Title: Control for pipeline gas distribution system
Inventor: SCHARF PAUL F
IPC: G05D16/20
Filed: 2003-01-29
Abstract: A method of controlling a gas distribution system (1) in which one or more air separation plants (18, 20) supply gaseous oxygen and nitrogen products to pipeline sections (10, 12). The air separation plants (18, 20) are controlled by supervisory control systems (30, 32) that direct production rates of the gaseous products to be consumed by customers (14, 16) connected to the pipeline sections (10, 12). The gas distribution system (1) is controlled by a model predictive control system (34) in which empirically determined open loop response models are used to generate open loop responses of the pipeline sections (10, 12) due to changes in customer demands. Optimized closed loop responses in production rate requests to the supervisory control systems (30, 32) are generated by model predictive control techniques.

Filed: 1996-10-11
Abstract: A short cell multiplexing is provided for chiefly transmitting data shorter than the payload of a standard ATM cell (basically the data of less than 48 bytes, but the data more than 48 bytes can be allowed). A standard ATM cell assembler 1 converts various forms of input information into short cells, places the short cells in standard ATM cells efficiently considering their information length, and output them to a B/ISDN network 7. The standard ATM cell disassembler 2 disassembles the standard ATM cells, which are assembled by the standard ATM cell assembler 1 and is input through the B-ISDN network 7, into short cells, converts the short cells into those with the original input information forms, and outputs them to channels.      The configuration makes it possible for the short cell ATM cell multiplexing to improve channel efficiency with small delay, and matching to the standard ATM system.

IPC: E21B19/00
Filed: 2005-04-29
Abstract: The present invention is a cable drawworks for a drilling rig having a three--phase AC electric motor controlled by a variable frequency drive control system. A primary drive transmission consisting of a chain and sprockets connects the motor to a drum shaft that passes through the hub of a cable drum. The drum shaft is rotatably mounted on the drawworks frame whereas the cable drum is rotatably mounted on the drum shaft. The drum shaft connects to a secondary drive transmission that connects the drum shaft to the cable drum. The secondary drive transmission consists of a planetary gear transmission set where the ring gear is fixed to the drawworks frame, the planetary gear sub-assembly is attached to the cable drum and the sun gear is affixed to the drum shaft. Each end of the cable drum has a brake drum and a brake band wrapped around thereon. A brake actuating system is used to tighten the bands around each drum during braking conditions and includes an equalization linkage system between the brake bands resulting in equal braking forces being applied to each brake drum. The present invention results in a simplified cable drawworks system that is compact enough to be mounted on the drilling rig floor and that eliminates the need for liquid cooling of the braking mechanism.
