Inventor: DELAHOUSSE XAVIER FRANCK YANN
IPC: B63C11/00
Filed: 2002-04-12
Abstract: Un dispositif de mise à l'eau et de récupération d'un véhicule sous-marin 20 comprend un ensemble submersible comprenant un châssis inférieur 24, un châssis supérieur 25, les châssis inférieur 24 et supérieur 25 étant reliés par une liaison souple, de façon que la distance entre lesdits châssis supérieur 25 et inférieur 24 soit réglable. La liaison souple et les châssis inférieur 24 et supérieur 25 forment une cage de réception 23 pourvue d'une ouverture 28 dont la dimension verticale peut être réglée. L'écartement des châssis inférieur 24 et supérieur 25 permet d'agrandir la dimension verticale de ladite ouverture 28, de façon que le véhicule sous- marin 20 peut pénétrer ou sortir de la cage 23 sans que les mouvements de la cage 23 dus au pilonnement ne gênent l'entrée ou la sortie du véhicule sous-marin 20. Le rapprochement des.châssis inférieur 24 et supérieur 25 dans le sens vertical  permet, malgré les mouvements verticaux de l'ensemble de la cage 23 dus au pilonnement, de venir supporter le véhicule sous-marin 20 sur le châssis inférieur 24, et de  le maintenir par le châssis supérieur 25.

Title: Apparatus and method for knitting a fabric with a lay-in yarn on a circular knitting machine
Inventor: RENDA JAMES A
IPC: D04B15/06
Filed: 2002-04-22
Abstract: A circular knitting machine has sinkers arranged for radially reciprocating around an upper portion of a cylinder, and latch needles arranged around the upper portion's perimeter for reciprocating along the axis of the cylinder. Selected ones of the needles draw down a lay-in yarn while the sinkers between the selected needles remain in a pushed forward position, so that the lay-in yarn overrides the nibs of the sinkers. In a preferred embodiment, each forth needle, and only each fourth needle, is selected to draw down a lay-in yarn, and four sinkers are positioned between each adjacent pair of the selected needles so that the lay-in yarn overrides four nibs between each draw down. The selected and non-selected needles engage jersey yarns at other knitting stations. This circular knitting machine can be adapted from existing knitting machines.

Title: Sheet for writing board and reflection type screen
Inventor: TAKAMOTO HIDEO
IPC: B43L1/10
Filed: 2000-11-06
Abstract: There is provided a sheet for a writing board and a reflection type screen having excellent writability and erasability when used as a writing board and having excellent anti-glare property when used as a reflection type screen without generation of hot spots. This sheet for a writing board and a reflection type screen is provided with a resin layer on at least one surface of a substrate on which a user can write with a writing board pen and erase the writing, and unevenness having an arithmetical mean deviation (JIS-B-0601) of 1.0-4.0 µm and a mean spacing of profile irregularities (JIS-B-0601) between adjacent protruded portions of 30-300 µm is formed on the resin layer by embossing. The resin layer preferably contains an ionizing radiation curable resin such as an ultraviolet ray curable resin. Since the unevenness is formed on the resin layer by embossing, an ink is not soaked in the layer and hence this sheet has excellent erasability as a writing board.

Title: Snow groomer assembly
Inventor: ALGER RUSSELL G
IPC: E01H4/00
Filed: 2002-07-22
Abstract: A snow groomer includes a movable platform, a prime mover mounted to the platform and a grooming drum rotatably driven by the prime mover for rotation in a direction opposite the traveling direction of the snow groomer.  The grooming drum includes axially spaced apart and radially protruding ribs that extend circumferentially around the drum. The ribs include circumferentially spaced apart apertures and the apertures of each rib are aligned with the apertures of the other ribs. Elongated cutting teeth extend through the apertures of the ribs and have a cross-sectional area that is smaller than the apertures such that the cutting teeth are free to vibrate within the apertures as the drum rotates, thereby enhancing the pulverization of chunks of snow and ice.

Title: Method for producing components using a flowable active medium and a forming tool
Inventor: GRUSZKA TINO
IPC: B21D26/02
Filed: 2001-04-04
Abstract: The invention relates to a method for producing components from a blank (P1 -P4) consisting of a deep-drawable material, especially steel, using a flowable active medium. During this method, the blank (P1 - P4) is clamped in a forming device (U1,U2) and exposed to the active medium. The blank (P1 - P4) is then preformed by increasing the pressure (P) exerted by the active medium in an area of the blank (P1 - P4) which is limited to a partial section (V1,V2) of the blank surface and which partially covers the surface section (B1,B2) of the blank (P1 - P4) from which the final form of the component is produced.  The preformed blank (P1 - P4) is then finished using a forming tool (F1,F2).

Title: Slurries of abrasive inorganic oxide particles and method for polishing copper containing surfaces
Inventor: PRYOR JAMES NEIL
IPC: C09D163/00
Filed: 2001-04-11
Abstract: Oxidizing agents are added to slurries of inorganic oxides which have been heated, e.g., autoclaved, to produce abrasive slurries which impart relative ly equal polishing rates for conductive metal and insulating layers used to mak e semiconductor chips. A relatively flexible abrasive slurry in terms of its abrasivity is also provided by this slurry, thereby permitting the modification of a copper polishing slurry's abrasivity when a new insulating  material is used to make a chip. When using this method, an increase in particle abrasivity of this slurry can be correlated with a decrease in particle surface area as determined by N2 adsorption (BET method) and abrasivity can be increased (or decreased) by heating the slurry to produce particles with a surface area determined to have the abrasivity desired. The  method is particularly suitable for preparing silica-based abrasive slurries  and the slurries prepared are particularly useful for polishing chips made with copper conductive circuits and silica-based insulating layers.

Patent CA-2409605-A1 (CA)
Inventor: KURTH CHRISTOPHER J
IPC: B01D71/82
Filed: 2001-05-23
Abstract: Semi-permeable membranes are described that allow for the efficent processing of many liquid based feed solutions, particularly those that contain acids.  The membranes of this invention are able to process such feeds with high permeate rates while maintaining excellent retention of dissolved metals, cations, and organic compounds, even in the presence of hot concentrated acids. The semi-permeable membranes of this invention are able to conduct such separations for a useful period of time due to their chemical stability towards acids and their ability to permeate acids.
Patent CA-2412017-A1 (CA)
Inventor: KRZYMINSKI KAROL J
IPC: A61K47/32
Filed: 2001-06-21
Abstract: A polymeric solution capable of gelling upon exposure to a critical minimum value of a plurality of environmental stimuli is disclosed. The polymeric solution may be an aqueous solution utilized in vivo and capable of having t he gelation reversed if at least one of the stimuli fall below, or outside the range of, the critical minimum value. The aqueous polymeric solution can be used either in industrial or pharmaceutical environments. In the medical environment, the aqueous polymeric solution is provided with either a chemic al or radioisotopic therapeutic agent for delivery to a specific body part. The  primary advantage of the process is that exposure to one environmental stimu li alone will not cause gelation, thereby enabling the therapeutic agent to be conducted through the body for relatively long distances without gelation occurring.

Abstract: La présente invention concerne un procédé de codage de la parole à basse vitesse sur la base du protocole réseau (IP). Ce procédé consiste à déterminer le paramètre attribut de la parole d'entrée pendant une période (TN) tout en déterminant la meilleure longueur de trame (T) du traitement de parole suivant ; à coder les données parole dans chaque T ; enfin à les sortir après leur mise en paquets par le protocole TCP ou UDP ou le protocole IP. L'utilisation du procédé de codage de compression de la parole à basse vitesse, pour une seule trame, une modification de longueur de trame, une auto-adaptation de bit de intré-trame, s'avère avantageuse pour augmenter l'aptitude au codage de compression et l'efficacité de la transmission. Puisque la partition de datagrammes IP utilise la partition de la trame codant la parole de meilleure longueur de trame sous la forme d'une unité, la qualité de codage et de décodage de la parole source est considérablement améliorée. Un test sonore informel indique si la valeur MOS peut être augmentée 0,1 - 0,2.
