offset filament Explanation: It looks like this is what is meant - the year also tallies more or less with with your subject. "In 1931, this movement reached the point where centered filaments were no longer capable of fulfilling all the lens requirements, and lamps with offset filaments were created." Journal of the Society of Motion Picture Engineers Vol. 19 (1930) The PDF version is almost 40 mb, so it may take a long time to download. There's lots of other fascinating stuff in it, too. -------------------------------------------------- Note added at 1 day6 hrs (2014-01-09 14:25:38 GMT) -------------------------------------------------- Here's a more modern Sylvania bulb with an offset filament and integrated reflector. http://tinyurl.com/q82x9rc An enlarger bulb (same principle) with a 90° offset filament - it certainly looks "vorgebaut" :-) A Zeiss bulb with an offset filament (scroll down for a diagram) http://tinyurl.com/pl3hho9 https://archive.org/details/journalofsociety19socirich |
