Abstract: Disclosed is a trash collector for drainage channels. The trash collector includes a main frame provided with engaged parts engaged with engaging protrusions of an inlet of a drainage channel and a penetration part having one side vertically penetrated, an opening and closing plate mounted in the penetration part so as to selectively open and close the penetration part depending on a load of water introduced through the inlet of the drainage channel, and a hinge shaft interposed between the main frame and the opening and closing plate so as to axially rotate the opening and closing plate. A base plate of the main frame and the opening and closing plate have a designated height so that fallen leaves and road trash accumulated and gathered on the base plate and the opening and closing plate may be sufficiently suctioned by suction force of a street cleaning vehicle.

Abstract: The present invention relates to a contact lens for presbyopia and, more specifically, to a contact lens for presbyopia, providing both a far-distance vision area and a near-distance vision area in one contact lens, and continuously forming a lens magnification of the far-distance vision area and the near-distance vision area of the dominant eye and the non-dominant eye while changing the sizes of the far-distance vision area and the near-distance vision area of two eyes according to the dominant eye and the non-dominant eye, such that an intermediate-distance area is partially overlapped, thereby continuously providing a near-distance vision area at a far distance by a neural summation phenomenon that selects a clearly visible image in both eyes.

Abstract: An improved pistonless cylinder, including both single acting and double acting configurations, based on an Aramid fiber reinforced elastomer tubular which is highly stiff in radial direction against radial expansion and elastic in axial extension, so as to form a completely sealed, extendable and retractable pressure chamber and to be able to perform as well as, or better than, most of the conventional hydraulic cylinders in terms of load bearing capacities, maximum stroke distances and service durability. This improved cylinder employs no piston, piston rod, sealing seals or oil based hydraulic fluid, and utilizes non-metal materials to construct the majority of the parts for its extendable and retractable pressure chamber; therefore, this new cylinder can achieve significant weight and fabrication cost reduction. In addition, this new pistonless cylinder uses ordinary liquids, e.g., fresh water or seawater, as its hydraulic fluid, and can work directly as a hydraulic or pneumatic cylinder interchangeably without a need for much, if any, modification.

Abstract: A general purpose passive annular grout seal assembly is disclosed which is suitable both for offshore jacket installations with regular annular gap sizes and for offshore wind turbine structure installations with an extraordinarily large annular gap of any sizes. Grout self-sealing operation during grouting is conducted in two steps: 1) a gap reducing action enabled by a gravity differential pressure force induced tilting of a plurality of flip plates, and 2) a gravity differential pressure force induced sealing action for the remaining small gaps. This disclosed new type of grout seal can not only enhance grout seals' overall system reliability by eliminating all potential sources for harmful results known to the offshore industry, but also significantly reduce costs for fabrication, transportation, and installation of grout seals.
