Abstract: A cartridge for an admixing arrangement of a manually operable arrangement for spraying a solvent, in particular water, into which an additive in the form of a liquid concentrate, such as a plant or crop protection agent, has been mixed, includes an outer cartridge housing; a pressure-sensitive inner container for accommodating the liquid concentrate; a mixing chamber, the mixing chamber having a device with a first outlet opening, for the concentrate or plant spray, an inlet opening, designed as a throttle, for the solvent or water, and a second outlet opening for the concentrate/solvent mixture.

Abstract: A method for fabricating a geometric beamsplitter involves applying a reflective coating having at least one metallic layer to a transparent substrate. A pattern of holes containing numerous holes that are preferably randomly distributed over its reflective surface is created in the reflective coating using laser processing. The method allows inexpensively fabricating beamsplitters that have accurately defined transmittances. Beamsplitters in accordance with the invention are suitable for use as dosimetry mirrors on, for example, the illumination systems of microlithographic projection exposure systems.

Abstract: In a sweeping apparatus with a sweeping roller arranged substantially horizontally to a sweeping surface and a storage bin for swept material fixable to the sweeping apparatus and which has a sweeping edge facing the sweeping roller, the sweeping edge is movable relative to the sweeping roller in such a way that the vertical position of the sweeping edge with respect to the sweeping surface is independent of the vertical position of the sweeping roller with respect to the sweeping surface.

Abstract: With a limited separating spacing immediately upstream of a mowing implement rotating in a horizontal plane, a lawnmower has an upward extraction implement rotating in the same direction as the advance direction about a horizontal transverse axis and which is located in a common casing, but in a separate casing chamber. The upward extraction implement is disengagingly driven by means of a gear by the drive motor of the mowing implement and is essentially located between the front wheels, which are vertically adjustable for the joint setting of the working height of the two implements. Thus, it is possible to in each case separately and also jointly and simultaneously work with the two implements, so that numerous use possibilities exist.

Abstract: A set of garden or household implements comprises various different garden tool and/or household implement heads and at least one handle which can be selectively attached to any of the heads by means of a quick-connect coupling. The coupling comprises a coupling sleeve on the handle and a coupling pin on each head. The pin and the sleeve are so configured that the pin cannot turn or tilt in the sleeve. Abutments on the pin and the sleeve limit the extent to which the pin can be pushed in. Removal of the head from the handle is prevented by a releasable locking member, which is provided on the sleeve and co-operates with the pin. The locking member can comprise a transverse screw or a sneck which engages in a peripheral groove in the pin or a transverse latch which can engage in a transverse bore in the coupling pin.
