Abstract: A toilet assembly includes a flush engine having a bowl defining a sump and a trapway extending from the sump. A bowl insert is configured to be located in the bowl and a shroud is configured to be positioned over the flush engine to conceal at least a portion of the flush engine.

Abstract: A method for decontaminating a tube includes positioning an antenna at least partially within the tube. The tube is positioned at least partially within a living body. The method also includes decontaminating the tube by causing the antenna to emit electromagnetic waves having a frequency from about 10 GHz to about 100 GHz for a time duration that is less than or equal to 60 seconds. The electromagnetic waves cause a temperature of the living body proximate to the tube to increase from about 0.1° C. to about 3° C. so as to not substantially damage the living body.

Abstract: The present invention relates to an in-line mixing apparatus and use therein for adding a polymer solution and dewatering an aqueous mineral suspension. Said method comprises statically mixing the aqueous mineral suspension with a poly(ethylene oxide) (co)polymer to form a dough-like material. The viscous mixture material is then dynamically mixed in an in-line reactor to reduce the mixture viscosity and to form microflocs and release water. Said method is particularly useful for the treatment of suspensions of particulate material, especially waste mineral slurries, especially for the treatment of tailings and other waste material resulting from mineral processing, in particular, the processing of oil sands tailings.

Abstract: A system for decontaminating a tube includes a signal generator configured to generate a signal. The system also includes an antenna configured to receive the signal from the signal generator. The antenna is configured to be inserted at least partially into a tube that is positioned at least partially within a body. In response to receiving the signal from the signal generator, the antenna emits electromagnetic waves that at least partially decontaminate the tube. The electromagnetic waves have a frequency from about 10 GHz to about 100 GHz. The electromagnetic waves cause a temperature of the body proximate to the tube to increase less than about 3° C. over a time duration that is up to 40 seconds.

Abstract: The present invention relates to a method for flocculating and dewatering oil sands fine tailings. Said method comprises mixing the aqueous mineral suspension with a poly(ethylene oxide) (co)polymer to form a dough-like material. The material is then dynamically mixed in an in-line reactor to break down the dough-like material to form microflocs having an average size of 1 to 500 microns, and to release water. The internal diameter of the in-line reactor is at most five times the internal diameter of the inlet pipe of the reactor. The suspension of microflocs has a viscosity of at most 1000 cP and a yield stress of at most 300 Pa.

Abstract: A gas diffuser including a grid of aeration pipes spaced apart and in parallel alignment within a horizontal plane is provided. The aeration pipes have improved discharge hole placement along their lengths and around their circumferences to provide improved performance and reduced fouling of membrane filtration systems associated therewith.

Abstract: A gas diffuser comprises a grid of aeration pipes spaced apart and in parallel alignment with each other within a common horizontal plane and a manifold in fluid communication with the aeration pipes. A given aeration pipe (12) includes: a length (L) extending between two ends and defining an axis (Z), a hydrodynamic diameter (Dh),an elliptical cross-sectional area defining a vertical plane comprising a vertical (Y) and horizontal (X) axis intersecting through a center (C) which are perpendicular to axis (Z), an outer circumference defined by a first arc (20) comprising 30° located below the (X) axis and bisected by the (Y) axis, and a second arc (22) comprising 330° which is non-overlapping with the first arc (20.
