Abstract: An ecological fiber roll element for use in protecting a shoreline to prevent erosion and to the protected shoreline. The roll element comprises a generally cylindrical roll, with or without aquatic plants therein, the roll element consisting essentially of coir material. The roll element includes a netting material about the exterior surface of the roll. A plurality of the roll elements are arranged on a shoreline and secured usually by stakes to the shoreline.

Abstract: A system for remediating groundwater contaminated with radionuclides, consisting of an underground bed of crushed zeolites. Distribution pipes convey contaminated groundwater to the zeolite bed by means of a pump, which draws the contaminated water through wells from an underground plume of released waste mixed with groundwater. The radionuclides in the water undergo ion exchange with the zeolite minerals, and lock into the zeolite crystal lattice. After the contaminated water passes through the zeolite bed, it is collected by a series of collection pipes and conveyed to a sampling station, where it can be determined whether the water has been decontaminated sufficiently to discharge it by piping to a river outfall or back to the ground. When functioning, the system contains the released contaminants on the waste site and prevents further spread and migration of the contaminated water by means of the cone of depression created by the pumping well.

Abstract: A packaging kit for the immobilization of an article to be shipped, which kit comprises a base sheet of selected width and length sufficient to hold the article being packaged, the base sheet characterized by a horizontal fold line extending substantially across the base sheet, which permits the base portion to be folded inwardly to receive an article to be packaged on the base sheet. The sheet has a pair of spaced-apart opposite end portions having two or three parallel spaced-apart fold lines perpendicular to the horizontal central fold line, the fold lines adapted to move the end portions between a generally flat position and a folded V-shape or Z-shape position. The base sheet has at least two pairs of spaced-apart aligned notches on either side of the base portion.

Abstract: An integral system and method for the separation and purification in a single operation of a heat or oxygen-sensitive liquid feed, such as a plant derived liquid feed mixture of fatty acids, tocopherol compounds and sterols, into a low boiling point purified fraction of Vitamin E tocopherol compounds and a high boiling point concentrate fraction of triglycerides, which system can be maintained in the presence of an inert gas to provide reduced degradation and increased purity of the Vitamin E fraction. The system includes a pre-evaporator, a vapor-liquid separator, a packed bed distillation column, a rotary thin film evaporator and an evaporator-stripper.

Abstract: A sports board, particularly a body board, for surfing purposes, which board is a preformed, preshaped foam board composed of closed-cell foam material, with an inner core of low density foam material and an outer core of foam material of greater density than the inner core. The board has a top and bottom surface and two sides, the sides containing outwardly extending angular side rails thereon, extending from one to the other end of the board, and around the front of the board. The board includes an integral thermoplastic polymer film material heat-laminated only to the bottom surface of the board, and to the lower side rail surface of the board. The polymer film material provides a low-frictional bottom surface and lower side rail surface and provides for enhanced mechanical stiffening of the board.

Abstract: An integral collector-distributor device including chimney hats and adapted for use in a gas-liquid exchange column to promote radial mixing of a liquid on a distributor tray surface. The collector-distributor device includes a tray having a tray surface adapted to extend generally horizontally across the cross-sectional area of the column to collect downwardly flowing liquid. A plurality of gas risers on the tray permit the upward movement of an upwardly flowing gas through the tray, and a plurality of liquid distributors permit the generally uniform distribution of the collected downwardly flowing liquid to a lower section of the column.

Abstract: The invention relates to a revetment and a revetment system and method for the protection of the banks of water courses, canals, flowing and still water bodies or the like. The revetment consists of chambers with a net-like encasement on all sides, filled with particulate substrate material and bound together into a single unit.

Abstract: An injection molding apparatus method and system for molding a plastic article having inward or outward projections on the exterior surface. The injection mold has a first and second mold part adapted to move between a closed, molding position and an open, article-recovering position and which defines a mold cavity for an article to be molded. The first expandable cavity mold part has a base with an opening therethrough and a plurality of outwardly tapered arms extending from the base to an open end that extends into the mold cavity where it is held in place by a striker plate during the injection molding process. The second inner mandrel mold part has a one and other end adapted to move reciprocally and longitudinally within the base and arms of the expandable cavity element, the top end threaded to form the interior threaded surface of the injection molded article.

Abstract: An inexpensive, compact, portable, retractable cord, visual indicator, electrical/telephone connector-type surge protector, which comprises a housing composed of a molded plastic, with two female receiving grounding inlets on its upper surface, a visual indicator light, and a pair of female telephone inlets on one side. On another side, the housing has two openings for a retractable electrical extension cord and a retractable telephone cord. On the opposite side of the housing are two independent, retaining, on-off switches for the two cords. The housing is composed of two sections, an upper and lower section, with an inner spring coil mechanism on two independent reels in each section for the electrical and telephone cords respectively. The invention is designed to be used with standard electrical apparatus or other sensitive electrical devices, which are to be protected from electrical surges, where extension cords may be required, and allows for the retraction of the cords when not required.
