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 t o the primary compressor, compressing the feed air in an energy self-sufficien t 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, b ut reconfigures the compressors and power turbines and further includes an auxiliary secondary power turbine. The process is practiced in the same mann er 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 secondar y power turbine drives an auxiliary primary compressor, compressing the feed a ir ahead of the primary compressor in an energy self-sufficient manner. The off - gas further drives the auxiliary secondary power turbine to provide addition al power for alternate power users.

Title: Method of authenticating information, disk playback apparatus, and entertainment apparatus
Inventor: NODA SHINJI
IPC: A63F13/73
Filed: 1999-09-22
Granted: 2005-06-07
Abstract: A playback instructing unit in a disk playback controller has a function to instruct a CPU to play back an optical disk at different access positions in an absolute authentication process and an arbitrary authentication process. An absolute decision unit has a function to be activated by an absolute authentication instruction from the playback instructing unit and authenticate the decided result from an authentication decision means according to a first rule (which declares normal authentication based on a normal decision). An arbitrary decision unit has a function to be activated by an arbitrary authentication instruction from the playback instructing unit and authenticate the decided result from the authentication decision unit according to a second rule (which declares normal authentication based on an abnormal decision). Even if a special device which can normally authenticate an optical disk that should not be authenticated normally is connected to a disk access mechanism, the optical disk that should not be authenticated normally or the special device can reliably be detected to forcibly interrupt any process being carried out, so that the optical disk can effectively be prevented from being illegally copied.

Patent CA-2286535-C (CA)
Inventor: WALL GEORGE B
IPC: B60D1/62
Filed: 1999-10-14
Granted: 2008-12-16
Abstract: The invention provides for the management and protection of excess lengths of utility cables in extendable semi-trailers. Utility cables are affixed to the front and rear sections of an extendable semi-trailer and are threaded through a protective carrier that can bend in only one direction. This directionally restrained carrier rests within a channel that shields the carrier and the cables from wear and tear and which constrains the bending of the carrier to one trans-channel turn. As the trailer is extended, the front and rear sections of the trailer and therefore the ends of the cables and carrier will move relative to one another. The cables and carrier move within the channel from a generally "U"-shaped pattern to a generally "J"-shaped pattern as the trailer moves from the retracted to the extended position.

Title: Benzene conversion in an improved gasoline upgrading process
Inventor: BORGHARD WILLIAM STERN
IPC: C10G69/04
Filed: 1998-05-12
Granted: 2008-07-22
Abstract: Low sulfur gasoline is produced from an olefinic, cracked, sulfur-containing naphtha by treatment over an acidic catalyst, preferably an intermediate por e size zeolite such as ZSM-5 to crack low octane paraffins and olefins under mild conditions with limited aromatization of olefins and naphthenes. A benzene-rich co-feed is co-processed with the naphtha to reduce the benzene levels in teh co-feed by alkylation. This initial processing step is followe d by hydrodesulfurization over a hydrotreating catalyst such as CoMo on alumin a. In addition to reducing benzene levels in the combined feeds, the initial treatment over the acidic catalyst removes the olefins which would otherwise be saturated in the hydrodesulfurization, consuming hydrogen and lowering product octane, and converts them to compounds which make a positive contribution to octave. Overall liquid yield is high, typically at least 90 % or higher. Product aromatics are typically increased by no more than 25 wt.% relative to the combined feeds and may be lower than the feed.

Title: Electronic ballast with frequency management
Inventor: BEZDON RONALD J
IPC: H05B41/392
Filed: 1999-07-20
Granted: 2005-01-25
Abstract: A microprocessor controlled, electronic ballast operates a lamp at nominal settings and shifts the operation of the ballast away from nominal settings to reduce interference. The shift is randomized by a test - flip - [shift] routine that prevents all ballasts from attempting the same correction at the same time. On DC input voltage, the frequency of the boost controller (21) is varied to reduce EMI. The ballast operates in bands (91, 92, 93) according to the input voltage. Some bands correspond to full brightness, some to a fixed amount of dimming and some to a variable amount of dimming. In the event of an abrupt change i n load, the microprocessor (31) changes the frequency of the inverter, thereby reducing output power and gradually unloading the boos t circuit and maintaining power to the microprocessor.
