Title: Gaseous fuel system for bi-fuel engines
Inventor: GIBSON RICHARD D
IPC: F02M21/02
Filed: 2001-10-17
Abstract: A gas fuel system for a bi-fuel engine includes an injector block assembly that supports gas fuel injectors between an injector block and an inlet header. The block assembly may be mounted beside or behind the engine remote from the engine intake ports where gasoline fuel or gaseous fuel (gas) may be injected for powering the engine. The block assembly connects the injectors through individual distribution lines with separate port openings of an adapter plate mounted between the air intake manifold and the engine intake ports to provide for injection of gas to the intake ports from the remote location. Mounting of the injectors in the remote block assembly, which feeds the adapter, avoids changes to a developed gasoline fuel system in the engine, thus reducing development and production costs. The block assembly may also be modified to use other available gas injectors without affecting the conventional engine components.

Title: Manhole restraining system for venting out explosive gases in a manhole
Inventor: POOSTI SA ID S
IPC: E02D29/14
Filed: 2001-11-27
Abstract: A manhole restraining system used for venting out explosive gases in a manhole caused by an explosion. The manhole restraining system comprises a support frame, a two inch thick plate member positioned on top of the support frame, a plurality of restraining assemblies and a manhole cover for covering the manhole. The support frame and the plate member are embedded into a street and positioned above the manhole, where openings are aligned with the manhole. Three retaining assemblies are positioned on opposite sides of the manhole cover. Each retaining assembly includes a rod, a stop plate, a coil spring, a support plate and a nut. The rod extends downwardly through the dirt and the horizontal concrete base ledge, where the stop plate, the coil spring, the support plate and the nut are positioned and secured to the other end of the rod. A PVC pipe is provided with the rod for allowing the rod to move smoothly up and down without any friction. When an explosion occurs in the manhole, the pressure caused by the explosion lifts the plate member from a seated position on the main support frame above the manhole which in turn upwardly moves the rod, the stop plate, the coil spring, the support plate and the nut, where the explosive gases are vented out between the plate member and the main support frame. The stop plate, coil spring, the support plate and the nut absorb most of the energy caused by the explosion. The spring means soften the impact and assist in bringing the plate member back down to the main support frame in alignment with the manhole.

Title: Procede de commande de surcharge pour reseau a commutation de paquets
Inventor: MA JIAN
IPC: H04L47/32
Filed: 1999-03-18
Abstract: Cette invention concerne un procédé permettant de commander une surcharge dans un réseau à commutation de paquets, en particulier dans un réseau où le protocole de contrôle de transmission (TCP) fait office de protocole pour couche de transport. Pour informer aussi tôt que possible la source de trafic que le réseau est en passe d'être surchargé ou congestionné, on n'autorise la transmission d'accusés de réception que si le nombre de jetons disponibles suffisant. Un tel dispositif à base de jetons calcule le nombre de jetons en fonction de conditions des ressources telles que la capacité tampon restante vers l'aval dans un noeud du réseau. Ce système évite de devoir déterminer un seuil d'occupation du tampon oui un taux de retard des accusés de réception. Ces accusés de réception sont étroitement fonction des ressources momentanées du réseau et ne sont pas tributaires des caractéristiques du trafic de données. Par voie de conséquence, la commande de surcharge est bien adaptée à sa fonction.
