Patent CA-2369608-A1 (CA)
Title: Production of a gas hydrate slurry using a fluidized bed heat exchanger
Inventor: WAYCUILIS JOHN J
IPC: F17C11/00
Filed: 2000-12-26
Abstract: A multi-phase fluid stream having an initial gas phase and an intitial liquid phase is converted to a gas hydrate slurry. The initial liquid phase includes an initial water and the initial gas phase includes a hydrocarbon gas.      An inert solid particle medium is entrained in the multi-phase fluid stream to form a fluidizable mixture which is conveyed through the interior of a heat transfer tube (26) enclosed within a shell (18). A heat transfer medium resides within the shell (18), but is external to the heat transfer tube (26) in fluid isolation from the fluidizable mixture. The wall of the heat transfer tube (50) provides a heat transfer surface for heat exchange between the multi-phase fluid stream and the heat transfer medium, cooling the multi-phase fluid stream on contact to a temperature below the gas hydrate formation temperature and converting at least a portion of the hydrocarbon gas and initial water to a plurality of solid gas hydrate particles. The solid particle medium substantially prevents accumulation of the solid gas hydrate particles on the tube wall (50). The fluidizable mixture is separated from the solid particle medium to recover a gas hydrate slurry containing the plurality of solid gas hydrate particles and the remaining portion of the initial liquid phase.

Title: On-demand overlay routing for computer-based communication networks
Inventor: RICCIULLI LIVIO
IPC: H04L45/24
Filed: 2000-06-16
Abstract: Methods and apparatus are disclosed for dynamically discovering and utilizing an optimized network path through overlay routing for the transmission of data. A determination whether to use a default network path or to instead use an alternate data forwarding path through one or more overlay nodes is based on real-time measurement of costs associated with the alternative paths, in response to a user request for transmission of message data to a destination on the network. Cost metrics include delay, throughput, jitter, loss, and security. The system chooses the best path among the default forwarding path and the multiple alternate forwarding paths, and implements appropriate control actions to force data transmission along the chosen path. No modification of established network communication protocols is required.

Inventor: RAJABALI ASHRAF
IPC: F17D1/12
Filed: 2002-03-15
Abstract: A system takes low pressure (LP) liquid and transfers them into a high pressure (HP) gas pipeline using an energy transfer system. A volume of HP gas is used as the energy source for driving a lesser volume of LP liquid into a HP downstream system. Preferably, liquids separated from wellhead effluent are separated from gases and are directed to the energy transfer pump for transfer into a HP gas pipeline. Substantially dry gases from the HP pipeline are directed to the energy transfer pump for providing the drive energy for elevating the pressure of the liquids. This system eliminates the prior art blowcase vessel system and does not require onsite utilities.

Abstract: The invention allows pedestrian, vehicle or bicycle to signalize its presence on intersection by using IR(Infrared) transmitter. The signal is sent to IR  Receiver embedded into Pedestrian Push Button Box. From there signal is sent through existing wires to the traffic light control,system. Using this information the system can modify time for the green light on the same way it is modified when pedestrian pushs the button on the Push Button Box. This will improve traffic flow efficiency on any kind of intersection specially on intersection of minor and major streets where the time duration of green light on the main street is much longer than time of green light on the minor street.
