Abstract: A transmission module for transmitting torques having a base, a first drive shaft, a second drive shaft parallel thereto, a first output shaft and a second output shaft, both rotatable about a common axis, the axes of the drive shafts are arranged parallel to the axis of the output shafts, a gear unit, where the two drive shafts, the gear unit and the first output shaft are rotatably supported in the base, and the second output shaft is rotatably supported in the first output shaft and the gear unit is designed in such a way that a synchronous rotary movement of the two output shafts can be effected by a rotary movement of the first drive shaft and a relative rotary movement of the two output shafts can be effected by a rotary movement of the second drive shaft.

Abstract: The calibration weight arrangement for an electronic balance with a force-transmitting device (1), includes a calibration weight (14) capable of coupling to the force-transmitting device (1). The calibration weight (14) is moved vertically by a transfer mechanism and a drive source to establish and to release the force-transmitting contact between the calibration weight (14) and the force-transmitting device (1). The transfer mechanism has at least one resetting element (22, 37, 38, 40, 43) and a lifting system configured as a knee joint linkage (17, 117, 217). The resetting element (22, 37, 38, 40, 43) and the lifting system work together to arrest and cushion the calibration weight (14) if the balance is shocked, dropped or hit.

Abstract: An electronic balance with a force-transmitting device (1, 101) has a calibration weight arrangement (4, 104). The arrangement includes a calibration weight (3, 103) capable of being coupled to the force-transmitting device (1, 101). It also includes a transfer mechanism and a drive source to effect a guided movement of the calibration weight (3, 103). The drive source has an actuator (16) that cooperates with the transfer mechanism and consists, at least in part, of a shape memory alloy. The actuator (16) moves the calibration weight (3, 103) through a structural change of the shape memory alloy as a result of a temperature change.
