A guard tube assembly for a drive shaft of a power tool has a guard tube with a tube cross section deviating from a circular shape and having an inner contour and a center. An inner support tube inside the guard tube supports the drive shaft. The inner support tube has a bearing sleeve supported by support elements on the inner contour. The inner contour has a first and a second circumferential section. The first circumferential section has a smallest spacing to the center and the second circumferential section has a largest spacing to the center. The elastic support elements have a contact surface contacting the inner contour and spaced at a contact surface spacing to the center. The contact surface spacing is longer than the smallest spacing of the first circumferential section and shorter than or identical to the largest spacing of the second circumferential section.

A hydraulic actuator includes a tool unit (10) having a tool that operates by pressurized oil generated by a hydraulic pump (40), a driving unit (60) that generates a rotation torque, and a torque transmission coupler (70) to one end of which the tool unit (10) is detachably attachable and to other end of which the driving unit (60) is detachably attachable and that transmits the rotation torque generated by the driving unit (60) to a rotatable member (41) of the tool unit (10). The torque transmission coupler (70) includes a flexible rod-like shaft (74) and a flexible cover (72) that surrounds an outer peripheral surface of the shaft. The torque transmission coupler (70) is bendable as the shaft (74) and the cover (72) have flexibility.

A multi-appliance power unit (100) selectively driving one of a plurality of power driven appliances (114) from one relocatable power plant (102). The modular power plant (102) is entrapped on a platform (108) and is movable therealong to any one of the appliances (114) fastened to the platform (108), which appliance (114) can then be driven by the power plant (102). A modular power plant and power driven appliance kit (200) includes a wheeled chassis (204) having a handle (220), a removable modular power plant (202 or 212), and a removable modular power driven appliance (212 or 202). A flexible drive shaft (300), is optionally integrated with a power plant or a powered appliance. The flexible drive shaft (300) includes an outer flexible sheath (310), roller type bearings (308), and a multifilament torque conducting flexible core (306) held spaced apart from the outer flexible sheath (310) by the bearings (308).

The invention relates to a flexible catheter (1) with a drive shaft (2), with a sleeve (6) surrounding the drive shaft (2) and with a sheath (7) surrounding the drive shaft (2) and the sleeve (6), wherein the drive shaft, the sleeve (6) and the sheath (7) are pliable, wherein the drive shaft (2) at a proximal end of the drive shaft (2) comprises a coupling element (5) for connecting the drive shaft (2) to a drive motor (18), wherein the drive shaft (2) at least regionally consist of a alloy which contains at least 10% by weight of chromium, nickel and cobalt in each case. The invention moreover relates to a blood pump arrangement with such a catheter.

The figure system includes: a plurality of drive units each including an actuator that generates rotative force; and a figure including a plurality of movable mechanisms and a plurality of flexible wires. The movable mechanisms each include a movable body that operates by the rotative force and an operation amount detector that detects an amount of operation of the movable body. The flexible wires include their respective first ends that are coupled to the movable bodies. The rotative force generated by one of the actuators is transmitted to corresponding one of the movable bodies through one of the flexible wires.

A table saw includes a table assembly having a top surface, a cutting assembly, and an adjustment assembly. The cutting assembly is arranged below the table assembly and is movable relative to the top surface. The adjustment assembly is operably connected to the cutting assembly and includes an input member, an output member, and a flexible shaft. The output member is operably connected to the cutting assembly and is configured such that rotation of the output member causes the cutting assembly to move relative to the table top surface. The flexible shaft has a nonlinear central axis, a first end operably connected to the input member, and a second end operably connected to the output member. The flexible shaft is configured such that rotation of the input member causes rotation of the first and second ends, and rotation of the second end causes rotation of the output member.
