A fish tape tool includes a housing and a chamber defined in the housing. A drum is configured to be inserted into the chamber of the housing. The drum contains a fish tape. The drum is rotatable relative to the housing to dispense or retract the fish tape from the housing. The drum is one of a plurality of drums that are insertable into and removable from the chamber of the housing. Each drum contains a different type of fish tape.

A twine tension relief assembly for a baler including a tension detection apparatus for detecting the tension in a line of twine, a biased cutting element displaceable between a first retained position and a second released position and an actuator adapted to cause the biased cutting element to move from the first retained position to the second released position in response to a signal issued by the tension detection apparatus. The practical application includes when the tension in a strand of twine exceeds a predetermined threshold, the tension detection apparatus causes movement of the biased cutting element so that a strand of twine passing though the twine tension relief assembly is severed and damage to the knotter mechanism and its component parts is avoided.

A method for operating a work station of a textile machine that produces or rewinds yarn in a normal operation, wherein the normal operation is interrupted. The method includes performing at least one service step for restoring the normal operation, wherein a service result is specified for the service step. A standard service operation is carried out with a service device until the service result has been achieved or a predetermined number of failed attempts has been reached. When the predetermined number of failed standard service operation attempts has been reached, an extended service operation is carried out.

A baler twine tension control assembly including a displacement detector and elements defining a twine path. The twine path enters and exits the twine tension control assembly and within the twine tension control assembly extends across a first fixed location and a second fixed location as well as across an intermediate displaceable location located between the first fixed location and the second fixed location. The displacement detector is connected to the intermediate displaceable location and generates a signal indicative of the displacement of the displaceable location.

A baler twine tension measurement assembly including a displacement detector and elements defining a first twine path. The first twine path extends between a first location and a second location which is angularly displaceable with respect to the first location. The displacement detector operates to generate a signal indicative of the angular displacement of the second location with respect to the first location.

A guiding chain carrier system (1) is configured for an installation (2), for deploying and for storing without folding said guiding chain and flexible supply cables and/or pipelines. Said guiding chain carrier system comprises a mobile workstation (6) movable over a work surface (3) and connected to the said cables and/or pipelines, at least one guiding chain (20), connected to a static connection area (7) on one end and to the mobile workstation (6) on the other end thereof, for supporting said cables and/or pipelines; characterized by at least one compensation trolley (8), comprising a compensation system. Said compensation trolley (8) is movable and the compensation system is able to generate a resistance force in order to maintain the guiding chain (20) straight while the mobile workstation (6) moves from an operation location nearest the static connection area (7) until an operation location furthest from the static connection area (7).

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.
