Title: Expression of herbicide tolerance genes in plant plastids
Inventor: MCBRIDE KEVIN E
IPC: C12N15/09
Filed: 1999-07-10
Abstract: Provided are constructs and methods for expressing herbicide tolerance genes in plastids of plant cells. Constructs include the components of a promoter functional in a plant plastid, a DNA sequence which is capable of conferring tolerance in a plant cell to at least one herbicide compound when said DNA sequence is transcribed in plastids of said plant cell and a transcription termination region. Herbicide tolerance is produced by transforming plastids with the constructs of the invention and growing plant cells comprising the transformed plastids under conditions wherein the DNA sequence is transcribed and plant plastids and cells containing the plastids are rendered tolerant to applications of at least one herbicide compound.

Inventor: NAKAMURA HIROYUKI
IPC: H03H9/145
Filed: 2000-05-31
Abstract: A SAW filter comprising a piezoelectric substrate and at least two filter tracks formed on the substrate, each having at least two IDT electrodes for input and output. The two filter tracks have substantially the same phase within a pass band, while it is substantially inverse-phased outside the pass band. For realizing the above-described conditions, input IDT electrode of one filter track is connected in parallel with input IDT electrode of the other filter track, while output IDT electrode of one filter track is connected in parallel with output IDT electrode of the other filter track. Furthermore, frequency values of said two filter tracks substantially coincide at a point 3dB lower from the peak transfer function value. Thus the above-configured SAW filter of the present invention is smaller in the overall size and offers a broad pass band and a steep attenuation characteristic.

Inventor: EMTER JAMES SR
IPC: B23C5/08
Filed: 2001-03-19
Abstract: A tool for use in an abrading or resurfacing machine includes a head portion, a shank portion and a base portion, the shank portion joining the head and base portions and having a shape that tapers outwardly from a narrow neck where it joins the head portion to the base portion.

Title: Method and apparatus for introducing a moving liquid into a larger mass of moving liquid
Inventor: TEMPLETON STEPHEN JAMES
IPC: B01D21/26
Filed: 2001-03-12
Abstract: In a vortex separator for use in at least partially removing suspended solids from a liquid containing suspended solids, the inlet port (8), whereby the liquid is introduced tangentially into a vortex chamber, has a substantially rectangular cross-section at a curved internal wall surface (2) of the chamber and the long axis of the rectangle is preferably aligned substantially parallel with the longitudinal axis of the curved internal wall surface (2).  The inlet port (8) preferably has a short side dimension which is not substantially greater than the thickness of the boundary layer of the liquid in the vortex chamber in use, so that the introduced liquid is substantially maintained in the boundary layer of the liquid at the internal wall surface.  This arrangement has been found to provide more efficient separation of the solids, which are discharged from the separator via discharge port (7) separately from the clean(er) water, which leaves the separator via the tangential outlet port (6) above the level of the inlet port (8).
