Abstract: Apparatus and methods are provided for a fluid fertilizer distributor (10, 200, 300, or 400) for distributing fluid fertilizer conducted from a supply vessel (11) to each of a plurality of applicator lines (44). The fluid distributor may regulate a fluid fertilizer flow rate by selectively moving a flow restrictor (50, 250, 350, or 450) relative to the distributor housing. The distributor housing may include a supply inlet port (12, 212, 312, or 412) and a plurality of distributor outlet ports (16, 216, 316, or 416) each for fluid communication with a respective one of the plurality of applicator lines (44). The fluid distributor may separate the fluid fertilizer into a plurality of fluid flow paths prior to reducing the pressure in the fluid to avoid gas flashing or vaporization prior to separation. Thereby, fluid distribution may be effected upon a substantially liquid fluid within the fluid distributor, which may result in substantially uniform fertilizer application, with reduced rate variation between applicator lines. The flow restrictor (50, 250, 350, or 450) may be substantially ring shaped and positioned on an external surface of the distributor housing, or substantially cylindrical shaped and positioned substantially internal to the distributor housing. The fluid distributor may provide for substantially infinitely regulating the application rate between a fully closed position and a fully open position. Rate regulation may be performed manually or by programmable controller.

Abstract: The present invention provides a flexible bag comprising at least one sheet of flexible sheet material assembled to form a semi-enclosed container having an opening defined by a periphery. The opening defines an opening plane, and the bag has an upper region adjacent to the opening and a lower region below the upper region. The upper region has a preferential elongation axis perpendicular to the opening plane which permits the upper region to expand in response to an externally-applied force upon the bag, while the lower region has a preferential elongation axis parallel to the opening plane which permits the lower region to expand in response to forces exerted by contents within the bag to provide an increase in volume of said bag. The bag therefore exhibits increased stability in use and is easier to close.

Granted: 2006-10-03
Abstract: A Mach-Zehnder electro-optic modulator is formed that exhibits significantly reduced chirp by utilizing an RF electrode that covers a first waveguide arm in a first region of the modulator and covers the second, remaining waveguide arm in a third region of the modulator (with a second, intermediate region used as a transition area for the electrode). Moving the electrode from one waveguide to the other allows for the chirp created in the third region to essentially "null out" the chirp that accumulated along the first region. Modulation of the optical signal is maintained in the presence of the "electrode switching" by inverting the domain of the optical substrate material in the third region of the modulator.

Title: Soybean oil process
Inventor: TYSINGER JERRY E
IPC: C11B1/00
Filed: 2002-04-23
Granted: 2011-08-09
Abstract: A solvent extraction free, caustic refining free, process for producing refined soybean oil from soybeans is described in which soybeans, offer cleaning, cracking and dehulling, are crushed in less than 60 seconds while heating the soybeans to a frictionally generated temperature of from about 300°F to about 370°F. Free fatty acids are then removed through physical refining, instead of previously employed caustic refining, since the low level of nonhydratable phospholipids does not create undesirable flavors during the physical refining process. The resultant oil exhibits a significantly greater frylife that non-hydrogenated soybean oil produced by solvent extraction and caustic refining.

Granted: 2008-12-02
Abstract: There is disclosed herein a systematic, computationally-efficient, two-stage method for determining well locations in a 3D reservoir model while satisfying various constraints including:  minimum interwell spacing, maximum well length, angular limits for deviated completions, and minimum distance from reservoir and fluid boundaries. In the first stage, the wells are placed assuming that the wells can only be vertical. In the second stage, these vertical wells are examined for optimized horizontal and deviated completions. This solution is expedient, yet systematic, and it provides a good first-pass set of well locations and configurations. The first stage solution formulates the well placement problem as a binary integer programming (BIP) problem which uses a "set-packing" approach that exploits the problem structure, strengthens the optimization formulation, and reduces the problem size. Commercial software packages are readily available for solving BIP  problems. The second stage sequentially considers the selected vertical completions to determine well trajectories that connect maximum reservoir pay values while honoring configuration constraints including: completion spacing constraints, angular deviation constraints, and maximum length constraints. The parameter to be optimized in both stages is a tortuosity-adjusted reservoir "quality".  The quality is preferably a static measure based on a proxy value such as porosity, net pay, permeability, permeability-thickness, or pore volume. These property volumes are generated by standard techniques of seismic data analysis and interpretation, geology and petrophysical interpretation and mapping, and well testing from existing wells. An algorithm is disclosed for calculating the tortuosity-adjusted quality values.
