Abstract
Abstract A device for inspecting a glass container to evaluate its wall thickness. The minimum thickness, the maximum thickness and the minimum to maximum thickness ratio are calculated and an inspected bottle is rejected based on one or more of these three parameters.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
146 words
An apparatus for measuring the wall thickness of a glass container, said apparatus comprising; sensing means for producing a signal representative of the thickness of a wall of a glass container presented to it; means for presenting a glass container to said sensing means so that its wall thickness may be sensed; and first means responsive to said sensing means for providing a minimum thickness signal representative of the minimum wall thickness of said container; second means responsive to said sensing means for providing a maximum thickness signal representative of the maximum wall thickness of said container; selecting means for selecting one or more parameters from the group consisting of maximum wall thickness and minimum wall thickness; rejecting means responsive to said minimum thickness signal, said maximum thickness signal, and said selecting means for rejecting a glass container based on said one or more selected parameters.
Claim 2
Independent Claim
146 words
An apparatus for measuring the wall thickness of a glass container, said apparatus comprising; sensing means for producing a signal representative of the thickness of a wall of a glass container presented to it; means for presenting a glass container to said sensing means so that its wall thickness may be sensed; and first means responsive to said sensing means for providing a minimum thickness signal representative of the minimum wall thickness of said container; second means responsive to said sensing means for providing a maximum thickness signal representative of the maximum wall thickness of said container; selecting means for selecting one or more parameters from the group consisting of maximum wall thickness and minimum wall thickness; rejecting means responsive to said minimum thickness signal, said maximum thickness signal, and said selecting means for rejecting a glass container based on said one or more selected parameters.
Claim 3
Dependent Claim
42 words
An apparatus as in claim 1 wherein said selecting means comprises a display means, a computer means for displaying said parameters on said display and input means communicating with said computer for selectively indicating one of said parameters displayed on said display.
Claim 4
Dependent Claim
34 words
An apparatus as in claim 2 wherein said input means further comprises means for assigning a selected value to the one of said parameters that is indicated by said indicating means on said display.
Claim 5
Dependent Claim
38 words
An apparatus as in claim 3 wherein said selecting means further comprises means for rejecting a glass container based on a specific one of said parameters only if the selected value assigned to said specific parameter is non-zero.
Claim 6
Independent Claim
160 words
An apparatus for measuring the wall thickness of a glass container, said apparatus comprising; sensing means for producing a signal representative of the thickness of a wall of a glass container presented to it; means for presenting a glass container to said sensing means so that its wall thickness may be sensed; and first means responsive to said sensing means for providing a first thickness signal representative of the minimum wall thickness of said container; second means responsive to said sensing means for providing a second thickness signal representative of the maximum wall thickness of said container; means for calculating the ratio of minimum to maximum wall thickness, selecting means for selecting one or more parameters from the group consisting of said minimum wall thickness, said second thickness and said ratio; rejecting means responsive to said first thickness signal, said second thickness signal, and said selecting means for rejecting a glass container based on said one or more selected parameters.
Claim 7
Independent Claim
160 words
An apparatus for measuring the wall thickness of a glass container, said apparatus comprising; sensing means for producing a signal representative of the thickness of a wall of a glass container presented to it; means for presenting a glass container to said sensing means so that its wall thickness may be sensed; and first means responsive to said sensing means for providing a first thickness signal representative of the minimum wall thickness of said container; second means responsive to said sensing means for providing a second thickness signal representative of the maximum wall thickness of said container; means for calculating the ratio of minimum to maximum wall thickness, selecting means for selecting one or more parameters from the group consisting of said minimum wall thickness, said second thickness and said ratio; rejecting means responsive to said first thickness signal, said second thickness signal, and said selecting means for rejecting a glass container based on said one or more selected parameters.
