Abstract: La présente invention concerne un procédé de formation d'un solide métallique composite à base d'alliages et/ou de composés intermétalliques. Ce solide est obtenu en comprimant à une pression modérée un mélange de poudres sous forme de particules, de pellicules ou de feuilles. Cette compression est réalisée à une température proche de la température ambiante, bien en dessous de la température de fusion des composants constitutifs, et sans additions de métaux à basse température de fusion tels que le mercure, l'indium ou le gallium intervenant comme agents de frittage. Cette consolidation à basse température du mélange de poudres est améliorée si la surface oxydée des particules de poudre est éliminée avant la consolidation, et/ou en enduisant les particules d'un métal remplaçant l'oxyde tel que l'argent ou l'or. L'opération d'enduction peut être réalisée par réactions de remplacement, de réduction autocatalytique ou de réduction électrolytique. La formation du composite est facilitée par l'addition d'un liquide tel que l'acide fluoroborique, l'acide sulfurique, l'acide fluorique, l'acide adipique, l'acide ascorbique ou l'acide nitrique. Une réalisation préférée du procédé de formation de solides composites métalliques concerne la formation de matière reconstitutive pour la dentisterie à températures ambiantes et à la pression normalement produite par les instruments dentaires à main.

Patent CA-2175021-A1 (CA)
Inventor: LEINSING KARL R
IPC: A61M39/04
Filed: 1996-04-25
Abstract: A valve mechanism for a needleless connector employs a deformable piston having a piston head of elliptical cross-section with a marquise-shaped bore formed along its longitudinal axis wherein the major axes of the respective generally elliptical shapes are oriented perpendicular to one another. The piston head is captured within the connector housing and is reciprocal between a section of reduced diameter adjacent the connection port and a section of enlarged diameter. Constraining the piston head into the section of reduced diameter causes the elliptical bore to be squeezed shut while positioning the piston head in the section of enlarged diameter causes the piston head to relax and assume its natural elliptical shape, while the boresimilarly regains its natural open shape to provide a fluid path therethrough. A compressible or extendible section affixed to the piston head serves to bias the piston into the section of reduced diameter. A tapered section of the piston contacts the housing to secure the top of the piston flush with the top of the housing for ease in cleaning.

Title: Infrared backbone communication network having a radio frequency backup channel
Inventor: MAHANY RONALD L
IPC: H04B1/38
Filed: 1996-03-29
Abstract: A communication network which uses an infrared backbone and having a radio frequency backup channel is disclosed. The infrared backbone is generally located on a ceiling in a hallway of a building (fig. 3) and comprises a plurality of hub access points (307). The hub access points (307) communicate data on the backbone in a relay fashion using modulated infrared light. If infrared communications fail, the hub access points (307) may, as a backup, communicate in the same fashion using low power radio frequency (RF) transmissions. In another embodiment, in an environment such as an airplane (figs. 11-12) having equipment sensitive to RF noise, a communication network is installed having communication pathways which adapt in response to such equipment as need be to minimize RF noise. For example, high-bandwith wired communication might be acceptable during some periods when the sensitive equipment is not in use. During other periods, the equipment may cause the communication pathways of the network to only utilize infrared transmissions or to enter an idle state. The access points use a sequential polling protocol and relay data throughout the network. Blocking and absorptive triangular shaped panels are used to absorb, deflect and contain infrared transmissions into cells.
Patent CA-2191703-A1 (CA)
Inventor: SMITH DAVID M
IPC: H04B3/04
Filed: 1995-05-11
Abstract: A high speed signal transport system (10) provides data transmission across a balanced channel (14). The balanced channel (14) carries differential signals from the output of a differential transmitter (12). An equalizer (18) compensates for distortion in the balanced channel in order to reduce timing jitter of the signal. The signal is applied to the input of a differential receiver (20) which exploits the precise quantization threshold inherent in differential data to accurately convert the signal to digital data. The differential receiver (20) also employs a known frequency reference along with digital transition detection to rephase the digital data to the local clock.  No duty-cycle limitation is placed on the signal carried by the balanced channel (14) and therefore the differential transmitter (12) and differential receiver (20) are not required to encode the signal. Because the signal-to-noise ratio seen by the differential receiver (20) is ample for accurate quantization, the equalizer (18) is optimized for jitter reduction in order to obviate the need for analog retiming circuits.

Filed: 1995-06-14
Abstract: Une pompe péristaltique possède un arbre monté à l'intérieur d'un corps et couplé à un rotor afin d'induire une nutation dans un disque en nutation. Une membrane est placée et fixée sur un côté du disque en nutation et au niveau de sa périphérie par rapport au corps. Une membrane est utilisée de l'autre côté du disque en nutation et assure un accouplement élastique dans une plaque d'entraînement avec le rotor. Un support sphérique supporte le disque en nutation et est sollicité par un ressort de sorte que le support et l'accouplement élastique forment un support élastique pour le disque en nutation. Un carter de pompe associé à la membrane forme une cavité avec la membrane. Des soupapes à boulet ou à clapet sont placées dans une admission et une évacuation pour réguler l'écoulement. La membrane de la pompe comporte une nervure de renforcement positionnée de manière sélective à l'intersection de la plaque-support de la membrane et du disque en nutation afin d'accroître la résistance par rapport aux pressions du liquide s'exerçant sur la membrane. Des cavités sont orientées et dimensionnées par rapport à une surface de la membrane afin d'éviter une déformation et une tension excessive à des points spécifiques de la membrane. Un élément d'insertion flexible encastré dans la membrane est utilisé pour raccorder le disque en nutation. Une protubérance de la membrane et une cavité se trouvant dans le disque en nutation permettent de renforcer également la membrane au niveau de l'élément d'insertion.

Title: Radiator Support
Inventor: HANAZAKI MASAHIKO
IPC: B60K11/04
Filed: 1996-12-20
Abstract: A radiator support includes a rigid inner tube member, a rigid outer tube member, and a rubber elastic member. The rigid inner tube member has a radial through concavity formed through the inner peripheral portion in the radial direction, or the rigid outer tube member has a radial through concavity formed through theouter peripheral portion in the radial direction. The rubber-elastic member has a convexity formed at least on one of the inner peripheral portion and the outer peripheral portion. The convexity extends inward or outward, and fits into the radial through concavity of the rigid inner tube member to inwardly project from the inner peripheral portion thereof, or into the radial through concavity of the rigid outer tube member to outwardly project from the outer peripheral portion thereof. Thus, therigid inner tube member can be assembled with an engagement pin of a radiator infavorable engagement, and the rigid outer tube member can be assembled with an engagement hole of a vehicle-side installation member in favorable engagement. As a result, the radiator support can inhibit abnormal noises from generating, and is less likely to come off from the radiator.
