Abstract: La présente invention concerne un nanocomposite constitué d'une dispersion de particules nanocharges obtenues à partir d'oxydes métalliques en couches ou de sels d'oxyde métallique. On prépare avantageusement ce nanocomposite en faisant d'abord gonfler de l'argile non traitée dans de l'eau, et en retirant ensuite l'eau pour former de l'argile organophilique dispersable dans des solvants organiques non polaires. On peut alors traiter l'argile organophilique obtenue avec un aluminoxane d'alkyle puis avec un catalyseur, pour former un complexe activant la polymérisation oléfinique ou styrénique et la dispersion en plaquettes. Par ailleurs, on peut directement préparer le nanocomposite par polymérisation in situ de l'oléfine ou du styrène dans les particules nanocharges sans cisaillement, ni étape d'échange ionique, et sans avoir à ajouter des substituants polaires dans la polyoléfine ou le polystyrène.

Patent CA-2341956-A1 (CA)
Title: Improved bumper carrier and support
Inventor: SULLIVAN PATRICK D
IPC: B65G17/00
Filed: 2001-03-23
Abstract: A buffer/brake system is provided for carriers used in an automated assembly system. The rear ends of the carriers are each equipped with a flexible ring that is compressed when an upstream carrier strikes the flexible ring. Compression of the flexible ring causes it to expand and thereby engage the sidewalls of the track and the frictional engagement of the ring against the sidewalls of the track act as a brake for the struck carrier. The ring acts to absorb the shock resulting from the collision between the queued carrier and the oncoming carrier, thereby limiting the transfer of impact forces from pallet to pallet along the track. The ring is carried by a rotatable support which has a laterally extended ring abutment surface. The rotatable ring support is able to swivel, relative to the carrier to which it is attached, as the track makes turns in the assembly system. The abutment surface and rotatable support for the ring reduce the tendency for the ring to get caught and cause jams as the carrier rounds curves in the track of the assembly system.

Title: Light ring display for cooktop
Inventor: PLATT NILS
IPC: H05B3/74
Filed: 2001-05-24
Abstract: A method and apparatus for illuminating a heated area on a cooktop panel includes a light ring peripherally aligned about a burner under the cooktop panel, a gasket for resiliently retaining the tube beneath the cooktop panel and a support for resiliently engaging the gasket against the panel. Preferably, the light ring is a tube recessed within the gasket to avoid direct contact with the cooktop panel surface. The gasket may also restrict illumination to a channel portion of the gasket. Alternatively, the tube can be coated to avoid illumination in directions other than the area exposed to the panel. The gasket forms a convenient masking tool for delineating the surface area of the tube that is to be exposed while shielding other exterior surfaces of the tube. Both the illuminator and the method for illuminating the burner are simplified when the gasket includes a support flange beneath the tube retaining socket.

Patent CA-2351988-A1 (CA)
Inventor: CONKIE ALISTAIR D
IPC: G06F16/61
Filed: 2001-06-26
Abstract: A system and method for improving the response time of text-to-speech synthesis utilizes "triphone contexts" (i.e., triplets comprising a central phoneme and its immediate context) as the basic unit, instead of performing phoneme-by-phoneme synthesis. Prior to initiating the "real time" synthesis, a database is created of all possible triphones (there are approximately 10000 in the English language) and their associated preselection costs. At run time, therefore, only the most likely candidates are selected from the triphone database, significantly reducing the calculations that are required to be performed in real time.

Inventor: LINDQVIST MORGAN
IPC: G10L25/48
Filed: 1999-12-17
Abstract: To reduce the complexity of finding reconstruction points in connection with vector quantization, a set of reconstruction points close to a predicted reconstruction point is selected, whereupon a distortion measure is calculated for all the reconstruction points of the selected set, and that reconstruction point that gives the smallest distortion, is chosen as the optimal reconstruction point. Since only a small number of reconstruction points has to be searched, the complexity of the search is significantly reduced.
