Abstract: Processes for the treatment of asphalt pavements such as asphalt roads and sidewalks to make them more resistant to corrosion, that is, resistant to deterioration and disintegration, which comprises applying to the asphalt pavement a liquid composition consisting essentially of finely divided particles of a solid substance having a hardness between 8.5 and 9.5 on the Moh scale, such as a mixture of particles of silicon carbide and electrofused alumina, dispersed in a vehicle consisting of one or more organic synthetic resins and one or more solvents for the resin.

Abstract: For manufacturing molded and impregnated parts from epoxy resin compositions, a reactive epoxy resin is employed which hardens more slowly at higher temperatures (120.degree. to 180.degree. C.) than at lower temperatures (80.degree. to 110.degree. C.). The reactive epoxy resin composition is applied at the higher temperature and subsequently hardened at the lower temperature.According to the method of the invention, molded parts (e.g., solution pump heads), cast-in electrical components (e.g., four-ring stray field electrodes) and impregnated parts are manufactured.

Abstract: Materials and methods are shown for increasing the antioxidant protection of polyolefin insulation, such as low density polyethylene insulation on electrical conductors. The materials may be applied in the field to increase the service life of in-place cable. The material is typically applied by brushing or spraying a lacquer-based carrier containing the inventive stabilizer onto the insulation to be protected. The stabilizer migrates into the polyolefin insulation, typically increasing the service life of antioxidant depleted cable by several years.

Such urethane polyethers are advantageously prepared by reacting a polyether polyol such as a hydroxy terminated polypropylene glycol with an isocyanatoalkyl ester of an ethylenically unsaturated acid such as 2-isocyanatoethyl methacrylate.

Abstract: Phyllosilicate minerals which exhibit in their structure, sequentially, octahedral layers containing magnesium, aluminum and/or iron oxides and tetrahedral layers of silica, are superficially etched with dilute acid to remove the outer octahedral layer under controlled conditions which preserve the basic structural integrity of the mineral substrate. The acid etch exposes silanol groups on the outer silicate layer of the mineral so that they become available to form silicon-to-oxygen-to-silicon-to-carbon bonds through condensation with organo-silanes. The condensation of the organo-silane with the conditioned mineral surface is accomplished by mixing the acid etched silicate mineral with the organo-silane in a suitable solvent system under mild conditions.The organo-silane may be chosen from either of two classes: those which impart an oleophilic surface to the mineral; or those which enable the mineral surface to form additional chemical bonds with reactive sites within certain polymers and prepolymers.

Abstract: Method for vacuum depositing corrosion and oxidation resistant alloy coatings on turbine buckets having leading edges and trailing edges, with simultaneous rotation of the turbine buckets about their longitudinal axis in a vapor stream above a vapor source. The time of stay of each element of the surface above the vapor source is varied during a 360.degree. rotation such that it is shortest when the leading edges and the trailing edges are pointed towards the vapor source and longest when the concave and convex flanks are presented to it.

Abstract: The disclosure is of a method for improving the acid resistance, hydrophobicity, oleophobicity and dust or dirt release properties of synthetic organic fibers. The method comprises coating the fibers with an aqueous dispersion of polytetrafluoroethylene particles in the presence of a water soluble, chromium complex of a long chain fluorochemical. The method is particularly advantageous for improving polyaramid fibers such as Nomex fibers in fabrics to be used as a filter means.
