Abstract: A downpipe fitting for coupling between top and bottom ends of a downpipe. The downpipe fitting includes two parts connected together and rotatable relative to one another about a longitudinal axis thereof. The first part has an inlet, sized and shaped to couple with an outlet of a first section of the downpipe, above the downpipe fitting. The second part has an outlet which is sized and shaped to couple with an inlet of a second section of the downpipe, below the downpipe fitting. The inlet and outlet of the fitting define a flow path for rainwater therethrough. Rotation of the second section of downpipe below the downpipe fitting, about the longitudinal axis, is decoupled from the first section of downpipe above the downpipe fitting.

Abstract: Prophylactic devices that have a flexible sheath, and an annular retainer portion with an adhesive surface to adhere to the skin and keep the device in place. The sheath is closed at the distal end and has an opening at a proximal end. The retainer portion is connected to the sheath at the proximal end, and surrounds the opening of the sheath. The adhesive surface may be formed by an adhesive substance or other means and may seal all or part of the retainer portion against the skin. The retainer portion may conform to the skin and/or have molded features. One embodiment includes backing and cover layers which adhere to the device to form a protective pouch or package which contains the sheath and lubricants on the sheath.

Abstract: Methods and systems for treating oil sands tailings streams at an elevated pH using lime are disclosed herein. In some embodiments, the method comprises providing a tailings stream including 10-55% solids by total weight, increasing the pH of the tailings stream by combining the tailings stream with lime to produce a lime-tailings mixture having a pH of at least 11.0, and dewatering the lime-tailings mixture to produce a first stream having 10% or less solids by total weight and a second stream having 50% or more solids by total weight. The first stream can correspond to a release water stream, and the second stream can correspond to a cake. The lime slurry can include about 10% lime by total weight, and can comprise lime hydrate, quicklime, or a combination thereof. Dewatering the lime-tailings mixture can include routing the lime-tailings mixture to a centrifuge unit and/or a pressure or vacuum filtration unit.

Abstract: The present invention provides a wind turbine with two overlapping wing shaped turbine blades mounted about a rotational axis. The wing shaped turbine blades are shaped so that wind from an outer surface of a first leading wing shaped turbine blade flows into an inner surface of a trailing wing shaped turbine blade.
