    摘要: Actuator (1) adapted to be actuated by pressurized fluid as shown for example in FIG. 3, having a plurality of piston-cylinder units (A, B, C, D, E, F) arranged one behind the other and displaceable in the direction of a longitudinal axis (9), in which adjacent parts such as a piston of one unit and a cylinder of the adjacent unit are combined to form a connecting part. The individual piston-cylinder units (A, B, C, D, E, F) are so dimensioned in their lengths that the piston-cylinder units can be provided with different respective stroke lengths (ha, hb, hc, hd, he, hf). The stroke lengths can be varied by devices such as screws with hexagonal sockets (26, 110, 111, 113), and adjusted by a screw-turning tool (34). The actuator (1) has a small number of inexpensive individual parts and is easy to manufacture.

    摘要: A sewing machine (1) with an overload clutch in the form of a friction clutch in the region of the handwheel (44), with a positioning motor (57), including a motor part (56) and a control part (55), and with a position transmitter (51) connected to the arm shaft (5). In the event of a blockage of the arm shaft (5), the control part (56) causes the positioning motor (57) to stop immediately and a fault warning to be output on an indicator panel (68) of the control apparatus (66). After the fault has been eliminated and the power supply has subsequently switched off and switched on again, the sewing machine (1) is ready for operation again.

    摘要: A sewing machine with a hook (8) that is drivable in rotation about a vertical axis comprises a bobbin case (21) with a lifter cam (31). A case lifter (33) is provided, having a sensing lever (40) and a lifter lever (32) that bears against a lifter cam (28). The sensing lever rests on a cam face (42) of an axial cam disk (39) which is mounted on the transmission shaft that actuates a hook-driving shaft (10).
