Patent number: 7690312Abstract: A projectile, including a compacted and sintered mixture of a plurality of tungsten particles and a plurality of iron particles. At least a portion of the plurality of iron particles are bonded together, and no intermetallic compounds or alloys of the tungsten particles and iron particles are formed during the compaction and sintering processes. The final density of the projectile is from about 8.1 grams per cubic centimeter to about 12.1 grams per cubic centimeter, and no substantial densification occurs during sintering. A method of producing such a projectile is also disclosed.Type: GrantFiled: January 20, 2005Date of Patent: April 6, 2010Inventor: Timothy G. Smith

Patent number: 7073425Abstract: A shot pellet that, has an inner core of a material such tungsten carbide, that is coated with a layer of bismuth. This coating is molecularly bonded to the tungsten carbide and is not an alloy. The unique properties of the shot pellet allow its density to be tailored. Under this process, the effective density of the pellet can be made to be identical to lead for direct replacement in current lead loading formulations. Additionally, the density can be made to be lower than lead for shotguns requiring low barrel pressures, or higher than lead for enhanced energy transfer while maintaining the other advantages of the instant invention.Type: GrantFiled: September 17, 2004Date of Patent: July 11, 2006Inventors: James Robert Allen, Michael B Katz

Patent number: 6823798Abstract: Manufacturing processes for articles that are formed from compositions of matter that include powders containing tungsten and at least one binder, as well as articles formed thereby. In some embodiments, the processes include compacting the mixture of powders under a first pressure to yield a desired intermediate structure, then reshaping the structure under a second pressure that is lower than the first pressure to yield the desired article. The compacting steps may include punches and/or dies having different configurations and/or materials of construction. The composition of matter preferably is selected to reflow, or be reshaped, without fragmenting or otherwise disintegrating into discrete particles or particulate. In some embodiments, the compacted intermediate structure and/or final article has an extrusion constant of less than 30,000 psi. In some embodiments, the mixture of powders has an ASTM Hall flowmeter reading for fifty grams through a cone (without tapping) of less than 18 seconds.Type: GrantFiled: October 17, 2003Date of Patent: November 30, 2004Inventor: Darryl D.

Patent number: 6295364Abstract: A digital voice enhancement communication system, including a simplex system, has first and second acoustic zones, and respective microphones and loudspeakers. A voice sensitive gated switch has a first mode supplying the output of a first microphone in the first zone over a first channel to a second loudspeaker in the second zone, and has a second mode supplying the output of a second microphone in the second zone over a second channel to the first loudspeaker in the first zone. First and second noise sensitive bandpass filters and first and second equalization filters are provided in the first and second channels, respectively. Each noise sensitive bandpass filter is a noise responsive highpass filter having a filter cutoff effective at elevated noise levels and reducing bandwidth and making more gain available, to improve intelligibility of speech of a person in the respective zone transmitted from the respective microphone to the loudspeaker in the other zone.Type: GrantFiled: March 30, 1998Date of Patent: September 25, 2001Assignee: Digisonix, LLCInventors: Brian M.
