Abstract: A process for producing a laminated panel core made of stainless steel includes the step of preparing a core of the laminated panel by subjecting stainless steel foils to repeated outward and inward foldings in a constant mode in one direction to make a plurality of multi-layered folded sheets of stainless steel. An adhesive is applied to a portion of the surfaces of the folded sheets and a desired number of the multi-layered sheets are laminated. The adhesive causes the sheets to adhere to one another in the areas of application of the adhesive. The laminate is sliced in a plane perpendicular to the plane generally defined by each of the multi-layered sheets into an appropriate small thickness and is extended and deformed in a plane parallel to the plane in which the laminate is sliced and in the direction of lamination of the sheets. A multi-layered sheet for use in a process for forming laminated panels and a stainless steel foil core for use in a laminated panel are also disclosed.

Abstract: A process cell (1) for the analysis of liquids, particularly cloudy ones with high light absorption, has a measuring chamber (2) through which flows said liquid, which has two windows (3) lying at a short distance opposite each other for the passage of the measuring light. The latter are held in holding devices (4) which are supported by a common frame (5), which is sufficiently movable relative to the cell housing (6) to be able to perform heat movements. The frame (5) and the holding devices (4) consist of a material with essentially the same coefficient of thermal expansion, so that changes in length of the holding devices (4) occurring upon temperature changes can each time be compensated so that the distance between the two windows (3) practically does not change and thus no changes in the measuring results determined by temperature fluctuations occur.
