Abstract: A water channel is disclosed. The water channel has a channel body defining a flow passage having an entrance, an exit, and defining a flow direction from the entrance to the exit. Intake deflectors are positioned at the entrance and are angled away from the flow direction relative to the channel body and positioned to direct a flow of water into the entrance of the channel body. Outlet deflectors are positioned at the exit of the channel body and extend away from the exit of the channel body. The outlet deflectors are angled away from the flow direction relative to the channel body.

Abstract: A modular pipe and a method of installing the pipe uses a first pipe section positioned in end to end relation with a second pipe section, the first and second pipe sections being precast from a cement-based material, wherein each pipe section has an outer surface, a flow passage, a first end, and a second end. Each end has a connection profile, an axis, and an end face that is perpendicular to the axis. A collar surrounds and secures the connection between adjacent ends. The collar is constructed from a plurality of collar elements. Each collar element overlaps the pipe connection and engages the connection profile along a portion of the perimeter of each of the first end of the second pipe section and the second end of the first pipe section.

Abstract: There is provided a multi-sided culvert having a base section, a first side body, and a second side body. The first and second side bodies are engaged at the top of the culvert by a top engagement and supported by the base section. The base section engages the first side body by a first bottom engagement and the second side body by a second bottom engagement. The first part of the first bottom engagement has a first guide section and a first interlocking section, and the second part of the first bottom engagement has a second guide section and a second interlocking section. During installation the first and second guide sections guide the first and second interlocking sections into engagement, the first and second interlocking sections having tapered surfaces that, when engaged, permit upward and outward movement of the second part relative to the base.

Abstract: A water turbine includes a base and an axle extending upwardly relative to the base. A body is provided having an axle receiving bore positioned along a longitudinal rotational axis. The axle is positioned in the axle receiving bore, such that the body rotates about the longitudinal rotational axis. A weight bearing roller assembly is positioned between a lower end of the body and the base to facilitate the body rotating relative to the base. Vanes extend radially from the body, such that flowing water striking the vanes imparts a rotational force to the body.

Abstract: A method for reducing loudspeaker magnitude and/or phase distortion, in which one or more filters pertaining to one or more drive units is automatically generated or modified based on the response of each specific drive unit. The drive unit response may be determined by electromechanical modelling of the drive unit. Drive unit models may be enhanced by electromechanical and/or acoustic measurement such that the resulting filter becomes specific to each specific drive unit.

Abstract: A method of building a structure in the presence of water includes providing two or more three-sided elongated triangular bodies that has a first end, a second end, and an internal flow passage that extends between the first end and the second end. Each of the triangular bodies has an apex with a base opposed to the apex. Each of the triangular bodies is positioned in side by side relation, with the flow passage of one or more of the triangular bodies serving as a flow path for water. A road, a bridge or a dock is positioned transversely across the triangular bodies.

Abstract: A system and method for rapidly responding to and regaining control of uncontrolled flow from offshore hydrocarbon wells, that includes a subsea containment assembly, optionally including a capture caisson assembly installed around the assembly, riser systems for production of hydrocarbons to capture vessels on the surface of the sea, and modularized subsystems facilitating communication between and fluid flow from the subsea containment assembly through the riser to the capture vessel.

Abstract: A ground engaging tool system comprises a ground engaging tool such as a tip, an adapter mounted to or part of a work tool, and a rotating lock member. The ground engaging tool is attached to the adapter, and a post portion of the adapter slides into a slot provided on the lock. The lock is rotated so that the entrance to the slot is blocked and the post cannot slide out of the slot. The lock in this position is in a locking position, and the retention of the post in the slot of the lock retains the ground engaging tool to the adapter.
