Abstract
Abstract Circuitry for providing output power for a load such as neon lights, one of the lights being cyclically flashed and the other being constantly illuminated. The circuitry includes separate rectifiers for the two loads, to minimize and virtually eliminate any flicker in the constant portion of the circuit which might otherwise exist incident to the cyclic flashing or interrupting elsewhere in the circuit. The output is desirably at about 20-23 kHz., which is approximately optimum frequency for neon and similar lighting applications, at an initial voltage of about 1600 volts and a running voltage of about 2900 volts for a typical 8-foot neon tube.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
88 words
A power supply for neon lights of the like fed from an AC source comprising: first rectifYing means fed by the source for producing a first DC output; flasher means fed by said first DC output for cyclically interrupting power and producing an interrupted DC output; inverter means fed by said interrupted DC output for generating an interrupted AC output; second rectifying means fed by said source for producing a second DC output; and inverter means fed by the second rectifying means for generating a constant AC output.
Claim 2
Dependent Claim
88 words
A power supply for neon lights of the like fed from an AC source comprising: first rectifYing means fed by the source for producing a first DC output; flasher means fed by said first DC output for cyclically interrupting power and producing an interrupted DC output; inverter means fed by said interrupted DC output for generating an interrupted AC output; second rectifying means fed by said source for producing a second DC output; and inverter means fed by the second rectifying means for generating a constant AC output.
Claim 3
Dependent Claim
17 words
The invention as defined in claim 1, wherein the AC source has a frequency of 60 Hz.
Claim 4
Dependent Claim
23 words
