Patent number: 4398991Abstract: A heating plate, especially for presses utilized to bond two belt ends together, e.g. in the formation of an endless conveyor belt or in the repair of a conveyor belt. According to the invention, the heating effect over the plate which is rectangular or of rhombic configuration, is held uniform by distinguishing between longitudinal edge zones, transverse edge zones, central zones and corner zones, all of which have essentially the same specific volume of material, i.e. the same volume of material with a unit area of the heating surface. A frame work of longitudinal and transverse edge members of the same cross section and intermediate members parallel to the longitudinal edge member and equidistant from one another is sandwiched between a heating plate and a cover plate and the heating elements lie adjacent the heating plate in the spaces between the longitudinal and intermediate members.Type: GrantFiled: October 23, 1981Date of Patent: August 16, 1983Assignee: Wagener Schwelm GmbH & Co.Inventor: Peter Thies

Patent number: 4241650Abstract: An apparatus for cooking or otherwise heating food held in a container which includes upper and lower housing portions. Heating elements are located in the respective housing portions, and the opposed inner walls of the housing portions are adapted to be moved into contact with the food container. The heating elements are positioned immediately adjacent these walls, and these elements are substantially insulated from other portions of the housing. The intimate contact between the inner walls and the associated heating elements causes the food to act as a heat sink whereby the food is rapidly heated in a highly effective manner. The apparatus is particularly useful for the cooking of frozen food located in an appropriate container. Means are provided for retaining the upper housing in spaced apart relationship with the lower housing to permit baking and similar heating.Type: GrantFiled: June 7, 1976Date of Patent: December 30, 1980Inventors: Raymond John, Jerome G. Apfelbaum, Robert L. Moore

Patent number: 4041277Abstract: A portable tray warming unit comprising a casing having at least one tray supporting rack, trays to be supported and received upon said rack, and electrical terminal means for interconnecting the tray warming unit with an external electrical source of energy. The casing of this tray warming unit has dimensions and weight small enough so that the unit may be easily carried about or lifted. The upper and lower surfaces of the casing lie in planes parallel to each other so that one unit may be stacked on top of another. To further facilitate such stacking the bottom surface of a unit has protrusions extending downwardly from the bottom and these protrusions correspond to indentations in the top surface of the casing. This correspondence allows the protrusions of one unit to fit into the indentations of the unit on which it is stacked thereby assuring a non-slidable connection between the two units.Type: GrantFiled: June 18, 1976Date of Patent: August 9, 1977Assignee: Sweetheart Plastics, Inc.Inventors: George Shumrak, Anthony Mack
