Abstract: An electrically contacting fastening device has a threaded bolt and a nut, between which an electric contact element can be arranged. The threaded bolt has a contacting portion for creating planar contact with the contact element, and a threaded portion. The nut can be secured on the threaded bolt by way of the threaded portion and at an end face has a contacting area for creating planar contact with the contact element. The threaded portion of the threaded bolt is provided with a lubricant coating and the contacting portion of the threaded bolt, the contact element and the end-face contacting area of the nut are permanently free of lubricant.

Abstract: A system for retrieving information includes at least one database (120) storing a plurality of first content streams (50, 60, 70), each content stream (50, 60, 70) having at least one first search criterion assigned thereto. A content stream generating unit (101) for receiving a request to generate at least one second content stream (50, 60, 70), the request including at least one second search criterion. A comparing unit (102) for comparing the second search criterion to the plurality of first search criteria, an identifying unit (103) for identifying at least one first search criterion matching the second search criterion, and a subscribing unit (104) for subscribing the second content stream (50, 60, 70) to the first content stream (50, 60, 70) assigned to the matching first search criterion.
