Patent CA-2251722-A1 (CA)
Inventor: BUENGER DANIEL EDWARD
IPC: A61F13/49
Filed: 1997-04-04
Abstract: La présente invention concerne des éléments d'absorption de fluides, lesquels éléments sont constitués de préférence de trois composants de base: d'abord des fibres chimiquement raidies, torsadées et prenant du gonflant par bouclage, ensuite des fibres de superficie élevée, et enfin un additif chimique servant de liant. Les éléments d'absorption des fluides de l'invention sont réalisés à partir de fibres de superficie élevée, un passage au fin conférant de la pression capillaire (ou succion) à l'élément d'absorption de fluides. Ces fibres de superficie élevée sont généralement courtes et hautement conformables. Elle confèrent au substrat une pression capillaire largement supérieure à la pression capillaire constatée avec une masse en vrac constituée uniquement de fibres chimiquement raidies, torsadées et prenant du gonflant par bouclage (non passées au fin). Celles des fibres que l'on préfère actuellement comme fibres à superficie élevée sont les fibres cellulosiques d'eucalyptus. L'eucalyptus, qui confère des caractéristiques intéressantes de pression capillaire lorsqu'on l'associe à des fibres chimiquement raidies, torsadées et bouclées, risque peu de traverser le voile de formage.

Filed: 1997-11-26
Abstract: A power recoilable rule has an improved bumper (60) for cushioning the recoil impact of the blade hook (20) when the blade (16) is refracted into the casing (12). The casing (12) has an opening (38) at a juncture between the bottom wall (32) and front wall (34), and a bumper (60) is mounted in the casing (12) within the opening for linear sliding movement relative to the casing in a path along the bottom wall (32).

Title: Packet data band control method in packet exchange network and packet exchange network system
Inventor: TAMURA MOTOSHI
IPC: H04L12/801
Filed: 1998-10-30
Abstract: Efficient use of an ATM transmission path becomes possible by multiplexing, into a bandwidth in the bandwidth-assured individual VP, a plurality of users whose traffic volumes are beyond a predetermined value. Installing a bandwidth-unassured common VP for low traffic users makes it possible to switch from the common VP to the individual VP or vice versa under the following conditions.   (1) When the user traffic volume, monitored at fixed intervals during the communications through a individual VP, drops below a predetermined threshold value, the individual VP is switched to a common VP.   (2) When the user traffic volume, monitored at fixed intervals during the communications through a common VP, exceeds a predetermined threshold value, the common VP is switched to an individual VP.   (3) In addition to condition (2), when bandwidth shortage takes place in common VPs, the common VPs of heavy traffic users are switched to individual VPs.

Title: Teeth-cleaning device with handle
Inventor: RUEB FRITZ ALFONS
IPC: A46B9/04
Filed: 1998-01-14
Abstract: The invention relates to a teeth-cleaning device (1) with a handle (2) which on one end, preferably on two opposite ends, has an interdental treatment element, for example in the form of a fine brush (3) or hard brush (4) and possibly even in the shape of a tooth pick. Said treatment element is positioned perpendicular to, and projects from, the longitudinal axis of the handle (2), and is removably and replaceably attached by means of a locking element (5) which can be detachably fixed in a locking position. To this end, the treatment element or a holding device forming part thereof, such as a retaining wire (4a), is inserted in the operating position into a hole (6) extending perpendicular to the longitudinal axis of the handle (2). When the locking element (5) clears this hole (6), the treatment element can be removed and a different one inserted. In the locking position, in contrast, the locking element (5) covers the hole (6) and thus prevents the removal of the treatment element inserted into said hole.

Abstract: Procédé et dispositif servant à accoupler des éléments tubulaires (12, 14, 16, 18, 20 et 22) d'un cadre (10) sans soudure ni collage. On utilise des éléments d'accouplement (24, 26 et 28) permettant de réaliser des accouplements mécaniques en faisant subir une déformation relative à un des éléments d'accouplement, ainsi qu'à son élément tubulaire respectif. Cet élément d'accouplement (24, 26 et 28) est, de préférence, conçu pour être introduit à l'intérieur d'une extrémité creuse d'un élément tubulaire et comporte des évidements (46) dirigés radialement vers l'intérieur.

On peut mettre ces éléments d'accouplement et ce procédé en application dans des cadres d'unités mobiles, telles que des bicyclettes (200), des fauteuils roulants (100) et des trottes-bébé. On peut également mettre en application la technique de façonnage utilisée afin d'accoupler les éléments tubulaires de cadre pour créer des caractéristiques d'adaptabilité au mouvement dans le cadre en déformant au moins un des éléments tubulaires, de manière à modifier sa constante élastique. Ces caractéristiques d'adaptabilité au mouvement sont, de préférence, des déformations à l'intérieur ou à l'extérieur de la circonférence du cadre.

Title: Method and apparatus for striping packets over parallel communication l inks
Inventor: PARTRIDGE CRAIG
IPC: H04L12/56
Filed: 1999-10-20
Abstract: A system for performing packet based data communications over a parallel set of sublinks is provided. A transmitter unit separates the sublinks into an available set of sublinks and a busy set of sublinks. This transmitter avoids processing delays by utilizing sublinks in the available sublink set and not waiting for sublinks in the busy sublink set to be released. To receive the packets, a receiver unit utilizes a sequence number associated with each packet. Accordingly, the receiver extracts the one or more packets of data received in parallel over the set of sublinks in sequential order. A packet window buffer is used to store packets in sequence if they are initially received out of order. The receiver utilizes a sliding window to provide packets in continuous sequential order and transmits the packets serially over a single communication link.

Title: A method for fabrication of multi-step structures using embedded etch stop layers
Inventor: LIM MARTIN G
IPC: G03F7/26
Filed: 1999-11-02
Abstract: A method of fabrication is provided for multi-step microlithographic structures including Fresnel lenses whereby the process includes the formation of intermediate etch stop layers that are embedded with the structure material.  This is accomplished in one aspect of the invention by depositing Fresnel lens material using known techniques and selectively altering the chemistry of the material being deposited to form the intermediate etch stop layers at suitable positions without interrupting the deposition process. In another aspect, etch stop layers are patterned on layers of the lens material and embedded between such layers. The structure, or lens, is then formed using masking, patterning and etching techniques.
