temperature is exceeded. The desired or set point temperature for each heating compartment may be independently entered to the controller via an input device. The heating plate has a generally U-shaped configuration with a thermally conductive bottom wall and thermally conductive side walls extending therefrom. The heater is typically affixed to the underside of the bottom wall, wherein, upon heating of the bottom wall, heat is conducted through the side walls to provide an even distribution of heat to medical items placed within the heating compartment.

  • Patent number: 6262394
    Abstract: An oven for maintaining cooked foods at temperatures suitable for serving the foods or even for cooking foods has a cabinet containing multiple heat sinks of channel-shaped configuration. The ends of the heat sinks open out of the cabinet, so that any heat sink may receive a tray of food from either the front or back of the cabinet. The interior surface of the heat sinks generally conform to the cross-sectional shapes of the trays, so that the heat sinks lie along the bottoms and sides of the trays. The heat sinks have a heating elements extended along their sides and bottoms for elevating the temperature of the heat sinks and directing heat into the trays within the heat sinks. In addition, each heat sink also contains a cover which may close the top of the tray in the heat sink and thereby retard the escape of moisture from the tray or may vent the interior of the tray.

  • Patent number: 6259067
    Abstract: A temperature control system includes a cabinet or system housing having a plurality of drawers for containing intravenous solution bags or other medical items. Each drawer is individually controlled, and generally includes a window and a plurality of sub-compartments with each sub-compartment accommodating an intravenous solution bag or other medical item. The drawers are each pivotable relative to the system housing to permit access to the sub-compartments, while the drawer windows enable the intravenous solution bags to be viewed during heating.

  • Patent number: 6099653
    Abstract: A liquid reagent delivery and vaporization system, including a housing defining a flow passage for flow of a process fluid therethrough. A vaporizer element is positioned within the housing and includes a heated vaporization surface. Liquid reagent is selectively delivered to the heated vaporization surface, to vaporize the liquid reagent and form reagent vapor for flow through the flow passage of the housing, e.g., to a chemical vapor deposition reactor for deposition of a film on a substrate. A thermal damping fluid source is arranged to selectively deliver a thermal damping fluid into the flow passage to maintain a predetermined thermal condition therein. For example, the system may be arranged to selectively terminate delivery of liquid reagent to the vaporization surface and to contemporaneously selectively initiate delivery of the thermal damping fluid into the flow passage to maintain a thermal condition thermally matches the vaporization conditions when the liquid reagent is vaporized.

  • Patent number: 4567649
    Abstract: A turbine rotor disassembly, handling and reassembly apparatus employs a feedback-controlled electric heating oven to rapidly heat a turbine wheel while the rotor shaft is in the horizontal position. An adapter interfaces the wheel to a handling spool whose outboard end is adjusted to slide on the rotor shaft and to provide a fulcrum for supporting the wheel. A handling trolley includes a soft hydraulic system for supporting the weight of the wheel to avoid damaging the precision machined surfaces of the shrink-fit area while the wheel is being withdrawn. The handling apparatus also provides means for upending, or rotating, the removed wheel through 90 degrees to place its axis vertical for facilitating handling. A sensor system senses a radial motion of the wheel to detect clearance and to establish an appropriate fluid pressure to just balance the weight of the wheel and attached parts. The handling system includes means for rotating the wheel slightly during reassembly to align keyways or the like.
