Patent CA-2437352-A1 (CA)
Inventor: LAFONTAINE DANIEL M
IPC: A61M25/08
Filed: 2001-09-13
Abstract: La présente invention concerne une valve à hémostase qui assure une étanchéité aux fluides en permanence de façon à prévenir le reflux sanguin, tout en n'offrant qu'un faible résistance par frottement à l'insertion de dispositifs. Cette valve à hémostase peut, soit faire partie intégrante d'un dispositif tubulaire tel qu'une gaine, un cathéter ou analogue, soit être détachable du dispositif tubulaire tel qu'un raccord en Y ou analogue. Selon un mode de réalisation, la valve à hémostase subit une force tendant à l'amener en position fermée en réaction à une pression distale de façon à prévenir le reflux de sang. La valve à hémostase subit également une force tendant à l'amener en position ouverte en réaction à une force ou à une pression proximale de façon à réduire le frottement à l'insertion de dispositifs. Par exemple, la valve à hémostase peut comprendre une pluralité de clapets ou de volets. Selon un autre mode de réalisation, la valve à hémostase est actionnée longitudinalement entre une position ouverte devant réduire le frottement pendant l'insertion du dispositif, et une position fermée devant empêcher le reflux sanguin en l'absence de dispositifs introduits.

IPC: G07F17/32
Filed: 2003-09-15
Abstract: The present invention integrates the concepts of interactive player based promotions, games, and bonusing that utilize a touch screen display on a gaming system associated with a remote player tracking system. The promotions are configured at a remote configuration workstation by selecting system criteria defining the particular bonus promotion to thereby create a "bonus rule." Promotions have four primary criteria. The first is the "Trigger" which is the criterion that determines when the bonus screen is activated to display a promotion. The second is the "Interface" that determines what will be displayed on the bonus screen. The third is the "Award's in which the nature of the bonus payment, including the method of choosing the value to award and the required player interaction to receive the promotion, is determined. And finally, the "Currency" system determines the method of payment to the player for earning or receiving the promotion.

Title: Zinc diacrylate predispersed in high-cis polybutadiene
Inventor: JOHANSSON ANDERS H
IPC: C08L9/00
Filed: 2003-10-23
Abstract: The present invention provides a method and product that provides a dust-free homogeneous dispersion of zinc diacrylate in polybutadiene for use in golf balls. More specifically, the invention relates to a dispersion of zinc diacrylate in a special high-cis grade of polybutadiene commonly used by golf ball manufacturers. We have found that such a dispersion of ZDA can be made by using specific processing promoters, which not only allow the manufacture of the predispersion, but have a beneficial effect on the final properties of the golf ball. The processing promoters of the present invention enable more uniform dispersion of the ZDA into the polymer matrix, eliminate sticking to the mixer rotors, provide improved extrusion and pelletizing rates, as well as function as a separant to greatly minimize, if not totally eliminate, massing of the palletized product. This dust-free palletized product, which can optionally be supplied in slab form, is then sold to the golf ball manufacturer for direct addition to his mixer. The presence of the processing promoter also assists in the mixing of the product into the final golf ball compound as well as improve down-stream processing, such as extruding.

Title: Zippered closure for flexible containers
Inventor: LAFOND LUC MARCEL
IPC: B65D33/16
Filed: 2003-11-17
Abstract: A re-closeable zipper is used to seal an opening in a flexible container such as a bag. The zipper includes two opposing zipper elements. The first zipper element defines a rib. The second zipper element defines a groove. The two zipper elements are positioned on the outside surfaces of two opposing walls of the container, adjacent the opening. To close the opening of the container, the rib of the first zipper element is pushed against the two opposing walls so that the rib and two opposing walls are locked within the groove, to form a tight seal. The zipper may be one or two pieces that are separable from the container, or the zipper may be fastened to, or manufactured as part of, the container. The invention also includes a container with a re-closeable zipper and a method of providing a re-closeable zipper for a container.

Each time a payment instruction is created, the system applies certain pre-negotiated payment terms and conditions between the buyer and the seller to the payment instruction. Afte r the payment instruction is created, the system seeks approval from the buyer . Upon approval of the payment instruction by the buyer, the system schedules the payment for the specified date in the payment instruction. The system calculates one or more fees, for the transaction according to a pre-defined variable pricing matrix, which is determined based on a set of pre-negotiate d conditions agreed to by the issuer, the acquirer, the seller and the buyer.< /SDOAB>
