In contradistinction to this the oscillations
in the primary circuit of the Lepel system åse generated by
"quenched" sparks which give rise to extremely short trains
of oscillations, in fact "jerks" or "kicks" rather than
streams of oscillations.
That is to say though both systems aim at radian
ting from the aerial as much wave energy as possible through
the use of coupled circuits, Marconi does this by steadily
fuuding the radiating circuit with a supply of energy ·
-
"stroking" it, so to speak, by the oscillations in the primary circuit which are kept swinging for as long a time as possible;
whilst Lepel reaches the same end by means of frequent but
intermittent "ricks" in the primary circuit, the oscillations
Chused in that circuit being damped out as quickly as possible, allowing the oscillations in the radiating circuit to continue
freely.
Lepel requirus tuned circuits as much as Marconi and unless it cæ, be shew that there is no real novelty in
tuning coupled circuits, which is certainly a possibility, he
may to that extent be said to infringe. We do not think it
can be said that Marconi's patunt covers a quenched spark
system seeing that the possibility of using such a system was
unknown when the patent No.7777 was taken out, and it is also
evident that the use of such a spark mi ** the primary circuit
the antithesis of a conserving cireui'
