The tank (10) has a sealable opening (18) suitable for removal or insertion of the gas emitting entities (20) and the gas emitting entities (20) have a respective gas release device, which is operable as a response on a stimulation signal. A volume (14) surrounding the gas emitting entities (20) inside the tank (10) is the sole fluid connection between an opening of the gas release device and the tank gas outlet (28). Methods for storing and releasing gas are also presented.Type: ApplicationFiled: September 14, 2006Publication date: November 20, 2008Applicant: MANBAS ALPHA ABInventor: Lars Stenmark

Patent number: 7412956Abstract: A cylinder barrel (1) for housing a piston comprises a sheet metal liner (2) and a reinforcing structure (10) located outside the sheet metal liner (2). The reinforcing structure (10) comprises a glass-fiber-reinforcing layer (12) and a carbon-fiber-reinforcing layer (13). The glass-fiber-reinforcing layer (12) comprises a plain cloth (20) made of glass fiber covering the sheet metal liner (2). The carbon-fiber-reinforcing layer (13) comprises a carbon fiber string (31) wound around the outer circumference of the glass-fiber-reinforcing layer (12) along a spiral path. According to the this construction, the reinforcing structure (10) has a high flexibility which is required for preventing cracks in the reinforcing structure (10) while maintaining a high rigidity of the entire cylinder barrel (1).Type: GrantFiled: April 26, 2006Date of Patent: August 19, 2008Assignee: Kayaba Industry Co., Ltd.Inventors: Mitsunori Gotou, Tadashi Hiraga

Publication number: 20080173651Abstract: This invention relates to the field of gas-containing storage vessels, and more specifically to the provision for antimicrobial surfaces within such vessels and in the connecting hardware associated with various applications of such vessels, so that microbial colonization of the interior of such vessels may be eliminated or retarded. This antimicrobial feature may result in improved safety in the use of such vessels, with reduced risk of the transmission of infection to a user. The invention further includes methods to provide gas-containing storage vessels with antimicrobial surfaces, so that microbial colonization of the interior of such vessels may be eliminated or retarded.Type: ApplicationFiled: June 17, 2005Publication date: July 24, 2008Inventor: Jeffrey H.

Publication number: 20080156813Abstract: A container for transporting and storing hazardous materials such as Chlorine includes a cylindrical body having end caps. The end caps are welded to the body to form a pressure vessel. The end caps have a peripheral edge that is recessed with respect to the ends of the body to protect the weld against damage from impact. The configuration of the juxtaposed components forms a lap joint that can be affixed together by a fillet weld.Type: ApplicationFiled: May 8, 2007Publication date: July 3, 2008Inventors: Alan G. Eckert, Trevor M. Rummel

Publication number: 20080115744Abstract: A hydrogen fuel system for an internal combustion engine includes an electrolyzer for generating hydrogen and oxygen gases. The engine exhaust may be recycled through the electrolyzer where it is converted to hydrogen and oxygen. A water reservoir in fluid communication with the electrolyzer maintains the water level in the electrolyzer. The hydrogen and oxygen generated by the electrolyzer may be routed to the internal combustion engine and provide the fuel for the engine. Hydrogen and oxygen not consumed by operation of the engine is stored in separate pressurized storage tanks. Expanders lower the pressure of pressurized hydrogen and oxygen for use to power the engine and provide electric power to the electrolyzer.Type: ApplicationFiled: September 24, 2007Publication date: May 22, 2008Inventors: STEPHEN M. FLESSNER, Eric S. Flessner

Publication number: 20080041291Abstract: A deep ocean gas storage system for storing compressed gas, the system comprising an inflexible thin walled storage vessel anchored to the sea floor having an axis located in water substantially perpendicular to and on a sea floor below sea level, a gas intake for admitting and discharging compressed natural gas to and from the vessel; a water port for admitting and discharging water to the vessel using hydrostatic pressure to discharge compressed gas from the vessel at a substantially constant discharge pressure as the volume of the gas in the storage vessel decreases when water content of the vessel increases; a conduit fluidly connected with the water port oriented substantially parallel to the axis having a discharge opening above the level of sea water in the vessel; and a valve disposed at the gas intake to the vessel for controlling compressed gas admission and discharge.Type: ApplicationFiled: August 19, 2006Publication date: February 21, 2008Inventors: Edward E. Horton, James V. Maher

Patent number: RE41142Abstract: A pressure vessel for holding a pressurized fluid such as compressed natural gas (“CNG”) includes two end cells and zero or more interior cells. The cell geometry ensures that the cells meet one another at tangential circular surfaces, thereby reducing the tendency of adjacent cells to peel apart. A web secured about the cells includes two sheets that are tangent to the cells. Unused volumes between the cells and the web contain wedges of foam or rubber. A valve provides fluid communication between the interior of the pressure vessel and a pressurized fluid line. The filled weight of one pressure vessel does not exceed the filled weight of a conventional gasoline tank that occupies substantially the same space as the pressure vessel. The pressure vessel may be configured with exterior recesses for engaging conventional gasoline tank straps.Type: GrantFiled: March 29, 2002Date of Patent: February 23, 2010Assignee: Alliant Techsystems Inc.Inventors: Michael D.
