Patent DE-88374-T1 (DE)
IPC: C03B37/025
Filed: 1983-03-03
Abstract: The diameter of the supporting-tube of the preform (TQ) can be kept constant by this method, notwithstanding the tube tendency to collapse owing to the high-temperature necessary to reactant synthesis reaction and raw-material deposition. 
<??>The diameter is controlled by generating between the internal and the external tube surface a pressure difference variable in a way inversely proportional to the diameter of the tube itself and to the total gas flow at the input. 
<??>The device (GP) allows the generation of the required pressure loss at the output and the separation of raw-material solid particles from residual gases.
Patent DE-161995-T1 (DE)
IPC: B07B9/02
Filed: 1985-03-19
Abstract: The subject matter of the invention mainly relates to the technical areas of foundry, manufacture of parts by casting metal in moulds. The process consists in that after moulding the parts and stripping them from the moulds which were broken, during a first cycle the mixture resulting from the knock-out is recovered. This mixture being stored. This mixture is directed from the storage place to an intermediate container; then the mixture from the intermediate container is fed up to a sieve grading separator unit allowing to separate the grains or particles in several different grading batches; each one of these batches is directed to a separating table designed for separating chromite from silica; the chromite on the one hand and the silica on the other hand are recovered in containers. This invention mainly applies to the recovery of components of different densities, especially chromite and silica.
Patent DE-310298-T1 (DE)
IPC: G01F23/26
Filed: 1988-09-22
Abstract: An apparatus and method for determining tank contents employs processing means for comparing sensing outputs (e.g. derived from a liquid level sensor (4)) with metering outputs (e.g. derived from a volumetric totaliser connected to a dispenser (2)) in order to determine errors in the sensing outputs and thereby to provide a corrected calibration characteristic. In the preferred embodiment (which applies to a storage tank (1) containing petroleum), the calibration characteristic is refined, in stages, by applying incremental changes to a conversion factor used in determining data values related to the sensing output and by computing correlations to determine an optimum calibration characteristic. A corrected calibration characteristic (stored in a PROM) may be subsequently employed in equipment for displaying tank contents.

Title: Expansion anchor
Inventor: LINKA MARTIN
IPC: F16B13/06
Filed: 2005-09-29
Abstract: The invention relates to an expansion anchor (1) comprising an expansion sleeve (5) that can be expanded by the insertion of an expansion cone (2). The aim of the invention is to reduce the wall thickness of the expansion sleeve (5) with an annular step (9) on a front edge (7) facing the expansion cone (2). To this end, the expansion sleeve (5) comprises an edge (10) extending in the peripheral direction on the front edge (7), and an edge (11) extending in the peripheral direction on the annular step (9), said edges being pressed into a borehole wall when the expansion sleeve (5) is expanded by the cone (2). This improves the anchoring of the expansion anchor (1) in a borehole. The invention is also advantageous in that the axial fixing of the expansion sleeve (5) in the borehole is improved, thus then improving a post-expansion behaviour during the enlargement of the borehole as a result of crack formation.

Abstract: 2,6-Diacetoxynaphthalene (DAN) is produced by subjecting 6-acetoxy-2-acetonaphthone (AAN) to a Baeyer-Villiger oxidation using a peroxy compound, e.g., peracetic acid, as oxidant under conditions such that the reaction mass contains no more than about 0.1 wt.% of a mineral acid based on the weight of the initially added pure peroxy compound. The AAN is preferably produced by subjecting 2-naphthyl acetate to a Fries rearrangement or 2-naphthol to a Friedel-Crafts acetylation, to produce 6-hydroxy-2-acetonaphthone (HAN), e.g., using hydrogen fluoride as catalyst, and acetylating the HAN, e.g., with acetic anhydride.
