Abstract: A dual  valve  apparatus  enables  quick measurement  of pressure contained within a housing.  The housing has a main body, a check valve housed in the main body and a cover whose removal renders the check valve accessible.  The check valve is normally compressed against a check valve seat to provide a first seal that prevents leakage of the pressure.   The dual valve apparatus includes a modified cover, a valve body and a valve stem.  The modified cover defines first and second bores axially offset from and in communication with one another.  The first bore is at least partially threaded.  When the modified cover is secured to the main body, the second bore is aligned with the check valve.  The valve body accommodates a valve bore from its protuberant end to its threaded end.  The protuberant end is shaped to mate with a female portion of a quick connect coupling.  The threaded end screws into the first bore of the modified cover.  Movable within the bores, the valve stem at its head end is normally compressed against a valve seat formed within the protuberant end of the valve bore to provide a second seal that further prevents leakage of the pressure.          Mating the female portion to the protuberant end of the dual valve apparatus causes the valve stem to move away from its seat.  The valve stem in turn unseats the check valve thereby providing access to and enabling measurement of the pressure.

Inventor: BURKWALD SUSAN KAY
IPC: G06F9/44
Filed: 1998-11-25
Granted: 2003-12-16
Abstract: A software visualization technique allows a software application or portfolio tobe visually analyzed to determine the extent and depth of problems raised when converting an existing software application or portfolio to make application- orportfolio-wide revisions, such as those needed to respond to the year 2000 problem or the conversion to Euro currency. The software visualization technique first generates or inputs statistical data on a number of different software metrics and statistics about the conversion process, such as the data or currency dependent lines of program code, the types of affected code lines, and the sizes and complexities of the systems, subsystems and programs of a software application and of the applications forming a portfolio. These metrics and statistics are then used to alter the appearance of various views of the software application, systems, subsystems, programs individual lines of the programs generated by various visualization tools of the software visualization technique. By interacting with the various views, an analyst can quickly and cost-efficiently determine which portions of the application or portfolio need revision, and the optimal methods for implementing the revisions.

Granted: 2001-06-12
Abstract: La présente invention concerne un système d'alimentation électrique particulièrement conçu pour une utilisation avec un dispositif de précipitation électrostatique. Ledit système fournit en effet un courant continu pratiquement dépourvu d'ondulations, ce qui améliore l'usage du dispositif de précipitation. L'alimentation accepte en entrée un courant alternatif triphasé et transforme ledit courant alternatif en courant continu haute tension ayant un taux d'ondulations de tension minimum en sortie. L'alimentation inclut un transformateur multiphase avec trois bobinages primaires, chacun desdits bobinages primaires étant associé avec une paire de bobinages secondaires. Les bobinages primaires peuvent être connectés aussi bien en delta qu'en étoile. Une unité de chacun des bobinages secondaires associés aux bobinages primaires correspondants est connectée selon une disposition en delta. Le reste des unités des bobinages secondaires est connecté en étoile. Le fait que la sortie alternative respective de chacun des bobinages secondaires est déphasée par rapport à la sortie alternative des autres bobinages secondaires produit une tension continue résultante combinée en sortie, après que les tensions continues ont été rectifiées dans une pile de redresseurs à pont triphasés pleine-onde, qui produit une tension et un courant ayant un minimum d'ondulations et évite l'utilisation de composants supplémentaires, plus onéreux et moins fiables.

Abstract: A method and apparatus for labelling containers allows labelling of containers by wrap around labelling without applying an adhesive on the leading edge of the label. Labels are held on a label drum and moved into a label applying position while containers are fed into the label applying position. Air is blown from a first position on the label drum onto the leading edge of the label at an angle to the label drum surface and in a direction backward along the label from the leading edge to force the leading edge of the label against the container, while also minimizing the laminar flow of air under the label.  After the leading edge of the label has engaged the container, air is blown from a second position on the label drum spaced from the first position onto the label and container at an angle to the label drum surface to maintain a laminar flow of air over the label and maintain the label tight against the container during container rotation. The leading edge is maintained on the container by wet adhesion or by air which is blown onto the label and container from first and second angled positions on the side opposite the label drum. Air can also be blown from a third position on the label drum spaced from the first and second positions onto the leading edge of the label after the container has rotated almost 360 degrees to maintain the label tight against the container during the final part of the wrapping process.

Abstract: Lorsqu'un réseau effectue une pagination en employant un identificateur temporaire d'usager mobile (TMUI), la station mobile correspondante (MS) envoie une réponse. Après cela, le réseau effectue une authentification en employant une clé d'authentification correspondant au TMUI et des nombres aléatoires. Lorsqu'après authentification l'usager s'avère ne pas être autorisé, le réseau envoie une requête demandant que l'usager ne puisse plus envoyer d'identificateur individuel d'usager mobile (IMUI). Le réseau exécute alors une authentification en utilisant une clé d'authentification correspondant à l'IMUI et aux nombres aléatoires (S8-S10). Une fois que l'usager est identifié comme usager autorisé, le TMUI est de nouveau affecté. Une négociation entre le côté MS et le côté réseau permet de déterminer l'objet à cacher et le procédé de dissimulation commandant la synchronisation de début de dissimulation dans l'information à émettre. Dès qu'un appel se produit, le système lance une procédure de transfert en diversité. Lorsqu'au niveau d'une station mobile, il y a besoin d'un aiguillage, la voie concernée est commutée sur une voie par laquelle il est possible de faire un transfert en diversité. Dès qu'un autre appel se produit au niveau d'une station mobile capable de traiter simultanément une pluralité d'appels, les configurations de voies et les bandes de fréquences de communication sont rendues identiques pour tous les appels. Lorsqu'il se produit un appel au niveau d'une station mobile capable de traiter simultanément une pluralité d'appels, le système choisit les configurations de voies et les bandes de fréquences de communication pour lesquelles on peut conserver tous les appels, après quoi il y a transition vers ses voies et bandes. Il est ainsi possible de construire un système de communications mobiles permettant de transmettre différents types de données, ce qui rend un tel système apte à traiter les communications multimédia.
