Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
145 words
A MONITORING DEVICE FOR USE IN CHECKING SPACING BETWEEN SUCCESSIVE ARTICLES IN A CONTINUOUS STREAM ALONG A DEFINED PATH, COMPRISING, IN COMBINATION, MEANS LOCATED ON ONE SIDE OF SAID PATH FOR PROJECTING A BEAM OF RADIATION ACROSS SAID PATH, RADIATION-SENSITIVE DETECTOR MEANS ARRANGED ON THE OTHER SIDE OF SAID PATH TO RECEIVE SAID BEAM, AND A.C. CIRCUIT MEANS CONNECTED TO RECEIVE AN ELECTRICAL OUTPUT FROM SAID DETECTOR MEANS, SAID BEAM AND SAID DETECTOR MEANS BEING PLACED AT A SINGLE STATION ALONG SAID STREAM SO THAT THE BEAM IS INTERRUPTED BY ARTICLES PASSING IN SAID STREAM THEREBY TO DELIVER AN ELECTRICAL OUTPUT PULSE WHENEVER SAID BEAM IS RECEIVED AT A GAP BETWEEN TWO SUCCESSIVE PASSING ARTICLES, SO AS TO PRODUCE A SUCCESSION OF ELECTRICAL PULSES OF UNIFORM AMPLITUDE BUT OF DURATION DEPENDENT UPON THE LENGTHS OF GAPS BETWEEN SUCCESSIVE ARTICLES, AND SAID A.C. CIRCUIT MEANS COMPRISES
