Title: Hazardous or toxic waste material storage apparatus and associated method
Inventor: CURIEL YORAM
IPC: B65F1/16
Filed: 1996-04-11
Abstract: The hazardous or toxic waste material storage apparatus includes a flexible inner container (2) for receiving the hazardous waste material or toxic waste material with the inner container (2) having at least one zone of expansion (24) which is substantially more expandable than other portions of the inner container (2). The inner container (2) which holds the hazardous or toxic waste material is sealed and disposed within an outer container (40) which is preferably composed of a flexible material. The inner container (2) preferably occupies less than the full volume of the outer container (40) so as to permit relative movement therebetween. A sealing disc (70) may function as a closure for the outer container (40) and may be mechanically engaged with portions of the outer container (40) to retain the same in position. In one embodiment, an inflatable member (150) is disposed within the outer container (40) so as to reduce the amount of unoccupied space within the outer container (40).

IPC: H04L47/22
Filed: 1997-11-12
Abstract: To realize the traffic control for controlling congestion in an ATM switchboard and assuring the throughput of VCs using the same output port.  A buffer occupancy value measuring section measures the queue length of each of the output port buffers and stores the data in a buffer occupancy value table. A back-pressure outputting section outputs a transmission restart signal when a queue length in the buffer occupancy table is equal to or less than a fist threshold, a transmission control signal when the queue length is between the first threshold and a second threshold, and a transmission stop signal when the queue length is equal to or more than the second threshold as back pressure signal respectively. A cell transmission control section transmits an ATM cell without comparing a transmission time with the present time when the instruction of a back pressure signal corresponding to a destination port indicates "restart" and transmits an ATM cell only when the transmission time is earlier than the present time if the instruction indicates "control".

Title: Accroissement de la retention de geo2 durant la production d'articles en verre
Inventor: BURKE GERALD E
IPC: C03C3/06
Filed: 1996-09-04
Abstract: Le procédé faisant l'objet de cette invention sert à former un article en verre au SiO¿2? dopé par GeO¿2? en déposant des particules de verre, afin de former une préforme poreuse, puis en séchant et en frittant cette préforme poreuse. Un précurseur de SnO¿2? est également présent dans le flux de réactifs utilisés pour former les particules, pour que la réaction produise des particules de verre qui contiennent GeO¿2?, SiO¿2? et SnO¿2?. La présence de SnO¿2? dans les particules réduit la réaction de GeO¿2? avec le chlore pour former GeCl¿4? pendant l'étape de séchage. Le GeCl¿4? qui se serait formé soit ce serait échappé de la préforme poreuse soit aurait amené GeO¿2? à se redéposer dans une partie indésirable de la préforme. La rétention de GeO¿2? dans l'article en verre est par conséquent accrue.

Abstract: L'invention concerne un récepteur comportant un démodulateur (222) cohérent et un démodulateur (222) non cohérent. Lorsqu'il y a une forte certitude d'estimation de voie, le démodulateur cohérent (408, 409, 425, 412) est mis en application (400, 418). Lorsqu'il y a une faible certitude d'estimation de voie, le démodulateur non cohérent (422, 421) est mis en application. Un microprocesseur commande le procédé de sélection et émet également un signal permettant de mettre en application le démodulateur non cohérent dans les cas où une démodulation non cohérente pourrait être plus appropriée qu'une démodulation cohérente. Par exemple, un tel cas pourrait se présenter immédiatement après le transfert d'une station mobile, d'une station de base source à une station de base cible.
