Patent CA-2339110-A1 (CA)
Title: Static devices and methods to shrink tissues for incontinence
Inventor: ROY LOREN L
IPC: A61B18/08
Filed: 1999-07-29
Abstract: The invention provides improved devices, methods, and systems for repeatably and reliably contracting fascia and other support tissues, particularly for the treatment of urinary incontinence. Rather than relying on a surgeon's ability to observe, direct, and control the selective shrinking of pelvic support tissues, a relatively large surface of a tissue contraction system is placed statically against the target tissue. Sufficient controlled energy is transmitted from the surface into the engaged tissue to contract the tissue and inhibit in continence (or otherwise provide the desired therapeutic results).

Title: Abrasive diamond particles and method for producing the same
Inventor: ISHIZUKA HIROSHI
IPC: B24B37/00
Filed: 1999-08-30
Abstract: The invention has the principal object of providing a loose mass of minute abrasive diamond particles and an effective method for producing the same. The diamond particles meet at the same time these requirements for a slurry abrasive to be used in machining processes: (1) efficient removal of the work material per time, (2) minimized finished surface roughness, and (3) least of the diamond particles left as sticking on the surface of rather soft work material.   The diamond particles of the invention have a nominal size of 5 µm or less by D50 measurement and comprise an explicit thermal effect on the crystal structure due to a heat treatment at a temperature at least of 1000°C.  Further they are deposited on the surfaces with non-diamond carbon which amounts totally to 0.5%, at least, by weight relative to the whole diamond particles.  The method of the invention is in particular adapted for producing the diamond abrasive particles of modified properties. The method comprises: providing diamond particles of a D50 average particle size of 50 nm or greater and subjecting said diamond particles to a heat treatment at a temperature at least of 1000° C either in a non-oxidizing atmosphere or in a vacuum, and converting in part said diamond to non-diamond carbon.
Patent CA-2345190-A1 (CA)
Title: Self-cleaning filter with bypass
Inventor: MILLER ERIC J
IPC: B01D35/02
Filed: 2001-04-25
Abstract: A self-cleaning filter with a bypass port is provided for a washing machine that recirculates water back to the wash tub. The filter includes a housing with a filter element disposed therein. The filter element normally filters lint and other material from the water drained from the wash tub, with the water then being recirculated back to the wash tub.

Patent CA-2349271-A1 (CA)
Inventor: OLIN BIRGITTA
IPC: G06F9/50
Filed: 1999-09-08
Abstract: The present invention relates to load control in a processing system (40), and the invention employs a priority-level-based hierarchy of buffers (66) in which tasks are stored temporarily before being collected for further processing. The idea according to the invention is to define a number of reservation classes such that a predetermined set of the buffers of said hierarchy is assigned to each reservation class, and to determine a capacity distribution array in which values that identify the reservation classes are put in proportion to the capaciry given to the corresponding reservation class. By collecting the tasks from the buffers in accordance with the capacity distribution array, the capacity given to each reservation class is guaranteed during a so-called reservation interval.

Title: Heat added to underground cemented fill to obtain both early and long term strength increases
Inventor: SUN HENGHU
IPC: E21F15/00
Filed: 2001-11-26
Abstract: A method and apparatus for increasing the early and long term strength of underground cemented backfills includes adding heat to the backfill. A  cementitious binder is mixed with a sand component and water to form the mine backfill that may be a slurry or a paste. Heat is added to the backfill before the backfill is supplied to a mine cavity and this has been found to increase the early and long term strength of an underground cemented fill resulting from the backfill in the mine cavity. The backfill from the mixing step is mixed to have a pulp density of about 55% to 87%. Heat is added to the backfill so that the backfill has a temperature of about 18 to 60°C when it is supplied to the mine cavity. Heat is either added by heating the sand or water before the mixing step, or by heating the backfill after the mixing step. The mixing step uses a binder content of about 1.5 to 10% by weight.

Title: Wdm optical communication system using co-propagating raman amplification
Inventor: DU MEI
IPC: H04B10/2543
Filed: 2001-12-27
Abstract: The use of a co-propagating fiber Raman amplifier in an optical WDM transmission system has been found to be practical in the situation where the fiber amplifier is operated into depletion and the characteristics of the input signals are controlled to exhibit a reduced integrated relative intensity noise (RIN) over the fiber crosstalk bandwidth. In particular, the reduction in the integrated RIN can be achieved by increasing the number of input channels (by adding more messages or simply using dummy channels), encoding the data in a particular fashion to reduce the integrated RIN, or decorrelating the plurality of N input signals below a predetermined, relatively low frequency (for example, 2MHz).
