Abstract: A multi-use reusable tubular barrier to be placed along the edges of construction sites to contain debris formed of a woven mesh material body carrying particulated fill within a medial chamber defined by the body. Tabs carrying grommets at opposing end portions of the body and spacedly arrayed about an outer surface of the body allow secure releasable interconnection with adjacent bodies in a variety of alignments.

Abstract: A space saving anchor point for a concrete deck or column. The anchor point includes an external rigid member that attaches to the elongated receiver box and becomes embedded into the concrete. The external rigid member may be a T-shaped bracket with an elongated main flange and two parallel side flanges or two L-shaped brackets each with a main flange and a perpendicularly aligned side flange. Formed between the two side flanges on the T-bracket is a center space that receives an elongated receiver box. The elongated box is a partially enclosed structure with a lower opening that communicates with an interior cavity. Extending between the side flanges and transversely through the interior cavity is a rod with its opposite ends that extend laterally from the sides of the side flanges and become covered with concrete. Attached to the portion of the rod located inside the elongated box's interior cavity is an elongated connector plate.

Abstract: A space saving anchor point for a concrete deck or column. The anchor point includes an elongated receiver box attached to the inside surface of a form used to construct a concrete structure that becomes embedded the concrete deck. The elongated box is a partially enclosed structure with a lower opening that communicates with an interior cavity. The elongated box includes optional flange surfaces that attached to the inside surface of a form used to construct the concrete deck. Extending transversely through the interior cavity is a rod with its opposite ends that extend laterally from the sides of the elongated box and become covered with concrete. Attached to the portion of the rod located inside the interior cavity is an elongated connector plate. The connector plate is assembled on the rod and is configured to rotate around the rod and move longitudinally inward inside the interior cavity to hidden position or moved outward from the interior cavity partially exposing the plates' second opening.

Abstract: A ceiling anchor point and anchor point system for a concrete deck. The anchor point includes a receiver box attached to the form used to construct a concrete deck that becomes embedded the concrete deck. The receiver box is a partially enclosed structure with a lower slot opening that communicates with an interior cavity. The receiver box includes flange surfaces that attached to the inside surface of a form used to construct the concrete deck. Extending transversely through the interior cavity is a rod with its opposite ends that extend laterally from the sides of the receiver box and become covered with concrete. Attached to the portion of the rod located inside the interior cavity is an elongated connector plate. The connector plate is assembled on the rod and is configured to rotate around the rod and nests entirely inside the receive box or extend downward through the slot opening.

Abstract: An anchor point and method for creating an anchor point in a metal composite deck. The anchor point is made by inserting a connector plate into a slot opening formed in the metal corrugated panel used to make a metal composite deck. The connector plate is a flat, elongated bar with two opposite ends. Formed on the upper end is a first opening designed to receive a structural rebar or an ancillary rebar member attached to the-structural rebar that becomes imbedded into the composite deck. Formed on the lower end of the connector plate is a second opening designed to connect to a suitable D-ring connector plate or clip used by a construction worker when working under the deck and installing fixtures to the bottom surface of the metal composite deck.

Abstract: A method of concentrating microorganisms, particularly pathogenic microorganisms, from food and/or water potentially contaminated by dilute densities of the organisms is described. Potentially contaminated water or fluid food is directed along an elongated flow path which rests generally within a plane perpendicular to an axis of rotation, and is subjected to centrifugal forces by rotating the flow path about the rotational axis. The method may be executed by use of a conventional continuous flow channel-type blood plasmapheresis centrifuge.

Potentially contaminated water is directed along an elongated flow path which rests generally within a plane perpendicular to an axis of rotation, and is subjected to centrifugal forces by rotating the flow path about the rotational axis. The method may be executed by use of a conventional continuous flow channel-type blood plasmapheresis centrifuge. The method has been tested for its capability for recovering pathogenic protozoan parasites such as Cryptosporidium and Giardia from contaminated water, and recovery rates of up to 100% have been observed.

Abstract: A method of concentrating oocysts of waterborne protozoan parasites from water potentially contaminated by dilute densities of the parasites is described. Potentially contaminated water is fed into the separation channel of a continuous separation channel centrifuge. The water is centrifuged for a period of time sufficient to collect the parasitic oocysts and cysts in the channel.
