Patent CA-2422808-A1 (CA)
Inventor: CARBONNEAU MICHAEL
IPC: A44B18/00
Filed: 2001-09-19
Abstract: A releasable strap (10) of hook and loop material is formed by continuously introducing molten resin (44) to a gap (42) defined adjacent a rotating mold  roll (22) having an array of fastener element cavities (20), to form a band of hooks (12) extending from one side of a strip-form base (15). The resin also  extends over an edge region (46) of the mold roll devoid of fastener element  cavities, extending along one side of the molding region (45) of the mold roll, to form an edge portion (15') of the strip-form base devoid of fastene r elements. A loop material (50) is bonded to an opposite side of the strip-fo rm base (15), such as by introducing the loop material to the resin in the gap (42), and the resulting product is cut across both the band of fastener elements and the edge portion (15') of the strip-form base, to form straps (10) having end portions devoid of fastener elements (12).

Title: Method and apparatus for reducing impurities in cellulose fibers for manufacture of fiber reinforced cement composite materials
Inventor: MERKLEY DONALD J
IPC: D21C9/10
Filed: 2001-09-25
Abstract: A method of manufacturing high purity fiber cement grades of cellulose fiber s is described. Additional washing steps, coupled with an elevated temperature , are used in the process to extensively wash the pulps and remove substantial ly all COD components remaining in the pulps. The pulps are counter-currently washed by diffusion and dewatering at elevated temperatures following the brown stock washer systems. During the additional washing steps, the pulps a re soaked in counter-current heated water for a pre-determined time and some chemicals may be introduced to chemically break down the COD components in t he pulps and to make them more soluble in the aqueous solution. The additional washing steps can be performed using existing equipment at conventional pulp  mills. A formulation and a process of making fiber reinforced cement composi te materials are also described using the low COD and high purity cellulose fibers. The pulps with lower COD contents have superior performance in manufacture of fiber reinforced cement composite materials. A smaller amount  of the low COD and high purity fibers is needed to achieve the same reinforcement efficiency, compared to regular cellulose fibers.

Filed: 2001-12-14
Abstract: A method of creating an implantation material from biological and tissue engineered biosynthetic and biological tissue of autogenic, allogenic and xenogenic origin suitable for implantation into humans or animals as surgica l and vascular prostheses. The resultant material inhibits in vivo calcificati on and provides a non-porous biomatrix which is impervious to angiogenesis and tissue ingrowth and suitable for the adhesion and retention of transplanted living cells such as endothelial cells, without the need for additional extracellular matrix protein coating. The method, which incorporates a gradu al increase in glutaraldehyde concentration from 0% to no more than 5% weight/volume in a pH which is gradually changed from acid to alkaline at ro om temperature, maintains the micro-architecture and the cellular lining of the  material. Additionally flexibility, compliance and haemo-compatibility along  with strength and durability can be varied according to the end use. The glutaraldehyde penetrates the material gradually and completely, cross linki ng the collagenous components of the tissue.

Title: Coaxial catheter system for performing a single step cryoablation
Inventor: LENTZ DAVID J
IPC: A61B18/02
Filed: 2003-08-13
Abstract: A system for cryoablating target tissue at a treatment site includes an annular shaped balloon attached to the distal end of a first catheter. A cryo-element is attached to the distal end of a second catheter and the second catheter is disposed in the lumen of the first catheter. The cryo-element is positioned at the treatment site using the second catheter. Next, the first catheter is used to advance the balloon over the second catheter to the treatment site where the annular shaped balloon is interposed between the cryo-element and the target tissue. Saline solution is pumped into the balloon to expand the balloon into contact with the cryo-element and the surrounding target tissue. Next, a refrigerant is expanded to cool the cryo-element, which in turn, freezes the saline solution. The resulting "ice ball" extracts heat from surrounding tissue resulting in the cryoablation of a substantially circumferential portion of tissue.

IPC: G02B6/10

Abstract: One-dimensional nanostructures having uniform diameters of less than approximately 200 nm. These inventive nanostructures, which we refer to as "nanowires", include single-crystalline homostructures as well as heterostructures of at least two single-crystalline materials having different chemical compositions. Because single-crystalline materials are used to form the heterostructure, the resultant heterostructure will be single-crystalline as well. The nanowire heterostructures are generally based on a semiconducting wire wherein the doping and composition are controlled in either the longitudinal or radial directions, or in both directions, to yield a wire that comprises different materials. Examples of resulting nanowire heterostructures include a longitudinal heterostructure nanowire (LOHN) and a coaxial heterostructure nanowire (COHN).

Abstract: A method for identifying active site inhibitors of scission enzyme that cleaves the backbones or side groups of peptides, and for using the resultant inactivators to inhibit the target scission enzyme. Kinetic assays are employed to identify peptide substrates that tightly bind to the active site of the target protease but that are not easily cleaved. These noncleavable but tightly binding substrates are optionally structurally modified to yield inhibitory compounds with optimized properties. Additionally these substrates exhibit apparent specificity for a transition state or ground state configuration of the protease.

Abstract: An injection molding system includes a manifold and a valve gated hot runner nozzle. The gating mechanism includes an actuated valve pin, where the mold gate orifice is open when the valve pin is in a first position to allow melt to flow there through. The mold gate orifice is closed when the valve pin is in a second position to prevent melt from flowing there though. A flow control pin is disposed within the melt stream, either coaxially with the valve pin within the melt channel of the nozzle or within the manifold melt channel.     The flow control pin has a head with a complementary geometry with that of the melt channel at a flow control surface. The flow control pin is raised and lowered by an actuation mechanism to constrict or release the flow of the melt stream independent from the movement of the valve pin.
