  • Patent number: 7345572
    Abstract: A temperature sensor for a radiant heating element includes a first expansion element, e.g., a tube, connected to a housing of a switch, which is permanently connected to a second expansion element, e.g., a rod in the region of its free end. The two expansion elements have different thermal expansion coefficients, and the switch has at least one contact spring, which is pre-tensioned against a point and carries a contact. The contact spring is implemented as a snap spring. The first expansion element has a spring acting in its axial direction applied to it. To avoid rapid fatigue of the contact spring, the second expansion element acts on the contact spring on one side and the spring acting in the axial direction of the second expansion element acts on the contact spring on the other side, with the spring acting against the second expansion element via a support.

  • Patent number: 7214909
    Abstract: A sensor positioned between a heat source and a heating area in parallel relationship to the heating area, for determining a mean value of the temperature of the heating area, includes a ceramic element, and a temperature-dependent resistor web attached to the ceramic element and confronting the heating area at a distance thereto. The resistor web has a length of at least 200 mm, and is electrically contacted at a contact point outside a region in which the temperature is to be ascertained.

  • Patent number: 6745930
    Abstract: The invention relates to a method for attaching a first body which is of one of a metal matrix composite (MMC)-material or copper to a second body which is a ceramic member for acting as a heat sink, wherein the surface of the ceramic member which is placed against the MMC- or copper body is coated with a first metal by heating the two bodies to above the eutectic temperature of a system comprised of the matrix metal of the MMC-body or the copper of the copper body and the first metal applied to the surface of the ceramic member; and subsequently cooling the system to room temperature.
