Abstract: The invention relates to a device for improving the transmission properties of a bundle of electrical data lines, particularly of a bundle of copper twin wires, and to a system for transmitting data that is provided with a device of this type. Said device comprises at least one adaptive filter, which generates an output signal for correcting the signal transmitted on a first data line. At least one signal tapped by a second data line or an external signal is used as a reference signal for the adaptive filter, and the corrected signal transmitted on the first data line is used as an error signal for the adaptive filter. According to the invention, the device is situated in the transmission path whereby improving the transmission properties of the cable independent from the switched-on transmission units and employed transmission techniques, particularly in the event of high bit rate transmission.

Abstract: The invention relates to a sealing element (1) with inflatable bellows (10) for sealing piping. Said sealing element can be e.g. cylindrical in shape and said bellows (10) can be provided with two recesses (14a, 14b) containing a gel (11). When the bellows are inflated, the gel (11) encompasses e.g. uneven areas on the inner wall of the piper or cables in the pipe in such a way as to provide a seal.

Abstract: A device to accommodate simple and efficient insertion of elongate articles, such as wires, cables or pipes, into clamps adjacent one another inside an inaccessible tube. A setting head having at least two parallel and adjacent receiving grooves receive the elongate articles and a guide means is adjustable to accommodate various sized tables.

Abstract: The present invention relates to a tightening fastener, in which a clip band is bent in the shape of a ring or a spiral, as well as a tension locking system, wherein the clip band can be used to fasten elongated objects such as cables or pipes in pipeworks and mainly pipes which cannot be accessed. A series of radially protruding holders may be attached to the clip band. These holders are positioned to receive cables, pipes, or other elongated objects. The tension locking system may include a stop member which can, for example, be made in the shape of a stop bolt and which may be maintained in a stop position by a stop frame. When the stop bolt is disengaged from its stop position, the tension locking system partially expands and transmits the tightening force to the clip band, thus tightening the clip band.
