| 20110220732 | FINE BUBBLE AIRLIFT DEVICE - The present invention relates to an aeration device for use in a liquid medium. The device includes a housing adapted to float within the medium such that a top portion thereof remains above a top surface of the medium. The housing has a bottom portion and an open side portion. The device further includes a hose affixed to the bottom portion of the housing substantially parallel to the surface of the liquid medium. The hose has a wall with a plurality of pores formed therein. The device further includes a gas-supplying pipe affixed to the hose and means for supplying a gas to the pipe such that the gas passes through the pipe and into the hose. | 09-15-2011 |
| 20110198764 | AERATION SYSTEM WITH ANTIMICROBIAL PROPERTIES - Aeration pipe for diffusion of a gas into a liquid medium, the pipe having a flexible microporous tubular wall of thermoset polymer particles and a thermoplastic binder for melt bonding said thermoset polymer particles and dispersing an antimicrobial compound substantially uniformly throughout the wall. The aeration pipe is useful in various environments such as aquaculture and waste water treatment. | 08-18-2011 |
| 20110101681 | COUPLING MEMBER WITH INTERRUPTED THREAD AND METHOD OF MANUFACTURE - Coupling assembly for use in conduits or tubing holding a pressurized liquid, such as a garden hose. The structure provided facilitates uncoupling of male and female fittings in such an assembly which substantially reduces the uncontrolled release of pressure in the system such that the pressurized liquid will not flow uncontrollably from the assembly during decoupling. Methods are provided for making and using such components that result in one or more of an ease of manufacture, reduced material costs, reduced machining costs, and/or ease of use. | 05-05-2011 |
