Abstract: An interactive dental restoration method, a system for use between a dentist, and a dental restoration laboratory. The method includes identifying a dental restoration need in a patient; designing a preliminary treatment plan that includes design criteria for preparation of a dental prosthesis to be placed in the patient to satisfy the dental restoration need; transmitting the preliminary treatment plan via a communications network to a dental restoration laboratory; and communicating a final treatment plan, including modifications to the preliminary treatment plan where necessary, to the dentist. The system includes a computer-based dental restoration system of a network server (1610) having a database (1630), a network (1620), and at least one local computer (14). The database stores information about materials, procedures, and preparations concerning dental prostheses.

Abstract: L'invention concerne un système d'injection de poudre composé d'une chambre doseuse (2) alimentée directement par un dispositif d'alimentation de poudre classique (7) et en communication avec le canon (1) du pistolet de détonation par un conduit direct (5). Ainsi, l'onde de pression qui avance à travers le canon (1) pénètre le conduit de communication (5) et lorsqu'elle atteint le chambre doseuse (2), elle subit une expansion brusque qui interrompt l'alimentation en poudre en provenance du dispositif d'alimentation en continu (7) et produit la fluidification complète de la poudre contenue dans la chambre doseusse (2). La poudre fluidifiée est ensuite entraînée par succion dans le canon (1) où elle reste jusqu'à ce que l'onde de pression générée dans un nouveau cycle de détonation l'entraîne pour la déposer sur la surface de la pièce à revêtir.

Abstract: L'invention concerne un dispositif de commande (AGNT), un système de télécommunication (<u>SYS</u>), un procédé de commande et un poste d'abonné (<u>SS1</u>, TE, MT; <u>SS2</u>, TE, MT; <u>SS3</u>, TE; MT), dans lesquels une demande d'établissement de connexion émise par un premier poste d'abonné (<u>SS1</u>) ne peut pas être transférée à un réseau de télécommunication (NET) aussi longtemps que le second poste d'abonné (<u>SS2</u>), avec lequel l'appel devrait être établi, est occupé. Le dispositif de commande (AGNT) ne transfère la demande d'établissement de connexion au dispositif d'échange (MSC/VLR, GMSC, HLR) du réseau de télécommunication (NET) que quand le second poste d'abonné appelé (<u>SS2</u>) passe de l'état occupé à l'état d'attente. Les ressources du réseau ne sont donc pas occupées par des demandes d'établissement de connexion qui seraient rejetées du fait que le second poste d'abonné (<u>SS2</u>) est occupé. L'invention est particulièrement avantageuse quand le poste d'abonné appelant (<u>SS1</u>) utilise une fonction de recomposition du numéro pour réitérer sa demande d'établissement de connexion. Après plusieurs essais, les essais ultérieurs sont bloqués et l'appel n'est établi que lorsque le second poste d'abonné se libère. Une application particulièrement avantageuse de l'invention est le fait que le dispositif de commande (AGNT) associe le blocage des demandes d'établissement de connexion à un service d'aboutissement d'appels adressés à des abonnés occupés (AAO) mis en oeuvre dans le réseau (NET).

Abstract: A sputtering magnetron with a rotating cylindrical target and a stationary magnet assembly (22, 24*) is described, said magnet assembly (22, 24*) being adapted to produce an elongate plasma race-track on the surface of said target, said elongate race-track having substantially parallel tracks over a substantial portion of its length and being closed at each end by end portions (22'), wherein the spacing between the tracks of said race-track is increased locally to materially effect sputtering onto a substrate. The increase in spacing may be at the end portions or along the parallel track portion. The increase in spacin g may provide more even erosion of the target beneath the end portions of the race-track, provide more even coatings on the substrate, for instance.

Title: Method of liquefying microorganisms derived from biological wastewater treatment processes
Inventor: DHALIWAL HARPREET
IPC: C02F11/18
Filed: 1999-08-05
Granted: 2004-05-18
Abstract: A process for liquefying microorganisms present in biosolids, such as waste activated sludge, generated by municipal or industrial wastewater treatment plants is disclosed. The process includes the step of passing a slung of the sludge at a high pressure through a nozzle having a restricted flow area to cause liquefication of the microorganisms as they are discharged from the nozzle. The pressure drop across the nozzle preferably exceeds 12,000 psi. At least pan, of the liquefied microorganisms may be recirculated to the treatment facility to feed nutrients to the wastewater treatment process. Optionally, the liquefied microorganisms may be anaerobically converted to methane and carbon dioxide. For optimum results, the sludge is subjected to pH adjustment and/or maceration prior to being pumped through the high pressure nozzle.

Abstract: An operator for a window covering held on a roller or axle has a stationary member having a central cavity and a first bore sized and positioned so that the roller can pass through the bore into the central cavity. A release brake is positioned so that the axle or roller can pass through and be held by the release brake. An inertial ring within the central cavity of the stationary member, surrounds a coil spring which encircles the axle. A release member is provided adjacent the release brake and the inertial ring. The release member is sized and positioned so that when the release ring is in a first position the release member will not engage the inertial ring or the release brake and when the release member is moved in a selected direction the release member will engage and turn the release brake and the inertial ring. A spool is positioned within the central cavity of the stationary member adjacent the inertial ring.  A rewind spring is connected between the spool and the stationary member such that when a force acts on the spool to turn the spool in the first direction from the initial position the rewind spring will tighten and when the force is removed the spring will loosen causing the spool to return to the initial position.

The apparatus is positioned downstream of the first conveyor and upstream of the second conveyor. The apparatus comprises plural stopper arms each analogously displaceable between an abutting position, wherein the stopper arms hold elongated members from moving forward on the first conveyor, and a bypassing position, wherein the stopper arms are disposed away from the first conveyor for allowing the elongated members to move forward as displaced by the first conveyor. Plural analogously moving lower loaders wheel each have a generally circular body with a gripping surface on an outer periphery thereof. The gripping surface is adapted for abutting an elongated member. Plural analogously moving upper loader wheels are generally positioned above the lower loader wheels and have a resilient peripheral portion. Plural stabilizer wheels are idle and adapted for lying on a top surface of an elongated members at least when the elongated member is abutted against the stopper arms. The apparatus is synchronized such that the elongated member is lifted by the gripping surfaces of the lower loader wheels when the stopper arms are moved to the bypassing position, whereby the elongated member is engaged between the gripping surfaces of the lower loader wheels and the stabilizer wheels or the resilient portions of the upper loader wheels while being transferred from the first conveyor to the second conveyor.
