Patent number: 7681351Abstract: A hydraulic recoil buffer assembly for a firearm having a receiver and a fixed or collapsible stock assembly including an end cylinder adapted to be secured to the pistol grip or receiver of the firearm and slidably translatable with respect to the extension tube, and a hydraulic shock absorption assembly operative to produce a hydraulic resistance to a rearward movement of the end cylinder during recoil of the firearm. The hydraulic shock absorption assembly has an orifice restricted fluid flow passage and a piston head that compresses a return spring as the end cylinder moves rearward against a recoil coil spring. The recoil buffer assembly stores a portion of the recoil energy through compression of the recoil spring and the return spring, and dissipates a portion of the recoil energy through the resistance provided by fluid flow through the orifice restricted flow passage.Type: GrantFiled: November 15, 2006Date of Patent: March 23, 2010Assignee: Enidine, Inc.Inventors: Brian C.

Publication number: 20100031761Abstract: A mechanical linear actuator having a tubular member that is defined by a housing for rotatably and axially supporting a circular nut, a lead screw is mated to the circular nut so that it can move axially in and out of the tubular member. A torsion spring clutch brake is wound about the circular nut to normally brake the nut and thus prevent the lead screw from moving into or out of the tubular member. An unlocking mechanism can remotely unwind the torsion spring clutch brake to sufficiently release the circular nut and thus allow the lead screw to pass in and out of the tubular member. An adjustable stop is provided for adjusting the stroke of the actuator.Type: ApplicationFiled: August 7, 2008Publication date: February 11, 2010Applicant: Enidine, IncorporatedInventor: Terrance E.

Patent number: 7131786Abstract: This invention relates to a process and a device for the damping of motion between two cylindrical parts sliding with one another in translation and friction. According to this invention, the damping is performed by the application of a force exerted radially perpendicularly to the translation motion of the two parts by at least one elastic segment (13) circling one of the parts (11) and inside the other (12), integral in translation with one of the parts (11) and appplying said frictional force on the other part (12).

Patent number: 7121032Abstract: A recoil pad for a shoulder firearm includes at least one piston member that is caused to move axially from an initial axial position to a second axial position upon application of the recoil force from the firearm. The axial movement of the piston member causes fluid movement within a column relative to a variable or fixed orifice area wherein the fluid movement causes resistance that absorbs the energy. A mechanical and/or hydraulic and/or elastomeric feature returns the piston to the initial axial position upon cessation of the applied recoiling force.Type: GrantFiled: February 3, 2005Date of Patent: October 17, 2006Assignee: Enidine, Inc.Inventors: Terrance E.

Patent number: 7108111Abstract: A shock and vibration isolator that includes a double acting mechanical spring assembly that is mounted to act in parallel with a fluid or liquid spring assembly. The mechanical spring is arranged to provide a first spring rate over a first displacement range and a second spring rate over a further second displacement range. The liquid spring is connected to an accumulator by control circuitry that is under the control of a microprocessor to release stored energy which combines with that of the mechanical spring to rapidly dissipate the input G forces to a level sufficient to protect a substructure.Type: GrantFiled: October 25, 2004Date of Patent: September 19, 2006Assignee: Enidine IncorporatedInventors: Gerald J.

Patent number: 6568514Abstract: A single-use damping mechanism. A piston assembly fits within a chamber defined by a piston receiving member. The distal end of the piston receiving member includes a first and second passages which are disposed in fluidic series between the chamber and the ambient air. The first, inner passage is relatively small and controls the damping time of the mechanism. The second, outer passage is relatively large and holds a sealing assembly that prevents fluid from escaping from the chamber, through the first passage, until the mechanism is to be used. The piston assembly includes a pressure relief assembly, which comprises a cavity filled with a compressible material, into and out of which fluid can flow as necessary to protect the mechanism from temperature related pressure changes, and yet which does not interfere with the damping characteristics of the mechanism.Type: GrantFiled: October 13, 2000Date of Patent: May 27, 2003Assignee: Enidine IncorporatedInventor: Scott J. Tokasz

Patent number: 6513800Abstract: A double acting mechanical shock isolator that includes a stack of friction springs contained within a housing. The stack is retained between the end walls of the housing by a pair of opposed slides. A sleeve passes through the stack and the ends of the sleeve are contained within opposing slides. The ends of the sleeve are connected to the slides by lost motion devices so that the sleeve is engaged by one of the containing slides when the sleeve moves toward the opposing slide and releases the slide when the sleeve moves in the opposite direction so that the stack is loaded in compression when the sleeve is moved axially in either direction.Type: GrantFiled: July 10, 2001Date of Patent: February 4, 2003Assignee: Enidine Inc.Inventors: Brian Charles Bucholtz, Daniel Charles Radice, Scott Joseph Tokasz
