Patent number: 6050085Abstract: In order to improve a method of injecting a first and a second fuel component into a combustion chamber, particularly of a rocket engine, wherein an injection element guides the first fuel component in an inner cylindrical stream and the injection element guides the second fuel component in an annular stream surrounding the inner cylindrical stream, so that by comparison with known methods improved mixing and more homogeneous preparation of the fuel takes place on injection into the combustion chamber, it is proposed that in the injection element the first and/or the second fuel component is guided by an element which produces a pressure drop and is disposed and constructed in such a way that the energy released during the pressure drop is at least partially converted into turbulence energy of the stream of the first and/or the second fuel component in order to achieve a good intermixing of the two fuel components in the mixing zone.Type: GrantFiled: December 12, 1997Date of Patent: April 18, 2000Assignee: Deutsches Zentrum fuer Luft- und Raumfahrt e.V.Inventor: Wolfgang Mayer

Patent number: 5564197Abstract: The dry end of a paper machine comprises a first dryer group with top drying cylinders, with a first drying wire and with bottom deflection suction rolls. Adjacent this, there is a second dryer group with bottom drying cylinders, with a second drying screen and with top deflection suction rolls.

Patent number: 5526579Abstract: The present invention relates to a dryer section of a machine for the production of fibrous web, such as a paper web. The dryer section comprises at least one dryer group having at least one drying cylinder and an endless porous support belt that guides the web around each cylinder. This is followed by a reversing roll being formed as a suction roll. With the web being supported by said porous support belt the web directly contacts said reversing roll. A distance of at least 150 mm is provided between the cylinder and the reversing roll. A sealing strip extends transversely over and close to the inner side of the endless porous belt in the region where web and belt are traveling off the cylinder. For deflecting the air boundary layer which arrives together with the belt, a sealing support beam also extends transversely over the inner side of the belt and supports the sealing strip.Type: GrantFiled: February 17, 1993Date of Patent: June 18, 1996Assignee: J.M.
