Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
246 words
An apparatus for determining the proportion of defective wire in a length of wire moving along an established path, said apparatus comprising: first detection means positioned relative to said established path of travel of said moving wire for providing a first pulse signal having a pulse rate proportioned to the rate at which said wire travels along said path; first summing means including a binary counter operatively connected to said first detection means for counting the pulses of said first signal and for providing a second signal in digital output form representative of the length of said wire moving along said established path; second detection means positioned relative to said established path for providing a third signal indicative of defective portions of said moving wire; second summing means including a binary counter operatively connected to said first and second detection means for receiving said first and third signals respectively, for counting said pulses included in said first signal in response to enablement by said third signal, and for providing a fourth signal in digital output form representative of the length of said defective portions of said wire moving along said established path; and computation means operatively connected to said first and second summing means for receiving said second and fourth signals respectively, and for providing an output indication of a ratio thereof representative of the proportion of said length of said defective portions of said wire to said length of wire moving along said established path.
Claim 2
Independent Claim
246 words
An apparatus for determining the proportion of defective wire in a length of wire moving along an established path, said apparatus comprising: first detection means positioned relative to said established path of travel of said moving wire for providing a first pulse signal having a pulse rate proportioned to the rate at which said wire travels along said path; first summing means including a binary counter operatively connected to said first detection means for counting the pulses of said first signal and for providing a second signal in digital output form representative of the length of said wire moving along said established path; second detection means positioned relative to said established path for providing a third signal indicative of defective portions of said moving wire; second summing means including a binary counter operatively connected to said first and second detection means for receiving said first and third signals respectively, for counting said pulses included in said first signal in response to enablement by said third signal, and for providing a fourth signal in digital output form representative of the length of said defective portions of said wire moving along said established path; and computation means operatively connected to said first and second summing means for receiving said second and fourth signals respectively, and for providing an output indication of a ratio thereof representative of the proportion of said length of said defective portions of said wire to said length of wire moving along said established path.
