Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 5 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“Claim 1 of Richman Patent No. 2,938,558 Preamble: A highly noise-immune synchronizing-signal separator system for a television receiver comprising: [A] First means for supplying a negatively modulated television signal including picture-signal components and synchronizing pulses which tend to be accompanied by unwanted noise signals greater in amplitude than the synchronizing pulses; [B] second means coupled to said first means for developing a potential representative of and which varies dynamically with the amplitude of said synchronizing pulses; [C] synchronizing-signal separating means responsive to said first means and dynamically responsive to said potential for separating said synchronizing pulses above the maximum level of said picture-signal components regardless of variations in the amplitude of said synchronizing pulses; [D] and means coupled to said first and second means for rendering said separating means inoperative in response to the occurrence of said noise signals.”
1 later decision quote this exact passage“* * * the grid tends to maintain itself at such a d-c potential that zero bias corresponds to the maximum positive peaks of the signal, or in this case, the top of the synchronizing impulses. If the amplitude of the impulses is sufficient so that black corresponds to plate current cutoff, only the synchronizing impulses are amplified, the rest of the signal occurring beyond cutoff.”
1 later decision quote this exact passage“This, however, cannot be done where an automatic volume control voltage is being applied to the tube.”
