Title: Method for making composite board using phenol formaldehyde binder
Inventor: WALSH PETE
IPC: B27N3/08
Filed: 1999-06-23
Granted: 2005-08-23
Abstract: Wood composite boards are produced from a wood fiber treated with a slow curing, low alkilinity phenol formaldehyde (PF) resin. The resin treated wood fiber is consolidated and cured in a press using steam injection. The slow curing nature of the resin prevents pre-cure of the resin. The press using steam injection speeds curing so that boards can be produced in press cycles comparable to the curing of wood fiber treated with other resins in a press with no steam injection.

Title: Improved eccentric drive shaft for atherectomy device and method for manufacture
Inventor: SHTURMAN LEONID
IPC: A61L31/18
Filed: 1999-03-17
Granted: 2009-05-19
Abstract: This invention is a method of manufacturing a rotational atherectomy drive shaft (20) having an asymmetrical tissue removal section (28). One or more strands of wire are helically wound about an elongated mandrel having an enlarged diameter section (28) with a predetermined shape, thereby forming an elongated, flexible drive shaft (20) which has an enlarged diameter tissue removal section (28).  A protion of the drive shaft (20), including the enlarged diameter tissue removal section (28) is placed into a first clamp, and given a first heat treatment to give the wire turns (31) of the enlarged diameter tissue removal section an initial set, thereby preserving the initial shape of the enlarged diameter tissue removal section (28) of the drive shaft (20).  The drive shaft (20) is then removed from the first clamp, and the mandrel (50) is dissolved. The enlarged diameter section (28) of the drive shaft (20) is then deformed to an asymmetrical shape by placing a portion of the drive shaft (20), including the enlarged diameter tissue removal section (28) into a second clamp. The clamped portion of the drive shaft (20) is then heat treated for a second time to give wire turns (31) of the enlarged diameter tissue removal section (28) a new set, thereby preserving the asymmetrical shape of the enlarged diameter section (28). In its asymmetrical shape the enlarged diameter tissue removal section (28) has a longitudinally flat "side", i.e., all wire turns of the tissue removal section may be connected by an imaginary straight line which throughout its length is parallel to the rotational axis of the driveshaft.

Title: Selective adherence of stent-graft coverings, mandrel and method of making stent-graft device
Inventor: BANAS CHRISTOPHER
IPC: A61F2/07
Filed: 1999-09-30
Granted: 2008-04-08
Abstract: A method for selectively bonding layers of polymeric material, especially expanded polyte-trafluoroethylene (ePTFE), to create endoluminal vascular devices. In a preferred method the se-lective bonding is achieved by applying pressure to selected areas using a textured mandrel. This permits a stent device to be encapsulated between two layers of ePTFE with unbonded slip pock-ets to accommodate movement of the structural members of the stent. This allows stent compres-sion with minimal force and promotes a low pro-file of the compressed device. Unbonded regions of ePTFE allow enhanced cellular penetration for rapid healing and can also contain a bioactive sub-stance that will diffuse through the ePTFE to treat the vessel wall.

Abstract: Méthode de traitement des calculs de planification complexes à partir des données d'un entrepôt de données ou d'un référentiel de données de planification lorsque certaines données agrégées ou certaines données de prévision pourraient être modifiées sans manipulation directe des données sous-jacentes et lorsqu'il pourrait y avoir plusieurs relations entre les données. La méthode permet de traiter des relations complexes sur plusieurs axes ou dimensions. Quelques itérations sont normalement utilisées, incluant à la fois l'analyse par simulation (back-solving) et son procédé inverse (forward-solving). Le sous-ensemble de cellules qui doit être calculé de nouveau est déterminé avant l'exécution des étapes d'analyse par simulation et/ou de son procédé inverse à l'aide de tables mères et dérivées. Le balayage des tables pour trouver des dépendances possibles est beaucoup plus simple et rapide que la recherche des formules ou des fonctions réelles reliant les cellules. L'étape de création des tables mères et dérivées est exécutée avant le calcul réel, par l'analyse des relations (formules et fonctions) entre les cellules des tables mères et dérivées et par la réduction des dépendances entre ces cellules.

IPC: B29C48/06
Filed: 2000-02-03
Granted: 2007-01-30
Abstract: An apparatus for continuously forming thermoplastic adhesive cartridges. A  molten thermoplastic adhesive supply provides a supply of molten adhesive to a pump (12) downstream from the molten thermoplastic adhesive supply. The pump (12) then provides a molten thermoplastic adhesive melt stream which passes through a screen filter (20) downstream from the pump (12) to prevent the discharge of impurities in the molten thermoplastic adhesive melt stream from the pump (12). A temperature-controlled conduit downstream from the pump (12) then lowers the temperature of the molten plastic melt stream to closely above its softening point. A continuous molder (14) located downstream from the melt pump (12) receives the molten plastic melt stream from the melt pump (12) to form the thermoplastic adhesive cartridge continuously.

Abstract: A hydraulic fluid reservoir and hydraulic pump combination has at least one hydraulic fluid port and includes a container with a hollow body having a top and a conduit having a bottom within the container and a top above the bottom. The conduit has an opening adjacent to the bottom of the conduit. The opening is spaced apart below the top of the container. A closure member is releasably, sealingly connected to the top of the conduit. Hydraulic fluid can be added to the container via the conduit up to the level of the opening of the conduit. Addition of further hydraulic fluid fills the conduit to the top thereof and the conduit overflows if additional hydraulic fluid is added after the top of the conduit is reached by the fluid. Preferably the container has a main interior chamber and a smaller chamber which is adjacent to one of the side walls of the container.  The smaller chamber is has a bottom opening near the bottom of the smaller chamber which communicates with the main interior chamber. Hydraulic fluid enters the smaller chamber through the opening and reaches the level of hydraulic fluid in the main interior chamber. Bubbles in the hydraulic fluid within the main interior chamber are isolated from the smaller chamber and accordingly do not impair the reading of the hydraulic fluid level by a photo detector.

Granted: 2009-10-20
Abstract: L'invention se rapporte à un dispositif que l'on passe dans les cheveux d'une personne pour isoler les cheveux par groupes de un ou de quelques cheveux. Une fois que les cheveux sont isolés dans des zones distinctes, on les traite, généralement afin de les embellir, de diverses manières qui ne seraient pas envisageables si les cheveux n'étaient pas isolés. Ces processus d'embellissement consistent, non exclusivement, à attacher un ou quelques prolongements de cheveux à un ou quelques cheveux du cuir chevelu, à restructurer les diamètres transversaux des cheveux individuels du cuir chevelu, à automatiser un processus de coupe précise des cheveux visant à couper de petits groupes de cheveux sur des longueurs soigneusement contrôlées, à appliquer des colorants capillaires et notamment les colorants qui produisent les meilleurs résultats s'ils ne sont appliqués qu'à un ou à quelques cheveux à la fois, à appliquer des produits chimiques pour frisure durable sur les cheveux puis à les enrober d'un produit protecteur qui empêche la fuite desdits produits chimiques et joue le rôle de fixateur maintenant les cheveux en place pendant le traitement chimique de sorte qu'il n'est pas nécessaire d'utiliser d'autres fixateurs tels que des bigoudis. L'invention concerne également un mécanisme raidisseur de cheveux qui facilite l'entrée des cheveux dans le système de traitement et d'isolement. Ce mécanisme permet aux cheveux de se dresser de manière plus perpendiculaire au cuir chevelu au cours du traitement. L'invention se rapporte également à divers moyens permettant d'empêcher que les cheveux ne s'accumulent à l'entrée du système de traitement que l'on déplace sur le cuir chevelu. L'invention se rapporte également, dans le cadre de la réalisation relative à la fixation de prolongements de cheveux, à un système de prélèvement de cheveux attachés au cuir chevelu et de réutilisation de ces cheveux consistant à les réimplanter sur le cuir chevelu. Finalement, l'invention porte sur la fabrication de prolongements artificiels pour cheveux qui ont l'apparence et se comportent comme des cheveux naturels, ainsi qu'à leur agencement dans des cartouches qui peuvent être utilisées par le système de fixation décrit ci-dessus.
