Publication number: 20070186874Abstract: Contrasted to the prior art, the present invention presents a path for the cycle steam having the fewest possible changes in direction to minimize parasite pressure losses. This invention accommodates proportioning the flow areas of the moisture separator-reheater(s) assembly to optimize performance of extracting the maximum energy from the cycle steam and in view of the economics of first cost and operating cost. The reheater tubes are straight, not U-tubed, and sloped towards the reheat steam condensate discharge. It utilizes an internal baffle in the reheating steam manifold, features which would mitigate tube binding, steam distribution to the tube bundles, flow oscillations, etc. which are expensive and difficult to alleviate.Type: ApplicationFiled: February 16, 2006Publication date: August 16, 2007Inventor: Hrant Yousoufian

Publication number: 20070186892Abstract: A method of controlling an intake air passage of an internal combustion engine is provided. The intake air passage cyclically communicates to a combustion chamber of the internal combustion engine, thereby inducting fresh air into said combustion chamber. The cyclic communication of the intake air passage to the combustion chamber generates a pressure wave in the intake air passage. The method comprises reducing an effective length of a transmission path of the pressure wave in an upstream direction of the intake air passage as a desired air flow to the combustion chamber decreases. In accordance with the method, the effective length of the pressure wave transmission path is reduced as desired air flow decreases. With the reduced effective length, the pressure wave bounces back and forth between ends of the transmission path more often before the next cyclic communication. The more bouncing attenuates the pressure wave at the next cyclic communication.Type: ApplicationFiled: February 13, 2007Publication date: August 16, 2007Applicant: Mazda Motor CorporationInventors: Shinji Kishi, Shinichi Sugihara, Masashi Marubara, Toshihide Yamamoto

The transfer path can, for instance, be a tube, a flexible hose, or another transfer mechanism. Compressed gas from the transfer path can be supplied to a solenoid valve. The solenoid valve can transfer compressed gas to the bolt piston to operate the bolt during operation of the paintball gun.Type: ApplicationFiled: April 20, 2007Publication date: August 16, 2007Applicant: SMART PARTS, INC.Inventor: Danial Jones

Publication number: 20070186917Abstract: A method for slicing an ingot may improve nanotopography at a surface of a wafer. In the method, an ingot is sliced into a plurality of wafers via a slurry while slurry is supplied to a moving wire. A first wire to form a first slicing portion at the wafer firstly slices one side of the ingot. A second wire secondly slices the remaining portion of the ingot to form a second slicing portion continued from the first slicing portion, wherein the first wire has a smaller diameter than that of the second wire.Type: ApplicationFiled: April 12, 2007Publication date: August 16, 2007Inventors: Eunsang Ji, Kyungmoo Lee

Publication number: 20070186920Abstract: A pellet stove utilizing gravity feed and natural draft more effectively and efficiently burns pellet fuel while producing less air pollution and ash. In one embodiment, the pellet stove has a primary combustion area comprising a burn unit removably disposed in the vent tube, a feed tube defining a fuel chamber above the burn unit and a secondary combustion area, comprising a burn box defining a secondary burn chamber, below the burn unit. The burn unit has a removable receptacle which defines a primary burn chamber that receives pellet fuel from the fuel chamber and discharges substantially burned fuel to the secondary burn chamber for additional burning. Openings in the burn box, pellet receptacle and vent tube draw air into the burn chambers. A control mechanism controls the air flow to regulate the heat generated by the pellet stove. The pellet stove can be manufactured in various aesthetically pleasing designs.Type: ApplicationFiled: February 15, 2006Publication date: August 16, 2007Inventor: Gary Wisener

Publication number: 20070186921Abstract: A system is disclosed to employ optical collectors 10 including cylindrical troughs 14 below ground level for solar-thermal generation of electricity. In one preferred embodiment, the interior wall 24 of the cylindrical trough 14 is coated with reflective material to act as primary cylindrical collector mirror 20. Since the trough 14 is situated in the ground, this mirror 20 can be very large and large concentrated power densities can be obtained. A set of corrector mirrors 28 in a relative small boxlike structure 22 focus all rays on a receiver tube 16 situated at the center of curvature of the trough 14. The tracking of the sun is achieved by rotating this collector box 22 in the trough 14 about the center of curvature. No movement of large mirrors is required since the large primary mirror 20 is fixed and the corrector mirrors 28 in the corrector box 22 are relatively small. The collector 10 can also be used as concentrator for photovoltaic cells or it can be used for water heating.Type: ApplicationFiled: February 2, 2006Publication date: August 16, 2007Inventor: Ryno Swanepoel

Publication number: 20070186922Abstract: A panel for generating electrical and thermal power comprises an upper layer formed by a translucent sheet having an array of photovoltaic cells and a support structure including a pair of multi-walled translucent sheets, and an underlying reflective sheet. The multi-walled translucent sheets each include a number of elongated channels, with the two sheets being arranged so that their channels lie perpendicular to one another for rigidity. The channels within at least one of the sheets are filled with circulating water, which is heated by solar energy not absorbed within the photovoltaic cells.Type: ApplicationFiled: January 27, 2006Publication date: August 16, 2007Inventor: Schaefer Guenter
