Patent CA-2348570-A1 (CA)
Inventor: STEMKE LOTHAR
IPC: B29C45/02
Filed: 1999-10-27
Abstract: L'invention concerne le domaine de la transformation primaire de pièces en plastique par moulage par injection-compression, avec utilisation d'une cavité de dépôt communiquant avec le moule pour le stockage intermédiaire de la matière moulable fondue. L'objet de l'invention est d'améliorer le procédé de moulage par injection-compression mentionné de façon à exclure des défauts de structure et à réduire la dépense nécessaire à la finition mécanique des pièces. A cet effet, on introduit la matière moulable fondue, avant le moulage dans une cavité de moulage (kv), dans une cavité de dépôt (A) sous forme de cylindre, ayant un volume correspondant presque au volume de la cavité de moulage (kv) et communiquant avec la cavité de moulage, la cavité de dépôt (A) débouche sans transition dans la cavité de moulage (kv), et on amène la matière moulable de la cavité de dépôt dans la cavité de moulage au moyen d'un piston se déplaçant axialement dans la cavité de dépôt (A). Au début du processus d'injection, le piston se trouve à un premier point mort où le fond du piston est aligné avec le bord de la cavité de dépôt (A) et avec la paroi de la cavité de moulage de telle manière qu'une petite quantité de matière moulable fondue parvient directement dans la cavité de moulage. Le piston glisse alors dans le cylindre. Ce faisant, la cavité de dépôt (A) s'agrandissant de manière continue se remplit de matière moulable fondue presque sans pression de sorte que la matière moulable fondue est amenée de manière continue dans l'âme plastique jusqu'à ce que le piston atteigne sa deuxième position de point mort. On arrête l'amenée de matière moulable fondue à cet instant. On déplace ensuite le piston juste devant sa première position de point mort et on remplit ainsi complètement la cavité de moulage (kv) avec de la matière moulable. Pendant le temps d'arrêt, on amène le piston à la première position de point mort afin de compenser le retrait.

Title: Drainage system for artificial grass using spacing grid
Inventor: PREVOST JEAN
IPC: E01C3/00
Filed: 2001-07-12
Abstract: A drainage system is provided for a synthetic grass turf assembly having a flexible and water permeable sheet backing for installation on a supporting soil substrate to provide a game playing surface. The draining system of the present invention prevents water from accumulating on the turf surface, which could cause the top-dressing layer to "float" and be moved by inundation. The draining system of the present invention includes a spacing grid disposed between the backing of the turf and a porous aggregate layer over the supporting soil substrate.      The spacing grid is structured to permit water not only to be drained vertically through the spacing grid into the porous aggregate layer, but also to be drained horizontally through the spacing grid to the edges of the field when water is accumulated in the porous aggregate layer beneath the spacing grid and cannot be drained away promptly. The spacing grid is made from one or more types of geotextile or plastics material with an adequate flexibility to improve the impact absorption capabilities and resilience of the synthetic grass turf assembly.

Title: Magnetized pre-wound sideless bobbins
Inventor: FULLER EDWIN E
IPC: D05B57/28
Filed: 1999-12-16
Abstract: Magnetized bobbin cores (10-1) are preferably wound with sewing thread to obtain sideless, pre-wound bobbins that have beneficial draw-off tensions, draw-off tension uniformity and overspin characteristics.  The pre-wound sideless bobbins (10-1) may thus be satisfactorily used in lock stitch sewing applications due to improved uniformity of draw-off tension combined with reduced bobbin overspin. The magnetized pre-wound sideless bobbins (10;1) are also especially well suited for end-use sewing applications where automatic bobbin changing equipment is employed. Most preferably, the core is a cylinder formed of thermoplastic or thermoset material in which magnetized particles are dispersed.
Patent CA-2355908-A1 (CA)
Inventor: ABEND THOMAS P
IPC: C09J175/04
Filed: 1999-12-01
Abstract: The invention relates to one-pack aqueous dispersions or solutions of functional polymers, whereby said dispersions or solutions have a long shelf life, and to surface-deactivating solid polyisocyanates which cross-link under normal conditions. The aqueous dispersions contain solid polyisocyanates which have been surface-deactivated with polyamines. Said polyisocyanates have an average particle size less than or equal to 10 µm and functional isocyanate-reactive polymers. Characteristics of the polymers which are dispersed or dissolved in water are a minimal film-forming temperature (MFT) less than or equal to +5~ C, a glass-transition temperature Tg less than or equal to -5~ C  and a storage module G' less than or equal to 107 Pa when measured at 10 Hertz and at 10~ C. After application and evaporation of the water, a closed film is building up. Said film can dissolve the surface-deactivation of the solid isocyanates which are dissolved in the polymer phase and react spontaneously with the functional groups under normal conditions, i.e. with the hydroxyl and amino groups of the polymer. Polymer layers having a higher heat and solvent resistance are the result. Said layers can be used as contact adhesives, assembly adhesives or coatings.

Title: Laminated polyester resin container and method of molding such a container
Inventor: SUZUKI MASATO
IPC: B29C49/64
Filed: 2000-11-29
Abstract: A multilayer preform having at least a medium or intermediate gas barrier layer is prepared in advance by the injection molding of this preform in a predetermined shape that corresponds to the shape of a finished molded product. The body portion of this preform is heated to a blow moldable temperature. The heated preform is set in a primary blow mold (12), and is blow molded in the biaxial orientation to give a primary molded intermediate (5). The primary intermediate (5) is then heated to deform it forcibly by thermal shrinkage and thereby to give the secondary molded intermediate (6).  The shrunken secondary intermediate (6) is set in a secondary blow mold (13), and is subjected to the secondary blow molding in the biaxial orientation to obtain a finished molded product, which is fixed thermally to give heat history to the PET resin. As a result, the PET resin layers are given a high degree of crystallization, which serves to complement the function of the gas barrier layer or layers in such a way that the container has high and effective gas barrier properties.

Abstract: A method is disclosed for making vascular prostheses from ePTFE said prostheses having a diameter which is larger, and a wall thickness which is smaller than previously achievable using ram extrusion techniques. The metho d consists of extruding a PTFE tube, finish processing the tube into an ePTFE tube, laterally dilating it by expansion in incremental steps, calendering t he tube after each dilating step, while the tube is being maintained at an elevated temperature. Once the tube is dilated it can be sintered with anoth er tube to form a laminate. Alternatively, a wire stent may be joined with one or more tubes, thereby biasing the laminate to a cylindrical configuration.</SD OAB>

Inventor: COMAIR CLAUDE
IPC: G06T13/00
Filed: 2000-12-06
Abstract: A fast, texture morphing algorithm for real-time computer simulation and video games dynamically generates objects "on the fly" by simplifying and reducing the computational load required for a texture morphing/blending process.  Incremental interpolation techniques compute a morh parameter based on previous value and morph change rate. Precomputed initial and incremental morph parameter values for each texel component are applied during real-time morphing procedures using integer arithmetic. Approximation errors are reduced by incrementing/decrementing by an extra integer value when the number of morph iterations is a multiple of a frame counter. The frame counter avoids over-runs, and the morphing procedure is "snapped" the texel value to the precise texture target value to prevent under-runs and corresponding artifacts. Interlacing (applying interpolation to a subset of the texels each frame) significantly reduces computational load without introducing significant image artifacts. The morph texture buffer data structure is initially decomposed off-line to reduce the number of real-time calculations required to manipulate texel component data.
