"KInkless" refers not to a sine wave but to the actual plotted anode/grid curves of the tube under measurement.
A triode is linear, but tetrodes had a "kink" in the curve, which can be found in the radiotron Designer's Handbook.
The pentode was designed to eliminate this kink and patented, to avoid paying licensing fees, US companies developed the beam tetrode that effectly had the same "kinkless" curves.
