摘要:
The invention concerns a hollow body of plastic material, in particular a fuel tank, which was obtained by extrusion blow molding, having at least one line which is stationarily laid in its interior, wherein the hollow body is distinguished in that the line is at least region-wise joined in material bonded relationship to the inside wall of the hollow body.

A pump intake apparatus for directing fluid flow to a pump. The pump intake assembly includes a pump intake column having a pump bell and a pump intake pit. The intake pit includes an upper intake pit encircling the pump intake column and has a tapered inner surface providing the upper intake pit with a decreasing cross-sectional area to accelerate the fluid flow toward the pump bell. The upper intake pit may include at least one vane extending inwardly from the inner surface of the upper intake pit to suppress rotation of a fluid flowing through the upper intake pit. The intake pit further includes a lower intake pit floor positioned substantially below the pump bell and including a projection member upwardly extending from a central region of the lower intake pit floor toward the pump bell. The lower intake pit floor has a substantially curvilinear surface interconnecting the upper intake pit to the projection member to redirect and accelerate fluid flow toward the pump bell. The intake assembly may include a shroud extending from the lower end of the pump intake column to also facilitate acceleration of fluid flow toward the bell portion of the pump. A method of using the pump intake is also disclosed.

An automotive fuel tank storage system includes a fuel storage tank installed in a vehicle and a barrier fluid tank containing a supply of barrier fluid. A distribution system connected with the barrier fluid tank and with the fuel storage tank distributes barrier fluid about the outer periphery of the fuel contained within the storage tank in the event of a collision event, creating a boundary layer of more viscous fluid which inhibits exfiltration of the fuel from the fuel storage tank.

The invention provides a system and method for filling a reservoir through one or a plurality of inlet nozzles to encourage mixing. The inlet nozzles include a specifically designed size reduction between the main line or branch to which the inlet nozzle is attached and the nozzle pipe itself; a specifically designed nozzle pipe length which, combined with the pressure increase provided by the size reduction, will produce the most appropriate jet flow; and a specifically designed location and orientation of the inlet nozzle within the reservoir. These parameters produce a developed turbulent jet flow which, when the inlet nozzle is positioned at the appropriate elevation and oriented in the appropriate direction(s), will direct the developed turbulent jet flow with the appropriate momentum to reach the surface of the water with initial major mixing taking place in this area. A corresponding draining system and method is also disclosed.

Apparatus for managing layers of different density includes an enclosed tank for holding the liquids so that they stratify into separate layers of different levels in the tank. A conduit for liquid in the tank is open at an inner end to the tank interior, and is open at an outer end to the tank exterior. A drive moves the inner end of the conduit to different levels within tank so liquid can be transferred into or out of different levels in the tank.
摘要:
A method and apparatus for separating ferrous metal particles from non-ferrous metal particles suspended in a liquid, such as a coolant from a machining operation, in which mixed particle containing liquid is discharged across a horizontal, non-magnetic separating surface; the magnetic ferrous metal particles are captured by a magnetic force exerted by an array of parallel magnets disposed underneath the separating surface, the non-magnetic non-ferrous metal particles are washed by the liquid into a collecting flume from where they can be passed to a filtering station for removal from the liquid, and the captured ferrous metal particles are scraped from the separating surface and conveyed to a ferrous metal discharge by a scraper conveyor which moves transversely to the discharge direction of the liquid.

A planar extensible structure in a flat planar flex circuit can be extended out of the plane of the circuit by a distance of more than the width of the structure to carry fluids, electrical signals or optical signals into and out of the circuit. The planar extensible structure may be an Archimedes spiral, a parabolic spiral, a polygonal spiral, a non-spiral extensible shape, or other extensible shape. The invention can be used to siphon fluid samples from each well in a multiple-well microtiter plate into a microfluidic manifold for utility in chemical and biochemical analysis. The invention can also be used to allow electrical interconnect between adjacent circuits or circuit boards, and can allow signals carried in optical fibers to be transferred between optical circuits in different planes.
摘要:
A liquid gathering and transferring apparatus for gathering liquid from a liquid source containing a quantity of liquid having a liquid surface and containing debris and discharging the liquid into a liquid receiving location includes an intake chamber having a chamber discharge end in fluid communication with the liquid receiving location and a chamber structural end opposite the chamber discharge end and a chamber side wall extending between the chamber discharge end and the chamber structural end and a longitudinal series of liquid intake ports in the chamber side wall extending generally between the chamber discharge end and the chamber structural end, the intake ports being of generally increasing diameter along the chamber side wall toward the chamber structural end for minimizing liquid vortex formation at the intake ports; so that the intake chamber can be suspended below the liquid surface at a minimal depth where less debris is present and draw liquid with negligible vortex formation.
摘要:
A valve for use with a liner bag for a container, and a liner bag including a valve, the valve including a valve member located in a valve seat and having a valve opening for egress of liquids from the liner bag. An operating lever is positioned outside the liner bag. A protective cage extends in front of the valve opening, the cage being positioned inside the liner bag to prevent the wall of the liner bag from collapsing into the valve opening during emptying of liquids from the liner bag. A flange may extend around the valve seat to retain the valve in the wall of the liner bag. This arrangement prevents the liner bag wall from clogging the valve during discharge of the bag's contents.

Systems and methods for dispensing an anti-traction, mobility denial material on a target surface. In various exemplary embodiments, a method of dispensing an anti-traction material on a target surface includes providing a polymer particle powder to a first section of a dispensing nozzle, providing a water stream to a second section of a dispensing nozzle, and mixing the polymer particle powder with the water stream upon exit of the streams out of the first and second sections of the dispensing nozzle to form the anti-traction material on the target surface, the formed anti-traction material being a gel.
