摘要： Acidification of impure alkali or ammonium tungstate or molybdate solutions prior to electrodialysis to produce tungstic acid or molybdic acid is carried out by the addition of pure tungstic acid or molybdic acid as the salts of tungsten isopolyacids or molybdenum isopolyacids, respectively. This is less expensive than using pure HCl or H.sub.2 SO.sub.4 and prevents contamination with chloride or sulfate ions. The pure tungstic acid or molybdic acid is isolated from the product.

摘要： The invention relates to the low molecular weight compatibilizing additive package having many advantageous effects, which improves the compatibility of different thermoplastic and/or thermosetting polymers and/or fillings, functional additives just as composites containing natural and/or artificial strengthening fibres, and relates to its preparation and application processes. It has been found, that selective grafting of highly reactive α-olefins having C20-C40 average carbon number or hydrocarbon polymers containing more than 80% α-olefins and having an average molecular weight significantly lower than usual ( Mn≦3000), with highly reactive monomers or their mixtures, then further chemical modification of the functional groups of the prepared intermediates, just as its simultaneous application with unsaturated fatty acid ester—dicarboxylic acid adduct of high acid number, or its ester-, ester amide-, amide-, or imide derivatives result in products being different in structure from the known compatibilizing additives.

摘要： The present invention provides an apparatus that fastens elements of a frame assembly. The frame assembly implements fasteners as independent elements from both a housing and a corresponding housing cover. Exemplary embodiments of such fasteners may include the hook nut fasteners disclosed herein. Generally, such fasteners include a central portion providing a contact area disposed in the plane of a housing fastening aperture, an extension tab providing a contact area on a housing interior wall, and an extension block providing a contact area on a housing exterior wall. The extension block may include a hollow portion configured to receive a securing bolt. One advantageous application of the invention relates to automobile motor assembly housings. Specifically, in that embodiment the hook nut fastening assembly reinforces the motor housing and provides additional support to the assembly by reinforcing the joints between an end-cover and a motor assembly main body.
