Abstract: A pizza warmer and oven system in which a plurality of pizza warmers containing a phase change material can be charged to their preferred temperatures by resistance heaters positioned in shelves above and below each warmer in an oven. One embodiment has top shelves biased in close proximity with the warmers. Moving a lever causes the upper shelves to be raised by cams, allowing removal or insertion of warmers. Insertion of warmers into the oven trips switches, starting timing circuits which energize the heater and charging indicator lights. At the end of the timing cycle, indicator lights signal the warmer's charged condition. In another embodiment, the top shelves are gravitationally biased down but are each free to move upward slightly for warmer insertion or removal. Turning on the oven energizes the heaters. A thermostat in the heater circuit turns off the heater at a pre-selected temperature.

Abstract: A cooking apparatus in a form of a container includes an outer shell and an inner shell wherein a cavity is provided by coupling the edges of the outer and inner shells. The cavity is partially filled with a heat conductive medium, such as silicon oil. The cooking apparatus further includes an electric heating element installed under the container between the outer and inner shells. When energized, the heating element produces heat which in turn heats the silicon oil. The hot silicon oil heats the inner shell and thus cooks the food in the container. The outer shell of the container also has a pressure controlling member that is opened when a cavity pressure exceeds a predetermined value. The pressure controlling member comprises a spring housing securely affixed to the outer shell and defining a first through hole. The spring housing has a valve biased to open when a cavity pressure exceeds a predetermind value.

Abstract: An insulated case designed to keep medical pads warm and in a condition ready for application over a period of hours. The case typically includes a cover, multiple internal containers and a source of controlled heat to warm the pads. The pads, after being saturated with a medication such as alcohol, are stored in the internal containers where they are raised in temperature by the controlled heat source to a predetermined temperature range and maintain within that temperature range. At the same time, the vapor pressure is maintained at a level within the internal containers to prevent the escape of the alcohol from the pads through evaporation. The safety features of this apparatus include an over temperature alarm and automatic shut off as well as an over pressure alarm and vent, all of which operate even when there is a power failure. Internal containers are individually insulated and are removable for transport to wherever they are needed.

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. A heating element is typically disposed beneath each drawer bottom wall to apply heat to walls of corresponding sub-compartments and evenly distribute heat to intravenous solution bags contained within those sub-compartments. Each drawer is associated with a controller that controls the heating element to apply heat to the corresponding drawer sub-compartments in accordance with a comparison between desired and measured temperatures associated with that drawer.

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.

Abstract: A heating device for a titration plate enables selected sample wells to be thawed by providing an array of individually energizable heat sources each capable of heating a single sample well. A cold plate serves to maintain all other samples in their frozen state.
