Patent CA-2475846-A1 (CA)
Title: Low-voltage electromagnetic riveter
Inventor: ARNTSON PAUL R
IPC: B21J15/24
Filed: 1997-02-03
Abstract: A low-voltage electromagnetic riveter (LVEMR) including two opposed rivet guns for upsetting rivets during the assembly of structural parts is disclosed.  Variable capacitor banks are discharged to provide a variable current pulse which flows through a driver coil and a mass-mounted coil of each rivet gun. Preferably, the mating faces of the coils are contoured to assist in the alignment of the coils. The driver coils are affixed to the ends of drivers that drive rivet dies into the ends of a rivet to be upset. The LVEMR is controlled such that the net magnetic forces generated between the two pairs of coils actuate the rivet guns so that one end of the rivet is impacted slightly before the other end. The delay is controlled by a delay generator. Further, rapid-acting ground fault detection circuits cause a power shutdown and capacitor bank discharge in the event of a ground fault.

Title: Bipolar plate having integrated gas-permeable membrane
Inventor: DEFILIPPIS MICHAEL S
IPC: H01M8/04
Filed: 2003-03-06
Abstract: The present invention is directed to a novel anode plate forming an anode chamber of a fuel cell. The anode plate includes an anode fuel flow field, a substantially gas permeable membrane, and a channel coupled to an outlet positioned immediately adjacent said membrane. The channel directs gaseous effluents produced in the anode chamber out of the fuel cell via the outlet. This novel anode plate may be used in a single fuel cell, electrically and mechanically coupled to a cathode plate in a multi-fuel cell arrangement, or combined with a cathode plate producing a bi-polar plate for a fuel cell stack. Alternatively, the features of the anode plate and cathode plate may be integrated into a single component, thus improving performance and limiting the size of a stack ad system implementing said stack.

Patent CA-2482969-A1 (CA)
Title: Dilation balloon for endoscope
Inventor: BARTHEL JAMES S
IPC: A61F2/958
Filed: 2003-04-11
Abstract: The dilation balloon of the subject invention preferably comprises a balloon portion mounted about a shaft that, when inflated, produces a configuration comprising a tapered distal end and a proximal end or butt that is substantially flat (preferably truncated) and is adapted to generally conform with the outer contours of an endoscope through which it is introduced when the balloon is pulled back against the endoscope face. The close engagement of the subject balloon catheter and endoscope, when forming a balloon-scope train, enables the scope to more readily navigate strictures and tortuous body lumen, as well as allows the balloon to act as a lens for viewing anatomical structure within the body lumen, such as tumors, strictures, and the inner luminal wall surface itself.
