Abstract: A wire fencing material comprises parallel line and fill wires extending respectively lengthwise and widthwise. The line and fill wires are secured to one another by welding at cross over locations, and at selected locations and between adjacent fill wires, the line wires have segments projecting alternately from opposite sides of the fencing to thereby define sleeves configured and dimensioned to axially receive support posts.

Abstract: A method for annealing and galvanizing wires which comprises induction heating the wires in a first chamber at a first higher temperature to anneal the wires, cooling the wires to a second lower temperature in a second chamber and galvanizing the wires in a third chamber. The chambers are in serial communication and the heating, cooling and galvanizing steps are effected in an oxygen free atmosphere.

Abstract: An aquaculture cage including a buoyant upper support for disposition at the surface of a water body; a side wall having an upper edge secured to said upper support so as to project below the surface of the water body, the side wall being formed with a plurality of vertically contractible, non-buoyant panels having vertically adjacent edges joined to form an enclosure and each of the joined vertical edges defining a plurality of vertically spaced apart loops; and an elongated connector element extending through the loops of the adjacent edges so as to secure together the panels. Also included is a bottom wall joined to the side wall to close the bottom of the enclosure.

Abstract: A high security fence and post assembly including a T-section post for installation in the ground and having an elongated, upwardly extending first plate portion defining a front surface and a rear surface and an elongated second plate portion projecting transversely from a longitudinally extending section of the rear surface.

Abstract: A flood flow modulator system including a dam positioned across a watercourse so as to restrict water flow therein and thereby create a retained water body; the dam having an upstream surface facing the water body, an oppositely directed downstream surface, and a top surface joining the upstream and downstream surfaces. Defined by the dam is a slot having substantially vertical side surfaces and a substantially horizontal bottom surface. A gate is pivotally mounted in the slot for movement between a substantially vertical closed position and a substantially horizontal open position; the gate being U-shaped in section and having a front wall with edges disposed adjacent to the side and bottom surfaces so as to substantially close the slot when in the closed position, and sidewalls projecting transversely from the front wall toward the water body and each closely adjacent to a different one of the side surfaces.

Abstract: An aquaculture system including an upper support for disposition at the surface of a water body of an aquaculture farm; a cage having a side wall portion and a bottom wall portion, the side wall portion having an upper edge secured to the upper support so as to project below the surface of the water body and the side wall portion being formed out of vertically contractible, non-buoyant mesh; and a lower support disposed between a bottom edge of the side wall portion and an outer edge of the bottom wall portion.

Abstract: A container including a plurality of wire mesh wall panels having substantially planar sides and arranged to form an enclosure, adjacent panels having juxtaposed panel edges attached along a plurality of joints, a panel edge attached along at least some of the joints having wire ends forming loops each projecting through a mesh interstice a given distance beyond one planar side of an adjacent planar panel and each loop having a reentrant terminal portion extending back through the mesh interstice beyond an opposite planar side of the adjacent panel. Attaching the reentrant terminal portions on the opposite planar side of the adjacent panel is a retainer wire and a latch link extends through the loops on the one side of the adjacent panel.
