    摘要： A process and apparatus for the continuous conversion of isotropic carbonaceous materials into anisotropic mesophase pitch is disclosed. The invention disclosed herein addresses the need for lower production costs compared with traditional batch mesophase conversion of isotropic pitch. A unique thermal processing and in-process separation of reacted mesophase from the continuous matrix of fresh or partially reacted isotropic pitch is provided. Potential uses are for further continuous processing into carbon fibers or carbon form densification.

    摘要： A railroad rail includes a body defining a first section and a tapered second section with the body defining a head section, a web section depending from the head section, and a base section depending from the web section. The head section, the web section, and the base section define an end surface configured to mate with a corresponding end surface of a complementary railroad rail when joined together. The railroad rail is formed from a single bent railroad rail having only a single bend defined by the head section, web section, and base section of the body of the railroad rail.

    摘要： Pitch production systems utilizing coal tar or decant oil for coal. or petroleum based pitch are disclosed. Total pitch production yields are increased by heat treating distillate fractions from the pitch production process. A heat treatment system and process are disclosed in embodiments. The heaviest distillates having the highest molecular weights are subjected to heat treatment, though other embodiments contemplate heat treating a variety of combined distillate fractions. The heat treatment systems require heat soaking the distillate(s) at elevated temperatures of 459-535° C. at a near-constant temperature with near-uniform flow. A fraction of the heat-treated distillate may be reintroduced to the pitch production system as part of a continuous process.

    摘要： A rail joint bar for use in an insulated lap joint assembly includes a longitudinal extending body defining a plurality of holes therein for receiving fasteners. The body has a first end and a second end positioned at opposite ends of the body relative to a longitudinal direction of the body. The body is bent forming a first portion adjacent to the first end, a second portion adjacent to the second end and spaced from the first portion in the longitudinal direction, and an intermediate portion defined therebetween and positioned between the first and second ends. The first portion and the second portion are substantially parallel to each other and, and the intermediate portion of the body is configured to accommodate an increase in thickness of a web section at a point where two railroad rails are joined.

    摘要： A rail joint arrangement comprises two rails. The rails have adjacent rail ends separated and thereby forming a gap. The rails have a top end containing a rail head and a bottom end. The gap is defined between the top end and the bottom end of the rails, and the width of the gap is non-uniform throughout its entire length. In addition, the rail joint arrangement comprises at least one electric insulator positioned within the gap. The rail joint arrangement is fastened together by a rail joint bar attaching the two rails together.
