Show moreA method of controlling a DC/DC converter to regulate an output voltage from an input voltage source that varies from a fully-charged voltage to a discharged voltage. The method introduced improves the dynamic response of the converter during transients by switching between different converter topologies to spread out voltage spikes, which are an inevitable result of transients. The invention also can improve the efficiency of the DC/DC converter by replacing higher loss modes with combination modes.

Show moreThis project was done as a response to the thriving public performance community at the northern side of Grant park in Chicago, IL. As a former resident of the South Loop a rift was readily perceived between the North and South ends of the park in both venues for entertainment as well as general amenities. This project looked to fill a void on the south end of the park to create both a more welcoming outdoor space for the public but also to create a performance venue that could help bring business and pedestrian traffic to the southern end of the loop.

Show moreA magnetic tape apparatus wherein a capstan drive assembly provides a tape path thereabout and receives a transducer head with a convex face for scanning engagement with the tape. A magnetic shield may be interposed between the capstan and the head where the capstan is of magnetizable steel. The motor, flywheel and capstan form a unitary assembly which preferably includes a bearing for the outer end of the capstan. A endless loop or reel-to-reel tape cartridge configuration may be engaged with the capstan assembly without manual threading. Idler rollers for the capstan are of configuration to tension the tape at the transducer head location, and may be interchanged to tension the tape in either direction of movement. A preferred head is operable with bias of 10 megahertz or more. Sponsorship: IIT Research Institute United States Patent Show less

Show moreThis invention relates to the metallurgy of iron and particularly to the separation and recovery of metals from electric arc furnace (EAF) dusts. While the invention discloses a process for the separation and recovery applicable to zinc, lead, cadmium and antimony contained in such EAF dusts, the invention is particularly applicable to the separation and recovery of zinc. This invention describes a method for reducing the zinc contained in an EAF dust, volatilizing the metallic zinc so produced from the mass of the dust, and reoxidizing the metallic zinc to zinc oxide along with the simultaneous regeneration of hydrogen which can be recycled to treat additional EAF dust.

Show moreA method in a data processing system and apparatus for organizing files, web pages, or web site members organized in a traditional first hierarchical file structure that is on a recordable medium of a data processing system. A user-defined metalabel is assigned to each of the electronic files, web pages, or web site members. The electronic files, web pages, or web site members are organized as a function of the metalabels into a second hierarchical file structure existing simultaneously with the first hierarchical file structure on the recordable medium of the data processing system. The files, web pages, or web site members can be organized or grouped by the metalabels for efficient searching or following conversations of group members on social networking sites.
