Abstract: This invention relates in part to plant breeding and herbicide tolerant plants. This invention includes a novel aad-1 transformation event in corn plants comprising a polynucleotide sequence, as described herein, inserted into a specific site within the genome of a corn cell. In some embodiments, said event/polynucleotide sequence can be “stacked” with other traits, including, for example, other herbicide tolerance gene(s) and/or insect-inhibitory proteins. Additionally, the subject invention provides assays for detecting the presence of the subject event in a sample (of corn grain, for example). The assays can be based on the DNA sequence of the recombinant construct, inserted into the corn genome, and on the genomic sequences flanking the insertion site. Kits and conditions useful in conducting the assays are also provided. The subject invention also includes related methods of controlling weeds.

Abstract: Disclosed is a system for treating waste water. The system may be applied to any application for the treatment of waste water which benefits from an equalized flow into the waste water treatment processes, such as industrial batch discharges, storm water settling and screening, and septic receiving at a waste water treatment plant. The system comprises a single primary settling tank for the processes of grit removal, flow equalization, fine screening and primary clarification. The system further comprises the use of a flow measurement device on the discharge side of the primary settling tank to provide a uniform flow to downstream processes. The system further comprises placement of a fine screen on a discharge mechanism which controls the effluent flow from the primary settling tank.

Abstract: The subject invention provides novel plants that are not only resistant to 2,4-D and other phenoxy auxin herbicides, but also to aryloxyphenoxypropionate herbicides. Heretofore, there was no expectation or suggestion that a plant with both of these advantageous properties could be produced by the introduction of a single gene. The subject invention also includes plants that produce one or more enzymes of the subject invention alone or “stacked” together with another herbicide resistance gene, preferably a glyphosate resistance gene, so as to provide broader and more robust weed control, increased treatment flexibility, and improved herbicide resistance management options. More specifically, preferred enzymes and genes for use according to the subject invention are referred to herein as AAD (aryloxyalkanoate dioxygenase) genes and proteins. No ?-ketoglutarate-dependent dioxygenase enzyme has previously been reported to have the ability to degrade herbicides of different chemical classes and modes of action.

Abstract: A driven decanter assembly for a wastewater primary treatment system, comprising a longitudinal decanter disposable in the wastewater and having a longitudinal trough and a horizontal entrance weir, a polygonal or arcuate screen attached to the decanter and having at least two screen surfaces disposable below the surface of the wastewater outside of the trough, and a floating baffle pivotably mounted to the decanter and disposable in the wastewater outside of the screen. The driven decanter assembly can directly replace a prior art driven decanter in any waste water primary treatment system.

Abstract: An influent feed system for directing the influent liquid via hydraulic energy to scour the surface of primary treatment tank walls and base to move the scoured solids to a sludge trough. Scouring action takes place during periods of low liquid levels in the tank. The system comprises two identical, adjacent tanks sharing a common distribution box. Either or both of the tanks are in use at any given time. The tank in use will be empty occasionally each day. Influent feed troughs disposed transversely in each tank directs solids towards a sludge hopper in the tank bottom. The IFTs extend over the width of the tank to provide scouring of the entire end wall and floor surface. Each IFT has a sump with a valved discharge piped directly to the sludge trough, and the floor of each IFT is sloped towards the sump to facilitates draining of solids.

Abstract: Axial flow fan propellers are provided with a roughened portion along the trailing edge of the fan blades on the pressure side of the blade to minimize tonal acoustic emissions generated by laminar boundary layer vortex shedding. The roughened portion may be provided by trip surfaces formed in the blades, by strips of abrasive material adhered to the blades along the trailing edges, respectively, by parallel or cross-hatched serrations in the blades or by upturned or offset trailing edges of the blades. The height of the roughened portion should be about equal to the boundary layer thickness of air flowing over the blade surfaces during operation of the fan. The fan propellers are particularly advantageous in heat exchanger applications, such as residential air conditioning system condenser units.

Abstract: Birds are moved through chilled water by bird moving means such as an auger or by a series of paddles. The birds tend to accumulate in a predetermined path in the water. Streams of water that include an antibacterial additive are directed toward the predetermined path and engage and disperse the birds, and wash the birds with the streams of water and the antibacterial additive, thereby increasing the rate of heat transfer from the birds and increasing the effectiveness of the antibacterial properties of the agents in the chilled water.

Abstract: The chiller includes a semi-cylindrical tank (36) that conforms to the perimeter of its auger (38) SO that the water can be raised to a water level (68) high above the auger shaft (44). Streams of water (84) are directed from the pulling side (80) across the lower portion of the tank beneath the auger shaft (44) to the dead side 82 of the tank at intervals along the tank so as to disperse the lower portion of the masses (23) of buoyant birds (22) from the more crowded pulling side (80) of the tank, beneath the auger shaft (44) toward the more vacant dead side (82) of the tank, thereby distributing the products more evenly throughout the tank and causing more water turbulence in the tank, thereby increasing the rate of heat transfer from the birds and avoiding having the birds cross over the auger shaft moving backward in chiller into a following flight of the auger.

Abstract: A system and method for isolating data messages received from subscribers in a CATV system are disclosed. The system includes a spectrum parallel router which receives data messages in the return spectrum of a service line at a service site. A switch at the service site directs data messages to service lines coupled to the site which have destination addresses corresponding to one of the service lines. Data messages not having a destination address corresponding to one of the service lines are provided to a transmitter for transmission to the next higher level of the CATV network over a return cable. Each service site has its own return cable which may be coupled to a distribution hub or a headend.

Abstract: In an auger-type product chiller having an auger including a series of successive flights that form a generally helical structure that, when rotated, moves product through cold water for chilling the product, control elements extending from faces of the flights at a non-zero angle. The control structures prevent "clumping" and packing of poultry product, break up any "clumps" and packs of the product that may develop, and improve product uniformity. In this manner, the advantages of proper agitation, as well as rapid, predictable and even product cooling and moisture introduction, are achieved. Implementations of the control elements include sets of rods extending from the flights at 30.degree. angles from radial lines of affixation to the flights, flat plates extending from the flights at 30.degree. angles from radial lines of affixation to the flights, and sets of rods extending between successive flights near peripheries of the flights.

Abstract: An ultrasonic, transcutaneous blood flow detector. A protective mounting cup is positionable against the skin of a patient for the transfer of ultrasonic energy into and out of the patient's body. The detector utilizes only a single piezoelectric transducer with a first face in juxtaposition with an interior face of the cup. A film of viscous semifluid material is positioned between the transducer first face and the cup's interior face to couple ultrasonic energy between the transducer and the cup. A resilient spring or foam member resiliently biases the transducer first face into engagement with the cup's interior face with the semifluid material therebetween, thus permitting substantially uninhibited deformation of the transducer in response to a drive signal.

Abstract: For removal of the contaminant deposits from a surface such as a tube sheet of a vertical tube heat exchanger, as in a nuclear steam generator, having plural spaced heat exchange tubes connected to the tube sheet, a lance is radially moved along the tube sheet between parallel rows of tubes. The lance carries a nozzle for ejecting a stream of high pressure cleaning fluid toward the sludge deposits, the nozzle acting cyclically to sweep the stream throughout a range of directions centered about the nozzle axis. The nozzle may include diverting streams for deflecting the cleaning fluid stream, with the diverting streams either being generated by a fluidic oscillator or being fed back from the outlet portion of the nozzle. Alternatively, pivoting vane means may be provided in the nozzle to divert the cleaning fluid stream.
