  • Patent number: 10376097
    Abstract: A vertically adjustable upper platen is useable with, e.g., a clamshell-type steam griddle, in which the vertical position of the upper cooking surface can be precisely and repeatably controlled. The upper platen includes a vertical adjustment mechanism which utilizes multiple mechanical reductions to facilitate rapid and precise adjustments of the vertical platen position in small increments, while retaining traditional and cost-effective control mechanisms and motors. The vertically adjustable platen may also include a leveler assembly which allows the upper platen to self-adjust into a level orientation relative to the lower platen when the upper platen is lowered into contact with the lower platen, and then hold the level orientation when the upper platen is raised to create a cooking space between the upper and lower cooking surfaces.

Each end of the wire mesh is coupled to an electrical contact. The electrical contacts are preferable positioned at an exterior portion of the integrated device to be easily placed in electrical contact with a voltage source. As current passes through the mesh, heat is produced. The heat passes from the mesh to each of the flow-through tubes via the thermal interface. The flow-through tubes can be fluidically coupled to a sample preparation module. The sample preparation module, the flow-through tubes, and the heater can be integrated within a single integrated device that provides automated sample preparation and thermally-driven chemical reactions for a variety of applications.

  • Patent number: 6170389
    Abstract: A cooking appliance having an upper cooking unit pivotally mounted on a lower cooking unit for rotation substantially about a horizontal axis into three different positions, a first position in which the upper cooking unit is on top of the lower cooking unit to form a contact grill, a second position in which the upper cooking unit is substantially horizontally oriented with and parallel to the lower cooking unit to form therewith a double grooved griddle, and a third, generally upright, position intermediate the first and second positions to provide access to the lower cooking plate when the appliance is being used as a contact grill. The cooking plates have elongate grooves which are generally parallel to an axis of the hinge that connects the upper and lower cooking units together and which grooves increase in depth from one side of the cooking appliance to the other for carrying liquid cooking byproducts away from the food being cooked.

  • Patent number: 6147331
    Abstract: A band heater includes a shoe assembly comprising a plurality of arcuate shoe segments each having a pair of outwardly-projecting extensions and a channel segment formed between the extensions. A strap assembly generally encircles the shoe assembly for retaining same in a circular configuration on an object to be heated. The strap assembly includes opposite side edges which are captured in slots formed by the shoe segment extensions. The strap assembly is thus retained generally within a continuous, annular channel formed by the shoe assembly. The strap assembly side edges can slide longitudinally within the shoe segment extension slots whereby relative movement, for example, due to thermal expansion and contraction, is accommodated. A thermal control unit, such as a tubular electric resistance heater, is located generally within the shoe assembly for conductivity heating same and is generally covered by the strap assembly.

  • Patent number: 5397875
    Abstract: A portable appliance for heating towels and for dispensing heated fluid such as body oil has a suitcase-like housing with hinge-connected base and lid components that define a plurality of compartments for heating towels and liquid when the housing is "open" and the appliance is "set up" for operation, and for receiving components of the appliance so that the appliance can be conveniently stored and transported when the housing is "closed." When the housing is open, a support structure such as a set of legs is removable from the housing for use in supporting at least a base portion of the housing at an a convenient access height above a floor or other substantially horizontal surface. A relatively large main compartment is defined by the housing for receiving and suitably heating towels therein for use in concert with the administration of a massage. "Wet" or "dry" towel heating can be carried out within the main heating compartment.

  • Patent number: 5380986
    Abstract: A portable multi-purpose electric fast cooking apparatus for use in cooking a variety of foods by various methods. The apparatus includes a pair of hinged pan-shaped housing members having a bottom wall and a side wall which can be pivoted between a closed position superposed one above the other in opposed facing relation and an open position laterally adjacent one another, and each housing has a laterally extending handle to serve as a carrying handle when the housing members are in the closed position. A heating plate is carried by each housing member and each plate has a heating element secured to its underside and an outward facing side with a central depressed flat surface surrounded by a raised side wall and shoulder at the top thereof. Each heating element is individually controlled by a separate thermostat. In the closed position, the depressed flat surfaces, surrounding raised side walls and shoulders define a central cavity.
