An ergonomic fish tape configured to house a fish tape in accordance with some example embodiments is provided. The fish tape includes a shell having an upper base wall, a lower base wall, an inner side wall extending between inner perimeters of the base walls and forming a central aperture through the shell, an outer side wall extending between outer perimeters of the base walls and defining an outer diameter of the shell, the walls defining a cavity therein, and a storage tray within the cavity. An opening through which the fish tape can pass is provided through the outer side wall. The fish tape case does not include a handle, and the walls of the shell are devoid of surfaces which would indicate or suggest to a user as to how to grip the fish tape case.

A log handling device, having a rotatable rotor provided with log handler, and a feeder attached to the rotor for conducting an operating medium to the log handler. The feeder is arranged to wind around the rotor when the rotor is rotated in a first direction, and which feeder is arranged to unwind from around the rotor when the rotor is rotated in a second direction. The log handling device includes a rotatable second rotor to which the feeder is attached, and an operating device for rotating the second rotor synchronously with the rotor, such that the feeder is arranged to wind around the second rotor when the rotor is rotated in the second direction, and that the feeder is arranged to unwind from around the second rotor when the rotor is rotated in the first direction.

A system for electric power production from wind includes a glider having an airfoil, an on-board steering unit, a flight controller for controlling the steering unit, and a connection unit for a tether. The system further includes a ground station including a reel for the tether, a rotating electrical machine connected to the reel, and a ground station controller for controlling the reel and the rotating electrical machine. A master controller operates the system in at least first and second operation modes. In the first operation mode electric power is produced with the rotating electrical machine from rotation of the reel caused by reeling out the tether using a lift force generated upon exposure of the airfoil of the airborne glider to wind. In the second operation mode, the reel is driven by the rotating electrical machine, thereby reeling in the tether onto the reel.

The invention relates to a winding device (10) for a line (1), such as a cable or hose, including a stationary frame (11) and a winding drum (12), which is rotatably mounted on said frame and has an interior (12B). From the outside (12A) of the winding drum (12), the line can be wound or unwound. An inner rotary guide (18) in the interior (12B) guides the line (1) continuously from a fixed point (F) fixed with respect to the frame to a rotation point (R) on the winding drum (12) and defines a line course, having two opposite windings (18A, 18B) about the axis of rotation (A), and a rotatable deflection element (18C), in which the line changes over. According to the invention, the winding drum (12) has a first cut-out (15A) at a first end, on the side of the rotation point (R), which cut-out opens out axially and at an end face, and a retaining part (19B) at the other end, which retaining part is rotationally fixed to the frame, has a second cut-out (15B), which opens outward in a plane perpendicular to the axis of rotation (A). By virtue of the cut-outs (15A, 15B) in combination with the special rotary guide (18), the line (1) to be wound can be continuously routed without interruption and without rotational coupling or be subsequently attached, from the outside (12A) through the first cut-out (15A), in the inner rotary guide (18) and from the fixed point (F) of the rotary guide through the second cut-out (15B) or vice versa.
