Abstract: A pole with an eyelet disposed at one end and the first and second group of furled cup shaped furled containers are connected along the longitudinal length of the pole. The pole with the containers is inserted into a substance. The substance may, if desired, be sand, mud or mud-like soil. If desired, the insertion process may be accomplished by forcing the pole into the substance by applying downward force on the eyelet or twisting the pole in a clockwise direction into the substance. Once the pole is inserted into the substance the pole may, if desired, be twisted in the counterclockwise direction to unfurl the cup shaped containers. To extract the pole, the pole is twisted in the clockwise direction closing the cup shaped containers and pulling the pole in the vertical direction.

Abstract: A water treatment device that chemically treats tidal water. The water may, if desired, be salt water or fresh water. The water treatment device is substantially cylindrical with paddles extending outward from central hubs. The paddles are T-shaped and are perforated. The perforation aids in water treatment by aerating the water as the tide movement turns the paddles. The water treatment device has a central perforated tray that is slidably insertable into the central hubs. The central hubs are open in the center to permit the aerated water from the paddles to come in contact with the water treatment chemicals in the central tray. The perforations of the central tray allow the water treatment chemicals to come into contact with the surrounding area to treat the tidal water.

Abstract: The present invention provides a container and method for storing a solution containing a labile species comprising storing said solution in a flexible, optically transparent container comprised of an ethylene vinyl alcohol copolymer having an oxygen permeability of less than 0.2 cc/100 in2/24 hrs.

Abstract: The present invention provides a receptacle (30) for a therapeutic fluid susceptible to deterioration on exposure to a gas such as oxygen or carbon dioxide. The receptacle (30) has walls of sheet material each including at least one layer forming a barrier essentially impermeable to such gas, and a seal sealing the walls together in a region thereof. A transfer tube (40) is sealed in the seal having a proximal end in the receptacle (30), a distal end accessible from outside the receptacle (30), a flow passage (56) extending between said proximal and distal ends, and a closure (54) blocking flow through the flow passage (56) adapted to be pierced by a tubular needle for transfer of therapeutic through the needle. The transfer tube (40) and closure (54) are essentially impermeable to said gas.

Abstract: A tool for dropping one or more balls and then one or more darts features a closable ball drop opening that works automatically after the ball release to minimize damage to the subsequently released dart. A retainer keeps the darts from coming back up above the dart launcher in the event of a pressure surge in the well. The dart launcher features a dedicated movable barrel for each dart that can be locked in a fully misaligned and fully aligned position with the casing or tubular. A handle is retained to the dart housing and can be manipulated to defeat the lock and rotate a given barrel. The darts may be inspected in their respective barrels before launch and the launch order is variable.

Abstract: Tools for expanding downhole tubulars into each other or in open hole are disclosed. One embodiment uses a movable cone biased by Bellville washers to move longitudinally against such bias and allow collets to move radially in or out to a predetermined maximum diameter. A release system allows collet retraction to avoid hang up on removal. In an alternate embodiment, more suitable for open hole applications, pressurized gas pushes a movable cone longitudinally against the collets. A stationary cone is on the opposite side of the collets from the movable cone. The collet rides out or in between the cones and raises the gas pressure when forced in. A pressure actuated release allows the lower cone to shift downwardly to allow the collets to retract for removal.

Abstract: This invention relates to in vitro cell culture employing a fibrin network in a flexible gas permeable container. Specifically, the invention is directed to a cell culture container comprising a flexible, gas permeable material with fibrin matrix which is conducive to the culture of anchorage dependent cells, and the container is suitable for use in closed system in vitro cell culture. The gas permeability of the container is sufficient to permit cellular respiration.

Abstract: A method of processing blood establishes communication between a donor and a blood flow path and pumps whole blood from the donor into a container through the blood flow path. The method centrifugally separates the whole blood in the container into concentrated red blood cells and a plasma constituent. After the method interrupts communication between the donor and the blood flow path, the method pumps the concentrated red blood cells from the container to mix the concentrated red blood cells with a nutritive solution to restore the hematocrit of the concentrated red blood cells to a desired value. The method also removes the plasma constituent.

Abstract: A system and method of separation of therapeutic components from blood. The system includes a dual member centrifuge and a disposable single use fluid transfer set. The set includes an elongated flexible separation chamber having an input port, a separated component output port and a residual fluid output port. The input port and the separated component output ports are located at opposite ends of the elongated separation chamber. The centrifuge includes a receiving chamber with a selectively formed annular slot therein. The separation chamber is positioned in the annularly shaped slot and rotated at a predetermined rotational velocity. Fluids such as whole blood flows through the separation chamber and are separated into various therapeutic components such as platelet rich plasma and residual concentrated red blood cells. Platelet rich plasma can be drawn off as the separated therapeutic component. An alternate two part transfer set provides for highly efficient platelet pheresis.

Abstract: Methods of separating selected blood components separate blood by centrifugation in a rotating chamber into a first separated blood component, a residual blood fluid, and an interface between the first separated blood component and the residual blood fluid. The methods withdraw the first separated blood component out of the rotating chamber through a first outlet port, and withdraw the residual blood fluid out of the rotating chamber through a second outlet port. During the separation step, the methods accumulate a second separated blood component in the interface without withdrawal from the rotating chamber by controlling the position of the interface within the rotating chamber at a location spaced away from flow communication with both the first and second outlet ports.
