Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
129 words
A probe assembly for electrically testing very small devices and identifying defective devices comprising a support member, an opening extending through said support member, a plurality of contacts mounted on said support member and extending through said opening, marking means including dye container means mounted on said support member; an open-ended capillary extending from said container means through said opening; gas cylinder means for moving said open-ended portion of said capillary, a hole passing through the cylinder sidewall, said capillary extending through said hole, a piston comprising a sphere of lesser diameter than the inside diameter of said cylinder disposed within said cylinder and resting on said capillary, and means for providing gas pressure to said cylinder whereby to actuate said piston and to effect movement of the capillary.

Claim 3
Dependent Claim
106 words
In combination with a probe assembly, a marker comprising dye container means, an open-ended capillary extending from said container means whereby dye flows from said container means to said open end of said capillary, gas cylinder means for moving said open end in a vertical direction, a hole passing through the sidewall of said cylinder, said capillary extending through the hole, a piston comprising a sphere of lesser diameter than the inside diameter of said cylinder disposed within said cylinder and resting on said capillary, and means for providing gas pressure to said cylinder whereby to actuate said piston and to effect movement of the capillary.
