Abstract: There is provided a resonance transducer including a main bridge linked with an input signal. The resonance transducer includes a transformer assembly across which an output signal can be tapped, a resonance circuit and a control circuit. In this arrangement, the transformer assembly is linked with the main bridge and the resonance circuit, the resonance circuit is further linked with the main bridge and the control circuit, and the control circuit is further linked with the main bridge.

Abstract: The invention relates to a clutch (2), especially for motor vehicles, for the torque connection of at least two drive parts which are rotatable about a rotational axis (4), comprising at least one clutch device (6) with a first clutch body (8) with at least one first clutch surface (12) and a second clutch body (10) with at least one second clutch surface (14), with said first and second clutch body (8, 10) being coaxially displaceable relative to each other by means of an actuating means (24) and said first and second clutch surface (12, 14) being mutually connectable in a non-positive way in at least one clutch engagement position, with the actuating means (24) comprising at least one ring gear (26) which comprises a ramp mechanism (28) and is twistable about the rotational axis (4) by an actuator (40), which mechanism, in the clutch engagement position, presses the first clutch body (8) against the second clutch body (10).

Abstract: The present invention relates to a method for converting thermal energy into mechanical work with the following steps: supply of a hot heat transfer medium to a first working chamber of a first heat exchanger (1a); isochoric heating of a first quantity of a working medium in a second working chamber of the first heat exchanger by the heat transfer medium; repeated performance of the following sub-steps: allowing the transfer flow of at least a partial quantity of the first quantity of the working medium from the second working chamber (3a; 3b) of the first heat exchanger or the preceding heat exchanger to a second working chamber (3b; 3c) of a further subsequent heat exchanger (1b; 1c); isochoric heating of the transferred partial quantity of the first quantity of a working medium in the second working chamber (3b; 3c) of the further subsequent heat exchanger (1b; 1c) by a heat transfer medium present in a first working chamber (2b; 2c) of the further subsequent heat exchanger (1b; 1c); connecting the
