Abstract: The present invention discloses functional and selectable micro-Ti plasmids. The hygromycin phosphotransferase (aphIV) gene from Escherichia coli was inserted between the 5' promoter and associated amino terminal region-encoding sequence of an octopine synthetase gene and the 3' terminator signal sequence of a nopaline synthetase gene. These constructs were assembled between T-DNA border fragments in a broad-host-range vector and used to create antibiotic-resistant plant cells.

Abstract: V12.1:15694/ERC         Abstract of the Invention Axially-extending troughs in a bark of an internally threaded collar receive setting balls of a driver that apply a torque to the collar through the balls bearing on the walls of the troughs.  At a predetermined pre-load, the balls fail the bark and plow through it to develop circumferential furrows, and the torque application on the collar ends.  A second torquing with balls at a different axial position fails the bark again at the same pre-load to compensate for any relaxation after the first torque application.

Abstract: ABSTRACT      In the continuous cooking of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, the material is subjected to a minimum of mechanical action, especially under high temperature and pressure conditions, so as to increase the quality of the pulp.  Also, even for large digesters the uniformity of treatment is enhanced, and scaling may be reduced while energy efficiency is increased.  Material is fed without significant steaming to a feeder screw within a perforated cylinder mounted at the bottom of an impregnation vessel.  The material flows upwardly in the impregnation vessel, with screens adjacent the top of the vessel thickening the slurry before it is discharged into the top of a continuous digester. The discharge from the impregnation vessel to the continuous digester is made with a minimum of mechanical action on the pulp.  The impregnation vessel may be disposed within, and concentric with, the digester, or it may located exteriorly of the digester and supply more than one digester.  Conduits mounted on the exterior of the impregnation vessel, when concentric with the digester, can supply treatment liquid at various locations along the height of the digester.
