Patent number: 10370900Abstract: This disclosure describes methods and systems for remote control of stroke length and frequency of percussion apparatus, such as a rock hammer drill. At a high level, the hammer drill is allowed to stay at a default low stroke length and high frequency to avoid applying excessive cyclic stress to the housing of the hammer drill and can be controlled to operate at a long stroke length and low frequency when the hammer drill has engaged the target material. The long stroke length and low frequency during operation can be initiated when a sufficient forward feed pressure is provided. While the hammer drill is idling or retracting, the forward fee pressure is not sufficient for the long stroke length operation and thus the drill operates at the default state and at a safe stress level to avoid premature damage.Type: GrantFiled: July 29, 2016Date of Patent: August 6, 2019Assignee: TEI ROCK DRILLS, INC.Inventor: William N.

Patent number: 8173946Abstract: A method of defeating an incoming missile, such as a rocket propelled grenade, includes soft launching an interceptor missile, and then using pitch over motors of the interceptor missile to alter course of the missile to a desired interception direction. By launching at a relatively slow speed, such as a speed less than or equal to 40 m/sec (130 ft/sec), the interceptor missile may reach the desired interception direction within 250 milliseconds of launch. The interceptor missile may be able to cover substantially all interception directions over a hemisphere or greater extent around a launch location. For example, the interceptor missile may be launched vertically from a ground vehicle, and be capable of altering course to any above-ground trajectory within 250 milliseconds.Type: GrantFiled: August 26, 2008Date of Patent: May 8, 2012Assignee: Raytheon CompanyInventors: William N. Patterson, James H. Dupont, Richard D. Loehr, Henri Y. Kim, Garrett L. Hall, James M. Cook

Patent number: 8028772Abstract: A percussion drill, and methods of using the same, including a shank in mechanical alignment with a piston-hammer and a valve in fluid communication with the piston-hammer. The percussion drill further includes an internal hydraulic dampening system for reducing the velocity of the piston-hammer when the shank is forward of a power position relative to the velocity of the piston-hammer when the shank is in a power position. Preferably, the internal hydraulic dampening system includes mechanical alignment of a portion of the piston-hammer with a port in fluid communication with the valve, operable to reduce fluid flow into an area surrounding the valve when the piston-hammer is forward of its position relative to its normal operation.Type: GrantFiled: January 19, 2010Date of Patent: October 4, 2011Inventors: William N.

Patent number: 7895948Abstract: Embodiments of a buoyancy dissipater and method for deterring an errant vessel are generally described herein. In some embodiments, a volume of gas is generated from a propellant and diffused below a waterline of a vessel. The resulting gas bubble dissipates the buoyancy of the vessel providing a non-lethal deterring effect. The buoyancy dissipater includes a diffuser having radially-positioned diffusion ports to radially diffuse the gas generated by a gas generator below the waterline. In some embodiments, the radially-positioned diffusion ports comprise holes positioned radially around the diffuser to diffuse the gas around the buoyancy dissipater.Type: GrantFiled: February 2, 2010Date of Patent: March 1, 2011Assignee: Raytheon CompanyInventors: James H.

Patent number: 7665514Abstract: A drill stem centralizer and/or breakout wrench includes a frame with opposed hydraulic cylinder actuators mounted on the frame and engaged in with jaw support members for movement toward and away from each other for centralizing or breakout of drill stem sections. The hydraulic actuators are mounted on trunnions which are supported by bearing caps which may be indexed to change the spacing of the opposed actuators to accommodate a wide range of drill stem diameters or cross-sectional shapes. The jaw support members are provided with laterally spaced guide parts which are moveable in slots in the frame to guide the jaw support members for linear reciprocal movement in response to actuation by the hydraulic actuators. The frame may be mounted for limited rotation on a feed beam to effect drill stem breakout operations.Type: GrantFiled: January 11, 2007Date of Patent: February 23, 2010Inventor: William N. Patterson

Patent number: 6464023Abstract: A hydraulic percussion drill includes a piston hammer disposed in a cylinder for reciprocating movement in response to pressure fluid acting continuously on one transverse face of the piston hammer and in response to valving of pressure fluid alternately to an opposed piston face of the piston hammer by a tubular sleeve valve disposed around the piston hammer. The drill includes a percussion bit configured to have a face portion disposed at an acute angle with respect to a plane normal to the bit and the drill central axis. Cooperating spiral splines on the bit and a bit chuck provide for directional drilling using a method which includes causing the bit to receive impact blows without rotating the cylinder housing to initiate a deviated drillhole.Type: GrantFiled: April 3, 2001Date of Patent: October 15, 2002Inventor: William N.
