  • Publication number: 20220097259
    Abstract: A multi-port single screw extruder combining a heated plastication barrel having a first entrance port and an exit port on opposing ends of the barrel and a second entrance port intermediately positioned therebetween; a first hopper positioned to deliver ingredients to the first entrance port of said barrel; a second hopper positioned to deliver ingredients to the second entrance port and a helical plastication screw rotatably carried within the barrel and running the length thereof between the first entrance port and exit port that is operable to rotate and transmit the ingredients along the length of the barrel; wherein the plastication screw includes a distributive mixing element located between at least one additional entrance port and the exit port, the minor diameter of the plastication screw is reduced in advance of each additional entrance port sufficient to reduce the barrel pressure at each entrance port to a level that permits the addition of ingredients to the barrel through the entrance port, and

  • Publication number: 20200283962
    Abstract: A railroad tie formed of a polymeric or polymeric composite material and configured for enhanced mechanical interaction with an underlying ballast. The tie includes at least a top longitudinal surface, a pair of side longitudinal surfaces, a bottom longitudinal surface, and two end faces. At least the bottom longitudinal surface includes a plurality of indentations formed along a length thereof. Additionally, the tie includes at least one serrated edge portion having a plurality of serrations, the at least one serrated edge portion formed along at least part of the longitudinal length of the tie at an edge between at least one of the side longitudinal surfaces and the bottom longitudinal surface to provide for enhanced mechanical interaction with the ballast.
