A clutch mechanism for a mechanical effector device includes a reel configured for winding and unwinding a tendon around the reel, and a base configured to connect to and rotate with a motor for rotation of the base around an axis. The reel and base are further configured for alignment with and rotation around a common axis of rotation. Inner ends of the reel and base mutually castellated and interlocking and the castellations are configured to ride up and over one another to allow independent rotation of the reel and base if an unresolvable rotation force is encountered.

A method for controlling a display on a spinning machine or winder having a plurality of same-kind workstations and a plurality of displays includes assigning one of the displays to at least two of the workstations, wherein each display includes a display area. During normal operation of the workstations, information regarding the individual workstations assigned to the particular display is simultaneously displayed in respective subareas of the display area. When required by changed operating states at the work stations, a surface area of the subareas is changed to display information regarding at least one of the workstations on a larger subarea. An associated spinning machine or winder is also provided.

A device and a method for detecting a distance from a balloon to an ingot tank is provided. The device comprises a set of photoelectric transmitting tube and photoelectric receiving tube which are arranged in a height range of a balloon, Wherein a light beam between the photoelectric transmitting tube and the photoelectric receiving tube is arranged to be tangent to an appropriate balloon, and is used for detecting whether the balloon is located at an appropriate position according to a number of pulses received by the photoelectric receiving tube in one period of rotation of the balloon.

A fish tape tool includes a housing including a base and a cover. The housing defines a chamber between the base and the cover. The base defines an exit opening and a channel extending from the chamber to the exit opening. The fish tape tool also includes a drum configured to be inserted into the chamber of the housing, the drum containing a fish tape. The drum is configured to be manually rotatable relative to the housing to dispense or retract the fish tape from the housing via the channel and the exit opening. The cover defines a central aperture that is aligned with a central bore of the drum.
