20090260622 | SOLAR STEAM GENERATOR HAVING A STANDBY HEAT SUPPLY SYSTEM - A standby heat supply system is provided for a solar receiver steam generator to maintain the system at a relatively constant temperature during the nocturnal period when solar radiation is unavailable. An exemplary solar steam generator having a standby heat supply system includes a steam loop having at least one solar panel, a steam drum and circulating pump, whereby solar energy heats the water to generate steam which is provided to the steam drum. The standby heat supply system includes an external standby heater wherein the water from the steam drum is provided to the external standby heater. A heat isolation valve is actuated during the nocturnal period to allow the water to circulate through the standby heater. Another exemplary embodiment of a solar steam generator includes an internal standby heat supply system having heater elements immersed in the steam drum for direct heating of the water during nocturnal periods. | 10-22-2009 |
20090261591 | SOLAR STEAM GENERATOR - A solar power generation system includes a solar receiver disposed on a tower that receives radiant heat reflected from a field of solar collectors. The solar receiver includes an evaporator having a plurality of vertically oriented tubes to form a panel for receiving a fluid, such as water and/or steam, wherein the tubes have a rifled internal surface. The fluid within the tubes has a mass flow greater than 0.2×10 | 10-22-2009 |
20090277443 | CONTINUOUS MOVING BED SOLAR STEAM GENERATION SYSTEM - A continuous moving bed solar steam generation and storage system is provided to generate steam for production processes after loss or reduction of received solar energy. The system includes a receiver | 11-12-2009 |
20100242815 | SEALPOT AND METHOD FOR CONTROLLING A SOLIDS FLOW RATE THERETHROUGH - A sealpot for a combustion power plant includes a downcomer standpipe which receives solids of the combustion power plant, a bed including a first end and a second opposite end, the first end connected to the downcomer standpipe, a discharge standpipe disposed at the second opposite end of the bed, and an orifice plate disposed between the bed and the discharge standpipe separating the discharge standpipe from the bed. The orifice plate includes apertures disposed at a height above the bed which allow transport of fluidized solids and gas through the orifice plate. | 09-30-2010 |
20120111243 | CONTROL VALVE AND CONTROL VALVE SYSTEM FOR CONTROLLING SOLIDS FLOW, METHODS OF MANUFACTURE THEREOF AND ARTICLES COMPRISING THE SAME - Disclosed herein is a solids flow control valve comprising a standpipe; a shoe; and a transport pipe; wherein the standpipe is in operative communication with the shoe and lies upstream of the shoe; the standpipe comprising a first end and a second end, where the first end is in contact with a source that contains disposable solids and the second end is in fluid contact with the shoe; the shoe being operative to restrict the flow of the disposable solids; the transport pipe being disposed downstream of the shoe to receive and transport the solids from the shoe. | 05-10-2012 |
20120111535 | ORIFICE PLATE FOR CONTROLLING SOLIDS FLOW, METHODS OF USE THEREOF AND ARTICLES COMPRISING THE SAME - Disclosed herein is an orifice plate comprising one or more plates having orifices disposed therein; the orifices being operative to permit the flow of solids from a moving bed heat exchanger to a solids flow control system; where the orifice plate is downstream of a tube bundle of the moving bed heat exchanger and upstream of the solids flow control system and wherein the orifice plate is operative to evenly distribute the flow of solids in the solids flow control system. | 05-10-2012 |

20120176859 | MARINE SEISMIC STREAMERS - The subject disclosure relates to seismic streamers. More specifically, the subject disclosure relates to seismic streamers with self healing properties. | 07-12-2012 |
20130028050 | DETERMINING AN ORIENTATION ANGLE OF A SURVEY SENSOR - Measurement data acquired by at least one sensor in a cable structure towed through a body of water is received. A torsional vibration noise component in the measurement data is estimated. The torsional vibration noise component is used to estimate a rotation angle of the at least one survey sensor with respect to a reference coordinate system of the cable structure. | 01-31-2013 |

20130343155 | SYSTEM AND TECHNIQUE TO SUPPRESS THE ACQUISITION OF TORQUE NOISE ON A MULTI-COMPONENT STREAMER - A technique includes distributing particle motion sensors along the length of a seismic streamer. Each particle motion sensor is eccentrically disposed at an associated angle about an axis of the seismic streamer with respect to a reference line that is common to the associated angles. The sensors are mounted to suppress torque noise in measurements that are acquired by the particle motion sensors. This mounting includes substantially varying the associated angles. | 12-26-2013 |
20130343157 | Neutrally-Buoyant Borehole Investigation Tools and Methods - The disclosure provides neutrally-buoyant tools for seismic data collection. The tools may range from several hundred meters to several kilometers in length and have integrated sensors which move along with the borehole fluid in response to a passing seismic wave. The disclosure also provides methods of deploying neutrally-buoyant tools, which includes using a tractor, adding a weight or both to the tool in order to overcome the difficulty of lowering a neutrally buoyant tool into a borehole, and optionally occasionally clamping the tool to the borehole to alleviate tension in the tool. This disclosure also provides methods of acquiring seismic data, which involves positioning a neutrally-buoyant tool in a borehole such that the tool is able to move relatively freely along with the borehole fluid in response to a seismic wave passing through the fluid, firing a seismic source, and using the sensors to collect seismic data generated thereby. | 12-26-2013 |
