Abstract: An apparatus for the intermittent application of a liquid to pasty medium onto an application surface, comprising an application valve which can be switched between an open and a closed state and is intended for dispensing the medium onto the application surface, a volumetric delivery pump for metering a volume of the medium to be passed on to the application valve, and a drive for operating the volumetric delivery pump is, inter alia, described and illustrated. The characteristic feature consists in that the apparatus has an electronic controller which, in each case cyclically, activates the drive and the application valve in dependence on each other.

Abstract: Typing ribbon cartridge for typewriting and/or printing machines in which a typing ribbon (2) has a section that runs freely outside the cartridge housing between two housing side-arms (4). To select one of several typing tracks this section is moved perpendicularly to the longitudinal axis of the ribbon section in such a way that equalization of the differing tensions of the ribbon edges in the various positions of the free section of the ribbon is obtained. For this purpose guide elements (9) are provided, which are mounted on guide edges of the side-arms (4), which are arranged perpendicular to the longitudinal axis throughout their entire length and in the ribbon plane, and the guide elements are tiltable about axes (15), which are arranged perpendicular to the plane of the free section of the ribbon and which intersect the guide edges.
