Filed: 1998-09-30
Abstract: An optical channel regulator (46) is provided. The optical channel regulator (46) includes a tapped optical coupler (60) receiving an optical line carrying an optical signal. The tapped optical coupler (60) provides substantially all of the optical signal as an output. An electrically variable optical attenuator (64) receives the output of the tapped optical coupler (60) and attenuates the optical signal responsive to a feedback control signal. A  second tapped optical coupler (66) receives an output of the attenuator (64).  The second coupler (66) provides substantially all of the received optical signal as an output and provides a remaining portion of the optical signal as a tapped output. An optical detector (68) then receives the tapped output and provides an output signal representing the optical signal. A comparator (70) receives the output signal of the optical detector (68) and a reference signal. The comparator (70) compares the output signal and the reference signal and provides the feedback control signal to the attenuator (64) responsive to the comparison. As part of a multi-channel communication system, the regulator is used to adjust the levels of each channel for automatically maintaining channel balance and equalization.

Title: Combusting a hydrocarbon gas to produce a reformed gas
Inventor: WAYCUILIS JOHN J
IPC: C07C1/04
Filed: 1997-11-12
Abstract: A system and process are provided for converting a hydrocarbon gas to a reformed gas containing hydrogen and carbon monoxide. In accordance with a first embodiment, the system includes a primary combustor, compressor and power turbine. The process is practiced by compressing a feed air in the primary compressor to produce a primary air. The primary air is fed with a primary hydrocarbon gas to the primary combustor, producing a reformed gas that drives the primary power turbine. The primary power turbine is linked to the primary compressor, compressing the feed air in an energy self-sufficient manner. In a second embodiment, the system of the first embodiment further includes a secondary combustor, compressor and power turbine. The process is practiced in the same manner as the first embodiment, producing the reformed gas and driving the primary power turbine and compressor. A portion of the primary air is also fed with a secondary hydrocarbon gas to the secondary combustor, producing an off-gas that drives the secondary power turbine and compressor to compress a gas in an energy self-sufficient manner. In a third embodiment, the system is substantially the same as the second embodiment, but reconfigures the compressors and power turbines and further includes an auxiliary secondary power turbine. The process is practiced in the same manner as the first embodiment, producing the reformed gas and driving the primary power turbine and compressor. The off-gas is produced in the same manner as the second embodiment to drive the secondary power turbine, but the secondary power turbine drives an auxiliary primary compressor, compressing the feed air ahead of the primary compressor in an energy self-sufficient manner. The off-gas further drives the auxiliary secondary power turbine to provide additional power for alternate power users.

Patent CA-2285505-A1 (CA)
Inventor: MORIN AURELE
IPC: D06F53/02
Filed: 1999-10-06
Abstract: The present separator comprises an elongated body having opposed open upper and lower channels connected by a vertical web. A roller is rotatably mounted within the upper channel. The lower channel acts as a hook. Typically, the separator is adapted to be mounted to a clothes line and, more particularly, to the upper and lower runs thereof such as to prevent sagging of the lower run when clothes hang therefrom. When installed, the roller rests atop the upper run, whereas the lower run lies at the bottom of the lower channel. The weight of the clothes increases the pressure of the roller on the upper run and of the lower run on the bottom of the lower channel, whereby when the lower run is displaced, the separator will roll along the upper run in view of its roller with the separator following the displacement of the lower run in view of the frictional engagement of the lower run with the lower channel of the separator. If the distance between the roller and the bottom of the lower channel is reduced enough, the separator S will follow the lower run even when no clothes hang from the lower run.

Title: Separator for fuel cell and a method for producing the separator
Inventor: MIZUNO SEIJI
IPC: H01M8/02
Filed: 1999-12-10
Abstract: A separator for an electrochemical fuel cell provides a path for a fuel gas or an oxidative gas to an electrode and functions as a wall of a unit cell of the electrochemical fuel cell. The separator comprises a conductive metal plate, a conductive coating membrane, and a tight coating membrane. The conductive coating membrane coats the conductive metal plate where the separator contacts the electrode. The tight coating membrane coats the conductive metal plate where the conductive coating membrane does not coat the conductive metal plate. A conductivity of the conductive coating membrane is higher than the tight coating membrane, and the tight coating membrane has a tighter adhesion to the conductive metal plate than the conductive coating membrane. The conductive coating membrane comprises carbon, a precious metal, or an alloy of nickel and chromium. The tight coating membrane comprises a close-grained resin. In the electrochemical fuel cell including the separator, the electric resistance between the separator and the electrode can be restrained low, and a rust problem caused by coming-off of the conductive coating membrane from the conductive metal plate can be avoided with high reliability.
