Filed: 1996-01-05
Abstract: Cette invention porte sur un dispositif d'attache refermable comprenant un élément d'attache femelle (12) comportant, de préférence, une bande de base (53) et une couche de contact (54). La bande de base (53) comporte une bande (52) de film du type élastique structural (SELF), et est jointe à la couche de contact comprenant plusieurs filaments ou une bande en non tissé. La bande (52) SELF présente des propriétés élastiques dans le sens de l'allongement sans qu'il soit nécessaire d'utiliser des matériaux élastiques supplémentaires. Ladite bande SELF comporte également un réseau déformable constitué d'au moins deux régions distinctes faites du même matériau. La première région (64) est orientée de manière sensiblement parallèle à un axe d'allongement de sorte qu'elle subit une déformation au niveau moléculaire en réaction à une force d'allongement appliquée axialement, dans un sens sensiblement parallèle à l'axe d'allongement, avant qu'une partie importante de la seconde région (66) ne subisse une quelconque déformation, une déformation géométrique notable en réaction à une force d'allongement appliquée dans un sens sensiblement parallèle à l'axe susmentionné. Les secondes régions (66) comportent plusieurs éléments (74) en forme de nervures faisant saillie, agissant de concert avec les filaments ou la bande en non tissé pour constituer un élément femelle d'un meilleur rendement et mieux à même d'être agrippé par les crochets d'un élément d'attache mâle complémentaire.

Patent CA-2219797-A1 (CA)
Inventor: DIEGA-MARIADASSOU GERALD
IPC: C01B21/06
Filed: 1996-03-19
Abstract: L'invention concerne un procédé de préparation de carbures et de nitrures d'éléments de transition sous forme extrudée à partir de leurs oxydes et dont le volume et la répartition des pores est commandée. Les mésopores et les macropores sont générés par des molécules organiques polymères, telle que de la cellulose microcristalline, qui, après combustion, constituent une structure poreuse plus ouverte. Le procédé de moulage permet d'obtenir des composés intermédiaires susceptibles d'être soumis à une peptisation et à une extrusion ultérieure. La préparation de ces composés, dont les pores présentent un diamètre supérieur à 50 angströms, est réalisée dans une succession de réactions catalytiques étant donné que des structures poreuses plus ouvertes permettent d'effectuer le traitement catalytique de molécules plus importantes. De plus, ce procédé permet de limiter les problèmes posés par des traitements thermiques et de diffusion en masse et apparaissant avec des catalyseurs très actifs et/ou des réactions extrêmement exothermiques.
Patent CA-2220879-A1 (CA)
Title: Optical data storage system with multiple write-once phase-change recording layers
Inventor: TANG WADE WAI-CHUNG
IPC: G11B7/257
Filed: 1996-03-08
Abstract: An optical disk drive (10) uses an optical disk (12) with spatially separated multiple phase-change WORM recording layers (51, 66). The optical disk has a light transmissive substrate onto which the laser light is incident. The substrate supports at least two spatially separated multi-film recording stacks (90, 92), each stack including an active recording layer of phase-change WORM material. The disk is either an air-gap (78) structure wherein each recording stack is supported on a separate substrate (50, 56) and the substrates (50, 56) are separated by an air-gap (78), or a solid structure wherein a solid light transmissive spacer layer (22) separates the recording stacks (90, 92). Each of the recording stacks (90, 92) located between the substrate (50) on which the laser light is incident and the farthest recording stack includes an active phase-change recording layer (51) and an optical interference film (53) in contact with the recording layer (51). The recording layer (51) is made sufficiently thin to have good light transmissivity, but at this low thickness, without any other layers, is not sufficiently reflective to act as a recording layer with suitable servo and recording performance. The optical interference film (53) in contact with the recording layer (51) has a high index of refraction relative to the adjacent recording layer (51) and spacer (122) to increase the optical interference effect in the recording stack (90). The optical interference film (53) optimizes the contrast, reflectivity and transmissivitzy of the recording stack. The optical interference film (53) has low absoprtion so that laser light can pass through it to focus on a farther recording layer (66). This allows the farther recording layers (66) to be written using reasonable laser power.

Title: Controlling atm layer transfer characteristics based on physical layer dynamic rate adaptation
Inventor: GIROUX NATALIE
IPC: H04L12/56
Filed: 1997-11-28
Abstract: A system and method for managing data traffic through a path that includes a transmission link having a transport rate that is subject to change with time. The data traffic is shaped to ATM Forum's available bit rate (ABR) category of service. ABR traffic has an integrated resource management (RM) cell that returns congestion related information to the source over a feedback path. With this congestion information the source is able to tailor its traffic send rate in order to accommodate any reduced transport rate encountered by the traffic due to dynamically changing rate over the transmission link.
Patent CA-2223242-A1 (CA)
Title: Apparatus and method for hydraulic finishing of filament fabrics
Inventor: TY FREDERICK
IPC: D04H1/46
Filed: 1996-06-07
Abstract: An hydraulic treatment apparatus (10) and method is provided for finishing and upgrading the quality of filament cloth materials. The fabric (12) is supported on a member (52, 54) and impacted with a uniform, high density jet, fluid curtain (34, 70) under controlled process energies. Low pressure/low energy treatments spread filaments in the fabric to reduce air porosity and provide improved uniformity in material finish. High pressure and energy treatments increase fabric bulk and porosity. Fluid treated fabrics of the invention demonstrate substantial improvement in at least two of uniformity, cover, opacity, increased or decreased bulk, increased or decreased air permeability, abrasion resistance, tensile strength, edge fray, and seam slippage.

Title: An adhesive, sealing and coating compound
Inventor: LOTH HELMUTH
IPC: C08L25/08
Filed: 1996-06-19
Abstract: A gluing, sealing and coating compound based on a styrene copolymer is characterised in that the styrene copolymer mainly contains styrene and in that it contains an aromatic compound-free polyalkylene oxide and/or its fatty derivative. These non-toxic plasticisers are easily tolerated and increase stickiness, elasticity and stretchability. These compounds are therefore suitable as binders for producing glues, coatings and sealing compounds.
