Patent number: 7849813Abstract: An apparatus for applying a liquid to a moving web has an applicator element having a surface extending transverse to the web-travel direction and positioned to contact the moving web. Liquid applied to the surface is transferred to the moving web where the moving web contacts the surface. A support spaced in the web-travel direction from the applicator element has a plurality of guides extending transverse to the web-travel direction, with at least some of the guides overlapping others of the guides. Respective shields slidable in the guides transverse to the direction extend between the web and the surface so that where the shields extend between the moving web and the surface there is generally no transfer of the liquid from the surface to the moving web. Respective adjusters connected to the shields shift same in the respective guides between positions spaced from one another to positions at least partially overlapping one another.Type: GrantFiled: April 24, 2007Date of Patent: December 14, 2010Assignee: Reifenhauser GmbH & Co. KG MaschinenfabrikInventors: Thomas Fett, Walter Kühn

Patent number: 7849902Abstract: An apparatus for making a spunbond web has a foraminous deposition belt, a system for depositing fibers on the belt such that some of the fibers engage through the belt, and an output roller over which the belt is spanned for normally advancing an upper stretch of the belt in a transport direction toward the output roller. The output roller has a radially outwardly directed outer surface engaging the belt and formed with a profiling in turn formed by high spots contacting the belt and low spots out of contact with the belt so that fibers engaged through the belt are only pinched between the belt and the output roller at the high spots. The web is pulled downstream off the belt at the output roller.Type: GrantFiled: June 27, 2008Date of Patent: December 14, 2010Assignee: Reifenhauser GmbH & Co.

Patent number: 7535408Abstract: A method and apparatus is operative for multiple target detection in a radar system which employs a radar waveform of two or more frequency diverse subpulses. The apparatus adds coherent processing of the subpulse echo signals to determine the presence of multiple scattering centers within the radar resolution cell. The subpulses are coherently combined and one can then estimate the number of scattering centers by forming a sample covariance matrix between the subpulse frequency channels and then performing an Eigenvalue decomposition. The resulting Eigenvalues represent the signal strengths of the scattering centers when the associated Eigenvectors correspond to the optimal subpulse weights associated with that signal. A single strong Eigenvalue indicates a single target while two or more strong Eigenvalues or those Eigenvalues larger than the noise related Eigenvalues or a threshold, indicates the presence of multiple targets.Type: GrantFiled: August 31, 2007Date of Patent: May 19, 2009Assignee: Lockheed Martin CorporationInventor: Walter A.
