Record event numbering module for modular oscillograph

Claim 1

IN A RECORDING OSCILLOGRAPH ADAPTED FOR RECORDING ON A MOVING LIGHT SENSITIVE RECORDING MEDIUM, BY MEANS OF A MOVABLE LIGHT BEAM, A REPRESENTATION OF THE VARIATIONS IN THE VALUE OF AN INPUT SIGNAL APPLIED TO THE OSCILLOGRAPH, APPARATUS FOR RECORDING ON THE MEDIUM MEMBERS IDENTIFYING EVENTS IN THE RECORDED REPRESENTATION COMPRISING A FIRST CYLINDRICAL DIAL MEMBER MOUNTED FOR ROTATION ABOUT ITS AXIS AND HAVING TRANSPARENT PORTIONS AROUND ITS EXTENT DEFINING A FIRST PRESELECTED PROGRESSION OF NUMBERS COMMENCING WITH ZERO, A SECOND CYLINDRICAL DIAL MEMBER JUXTAPOSED IN COAXIAL RELATION TO THE FIRST DIAL MEMBER AND MOUNTED FOR ROTATION ABOUT ITS AXIS AND HAVING TRANSPARENT PORTIONS AROUND ITS EXTENT DEFINING A SECOND PRESELECTED PROGRESSION OF NUMBERS, A FLASH SOURCE OF ILLUMINATION, MEANS FOR DIRECTING LIGHT FROM THE SOURCE ALONG A FIRST LIGHT PATH HAVING A PORTION DISPOSED RADIALLY OUTWARDLY OF AND THROUGH THE DIALS, A LENS DISPOSED ALONG THE FIRST PATH RECEIVING LIGHT FROM THE SOURCE VIA THE DIALS, MASK MEANS ALONG THE FIRST PATH BETWEEN THE SOURCE AND THE LENS FOR PASSING TO THE LENS ONLY THE LIGHT PASSING THROUGH THOSE TRANSPARENT PORTIONS OF THE DIALS WHICH ARE ALIGNED WITH EACH OTHER ALONG THE FIRST PATH BETWEEN THE SOURCE AND THE LENS, THE ALIGNED TRANSPARENT PORTIONS DEFINING A COMPOSITE NUMBER WHICH INDICATES AN EVENT NUMBER, THE LENS BEING ADAPTED FOR FOCUSING AN IMAGE OF THE COMPOSITE NUMBER ON THE RECORDING MEDIUM, MEANS DEFINING A SECOND LIGHT PATH FROM THE FLASH SOURCE TO THE LENS, THE SECOND PATH HAVING A PORTION OPERATIVELY PARALLEL TO SAID PORTION OF THE FIRST PATH, AN IDENTIFYING MASK MEMBER DISPOSED IN THE SECOND PATH ALONG SAID PORTION THEREOF AND HAVING TRANSPARENT PORTIONS DEFINING PRESELECTED INFORMATION CHARACTERS, MEANS UNITING THE FIRST AND SECOND LIGHT PATHS AND COMBINING THE IMAGES OF THE PRESELECTED INFORMATION CHARACTERS WITH THE IMAGE OF THE COMPOSITE NUMBER FOR PRESENTMENT OF THE COMBINED IMAGES TO THE LENS, MEANS FOR INDEXING THE FIRST DIAL ANGULARLY AN AMOUNT CORRESPONDING TO THE DISTANCE BETWEEN SUCCESSIVE NUMBERS OF THE FIRST PROGRESSION IN RESPONSE TO THE OCCURRENCE OF EACH EVENT TO BE NUMBERED SO AS TO CAUSE THE RESPECTIVE NUMBERS IN THE FIRST PROGRESSION TO APPEAR SEQUENTIALLY AS A COMPONENT OF THE COMPOSITE NUMBER, MEANS FOR INDEXING THE SECOND DIAL ANGULARLY AN AMOUNT CORRESPONDING TO THE DISTANCE BETWEEN SUCCESSIVE NUMBERS OF THE SECOND PROGRESSION IN RESPONSE TO AND ON COMPLETION OF THE CYCLING OF THE NUMBERS OF THE FIRST PROGRESSION PAST A GIVEN LOCATION SO THAT THE RESPECTIVE NUMBERS OF THE SECOND PROGRESSION APPEAR SEQUENTIALLY AS A COMPONENT OF THE COMPOSITE NUMBER, AND MEANS OPERABLE UPON EACH INDEXING OF THE FIRST DIAL TO CAUSE THE FLASH SOURCE OF ILLUMINATION TO EMIT LIGHT FOR A PREDETERMINED PERIOD OF TIME.
