| 20080271944 | Silencer tube with internal stepped profile - An apparatus which provides for, noise suppressor tube with an internal tapered profile and baffle core which has an external tapered profile machined and designed to minimize friction between the two opposing surfaces which will better facilitate the disassembly of the noise suppressor unit after use. | 11-06-2008 |
| 20090050403 | Black box orientation apparatus - An apparatus and method to install and index an eccentric noise suppressor. Once a noise suppressor is threadedly secured about the bore of a firearm a retention collar may be released by un-securing a retention cap. Releasing the tension which is placed on the retention collar affords the user an option of orienting the noise suppressor to any position which may be achieved by rotating the noise suppressor about the longitudinal axis of the barrel. This allows the user to place an eccentric noise suppressor in a position which does not obscure the sites of a handgun. | 02-26-2009 |
| 20090139795 | Method of assembly for sound suppressors - Provided is a method of assembly for a noise suppressor using specific welding and assembly procedures. By welding the inner portion of a noise suppressor to form a semi complete core an outer tube can then be placed over said core to reinforce the noise suppressor as a whole. The described process allows for an overall reduction of tube wall thickness and provides for a reduction of weight. By affixing each baffle, spacer, end cap and mount together as a whole the strength of the entire unit is multiplied. My method is not restricted to any particular baffle technology but may in fact be incorporated into any design where circumferential fusion welds may be used. | 06-04-2009 |
| 20100163336 | CONTROLLED-UNAIDED SURGE AND PURGE SUPPRESSORS FOR FIREARM MUZZLES - A Controlled Unaided Surge and Purge Suppressor for firearms uses the blast and plume characteristics inherent to the ballistic discharge process to develop a new two-step controlled surge and purge system centered around advanced mixer-ejector concepts. The blast surge noise is reduced by controlling the flow expansion, and the flash effects are reduced by controlling inflow and outflow gas purges. This is a C-I-P application. In the preferred C-I-P embodiment, the blast surge is mitigated via a slotted mixer nozzle; a first expansion chamber; a generally “wagon-wheel” shaped blast baffle with a vent hole; a series of alternating baffles, with vent holes, strategically located along the suppressor's inner wall surface; a second expansion chamber; and an exit opening. This preferred C-I-P embodiment contains no “outside” vent holes (i.e., throughbores) which extend through the suppressor's outer or longitudinal wall. Instead of ingesting ambient air through such throughbores and mixing that air with the muzzle gases, as shown in the parent application, the preferred C-I-P embodiment ingests and mixes chamber gases and contaminants with the muzzle gases while allowing fluid flow through and out the suppressor. It too though can control or eliminate the Mach disk. | 07-01-2010 |

| 20120080261 | Sound and Flash Suppressor for Firearms - A gun silencer comprises and outer tube having and single inner vacuum chamber or multiple vacuum chambers that creates a vacuum enclosed volume for the gases to expand into, so the pressure of the gas that exits the suppressor is reduced significantly; therefore, the sound of the gun firing is more silent than conventional silencers.

The inner vacuum chamber reduces the pressure wave caused at the end of the firearm's barrel. When the firearm is discharged the gases fill the vacuum chamber instead of exiting at normal atmospheric pressure level. As the bullet continues its travel through the distal end of the suppressor, it will perforate the vacuum seal and continue its flight path. | 04-05-2012 |
