Patent number: 11084137Abstract: A sled for guiding a common hand router to cut a precision planar surface on a workpiece has plywood frame rails spaced by cradles supporting the workpiece between the frame rails. Base rails riding on the upper edge surfaces of the plywood frame rails are sequentially incrementally advanced at intervals along the frame rails in an X-axis direction by a linear ratchet assembly. A router is reciprocated in Y-axis directions during the intervals between the sequential incremental advances of the base rails, cutting a precision planar surface on the workpiece. The router is adapted to adjust the Z-axis elevation of the router cutter. The sled may be manually operated or automated.Type: GrantFiled: April 23, 2019Date of Patent: August 10, 2021Inventor: Michael F. Henry

Patent number: 9964836Abstract: An aerial camera system including a plurality of main reels, a camera interface/safety reel and a stabilized camera head. The camera head is supported from main cables from the main reels with a safety reel cable providing power, data and video communication between the camera head and a main computer system. Each of the main reels, the camera interface/safety reel and the camera head are in communication with the main computer system, which controls the feeding and reeling in of the main cables. Further, the computer system controls the feeding and reeling in of the safety reel cable, which typically only follows the camera head as it moves in three-dimensional space, but may in emergency mode support the weight of the camera head and be used to slowly pull the camera head up and out of the way so that it does not interfere with any activity below the flight area.Type: GrantFiled: May 15, 2012Date of Patent: May 8, 2018Assignee: SKYCAM, LLCInventors: Patrick J. Bennett, Garret Cook, Matthew R. Jones, Kaveh Ashenayi, Michael F. Henry, Alexander MacDonald

Patent number: 5806402Abstract: In a linear actuator, a cylinder is separated into forward and reverse chambers by a piston. A lead screw is threadedly engaged in the piston and a piston rod connects to the load. A turbine applies torque to the screw to urge the screw toward clockwise or counterclockwise rotation depending on the direction of the piston movement. The tangent of the lead screw helix angle is so substantially equal to the coefficient of friction between the piston and the screw that the torque generated by the turbine does not significantly vary the force exerted on the load and the force on the load does not significantly vary the speed of movement of the load. Variations between the static and dynamic coefficients of friction between the lead screw and the piston can be offset by selection of an appropriate lead angle and friction coefficient in the turbine driven system.Type: GrantFiled: November 22, 1996Date of Patent: September 15, 1998Inventor: Michael F.

Patent number: 5680806Abstract: A flow control valve has a gate connected between an operating fluid inlet and outlet. An actuator permits manual adjustment of the gate area to allow fluid to pass from the inlet to the outlet at a threshold rate of flow for a threshold pressure at the first inlet. A biasing mechanism cooperable with the gate and linearly responsive to variations in a control pressure applied to a control inlet of the valve constantly automatically readjusts the area of the gate in proportion to the control pressure. In a constant speed pneumatic motor application of the valve, the motor inlet pressure is applied to the control inlet of the valve and the motor outlet pressure is applied to the operating fluid inlet of the valve. A regulator connected to the motor inlet senses the pressure at the motor outlet. In operation, at idle, the threshold flow rate through the valve is selected by manual adjustment of the valve actuator or stem. The load is added and the motor outlet pressure decreases.Type: GrantFiled: August 23, 1996Date of Patent: October 28, 1997Inventor: Michael F. Henry

Patent number: 5593519Abstract: A method of supersolvus forging is described for Ni-base superalloys, particularly those which comprise a mixture of .gamma. and .gamma.' phases, and most particularly those which contain at least about 40 percent by volume of .gamma.'. The method permits the manufacture of large grain size forged articles having a grain size in the range of 50-150 .mu.m. The method comprises the selection of a fine-grained forging preform of a Ni-base superalloy. Supersolvus forging in the range of 0.degree.-100.degree. F. above the alloy solvus temperature then performed at slow strain rates in the range of 0.01-0.001 s.sup.-1. Subsequent supersolvus annealing followed by controlled cooling may be employed to control the distribution of the .gamma.', and hence influence the alloy mechanical and physical properties. The method may also be used to produce location specific grain sizes and phase distributions within the forged article.Type: GrantFiled: July 7, 1994Date of Patent: January 14, 1997Assignee: General Electric CompanyInventors: Charles P.

Patent number: 5556484Abstract: A method of forging Ni-base superalloys is described which avoids the growth of abnormally large grains in the surface region of a forged article. The method involves forging and/or annealing a Ni-base superalloy in a carburizing environment. Forging and/or annealing in a carburizing environment is done to maintain the carbon concentration in the surface region at a level that is sufficient to prevent the depletion of carbides and carbonitrides. The carburizing environment may also be selected so that it is non-oxidizing with respect to aluminum, in order to prevent the depletion of aluminum and the reduction of the .gamma.' phase in the surface region.Type: GrantFiled: April 26, 1995Date of Patent: September 17, 1996Assignee: General Electric CompanyInventors: Charles P.

Patent number: 5547523Abstract: A method of forging to impart a critical amount of retained strain is described for Ni-base superalloys, particularly those which comprise a mixture of .gamma. and .gamma.' phases, and most particularly those which contain at least about 40 percent by volume of .gamma.'. This forging method harnesses nucleation-limited recrystallization, a phenomenon which has been known in the past to produce uncontrolled, non-uniform Critical grain growth, to produce forged articles having a uniform average grain size in the range of about 90-120 microns. The method comprises the selection of a forging preform formed from a Ni-base superalloy. Isothermal subsolvus forging is then used to form a precursor forging which has a near-net shape. The precursor forging is then forged using relatively high strain rate techniques, such as hammer forging, hot die forging or room temperature forging, to impart all or some portion of it with a critical amount of retained strain energy.Type: GrantFiled: January 3, 1995Date of Patent: August 20, 1996Assignee: General Electric CompanyInventors: Charles P.

Method for minimizing nonuniform nucleation and supersolvus grain growth in a nickel-base superalloy
Patent number: 5529643Abstract: A method is provided for obtaining uniform grain growth within .gamma.' precipitation strengthened nickel-base superalloys. The method includes forming a billet having a very fine grain size in order to achieve optimum superplasticity of the superalloy during forging. The article is then heated to a pre-working hold temperature in a manner which prevents coarsening of the microstructure and a loss of superplasticity. The article is then worked, such as by forging, at a temperature below the .gamma.' solvus temperature of the alloy, so as to maintain local strain rates within the article below a critical strain rate for random grain growth, and so as to maintain the strain rate gradient throughout the article below a critical upper limit. After working, the article is subjected to annealing at a temperature which is less than the .gamma.' solvus temperature of the alloy, and for a duration which is sufficient to remove accumulated metallurgical strain in the article.Type: GrantFiled: October 17, 1994Date of Patent: June 25, 1996Assignee: General Electric CompanyInventors: Duk Y.
