20080308582	Method of making aerosol valve mounting cups and resultant cups - Metal discs, preferably circular, are cut to a precise diameter and drawn to a preform with a channel and skirt for an aerosol valve mounting cup. The preform then undergoes further forming operations at stations in a press system. “Bumping” is carried out on the skirt edge at a station, to eliminate non-burr trimming of the cup edge, save material and obtain a carefully controlled skirt height and a substantially even skirt edge with minimized earring. The resultant cup terminating skirt edge is characterized by reformed metal. A further coaxing or pinch-cut operation may be performed on the cup skirt.	12-18-2008

20110044236	SATELLITE COMMUNICATIONS SYSTEM FOR PROVIDING GLOBAL, HIGH QUALITY MOVEMENT OF VERY LARGE DATA FILES - A system for providing communication services between geographically disbursed source and destination terminals includes at least one airborne or spaceborne wireless communication device, such as a satellite. The wireless communication device is configured to store and forward large data files of at least an aggregated 10 gigabytes. The wireless communication device includes a wireless transceiver for communicating with the source and destination terminals over at least one high bandwidth channel. A mass data storage device stores the large data files for a predetermined period of time that is greater than approximately two minutes. At least one processor is coupled among the mass data storage and wireless transceiver. The processor is configured to control receipt of a large data file from the source terminal and to transmit it to the destination terminal as the wireless communication device nears the destination terminal.	02-24-2011
