Abstract: A bearing assembly of a power generation structure including, a rail; and a housing adapted to support the rail; where the housing includes a fixed housing portion attached to a support beam, and an adjustable housing portion attached to rail, where a low friction material is present at an interface between an exterior surface of rail and an interior surface of the adjustable housing portion, where the adjustable housing portion is capable of self-aligning adjustment of at least a portion of the rail out of alignment with a central axis of the support beam.
Abstract: Provided herein are processes for the separation of acetonitrile from low-purity feedstock streams. The provided processes are particularly useful for isolating acetonitrile at high purity from chemical manufacturing waste streams that include methanol, water, and allyl alcohol.
Abstract: An adhesive layer can include a polymer blend of a first polymer and a second polymer. In an embodiment, the first polymer can be a modified fluoropolymer. In another embodiment, the second can be a non-fluorinated polymer. In a particular embodiment, the adhesive layer can include greater than 60 wt. % of the first polymer for the total weight of the polymer blend. A bearing can include the adhesive layer disposed over a substrate.
Abstract: This disclosure relates to polysiloxanes and polysiloxane compositions having dual-curable properties, to methods for forming articles from such compositions, and to articles formed thereby. In one embodiment, the polysiloxane comprises at least about two alkenyl groups and at least about two (meth)acryloyl groups.
Abstract: Some fishing boats include a livewell system. This document describes livewell systems that have multiple modes of operation. The modes of operation include, at least, a first mode with a lower water level and a second mode with a higher water level. While the livewell is operating in the second mode, the tank is nearly full of water. Accordingly, with a nearly full tank, the water in the livewell will resist sloshing around while the boat is navigating rough seas or travelling at high speeds or for long distances. Moreover, the health of the fish in the livewell will be protected because of the water's lessened tendency to slosh around in the livewell.
Abstract: A valve including a valve body including an inlet opening and a plurality of outlet openings; and an actuating gate adapted to seal at least one of the plurality of outlet openings, where the actuating gate is adapted to rotate eccentrically about a central axis while also translating in a direction perpendicular to the central axis upon actuation.
Abstract: A liquefier tube for an additive manufacturing system, including a body provided with a feed channel including a feeding portion having a first diameter, an outlet portion having a second diameter, the first diameter being larger than the second diameter, and a transitional portion interconnecting the feeding portion and the outlet portion. The transitional portion has a decreasing third diameter from the first diameter to the second diameter, and an inner surface of the transitional portion is provided with a plurality of ribs. Methods of manufacturing the liquefier tube.

Abstract: A method for tuning characteristics of a polyamide nanofiber nonwoven comprising the step of targeting a specific average nanofiber diameter and/or a specific relative viscosity for the polyamide nanofiber nonwoven. The specific average nanofiber diameter is within a range from 100 nm to 1000 nm and/or the specific relative viscosity is within a range from 5 to 75, e.g., from 15 to 50. The process further comprises the steps of extruding a polyamide composition having a moisture content with a pressurized gas through a fiber forming channel having a channel temperature to form the polyamide nanofiber nonwoven having the target average nanofiber diameter and/or relative viscosity and controlling the moisture content, the pressure of pressurized gas, and/or the channel temperature based on the specific average nanofiber diameter and/or the specific relative viscosity.
Abstract: An inner drum that includes a coupling part having an external surface and an internal surface, wherein the internal surface contains splines. An annular trough is engaged to the exterior surface of the coupling part. A circular wall contains a plurality of appendages extending upward from the circular wall. At least one slot is disposed within the appendages for receiving a snap ring.
Abstract: A process for converting caprolactam to aminocapronitrile, the process comprising contacting a caprolactam feed with ammonia and an aluminosilicate zeolite catalyst to produce an aminocapronitrile product, wherein the catalyst comprises less than 5 wt. % of an active metal, and wherein conversion is greater than 50% and selectivity for aminocapronitrile is greater than 91%.
Abstract: A fiber is made with a polybenzimidazole (PBI) polymer with a phosphoric acid pick-up (APU) in the range of 1-25% (PBI-p fiber). The PBI-p fiber may have a LOI ?50% and/or an initial thermal decomposition temperature in air of ?555° C. A method of making a phosphonated polybenzimidazole fiber comprises the steps of: spinning an untreated PBI resin into a PBI fiber; treating the PBI fiber with phosphoric acid, and thereby obtaining a PBI fiber with 1-25 wt. % phosphoric acid APU.
