Abstract:
The invention relates to a strip of steel having a variable thickness in its length direction with at least thicker sections and thinner sections, the strip having been cold rolled to form the thicker and thinner sections, one thicker and one thinner section having a length of at most a few meter, which strip has been annealed. According to the invention, the annealing has been performed by continuous annealing.

Abstract:
A bar made of noble metal or of an alloy having a noble metal with a mass mB is divided into n x m small bars 2,3, each of which has a specified mass mk, wherein both n and m are a natural number = 2, and a material connection (8) is present between the directly adjacent small bars (2,3). A further bar is connected to a backing (13) on which the small bars are removably attached. A method for producing the bar consists in dividing same while retaining a material connection or arranging on a backing.
Abstract:
The present invention concerns a metal membrane for a low-temperature-fluid storage tank wherein horizontal and vertical creases are formed and both creases intersect each other. In the intersection of the creases, a bidirectional elastic member connected to each crease is formed so that the creases can be horizontally and vertically elastic. The bidirectional elastic member protrudes and is shaped like either a pyramid, a dome or a cross. Each metal membrane is welded into a unit panel and the edge of each metal membrane is welded with the common edge of another adjacent metal membrane to keep a cargo warehouse air-tight, and ultra-low-temperature LNG is stored inside the cargo warehouse, so when the metal membrane contracts due to thermal deviation, the present invention reduces plane rigidity and, at the same time, equalizes plane rigidity of two intersecting directions. Accordingly, durability is increased, air-tightness is maintained and storage of low-temperature liquid is stabilized, regardless of extreme thermal deviation. Furthermore, fabrication of the storage tank is improved because the present metal membrane is easily clamped by a clamping unit of a welding robot or a transfer device.
Abstract:
The invention relates to the production of segmented nanowires and components having said segmented nanowires. A template-based method is preferably used for producing the nanowire structural element, wherein electrochemical deposition of the nanowires takes place in nanopores. A plurality of nanowires thus is generated in the template foil. For the electrochemical deposition of the nanowires, an alternating sequence of cathodic deposition pulses and anodic counterpulses is performed. Segmented nanowires can be produced thereby.
Abstract:
Mit der Erfindung lässt sich planmäßig ein Metallflachprodukt mit einer so feingliedrigen, stochastischen bzw. quasi-stochastischen Oberflächenstruktur zur Verfügung stellen, dass sie nach einer automobil-typischen Lackapplikation wenn überhaupt, dann nur schwach visuell wahrnehmbar sind. Gleichzeitig erfolgt bei einer erfindungsgemäß beschaffenen Oberflächentopographie der Wechsel zwischen den Bergplateaus und den Tälern über steile Flanken. Auf diese Weise ist erreicht, dass die Morphologie der Feinblechoberfläche praktisch unabhängig von der eigentlichen Tiefe der Täler ist. Im Ergebnis ist daher die Morphologie der Feinblechoberfläche eines erfindungsgemäßen Metallflachprodukts auch unabhängig vom Dressiergrad, der beim Erzeugen der Feinblechtextur durch ein Dressierwalzen angewendet wird.
