Title: Virtual private networks and methods for their operation
Inventor: HURREN ALAN JAMES
IPC: H04L12/56
Filed: 2000-01-20
Abstract: In methods and apparatus for routing packets through a communications network, a respective distinct broadcast address is assigned to each of a plurality of distinct sets of virtual ports. No virtual port belongs to more than one of the distinct sets. A respective egress address is assigned to each packet entering the network via an ingress virtual port. The respective egress address corresponds to a respective destination address of the entering packet when a correspondence between the destination address and an egress address is known. When no correspondence between the destination address and an egress address is known, the respective egress address is a broadcast egress address corresponding to the set comprising the ingress virtual port. The packet is routed according to the respective egress address. The routing is restricted to virtual ports belonging to the distinct set of virtual ports that includes the ingress virtual port. The distinct sets of virtual ports and their associated broadcast addresses define isolated virtual private networks within the network. Each physical port of the network may map one-to-one onto a corresponding virtual port, or may map onto a corresponding plurality of virtual ports, in which case the each virtual port of the plurality is associated with a respective distinct combination of a physical address of the physical port and a respective virtual network identifier.

Patent CA-2306059-A1 (CA)
Inventor: REITTINGER PETER W
IPC: E21B47/04
Filed: 2000-04-18
Abstract: A system for evaluating multiphase fluid flow in a wellbore. Two distinct AC signals are injected into a fluid. One AC signal originates from an electrode in ohmic contact with the fluid, and the other AC signal originates from an electrode capacitively coupled to the fluid. The geometric factors between the electrode pairs are selected to distinguish between different constituents within the wellbore fluids. The output impedance of the ohmic transmitter is low so that the AC signal from the capacitive transmitter is shunted to signal ground in conductive fluids. A single detector can measure the fraction of conductive water covering the detector electrode as well as the dielectric constant of an oil and gas mixture. Arrays of such detector electrodes can measure the holdups and velocities of the constituent fluids in a flowing multiphase fluid.

Title: Belt drive for a belt conveyor
Inventor: EPP DWAYNE S
IPC: B65G41/00
Filed: 2000-06-19
Abstract: A belt conveyor has a continuous belt mounted within a tube for supporting a transportation run of the belt with the return run of the belt being guided along an underside of the tube. An undercarriage supports the tube and causes raising and lowering movement of at least the discharge end of the tube. A  drive roller is driven by a drive input with each mounted on the undercarriage at positions thereon which remains substantially stationary as the tube is raised so that the input remains in a fixed position as the tube is moved in said movement and so that the drive roller is fixed relative to the input drive member to receive drive therefrom without necessity for adjustment as the duct is moved. The drive roller is spaced from the return run of the belt on the underside of the tube and the belt includes a divergent portion having two runs extending from the return run to and from the drive roller to receive drive therefrom. Tension in the belt is compensated by an arrangement in which at least one idler roller is provided at the drive roller around which the belt passes so as to wrap the belt around the drive roller, the idler roller being adjustable in position relative to the drive roller to effect tensioning of the belt. The position of the idler roller is adjusted by a hydraulic cylinder attached to an accumulator of hydraulic fluid arranged to receive a fluid at a predetermined pressure such that the idler roller is pulled in a direction to apply tension to the belt at a predetermined force thus maintaining a predetermined tension in the belt while accommodating changes in belt length.

Inventor: DUBE JONATHAN
IPC: C01D15/08

Abstract: The invention relates to a method for the neutralization and the recycling of spent rechargeable lithium batteries, particularly lithium metal polymer batteries, comprising at least one negative electrode active material, a separator, an electrolyte, one positive electrode active material, a current collector and a cell casing. After mechanical dismantling of the casing, the method involves three distinct possible processes, i.e., digestion into a solvent, incineration, or molten salt oxidation. The three processes include the steps of mechanically dismantling the batteries to remove the metal casing and the electric hardware as scrap, lowering the temperature of the free electrochemical cells (ECs) below ambient temperature., and shredding the ECs into pieces while in cold state before further processing. The processes also include the further steps of digestion in a solvent, molten salt oxidation or incineration, during which the highly reactive and hazardous spent batteries are first of all reduced to inert materials exhibiting a low chemical reactivity. Afterwards, the processes involve collecting the solid, liquid and gaseous discharges from the reactor, dissolving the solid and liquid discharges with an appropriate solvent and absorbing the gaseous effluents with an alkaline solution, mixing the resultant wash streams, separating precipitates formed from the mixed stream and neutralizing the remaining solution. Finally, the last step consists in recovering efficiently, safely, and in a relatively economical manner the valuable by-products such as vanadium and lithium compounds for reuse in the manufacture of electrochemical cells.
