The matching abutment member has a bottom end which has a complementary interior bevel periphery surface (56), where the abutment member is installed over the top end of the implant fixture such that the complementary interior bevel periphery surface of the abutment member matches the bevel periphery surface of the top end of the implant fixture, thereby providing a perfect match therebetween.
Patent CA-2274090-A1 (CA)
Inventor: AMANO YOSHIFUMI
IPC: G09G3/20
Filed: 1998-10-06
Abstract: A method of maintaining/driving the discharge of an AC discharge display in which at least one of a pair of discharge electrodes is covered with a dielectric layer. A pulse Vy is a narrow width pulse whose pulse width is shorter than a period for which the priming effect of generated charged particles or quasi-stable atoms persists in a discharge space. A pulse Vx is a wide width pulse which is generated before the priming effect produced by the pulse Vy disappears and at about the time when the pulse Vy is generated and has a pulse width long enough for the discharge to stop due to wall charges generated on the dielectric layer. The pulses Vx and Vy are continuously applied between the pair of electrodes to generate a sustained discharge and the influence of the collision of ions against the discharge electrodes and the phosphor is reduced.

Abstract: A security door-locking system is described for locking an opening incorporating a hinged door, with a hinged side and an opening-outward side. Adjacent the opening-outward side of the door is a door-jamb portion incorporating a striker pin which is adapted to be latched by a latch on the door. The system includes a lock, and bar means for rigid extension between the striker pin and the lock. The bar means is substantially flat and has first and second ends. It further includes holding means adjacent the first end of the bar means for securely holding the first end of the bar means in place abutting the striker pin, and lock attachment means adjacent to the second end of the bar means for aiding attachment of the lock on the bar means. When the door is closed, the lock is selectively- attachable, outward of the opening, to the bar means adjacent to the second end of the bar means. The lock is also selectively- lockable, outward of the opening, to the bar means. The system is constructed and arranged in such manner that the door may be held securely shut when the lock is attached on the bar means, and the lock is in a locked condition.

Abstract: Cette souche de Lactobacillus salivarius, isolée à partir du tractus gastro-intestinal humain lavé et réséqué, inhibe une large gamme de micro-organismes du type Gram positif et Gram négatif et secrète un produit possédant une activité antimicrobienne dans un surnageant dépourvu de cellules. L'activité est produite seulement par les cellules croissantes et est détruite par la protéinase K et la pronase, les propriétés inhibitrices de la souche et les produits sécrétoires de celle-ci étant conservés en présence de concentrations physiologiques de bile et de suc gastrique humains. La souche de l'invention démontre un large spectre d'activité contre des bactéries, à savoir Listeria, Staphylococcus, notamment St. aureus résistant à la méthocilline, et Bacillus, mais n'inhibe pas nombre de Lactobacillus apparentés de façon proche à ceux-ci. L'invention concerne également un agent antimicrobien que l'on obtient à partir de cette souche et qui possède des propriétés du type bactériocine.
Patent CA-2282944-A1 (CA)
Inventor: MCKNIGHT DAVID WESLEY
IPC: H04L12/56
Filed: 1999-09-21
Abstract: An application and method for analyzing a virtual circuit in an asynchronous transfer mode ("ATM") network is disclosed. The ATM network may include multiple switches and connects two telecommunications networks through two interface devices, one for each telecommunications network. A virtual circuit is created in the ATM network between the two telecommunications networks, connecting to the first telecommunications network through a port of the first interface device and the second telecommunications network through a port of the second interface device. The method transfers a data value from the port of the first interface device to the port of the second interface device before or during a call. The data value identifies the two ports. In this way, the data value can later be examined to determine if it still identifies the two ports.      By so doing, the examining interface device can determine a status of the virtual circuit.

IPC: H04L12/56
Filed: 1998-09-30
Abstract: A monitoring system is provided with a two tier communication network.  Multiple first tier nodes comprising wireless or RF sensors are each equipped with transceivers operating at a first, low power level.  Multiple second tier nodes are spaced to communicate with selected sensors at the lower bandwidth level, and also communicate with each other at a higher power level and higher bandwidth, to route sensor communications to a central controller. The sensors comprise standard home and small business sensors such as motion detectors, glass breakage, pressure, temperature, humidity and carbon monoxide sensors to name a few, each equipped with a transceiver. The sensors are placed throughout a structure to be protected or monitored. Since such structures can be quite large, several second tier routers are provided such that at least one is within range of each sensor to receive its low power signals. A routing table is dynamically generated to direct communications between routers and the controller.
