Abstract: A rail fastener sealing system comprises a dowel having a substantially cylindrical elongated body and a dowel passage configured to receive a fastener that secures a rail to a rail tie. The sealing system further includes a seal positioned on an end of the dowel. The seal includes a flexible body having a central passage extending through the flexible body and a lip extending circumferentially around an opening of the central passage. The lip of the seal is disposed adjacent the end of the dowel and at least a portion of the flexible body of the seal is positioned within the dowel passage.

Abstract: A semi-autonomous spray applicator system for a plurality of elongated members. The semi-autonomous spray applicator system provides a plurality of spaced apart pockets, wherein each pocket establishes a centerline and proximal endpoint for the pocketed elongated member. A rail detection system of the semi-autonomous spray applicator system is configured to sense the opposing distal endpoint of each elongated member as the longitudinal length of each member may vary pocket to pocket. A traversing applicator head operatively associated with the system applies adhesive spray to a longitudinal edge and a distal end of sensed, pocketed elongated members, wherein the application of spray is selectively controlled by way of a user interface.

Abstract: A method of generating hydrogen from an offgas includes obtaining the offgas from a renewable diesel unit (RDU). The method further includes inputting the offgas to a steam methane reformer (SMR).

Abstract: In some embodiments, a shelving system configured to be coupled to a wall and supported on a support surface is provided. The shelving system can include a fixed shelving unit extending laterally from the wall, and a movable shelving unit. The fixed shelving unit can include a vertical support coupled to a base. The movable shelving unit can also extend laterally from the wall, and can be movable through a shelving path. In some embodiments, the shelving system can be provided with a floor leveling system enabling a user to easily and quickly level the shelving system. Also, in some embodiments, the movable shelving unit includes a damper that slows the movable shelving unit prior to being stopped.

Abstract: An electrode for use in miniaturized sensor applications includes an electrically conductive element, a first layer of a salt on the surface of the conductive element having a common cation with the conductive element, a second layer of a second salt coating the first layer, the second layer having a common anion with the first layer, and a membrane covering the second layer, wherein the electrode is completely anhydrous when formed. The membrane may be selected to form either an ion selective electrode or a reference electrode.
