Electrical pulse counting systems

Claim 1

A SYSTEM TO ENABLE A COUNTER TO ACCEPT WITHOUT LOSS ELECTRICAL INPUT PULSES DELIVERED OVER TWO INPUT CHANNELS IN EACH OF WHICH THE PULSE SPACING IS AT LEAST TWICE THE MINIMUM ACCEPTABLE TO THE COUNTER INCLUDING FOR EACH CHANNEL AN INPUT-PULSE EXPANDING STAGE FOR DERIVING FROM EACH INPUT PULSE IN THAT CHANNEL AN EXPANDED INPUT PULSE THE DURATION OF WHICH IS NOT LESS THAN SAID ACCEPTABLE MINIMUM SPACING AND NOT GREATER THAN THE DIFFERENCE BETWEEN THE MINIMUM INPUT PULSE SPACING AND THE MINIMUM ACCEPTABLE SPACING, AN OR-GATING STAGE CONNECTED TO THE PULSE EXPANDING STAGES FOR COMBINING THE EXPANDED PULSES IN A COMMON CHANNEL, A FIRST DIFFERENTIATING STAGE CONNECTED TO THE OR-GATING STAGE FOR DERIVING A FIRST EDGE PULSE IN SYNCHRONISM WITH THE LEADING EDGE OF EACH PULSE IN SAID COMMON CHANNEL, AN AND-GATING STAGE CONNECTED TO THE PULSE EXPANDING STAGES FOR PRODUCING AN ANDGATED PULSE DEFINED BY THE OVERLAP IN TIME OF TWO EXPANDED PULSES, ONE FROM EACH CHANNEL, A SECOND DIFFERENTIATING STAGE CONNECTED TO THE AND-GATING STAGE FOR DERIVING A SECOND EDGE PULSE IN SYNCHRONISM WITH THE TRAILING EDGE OF EACH AND-GATED PULSE, STAGES CONNECTED TO THE PULSE EXPANDING STAGES FOR DERIVING A THIRD EDGE PULSE IN SYNCHRONISM WITH THE TRAILING EDGE OF EACH EXPANDED INPUT PULSE, A DELAY STAGE CONNECTED TO THE LAST-MENTIONED STAGES FOR IMPARTING TO EACH OF THE THIRD EDGE PULSES A DELAY LESS THAN THE DURATION OF EACH EXPANDED INPUT PULSE, A TRANSMISSION GATING STAGE CONNECTED TO THE OR-GATING STAGE AND TO THE DELAY STAGE FOR PASSING EACH DELAYED THIRD EDGE PULSE THAT OCCURS DURING THE PRESENCE OF A PULSE IN SAID COMMON CHANNEL, AND OUTPUT CONNECTIONS FROM THE DIFFERENTIATING STAGES AND THE TRANSMISSION GATING STAGE TO THE COUNTER TO PASS AS OUTPUT PULSES TO IT EACH OF THE FIRST AND SECOND EDGE PULSES AND EACH EDGE PULSE PASSED BY THE TRANSMISSION GATING STAGES.

Claim 2

A SYSTEM TO ENABLE A COUNTER TO ACCEPT WITHOUT LOSS ELECTRICAL INPUT PULSES DELIVERED OVER TWO INPUT CHANNELS IN EACH OF WHICH THE PULSE SPACING IS AT LEAST TWICE THE MINIMUM ACCEPTABLE TO THE COUNTER INCLUDING FOR EACH CHANNEL AN INPUT-PULSE EXPANDING STAGE FOR DERIVING FROM EACH INPUT PULSE IN THAT CHANNEL AN EXPANDED INPUT PULSE THE DURATION OF WHICH IS NOT LESS THAN SAID ACCEPTABLE MINIMUM SPACING AND NOT GREATER THAN THE DIFFERENCE BETWEEN THE MINIMUM INPUT PULSE SPACING AND THE MINIMUM ACCEPTABLE SPACING, AN OR-GATING STAGE CONNECTED TO THE PULSE EXPANDING STAGES FOR COMBINING THE EXPANDED PULSES IN A COMMON CHANNEL, A FIRST DIFFERENTIATING STAGE CONNECTED TO THE OR-GATING STAGE FOR DERIVING A FIRST EDGE PULSE IN SYNCHRONISM WITH THE LEADING EDGE OF EACH PULSE IN SAID COMMON CHANNEL, AN AND-GATING STAGE CONNECTED TO THE PULSE EXPANDING STAGES FOR PRODUCING AN ANDGATED PULSE DEFINED BY THE OVERLAP IN TIME OF TWO EXPANDED PULSES, ONE FROM EACH CHANNEL, A SECOND DIFFERENTIATING STAGE CONNECTED TO THE AND-GATING STAGE FOR DERIVING A SECOND EDGE PULSE IN SYNCHRONISM WITH THE TRAILING EDGE OF EACH AND-GATED PULSE, STAGES CONNECTED TO THE PULSE EXPANDING STAGES FOR DERIVING A THIRD EDGE PULSE IN SYNCHRONISM WITH THE TRAILING EDGE OF EACH EXPANDED INPUT PULSE, A DELAY STAGE CONNECTED TO THE LAST-MENTIONED STAGES FOR IMPARTING TO EACH OF THE THIRD EDGE PULSES A DELAY LESS THAN THE DURATION OF EACH EXPANDED INPUT PULSE, A TRANSMISSION GATING STAGE CONNECTED TO THE OR-GATING STAGE AND TO THE DELAY STAGE FOR PASSING EACH DELAYED THIRD EDGE PULSE THAT OCCURS DURING THE PRESENCE OF A PULSE IN SAID COMMON CHANNEL, AND OUTPUT CONNECTIONS FROM THE DIFFERENTIATING STAGES AND THE TRANSMISSION GATING STAGE TO THE COUNTER TO PASS AS OUTPUT PULSES TO IT EACH OF THE FIRST AND SECOND EDGE PULSES AND EACH EDGE PULSE PASSED BY THE TRANSMISSION GATING STAGES.
