Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
124 words
A combination for drilling a hole in a refractory material and anchoring the drilling tool therein comprising an electromechanical transducer as a source of vibratory-mechanical energy, means for positioning said transducer to produce oscillatory motion substantially perpendicular to the surface of said refractory material, a drilling tool for drilling said hole, means for transferring said vibratory-mechanical energy to said drilling tool, means for guiding said drilling tool, means for positioning a metal alloy in said hole, and means for simultaneously applying constant static force and vibratorymechanical energy to said tool causing high-velocity friction and causing mechanical hysteresis to occur in said tool for a predetermined time thereby causing said tool to heat and melt said metal alloy to anchor said tool in said hole.
Claim 2
Dependent Claim
124 words
A combination for drilling a hole in a refractory material and anchoring the drilling tool therein comprising an electromechanical transducer as a source of vibratory-mechanical energy, means for positioning said transducer to produce oscillatory motion substantially perpendicular to the surface of said refractory material, a drilling tool for drilling said hole, means for transferring said vibratory-mechanical energy to said drilling tool, means for guiding said drilling tool, means for positioning a metal alloy in said hole, and means for simultaneously applying constant static force and vibratorymechanical energy to said tool causing high-velocity friction and causing mechanical hysteresis to occur in said tool for a predetermined time thereby causing said tool to heat and melt said metal alloy to anchor said tool in said hole.
Claim 3
Dependent Claim
28 words
A combination as set forth in claim 1 wherein said drilling tool is a tool having a substantially planar surface which contacts said refractory material to be drilled.
Claim 4
Dependent Claim
16 words
A combination as set forth in claim 2 wherein said tool has an upper threaded portion.
Claim 5
Dependent Claim
29 words
A combination as set forth in claim 2 wherein the cross section of said planar surface perpendicular to the longitudinal axis of said drilling tool is a preselected geometry.
Claim 6
Dependent Claim
19 words
A combination as set forth in claim 4 wherein said cross section of said drilling tool is a circle.
Claim 7
Dependent Claim
19 words
A combination as set forth in claim 4 wherein said cross section of said drilling tool is a rectangle.
Claim 8
Dependent Claim
19 words
A combination as set forth in claim 4 wherein said cross section of said drilling tool is a triangle.
Claim 9
Dependent Claim
19 words
A combination as set forth in claim 4 wherein said cross section of said drilling tool is a hexagon.
Claim 10
Dependent Claim
19 words
A combination as set forth in claim 4 wherein said cross section of said drilling tool is a trapezoid.
Claim 11
Dependent Claim
18 words
A combination as set for in claim 4 wherein said cross section of said drilling tool is irregular.
Claim 12
Dependent Claim
22 words
A combination as set forth in claim 2 wherein the longitudinal cross section of said drilling tool is an inverted T shape.
Claim 13
Dependent Claim
25 words
A combination as set forth in claim 11 wherein a cylinder of metal alloy is positioned over the upper portion of said inverted T-shaped tool.
Claim 14
Dependent Claim
23 words
A combination as set forth in claim 1 wherein said means for transferring said vibratory-mechanical energy to said drilling tool is impact means.
Claim 15
Dependent Claim
21 words
A combination as set forth in claim 1 wherein said means for guiding said drilling tool is a linear-motion bearing assembly.
Claim 16
Dependent Claim
32 words
A combination as set forth in claim 14 wherein said means for guiding said drilling tool further comprises means for securing said linear-motion bearing assembly to the node of said electromechanical transducer.
Claim 17
Dependent Claim
68 words
A combination as set forth in claim 13 wherein said means for transferring said vibratory-mechanical energy by said impact means to said drilling tool further comprises positioning one end of said drilling tool through the aperture of said linear-motion bearing and against the transducer tip thereby constraining the motion of said drilling tool to motion substantially colinear with that motion produced at the tip of said electromechanical transducer.
