Publication number: 20080251128Abstract: In an air mixing arrangement wherein a primary fluid is introduced through an opening in a wall to be mixed with a secondary fluid flowing along the wall surface, the opening is airfoil shaped with its leading edge being orientated at an attack angle with respect to the secondary fluid flow stream so as to thereby enhance the penetration and dispersion of the primary fluid stream into the secondary fluid stream. The airfoil shaped opening is selectively positioned such that its angle of attack provides the desired lift to optimize the mixing of the two streams for the particular application. In one embodiment, a collar is provided around the opening to prevent the secondary fluid from contacting the surface of the wall during certain conditions of operation. Multiple openings maybe used such as the combination of a larger airfoil shaped opening with a smaller airfoil shaped opened positioned downstream thereof, or a round shaped opening placed upstream of an airfoil shaped opening.Type: ApplicationFiled: June 20, 2008Publication date: October 16, 2008Applicant: United Technologies CorporationInventors: Fabio R. Bertolotti, David S. Liscinsky, Vincent C. Nardone, Michael K. Sahm, Bernd R. Noack, Daniel R. Sabatino

Publication number: 20080060518Abstract: An emission treatment system includes a first separation device that is operable to introduce one or more sorbents into an exhaust stream having emission products. The sorbent captures the emission products such that the exhaust stream includes sorbent with captured emission products. A second separation device located downstream from the first separation device receives the exhaust stream and utilizes an electrostatic potential to separate the sorbent with captured emission products from the exhaust stream into a discharge stream to produce a clean stream.Type: ApplicationFiled: September 8, 2006Publication date: March 13, 2008Inventors: Sergei F.

Patent number: 6170308Abstract: The rate of impact between the peening elements and an internal surface of a hollow part is a function of the vibration frequency, and there is a cut-off frequency at which a hollow part can vibrate and induce repeated impact between its internal surface and the peening elements because the rate of impact becomes erratic and loses its cyclical nature as the vibration frequency deviates from the cut-off frequency. The present invention provides a method for determining the cut-off frequency at which a hollow part can vibrate and maintain the repetitive nature of the impact between its internal surface and the peening elements. Such a method requires a peening element speed limit ratio, which is the ratio of the velocity of the hollow part compared to the velocity of the peening element above which the rate of impact begins to become erratic and lose its cyclical nature.Type: GrantFiled: July 20, 1999Date of Patent: January 9, 2001Assignee: United Technologies CorporationInventors: William A. Veronesi, Pedro Sainz de Baranda, Vincent C. Nardone, Stephen E. Tolman, Paul H. Wawrzonek

Patent number: 5950470Abstract: The present invention is a method and apparatus for peening the internal surface of non-ferromagnetic hollow parts. Ferromagnetic peening elements are inserted into the non-ferromagnetic hollow part, and a magnetic dipole creates a magnetic field through the non-ferromagnetic hollow part attracting the peening elements which contact a portion of the internal surface of the non-ferromagnetic hollow part. The magnetic field is disengaged and a second magnetic dipole creates a second magnetic field, thereby causing the peening elements to contact a second portion of the internal surface. The magnetic dipoles are repeatedly turned on and off, thereby causing repeated impact within the interior of the hollow part until the internal surface attains a predetermined stress level.Type: GrantFiled: September 9, 1998Date of Patent: September 14, 1999Assignee: United Technologies CorporationInventors: Karl M. Prewo, Pedro Sainz de Baranda, Vincent C. Nardone
