Abstract: A metal-powder and/or ceramic-powder press device includes at least one first punch (11) which, in a pressing position, is arranged to pass from a first side into a die opening, filled with ceramic and/or metal powder, of a die (13). At least one second punch (12), in the pressing position, is arranged to pass from a second side into the die opening, filled with ceramic and/or metal powder, of the die (13). A position measuring device determines a position of the first punch (11) and includes a first measuring element (16) and a second measuring element (19). The first measuring element (16) is connectable to the first punch (11) and the second measuring element (19) is connectable to the second punch (12), such that a relative position of the measuring elements to one another changes during the pressing operation. A sensor device determines the change in the relative position.

Abstract: A toothbrush has an integral identification system for distinguishing one (1) toothbrush from another. At the bottom of the toothbrush handle is a cylinder and rotating thumb wheel assembly. The cylinder has a plurality of indicia which are visible one (1) at a time through a window on the side of the brush handle. A user rotates the thumb wheel to display an individual indicium. Once selected, a locking pin mechanism prevents the cylinder from being accidentally turned. These features allow multiple users to distinguish their toothbrush from another's by verifying the displayed indicia. Alternative embodiments can be retrofit and/or replaced on a toothbrush handle.
