bars for each digit must be operated, before an attempt is made to drop 

 a card. 



The operating cycle of the relays and the translator in selecting a 

 card and restoring it is then as follows: 



When the translator is first seized the pull-up magnets are energized 

 and when the cards are suspended the latches are operated. The decoder 

 then closes the leads over which the code bar relays operate and they 

 in turn operate the code bar solenoids. When the proper number of 

 these are operated a check for this is made which releases the latch.
