Abstract: An electrical pressure contact device includes a sleeve with a first end and a second end. A contact head is slideably mounted in the sleeve and has a first end protruding from the sleeve and a second end located in the sleeve. A connecting piece has an inner portion connected to an inner wall of the sleeve and an outer portion protruding from the second end of the sleeve. An axially extending bore in a first piece located in the sleeve receives an elongated member of a second piece. A band has a plurality of inwardly arching lamellae and is located in the bore. The elongated member is inserted in the band so that the lamellae rub against the elongated member. A biasing element in the sleeve surrounds the elongated member and urges the contact head away from the sleeve.

Abstract: A reinforced concrete ceiling is characterized by a combination of the following features: a concrete slab (1) the thickness (D) of which falls short of the total thickness of the reinforced concrete ceiling, and intersecting ribs (2) which are each connected with an end region (3) to the concrete slab (1) in a force-transmitting manner and project freely upwards from the concrete slab (1), i.e., without being integrated in a further supporting surface structure, wherein their top end regions (4) are designed to absorb compressive and/or tensile forces and wherein the ribs (2) are connected to each other in a frictional manner at the respective intersection points (9), and their regions lying in each case between the top and bottom end regions (3,4) have at least one aperture (6).

Abstract: The invention relates to an electrical pressure contact comprising a housing sleeve (10) that is provided with an end facing the contact and an end facing away from the contact, a conductive contact head (14) which is mounted in the housing sleeve (10) so as to be movable in an axial direction while protruding from the end of the housing sleeve (10) facing the contact, a biasing element (42) which is disposed in the housing sleeve (10), the contact head (14) being inserted into the housing sleeve (10) counter to the biasing force of said biasing element (42), and a conductive connecting piece (30) that is used for fastening an electrical feeder and is located at the end of the housing sleeve (10) facing away from the contact.

Abstract: The invention relates to a fluid-tight, in particular oil-tight, cable duct (10) with a duct body (12), includes an inner side (16), exposed to a fluid, an external side (18) separated from the fluid and at least one cable channel (20), through which at least one electrical line (14) formed by a flex is run from the inner side (16) to the outer side (18) of the duct body (12). A seal element (22) is arranged in the cable channel (20) with a number of individual channels (32) passing therethrough which corresponds to the number of lines and through which the lines (14) run individually. The lines (14) are each formed from two line sections, connected by an electrically-conducting connector piece (50) with a solid cross-section, whereby the connector piece (50) is housed within the single channel of the sealing element (22), at least over a part of the length thereof.
