Abstract: Genes encoding Class II EPSPS enzymes are disclosed. The genes are useful in producing transformed bacteria and plants which are tolerant to glyphosate herbicide. Class II EPSPS genes share little homology with known, Class I EPSPS genes, and do not hybridize to probes from Class I EPSPS's. The Class II EPSPS enzymes are characterized by being more kinetically efficient than Class I EPSPS's in the presence of glyphosate. Plants transformed with Class II EPSPS genes are also disclosed as weU as a method for selectively controlling weeds in a planted transgenic crop field.

Abstract: The time to grind a workpiece can be reduced by selecting a grinding wheel whose width is not substantially greater than wheel strength considerations require, and which may therefore be less than the axial length of the region to be ground providing a work rest or work steady to increase the workpiece stiffness if required, and performing a succession of plunge grinding steps so as to grind the whole of the said axial region. Typically the grinding wheel is an electroplated CBN wheel, and the width of the grinding wheel selected is the narrowest permissible given the desired feed rate and motive power available.

Abstract: In a collapsible roof mounting for orienting a satellite dish system from below, an upper channel-shaped formation arranged to present a dish-shaped component adjacent one end and an arm formation for the feed horn intermediately thereof and nestable within and interconnected to a lower channel-shaped formation adjacent the other end for swinging movement thereabove, a tubular shaft formation supporting the lower channel-shaped formation centrally thereof from below for rotation about a substantially upright axis, a displaceable linkage including a worm gear interconnected to the upper channel-shaped formation and a worm extending axially of the tubular shaft formation for swinging the upper channel-shaped formation upwardly from the nested disposition and reversely, a handle formation for the tubular shaft formation below the roof for imparting rotation thereto and a crank for the worm located below the handle formation for imparting displacement to the worm and worm gear.

Abstract: A method of supplying both an oxygen steelmaking process and an ironmaking process with oxygen. The oxygen is separated from air by rectification of the air. A first stream of oxygen from the rectification to the steelmaking process. A second stream of oxygen is also supplied from the rectification to the ironmaking process. The first and second streams of oxygen are both withdrawn from essentially the same stage of the rectification and both contain from about 97 to about 98% by volume of oxygen and less than about 100 parts per million of nitrogen.

Abstract: Genes and methods for optimizing levels of substrates employed in the biosynthesis of copolymers of 3-hydroxybutyrate (3HB) and 3-hydroxyvalerate (3HV) in plants and bacteria via manipulation of normal metabolic pathways using recombinant DNA techniques are provided. This is achieved through the use of a variety of wild-type and/or deregulated enzymes involved in the biosynthesis of aspartate family amino acids, and wild-type or deregulated forms of enzymes, such as threonine deaminase, involved in the conversion of threonine to P(3HB-co-3HV) copolymer endproduct. By these methods, enhanced levels of threonine, .alpha.-ketobutyrate, propionate, propionyl-CoA, .beta.-ketovaleryl-CoA, and .beta.-hydroxyvaleryl-CoA are produced. Also provided are methods for the biological production of P(3HB-co-3HV) copolymers in plants and bacteria utilizing propionyl-CoA produced through a variety of engineered metabolic pathways. Introduction into plants and bacteria of an appropriate .beta.-ketothiolase, .beta.

Abstract: The repair method includes removing eroded or damaged trailing edge portions of partitions in the diaphragm of a turbine, over 50% of the length of the partitions being removed commencing at the trailing edge. A coupon which is a precise replication of a portion of an originally specified partition is welded to the remaining or extant partition portion by a seal weld along the radial length of the coupon on the suction side of the repaired partition and two full penetration welds at the ends of the coupon to secure it to the inner and outer rings or side walls of the diaphragm. The repaired partition is thus substantially identically contoured as the original partition.

Abstract: In a mainframe class data processing system having multiple partitions and a port to a network, a table is established. The table defines communications paths between the port to the network and at least two partitions of the multiple partitions. More specifically, each partition has at least one application executing therewithin and the communications paths are defined thereto. Data frames are passed between the network and the applications within the partitions through the port to the network and along the communications paths defined in the table such that network communications is effected.

Abstract: A holographic data storage system includes a laser (12) for generating both data and reference beams. The reference beam is deflected by an optic system such that the reference beam can be directed at the surface of a thin holographic storage media (10) to interfere with a data beam to store data in the form of an interference grating. For each Bragg angle associated with a reference beam and a data beam, multiple pages of information are stored in the storage media (10). Each page of information stored at a given Bragg angle is associated with a different Bragg plane. Upon reconstruction of the data, a given reference beam at a given Bragg angle will reconstruct the data in the associated Bragg plane on a detector (42) and will reconstruct data for the same Bragg angle but a different Bragg plane in an off-image plane (88) or (90). This, therefore, allows multiple pages of information to be stored for the same Bragg angle in the same storage region (54).

Abstract: Air is raised in pressure by a compressor and pre-purified by removal of impurities, particularly H.sub.2 O vapor and CO.sub.2, in an adsorption unit. The resulting air is cooled in a heat exchanger, and is subjected to a first rectification in a rectification column in which the air is separated into a nitrogen-rich fraction and an oxygen-rich fraction. A further oxygen fraction enriched in argon is subjected to a second rectification in which argon is separated from oxygen in a second rectification column. First and second argon products of different purity are withdrawn from the second rectification column through outlets thereof.

Abstract: A self-operable knee therapy device includes a first elongate platform on which the lower leg of a person may be secured so that the back of the leg is in contact with the platform, a second elongate platform pivotally joined at one end to an end of the first platform and on which the upper leg of the person may be secured with the back of the upper leg being in contact with the second platform, and an elongate central support member pivotally joined at its upper end to the joined ends of the first and second platforms for supporting the joined ends in an elevated position. A handle is coupled to the first platform to enable grasping by a user so that when the handle is moved away from the person, the free end of the first platform is caused to pivot downwardly, and when the handle is moved toward the person, the free end is caused to pivot upwardly.
