The partition (3) has an opening (32) which is closed with an elastic rubber wall (4). The partition (3) is provided with a throttle passageway (31) which intercommunicates with both the main liquid chamber (A) and the auxiliary liquid chamber (B). The elastic rubber wall (4) has a flat surface (4a) facing the main liquid chamber (A), and a concavely curved surface (4b) facing the auxiliary liquid chamber (B) so as to have an arch-shaped cross-section. An inner periphery of the partition (3), which an outer periphery of the elastic rubber walls (4) contacts, has an inclined surface so that the diameter of the opening (32) of the partition decreases from the side of the main liquid chamber toward the auxiliary liquid chamber.

Abstract: A wire drawing machine having a watching system of the wire (9) diameter at one or more watched locations in the machine. The diameter is measured by measuring the wire speed as compared to the reference wire speed at a reference location where the diameter is accurately known and held in a register (3). This value, together with both speed values, are sent to a computer module (6) for calculating the wire diameter and sending this to the output (29,30). When a new wire enters in the drawing machine, the operation is temporarily inversed : the lastly computed diameter is temporarily taken as the reference diameter and stored in the register (3), and from there the new reference diameter at the entrance is calculated and entered in the register (3).

Abstract: A self-inking stamp with inking in an upside-down position consists of a lower part (1) which is to be placed on the surface to be stamped and which receives an ink pad (3), and also of, movable to and fro between the ink pad (3) and the set-down surface (2) with simultaneous turning, a stamp insert (4) which supports a printing plate or the like, and of an actuating part (5). The actuating part (5) engages around the lower part (1) with two side legs (5a) guided on its narrow side walls and is displaceable towards the set-down surface (2) against spring force. The turning pivot (7a) of the stamp insert (4) is mounted in the ends of the side legs (5a). This turning pivot (7; 7a) passes through the narrow side walls of the lower part (1) in straight slots. In the lower part (1), there are arranged in the region of its narrow side walls a fixed roll-off stop (9) and on the stamp insert (4), at a distance from its pivot (7; 7a), in the narrow side centre a gear member (12). The gear member (12) interacts, during the to and fro movement of the stamp insert (4), with the roll-off stop (9) in the manner of a rack and pinion gear. In order to achieve simplification of manufacture and to ensure that the stamp insert (4) after turning in each case maintains the correct position, the gear members (12) on the stamp insert (4) are of flat U-shaped design with leg ends which are rounded off or bevelled on the inside. In each case, there is provided as roll-off stop a single pin (9) which is exposed on the ink pad and set-down surface side. Adjacent to the cutouts (10) for this exposure are straight guides (11), which are parallel to the slots (8), for the leg ends of the gear member (12). <IMAGE>
