Abstract: A developer station is provided for electrophotographic printer and copier devices, including a developer conveyor means (3) and a developer deflection housing. The developer deflection housing, on whose outside surface developer material is conveyed, has a developer transfer area (2a), at which developer (7) conveyed in by the conveyor means (3) is applied onto the developer deflection housing, and a toner transfer area (2b), which transfers toner to a photoconductor, applied on its surface, the toner transfer area (2b) proceedings complementary to the surface of the photoconductor (4). Further, a magnet rotor (1) is arranged such in the deflection housing that the spacing thereof from the surface of the deflection housing decreases at least up to the toner transfer area (2b) proceeding from the developer transfer area (2a).

Abstract: A housing for a magnetic disk memory comprises a support shell and a cover for housing a magnetic disk pack and a rotational positioner. The disk pack is provided with two bearing locations one of which is secured to one lateral wall of the support shell and the other of which is defined by a slot open toward the edge of the supporting shell in an opposite lateral wall for receiving a disk pack bearing bushing. A seal is provided between the support shell and the cover for a dust-free seal of the interior of the housing, the seal being a closed sealing ring which is pinched at the parting plane between the support shell and the cover. The seal comprises a perpendicularly projecting semi-circular extension in the region of the slot--which encompasses the bearing bushing and is fixed to the exterior of the lateral wall in a recess formed therein.
