Abstract
Abstract Registration of the first planar part is achieved with respect to a test specimen carried by a component holder which is provided with foolproof positioning device for the second planar part. The first planar part is fastened to the component holder, the test specimen is removed and may be replaced by a second part. According to an important feature of the invention, registration of the first planar with the test specimen is monitored through visual inspection of an enlarged display of optical marks carried both by the first part and the test specimen.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
An apparatus for the registration of a first planar part carrying two identification marks spaced a distance d apart with a second planar part comprising means for generating two parallel light beams, means to adjust the distance between the two beams to said value d, means to magnify the images of said two beams, means to bring such images closer with respect to one another, a viewing screen to display such images, clamping means to fix the first of said planar part with respect to the apparatus across both said light beams, movable carriage means for said second part comprising a movable holder located on one side of said first part and a removable frame located on the other side of said first part, positioning means to fix said second part within said holder across said two light beams, two drilled holes in said second part spaced by d, mechanical means to displace said carriage until the images of said holes are superimposed on said viewing screen with the images of marks carried by said first part.
Claim 2
Independent Claim
177 words
An apparatus for the registration of a first planar part carrying two identification marks spaced a distance d apart with a second planar part comprising means for generating two parallel light beams, means to adjust the distance between the two beams to said value d, means to magnify the images of said two beams, means to bring such images closer with respect to one another, a viewing screen to display such images, clamping means to fix the first of said planar part with respect to the apparatus across both said light beams, movable carriage means for said second part comprising a movable holder located on one side of said first part and a removable frame located on the other side of said first part, positioning means to fix said second part within said holder across said two light beams, two drilled holes in said second part spaced by d, mechanical means to displace said carriage until the images of said holes are superimposed on said viewing screen with the images of marks carried by said first part.
Claim 3
Independent Claim
188 words
An apparatus for the registration of a first planar part carrying two identification marks spaced a distance d apart with a second planar part comprising means for generating two parallel light beams, means to adjust the distance between the two beams to said value d, means to magnify the images of said two beams, means to bring such images closer with respect to one another, a viewing screen to display such images, clamping means to fix the first of said planar part with respect to the apparatus across both said light beams, movable carriage means for said second part comprising a holder made of a rectangular frame carrying three abutments on two adjacent sides of its inner periphery and one pushing spring attached to each of the other sides, located on one side of said first part and a removable frame located on the other side of said first part, two drilled holes in said second part spaced by d, mechanical means to displace said carriage until the images of said holes are superimposed on said viewing screen with the images of marks carried by said first part.
