A thermal fuse for an electrical circuit is described, with a contact arm by way of which two electrical conductors are electrically conductively connected to each other, wherein the connection of the contact arm to at least one of the two conductors is a soldered joint, which loses its strength when a activation temperature of the fuse is reached. In accordance with this disclosure a permanent magnet is provided, which generates a magnetic force, which lifts the contact arm from at least one of the two conductors as soon as the soldered joint loses its strength.

Thermal fuse

Device for creating a temperature gradient, especially in gaseous media, comprising at least one ohmic resistor and at least two non-conducting insulators and at least one casing and at least one elastic element positioned between the non-conducting insulator and the casing.

Device for producing a temperature gradient

A heating flange especially for the preheating of the intake air of an internal combustion engine with a frame (), a supporting ceramic element () with a heating band () fitted thereto. The supporting ceramic elementis held in the frame at an inner side of the frame, and a support spring () is arranged between the supporting ceramic element () and the inner side of the frame. The support spring () is a leaf spring which is straight in the non-stressed state, and sits under an initial prestess between the supporting ceramic element () and the inner side of the frame. As a result of this configuration, low friction arises between the supporting ceramic element () and heating band (), as well as leaf spring (), which reduces failures due to vibratory loading, and a defined initial spring tension with a defined spring deflection is produced.

Heating flange

A heating element for preheating intake air for an internal combustion engine and having a housing for attaching the heating element to an air intake line of the internal combustion engine. At least one heating strip (), which runs in windings (), is held in the housing and is provided with electrical terminals () that lead from the housing to the outside. The heating strip () is held in the housing by a support () running between two housing walls, which runs, electrically insulated, through the windings () of the heating strip ().

Heating element for preheating intake air for an internal combustion engine

A heating element and a process for conducting the operating heat of a semiconductor switch to a heating cell which is triggered by the semiconductor switch via first and second heat and current conducting material strips and a frame terminal with an interposed heat-conducting insulating film. The semiconductor switch is provided with a cooling fin and is applied directly to a surface of the first heat and current conducting material strip.

Electronic triggering for heating elements

Cold starter for use with a diesel engine having a combustion chamber, an intake air channel, and an air filter, which includes an electrical heating device mounted either in the intake air channel or within the air filter casing.
