Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
181 words
An electronic high frequency pulse generator, having a pulse rate synchronized with the cycles of an alternating current source comprising voltage limiter means, rectifier diode means and capacitor means, said rectifier diode means being in parallel with said voltage limiter means such that one of their common terminals is connected to one of the terminals of said alternating current source and the other of their common terminals is connected in series with said capacitor means, said capacitor means having its other terminal connected to the other terminal of said alternating current source wherein during first half-cycles of the alternating current when the rectifier diode means is conductive, the current is stored by the capacitor means which remains charged after the said first half-cycles terminates and during a second half-cycles of said alternating current when said rectifier diode means is non-conductive, a polarized overvoltage is established across the terminals of said limiter means to fire said limiter means and thereby discharge the energy stored in said capacitor means, thereby producing high frequency pulses which are repeated every other half-cycle of alternating current.
Claim 2
Dependent Claim
181 words
An electronic high frequency pulse generator, having a pulse rate synchronized with the cycles of an alternating current source comprising voltage limiter means, rectifier diode means and capacitor means, said rectifier diode means being in parallel with said voltage limiter means such that one of their common terminals is connected to one of the terminals of said alternating current source and the other of their common terminals is connected in series with said capacitor means, said capacitor means having its other terminal connected to the other terminal of said alternating current source wherein during first half-cycles of the alternating current when the rectifier diode means is conductive, the current is stored by the capacitor means which remains charged after the said first half-cycles terminates and during a second half-cycles of said alternating current when said rectifier diode means is non-conductive, a polarized overvoltage is established across the terminals of said limiter means to fire said limiter means and thereby discharge the energy stored in said capacitor means, thereby producing high frequency pulses which are repeated every other half-cycle of alternating current.
Claim 3
Dependent Claim
51 words
An electronic high frequency pulse generator according to claim 1, which comprises one or more induction coil means at the terminals of said alternating current source such that said induction coil means acting as choke coils for the high frequencies generated by the pulse generator without interfering with the alternating current.
Claim 4
Dependent Claim
63 words
An electronic high frequency pulse generator, according to claim 1, wherein one or more capacitor means are included in the output of said generator for allowing the passage of the high frequencies generated by the generator, said capacitor means acting as decoupling capacitors for the alternating current source thereby allowing a high frequency pulse to be generated without shortcircuiting the alternating current source.
Claim 5
Dependent Claim
147 words
An electronic high frequency pulse generator having a pulse rate synchronized with the cycles of an alternating current source comprising a voltage limiter means, two rectifier diode means having a common terminal connected to a first terminal of said alternating current source, said rectifier diode means being coupled to said common terminal such that said diodes conduct in opposite directions, said voltage limiter means being connected across the terminals of said rectifier diode means which are not connected to said common terminal, said pulse generator further comprising a first capacitor means connected between one of said two rectifier diode means and a second terminal of said alternating current source and a second capacitor means connected between the other of Said two rectifier diode means and a second terminal of said alternating current source, whereby said pulse generator produces a pulse for every half-cycle of said alternating current.
Claim 6
