Abstract: In a method of securing piling locks in order to transmit thrust, an adhesive is applied between the surfaces of the interlocking halves (1 & 5) of the lock that come into contact with each other in the inside (4) of the lock.
Abstract: To extend the temperature range of composite materials the composite material is made up of more than two hard layers which are joined with thin intermediate layers of viscoelastic material where one intermediate layer differs from another intermediate layer in that its softening range lies in a different temperature range so that the damping ranges of the intermediate layers also are different.

Abstract: In the method and the apparatus for measuring and controlling the roll gap in a roll stand the roll gap is illuminated by a light source transversely of the roll axis or also parallel to the roll axis. A camera, in particular a CCD line camera, is aligned with its optical system with the roll gap and the illuminated part of the gap is broken down in this camera in the direction of the height or thickness of the gap into image points which generate on illumination an electrical charge, the image points being consecutively periodically interrogated for bright-dark information by drive electronics and the sum of the bright or dark light points serving as information on the magnitude of the roll gap and for controlling the roll gap setting.

Abstract: A spectral analysis device for determining the additions to the steel and an apparatus for generating laser beams are connected via adjustable and switchable couplable optical waveguides to the agitating gas nozzles disposed in the bottom of a converter, the radiation passing through the agitating gas nozzles being converted via metallized agitating gas nozzles and photoamplifiers to measurable intensities.

Abstract: The invention relates to a vertical electroplating cell for processing metal strips in which the strip to be processed running from an upper conductor roll is led to a lower deflecting immersion roll and from there to a further upper conductor roll, the respective descending and ascending strip portion to be processed being subjected in a canal between vertically disposed anodes to the electrolyte flow conducted in circulation at high speed against strip running direction. In such a electroplating cell the circulation of large electrolyte amounts using the minimum possible pump energy is achieved in that the electrolyte flow directed in each case in the canals (6, 7) between the anode rows (5, 7) against the strip running direction are generated via liquid jet pumps disposed on outer canals between rear sides of anode rows and housing walls.

Abstract: To determine the thickness profile of rolled metal sheets by measuring the absorption of X-rays a slit diaphragm is used which is rotatable about the imaginary center axis of the X-ray tube, the rotation consisting of a reciprocating movement lying in a range of less than 36.degree.. Between the reversal points of the rotation the rotational movement takes place in steps with rest intervals lying therebetween.

Abstract: A method and apparatus for a very exact correction of the thickness profile of strip rolled in a multi-stand hot strip mill. A measuring device determines the distribution of tensions in the cross-section of the strip (19). The measuring values are processed in a computer (32) to manipulated variables for a swinging or tilting device and a roll bending device (42). The roll bending device (42) is installed at the end of a hot strip mill train, and one or several roll swinging or tilting devices with measuring devices are provided, as seen in rolling direction, before the roll bending device (42).
