Filed: 1997-10-09
Abstract: Cette invention concerne des dispositifs implantés servant au pontage de fluides, ainsi que des procédés permettant de réguler la pression de fluides dans des espaces ou des cavités de l'anatomie du corps. Ce dispositif (10) comprend, de manière générale, un tube (12) qui possède une barrière de diffusion (20), telle qu'un chambre de diffusion, formée à son extrémité proximale. Le fluide traversant le tube va s'amasser dans la chambre de diffusion (20) et se diffuser vers l'extérieur à travers celle-ci. La présence de la chambre de diffusion (20) permet en outre d'éviter que des microbes, des cellules ou toute autre matière n'entravent le tube (12) ou ne soient refoulés par celui-ci. Le tube peut en outre comprendre un orifice de libération de pression (30) à travers lequel le fluide peut s'écouler dudit tube dans la chambre de diffusion (20). Cet orifice (30) reste fermé jusqu'à ce que la pression du fluide dans le tube dépasse une pression maximale (pmax) prédéterminée. L'orifice de libération de pression (30) permet ainsi de limiter la quantité de fluide qui est drainée de l'espace ou de la cavité anatomique du corps, et d'éviter toute hypotonie dans cet espace ou cavité.

Title: Two-stage fuel tank vapor recovery vent valve and method of making same
Inventor: BERGSMA RUDOLPH
IPC: F16K24/00
Filed: 1999-10-28
Abstract: A two-stage venting on-board refueling vapor recovery (ORVR) valve for controlling fuel tank venting to a storage canister during tank filling. A float actuated poppet has a small second stage venting hole therethrough. The poppet is mounted for relative movement with respect to a second stage vent valve member disposed on the float. During tank filling, venting is through a first stage relatively large flow area passage until rising fuel level causes the poppet to close the first stage vent flow area. Venting during continued filling is through the second stage venting hole in the poppet. After first stage valve closure relative movement or lost motion occurs between the first and second stage valve members. The poppet has an integrally molded annular resiliently flexible seal thereon which has a first stage annular sealing surface formed on one side of the poppet for sealing the first stage flow area, and a second stage annular sealing surface about the poppet hole on the opposite side of the poppet for sealing the second stage vent flow area and closing the vent passage.

Title: Copy protection schemes for copy protected digital material
Inventor: LINNARTZ JOHAN P M G
IPC: H04N5/91
Filed: 1999-02-22
Abstract: Recent copy-protection schemes for digital video copy-protection rely on a pixel-watermark together with the presence of a "ticket" to implement the "copy-once" state of content. This ticket is designed to entitle the owner of a disk/tape to making one copy of digital content. We disclose a method to pass along this ticket with the video signal after content has been converted to the analog domain. This form of the ticket is called the analog ticket. The analog signal may be recorded on a legacy device that does not comply with the copy-protection scheme (e.g. ordinary VCRs). The analog ticket is designed such that it is automatically removed in these legacy devices. Next generation copies by compliant devices are made impossible. Three possible ways of embedding the ticket signal into the analog video signal are proposed.
Patent CA-2297600-A1 (CA)
Title: Blowout preventer protector and method of using same
Inventor: DALLAS L MURRAY
IPC: E21B33/068
Filed: 2000-01-28
Abstract: A blowout preventer (BOP) protector is adapted to support a tubing string in a well bore so that the tubing string is directly accessible during a well treatment to stimulate production. The BOP protector includes a mandrel having an annular sealing body bonded to its bottom end for sealing engagement with a bit guide that protects a top of a casing of a well to be stimulated. The mandrel is connected at its top end to a fracturing head, including a central passage and radial passages in fluid communication with the central passage.      The mandrel is locked in a fixed position by a lockdown mechanism that prevents upward movement induced by fluid pressures in the wellbore and downward movement induced by the weight of a tubing string supported at a top of the fracturing head by a tubing adapter. The advantages are that the BOP protector permits access to the tubing string during well treatment and enables an operator to move the tubing string up and down or run coil tubing into or out of the wellbore without removing the tool.      This reduces operation costs, saves time and enables many new procedures that were previously impossible or impractical.
