Title: Improvements in record card mark sensing apparatus
IPC: G11C19/20
Filed: 1955-03-29
Abstract: 766,309. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 29, 1955 [March 31, 1954], No. 9150/55. Class 106 (1). Apparatus for sensing marks upon record cards and performing operations (such as punching) upon them whilst in motion includes a delay device to compensate for separation between the sensing and the punching positions, in which a first discharge tube G1, Fig. 1, is arranged to be fired on receipt of a sensing impulse together with a closure of a cam contact N2 and a second discharge tube G2 is arranged to be fired upon receipt of a pulse generated by the said first tube ceasing to conduct together with closure of a further cam contact. The punching device serves to punch holes corresponding to conductive marks placed on the card. The delay device enables brushes, reading the card at one position in its path, to control the punching mechanism operating at another position along its path. Each data position on the card has a reading brush and associated punching mechanism connected through the delay device described. As shown in Fig. 1, conducting brushes Ba, Bi, Ba read the conducting marks on the card K, the outside brushes Ba being connected through cam contacts N1 to a + 125 volt line so that when a mark passes the brushes, a positive pulse is sent by brush Bi to the first grid of gas-filled tube. G1 through resistor R 1. This grid is normally held negative by a connection through resistor R5 to a grid bias line at - 25 volts. The posi. tive pulse from brush Bi causes the tube G1 to fire, the current passing from earth line OV through contacts N2 (closed), through tube G1 and resistor R2 to 125 volt line. The cathode and second grid of tube Glare connected to the earth line through contacts N2 to the 125 volt line through a resistor and to the first grid through condenser C1. The anode is connected through condenser C2 to resistors R3, R6, one connected to the first grid of tube G2 and the other connected to the grid bias line. When contacts N2 open, the tube G1 ceases to be conductive and the current ceases in resistor R2 so that an increased positive voltage is applied to condenser C2 sufficient to overcome the negative bias on the first grid and cause the tube G2 to fire. The cathode current of this tube has parallel circuits to the earth line, one through resistor R4 and cam contacts N3 and the other through a diode D, the pick-up winding St of a punch magnet and cam-contacts N4. Contacts N3 close before contacts N2 open so that when the tube G2 fires current passes through these contacts. When contacts N4 close, part of the current is diverted through the coil St to energize the punch magnet. The diode D prevents reverse flow of current. The anode of tube G2 is connected to a + 55 volt line to which the winding St is also connected through a condenser-resistor circuit. Use of the diode D may be avoided by using a circuit as in Fig. 2 (not shown).
