ALEXANDRIA, Va., April 23 -- The following federal patents were awarded to inventors in Kentucky.
Koch Agronomic Services Assigned Patent
ALEXANDRIA, Va., April 23 -- Koch Agronomic Services, Wichita, Kan., has been assigned a patent (8,419,819) developed by Allen R. Sutton, Corydon, Ky., for a solid urea fertilizer.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A solid urea fertilizer prepared by mixing a solid, flowable, urea formaldehyde polymer with a urea source, such as molten or solid urea to form a fertilizer that has favorable crush strength characteristics, low biuret content, and/or desirable storage and handling properties. The urea fertilizer may contain additionally, an aqueous urea formaldehyde solution or mixture. Optionally, the fertilizer may contain a urease inhibitor and/or a nitrification inhibitor."
The patent application was filed on June 22, 2007 (11/821,322). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,419,819&OS=8,419,819&RS=8,419,819

General Electric Assigned Patent for Heat Recovery System for Use with a Washing Appliance
ALEXANDRIA, Va., April 23 -- General Electric, Schenectady, N.Y., has been assigned a patent (8,419,865) developed by Ronald Scott Tarr, Louisville, Ky., and Rajesh Narayan Kulkarni, Karnataka, India, for a "heat recovery system for use with a washing appliance."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A heat recovery system for use with a washing appliance having a tub includes a heat exchanger having a first tube and a second tube extending through the first tube such that the first tube and the second tube are substantially concentric. A first end connector is configured to couple to a first end portion of the first tube and a first end portion of the second tube. The first end connector is formed as one-piece and includes a first connection portion configured to couple in flow communication with the first tube, and a second connection portion configured to couple in flow communication with the second tube."
The patent application was filed on May 11, 2011 (13/105,556). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,419,865&OS=8,419,865&RS=8,419,865

Ethicon Endo-Surgery Assigned Patent for Tissue Retrieval Device with Reinforced Pouch and Variable Volume
ALEXANDRIA, Va., April 23 -- Ethicon Endo-Surgery, Cincinnati, has been assigned a patent (8,419,749) developed by four co-inventors for a "tissue retrieval device with reinforced pouch and variable volume." The co-inventors are Frederick E. Shelton IV, Hillsboro, Ohio, Shailendra K. Parihar, Mason, Ohio, Michael S. Cropper, Edgewood, Ky., and Christopher W. Widenhouse, Clarksville, Ohio.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A tissue retrieval device includes a tubular member, one or more frame members, and a tissue retrieval bag. The tubular member is insertable into a patient through a trocar to open the bag within the patient to receive a tissue specimen. The internal capacity provided by the bag may vary based on the longitudinal position of the frame members. The bag may be stretchable to increase its internal capacity. At least one sidewall of the bag may include one or more reinforcement members, which may influence the way in which the bag stretches by restricting stretching of the bag in one or more directions while freely permitting stretching of the bag in one or more other directions. Part of the undeployed bag may be contained in a recess formed in the side of the tubular member, with a removable cap being positionable over the undeployed bag and recess."
The patent application was filed on Jan. 26, 2010 (12/693,498). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,419,749&OS=8,419,749&RS=8,419,749

Ethicon Endo-Surgery Assigned Patent for Ultrasonic End Effectors with Increased Active Length
ALEXANDRIA, Va., April 23 -- Ethicon Endo-Surgery, Cincinnati, has been assigned a patent (8,419,756) developed by four co-inventors for an "ultrasonic end effectors with increased active length." The co-inventors are Foster B. Stulen, Mason, Ohio, Kevin L. Houser, Springboro, Ohio, Vincent P. Battaglia Jr., Lebanon, Ohio, and Brian D. Bertke, Fort Thomas, Ky.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "An end effector includes a first portion having a first specific acoustic impedance value, and a second portion having a second specific acoustic impedance value less than the first specific acoustic impedance value. The first portion includes a proximal end segment of the end effector and a distal end segment of the end effector, and the proximal end segment and the distal end segment are composed of a first material. The second portion includes an insert segment of the end effector composed of a second material. The insert segment is located between the proximal end segment and the distal end segment along the longitudinal axis of the end effector. The insert segment functions to bridge or fill the nodal energy gap. A surgical instrument includes a transducer configured to produce vibrations along a longitudinal axis as a predetermined frequency. An ultrasonic blade extends along the longitudinal axis coupled to the transducer. An insert segment or a pad is positioned adjacent to the blade such that it engages the blade when the surgical instrument is in a closed position and generates heat filling the nodal energy gap."
The patent application was filed on July 27, 2007 (11/881,662). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,419,756&OS=8,419,756&RS=8,419,756
