Abstract: A portable urination weight measurement device comprising: a holding unit for releasably holding a container, and a handle comprising a weight measurement unit coupled to the holding unit so as to allow the measure of a weight exerted on the holding unit; and a toilet flushable container having: a rim having a fold at a front side of the opening and a fold at a back side of the opening, each fold forming at rest an angle of less than 20°, and a collar secured to the rim and comprising at least one fold at the front side of the opening forming at rest an angle of less than 20°, the collar being of a rigidity such that increasing the angle of the collar fold to 180° increases the angle of the rim fold at the back of the opening to from 50 to 90°.

Abstract: A chuck for a machine tool having a rotation spindle with a main axis of rotation. The chuck comprises a base plate, a first rotatable plate eccentrically mounted on the base plate, a second rotatable plate eccentrically mounted on the first rotatable plate, balancing means for aligning a principal axis of inertia of the chuck with the main axis of rotation and a holding mechanism. The chuck is provided with an actuating mechanism for angularly displacing the first rotatable plate around a first rotation axis over a first angle of rotation and/or the second rotatable plate around a second rotation axis over a second angle of rotation such that the position of the object with respect to the main axis of rotation can be altered.
