Abstract: 841,763. Selective perforating machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 11, 1956 [Dec. 14, 1955], No. 37839/56. Class 31 (2). A selective perforating machine comprises a plurality of punches operable for perforating a record card according to a desired code, interposer means selectively operable for conditioning the punches, means for actuating the conditioned punches, and further means operable by conditioning of punches in excess of a prescribed number for preventing perforating. The circuit shown, which is designed particularly for use with the punching machine disclosed in Specification 684,273, which is referred to, for preventing multiple perforation where only single perforation is required includes punch interposer magnets 0-9, 11 and 12, an error relay 26, gas tubes T1, T2, a ferrite core 40, a transformer core 54 and a manual switch 44. In operation and with the switch 44 moved to the ON position, at a certain point in the card feed cycle, cam contacts CF4 close to cause the tube T1 to conduct and the core 40 to be switched to a zero state. If the circuits to more than one interposer magnet are completed, the state 1 of the core 40 is reversed which causes the tube T2 to conduct, the error relay 26 to be energized and an error light 58 to be switched on. As a result, the interposer magnet circuit is broken so that the interposer magnets do not become fully energized and the erroneous punching does not occur. When the switch 44 is moved to the OFF position, the multiple punch prevention circuits are disabled.
