Patent DE-10314926-A1 (DE)
IPC: E01B1/00
Filed: 2003-04-01
Abstract: The invention relates to a method for adjusting the position of a precast concrete slab (1), in particular to the support pillar for a carriage way for high-speed transport means. The inventive slab (1) is supported by a foundation consisting of a sub-layer made of a hardenable material and a base bearing layer (5) of the foundation and is brought into a predetermined position prior to the sub-layer arrangement with the aid of several vertical bars (11) which are used as auxiliary adjusting elements (4, 4'). The inventive method is characterised in that at least two vertical bars (11) rest against a bearing block (13) which is disposed on the bearing layer (5) and displaceable in a longitudinal and/or transversal direction of the slab (1). Said invention makes it possible to arrange the appropriate auxiliary adjusting means and a corresponding precast slab.

Title: Verfahren zur Ausbildung eines Zinküberzugs
Inventor: IWADE TANKANOBU
IPC: C23C22/73
Filed: 2003-06-11
Abstract: Die vorliegende Erfindung liefert ein Verfahren zur Ausbildung eines Zinküberzugs, wodurch ein Chromatfilm ausgebildet werden kann, der einer Wasserstoffversprödungs-Schutzbehandlung standhalten kann, und zwar durch Optimierung der Bedingungen, unter denen das Chromatieren durchgeführt wird. DOLLAR A Das Verfahren zur Ausbildung eines Zinküberzugs umfaßt das Verzinken der Oberfläche eines Werkstücks auf Eisenbasis, das Behandeln der Oberfläche der Verzinkungsschicht mit dreiwertigem Chrom und das Behandeln des Werkstücks, um es vor einer Wasserstoffversprödung zu schützen. Wenn das mit dreiwertigem Chrom behandelte Werkstück aus dem Bad von dreiwertigem Chrom genommen wird und getrocknet werden soll, wird das Werkstück nicht bei hohen Temperaturen getrocknet, sondern bei einer Temperatur von bis zu 40 DEG C. Auf diese Weise kann durch die Behandlung mit dreiwertigem Chrom ein Chromatfilm ausgebildet werden, welcher der Wasserstoffversprödungs-Schutzbehandlung standhalten kann. Infolgedessen können die Galvanisierungs- und Chromatisierungs-Schritte in einer Galvanisiervorrichtung nacheinander durchgeführt werden, und die Herstellungskosten können durch Verringern der Zahl der Bearbeitungsschritte gesenkt werden.
