Abstract: Setting of a bypass path upon occurrence of transmission failure, is applicable for large scale network.  A system includes  signaling  means  which  makes  judgment  whether bypassing process is performed by an own node by a bypassing process judgement means when a release message issued upon occurrence of failure, is received.  Upon judgment to perform bypassing process, computation of bypass path is requested by the path computing means.  On the basis of result of computation, bypass path is established and switched.  In the bypassing process judgment means, judgment is made whether bypassing process is performed by the signaling means or not depending upon the relationship of positions of the faulty portion and the own node.

Title: Flow control apparatus and methods
Inventor: JOHNSON MICHAEL H
IPC: E21B34/08
Filed: 1998-05-06
Abstract: The present invention provides a method for obtaining equalized production from deviated wellbores. A plurality of spaced apart flow control device are deployed along the length of the wellbore. The fluid from various zones are drawn in a manner that depletes the reservoir uniformly along the entire length of the wellbore. Each flow control device is initially set at a rate determined from initial reservoir simulations or models. The depletion rate, water, oil and gas content, pressure, temperature and other desired parameters are determined over a time period. This data is utilized to update the initial reservoir model, which in turn is utilized to adjust the flaw rate from one or more zones so as to equalize the flow rate from the reservoir. The present invention also provides a flow control device which includes an outer shroud that reduces the effect of fluid impact on the flow control device and one or more tortuous paths which carry the formation fluid into the production tubing A control unit controls the flow output from the flow control device. The control unit may communicate with surface equipment or act autonomously to take actions downhole based on programmed instructions provided to the control unit.

Abstract: A cooling bed plate transfer grid insert which is height adjustable independently of its mounting to the grid. The insert has an outer frame which is clampable to the grid and an inner frame supporting a roller'and which is clampable to the outer frame and height adjustable'relative to the outer frame so that the mounting of the outer frame to the grid need not be disturbed when adjusting the height of the roller or when replacing the inner frame and roller assembly.for repair of the insert. The inner frame is thus easily and inexpensively replaceable without the necessity of replacing the outer frame. The replaceable inner frame includes stationary bearings for the rotating roller shaft to provide improvement in wear life of perhaps about 200 per cent. Springs are provided to.allow the roller to flexibly move downwardly under load of plates being moved thereover so that each of the rollers underlying a plate bears its share of the load, but the rollers are biased to the desired unloaded height. A ramp is provided on the inner frame for deflecting the plates being transferred onto the roller and thereby eliminating or reducing "catch points" which may cause thin plates to bend. The end portions of the inserts have mating tongues and grooves allowing successive end-to-end placement of the inserts.

Title: Method for externally sizing fibrous materials
Inventor: VAUGHN WALTER L
IPC: D21H19/20
Filed: 1996-12-05
Abstract: Fibrous product is externally sized by applying to the material a basic aqueous dispersion of an interpolymer of an ethylenically unsaturated monomer and an ethylenically unsaturated carboxylic acid comonomer. The preferred dispersions which have lower initial viscosities provide dispersion/starch dilute solutions with higher viscosities and improved external sizing effectiveness. Resulting fibrous products are adequately sized and exhibit excellent printability and strength properties.

Title: Anti-tip assembly for power wheelchair
Inventor: PULVER DALE A
IPC: A61G5/04
Filed: 1998-06-05
Abstract: The power wheelchair includes an anti-tip assembly extending from the frame. The anti-tip assembly includes a plate secured to the frame via a dampening mechanism. A first arm extends from the plate and is mounted thereto for a limited amount of relative movement. A grounding engaging wheel disposed on a distal end of the arm is urged toward the ground surface by a biasing spring interposed between the arm and the plate. As the wheelchair begins to tip, anti-tip or resistive forces are generated initially by the biasing spring. This resisting force continues in a linear fashion until relative movement between the arm and the plate ceases. Thereafter, further resistive forces are provided by the dampener as movement of the plate toward the frame is resisted in a linear fashion by the dampener.

Title: Method of oxidizing alkyl-5-formyl valerate to monoalkyl adipate
Inventor: LANE SAMUEL LIVINGSTON
IPC: C07C69/44
Filed: 1998-03-24
Abstract: An improved method for the selective oxidation of alkyl-5-valerate to monomethyl adipate (e.g., methyl-5-valerate to monomethyl adipate). By performing the air oxidation at high pressure (i.e., > 10 bars air and preferably 35 to 65 bars) and relatively moderate temperature (i.e., 20 to 120 ~C) in the absence of a catalyst, commercial rates of conversion can be sustained at optimum selectivity to the desired product. Such a high pressure process is particularly amenable to continuous operating the oxidation reactor at optimum selectivity at the expense of conversion per pass followed by product separation and recycle of reactants.
