Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
A code forming apparatus providing a repetitive code comprising, FIRST PULSE GENERATOR MEANS FOR PRODUCING PULSES WITH A FIRST REPETITION RATE, SECOND PULSE GENERATOR MEANS FOR PRODUCING PULSES WITH A SECOND REPETITION RATE, FIRST GATE MEANS CONNECTED TO THE OUTPUT OF SAID FIRST PULSE GENERATOR MEANS, SECOND GATE MEANS CONNECTED TO THE OUTPUT OF SAID SECOND PULSE GENERATOR MEANS, ENABLING MEANS RESPONSIVE TO A RESET PULSE FOR ALTERNATELY ENABLING BOTH SAID GATE MEANS AND RESPONSIVE TO A RECYCLE PULSE FOR ENABLING SAID FIRST GATE MEANS, CODE FORMING MEANS, CONNECTED TO THE OUTPUT OF BOTH SAID GATE MEANS AND RESPONSIVE TO THE OUTPUT OF AN ENABLED GATE MEANS, FOR PRODUCING A PREDETERMINED NUMBER OF CODE PULSES AND FOR PRODUCING SAID RESET PULSE AFTER SAID PREDETERMINED NUMBER OF CODE PULSES HAVE BEEN PRODUCED, SAID CODE PULSES HAVING A REPETITION RATE RELATED TO THE PULSE REPETITION RATE APPEARING AT THE OUTPUT OF AN ENABLED GATE MEANS, AND RECYCLE MEANS RESPONSIVE TO SAID RESET PULSE FOR PRODUCING SAID RECYCLE PULSE AFTER A PREDETERMINED NUMBER OF SAID RESET PULSES HAVE BEEN PRODUCED.
Claim 2
Dependent Claim
177 words
A code forming apparatus providing a repetitive code comprising, FIRST PULSE GENERATOR MEANS FOR PRODUCING PULSES WITH A FIRST REPETITION RATE, SECOND PULSE GENERATOR MEANS FOR PRODUCING PULSES WITH A SECOND REPETITION RATE, FIRST GATE MEANS CONNECTED TO THE OUTPUT OF SAID FIRST PULSE GENERATOR MEANS, SECOND GATE MEANS CONNECTED TO THE OUTPUT OF SAID SECOND PULSE GENERATOR MEANS, ENABLING MEANS RESPONSIVE TO A RESET PULSE FOR ALTERNATELY ENABLING BOTH SAID GATE MEANS AND RESPONSIVE TO A RECYCLE PULSE FOR ENABLING SAID FIRST GATE MEANS, CODE FORMING MEANS, CONNECTED TO THE OUTPUT OF BOTH SAID GATE MEANS AND RESPONSIVE TO THE OUTPUT OF AN ENABLED GATE MEANS, FOR PRODUCING A PREDETERMINED NUMBER OF CODE PULSES AND FOR PRODUCING SAID RESET PULSE AFTER SAID PREDETERMINED NUMBER OF CODE PULSES HAVE BEEN PRODUCED, SAID CODE PULSES HAVING A REPETITION RATE RELATED TO THE PULSE REPETITION RATE APPEARING AT THE OUTPUT OF AN ENABLED GATE MEANS, AND RECYCLE MEANS RESPONSIVE TO SAID RESET PULSE FOR PRODUCING SAID RECYCLE PULSE AFTER A PREDETERMINED NUMBER OF SAID RESET PULSES HAVE BEEN PRODUCED.
Claim 3
Dependent Claim
59 words
The apparatus of claim 1 wherein said code forming means comprises a binary to binary coded decimal converter means, a four to ten line decoder means responsive to said converter means, gate means responsive to three preselected outputs of said decoder means, and means responsive to a fourth preselected output of said decoder means for forming a reset pulse.
Claim 4
Dependent Claim
41 words
The apparatus of claim 2 wherein said recycle means comprises a binary to binary coded decimal converter means, a four to ten line decoder means, and means responsive to a selected output of said decoder means for forming a recycle pulse.
Claim 5
Dependent Claim
38 words
The apparatus of claim 3 wherein said second pulse generator means comprises a dividing means responsive to the output of said first pulse generator means for producing pulses with a repetition rate lower than said first repetition rate.
Claim 6
Dependent Claim
23 words
The apparatus of claim 4 wherein said predetermined number of code pulses is three and said predetermined number of reset pulses is three.
Claim 7
Dependent Claim
24 words
The apparatus of claim 5 further including a utilization means responsive to the output of said code forming means for providing a visible signal.
