Abstract: A tool for marking livestock is a cylinder of marking material enveloped by a sheathing. The sheathing is segmented annularly at intervals along the vertical axis and each segment and is cut vertically so that it can be removed in sections to gradually reveal more of the marker.

Abstract: A one-way drive strap wrench having two strand parts (11A, 11B) and a shoe (15) for bearing against an oil filter (2). The shoe is pivotally mounted about a laterally offset axis (16). The wrench is particularly adapted for the fitting and removal of motor vehicle oil filters.

Abstract: A one-way drive rotor (3) is accommodated in a bore (4) of a driving part (1) of a tool and is held, on the one hand, by a shoulder (14) integral with the rotor and, on the other hand, by an annular component (7) on which the head (34) of a central screw (13) screwed into the rotor bears. The extent to which this screw is tightened defines the axial play of the rotor. The screw is hollow and has a push rod (9) passing through it which allows a ball (6) to be locked or released, this ball positively retaining a rotary member such as a drive socket, which is fitted onto the end fitting (5) which extends the rotor.
