Abstract: A self-propelling combine and a method for operating a self-propelling combine are disclosed. The combine includes an axial spreader, which generates a residual flow of material and supplies the residual flow of material to a downstream distribution device that discharges the residual flow of material from the combine. The axial separator in the end-side material delivery region has at least one guide element that may be moved by an actuator, thereby affecting a distribution of the exiting residual flow of material over the supply width of the distribution device. The distribution of the residual flow of material is detected by at least one sensor unit, and when a deviation from a target distribution is detected, the guide element is adjusted. A control device receives and uses a signal representing a side wind used to automatically adjust of the at least one guide element.

Abstract: The lamp socket according to the invention demonstrates a housing (2) with a rotor (26). Contacts (15, 16), which demonstrate contact tags (17) that are resilient in the swivel direction, are mounted in the housing (2). The open ends (18) of the contact tags can support themselves on stopping means (31 to 34), which are moved by the rotor (26). In the support position, they are positioned on the ends (18) of the contacts (15, 16). When the lamp is rotated from its insertion position into its connected position, the support means (31 to 34) are distant from the ends (18) of the contacts (15, 16), however, so that the lamp can be rotated relatively freely without current. Only near the end of this rotational movement do cams provided on the support means (31 to 34) bump against the ends (18) of the contacts (15, 16) and force them radially inwards and clamp the contacts (15, 16) against the pins (45, 46) of the lamp.

Abstract: The invention relates to a needle covering device of an injection device, the injection device including a casing comprising a reservoir, in particular an ampoule, for a product fluid to be administered, and an injection needle for injecting the product fluid from the reservoir, wherein the device surrounds the injection needle in an extended position and exposes the injection needle in a retracted position. The device comprises a passage for the injection needle, a front section via which the device is placed on an injection point, and another section which is nearer to the casing than the front section is, at least in the extended position. The sections can be moved axially relative to the casing and relative to each other, such that the device is variable in its length, the front section being guided in a straight line on the casing.

Abstract: A signal light including a housing is recessed into a traffic surface and projects minimally upwardly from the surface and wherein a light processing assembly is provided to receive light from a light source, intensify the light and direct the light toward a light outlet in a generally linear manner, the arrangement for processing light being mounted to the housing. For this purpose, the light source is designed in such a way that it sends an essentially linearly directed light beam onto the light processing assembly. The light is collected in the light processing assembly in such a way that, when it exits, it is still linearly extending in at least one direction but it has a higher intensity. For this purpose, the light processing assembly includes a cylindrical-convex lens entry surface and a cylindrical concave mirror surface for receiving and directing light.
