The invention relates to a drive for a driving rod (1) for a window or door, wherein a toothed wheel (7) which is, for example manually controlled by a hand lever, is rotationally mounted in a housing (4). A driving rod (3) movable along the housing (4) and directly or indirectly interacting with the teeth of the toothed wheel (7) is associated therewith. Abutments (13) extending in a parallel position to the axis of rotation (14) of the toothed wheel (7) are provided in the housing (4) for the hand lever fixing elements. Said housing (4) comprises two housing halves (5,6) in which the toothed wheel (7) bearing is placed. A spacer (8) is arranged between the housing halves (5,6) and comprises the abutments for the hand lever fixing elements and fixing elements connectable to said housing halves (5,6). The aim of said invention is to design a drive for the driving rod drive consisting of individual parts which are easily producible at low cost and mountable without any problem. For this purpose, the housing halves consist of identical plates (5, 6), the spacer (8) is embodied in the form of an angled metal sheet section which is placed between said plates and comprises at least one vertical web (15) which extends along the axis of rotation (14) of the toothed wheel (7) and is associated with said plates (5, 6) for fixing, the spacer (8) length approximately corresponds to the space between the fixing elements, and the abutments (13) are mounted on said spacer.

The device (1) comprises a base (2), carrying a servo motor (3) and attached to the frame of a machine center. A carriage (6) with a vertical shaft (8) on top can be moved on two telescopically arranged rails (4,5) joined horizontally to the base (2). The tool holding elements (16,17) are positioned at the upper end of the shaft (8) and can be fixed with a locking unit (18). A control plate (12) is located at the second rail (5) acting in combination with a guiding roll (10) in order to facilitate a swivel motion of the tool carrier (15).

An electromotive variable-speed and control drive particularly for use in industrial sewing machines and comprising a coupling coil casing radially surrounding a coupling-brake disk and a brake coil casing radially relocated towards the center. Both are positioned in the brake end shield. In order to avoid a sticking of the coupling-brake disk with high alternations and a delay of the break-down and build-up of the magnetic fields, a brake coil casing has been relocated radially so near to the center that it is situated within the brake pad in front of the armature ring. On the other hand, there is an undercut and a recess at the coupling coil casing and a recess at the disk flywheel which assures that no axial forces can occur at the radial gaps.

The invention relates to a gearbox control device comprising an input clutch which is controlled by a clutch release fork (30) and at least two shift actuators (200, 100) which each control two forward gear shifts. The invention is characterised in that the clutch release fork control shaft (50) can be moved by one of the aforementioned actuators.

The device for producing microstructures has a rotating driven spindle (12) and a holder for clamping a workpiece (16). A fast drive is coupled to a tool (32) over a guidance arrangement, which permits adjustment of the tool in an axial direction of the fast drive against a return force. The drive has high rigidity in the plane perpendicular to the drive direction. An independent claim is made for an actuator (30) for moving the tool of a turning machine (10) to produce a micro-structured surface in a workpiece, especially using a piezoelectric drive.

The invention relates to an escalator or moving walkway that includes a drive shaft rotating at a relatively low peripheral speed around a horizontal axis and at least one sealing element associated with the drive shaft. Lubricant is supplied to the drive shaft and can escape from leakages at the one sealing element. A device is provided for a permanent recirculation of the lubricant escaping from the leakages. The device includes at least one conveyor element arranged downstream of the sealing element, seen in the direction of the leakage, and at least one recirculation element for the lubricant. The recirculation element cooperates with the conveyor element to return the lubricant into a region upstream of the at least one sealing element.

The device has a base plate (2) with socket for holding a side wall (4) and fixing means for rollers (5, 6) mounted on assembly plates (20). The socket has a further preferably iron plate (3) which is mounted fixed with the assembly plate on the base plate. The iron plate, assembly plate and base plate can have corresponding holes and grooves for screw fixing.

The device has two parts (12,14) that can be plugged together and that can be coupled by a sliding element (16) fed into one connector part, especially transversely to the plugging direction, and a securing element (24) movable between a starting position and an end position in which it fixes the sliding part in its end position. The securing element is locked in its starting position and is only released for movement to its end position with the connector parts coupled.

A power transmitting apparatus comprises a housing (3) having an opening at its end surface in the longitudinal direction thereof to be closed by a cover member (33), which supports an end of a brake support shaft (60) rotatably supporting a brake shoe (61). A hydraulic cylinder (63) for operation the brake shoe (61) is detachably attached to a side wall of the housing (3). A piston (64) of the hydraulic cylinder (63) contacts with a free end of the brake shoe (61). The cover member (33) also supports ends of a clutch shaft (26) and a PTO shaft (29), while a clutch housing (38) of a PTO clutch (27) is provided on the clutch shaft (26) so as to be braked by the brake shoe (61) in the state of the PTO clutch disengaged, thereby constituting a subassembly. By attaching the cover member (33) to the end surface of the housing (3) so as to close the opening, all the brake support shaft (60), the clutch shaft (26) and the PTO shaft (29) supported by the cover member (33) are installed in the housing (3).
