Abstract: According to an example a dampening system for a hinged component may include a spring having a first end hooked onto a chassis and a second end hooked onto to a strap, in which the strap is connected to the hinged component. The dampening system may also include a curved guide element attached to the chassis, in which the spring is to bend around a portion of the curved guide element as the strap is moved from a first position to a second position.

Abstract: Protruding exposed edges of the foil carrier of an electrode in a jelly roll cell are specially indented inwardly at intervals to facilitate placement of an insulator ring at the top of the cell after insertion of the electrode in the container. Effective insulation of the exposed carrier edges from the container wall and good continuity of contact to the pressure contact means are achieved by the radial indenting of the axial ends of the exposed foil edges toward the axial center at intervals on at least a significant number of the outer turns of the foil coil to form sloped vallues and intermediate sloped ridges between said valleys, said outermost turns of the foil edges being pushed together at said valleys and spaced at said ridges.
