Abstract: The invention relates to a coated arc splitter made of a ferromagnetic material for use in an arcing chamber. The invention provides that the arc splitter has a layer made of a composite material consisting of at least two constituents of which the first constituent is electrically conductive, has a melting point which does not exceed that of the ferromagnetic material, and has a vaporization point which does not exceed that of the ferromagnetic material, and of which the second component has a melting point higher than that of the first constituent, and has a vaporization point higher than that of the first constituent.

Abstract: An electric contact comprises a main body consisting of a copper-based alloy or of stainless steel and a contact layer consisting of a gold-based alloy. The contact layer has a thickness of at least 0.3 ?m and consists of gold with a content of 0.5 percent by weight to 15 percent by weight of one or more platinum group metals, and that an intermediate layer consisting of silver or of a silver-based alloy or of nickel is provided between the main body and the contact layer. The contact layer is preferably applied on the main body by a PVD process.

Abstract: An arrangement made up of an electrical circuit board (7) and an electrical pressure transducer (1) which has, in a housing (2), a pressure sensor onto which the pressure to be measured is transferred by means of a fluid through a channel (5) leading into the housing (2), and from which there proceed electrical lines which project out of the housing (2) as leads (4) and are connected to the circuit board (7). The channel (5) is shielded on the outer side of the housing (2) so that the flow resistance for fluid entering and leaving the channel (5) increases.

Abstract: An apparatus for monitoring tire pressure on automobiles, having an arrangement (1), intended for installation into a wheel, made up of a pressure sensor, a transmitter, and a circuit for operating the pressure sensor and transmitter, and having a battery (2) which supplies the circuit with power via a power supply line (3), the arrangement (1) and the battery (2) being located in a sealed housing (9). Located in the power supply line (3) is an electronic switch (4) which has a control electrode (5) and is nonconductive when the control electrode (5) is connected to ground.

Abstract: A method for processing signals of a tire pressure monitoring system on vehicles on each of whose N wheels (R1 through R5) a transmitter is mounted and a reception antenna (1 through 5) which is connected to the input of a common receiver (8) is allocated to each transmitter in its vicinity, the transmitters transmitting, at time intervals, data telegrams which contain an individual identifier and a data portion following the latter. The signals received simultaneously from the reception antennas (1 through 5) and having the same identifier are conveyed in summed fashion to the receiver (8), alternately from all N reception antennas (1 through 5) and from N-1 reception antennas (1, 2, 4, 5), such that the one reception antenna (3) whose signal is blanked out of the sum of the signals is selected by cyclical transposition from the total number N of reception antennas (1 through 5).
