Definitions

  • the second card feed cycle is initiated automatically, as will be obvious from the subsequent description of circuits which keep the RID relay energized.
  • the energizing circuit for energizing the ROM clutch magnets for the second card feed cycle extends from line 200 through R90 relay contacts now closed, RIIlb relay contacts now closed, Rla relay contacts now transferred, thence cthrough the Rl4b relay contacts now closed","S2 switch, C2 cam contacts, RCM clutch magnets to line 20L
  • the clutch of the reading unit is now engaged and the card which was fed just to the comparing brushes I is now fed past such brushes for the analyzing of the perforations representing the classification data on such card.
  • RID relay When the RID relay is energized by the start key depression, a holding circuit therefor is provided through RIOc contacts, R24a relay contacts, P6 cam contacts, back to line 200.
  • Relay contacts R24a are closed by R24 relay energized under control of the R2 cam contacts. From Fig. 6 it will be observed that cam contacts R2 close to energize the R24 relay to close the R240. relay contacts just prior to the closure of the P6 cam contacts so that the hold circuit for RIO relay is closed when the P6 cam contacts close at 13.4 at the end of the cycle. The holding circuit remains closed for the end of this cycle and up to 9.4 of the next cycle when cam contacts R2 open.
  • a cyclically operable record reproducing machine comprising pattern record sensing means for sensing zone perforations and numeric perforations combinationally arranged in a column to represent a letter, an emitter for transmitting concurrently with the sensing of said zone perforations differentially timed zone impulses, and concurrently with the sensing of said numeric perforations difierentially timed numeric impulses, means for selecting a zone and numeric impulse representing a searched-for letter, relay comparing means controlled by said emitter and sensing means operable in one comparing opera tion to determine agreement or disagreement between a selected zone impulse and the zone perforation sensed, and in another comparing operation to determine agreement or disagreement between a selected numeric impulse and the numeric perforation sensed, reproducing punching means to effect the reproduction of data on said pattern record to other record material, and means controlled by said comparing means to cause the operation of said reproducing punching means upon agreement being found in both comparing operations.
