Abstract
Abstract The thickness of a formed glass container is evaluated around its wall periphery by making a selected sampling of voltage data. An encoder is used which displaces the periphery past a sensor and sampling is synchronized with the pulses of the encoder. When a seam is detected, sampled data is ignored for a chosen number of pulses prior to as well as following and the number of pulses is set by defining the diameter of the container.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
149 words
A glass container inspection machine for inspecting the wall thickness of a round bottle having vertical seams comprising: a test station for generating a continuous voltage signal representative of the thickness of a portion of the round bottle located at the test station, mechanical handling means for displacing a portion of the wall of a round bottle past said test station, encoding means for issuing pulses relative to surface displacement as said container passes through said test station, means for sampling the voltage signal whenever said encoding means issues a pulse during a predetermined sampling period, means for detecting the presence of a wall seam at said test station, means for ignoring the sampled voltage for a first selected number of pulses prior to the detection of a seam, and means for ignoring the sampled voltage for a second selected number of pulses following the detection of the seam.
Claim 2
Dependent Claim
