As ingenious as this is, can you truly call it simple? I mean just look at the patent alone, it has over 120 listed items and the real production piece probably even more. It is mechanically incredibly complex, combining all kinds of levers, materials, linkages, thermal expansion, small tolerances, reflecting radiation, latches, bimetallic switches. Contrast this with a basic design which can probably be made with 2 or 3 moving parts only: the spring, some latch and a time/heat-controlled relay. Assuming you'd want to replicate this thing with modern equipment, would it be cheaper and simpler with a servo and a µC?
