  • Patent number: 8461491
    Abstract: An electrical heating device has an integrally manufactured support made from an insulating material. A depressed path is provided for the introduction of a coiled round heating element into the support. In the bottom side of the support, additional depressions are made in support and pass into the depressed path and form undercuts. In the area of the undercuts the heating element is flattened in the path and thereby pressed into the undercuts and consequently can be no longer moved out of said path.

  • Publication number: 20130140295
    Abstract: An object of the invention is to control the penetration of condensed water into an insulation member or a heater element in an electric heating catalyst (EHC). The EHC according to the invention includes a heater element that generates heat by supply of electric current to heat a catalyst, a casing that houses the heater element, an insulation member provided between the heater element and the casing to provide electric insulation, and an electrode connected to the heater element through an electrode chamber, which is a space located between the inner wall surface of the casing and the outer circumferential surface of the heater element. The EHC is further provided with a bypass passage, one end of which is connected to a bottom part of the casing at a position upstream of the upstream end face of the insulation member. The bypass passage bypasses the insulation member.

  • Patent number: 8444010
    Abstract: A food dispensing device having a frame with first and second sidewalls in spaced parallel relation that house a heating board and a slant board. The slant board is positioned below the heating board and both slope downwardly. Specifically, the heating board has a plurality of slots therein such that juice from a food product flows through the slots and onto the slant board. Adjacent and below the heating board and slant board is a flange that is positioned such that when a food product is placed on the heating board the food product rolls toward the flange and simultaneously juice flows from off the slant board into a juice tray disposed below the flange.

  • Patent number: 8338756
    Abstract: Apparatus for and methods of rethermalizing a package of refrigerated or frozen food are disclosed. In general, heating mechanisms are brought into conductive heat transfer contact with the package of food and operated for a duration of rethermalization time to rethermalize the package of food by heating the food to a rethermalized temperature, and then, if desired, to hold the rethermalized package of food at a desired holding temperature for a duration of holding time. The rethermalization time can be relatively short (e.g., thirty minutes or less), and the holding time can range from a very short period of time to a very long period of time (e.g., four, six, eight or more hours) without significant loss of food quality. Other features of the apparatus and methods are disclosed.
