Maize event DP-098140-6 and compositions and methods for the identification and/or detection thereof
Patent number: 7928296Abstract: Compositions and methods related to transgenic glyphosate/ALS inhibitor-tolerant maize plants are provided. Specifically, the present invention provides maize plants having a DP-098140-6 event which imparts tolerance to glyphosate and at least one ALS-inhibiting herbicide. The maize plant harboring the DP-098140-6 event at the recited chromosomal location comprises genomic/transgene junctions having at least the polynucleotide sequence of SEQ ID NO:5 and/or 6. The characterization of the genomic insertion site of the DP-098140-6 event provides for an enhanced breeding efficiency and enables the use of molecular markers to track the transgene insert in the breeding populations and progeny thereof. Various methods and compositions for the identification, detection, and use of the maize DP-098140-6 events are provided.Type: GrantFiled: October 10, 2007Date of Patent: April 19, 2011Assignees: Pioneer Hi-Bred International, Inc., E.I.

Patent number: 5513508Abstract: An apparatus for inflating inflatable articles, such as bicycle tire inner tubes, and for securing mobile articles, such as bicycles, to other objects. In one preferred embodiment, a first length of cable and a second length of cable are kept within a housing until needed to secure the article to an object. A cable holding sleeve holds the lengths of cable in a substantially side-by-side relationship when the cables are within the housing. When needed, the lengths of cable are withdrawn from the housing, passed through the frame of the article, around the object and the two ends of the cables are locked together by way of, for example, a cylindrical combination lock. When the first and second lengths of cable are unlocked, a constant tension spring, provided in some embodiments, retracts the lengths of cable back into the housing. Other embodiments of the invention are provided with a pump piston at the end of the lengths of cable which remain within the housing.Type: GrantFiled: October 25, 1993Date of Patent: May 7, 1996Assignee: Paradigm Products, Inc.Inventors: Richard G. Saunders, Wayne E. Saunders, Raymond C. Saunders, David W. Saunders
