The shrinkage yarn C has at least one effect component A that irreversibly elongates itself upon heat treatment, and at least one shrinkage component B that shortens itself upon heat treatment. The components A and B are bound together by nodes, wherein the number (y) of nodes per meter in the yarn C is predetermined as a function of the yarn count (x) of the transverse thread system so that the number (y) of nodes exceeds a minimum value and increases proportionally above the minimum value as a function of the yarn count (x).

Abstract: The invention relates to a woven fabric, in which at least one of the intersecting yarn systems contains a differential shrinking yarn (C), which consists of at least one decorative component (A) that elongates irreversibly during thermal treatment and at least one shrinking component (B), which contracts during thermal treatment. The components (A) and (B) are interconnected by means of entangled knots. The number of entangled knots per metre of yarn (C) in the finished woven fabric corresponds to the number of yarns in the intersecting yarn system.

After the entanglement process, the unsized yarns are interwoven as a warp with a weft in such a way that the number of weft yarns in the finished woven fabric is (X). The woven fabric obtained in this manner is subsequently thermally treated.

Abstract: A refractory pipeline having ceramic pipe sections with joints therebetween located at areas where in which there are the greatest temperature differences in the pipeline. Adjacent pipe sections are connected together by shoulders at the ends of each such section, the shoulder of one pipe section being radially outside the shoulder of an adjacent section. A further pipe section is pushed over the joint so as to form a gastight seal by defining a space in communication with a borehole through the one shoulder and a peripheral groove in the other shoulder. A pressure cushion is provided in the space by applying a barrier medium under pressure to the space and thereby through the borehole to the peripheral groove.

Abstract: A method for the production of ceramic-metal composite materials, in which ceramic materials are infiltrated with molten metal, includes building up a porous ceramic material of several layers by spraying on a base body, the thickness of the layers being between 10 and 150 microns with an average pore radius of between 100 and 1,000 nm, an open porosity of 5-14% and an overall porosity of 5-30%; and filling molten metal into the pore volume up to a residual pore volume of 0.1 to 10%, based on the initial porosity. In an alternate embodiment, a gradient structure of the ceramic is created by increasing or decreasing the particle size of the ceramic material while spraying layers. In the gradient structure, infiltration of molten metal is greatest in the layers sprayed with particles having the largest diameter.

Abstract: Process and apparatus for manufacturing heat exchangers from ceramic sheets, wherein different flow channels are stamped from or pressed into the sheets, and the formed sheets are joined together with a laminating agent. The stacking of the individual sheets is effected using apparatus in which the sheets are transported to the forming means, applicator means and laminating means by horizontally and vertically displaceable, rotatable and pivotable suction plates. The organic component of the ceramic sheets is expelled from the heat exchanger block obtained in two heating steps with an intermediate forming operation to bring the heat exchanger block to its final dimensions, and the block then fired between 1,200.degree. to 1,700.degree. C. The actual sintering temperature depends on the particular ceramic used, which may comprise Si.sub.3 N.sub.4, SiC, cordierite and/or semiconductive barium titanate compounds.

Abstract: By use of new ion conducting but non-electron conducting mixed crystal compounds of the type sodium zirconium phosphatosilicate as the ceramic board material for electronic circuitry it is possible to provide full integration of electronic, electro-chemical and optical components, because the boards simultaneously constitute the solid electrolyte for the miniaturized batteries serving as energy source, and for an electrochromic display system. An illustrative practical embodiment involves housing within a ceramic multi-layer structure a battery with positive electrode and negative electrode for a quartz driving circuit and an electrochromic (ECD) display controlled by an microprocessor. For the flow of current through the ECD there is used a secondary element formed of a WO.sub.3 electrode and a Na-tungstenate electrode as the counter electrode, the WO.sub.3 segments assuming a blue color due to diffusion of Na.sup.+ ions.
