Abstract: Le procédé de l'invention permet de doubler la fréquence d'un premier signal optique d'horloge approximativement sinusoïdal ayant une fréquence f0 utilis ant des moyens tout optiques. Le procédé utilise un miroir optique non linéaire (NOLM) comme modulateur optique, ce modulateur NOLM étant commandé par ledit premier signal d'horloge à f0 pour moduler un deuxième signal continu introduit sur l'entrée signal dudit NOLM. A la sortie du NOLM, selon le proc édé de l'invention, on récupère un signal modulé à la fréquence 2f0. Avantageusement, le procédé de l'invention utilise deux longueurs d'onde pou r lesdits premier et deuxième signaux, ces deux longueurs d'onde ayant sensiblement la même vitesse de groupe dans ledit NOLM. Dans une variante importante, la puissance crête à crête Pcc du premier signal de contrôle est  bien inférieure à la puissance P.pi., qui est nécessaire pour maximiser l'effet d e commutation du NOLM sur ledit deuxième signal. L'invention concerne également un régénérateur de solitons utilisant le procédé de doublage optiq ue. Applications dans le domaine des télécommunications sur fibre optique, notamment par solitons.

Abstract: A work fixture brake includes a first block and a second block and a brake disc. The first block has a first axis of rotation passing therethrough and a first friction pad fixed thereto. The second block is axially juxtaposed the first block and is pivotably connected thereto at a second axis of rotation. A second friction pad is rotatively fixed to the second block. A brake disc has a first side facing the first friction pad and an oppositely disposed second side facing the second friction pad. The brake disc is approximately centered on the first axis of rotations. Means for axially separating the first block from the second block are disposed therebetween. The means are responsive to a rotative force against the second block in a direction which would induce rotation about the second axis of rotation. The means thereby axially separates the first friction pad and the second friction pad, in turn releasing the brake disc.

Abstract: A method for isolating subterranean formations or zones intersected by a single wellbore is provided. The method comprises perforating a zone intersected by the wellbore and pumping a sealing means into the wellbore to seal against the side of the casing above and below the perforations to prevent communication from the zone into the wellbore after the casing has been perforated. The method further comprises fracturing the zone through the perforations prior to sealing and thus isolating the zone. Other zones thereabove are likewise perforated, fractured, sealed and thus isolated by pumping sealing means into the wellbore to seal the casing adjacent the perforations to prevent communication from the affected zones into the wellbore.

Abstract: An umbrella-like antenna reflector assembly (12)  for use on an orbiting spacecraft  (14).   The reflector (12) has a main rib (18) and a plurality of secondary ribs (20) each connected to a hub assembly (24)  by a respective hinge mechanism  (40)  such that activation of the hub assembly (24) causes the reflector (12)  to move between collapsed and opened configurations. The reflector (12) further has a mesh member (22) attached to the ribs (18, 20).  A deployment boom (16) connects the main rib (18) of the reflector (12) to the spacecraft (14).  The deployment boom (16) is operable with the main rib (18) and the spacecraft (14) to move the reflector (12) between a collapsed and stowed configuration proximate the spacecraft (14) and an open and deployed configuration outside the spacecraft (14). The storage profile is sufficiently slim to permit launching of a 6-25 meter diameter reflector attached to a full-sized spacecraft on one or more commercially available launch vehicles without the need for mid-rib hinges.   A feed assembly  (26)  is connected to the spacecraft (14).  The feed assembly (26) is offset from and operable with the mesh member (22) of the reflector (12) when the reflector (12) is in the opened and deployed configurations to receive and/or transmit radio frequency energy therefrom.

Title: Arcuate absorbent article with laterally extending flaps having longitudinal stretch
Inventor: TAYLOR JOANN LEE
IPC: A61F13/514
Filed: 1997-03-12
Granted: 2002-12-24
Abstract: Absorbent articles, particularly sanitary napkins, having elastically extensible, laterally extending flaps are disclosed. The flaps are further provided with a means for attaching them to a wearer's panty. At least a portion of the elastic extensibility has a vector component in the longitudinal direction. This longitudinally oriented elastic extensibility provides a contractive force which causes the absorbent article to assume an arcuate shape that more readily conforms to the wearer. Further, the extensibility allows the flaps to extend and contract with the edges of the leg openings of the wearer's panty so the flaps are more reliably adhered to the panty.

Abstract: L'invention concerne un procédé permettant de faire fonctionner un réseau dans lequel le raccordement est coupé entre d'une part l'approvisionnement en services et le paiement pour lesdits services, et d'autre part le point de terminaison du réseau de télécommunication auquel est fourni le service. Pour remédier à ce problème, une association est maintenue entre l'approvisionnement/la facturation et un appareil faisant partie du matériel de télécommunication, quel que soit le point où ledit appareil est raccordé au réseau. Ceci permet à un consommateur d'obtenir un service à n'importe quel point du réseau, et à la société d'exploitation de télécommunication de rationaliser les processus d'approvisionnement, de facturation et de recueil d'argent. La société garde un compte pour un appareil spécifique. On peut créer le compte en transmettant directement à la société une demande de service qui contient des informations identifiant uniquement ledit appareil et des informations lui permettant d'envoyer une facture au consommateur. La société établit éventuellement une relation avec une entreprise de cartes de crédit, qui paiera les services fournis à l'appareil.

Abstract: A wheel driven suction nozzle having an upper body attached to an under body. An opening is formed at a front of the upper body which provides access to a suction cavity. An agitator covered with a fluff material is removably rotatably mounted within the cavity and extends partially out a bottom of the under body to clean and shine bare floors. A cover is hingedly mounted to the upper body and movable between an open position which provides access to the cavity and allows for removal of the agitator, and a closed position which covers the cavity and prevents removal of the agitator. A cogged front pulley is attached to one end of the agitator. A cogged belt is driven by a rear cogged pulley and engages the front pulley whereby rotation of the rear pulley rotates the agitator. A front gear is rigidly connected to the rear pulley and engages a rear gear which is rigidly connected to an axle shaft. A pipped wheel is attached to each end of the axial shaft whereby rotation of the wheels rotates the rear gear which, in turn, rotates the front gear, the rear pulley and thus the agitator.

Abstract: A device for determining the quality of an output signal to be generated by a signal processing circuit including a radio link with respect to a reference signal is provided with a first series circuit for receiving the output signal and with a second series circuit for receiving the reference signal and generates an objective quality signal by means of a combining circuit coupled to the two series circuits, whereby a scaling circuit is disposed between the two series circuits for scaling at least one series circuit signal. The poor correlation between said objective quality signal and a subjective quality signal to be assessed by human observers can be considerably improved by disposing a discounting arrangement inside the combining circuit, which discounting arrangement should be coupled to the scaling circuit for receiving a comparison signal and for discounting said comparison signal while generating the quality signal.
