  • Patent number: 4361954
    Abstract: In a method for the production of toaster heating elements firstly connecting strips made of electrically conductive material are arranged in the region of edge recesses at opposite edges at the rear side of a support plate, opposite to the heating side. Then a plurality of heating conductor wires are provided substantially parallel to one another and in such a way that they cross the connecting strips in the region of the edge recesses at the heating side and thereby are electrically connected to said strips. Furtheron the wires are cut off. In an apparatus for performing the method there is provided a processing station comprising a supporting surface for the support plate of the heating elements. The processing station further comprises housing grooves one for each connecting strips. Said grooves are situated at opposite side edge regions of the supporting surface. Further a delivery station associated with the processing station is provided.

  • Patent number: 4352008
    Abstract: An electric heating device for heating the interior of a cabinet containing electrical apparatus, such as a switch or distribution apparatus, to prevent sweating or condensation therein, includes at least one PTC electrical resistance heating and temperature self-regulating heating element situated in the interior of an elongated body made of thermally conductive material that is thermally connected to a radiator. The radiator is formed by a pair of flat base plates extending laterally from opposite sides of the body and radiator fins extending only from the base plates and only from one flat side thereof. The body is a massive hollow element having a wall thickness greater than that of the base plates and fins and a height greater than the thickness of the base plates. The body, base plates and fins are formed as a one piece extrusion. A permanent magnet may be used to secure the body to the interior surface of a steel cabinet.
