Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
180 words
An apparatus for spectroscopically analyzing the composition of a workpiece, said apparatus comprising: a support; a sleeve mounted on said support and having an open end engageable with a surface of the workpiece and formed with a laterally open cutout; an electrode on said support and having an electrode tip limitedly displaceable in said sleeve adjacent said open end thereof; means between said support and said electrode for fixing said electrode in said sleeve with said tip spaced inwardly of said open end thereof; means connected to said electrode for sparking between said surface and said tip when same are spaced apart and said open end abuts said surface; optical means on said support directed through said cutout at the space between said tip and said surface and including a primary slit for transmitting into said support the light of a spark in said space between said tip and said surface; and means in said support including a Rowland grating and a plurality of secondary slits for breaking the light received from said optical means down into an analyzable spectrum.
Claim 2
Independent Claim
180 words
An apparatus for spectroscopically analyzing the composition of a workpiece, said apparatus comprising: a support; a sleeve mounted on said support and having an open end engageable with a surface of the workpiece and formed with a laterally open cutout; an electrode on said support and having an electrode tip limitedly displaceable in said sleeve adjacent said open end thereof; means between said support and said electrode for fixing said electrode in said sleeve with said tip spaced inwardly of said open end thereof; means connected to said electrode for sparking between said surface and said tip when same are spaced apart and said open end abuts said surface; optical means on said support directed through said cutout at the space between said tip and said surface and including a primary slit for transmitting into said support the light of a spark in said space between said tip and said surface; and means in said support including a Rowland grating and a plurality of secondary slits for breaking the light received from said optical means down into an analyzable spectrum.
Claim 3
Dependent Claim
11 words
The apparatus defined in claim 1 wherein said support is portable.
Claim 4
Dependent Claim
11 words
The apparatus defined in claim 1 wherein said sleeve is conductive.
Claim 5
Dependent Claim
21 words
The apparatus defined in claim 3 wherein said support includes a member of insulating material on which said sleeve is mounted.
Claim 6
Dependent Claim
26 words
The apparatus defined in claim 4 wherein said means between said support and said electrode is a screw threaded into said member and engaging said electrode.
Claim 7
Dependent Claim
27 words
The apparatus defined in claim 3, further comprising a tube of insulating material between said electrode and said sleeve, said tube being fixed relative to said sleeve.
Claim 8
Dependent Claim
31 words
The apparatus defined in claim 1 wherein said sleeve has at said open end an end face lying substantially in a plane, said tip being pointed and spaced from said plane.
Claim 9
Dependent Claim
38 words
The apparatus defined in claim 1 wherein said means for sparking is also connected to said sleeve, whereby electrical contact is made between said sleeve and said workpiece on physical engagement between said open end and said surface.
Claim 10
Dependent Claim
35 words
The apparatus defined in claim 8 wherein said means for sparking includes safety means for preventing sparking between said surface and said tip when said open end is out of electrical contact with said surface.
Claim 11
Dependent Claim
20 words
The apparatus defined in claim 1 wherein said optical means includes a lens focused through said cutout at said space.
