Title: Method of video information transmission, as well as an information carrier, a device for receiving and a device for transmitting video information
Inventor: DE HAAN WIEBE
IPC: H04N5/926
Filed: 1996-07-12
Granted: 2012-01-24
Abstract: Video information intended to be reproduced on a television screen (1) often includes additional information such as graphics information (3) or subtitles (4) in addition to the main information such as film images (2). This additional information is transmitted separately, so that the user may choose whether the additional information is to be displayed or not. In the disclosed method the transmitted video signal comprises information relating to the duration (25) for which the additional information is to remain on the display. With this method the additional information can be displayed exactly for the duration of the desired time. When a video disc or tape is used for transferring video information, this is advantageous in trick modes, such as Fast Forward.

Title: Arrangement for facilitating plug-and-play call features
Inventor: GAMBILL JANE
IPC: H04L29/06
Filed: 1997-03-20
Granted: 2000-02-08
Abstract: A telecommunications system infrastructure that facilitates easy insertion of feature software into existing such telecommunications systems and easy integration of the new calling features and their implementing software with existing features and their software. The infrastructure comprises the Lucent Technologies MMCX multimedia communications server (100) and middleware-compliant communications endpoints (101-102) executing the Lucent Technologies MMCX communications middleware (111-112). Feature-implementing software has a modular client/server construction, with feature managers (server modules, 300,350) executing on the MMCX server and feature administration agents (client modules, 303-353, 304-354) executing on the endpoints. The infrastructure provides a context service (120) and a context API(121) for registering an instance of a feature manager (a user policy, 301-302, 351-352) for each user upon that user becoming entitled to the feature, an administration API(360) for communications between feature managers and feature administration agents on the user's endpoint to customize the user's user policies for the user, and a context (a cyberspace meeting room, 200) and the context API for involving the user policies of users who are parties to a call in the call and for communicating call-related events to feature servers and other service-implementing software. Call-related events are passed to user policies involved in the call, and they are given a chance to react to the events by allowing or rejecting the events. Interactions between features are managed by having feature managers register at different priorities with the context service; higher-priority modules are serially given an opportunity to allow or reject events before lower-priority modules.

Title: Instant-on vented tank valve with manual override and method of operation thereof
Inventor: KHADIM NEIL M
IPC: F17C13/12
Filed: 1997-04-28
Granted: 2003-04-22
Abstract: An instant-on valve assembly with manual override is designed to be connected to a tank containing high pressure gaseous fuel.  The valve assembly and manual override allows the tank to be alternately closed off, vented or allows the gas in the tank to bypass the instant-on valve.  The instant-on valve assembly can be repaired or replaced without venting the tank.  The instant-on valve assembly has a main valve and a bleed valve.  The main valve has a secondary plunger that opens and closes a main orifice.  The bleed valve has a bleed valve stem that opens and closes a bleed orifice.  The main valve is slidably mounted within a housing and has a chamber at one end and a zone at another end.  Both the zone and the chamber have access to high pressure gaseous fuel within the tank.  High pressure gaseous fluid within the zone can be drained when the bleed valve stem is fully open.  The bleed valve stem is connected to a solenoid and opens upon activation of the solenoid. When the pressure within the zone is sufficiently reduced, the pressure within the chamber will cause the main valve to open by sliding into the zone.  A spring moves the main valve towards a closed position when the solenoid is deactivated.  Since the volume of the zone is relatively small, the main valve opens within one second after the solenoid is activated.

Abstract: L'invention concerne une méthode d'emballage d'articles compressibles (10), de manière réversible. L'article est tout d'abord placé dans un tube en matériau déformable (22) de telle façon que le matériau en excès se retrouve aux extrémités du tube. Une des extrémités (24) du tube est ensuite scellée. L'air contenu dans le tube est ensuite chassé par l'autre extrémité, ce qui provoque la déformation du tube autour de l'article et la compression de ce dernier. Alors que le tube est maintenu sous vide, la seconde extrémité est scellée elle aussi. Un manchon de confinement (26) est placé autour du tube scellé de façon à conserver l'article à l'état comprimé. Au moment du déballage, le manchon de confinement est retenu et le tube peut progressivement reprendre sa forme initiale au fur et à mesure que l'air y pénètre.

Title: Process for reducing the electric steelworks dusts and facility for implementing it
Inventor: ZOPPI GIANNI
IPC: C22B7/02
Filed: 1997-10-30
Granted: 2010-02-02
Abstract: The present invention relates to a process for processing the electric steelworks dusts and zinc--bearing, high-iron, oxidized materials in a low--frequency induction furnace of coreless type, resulting in: - reduction of contained iron oxides to cast iron, - concentration of non-ferrous metal oxides in fumes recovered from the process, and - formation of slag suitable for being disposed of in normal dumps. The cast iron bath, kept at high temperature and rapidly circulated by the induced currents which flow through it, constitutes the "reducing section" of the furnace, inside which the reduction takes place of the oxides of metal which constitute the feed: Zn, Pb, Cd, Fe. The bath covering layer, occupied by the feedstock (pelletized steelworks dusts, granular coal, slagging agents) constitute the oxidizing section of the furnace inside which coal is burnt yielding CO, and and vapours of Zn and other feedstock metals leaving the bath are oxidized again and turn into fumes. A proper fume collection unit collects the dusts and recovers Zn, Pb, Cd oxides concentrated to more than twice as high levels relatively to their initial concentrations at process beginning.

Abstract: La présente invention concerne un système de notification d'évènements critiques, qui surveille de façon continue les statistiques et les données de laboratoire de patients afin de détecter les évènements critiques et lance automatiquement un appel à un ou plusieurs médecins responsables, chacun d'eux ayant un récepteur alphanumérique d'appels. En particulier, on utilise un ordinateur pour avoir accès en continu aux données en temps réel et à des bases de données hospitalières multiples, qui sont mises à jour périodiquement. Elles comprennent celles relatives aux diagrammes des patients, celles correspondant à l'historique des patients et celles qui sont tenues à jour par divers laboratoires. L'ordinateur, de préférence un système d'information clinique, reçoit automatiquement certaines données ou les extrait périodiquement d'autres bases de données, qui sont relationnelles. L'ordinateur analyse automatiquement ces données, effectue la détermination d'évènements critiques et formule un message alphanumérique qui donne des informations sur la condition du patient considéré et les circonstances ayant entraîné la détection d'un évènement critique. Après avoir automatiquement extrait d'une base de données un numéro personnel d'identification ("PIN") destiné à un récepteur d'appels éloigné de chaque médecin responsable du patient, l'ordinateur établit automatiquement le contact, par modem, avec un réseau d'appel et lui fait envoyer un message à chaque médecin responsable, auquel il transmet le message alphanumérique. Ce dernier indique de préférence le nom du patient, le diagnostic, l'évènement à l'origine du message ainsi que le nom et le numéro de téléphone où joindre le personnel médical de l'hôpital qui s'occupe du patient considéré. Ce système a aussi de nombreuses applications en dehors de la médecine.
