Title: Frequency regulation of an oscillator for use in mwd
Inventor: COLLETTE HERMAN D
IPC: G01V11/00
Filed: 2003-12-09
Granted: 2008-09-23
Abstract: An oscillating valve driven by the pressure in a mud pulser develops a pressure variation in the mud pulse signal that is at a frequency that is different than the frequencies of the mud system. The oscillating valve is coupled to or integral with the pulse drive cylinder, whether the drive means for operation of the pulser is upstream or downstream from the orifice, or whether or not the drive means and the poppet are on the same side or opposite sides of the orifice. The oscillating valve is a bistable valve which preferably forms one wall of the drive piston of the pulser. Pressure from the drive cylinder behind the drive piston is directed in such a way as to unseat the bistable valve. When the bistable valve unseats, pressure is bled from within the drive cylinder, which also bleeds the pressure that unseated the bistable valve in the first place. When pressure drops, the bistable valve reseats, and the cycle repeats as long as pressure is being ported to the cylinder, thereby creating a tone in the drilling mud.

Title: Cyclosporine analogue mixtures and their use as immunomodulating agents
Inventor: NAICKER SELVARAJ
IPC: A61P3/10
Filed: 2002-10-17
Granted: 2014-05-27
Abstract: The invention is directed to isomeric mixtures of cyclosporine analogues that are structurally similar to cyclosporine A. The mixtures possess enhanced efficacy over naturally occurring and other presently known cyclosporines and cyclosporine derivatives. Embodiments of the present invention are directed toward cis and trans-isomers of cyclosporin A analogs referred to as ISA TX247, and derivatives thereof. Mixtures of ISA TX247 isomers exhibit a combination of enhanced potency and reduced toxicity over the naturally occurring and presently known cyclosporins. ISA TX247 isomers and alkylated, arylated, and deuterated derivatives are synthesized by stereoselective pathways where the particular conditions of a reaction determine the degree of stereoselectivity. Stereoselective pathways may utilize a Wittig reaction, or an organometallic reagent comprising inorganic elements such as boron, silicon, titanium, and lithium. The ratio of isomers in a mixture may range from about 65 to 90 percent by weight of the (E)-isomer to about 35 to 10 percent by weight of the (Z)-isomer, based on the total weight of the mixture.
Patent CA-2462466-C (CA)
Inventor: JABUSCH KIRBY
IPC: E21B47/04
Filed: 2004-03-30
Granted: 2011-05-03
Abstract: A device for determining a location of an interface between a first fluid and second fluid includes a non-mechanical sensor that measures a selected parameter of interest relating to the fluid surrounding the sensor ("the surrounding fluid") and a processor for processing the sensor measurements. The non-mechanical sensor measures a parameter relating to the surround fluid without physically co-acting with the surrounding fluid. Exemplary parameters such as thermal properties, electrical properties, fluid properties, and magnetic properties can be measured. The processor is programmed to process the sensor measurements to identify one or more characteristics in the measurements that can indicate the nature of the fluid being measured and thereby determine the location of the interface. The determined location can be used to operate a downhole device such as a pump, to provide real-time monitoring of well conditions, to record data for long-term reservoir characterization, or to actuate an alarm.

A plurality of taps is formed on a side of the coil that is not flanked by one of the L-cores. The taps are formed by extending individual windings further from the T-core than other common windings. Preferably, a hole is formed through the rectangular wire at the taps to provide a secure electrical connection to the wire.

Title: Automatic energy management and energy consumption reduction, especially in commercial and multi-building systems
Inventor: BRICKFIELD PETER J
IPC: H02J13/00
Filed: 2003-03-07
Granted: 2013-08-27
Abstract: Automatic energy management is provided, in even the most complex multi-building system. The necessity of a human operator for managing energy in a complex, multi-building system is reduced and even eliminated. Computer-based monitoring and computer-based recognition of adverse energy events,(such as the approach of a new energy peak) is highly advantageous in energy management. Immediate automatic querying of energy users within a system of buildings for energy curtailment possibilities is provided. Such immediate, automatic querying may be answered by the energy users through artificial intelligence and/or neural network technology provided to or programmed into the energy users, and the queried energy users may respond in real-time. Those real-time computerized responses with energy curtailment possibilities may be received automatically by a data processing facility, and processed in real-time. Advantageously, the responses from queried energy users with energy curtailment possibilities may be automatically processed into a round-robin curtailment rotation which may be implemented by a computer-based control system. Thus, impact on occupants is minimized, and energy use and energy cost may be beneficially reduced in an intelligent, real~time manner. The invention also provides for early-recognition of impending adverse energy events, optimal response to a particular energy situation, real-time analysis of energy-related data, etc.
