Abstract: A rotary valve includes a rotor plate, a track plate, and a seal sheet, all housed within a pressure dome. The seal sheet includes little or no polytetrafluoroethylene (PTFE). Is some embodiments, the seal sheet includes about 35-60% bronze. In some embodiments, the rotor plate and/or the track plate include at least one fairing to improve fluid flow performance and reduce likelihood of cavitation.

Abstract: The embodiments presented herein describe a continuous insulation sheathing product to make a building energy efficient and reduce the carbon footprint of the building. The continuous insulation sheathing product also incorporates a specialized fire-retardant chemical in addition to natural fibers. In an embodiment, the continuous insulation sheathing product may be formed via an entanglement and thermal bonding of the natural fibers and a staple fiber. The embodiments presented herein, thus, enable the product to add additional insulation value to roofs and wall assemblies of a building, while providing a continuous layer of performance to mitigate the loss of energy through more conducive members of the roof and wall assembly (e.g., wood or steel framing). Further, the product achieves the above-described advantages using predominantly bio-based materials, thereby, resulting in a lower carbon footprint and providing an environmentally friendly option for consumers.

Abstract: In an embodiment, a surface treatment system to treat a nonwoven material by a chemical emulsion is described. The surface treatment system includes an air compressor to pressurize a tank to deliver the chemical emulsion to one or more spray heads of an emulsion applicator. The surface treatment system further includes the emulsion applicator to treat the nonwoven material by the chemical emulsion. The one or more spray heads are mounted on an adjustable bar of the emulsion applicator, and spray the chemical emulsion on a surface of the nonwoven material. The adjustable bar moves in one or more planes and allows the one or more spray heads to spray the chemical emulsion in a spray pattern of the surface of the nonwoven material.

Abstract: A fairing, in the form of a contoured restriction, submerged on a fluid channel surface of a fluid channel through which liquid flows, re-distributes velocity fields and flow geometries upstream and in some embodiments downstream of a discontinuity, thereby preventing flow separation, reducing cavitation potential and increasing flow capacity. Such discontinuities include, but are not limited to: joints, for example elbow joints, T-joints and Y-joints; valve-trims; entrance regions to centrifugal pumps; and entrance regions to rotary valves, steps, reductions, expansions and ledges. The fairing may be fitted into the channel or integrally fabricated with the channel.

Abstract: Embodiments are related to systems and methods for data processing, and more particularly to systems and methods for clock recovery in a data receiver.

Abstract: 4. A towable sea-going vehicle for carrying communications equipment for in conjunctive cooperation with communications equipment of another vessel comprising:an essentially hollow body having openings in its walls for free flooding and self-bailing of said body;said body having an essentially rounded, gently pointed nose section and a V-bottom portion, said V-bottom portion providing a surface for the planing of said body on the surface of water and providing a face portion for contributing to the hydrodynamic lifting of said body when in an underwater position;buoyancy producing means located in said body to the extent that the weight of said body in air is substantially less than the excess buoyancy of said body when immersed in water;and said body having an upper cambered portion for producing lift when said body is in an underwater position;whereby said communications-carrying vehicle may be towed either submerged or on the water surface at speeds up to and in excess of 35 knots.
