Patent CA-2287458-C (CA)
Title: Hydrocarbon synthesis with cryogenic nitrogen removal upstream of the syngas generation
Inventor: COULALOGLOU CONSTANTINE A
IPC: F25J3/02
Filed: 1998-05-05
Granted: 2005-01-11
Abstract: In a hydrocarbon synthesis process, nitrogen is cryogenically removed from natural gas to produce a synthesis gas feed comprising methane which is substantially free of nitrogen. This feed is converted to a synthesis gas comprising a mixture of H2 and CO which is substantially free of the HCN and NH3 hydrocarbon synthesis catalyst deactivating nitrogen species. This reduces the need for rejuvenating the hydrocarbon synthesis catalyst. During the cryogenic separation, C2+ hydrocarbons are separated from the natural gas and all or a portion of the separated C2-C4 hydrocarbons are added to the methane feed before it is converted into syngas, to increase syngas production. All or a portion of the separated C2-C3 hydrocarbons may be removed as LP G.

Abstract: A two-stage venting on-board refueling vapor recovery (ORVR) valve for controlling fuel tank venting to a storage canister during tank filling. A float actuated poppet has a small second stage venting hole therethrough. The poppet is mounted for relative movement with respect to a second stage vent valve member disposed on the float. During tank filling, venting is through a first stage relatively large flow area passage until rising fuel level causes the poppet to close the first stage vent flow area. Venting during continued filling is through the second stage venting hole in the poppet. After first stage valve closure relative movement or lost motion occurs between the first and second stage valve members. The poppet has an integrally molded annular resiliently flexible seal thereon which has a first stage annular sealing surface formed on one side of the poppet for sealing the first stage flow area, and a second stage annular sealing surface about the poppet hole on the opposite side of the poppet for sealing the second stage vent flow area and closing the vent passage.

Abstract: In a communication system where a continuous reverse channel transmission is utilized by redundant transmission of Walsh codes, a current transmission rate is modulated onto Walsh code polarity. In particular, a remote unit operating at a particular transmission rate utilizing a continuous reverse channel transmission modulates the transmission rate by setting the polarity of each Walsh code depending upon the current or future data traffic channel rate. In communication systems where a Reference Coherent (RC) type transmission is utilized, the particular transmission rate is modulated onto the reference symbols (501-517) by setting the reference symbols (501-517) equal to a binary "1" or "0".

Title: Synchronisation d'une station mobile dans un systeme de communications a spectre disperse
Inventor: GUSTAFSSON MARIA
IPC: H04W56/00
Filed: 1998-06-12
Granted: 2009-02-03
Abstract: Chaque trame d'une transmission par voie pilote dans un système de communications à spectre dispersé est divisée en une pluralité de créneaux de synchronisation. Chaque créneau de synchronisation comporte un code pilote. Au moins un des créneaux de synchronisation comporte en plus un code de synchronisation de gestion de trame. Pour extraire des informations de synchronisation de trame et de créneau de l'émission par voie pilote, la synchronisation du code pilote est d'abord identifiée par application d'un filtre adapté ou par corrélation avec un signal pilote reçu, par identification des crêtes et par utilisation de ces crêtes pour trouver une référence de synchronisation caractéristique des limites du créneau de synchronisation. Ensuite, l'ensemble des codes de synchronisation de gestion de trame connus est mis en corrélation avec le signal reçu par les créneaux de synchronisation inclus trouvés. Dès que l'on connaît la position dans la trame des codes de synchronisation de gestion de trame connus, il suffit de trouver une concordance corrélative dans un emplacement de créneau précis pour connaître également les limites de la trame (p.ex. la synchronisation de trame) par rapport à la position du créneau.

Abstract: A method for detecting the location of an edge, interface, seam or other structure of a workpiece uses one or two electromagnetic acoustic transducers (EMATs) to transmit an ultrasonic wave along the workpiece toward the edge and to receive a reflected wave. The velocity of the wave in the material is used in conjunction with the round trip time-of flight (TOF) of the transmitted and reflected wave, to calculate the location of the edge. This is done by placing the transducer or transducers at known locations on the workpiece. A surface wave or 90 degree shear wave can be utilized and no contact is needed between the transducer and the surface of the workpiece. Rough and/or dirty surfaces and hostile environments can be accommodated while practicing the invention.

Title: Radio location system including transceiver tags
Inventor: BELCHER DONALD K
IPC: G01S5/02
Filed: 1999-01-28
Granted: 2005-05-03
Abstract: An asset management radio location system uses time-of-arrival differentiation for random and repetitive spread spectrum, short d oration pulse "blinks" from object attached tags, to provide a practical, continuous identification of the location of each and every object within an environment of interest, irrespective whether the object is stationary or moving. Correlation-based RF processors (24) determine which signals received by tag transmission readers (10) are first-to-arrive signals as transmitted from any blinking tag, and an object location processor carries out time-of-arrival differentiation of these first to-arrive transmissions from any blinking tag to determine where the respective object is located within the environment. A low power interrogation wand may be employed to refine the location of an object by a user programmed transmission - response exchange between the wand and the tag associated with the object of interest.

Title: Sulfur-in-oil in asphalt and polymer composition and process
Inventor: HAYNER ROGER E
IPC: C09D195/00
Filed: 2000-11-28
Granted: 2008-06-10
Abstract: A sulfur in oil in asphalt and polymer blend is disclosed. An asphalt and polymer blend is first prepared and then a slurry of solid sulfur in liquid oil added. Addition of a slurry of solid sulfur in oil permits rapid and effective dispersion of the sulfur component in the asphalt/polymer blend. Uneven mixing, which can occur when sulfur is separately added as a solid to the asphalt blend, is avoided. Polymer use is optimized because polymer swelling can be completed before cross-linking occurs. The method is safer because formation of explosive clouds of sulfur dust is avoided.
