Patent CA-2196606-A1 (CA)
Title: Tamper evident seal and tape
Inventor: SMITH CHRISTOPHER A
IPC: B65D33/34
Filed: 1995-08-02
Abstract: A tape or label for sealing a container that provides visual evidence if the seal is forced open or cooled below a breakdown temperature. The tape includes a plastic strip (20), a layer of ink (22) printed on a surface of the plastic strip, and a layer of pressure-sensitive adhesive (24). The tape can be incorporated into a bag (10) for sealing the bag closed. The tape includes an ink layer that is sandwiched between the plastic strip and the adhesive layer. The adhesive can be secured to portions of a bag to seal it closed. If the seal is forced open, the ink layer visibly delaminates from the plastic strip. The adhesive layer and the plastic strip are chosen to have different rates of shrinking when cooled, so that when the tape is cooled below its breakdown temperature, the ink layer delaminates. In an alternative embodiment of the tape, two layers of ink are printed onto the plastic strip. The first layer of ink is clear and is printed onto the untreated plastic strip in a pattern. The second layer of ink is opaque and is printed uniformly over the plastic strip and the clear ink after the plastic strip is treated.

Title: Artificial posterior tooth for humans
Inventor: KURA GUENTER
IPC: A61C13/097
Filed: 1995-09-08
Abstract: The present invention concerns artificial posterior teeth, namely large and small posterior teeth for the upper and lower human jaws. The occlusal surface of the tooth has at least one vestibular cusp (6) and at least one palatal cusp (5) between which a longitudinal groove (7) runs in the longitudinal direction of the tooth. The vestibular cusps (6) of the posterior teeth of the lower jaw engage in the grooves in the posterior teeth of the upper jaw, and the palatal cusps (5) of the posterior teeth of the upper jaw engage in the longitudinal grooves of the posterior teeth of the lower jaw. The longitudinal grooves (7) and the palatal/lingual cusps (5) and vestibular cusps (6), respectively, of the posterior teeth (34 to 37 and 24 to 27) are adapted to one another such that, in the region of the longitudinal grooves (7), at least one rest zone (11) is formed in which there is point-wise contact in the closed position of the posterior teeth (34 to 37 and 24 to 27, respectively).
Patent CA-2202045-A1 (CA)
Title: Methods and apparatus for establishing body pocket
Inventor: SEARE WILLIAM J JR
IPC: A61F2/82
Filed: 1995-10-17
Abstract: The methods and apparatus of the present invention permit a stable body pocket (3) to be formed utilizing multiple biocompatible sheets (10, 14) or using only a single biocompatible sheet (10) positioned to create either a potential space or actual space stable body pocket. The sheets (10, 14) have one surface (16, 12) which permits tissue ingrowth and thereby stably secures the sheet (10, 14) in the desired position. The other sheet surface (18, 20) is non-adhering such that adherence to a facing surface does not occur thereby creating a stable body pocket. In addition, a stable body pocket can be formed by using a biocompatible sheet or sheets (10, 14) having a surface (12, 16) that is selectively capable of permitting tissue ingrowth such that some portions of the surface grows into the surrounding tissue and other portions of the surface (18, 20) do not adhere to the surrounding tissue.      In this manner, the stable body pocket apparatus has flexible surface portions. Stable body pocket access channels can also be formed.      Such channels can provide stable means for communication between the exterior of the body and a natural or created internal body pocket.     A method for forming a stable body pocket utilizing fluid pressure introduced into the space where a body pocket is desired is also in accord with the present invention.

Title: Method for improving redispersibility of pigment inks for ink jet printing
Inventor: CHEN JING-DEN
IPC: C09D11/00
Filed: 1998-01-21
Abstract: An ink jet ink composition comprises a liquid vehicle, a pigment and an aqueous anionic black dye.  The addition of the dye in this ink jet composition results in a self-redispersible pigment ink for use in ink jet printers.  The dye is an aqueous anionic black dye selected from the group consisting of direct dyes, acid dyes, reactive dyes, and food dyes.  The self-redispersible ink is formulated from a carbon black pigment ink by adding a first amount of an aqueous anionic black dye to the carbon black pigment ink to create a modified ink.  This modified ink is evaluated for self-redispersibility.  Additional amounts of the aqueous anionic black dye are added to the modified ink, as needed, to create a self-redispersible modified ink for ink jet printers.
Patent CA-2228294-A1 (CA)
Title: Route finding in communications networks
Inventor: CHNG RAYMOND SOO KAIAW
IPC: H04L12/701
Filed: 1996-08-06
Abstract: A method of determining a restoration route (or an additional route) in a fully or partially meshed communications network of nodes, comprising sending, from a failure node a common help message on each span corresponding to a failed route, the common help message comprising a respective route ID field (and a respective associated route capacity field) for each failed route, and a route ID count field. A node which upon receipt of such a common help message initially determines itself to be the master end node for a plurality existing routes will generates and forward flood a common forward route-finder message for those failed routes. A slave node will respond to receipt of a forward route-finder signature to generate a respective return signature for the route for which it is slave, and send it back along the restoration route traversed by the received route-finder signature. Any tandem node of the restoration route which has less capacity than that requested by the route being restored will make connections for the available amount, forward the return signature with the capacity field overwritten with the available amount, and send a backtrack signature to the slave for that route to dismantle previously made connections in preceding tandem nodes and to inform the slave node of the amount of the capacity deficit. The slave node responds by switching to act as master and sending a reverse route-finder signature for the deficit amount, and the master responds to receipt of the return signature (whose capacity amount is less than the node knows is requested for the route) switches to act as slave for that route and awaits a reverse route-finder signature. The use of the common signature for a plurality of route IDs reduces the overall time to achieve restoration.
