Patent CA-2487148-A1 (CA)
Inventor: ARTIGLIA MASSIMO
IPC: H04B10/291
Filed: 2002-05-31
Abstract: A pumping module comprising a cascaded Raman laser for Raman amplified optical transmission systems is disclosed. Non-linear parametric phenomena, such as Raman-assisted three-wave mixing, in Raman amplified signals from a cascaded Raman pump are strongly reduced by substantially suppressing from the output spectrum of the Raman pump the emission peaks at wavelengths shorter than that of the desired pumping wave on a specific wavelength .lambda.n, and within a given spacing from .lambda.n. The pumping non-zero dispersion fibres with zero dispersion comprised between the wavelength range of the transmission signal and the wavelength range of the pump signal.

Title: Strip diffuser pct i
Inventor: REILLY JAMES
IPC: B01F3/04
Filed: 2003-08-13
Abstract: Membrane strip diffusers are disclosed, useful for example in aerating wastewater in activated sludge plants. These diffusers have membranes, diffuser bodies and gas conduits elongated in the same general direction. Su ch conduits may be attached to or formed integrally with the diffuser bodies.

Title: Methods and devices for repairing tissue
Inventor: FROMM STUART
IPC: A61B17/064
Filed: 2005-02-24
Abstract: A suture anchor system for repairing torn or damaged tissue is provided and generally includes a first suture anchor having at least one length of suture attached thereto, and a second suture anchor having at least one length of suture attached thereto. Each length of suture is coupled to one another such that a distance between the first and second suture anchors with respect to each other can be selectively adjustable. The suture anchor system also preferably includes at least one slip knot that allows the first and second suture anchors to be maintained in a fixed position with respect to one another. In use, the suture anchors can be deployed through tissue to be repaired and into the anchoring tissue at a position spaced apart from one another by a selected distance. The suture length(s) can then be tensioned to re-approximate the torn or damaged tissue toward the anchoring tissue, thereby securely attached the torn tissue to the anchoring tissue.

Title: Method of enhancing hydraulic fracturing using ultra lightweight proppants
Inventor: BRANNON HAROLD DEAN
IPC: E21B43/267
Filed: 2005-09-20
Abstract: A subterranean formation having natural fractures, which is to be subjected to hydraulic fracturing, is first pre-treated with an ultra lightweight (ULW) proppant having an average particle size between from about 12/20 to about 40/70. The small ULW proppant flows into the natural fractures and packs the fractures. The formation is then subjected to hydraulic fracturing. The pre-treatment serves to enhance the effective propped fracture length of the formation during the hydraulic fracturing by reducing the loss of fluid from the subsequently pumped fracturing fluid. The method is applicable to hydrocarbon bearing formations as well as non-hydrocarbon bearing formations and has particular applicability to coal beds.

Title: Bitless bridle with crossover reinstrap stabilizer
Inventor: BROOKS ZOE C
IPC: B68B1/04
Filed: 2005-09-29
Abstract: A bitless bridle with crossover reinstrap stabilizer in English and Western style for riding, driving and training horses and like animals that achieves improved turning and slowing/stopping by threading reinstraps through a crossover reinstrap stabilizer under the horse's jaw, lining the inside of the noseband with rubber gripping or similar textured material, and improved arrangement of component straps. In both styles, a single crownpiece strap over the poll attaches on each side of the face to reinstraps that pass across the animal's cheek, through a crossover rein strap stabilizer under its jaw, then through rings attached to a noseband, and finally to reins. Pulling on a single rein places pressure on the reinstrap on the cheek of the opposite side of the animal's head, causing it to turn in the direction pulled. Pulling on a both reins places pressure on the noseband and the poll, causing the animal to slow or stop.

Title: Disposable dental instrument
Inventor: BROWNING JERRY W
IPC: A61C1/14
Filed: 2004-03-12
Abstract: A disposable dental instrument of the compressed air drive type is disclosed for use in performing dental procedures on a workpiece. The disposable dental instrument is constructed from two mating shells (30, 32) and a core (34).  Each shell (30, 32) incorporates a mating surface and the shells (30, 32) are joined using various bonding methods to ensure a waterprof, high quality dental instrument. An elongated body (910) has conduits (14) penetrating a base (16) at one end of the body (10). The conduits (914) allow entry of a light beam (18), a pressurized water stream (20), and a compressed air stream (22). Pluralities of passageways (26) are in communication with the conduits (14) for conducting the light beam (18), the pressurized water stream (20), and the compresed air stream (22) through the body (10). A head (44) at the opposite end of the body (10) rotatably mounts a turbine shaft (72) on bearing surfaces (64) which inhibit vibration and noise. The turbine shaft (72) includes a turbine impeller (74) and a clamping hole (80) for removable attachment of a dental bur (56) about a rotational axis. The opening (48, 54) in the body (10) adjacent to the head (44) allows release of the light beam (18), the pressurized water stream (20), and the compressed air stream (22) in a direction toward the distal end of the bur (56) so that the bur (56), the light beam (18), the pressurized water stream (20), and the compressed air stream (22) may all converge on the workpiece.
