Abstract: A strap changeable between a first and second modes. In the first mode, the strap is movable, and, in the second, the strap is locked. The strap includes a mount removably attaching the strap to a camera. The mount includes a first strap portion that includes a first plurality of strap elements, each including a hole. The first strap portion further includes a first line connected to the mount and extending through the hole of each strap element of the first plurality such that the first plurality are arranged adjacent to each other along the first line. The mount includes a line tightening mechanism to tighten the first line to change the strap from the first mode to the second. The first plurality of strap elements, in the first mode, are movable, and, in the second, the first plurality of strap elements are locked.

Abstract: The invention relates to a system and method for separating pieces having a second density (9c) from granular material. The system includes a separation tank (2) comprising a first side wall (12) provided with a tank outlet (6), a bottom (7), a pipe (4) defining a channel (3a) for allowing a slurry to enter the tank (2). A pipe outlet (4b) is spaced apart from the tank outlet and arranged vertically below the outlet (6). The separation tank (2) comprises a trap (5) for collecting said pieces. A separation chamber (8a) is arranged in liquid communication with the pipe outlet to allow slurry to enter the separation chamber. The pipe outlet is in a lower third of the separation tank facing the bottom of the tank so that slurry flows vertically through the pipe outlet towards the bottom causing a turbulent flow of the slurry in the tank.
