Patent CA-2290199-C (CA)
Title: Fuel tank vent system with orifice
Inventor: PEOTTER BENJAMIN G
IPC: B65D90/34
Filed: 1999-11-22
Granted: 2004-09-21
Abstract: A fuel tank has a void air space when the tank is filled through a filler tube that upstands from a reservoir.      The reservoir has a baffle that depends from a top wall of the reservoir. Fuel entering the reservoir from the filler tube fills the reservoir up to the level of the lowermost edge of the baffle. Further filling of the tank causes the fuel level to rise in the filler tube. However, a void space is created because air and fuel vapor are trapped in the reservoir on the opposite side of the baffle as the filler tube, which prevents overfilling by an operator. A vent system connects the void space with the top end of the filler tube. Hydrostatic pressure exerted by the fuel on the air and fuel vapor in the void space expels the air and fuel vapor through the vent system to the filler tube, causing the fuel level to rise in the void space and simultaneously to lower in the filler tube. Eventually all the air and fuel vapor are expelled, and the fuel level in the filler tube is then at a minimum level. The invention is capable of venting a fuel tank that is tilted in operation such that a void space is present in the reservoir.
Patent CA-2293772-C (CA)
Inventor: WINEBRENNER THOMAS E
IPC: B05B1/26

Granted: 2008-02-19
Abstract: A side wall sprinkler assembly includes a body, a deflector, a closure member, and a trigger assembly. The deflector is movably mounted to the body between a retracted position wherein the deflector is at least partially recessed within a cavity of the body and an extended position wherein the deflector is spaced from an outlet opening of the body for dispersing pressurized fluid which flows from the outlet opening. The trigger assembly applies a biasing force to the deflector to urge the deflector into its retracted position and to urge a seal to sealingly engage the body to thereby close the outlet opening, with the trigger assembly at least partially recessed in the cavity when applying the biasing force. Upon detecting a fire, the trigger assembly releases the biasing force whereby deflector moves to an extended position.

Title: Stent with variable wall thickness
Inventor: UMBACH JAMES E
IPC: A61F2/06
Filed: 2000-03-31
Granted: 2008-05-13
Abstract: A stent is made flexible along its length. The stent initially starts as a metal sheet. It is rolled in its central region to a specified wall thicknes s. Thereafter, the stent is photochemically etched to produce the desired cell pattern of the design of the stent. Then, the stent is folded and the metal is joined to give rise to a stent with multiple wall thickness. For instance, larger wall thicknesses at the end of the stent versus smaller wall thicknesses at its center. Various other possible manufacturing methods are useful with respect to this stent. The stent can also be produced in an initial tube shape. The tube can be etched several times to get varying wall thickness.

Abstract: L'invention concerne une seringue d'injection qui comprend un boîtier (1), une tige de piston (6) présentant une coupe transversale non circulaire et un filetage externe (7), un entraînement de la tige de piston comprenant un guide (85) de tige de piston s'accouplant à la coupe transversale de la tige de piston (6) et un écrou (4) qui ne peut pas être déplacé axialement et s'accouple au filetage (7) de la tige de piston (6) afin de former un raccord fileté d'autoblocage et un mécanisme doseur. Ce mécanisme comprend un raccord fileté d'autoblocage le long duquel un bouton d'injection est dévissé par rotation d'un élément doseur (81) afin de faire saillie à partir du boîtier (1). Ce raccord fileté transforme ce mouvement axial en rotation d'un des éléments d'entraînement (85) du piston par rapport à l'autre (4) sous l'effet de retour axial du bouton d'injection (88). Un accouplement unidirectionnel entre l'élément écrou (4) et le guide (85) de la tige de piston permet un mouvement de rotation qui transporte la tige de piston (6) dans une direction distale. L'accouplement présente une réduction initiale qu'il faut vaincre avant la rotation, ladite réduction étant suffisamment importante pour résister aux couples exercés pendant le dosage.

Title: Wireless communication system in which virtual links have a variable transmission capacity
Inventor: BAUTZ GREGOR
IPC: H04L5/16
Filed: 1998-10-23
Granted: 2007-05-22
Abstract: Communication system for transmitting data packets via a plurality of virtual wireless communication links established between a base station and a plurality of operable mobile stations, the communication links having a variable transmission capacity and wherein messages for a requirement-oriented data transmission are transmitted on a plurality of communication links or channels within three types of control data packets. Said control data packets contain messages grouped according to their importance, allowing an efficient error treatment. The partitioning of messages into groups further allows an increase of the flexibility and efficiency of a data transmission, since only necessary control information is transmitted and a direct decoding of received control data packets becomes possible without a detour via a higher level of a used communication model.

Abstract: A suspension system configured to provide suspension to a railroad maintenance machine having a frame and a chassis, where the suspension system is selectively operable between work and transportation modes of the machine. The suspension system includes a suspension that is operable between a first position and a second position.  The first position is when the suspension is substantially inflated for transportation of the machine, and the second position is when the suspension is substantially deflated for conducting railroad maintenance. At the first position, the suspension absorbs the rail bed-induced shock vibrations, and at the second, substantially deflated position, the suspension effects contact between the frame and the chassis so that the entire weight of the frame and other machine components is resting directly on the chassis to provide increased stability during railroad repair and maintenance.      Contact with the rail is maintained in either position.

Title: X-ray measurement of resin distribution in a cellulosic material
Inventor: FENG MARTIN W
IPC: G01N23/223
Filed: 2002-01-31
Granted: 2006-02-21
Abstract: A method for measuring bonding agent content and distribution in a composite product that includes bonding agent and cellulosic material. The method involves using a bonding agent that includes electronegative functional groups and an X-ray active cationic label bonded with the functional groups in the manufacture of the composite product. The cellulosic material is exposed to X-rays to generate a characteristic fluorescence signal from the label. The X-ray fluorescence of the label is measured to determine the amount and distribution of the label in the cellulosic material and thereby the amount and distribution of the bonding agent in the composite product. The present invention also provides a bonding agent composition useful for determining the distribution of the bonding agent in a composite product comprising a bonding agent containing electronegative functional groups and a label compound that includes positively charged ions to emit characteristic fluorescence when exposed to X-rays. The bonding agent and the label compound are homogeneously mixed.
