Title: Creating altered floral morphology in transgenic plants and uses therefor
Inventor: MA HONG
IPC: A01H5/00
Filed: 1993-09-30
Abstract: ABSTRACT OF THE DISCLOSURE       CREATING ALTERED FLORAL MORPHOLOGY IN TRANSGENIC             PLANTS AND USES THEREFOR       The present invention relates to transgenic plants in which floral development is altered, particularly plants in which petal number is increased (i.e., petal number is greater than in the corresponding naturally-occurring or wild type plant) or otherwise altered, as in plants which are sterile.  Transgenic plants of the present invention contain DNA which encodes all or a portion of a protein essential for floral development and when present in plant cells, results in altered floral development, particularly enhanced floral development (e.g., increased petal number) and/or sterile plants.  The present invention also relates to methods of producing plants with altered floral development, exogenous DNA sequences whose presence in a plant results in altered floral development and vectors or constructs which include DNA useful for producing recombinant plants with altered floral development.  Seeds produced by plants which contain exogenous DNA encoding a protein which is required for floral development, such as AG DNA in the sense orientation or exogenous DNA which has been altered in such a manner that it encodes an altered form of a protein required for floral development, such as altered AG DNA, are also the subject of the present invention.

Title: Single use hypodermic safety syringe
Inventor: JORE MATTHEW B
IPC: A61M5/31
Filed: 1994-03-14
Abstract: ABSTRACT      The present invention relates to a disposable medical syringe which has a hollow plunger to receive a used inoculation needle.  The syringe has a hollow syringe barrel, open on one end and closed on the other.  A hollow plunger assembly, which extends out the open end of the syringe barrel, has a hollow tube with a fixed seal attached at one end. At the other end of the plunger assembly, a needle holder is sized to slide within the hollow tube.  The sliding seal and needle holder are biased toward each other by a stretched, resilient tube that has a fluid passageway passing through the sliding seal, resilient tube, and needle holder.  The needle holder is normally locked at one end of the plunger assembly by a locking means.  As the syringe is collapsed, the syringe barrel trips the locking means to permit the needle holder, and attached inoculation needle, to be retracted into the hollow tube. The three components--inoculation needle, hollow tube, and syringe barrel--are telescoped together by this action to compact the throw-away unit with the used inoculation needle resting in a position protected by the double outer walls.

Title: Method for determining cytolytic t cell precursors
Inventor: COULIE PIERRE G
IPC: C12Q1/02
Filed: 1993-01-07
Abstract: The invention relates to a method for determining precursors of cytolytic T cells and the frequency of these precursors, where the cytolytic T cells which develop therefrom are specific to antigens associated with or characteristic of the tumors. The method involves contacting peripheral blood monocyte cells (PBMC) containing sample to a source of antigen characteristic of or associated with the tumor, such as non viable tumor cells. The PBMCs, if precursors are contained therein, react and cytolytic T cells develop. These can then be determined by assaying for lysis of tumor cells introduced to the mixture. The methodology can be used for monitoring patient response to various therapeutic regimes.

Title: Rod guide with wear gauge
Inventor: BERTAGNOLLI JOHN T
IPC: E21B17/00
Filed: 1995-01-11
Abstract: A rod guide in the form of a substantially star-shaped body molded in intimate contact with a sucker rod includes a plurality of blades, vanes, or fins projecting from the body to define a smoothly continuous concave surface of the body. At least one of the vanes has formed therein an indentation that provides a gauge of rod guide wear. The ends of the blades form knife blades to reduce resistance to fluid flow about and through the rod guide and to reduce turbulent flow behind each blade. The disclosed structure offers increased strength against bending moment subjected to the rod guide, thereby increasing resistance to bending fracture and tensile elongation. This structure also increases erodable volume of rod guide material while maintaining flow about and through the rod guide. The wear gauge of the present invention may also be included on solid, cylindrical rod guides.
