Patent number: 9746269Abstract: One embodiment of a gun configured with the soft recoil system comprises a plurality of recoiling parts that initially moves in the direction of the projectile being fired before moving in a direction opposite to that of a projectile during the firing of the round. The soft recoil system throttles the movement of the recoiling parts such that the energy expended during the firing of the round is spread over a longer time period and a longer distance than would normally occur. The soft recoil system stores at least a portion of the energy transferred to the recoiling parts and the user may selectively release at least a part of that portion of energy to offset the energy imparted to the gun during the firing of the next round.Type: GrantFiled: July 20, 2015Date of Patent: August 29, 2017Assignee: Mandus Group, Ltd.Inventors: Kenneth Wynes, Gary Bowrey

Patent number: 6619930Abstract: A system and method for compressing gas uses a hydraulic pump and a hydraulic accumulator to compress gases in gaseous form. The accumulator is divided into a hydraulic chamber and a pneumatic chamber. The pneumatic chamber of the accumulator can be pneumatically connected to a gas supply and a gas receptacle that needs filled. One-way directional flow valves are used to permit the flow of gas from the gas supply to the pneumatic chamber and from the pneumatic chamber to the gas receptacle, but to prevent the flow of gas in the opposite direction. A motor drives the hydraulic pump, which moves pressurized oil into the hydraulic chamber of the accumulator. The pressurized oil within the hydraulic chamber of the accumulator compresses the gas within the pneumatic chamber of the accumulator, forcing the into a tank or other receptacle that needs filled. The invention can be used to compress a variety of gases at different flow rates, volumes, and pressures.Type: GrantFiled: April 17, 2001Date of Patent: September 16, 2003Assignee: Mandus Group, Ltd.Inventors: Keith Michael Jansen, Kris Martin Jansen
