In a system for sucking and discharging a solution from a vessel (micro-plate assembly 6) by suction nozzles 2, processes for suction, discharge, separation, etc. can be carried out with use of a simple mechanism, including suction nozzle moving means 3 for positioning the respective distal ends of the suction nozzles on the inner wall surface of the vessel, magnetic particle holding means 4 for magnetic particles 7 in a given position in the vessel, and solution discharge means 5 for sucking ou...

Device for draining water from at least one gutter of a retractable vehicle roof, characterized in that the intermediate conduit (9), which is linked to the movement of the moving roof, is attached by its upstream part (9A) to the drain (8) and linked by its downstream part (9B) to the drainage conduit (10) by a nesting joint (11), so that when the moving roof moves into the stowed position, this downstream part (9B) is denested so as to break the continuity, and vice versa when the mobile roof ...

A drainage mop has a handle unit and a drainage unit. A rotary unit is disposed between the handle unit and the drainage unit so that the handle unit can be bent with respect to the drainage unit. In bending state, the rotary unit drives a driven unit so that the water absorbing unit of the drainage unit is squeeze radially to drain water out. Thus, in draining or cleaning, the operations of the water absorbing unit can be executed easily and conveniently.

A drainage structure having perforated parallel top and bottom plates separated by spacer members. A web joins adjacent spacer members and has a curved profile such that water spilling over the web does so, at a varying velocity profile to increase oxygenation of the water. This drainage structure can also be filled with good drainage soil and planted with grass to filter and retain water that passes therethrough, with a layer of filter medium below and a water permeable drain below the filter m...

This invention relates to a drainage system for providing drainage above and below a poured floor. After the sub-soil layer is prepared to receive a poured floor thereover, a conduit is provided in the sub-soil and a floor drain is connected to the conduit. The floor drain has first aperture means opening upwardly and second aperture means opening substantially laterally at a location below the first aperture means. On top of the sub-soil layer there is then provided a relatively liquid-permeabl...

A one-piece drainage channel for surface drainage is disclosed that comprises a molded, elongate body, in particular made of concrete polymer, with an upper surface over which vehicles can travel and which comprises inlet openings that open into a channel compartment, with side walls and a floor and with end faces to which can be connected additional drainage channels, catch pits or similar drainage installations, wherein the channel compartment comprises adjoining boundary surfaces, in particul...

The machine for making the drainage elements employs a forming collar about the delivery chute for the aggregate so as to form a continuously supplied strip of netting into a tube to receive the aggregate. The machine may be run on an automatic basis without a need to stop the machine in order to replenish the supply of netting. A pair of tapes are used to secure the longitudinal edges of the tape together, one tape located inside the tube and the other tape located outside the tube.

A catheter includes a tubular body, a ring member, and at least one elongate member. The tubular body has a distal region. The ring member encircles at least a portion of the circumference of the tubular member. The one elongate member has a proximal end and a distal end, the distal end of the elongate member being coupled to the distal region of the tubular body and the proximal end being attached to the ring member. Forming a loop in a distal end of a catheter includes pulling a ring that enci...

A drainage bag for receiving bodily waste, such as an ostomy bag, comprises an outer bag of material soluble in cold water, e.g. polyvinyl alcohol, and an inner bag of material insoluble in water at ambient temperature and body temperature but soluble in organic solvent, e.g. 2-oxepanone polymer (polycaprolactone). When the bag (and contents) are to be disposed of, appropriate organic solvent (e.g. benzyl alcohol) is applied to the inner bag. The bag can then be placed in a WC bowl and is flusha...

Drainage under a deck can be performed by a structure that includes hanging components and corrugated panels. For example, a hanging component can have connected first and second portions, with the first portion being connected to hang from one of the joists and extending downward to where it connects to the second portion, which is below the joist. The second portion can be connected to support of at least one of the panels from above. The upper surfaces of panels are sloped so that drainage oc...
