Patent CA-2382187-A1 (CA)
Inventor: TIBBLES RAYMOND J
IPC: E21B43/04
Filed: 2000-08-17
Abstract: A well screen having an internal, blank al-ternate flowpath for delivering fracturing fluid/gravel slurry to different levels within a well annulus. The well screen is comprised of an outer pipe (18) which is positioned over a base pipe (17) thereby forming an annulus (19) therebetween.  The circumference of each pipe has a perforated sector and a blank sector, both of which extend along their respective lengths. When assembled, the respective perforated sectors are aligned to form a perforated, production sector and the respective blank sectors are aligned to form the blank, al-ternate flowpath. The base pipe is wrapped with wire (30) to prevent solids from flowing through the openings therein.  Slurry is pumped into the annulus where it flows circumfer-ently (33) from the blank, alternate flowpath to exit into the well annulus through the openings in the perforated sector of the annulus.

Title: Electronically controlled prosthetic knee
Inventor: PRATT GILL A
IPC: A61F2/80
Filed: 2001-01-22
Abstract: The present invention relates to a variable-torque magnetorheologically actuated prosthetic knee (110, 210) which utilizes a plurality of interspersed and alternating rotors (120, 220) and stators (130, 230) to shear magnetorheological fluid (130) in gaps formed therebetween. Advantageously, by operating in the "shear mode" there is substantially no or negligible fluid pressure buildup or change. Moreover, the multiple MR fluid gaps or flux interfaces desirably allow for the production of a large torque at low speed without the use of a transmission and also for a wide dynamic torque range to be achieved and add to the versatility of the invention. One embodiment of the invention allows the rotors (120, 220) and/or stators (130, 230) to close the gaps therebetween to create a frictional torque component, thereby forming a "hybrid" braking system which provides a total torque or damping which is a combination of viscous torque and frictional torque.

Abstract: A means and method for rigidly elevating a structure includes a base member securable in the ground and which has a portion extending above the ground. A pole section, having a bore inside a lower end, and an upper end, can be stacked upon the base means upwardly by slip fitting the pole section onto the base end and securing it in place. A flexible, easily transportable and durable system is thereby created for elevating structures.        An integrated pole for elevating light fixtures and all other necessary components such as electrical components, can be predesigned, shipped, and easily installed at a desired location.      Pole top member, including rigidly secured cross arms, can be inserted on the top of a pole. All wiring for both the pole top cross arms, and the pole itself can be preconfigured and require simple connection of plugs between wiring segments. Additional features can include ballast boxes which quickly attach to the pole by easy mounting brackets, and which also allow communication with the interior of the pole to allow easy electrical connection of its components. Still further, the wiring can be protected and reliably secured in the pole by structure and methods which deter abrasion or slippage.

Title: Promoters for molecular farming and/or early detection of transgenic plants
Inventor: SELVARAJ GOPALAN
IPC: C12N15/11
Filed: 2003-03-14
Abstract: Late embryogenesis abundant (Lea) proteins accumulate in maturing seeds after many of the storage compounds have been synthesized, and they are considered relevant to maturation. We report here the molecular organization and expression of BnLea3-1, a novel Group 3 Lea gene from Brassica napus. BnLea3-1 contains a coding region of 798 bp, sharing 84.4% homology at the amino acid level with Lea76 of B. napus. Two tandem 11-mer repeats are truncated from the coding region of BnLea3-l, compared to the 13 conserved 11-mer repeats of Lea76. Substitutions of consensus residues are found at various positions within the 11-mer repeats. A    by 5' flanking promoter fragment of BnLea3-1 fused to E. coli .beta.3-glucurondiase (GUS) coding region conferred seed-specific GUS expression in stable transgenics of B. napus, tobacco and in transiently-transformed pea. A -137 by minimal promoter preceding the first transcription start site, identified through progressive deletions from the upstream, was sufficient for basal GUS expression in the seeds arid in leaves treated with ABA. Deletion studies indicate the presence of enhancing elements located between -137 by to -742 by and suppressing elements located between -and -1561 bp. Bnlea3-1 expression in seeds precedes that of Lea76. Unlike other Group 3 Lea members including HVA1 and Dc3, BnLea3-1 is active in seeds and responsive weakly in vegetative tissues to ABA and methyl jasmonate (MeJA) hut not to stress treatments. Possible functions of BnLea3-1 and another member of the Group 3 Lea family BnLea3-2 in embryo development is discussed.
