Abstract: A method of determining a restoration route (or an additional route) in a fully or partially meshed communications network of nodes, in which the step of sending a route-finder signature from a node to a neighbouring node on one of a plurality of spare links of a span to the neighbouring node comprises the prior substeps of: determining whether the node has a higher or a lower ranking network node identity than that of the neighbouring node; and if it is higher ranking, sending the route-finder signature on the spare link corresponding to the lowest ranking of the node ports associated with said span; or if it is lower ranking, sending the route-finder signature on the spare link corresponding to the highest ranking of the node ports associated with said span. Any contention which occurs because the two nodes connected to a span make provisional allocation for one or more links simultaneously to different restoration routes is dealt with by a contention protocol in which the higher ranking of the two nodes knows that its provisional allocation will be confirmed, and the lower ranking of the two nodes knows that it must send a backtrack signature for the capacity that is not available.

Title: Linear indexing apparatus with selective porting
Inventor: SHY PERRY C
IPC: E21B23/00
Filed: 1998-01-21
Granted: 2002-11-26
Abstract: A  Linear  indexing  tool  is  operably  supportable  on  a tubing string in a subterranean wellbore and has a tubular housing structure within which a tubular mandrel is coaxially and slidably disposed.  An indexing structure is operable by tubing pressure to sequentially drive the mandrel through a plurality  of  axial  travel  increments  in  response  to  a corresponding successive plurality of tubing pressure forces exerted  on  the  indexing  structure.    Pressure  diversion apparatus is operative to permit flow of pressurized fluid from within the housing structure to an external, pressure-actuatable device,  such as a packer, only after the mandrel has been driven through at  least  two of its  axial  travel increments.  Accordingly, the internal tubing pressure may be elevated to a test level thereof, thereby driving the mandrel through its first axial travel increment,  without actuating the external device.   A subsequent tubing pressure reduction and  re-elevation  may  then  be  used  to  index  the  mandrel through another axial  travel  stroke  to cause  the  internal tubing pressure  to  be  operably  diverted  to  the  external device.

Abstract: La présente invention concerne un cathéter (10) faisant pénétrer au moins une électrode (12) dans une veine pour y effectuer une procédure peu traumatisante utilisant une énergie de radiofréquence (RF). On introduit le cathéter (10) dans le corps du patient et on place ledit cathéter dans la section de veine à traiter. L'électrode (12) irradie l'énergie de radiofréquence vers la veine: le tissu veineux avoisinant se réchauffe et commence à rétrécir. On peut utiliser un élément ovale (32) pour limiter le rétrécissement de la veine à un certain diamètre déterminé par ledit élément ovale (32). L'électrode (12) peut rester active jusqu'à ce que l'on obtienne un rétrécissement suffisant de la veine. L'étendue du rétrécissement de la veine peut être détectée par fluoroscopie. Après traitement d'une première section de la veine, on peut déplacer le cathéter (10) et l'électrode (12) par intraluminescence vers d'autres sections de la veine à traiter jusqu'à ce que toutes les sections et valves veineuses voulues aient pu être réparées et reprendre ainsi leurs fonctions normales.

Abstract: A single seater snowmobile type recreational vehicle and a steering assembly for such as vehicle is described herein. The recreational vehicle includes a longitudinal frame, a suspension mounted to a rear portion of the frame, an endless track rotatably mounted to the suspension, an engine mounted to the frame and associated to the endless track to selectively rotate the endless track about the suspension thereby allowing displacement of the vehicle. The recreational vehicle also includes a steering assembly provided with a handlebar portion mounted to the frame and pivoting about a first pivot axis, a fork portion mounted to the frame and pivoting about a second pivot axis, a direction bar having a proximate end linked to the handlebar portion and a distal end linked to the fork portion, the direction bar being offset from the first and second pivot axis. A rotation of the handlebar portion thereby causes a rotation of the fork portion. The direction bar therefore allows the first and second pivot axis to be longitudinally spaced apart. The fork portion has a distal end configured and sized to receive a single ski.

Abstract: A zeolite-based ethylbenzene process which is suitable for retrofiaing aluminum chloride-based ethylbenzene plants. The process involves alkylating benzene with ethylene in an alkylation zone in the presence of zeolite beta or Y or an MCM zeolite so as to produce an alkylation product mixture containing benzene, ethylbenzcne, and polyethylbenzenes which can be separated in the aromatics recovery (distillation) stage of an aluminum chloride-based plant. The polyethylbenzenes are subsequently contacted with benzene in a transalkylati on zone using zeolite beta or mordenite or Y so as to produce a transalkylation product mixture which is also separable in the aromatics recovery stage of an aluminum chloride-based plant.

Abstract: A polymer is formed from monomers including a zwitterionic monomer, a cation ic monomer and a hydrophobic termonomer. The polymer may be cross-linkable. The polymer may be coated onto a surface from a liquid coating composition followed by contacting the coated surface with heparin. The double coated substrates have improved heparin activity over extended periods as compared to heparinised surfaces which are commercially available. Other anionically charged mucopolysaccharides may be used. The polymers may also scavenge heparin from treated blood to avoid use of potentially toxic heparin inhibitors. Preferably the terpolymer is formed from 2-methacryloyloxyethyl-2-(trimethylamonium)phosphate inner salt, choline methacrylate and n-dodecyl methacrylate.

Abstract: A process for the preparation of a catalyst useful for conducting carbon monoxide hydrogenation reactions, especially a Fischer-Tropsch catalyst, use of the catalyst for conducting such reactions, especially Fischer-Tropsch reactions, and the composition produced by said process. In the preparation of the catalyst, a solution of a multi-functional carboxylic acid having from about 3 to 6 total carbon atoms, preferably about 4 to 5 total carbon atoms, is employed to impregnate and disperse a compound or salt of rhenium and a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron Group metal such as iron, cobalt, or nickel onto a refractory inorganic oxide support, e.g., titania. The rhenium, which need be present only in small amount permits full and complete reduction of the catalytic metal, or metals, dispersed by the acid. Higher catalyst activitie s with lower rhenium loadings are thus achieved than in previous preparations where higher concentrations of rhenium were required to both effectively disperse, and reduce the catalytic metal, or metals, during the preparation. Surprisingly, as little as about 1/10 of the rhenium is required to accomplish the reduction promotion where the dispersion is effected with the acid.
