Abstract: Systems and methods for providing access rights may include a first computing system that receives a request to link an enterprise account of the first computing system to a second computing system. The first computing system may authenticate a user, receive a selection of one or more access rights, and one or more accounts of the enterprise account, via an application interface of the second computing system, and generate an access token for transmission to a computing device of the user, where the access token identifies the one or more access rights and the one or more accounts. The first computing system may transmit the access token to the computing device, to provide the computing device access to the one or more accounts according to the one or more access rights, of the first computing system, via the second computing system.

Abstract: Drawing, especially cold-drawing, or hot-drawing, or other heat-treatments, of spin-oriented crystalline polyester filaments, and particularly polyester feed yarns, that have been prepared by spinning at speeds of, e.g., 4 km/min, and have low shrinkage and no natural draw ratio in the conventional sense, provides useful technique for obtaining uniform filaments of desired denier and thereby provides improved flexibility to obtain filaments and yarns mixed with nylon filaments.

The resulting uniform filaments have useful properties that are improved in certain respects.

Abstract: Air-jet texturing with drawing, especially cold-drawing, or hot-drawing or other heat-treatments of spin-oriented crystalline polyester filaments, and particularly polyester feed yarns, that have been prepared by spinning at speeds of, e.g., 4 km/min, and have low shrinkage and no natural draw ratio in the conventional sense, provides useful technique for obtaining uniform drawn filaments of desired denier and thereby provides improved flexibility to obtain air-jet textured filaments and yarns of various denier. The resulting yarns have useful properties that are improved in certain respects.

Abstract: A method of sealing the surfaces of porous carbon and graphite articles by impregnation at ambient pressure using a treating solution comprising a high temperature polymerizable liquid resin. The liquid treating solution, when upon the surface of the article, is of sufficiently low viscosity to allow infiltration of the treating solution into the pores of the surface of the article. The treated article then undergoes a controlled heating cycle, which cures the infiltrated resin in situ. Subsequent treatments and surface conditioning techniques are utilized to produce a thin, level, liquid and gas impervious coating on the surfaces of the article.
