Abstract: A plunger-operated dispensing device for liquids includes a stock container for a liquid, at least one vertical dispensing cylinder with a dispensing plunger therein which can be moved in the axial direction of the dispensing cylinder between two end positions. The lower end of the cylinder is in communication with the stock container via a channel having a movable shut-off valve therein. The outside diameter of the dispensing plunger is smaller than the inside diameter of the dispensing cylinder is that a certain space is present between the wall of the cylinder and the plunger. Near its lower end the dispensing plunger is provided with a sealing ring for sealing the space between the cylinder wall and the plunger. The movement stroke of the dispensing plunger can be displaced in the direction of the lower end of the dispensing cylinder, such that, in the lower end position of the plunger, the sealing ring of the plunger reaches past the lower end of the dispensing cylinder.

Abstract: This invention concerns a connecting device for synchronously intercoupling machines mounted in series and handling a stream of objects 9 e.g. bottles which are uninterruptedly fed by a first machine 1 toward a second machine 4, the device essentially comprising a set of overlapping worms 6, 7 serving to arrange or classify the stream of objects, one of the worms 6, being positively retractable in a direction perpendicular to the direction of travel of the stream of objects, a guide rail 20 for the objects being provided at the location of the retractable worm 6.
