Patent CA-2247891-A1 (CA)
Title: An expandable stent
Inventor: HANSEN PALLE M
IPC: A61F2/958
Filed: 1997-03-07
Abstract: An expandable endovascular stent comprises a flexible, tubular body (1) with a longitudinal axis, the wall of which is formed by interconnected, closed lattice cells (2) arranged with at least two cells adjacent to each other in the circumferential direction. Filament--shaped lattice material capable of transmitting compressive forces in the axial direction of the filament extends continuously from one lattice cell directly into the lattice cell following in the longitudinal direction.  The stent can be expanded from a radially compressed state into a radially expanded state having a larger diameter. In the expanded state of the stent, the pressure transmitting lattice material in several of the lattice cells (2) forms a heart-like or arrowhead-like shape with at least two interconnected diverging, angle .beta. cell sides (5) positioned opposite to and interconnected with at least two mutually converging, angle .alpha. longer cell sides (3). For stability during expansion and compression of a self-expanding stent, the sum of the first angle .alpha. and the second angle .beta. should be in the range of 345° to 360°, preferably at 360° to maintain a constant axial stent length.

Patent CA-2255460-A1 (CA)
Inventor: NEWMAN ELAINE B
IPC: C12Q1/18
Filed: 1998-12-11
Abstract: The present invention relates to a method to design   antibiotics,   which   comprises   testing   of compounds  which  inhibit  bacterial  cell  division  by blocking  the  s-adenosylmethionine-dependent  step  of formation of crosswall during cell division in bacteria and  other  microorganism.  The  S-adenosylmethionine-dependent step is catalyzed by the product of the yabC gene  (accession number COO2042, orf B)  of Escherichia coli. This gene has been cloned,  together with the first gene of the same operon, yabB  (accession number COO2041,  orfC).  Overproduction and underproduction of the yabC gene product is toxic to E. coli. Compounds which induce or repress the promoter of the yabBC, or increase production of the yabC gene product, as well as   inhibitors  of   the yabC   S-adenosylmethionine-dependent methylase will act as antibiotics.

Title: Rubber blend for tire tread compounds
Inventor: COLVIN HOWARD ALLEN
IPC: C08K5/5419
Filed: 1998-12-07
Abstract: This invention relates to a rubber blend that is easily processable and that can be beneficially used in tire tread rubber compositions.  This blend offers particular advantages in cases where silica is used as a filler in the blend.  This is because it is possible to attain a given level of modulus while employing a much lower level of silica coupling agent.  The blends of this invention can also be easily mixed while utilizing a mixing cycle of reduced duration.  These rubber blends also offer excellent tire performance characteristics such as good traction, treadwear and rolling resistance.  This invention more specifically discloses a rubber blend which is particularly suitable for utilization in making tire tread compounds which is comprised of:  (1) from about 1 phr to about 70 phr of a vinylpyridine containing rubbery polymer, wherein said vinylpyridine containing rubbery polymer contains from about 0.5 weight percent to about 15 weight percent vinylpyridine and wherein said vinylpyridine containing rubbery polymer has a Mooney ML 1+4 viscosity of less than about 25,  (2) from about 30 phr to about 99 phr of a styrene-butadiene rubber, wherein said styrene-butadiene rubber has a Mooney ML 1+4 viscosity which is within the range of about 40 to about 150,  (3) a silica filler and (4) a silica coupling agent.

Patent CA-2268073-A1 (CA)
Inventor: GOLUB HOWARD L
IPC: A61B5/352
Filed: 1997-10-14
Abstract: Arterial blood pressure of a subject (10) is determined by detecting the EKG  (12) and selecting a fiducial point thereof, preferably the R-wave. Apparatus, preferably a photoplethysmograph (14) is provided for monitoring blood volume versus time at a selected location on the subject's body such as a fingertip (16). A time difference between the occurrence of the selected fiducial point on the EKG and a selected change in blood in volume at the selected body location is determined. This time difference depends on the arrival time of the pulse at the distal location in addition to the shape of the blood volume versus time curve. Heart rate is determined from the EKG. The arterial pressure is computed from pulse arrival time, volumetric wave shape and instantaneous heart rate for each pulse. Methods are disclosed for determining diastolic pressure, systolic and mean arterial pressure. In another aspect, artifact detection and rejection are enabled. The invention provides for a continuous measure of blood pressure in a non-invasive, cuffless manner.

Title: Multi-channel audio enhancement system for use in recording and playback and methods for providing same
Inventor: KLAYMAN ARNOLD I
IPC: H04S5/02
Filed: 1997-10-31
Abstract: An audio enhancement system and method (10) for use receives a group of multi-channel audio signals (18) and provides a simulated surround sound environment through playback of only two output signals (26 and 28). The multi-channel audio signals (18) comprise a pair of front signals intended for playback from a forward sound stage and a pair of rear signals intended for playback from a rear sound stage. The front and rear signals are modified in pairs by a multi-channel audio immersion processor (24). The multi-channel audio immersion processor (24) separates an ambient component of each pair of signals from a direct component and processing at least some of the components with a head-related transfer function.      Processing of the individual audio signal components is determined by an intended playback position of the corresponding original audio signals. The individual audio signal components are then selectively combined with the original audio signals to form two enhanced output signals L OUT and R OUT for generating a surround sound experience upon playback.

Title: High-speed pouch forming, sealing and filling machine, method of operation, and multi-layer film therefore
Inventor: PITRE ANDRE
IPC: B65B51/30
Filed: 1999-05-14
Abstract: The multi-layer film structure having an inner sealing layer which comprises metallocene resin, a core which includes polypropylene copolymer and an outer layer and wherein the multi-layer film structure has a thickness within a range between about 50 and 70 microns (2.0 - 2.75 mil). By utilizing this thin film with specific properties the sealers may be operated at lower temperatures thereby resulting in an energy saving and they produce seals having improved seal strength of 30% to 50% as compared with known prior mono-layer polyethylene film. The seal initiation temperature is reduced by 10.degree.C to 15.degree.C and the film exhibits an improved machine direction tensile strength of 25% to 40% and an improvement of 30% to 50% in puncture resistance as compared with a 76 microns (3 mil) mono-layer polyethylene film. This results in a reduction in the sealing cycle time and an increase in the throughput of the machine. This results in a liquid pouch having a substantial improvement in drop test performance, puncture resistance and seal strength. The machine accomplishes better seals with less energy, requires less downtime for roll changes and maintenance and increase throughput.
