The adjusting drive is controlled in dependence on the excess current of the motor and acts on either of the switching means in the conductor lines between the motor and current source to switch off the motor. A blocking arrangement is also used so as to prevent further movement of the motor after a shutdown which arrangement becomes unblocked upon reversing of the motor.

The present invention provides an improved adjusting shim used in a valve train for an internal combustion engine for an automobile. The adjusting shim produced from a base material consisting of a ceramic material containing 80 to 98 wt. % of silicon nitride and/or sialon and has a porosity of not more than 3%, a bending strength of not less than 1.0 GPa and an impact compressive elastic limit (Hugoniot elastic limit) of not less than 15 GPa, wherein the base material is provided on the surface...

An arrangement is provided for the adjusting of a mounting part on a carrier in a statically determined position which can be adjusted in a rotatory and translatory manner in three axes with respect to the carrier. The arrangement comprises at least three adjusting units which are arranged in an offset manner with respect to one another between the carrier and the mounted part, each of which comprises two connecting parts which can be translatorily adjusted relative to one another in two axes an...

An adjusting mechanism for adjusting the position of a first structural member relative to a second structural member. The mechanism is particularly well suited for use as a mechanism for adjusting the vertical or lateral position of a chair back or armrest relative to a chair seat and is adapted for one-handed adjustment. The adjustment mechanism has an arm mountable to a first structural member and slider securable to a second structural member that slidably engages the arm. A ratchet rack is ...

An adjusting drive comprises an electric motor having a motor armature provided with a motor armature shaft, a worm transmission associated with the drive motor and having a worm shaft which is formed as a floatingly arranged extension of the motor armature shaft, the worm shaft having a free end provided with a convex end surface, a stationary running element on which the motor armature shaft is fixed in an axial direction when it is rotated in a rotary direction, so that a pitch angle of the w...

An adjusting device for a throttle valve in a fuel preparation system of an internal combustion engine has an electric servomotor and a control device, which controls the servomotor as a function of engine operating parameters. For the sake of simple adjusting device structure, great sturdiness and a long service life, an asynchronous motor with a short-circuit rotor is used as the servo motor.

The invention relates to a method for controlling the draft of a fiber mixture (e.g. a sliver) of a textile machine, with sensors being provided which detect the fluctuations in mass of the fiber mixture which is supplied to a drafting arrangement unit including at least one changeable drafting zone which compensates the fluctuations in mass. A delay time is provided in order to take into account the running time of the fiber mixture from the measuring sensor up to a control application point. A...

A compact electric adjusting drive for locking systems, fan flaps or the like in motor vehicles includes a fluidic force transmission system between the electric motor and the adjusting element movable to and fro between two end positions.

An adjusting device for fastening an operating and/or display device on a wall, having a linear guide arrangement formed by a sliding element and a fastening element, wherein the sliding element has an attachment point for the operating and/or display device. A secure support of the operating/display element results if the fastening element or the sliding element has a pivotable seating arrangement or hinge, with a pivot axis oriented parallel with respect to the displacement direction of the li...

Two strap members are respectively connectable with a seat member and a backrest member and are joined for relative pivoting movement. An inner and a cooperating outer gear annulus are provided on the respective strap members in engagement with one another. A brake sleeve is provided on one of the strap members and a helical spring is located within the brake sleeve and normally frictionally engages an inner surface thereof. The spring has two inwardly angled end portions. An output member is tu...
