Abstract: The invention relates to a device (1) for fixing a flexible element (10), particularly in the form of an artificial or natural ligament or a tendon, to a bone (20), comprising: an insert (100) being designed to hold said flexible element (10), and an anchor (200), wherein the insert (100) is designed to be inserted into said anchor (200), and wherein the anchor (200) is designed to be inserted into a bore hole (2) of said bone (20) together with said insert (100) inserted into the anchor (200) to fix the flexible element (10) to the bone (20).

Abstract: In a working method for a cleaning device (2) that moves back and forth in a swimming pool (1), control thereof is such that the cleaning device (2) moves from a starting position at a low speed in a forward direction V in a first pass in a first cleaning path (4) until it runs up to a pool wall (3), wherein the distance D1 traversed along the first cleaning path is measured or determined. The cleaning device (2) is then guided to a second cleaning path (5) deviating from or offset relative to the first cleaning path (4) in a second pass, initially at a low speed, whereupon the cleaning device then moves in a backward direction along the second cleaning path (5) at a high speed until the distance Dz traversed is smaller than the distance D1 traversed in the previous pass by an amount A.

Abstract: Cleaning device, especially for the cleaning of swimming pools, having a housing (1) and having at least one intake aperture (3) arranged on the base (2) of the housing through which, by means of a pump (4, 4′), a liquid to be cleaned can be conveyed into an inner chamber (5) at least partially enclosed by the housing (1) by a filter (6) which can be arranged in this inner chamber, in order to separate a contamination-exposed part (5′) from a clean part (5″) of the inner chamber, and through an outlet aperture (7), which is characterized in that the filter (6) lies sealingly on the bottom surface (8) of the inner chamber (5) and an underside (9) of a cover (10) which can be arranged over the inner chamber.

Abstract: A cleaning device (2) which can be moved backwards and forwards in a swimming pool (1) has a drive mechanism which can be switched to forward or backward travel and has one motor for a left-hand-side and one for a right-hand-side part of the drive mechanism and a control apparatus for controlling the drive mechanism. The control apparatus has a speed regulation apparatus for each part of the drive mechanism and has means for differentially controlling the speed of the two motors. The cleaning device has means on both parts of the drive mechanism for measuring the distances (d1, d2) covered in forward and backward travel. The angles (R1, R2) of change of direction are calculated and differentially controlled by the control apparatus on the basis of the measured distances (d1, d2) covered and an offset width (v) of the respective travel tracks.
