Abstract: Disclosed is a multiple layer substrate that can be used with a top asphalt applicator that eliminates the need for a bottom asphalt applicator and fines applied to the bottom asphalt layer. A low porosity or impermeable bottom layer prevents the flow of asphalt applied to the porous top layers of the substrate from penetrating the bottom surface. This eliminates the need for fines to prevent sticking of shingles in a shingle stack. In addition, substrate layers that combine fiberglass and polyester fibers in various configurations provide a substrate that can be used in typical shingle manufacturing and manufacturing of waterproofing products that is impact resistant.

Abstract: The present invention provides a novel, floating, offshore wind turbine (FOWT) structure, referred to as a yawing buoy mast (YBM) structure. The YBM platform vertically combines a submerged spar buoy with outrigger legs and a mast on which a wind turbine nacelle is mounted. Compared to a conventional spar buoy wind turbine, weight is significantly reduced by optimizing how loads are borne and reacted by the floating structure. The mass of the YBM platform is reduced relative to the energy captured by the turbine resulting in a reduction in the cost of energy (COE). Platform load dynamics are coupled with the dynamics of the wind turbine by integration of the YBM platform and turbine controllers.

Abstract: Apparatus and methods for providing fluid such as water at a controlled temperature. In some embodiments, hot and cold fluid is provided to a thermostatically controlled mixing valve, which then provides fluid at a mixed temperature to a plumbing system. The thermostat provides a first loop for closed-loop control of fluid exit temperature, and preferably there is a second, electronically controlled closed loop for adjusting the temperature of fluid exiting the valve. In yet other embodiments the electronic control loop is fail-fixed, such that a loss of electrical communication to the actuator results in the actuator maintaining its last position. In yet other embodiments there is a system including a flow sensor and a recirculation pump such that the temperature of the fluid exiting the valve cannot be adjusted if there is insufficient flow, or if the pump is actuated.
