Patent number: 11201400Abstract: The beamforming system includes a plurality of beamformers operatively coupled to each other. Each beamformer includes a plurality of signal generation units and a plurality of respective delaying units. Each beamformer includes a plurality of multipliers assigned to each delaying unit. Each beamformer includes a plurality of summers configured to receive a respective group of conditioned signals from a respective group of the plurality of multipliers, combine the respective group of conditioned signals and generate a respective phased array output signal. Each of the summers is configured to receive at least another input other than the respective group of conditioned signals. The plurality of beamformers are interconnected such that each of the plurality of summers within each beamformer receives, as the at least another input, a respective phased array output signal from a summer of a different one of the plurality of beamformers. As associated method is also provided.Type: GrantFiled: January 17, 2019Date of Patent: December 14, 2021Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Markus Stahlberg, Alexander Freund, Alfred Wolsfeld

Patent number: 9666941Abstract: A beamforming system comprising a plurality of modular beamformers is provided. The modular beamformers may be operatively coupled to each other (for example, in parallel). Each modular beamformer may comprise a plurality of signal generation units configured to generate signals. Each modular beamformer may further comprise a plurality of delaying units configured to receive the signals and adaptively delay output of the signals. Each modular beamformer may further comprise a plurality of multipliers assigned to the delaying units to generate conditioned signals by adaptively applying weights to the signals output by the plurality of delaying units. Each modular beamformer may further comprise a plurality of summers configured to combine the conditioned signals to generate a phased array output signal.Type: GrantFiled: November 26, 2012Date of Patent: May 30, 2017Assignee: GENERAL ELECTRIC COMPANYInventors: Markus Stahlberg, Alexander Freund, Alfred Wolsfeld

Patent number: 8152882Abstract: A conventional dust-catcher for blast furnace gas comprises a pressure vessel, with a gas inlet and outlet dome (14), a separation chamber (16) and a lower dust hopper (18), and a diffuser pipe (26) extending axially through the gas inlet and outlet dome (14) into the separation chamber (16). To increase the separation efficiency of such a dust hopper (18), it is proposed to centrally arrange a flow deflecting chamber (50, 50?), having a smaller cross-section than the separation chamber (16), in the separation chamber (16), so that there remains an annular settlement chamber (52) between the inner wall of the separation chamber (16). The diffuser pipe (26) is connected to this flow deflecting chamber (50, 50?) so as to axially discharge a downward gas flow into the top end of the flow deflecting chamber (50, 50?), wherein this downward gas flow is deflected upward.Type: GrantFiled: July 22, 2008Date of Patent: April 10, 2012Assignee: Paul Wurth S.A.Inventor: Alfred Wolsfeld
