Irrigation and drainage based on hydrodynamic unsaturated fluid flow
InactiveUS6918404B2Improve the level ofHigh porosityPipeline systemsMachines/enginesEnvironmental engineeringPorous microstructure
Irrigation and drainage systems are disclosed, including a saturated zone and at least one pipe in communication with the saturated zone. The pipe(s) can be configured to comprise a tubarc porous microstructure for conducting water from the saturated zone to an unsaturated zone in order to drain the water from the saturated zone. The water can be delivered from the saturated zone to the unsaturated zone through the tubarc porous microstructure, thereby permitting the water to be harnessed for irrigation or drainage through the hydrodynamic movement of the water from one zone of saturation or unsaturation to another.

Rotatable and pivotable connector
A rotatable, pivotable connector having a female end, a male end, a neck joining the male and female ends, and an exterior retention element. The exterior retention element, such as, for example, a fitting, may limit expansion of the exterior of the female end. The exterior retention element may also take the form of a retainer or similar structure to retain a fitting about the exterior of the female end of the connector. Further, the connector may be hollow, thus defining a continuous passage within. Also, multiple connectors may be interconnected to form an arm.

Lens delivery system
A lens delivery system having a plunger, an injector body and a nozzle portion connected to the injector body, the nozzle portion having a hinged lid and a hollow body with a lens holding platform formed beneath the hinged lid. The cartridge has an elongated nozzle tube or tip with a bore, the bore communicating with the lens holding platform. The bottom of the bore is rounded, which causes the edges of the lens between the lens haptics to fold upwardly as the lens is pushed down the bore from the platform by the plunger. A removable pin fits into the lid and prevents the lens from moving down the bore of the tip during shipment and storage.

Pipe joint
ActiveUS7464970B2Improve assembly efficiencyPossible to selectPipe couplingsCouplingsEngineeringFlange
A pipe joint for connecting a rigid pipe with a retaining flange to a tube includes a pipe joint body formed with a through bore and a window in communication with the bore. A tube connector portion may be connected at an angle to a rigid pipe connector portion. A pipe retainer provided with locking pieces can be located in two positions relative to the pipe joint body. The first position allows the retaining flange to pass through the locking pieces. The second position retains the rear of the retaining flange and prevents inadvertent removal of the rigid pipe. The retaining pieces engage the rear of the flange through the window communicating with the bore. The locking direction of the retainer can be altered relative to the tube connector portion to suit different applications and ease assembly.

Elbow fitting with step feature for pneumatic transport system
ActiveUS7300074B1Lower energy requirementsReduce resistanceBulk conveyorsSiphonsTransport systemEngineering
An elbow fitting is used in a pneumatic product conveying system in which the fitting expands from the inlet pipe along the outer side of the elbow fitting to enable a layer of accumulated product particles to be formed so as to move at a lower velocity than the velocity of the incoming product stream while establishing a moving contact surface for deflecting incoming product particles toward the outlet pipe with a minimum of pressure resistance and product attrition. The accumulated product particles are discharged from the elbow fitting by incorporating a step in the outer surface of the elbow fitting to create a Bernoulli effect causing the accumulated product particles to enter the air flow after the incoming flow of product particles has ceased. The particles in the accumulated layer are replenished from the incoming flow during operation of the elbow fitting.

A fuel system having an ecology valve controlling liquid flow through a retention passage when pressurized liquid is passed through the valve is presented. The retention passage winds between the valve outlet and a cavity such that no matter which way the valve is oriented gravity alone is unable to drain liquid from the cavity to the outlet.
