Abstract: A dispensing pump (1) made of plastic for dispensing metered amounts of paste-like media includes a bottle-, can- or tube-like container (60), with an elastic bellows (4) acting as a pumping member, which is connectingly arranged between an upper housing part (2) and a telescopingly movable, lower housing part (3), which is coaxial thereto, and whose interior (32) forms a pump chamber. Its upper end section (38) is connected to an annular wall (35) of the upper housing part (2). Its lower end section (45) is in sealing contact with an annular shoulder (46) of a radial partition (19) of the lower housing part (3).

Abstract: The dispensing pump for dispensing metered amounts of paste-like or liquid substances from paste containers (41) is provided with a bellows (3) acting as a pumping member, which bellows are sealing arranged between two coaxial housing parts (1, 2), which are made of a dimensionally stable plastic and are telescopingly movable relative to one another. Suction and discharge valves (4, 5), designed as one-way valves with axially movable valve closing members (19, 32), are arranged at its two ends. A suction pipe socket (29), which is concentric to the suction valve and is directed toward the paste container (41), is located at a suction-side radial wall (12) of one /f the housing parts (2).

Abstract: The metering pump dispenser serves for simultaneous metered output of liquid and/or pasty media from at least two separate supply chambers (18, 19), which are arranged in a common pump housing (2) and to which are assigned individual separate metering pumps (5, 6), each with an intake and output valve (23, 24). The metering pumps are manually driven by a common actuating device (3), which extends on the side of actuation in a common front side of the metering pumps (5, 6) that are present and is provided with one or more output channels (57, 58). Metering pumps (5, 6) each have as pump devices communication bellows (21, 22) which are joined on the housing side with pump housing (2) and on the output side with the common actuating device (3). Actuating device (3) is a lever-type device mounted in a swiveling manner around a swivel seat (11) on one side in a head part (10) of pump housing (2) axially projecting over supply containers (18, 19), for conducting limited pump strokes.

Abstract: The exposure head of a repeating copying machine is disposed on a slide, with the exposure head being able to be traversed on a table of the copying machine by means of the slide and having a master carriage, an exit carriage and feed means, with a magazine having individual compartments for masters being attached at that end of the slide that is adjacent to the master carriage. The magazine and the feed means are mutually adjustable one relative to the other in both the vertical and horizontal planes, thereby permitting the feed means to be brought into engagement with any of the masters contained in the individual compartments of the magazine for the purpose of removing the master from the magazine and transferring it to the master carriage.
