Title: Method of regeneration of medicago sativa and expressing foreign dna in same
Inventor: BUISING CHARISSE M
IPC: C12N15/82
Filed: 1992-12-02
Granted: 2004-04-13
Abstract: The invention relates to improved transformation and regeneration of alfalfa, Medicago sativa. A method is used to transform alfalfa by using particle acceleration.      Optimum results with mature cotyledons occurs when bombarding after 24 to 120 hours of imbibing water.      Regeneration and transformation of alfalfa is greatly improved by using immature cotyledons or embryos of immature cotyledons for transformation and regeneration. Immature cotyledons include those up to about 25 days past pollination, and preferably include cotyledons excised at 10-15 days past pollination, most preferably including those excised at about 10 days past pollination. These cotyledons have a light green to translucent appearance. Plants resulting from bombardment of somatic embryos of immature cotyledons retain regeneration ability.

Title: Fluid mixing apparatus and method of mixing
Inventor: RICCIARDI RONALD J
IPC: B01F27/74
Filed: 1992-09-09
Granted: 1996-06-25
Abstract: A mixing apparatus for mixing two or more fluids into a homogeneous mixture.  A rotor (62) is mounted on a drive shaft (56) coaxially within a cylindrical casing (2).  Bores (88) run the length of the rotor.  Mixing conduits (90) lead from the bores (88) to outside the rotor (62). A cylindrical sleeve (42) with slots (92) is mounted coaxially within the casing (2) and encloses the rotor (62). The fluids to be mixed are introduced into one end of the casing (2) within the sleeve (42) while the rotor (62) is rotating. The fluids are sheared as they enter into the bores.  The combined fluid either passes out of the mixing conduits (90) near the front of the casing where it is sheared again or passes further along the bore to exit mixing conduits (90) near the rear of the casing. The fluid then passes through the slots (92) in the sleeve (42), where it is sheared again.  Finally, the mixed fluid exits the other end of the casing.

Title: Magnesium oxychloride cement compositions and methods for manufacture and use
Inventor: ALLEY RUSSELL I
IPC: C04B28/32
Filed: 1991-04-02
Granted: 2001-06-12
Abstract: Magnesium oxychloride cement compostions, products, and uses thereof, are provided by mixing a magnesium oxide com-position, a magnesium chloride brine solution, and aggregate particles. The cement compositions are adapted for use in repairing damaged concrete surfaces, casting both functional and decorative forms, and coating surfaces with stucco. The addition of a small amount of acid may be added to the cement composition to promote a more complete cementing reaction. The resulting ce-ment product exhibits substantially increased strength and water resistance.  Brine from the Great Salt Lake is a preferable source of the magnesium chloride brine solution. Brine from the Great Salt Lake, which contains various mineral impurities, results in a cement composition substantially stronger than cement produced from a pure magnesium chloride brine solution.

Title: Block transform coder for arbitrarily shaped image segments
Inventor: CHEN HOMER H
IPC: H04N7/30
Filed: 1994-05-31
Granted: 1999-06-29
Abstract: The present invention is directed at a Transform Coder Unit (TCU) to transform an arbitrarily shaped image into optimal transform coefficients (OTC) for data transmission.  The TCU comprises a forward transform which transforms the image to transform coefficients, and a TCS generator which generates a transform coefficient set (TCS) from the transform coefficients.  The TCU also contains an inverse transform which transforms the TCS to a computed region block having computed pel values. Finally, the TCU comprises a replacer which replaces those computed pel values corresponding to the interior pel set with the original pel values to form a modified computed region block which is re-iterated until optimal transform coefficients are determined.     The present invention is also directed at a process for determining optimal transform coefficients using the aforementioned device.

Abstract: A method for controlling operation of a galvanneal induction furnace includes the steps of providing a steel strip having a molten zinc coating applied thereto and transporting the strip to an induction furnace in which the strip and coating are to be alloyed. The temperature which the strip is estimated to attain just prior to entering the furnace is then calculated. A temperature which the strip should achieve during the alloying reaction is then selected. The power which must be applied to the furnace to elevate the strip temperature from the estimated temperature to the alloying temperature is then calculated. Power is then supplied to the furnace.
