Abstract: A process for the substantially complete regeneration into sulphuric acid and metal oxides of a raw material comprising a concentrated solution or slurry of metal sulphates containing sulphuric acid and/or of a filter cake of metal sulphates containing sulphuric acid, in which process the metal sulphates are decomposed at 700-1200°C to form metal oxides and a SO.-containing gas which is subsequently converted into sulphuric acid, characterized by the steps of
     (a) adjusting the raw material to a content of at least 60% by weight of H 2 SO 4  in the liquid phase, calculated on the assumption that the metal sulphates contain 1 molecule of water of crystallization per metal atom, and at the same time ensuring thatthetotal amount of water, calculated as the sum of water present in the components of the material obtained by a subsequent neutralization step and the water formed by the complete neutralization of the sulphuric acid, does not exceed 5 molecules of water per metal atom,   (b) neutralizing the material obtained in step (a) approximately completely by the addition of metal oxides recycled from step (f) below, the amount added being approximately   equivalent to the amount of acid in the material, (c) granulating and drying the product of step (b),   (d) heat-decomposing the granulated product optionally in the presence of a reduction agent to form metal oxides and SO 2 ,   (e) conducting the SOrcontaining gas from the decomposing step (d) to a sulphuric acid plant for conversion into sulphuric acid.   (f) recycling part of the oxides formed in step (d) to neutralizing step (b), and   (g) recovering the remainder of the oxides formed in step (d).

Title: Method for producing plastic three-dimensional transparent honeycomb structures
Inventor: MIELKE MANFRED
IPC: F24J2/50
Filed: 1985-02-15
Abstract: These structures can be produced by thermoforming (heat-forming or deep-drawing) of plastic films or boards to form rib-shaped structures of 3 to 15 mm in depth and 3 to 100 mm in width, at a spacing of the respectively selected width and based on the length, which is 3 to 30 times the depth, and stacking these formed articles on top of one another in outer frames, rolling them up or laying them down as an endless strip. By adhesively bonding, welding or heat sealing the rib-shaped depressions by means of a film or with one another, the formed articles produced by thermoforming are given additional mechanical strength due to the air or gas cushions produced. For protection against external influences, the transparent honeycomb structures produced in this manner are covered on one or both outer surfaces with a transparent board or film, adhesively bonded or sealed. The heat-insulating property of the three-dimensional translucent honeycomb structure is increased by filling only the rib-shaped depressions or the entire translucent honeycomb structure with a gas having a high molecular weight.

Abstract: The method of planarizing polysilicon-filled trenches involves first filling the trenches (12) with an undoped polysilicon (14) until the upper surface (18) is substantially planar. The polycrystalline silicon (14) is then heavily doped by means of diffusion of a dopant from the upper surface. The time and temperature of the diffusion are carefully controlled providing for the dopant to penetrate the polysilicon to a depth (16), level with the tops of the trenches. A selective etchant is then utilized which removes the heavily doped polysilicon (16) and leaves the undoped polysilicon (17) untouched in the trenches (12).

Abstract: A hydraulic piston-valve-type control valve that includes a housing in which a control piston is longitudinally displaceably disposed. By means of annular recesses, and hence control surfaces formed on piston collars about a piston core, the control piston regulates at least one fluid stream that flows through the housing. This regulation is effected by coupling the recesses between the piston collars, while appropriately longitudinally shifting the control piston, with annular control chambers on the housing side. The collars of the control piston are provided with control edges that progressively release the control chambers. The problem with heretofore known valves was that an undesired sudden increase in the flow forces could not be avoided. In addition, the manufacture of the corresponding configurations of the control edges was complicated and expensive. To remedy this problem, the course of the control edges that release or close the control chambers on the housing side, when viewed in the circumferential direction of the control piston, has no segment that extends linearly and at right angles to the center line of the piston. Each control edge follows a symmetrical course relative to a central cross section taken through its circumferential development, and each control edge also at least twice provides for the full cross-sectional opening area of the control piston.

Abstract: A high contrast developing process is described for use after pre-exposure to UV-visible radiation to produce increased sensitivity during lithographic processing of positive resists layers. Compared to samples which have not been subjected to the methods of this invention, sensitivity increases of a factor of 2-4 are to be expected. An additional benefit of low film loss from unexposed resist is obtained. The system disclosed is applicable to lithographic exposures utilizing electrons, photons (eg. UV-visible, x-rays, etc.) and atomic or molecular charged particles. Specifically, as a result of the increased sensitivity, higher throughput during lithographic processing for the fabrication of photomasks and semiconductor devices is realized.
