Abstract: A device for applying a reactive liquid, especially an adhesive, to an essentially level surface (3). The device comprises a liquid reservoir (4) and a plurality of outlet openings (8) for the liquid, which can be controlled and sealed by valves. The valves are formed by elastic, essentially tubular line segments (14), and the cross-sectional areas of the lines can be pinched off simultaneously by a clamping device (6). With the device the process safety and dependability in the application of reactive liquids, such as in the application of adhesive to the surface of panel materials, for example, can be improved significantly.

Abstract: The openpit mining device includes a cantilever arm which is swivellable around a horizontal axis and carries a support or tool carriage. The support or tool carriage is shiftably supported in a transverse relation to the longitudinal axis of the cantilever arm and has tools rotatably supported on it. For this purpose, the head of the cantilever arm carries a rod-type guide and the tool carriage or support carries a rod-type guide. The guide rods are mutually interconnected with interposition of an intermediate carrier. The shifting drive is provided by hydraulic cylinder-piston-aggregates which are arranged between the intermediate carrier and the head and between the intermediate carrier and the support.
