Abstract: In order to analyse the sample of a solution according to the analysis method using fluorescent X-rays, a certain amount of the sample of the solution which is to be analysed is impregnated in a thin porous sheet, for example by the dripping method, and the sheet is dried so that the solvent evaporates. Placed on a suitable support, for example, the sheet is placed in a vacuum atmosphere or in a helium-gas atmosphere so that the primary X-rays are irradiated and it is possible to detect the wavelength or the intensity of the fluorescent X-rays generated from the solute which remains in the sheet. The concentration of the solution may be changed by a concentration or dilution so that it is possible to generate a suitable intensity of fluorescent X-rays. The sampler is made of porous laminar material which is impregnated with the sample of the solution it is desired to analyse and it is dried so that only the solute of the solution remains in the sheet. The circular edge of a support is joined to the circumferential edge of the sheet so that the central part of the porous sheet is sufficiently separated from the circumferentially formed support.

Title: Method and apparatus for vulcanizing tyres.
IPC: B29D30/06
Filed: 1985-11-18
Abstract: A method and apparatus for vulcanizing pneumatic vehicle tires where the tire beads, in the mounted state, are disposed on the radially inner periphery of a rim next to the essentially radially inwardly extending rim flanges. In order to obtain tires having a long service life and tire beads with a good sealing quality, it is proposed that the tire be vulcanized in essentially the proper contour for operation. Two, respectively radially segmented, bead-forming rings that have a variable diameter and can be displaced axially are provided. For the purpose of vulcanizing the sealing surfaces disposed in the interior of the tire so that these surfaces will rest on the rim in an airtight manner, the bead-forming rings are introduced, in a radially retracted state, into the interior of the tire blank, whereby at least one of the tire beads is ovally deformed. The segments of the molding rings are subsequenty extended to an annular radial diameter whereby the molding surface portions of the molding rings can be moved axially outwardly over the tire beads without deforming the latter. The molding rings are then moved axially outwardly over the tire beads and then retracted to their smallest diameter, and are locked into position, whereupon the tire blank is vulcanized in a mold.

Abstract: Bei der Magnetisierung von vielen, gleich stark oder teilweise verschieden stark magnetisierten Teilchen können sich durch Anlagerung der Teilchen aneinander Ketten bilden, die im wesentlichen in Richtung der vom Magnetscheider erzeugten magnetischen Induktion ausgerichtet sind. Aufgabe der Erfindung ist es, einen Magnetscheider zu schaffen, der diese Nachteile vermeidet. Erfindungsgemäß wird dies dadurch erreicht, daß im Scheidevolumen die magnetische Induktion annähernd senkrecht auf den Gradienten des Magnetfeldes steht. Die Erregerspulen (3 und 5), die oberhalb der Symmetrieebene (2) angeordnet sind, sind z.B. im positiven Sinn stromdurchflossen, die Erregerspulen (4 und 6), die unterhalb der Symmetrieebene (2) angeordnet sind, sind dementsprechend ebenfalls im positiven Sinn stromdurchflossen. Durch die gleichsinnige Stromdurchfluß-Anordnung baucht der magnetische Fluß zwischen den Spulenpaaren (3, 5) einerseits und (4, 6) anderseits aus, so daß ein Gradient des Magnetfelds entsteht, der annähernd senkrecht auf die durch die Spulen erzeugte magnetische Induktion steht, und im ringkanalförmigen Scheidevolumen (7) eine annähernd konstante Scheidekraftdichte erzeugt wird.
