Abstract: The invention relates to a linear actuator (1), at least including a stator (3) that is placed within a cartridge-like casing (2), a bearing ring (4) with a bearing seat for mounting a rotor (5) with an antifriction bearing (6), a spindle (7) that on its drive side (7.1) is together with the rotor (5) designed as motion transformer to transform the rotary motion into a translatory motion and a flange (9) that closes the casing (2) on the output side (8) of the linear actuator (1), the flange (9) being equipped with an anti-rotation locking device for the spindle output side (7.2) that penetrates the flange (9). According to the invention the cartridge-like casing (2) is provided with several formed bending tongues (10.1, 10.2), whereby in assembled condition first bending tongues (10.1) engage with groove-like recesses (11) of the bearing ring (4) of the antifriction bearing (6) and second bending tongues (10.

Abstract: The invention relates to an integrated gas regulating and safety valve for burners of a modulatable gas heating device. According to the invention, the gas regulating and safety valve comprises a housing (1) with two controllable closing elements, the axes of which are spaced apart from each other and extend one behind the other in series in the direction of gas flow between an inlet channel (2) and an outlet channel (4) of the housing. In the de-energized state, the two closing elements abruptly close the gas regulating and safety valve independently of each other, in each case by means of an associated spring element (7, 12). The first closing element, additionally serving for the modulation of the gas stream, has a drive spindle (15.1), which is formed as a spindle of a stepping motor (15), is surrounded by an excitation winding (16) and has placed on its end a restrictor component (8) and, at a distance from that, the first spring element (7).

Abstract: The invention relates to a poisoning apparatus (1) for laboratory and medical devices, with a support (2) having a positioning field and an actuator coupled with the support (2) and with the laboratory and medical device. The actuator includes a positioning element arranged on the support (2) for rotation or pivoting and having a rotation or pivot axis. For generating a restoring torque acting on the actuator, a bar-shaped or helical spring (6) is provided, which divergent from its helical axis is subjected to both torsion and bending, with the spring extending between the support (2) and the rotatable or pivotable actuator and eliminating or at least reducing the play of the actuator when the medical-technical device is positioned.

Abstract: A circuit arrangement (1) for generating motor characteristic curves, in particular for stabilizing the pull-out torque of a two-phase synchronous motor (2) by using a series-connected element (14). The series-connected element (14) is connected between a first line conductor (12.1) formed as a neutral conductor and the common phase (11) of the synchronous motor (2), and a second line conductor (12.2) implemented as a conductor is connected with a phase of the synchronous motor (2).
