Translator for processing meter telemetry recording containing power loss pulses

A translator for processing meter telemetry magnetic recording tapes containing time interval and power loss pulses recorded in either of two formats, wherein a first format includes the time interval pulses and the power loss pulses recorded with first and second waveforms, respectively, and wherein a second format includes only time interval pulses recorded with one of said first and second waveforms, said translator comprising:

• pulse shaping means receiving the recorded waveforms and producing a first signal pulse corresponding to said first waveform and a second signal pulse corresponding to said second waveform, said first signal pulse having a longer duration than said second signal pulse;
• pulse duration recognizing means receiving said first and second signal pulses and producing an output pulse at a first terminal only when said first signal pulse is applied to the recognizing means and further producing an output pulse at a second terminal only when said second signal pulse is applied to the recognizing means;
• first gating means responsive to said output pulses produced at both of said first and said second terminals and transferring pulses corresponding to the time interval pulses to a first output for further processing in the translator;
• a second gating means responsive to said output pulses produced at one of said first and second terminals and transferring a pulse corresponding to a power loss pulse to the a second output for further processing in the translator;
• and
• means selectively enabling and disabling said first and second gating means in at least two conditions, said first condition effecting response to said second recording format to only produce said time interval pulses at said first output, and said second condition effecting response to recordings in said first format to produce said time interval pulses and said power loss pulses at said first and second outputs, respectively.
