Title: Fractionateur ameliore de fluide
Inventor: HILL THEODORE B
IPC: B01D53/04
Filed: 1996-12-20
Granted: 2004-05-25
Abstract: Vanne rotative (21) située aux orifices de sortie d'une pluralité de colonnes (18), qui sélectionne sur une base cyclique des premières colonnes destinées à recevoir de l'air comprimé, à adsorber de l'azote et d'autres constituants dans l'air comprimé et à transmettre de l'oxygène et de l'argon à un utilisateur (par ex. un patient), des deuxièmes colonnes destinées à désorber les constituants adsorbés et des troisièmes colonnes destinées à égaliser les pressions, les premières colonnes changeant progressivement vers les deuxièmes colonnes et vice versa. Un compresseur (13) à caractéristiques réglables et régulé en boucle ouverte ou fermée introduit l'air comprimé par la vanne dans les premières colonnes, de manière à fournir un flux d'air réglable permettant de faire parvenir un flux prescrit d'oxygène à l'utilisateur. Une indication (88) peut être fournie lorsque les caractéristiques du compresseur régulées pour obtenir le débit d'oxygène prescrit se trouvent au-delà de limites particulières. La vanne peut avoir une vitesse variable dépendant des variations de flux du compresseur pour réguler la pression d'air dans les colonnes selon le débit d'air pénétrant dans les colonnes. Un orifice variable (27) ménagé dans une vanne placée dans chaque orifice de sortie de colonne se réduit avec la diminution du débit d'oxygène dans chaque colonne, ce qui régule encore la pression d'oxygène dans cette colonne. Un bouchon poreux fermant une chambre qui reçoit les constituants sous pression désorbés libère lesdits constituants lentement, sans bruit pulsatile, dans l'atmosphère. Ledit équipement produit donc le débit d'oxygène désiré avec une consommation minimale de puissance, un bruit réduit et une efficacité, une fiabilité et une durée de vie optimales. Ledit équipement peut être conçu pour transmettre d'autres constituants que l'oxygène.

Abstract: The present invention relates to an in vitro diagnostic method for the determination of specific dopamine-.beta.-hydroxylase activity for the evaluation of the sympathetic nervous system function of a patient from a serum sample; which comprises the steps of: a) filtering the serum sample to substantially remove drugs and endogenous inhibitors of dopamine-.beta.-hydroxylase; b) incubating the filtered sample of step a) with a substrate of dopamine-.beta.-hydroxylase for conversion in a detectable compound; c) determining the amount of detectable compound to evaluate dopamine-.beta.-hydroxylase activity and comparing with a normal sample; whereby an amount lower than a normal sample is indicative of a reduced sympathetic nervous system function and an amount higher than a normal sample is indicative of an increased sympathetic nervous system function. A reduction in the sympathetic nervous system function is indicative of neurodegenerative, neuroendocrine, psycho-affective and cardiovascular diseases, burn-out, and chronic fatigue, and the effects of stress such as panic syndrome. An increase in the sympathetic nervous system function is indicative of the effects of stress.

Abstract: A surgical staple line rein-forcement device for use with a variety of surgical staplers having a pivoted connection between sta-pler arms or jaws, such as endo-scopic stapler devices. The de-vice comprises a pair of tubes of bio-implantable material connected together at a hinge. The device can be quickly and easily applied to a surgical stapler by a surgical team to provide tissue reinforcement.      The hinged connection of the device provides both for secure attachment of the device to the surgical sta-pler, and for a barrier to protect the pivot connection from contamination by migrating tissue during operation.      Preferably, tear lines are provided on each of the tubes to assist in remov-ing excess material following attach-ment of staples. The device allows for fast and safe staple reinforcement and rapid stapler separation and re-moval following installation.

Title: Systeme de pompage actionne par gel polymere reactif
Inventor: SWATEK MIKE ALLEN
IPC: F04B43/09
Filed: 1998-08-12
Granted: 2002-01-08
Abstract: Un puits souterrain contient le fluide d'un puits de forage, un système de pompage étant placé à l'intérieur de ce puits de forage, sur un conduit. Ce système de pompage est alimenté en énergie électrique par un conducteur et comprend une chambre, une soupape de décharge, et une soupape d'admission, destinée à introduire le fluide du puits de forage à l'intérieur de ladite chambre. Cette chambre contient un réservoir rempli d'un gel polymère réactif, dont le volume se modifie considérablement en réponse à des changements environnementaux: le gel se dilate lorsqu'il est électriquement stimulé, ce qui éjecte le fluide de la chambre, mais se contracte en l'absence de stimulation, ce qui dirige ce fluide vers cette chambre. Lorsque l'on fait passer un courant électrique à travers ce gel, celui-ci se dilate et se contracte tour à tour, de manière à enclencher le pompage du fluide du puits de forage. Ce gel peut en outre être formulé de manière à réagir à un champ magnétique. Dans ce mode de réalisation, le gel renferme des particules métalliques dont la température augmente lorsqu'elles sont exposées audit champ magnétique, cette hausse de température provoquant une augmentation importante du volume de ce gel. Grâce à l'application d'un courant électrique à une bobine entourant le réservoir, le champ magnétique traverse le gel, ce qui fait augmenter le volume de ce dernier. Lorsque l'on fait passer ce courant électrique à travers cette bobine, le gel se dilate et se contracte, de manière à actionner le pompage dudit fluide du puits de forage.

Granted: 2008-09-30
Abstract: A first clad layer is formed on a smooth support substrate via a release layer. On the first clad layer, a core through which light propagates and alignment marks are simultaneously formed. Further, these layers are covered with a second clad to obtain an optical wiring layer. Then, the optical wiring layer is released from the support substrate and stuck to a substrate having an electric wiring. Subsequently, on the resulting substrate are formed a mirror for reflecting light propagating through the core, pads for installing optical parts or the like, and via holes for electrically connecting the electric wiring on the substrate to the pads. For this formation, the alignment marks are used as references.

Abstract: The present invention is directed to a releasable locking assembly for attaching a wear member to a support structure. It may be used with excavating equipment for attaching ground-engaging teeth to adaptors, lip shrouds to bucket lips, or other analogous uses. The wear member includes at least one pin-retainer-receiving opening in one side. The opening is tapered, being narrower at its outer surface and wider at its inner surface. The support structure includes at least one pin-receiving recess which generally aligns with the opening in the wear member when the wear member and the support structure are operatively coupled. The pin retainer is a frustoconically shaped cylinder which is threaded internally. It is inserted into the opening in the wear member. The wear member is slidably mounted onto the support structure. The pin is an elongate body which is externally threaded. It is screwed into the pin retainer by the application of torque force from a standard ratchet tool. The pin extends through the wear member and into the recess in the support structure to lock the wear member to the support structure. The pin may be released using a ratchet tool and removed from the pin retainer. The wear member may then be removed from the support structure.

Abstract: This application relates to antiviral tissue paper comprising pyrrolidone carboxylic acid as an antiviral agent. When added to tissue paper pyrrolidone carboxylic acid has the ability to kill certain strains of viruses which come into contact with the tissue. In addition to its antiviral efficacy, pyrrolidone carboxylic acid tends to be mild to the skin thus mitigating the potential for skin irritation. Furthermore, upon transfer to the skin, pyrrolidone carboxylic acid assists in retention of the natural moisture of the skin while continuing to kill deleterious viruses.
