Title: Procede et dispositif utilisant des ultrasons pour souder a demeure une ebauche constituee d'un materiau de forme circulaire
Inventor: ANDERSSON ANDERS
IPC: B29C65/08

Abstract: Dans la fabrication des contenants de conditionnement, par exemple des bouteilles plastique obtenues par soufflage, une ébauche circulaire est, dans certains cas, soudée à demeure à l'extrémité d'une partie en forme de manchon. Il est avantageux, notamment sur le plan énergétique, de procéder au soudage par ultrasons. En l'occurrence, il s'avère que la zone centrale de l'ébauche circulaire absorbe l'énergie des ultrasons dans une telle mesure qu'elle se déforme ou se rompt. La présente invention concerne un procédé d'utilisation des ultrasons pour souder à demeure une ébauche circulaire (13) sans se heurter aux inconvénients précités. Les oscillations résultants des ultrasons sont atténuées par une stabilisation mécanique de la zone centrale de l'ébauche (13), cette stabilisation étant réalisée à l'aide d'un vide et d'un motif en relief (18) produit dans la partie centrale de l'ébauche circulaire. Le dispositif d'utilisation d'ultrasons pour souder à demeure l'ébauche circulaire (13) en place comporte une butée antagoniste (12) par rapport à la surface de travail qui maintient l'ébauche circulaire, la surface de travail faisant partie intégrante d'une chambre à vide, et un dispositif de maintien de la région centrale de l'ébauche circulaire au cours du cycle de soudage.

Abstract: Architectures for a synchronous transport network of a telecommunications system using transparent transport capabilities are presented. The telecommunications network comprises a pair of transparent multiplexers (TMuxs) connected over a bidirectional high speed span for transparently transporting high rate traffic. Each TMux consolidates traffic from a plurality (I) of linear systems or a plurality of bidirectional self-healing rings, each ring (K i) having a ring rate Ri and at least two nodes (A i, B  i). In another configuration, each TMux subtends a plurality of rings, such TMuxes being adapted for connection as ring nodes in a high-speed ring. The upgrades obtained with TMuxes in both the linear and ring configurations provide for per span relief for fiber exhaust where no changes to the existing systems are desired. As well, the bandwidth of an existing system may be increased on a per-span basis or the equipment count may be reduced.

Title: Method and apparatus for adjacent service area handoff in communication systems
Inventor: SCHIFF LEONARD N
IPC: H04W16/24
Filed: 1997-09-23
Granted: 2008-06-03
Abstract: A handoff technique in which system users detect transitions in service between a current service area (B10, S4) and an adjacent service area (B2, S5), and request a forward link channel in the new service area (B2, S5) when a detected signal strength for the new service area exceeds predetermined threshold levels. The forward communications link in the current service area is maintained until the strength of the new service area signal (B2, S5) reaches a certain level and appropriate channel quality is confirmed, as based on various known criteria. Typically, service area transitions are detected using the signal strength of pilot or paging signals associated with service areas, which are used to determine a relative signal strength of new service area signals. Pilot signal level adjustments used to counter roll-off effects are detected and compensated for in comparing signal levels.  To minimize the burden on system resources, new service area signals are not selectable until a minimum time has passed, or a minimum change in energy from a prior pilot signal is detected. In addition, communications using the previous service area can be dropped almost immediately upon engaging the new service area.

The first component of the bicomponent fibers has a melting point which is at least about 50 °C lower than the melting point of the second component. The bonded carded web has a plurality of interfiber bonds. The web also contains a binder at a level of from about 10 to about 50 percent by weight, based on the weight of the bonded carded web, in which the amount of binder at the second side is less than the amount of binder at the first side and the amount of binder at the first side is sufficient to permit multiple attachments of the first side of the bonded carded web to and releases from the hooks without significant distortion of the fibers at the first side. The present invention also provides a method of preparing a loop material suitable for use in a hook-and-loop fastening system.
