Title: Method for enabling communications dependent on user location, user-specified location, or orientation
Inventor: SOKOLA RAYMOND L
IPC: H04W4/48
Filed: 2005-03-21
Abstract: A system and method for enabling communications in a wireless communications network (10) on the basis of user-specified locations or orientations, having particular utility to vehicle-based communications. Users of the network broadcast their locations and orientations (headings) to a central server (24). Using his user interface (51), a user can specify either a location or a heading and transmit the same to the server (24). The server (24) will query other system users to determine which correspond to the specified locations or orientations, and the requesting user is then permitted to contact such other users. With such functionality, a given user can, for example, be enabled to communicate with other users at or near his current location, at or near some specified distant location, or that are traveling in the same direction as the user.

Title: Nucleic acids for apoptosis of cancer cells
Inventor: NORTH DON ADAMS
IPC: A61K48/00
Filed: 2005-12-19
Abstract: The present invention relates to cancer markers and methods of detecting cancer markers in a sample. The sample may be peripheral blood. Cancer markers are most commonly mutated or abnormal DNA sequences associated with metastatic cancer. Markers may be detected using PCR, microarrays, or other nucleic acid or peptide-based assays. These methods may be used for a variety of diagnostic purposes, including initial, early-stage or later diagnosis of cancer, particularly metastatic cancer and monitoring of cancer or treatment progression. The cancer markers may also be used to create a cancer marker profile. Treatment may be directed based on this profile. Additionally, methods using blood may provide a cancer marker profile of mutations or abnormalities found in at least one of several tumors in the body, instead of merely one tumor. The invention also include kits, such as primer kits, and microarrays for use in performing the various methods.

Abstract: La présente invention a trait à un appareil et un procédé pour former des produits coniques moulés, comme des blocs de maçonnerie, grâce auxquels des produits finis de haute qualité sont retirés de leur moule sans nécessiter une machinerie complexe de démoulage. Le moule peut comprendre une ou plusieurs cavités comportant une ou plusieurs parois de cavité mobiles. Les parois de cavité mobiles peuvent comprendre une doublure dextrémité comportant une surface de formation de produit plane capable de se déplacer dune position verticale à une position angulaire. Les produits coniques peuvent être formés en déplaçant le moule vers une palette afin que cette dernière se mette en prise avec la doublure dextrémité et en permette le déplacement dune position verticale à une position angulaire. Une matière moulable peut alors être introduite dans la cavité du moule et y demeurer jusquà ce quelle se maintienne. Le moule peut alors être éloigné de la palette de manière quun produit moulé demeure sur la palette, ce qui permet à la doublure dextrémité de se déplacer dune position angulaire à une position verticale.
Patent CA-2592933-A1 (CA)
IPC: F17D3/12
Filed: 2007-07-03
Abstract: An automatic pump control device for an injection pump used to inject fluid (typically methanol) into oil or natural gas wells to prevent freezing. The device enables the pump to operate at rates as low as one full stroke per 1.5 minutes (i.e., 0.67 stroke/min), substantially slower than current rates of approximately fifteen strokes per minute. The device comprises a main body; an extension air pilot;  a retraction air pilot; a toggle mechanism that actuates the extension air pilot to extend the pump piston, that at the end of the extension stroke actuates a retraction air pilot to retract the pump piston, and that automatically continues the two stroke cycle; a drive mechanism for driving the toggle mechanism; an overstroke mechanism to prevent over driving the retraction air pilot at the end of its stroke; an optional stroke speed adjustment valve; a circuit to circulate and transport a gas; and piston, spool, and sleeve for switching the path of the gas. The automatic pump control device operates over a wide range of flow rates and pressure ranges, thus enabling installation of the automatic pump control device to virtually all manufacturers' injection pumps.

Abstract: Method and assembly for determining the presence of soot particles in a gas stream such as in the air. To prevent the disturbing effect of salts and the like that may be deposited on soot particles, it is proposed to introduce the soot particles into water as a suspension. The salts concerned dissolve in the water and have no effect when determining the change in optical properties resulting from the presence of the soot particles. This determination comprises in particular a light transmittance measurement The presence of the soot particles can be determined after the gas stream is first passed through a filter, as a result of which a particle size distribution can be determined.  Suspension of the soot particles can be achieved by subjecting these to a stream of steam, whereby the steam condenses on the soot particles and then causes these to precipitate out of the gas. The various processes can be expedited by using a cyclone.

Patent CA-2599906-A1 (CA)

Filed: 2005-12-27
Abstract: A substantially ring-shaped seat section (8) protrudes from an inner circumference wall in a through hole (4) of a container attaching section (6) made of a metal. On an outer circumference of an electrode shaft (3) held in the through hole (4) through an insulator (5) made of a synthetic resin, locking protrusions (13, 14), which have a diameter larger than a hole diameter of the seat section (8), are provided at a distance from the seat section (8), on at least inner side or outer side of the seat section (8) in a shaft direction of the electrode shaft (3). Thus, for instance, when the inside of the metal container (2) is at a high temperature, the insulator (5) is destroyed and the electrode shaft (3) is to jump out from the container attaching section (6) to the outside or the inside of the metal container (2), the locking protrusions (13, 14) lock the seat section (8) and prevent the electrode shaft (3) from jumping out. Furthermore, since a space provided between the electrode shaft (3) and the container attaching section (6) due to the destruction of the insulator (5) is covered by having the locking protrusions (13, 14) lock the seat section (8), leakage of a liquid in the metal container (2) can be suppressed to minimum even the insulator (5) is destroyed.
