Title: Method of controlling structure stability of collagen fibers produced from solutions or dispersions treated with sodium hydroxide for infectious agent deactivation
Inventor: MARTIN GEORGE R
IPC: C08H1/06
Filed: 1995-04-12
Granted: 1999-05-18
Abstract: In accordance with the present invention, it has been discovered that the stability of collagen fibers is altered upon treatment of a solution or dispersion of the collagen fibers with a chemical reagent for the inactivation of infectious agents. This fiber destabilization makes it difficult to formulate the collagen fibers to final product when the formulation contains an ingredient which alters the destabilized collagen fibers. Collagen fiber stability in a collagen dispersion can be controlled using either a physical fiber-stabilizing agent or a chemical fiber-stabilizing agent. The physical fiber-stabilizing agent is used to protect the stability of the assembled fibers, without providing for covalent bonding between fibrils which make up the fibers. The chemical fiber-stabilizing agent is used to provide covalent bonding between fibrils, whereby the fibers are stabilized. A stabilized dispersion of collagen fibers is achieved by the presence of a physical fiber-stabilization means comprising a polymeric material of the kind which is capable, at sufficient concentration, of causing collagen fibers to precipitate from solution. Preferred polymeric materials are water soluble or water miscible. Preferably the water soluble or water miscible polymeric material is biocompatible, such as a polyethylene glycol or derivatives thereof. A stabilized dispersion of collagen fibers is also prepared by using a chemical fiber-stabilizing agent which crosslinks fibrils within the fiber, stabilizing the fiber. A preferred method of stabilizing the collagen fiber produced from a solution ora dispersion of collagen treated with an agent for the inactivation of infectious agents is to stabilize the collagen fiber subsequent to the treatment, by using one of the physical or chemical fiber-stabilizing means.

Abstract: Un gain de codage est amélioré en utilisant un codeur en treillis de dimension N intégrant un codeur convolutionnel de dimension N' où N' est inférieur à N. Le gain de codage supplémentaire est atteint avec un gain de mise en forme. Ce modulateur unique code un signal numérique en générant une séquence de symboles de dimension N en fonction du signal numérique utilisant un codeur convolutionnel de dimension N' dans le codeur en treillis plusieurs fois (partie entière de N/N' fois) pendant chaque intervalle de symbole de dimension N. Cela permet au codeur en treillis de produire une sortie de dimensionnalité plus élevée que celle normalement fournie par un codeur convolutionnel à dimensionnalité moins élevée. Le codeur en treillis est applicable aux transmissions télévisuelles.

Title: Ventilation stop for a sliding window or door
Inventor: ALLEN GREGORY B
IPC: E05D5/00
Filed: 1996-06-03
Granted: 2005-04-05
Abstract: A ventilation stop for limiting the length of movement of a slidable door or window sash. The ventilation stop is located in a fixed element of a window or door assembly, preferably in an interior glazing stop of a fixed sash adjacent to the slidable sash. The stop includes a recess in the glazing stop, a tab disposed in and protruding from the recess, and a hinge pin disposed in friction fit through a bore in the tab and extending into the glazing stop beyond the recess, preferably in both directions from the tab. The axes of the bore and the pin are parallel to the direction of movement of the slidable sash, permitting the tab to be turned into an interfering relationship with the slidable sash, thereby limiting the length of movement of the sash, or to be turned out of interference, thereby permitting unrestricted movement of the sash. Preferably the glazing stop is hollow, allowing for easy insertion of the pin into the tab from within the glazing stop during assembly of a window or door unit. Preferably the pin is slightly crimped near its middle to increase the frictional fit of the pin within the tab. When the crimped pin is radially oriented and held within the bore such that the included crimp angle lies at 45° from the major plane of the tab, the pin acts as a leaf spring within the glazing stop, providing alternative preferred rest positions of the tab in either the open or closed position.

Granted: 2001-07-24
Abstract: Dans un digesteur/lessiveur à marche continue, le remplacement de la classique benne, de l'étuveur, et de la cheminée à copeaux par un unique réservoir vertical a permis de simplifier grandement les structures d'alimentation. Un orifice de déversement, situé dans le fond du réservoir (11), est relié, par une pompe basse pression (28), à l'entrée basse pression d'un dispositif (30) de transfert à haute pression, lui même relié à un digesteur/lessiveur (41), soit directement, soit par le biais d'un réservoir d'imprégnation. Un dispositif de mesure (12), de préférence par l'intermédiaire d'un système (42) de séparation sous pression, destiné à maintenir une pression supérieure à la pression atmosphérique, amène les copeaux au sommet du réservoir. On dispose également dans le réservoir un premier niveau (13), fait de copeaux, et un second niveau (22) de liquide, sous le premier niveau. Un conduit, muni d'une vanne (19) à commande automatique et d'une commande de température (20) destinée à agir au moins partiellement sur la vanne, permet d'injecter de la vapeur (17) dans un volume compris entre le sommet du réservoir et le second niveau. Un régulateur de niveau (23), qui commande l'alimentation du réservoir en liquide, est relié à l'orifice de déversement à basse pression depuis le dispositif de transfert à haute pression. Entre le second niveau et l'orifice situé dans le fond du réservoir, la section transversale diminue de plus de 50 %. Selon une autre réalisation, la pompe peut également relier le fond du réservoir à un ou plusieurs digesteurs/lessiveurs en discontinu.

Abstract: Un système d'interrogation de bases de données comprend un système d'aide d'interrogation permettant à l'utilisateur de n'entrer que les interrogations à la fois syntaxiquement et sémantiquement correctes (et pouvant être traitées par un générateur de langage d'interrogation structuré (SQL) afin de produire un SQL sémantiquement correct). Le fait d'utiliser des cadres de dialogue permet à l'utilisateur d'entrer une interrogation dans un langage intermédiaire de type anglais facilement compris par l'utilisateur. Un système expert d'interrogation contrôle l'interrogation à mesure qu'elle est formulée, et à l'aide d'informations relatives à la structure de données, il empêche l'utilisateur d'élaborer des interrogations sémantiquement incorrectes en interdisant des choix dans les cadres de dialogues, lesquels créeraient des interrogations incorrectes. On a également prévu un générateur SQL, il utilise un ensemble de transformations et de substitutions de configuration afin de convertir le langage intermédiaire en une interrogation SQL syntaxiquement et sémantiquement correcte. Le language intermédiaire peut représenter des interrogations SQL complexes tout en étant simultanément facile à comprendre. Ledit langage intermédiaire est également conçu pour être converti facilement en interrogations SQL. Outre le système d'aide d'interrogation et le générateur SQL, on a prévu une unité de gestion permettant à un administrateur d'ajouter une couche conceptuelle à la base de données sous-jacente, facilitant à l'utilisateur l'interrogation de la base de données. Cette couche conceptuelle peut contenir différents noms de colonnes et de tables, des voies spécifiant des raccordements classiques et complexes, des définitions de tables et de colonnes virtuelles, ainsi que des limitations d'accès utilisateur.

Abstract: In a rotary atomizing head type coating machine, paint mist is prevented from depositing on a shaping air ring and synthetic resin cover. Shaping air ring (21) is constituted by an inner ring (22) of a metallic material, an outer ring (23) of an insulating synthetic resin material, and a shaping air outlet hole (24) provided at the fore ends of the two rings (22) and (23). The inner ring (22) has its base end (22A) electrically connected to an air motor (2), and provides an annular repulsion electrode (25) at its fore end (22B). This annular repulsion electrode (25) induces strong positive discharges, thereby attracting clouds of negative ions, and preventing paint deposition on and contamination of the shaping air ring by a phenomenon of homopolar repulsions between clouds of negative ions and negatively charged paint particles.

Granted: 2005-03-15
Abstract: A CDMA communication method capable of providing a multi-rate user with high quality transmission using a spreading sequence selected from sequences which consist of multilayer sequences arranged in a hierarchical tree structure. A higher level sequence C16(1) and its inverted sequence C16(1) are included in its lower level sequences {C32(1), C32(2)} and {C64(1), C64(2), C64(3), C64(4)}, for example, and a sequence from a higher level is selected to transmit a higher rate data: The C16(1) is used to transmit data whose peak rate is twice the peak rate of the data transmitted using its lower level sequences {C32(1), C32(2)}, and four times (= 2 2) that of the data transmitted using the sequences {C64(1), C64(2), C64(3), C64(4)}. The C16(1), however, cannot be selected if any one of its lower level sequences {C32(1), C32(2)} and {C64(1), C64(2), C64(3), C64(4)} are already being used. This makes it possible for all the spreading sequences of simultaneous multi-rate users to be orthogonal at any transmission rate.

Title: Resource sharing for book-ahead and instantaneous-request calls
Inventor: WHITT WARD
IPC: H04L12/56
Filed: 1997-10-16
Granted: 2001-05-22
Abstract: Because it is difficult to provide adequate quality of service to large-bandwidth calls in integrated-services networks, service providers may allow some customers to book ahead their calls.  The present invention provides a scheme  resource  sharing among book-ahead calls  (that announce their call initiation and holding times upon arrival) and non-book-ahead calls (that do not announce their holding times and enter service immediately,  if admitted).   The basis for this sharing is an admission control algorithm in which admission is allowed if an approximate interrupt probability (computed in real time) is below a threshold.  Simulation experiments show that the proposed admission control methodology is superior to alternative schemes that do not allow interruption, such as a strict partitioning of resources.

IPC: B29C65/00
Filed: 1996-06-07
Granted: 2002-08-06
Abstract: La présente invention concerne un procédé de solidarisation consistant à diriger un rayonnement électromagnétique, non cohérent et polychrome (14), via un matériau (16) transparent au rayonnement, sur un matériaux absorbant (18) qui absorbe le rayonnement avec dégagement de chaleur. Cette chaleur sert à chauffer une ligne de liaison (20) constituée entre le matériau transparent (16) et un substrat (18) de manière suffisante pour solidariser le matériau transparent (16) et le substrat (18). Un filtre de rayonnement (22), réalisé dans le même matériau que le matériau transparent, permet de réduire sensiblement l'absorption (et la chaleur) indésirable dans le matériau transparent (16). La focalisation du rayonnement, son masquage, le refroidissement du plastique transparent, le séchage du composant de la ligne de liaison, le soudage double passe et une pression supplémentaire sur la ligne de liaison contribuent à améliorer la solidarisation des objets ainsi fabriqués. L'emploi d'unités mobiles à double source de rayonnement permet d'obtenir une vitesse de soudage d'au moins 5 ou 6 supérieure à celle obtenue avec une unité mobile à une seule source de rayonnement.
