Apparatus And Method For Determining The Proportion Of Defective Wire In A Length Of Moving Wire
US Patent:
3983371, Sep 28, 1976
Filed:
Jan 6, 1975
Appl. No.:
5/538869
Inventors:
J. Donald Siranni - Sugar Run PA
Charles W. Smith - Bethel Park PA
Charles W. Smith - Bethel Park PA
Assignee:
GTE Sylvania Incorporated - Stamford CT
International Classification:
G01B 1932, G01N 2782
US Classification:
2351513
Abstract:
An apparatus and method are disclosed for determining the proportion of defective wire in a length of wire moving along an established path. The apparatus comprises a first detection means for providing a first signal indication of the rate of travel of said wire, a first summing means for providing a second signal representative of the length of said wire, a second detection means for providing a third signal indicative of defective portions within said wire, a second summing means for providing a fourth signal representative of the length of said defective portions, and a computation means for providing an output indication representative of the proportion of said length of said defective portions to the length of said wire. The method comprises the steps of detecting the rate of travel of said wire, providing a signal representative of the length of said moving wire, detecting the defective portions of said wire, providing a signal representative of the length of said defective portions, and computing the described signals to provide an output indication representative of the proportion of said defective lengths to the length of said wire.
Automated Inspection Apparatus And Method
US Patent:
3989386, Nov 2, 1976
Filed:
Jan 15, 1975
Appl. No.:
5/541234
Inventors:
Charles W. Smith - Bethel Park PA
Assignee:
GTE Sylvania Incorporated - Stamford CT
International Classification:
G01N 2130
US Classification:
356156
Abstract:
There is disclosed an automatic apparatus for sequentially inspecting a plurality of selected areas of an apertured material. The apparatus comprises a light determination means including an established light source and a positioned light detection means, a movable retention means for retaining the apertured material, and a control means for actuating the light determination means and the movable retention means whereby the selected areas of the apertured material will be sequentially positioned between the light source and the light detection means whereupon light is projected through each of said areas. The light passing through the areas is detected by said light detection means. A method for inspecting is also disclosed.
