Testing Cores for WWII
(MIT Digital Computer Laboratory, 1953-03-30)
Since approximately one to two tests per second have to be made to test sufficient cores for WWII in thirteen weeks, the present testing technique is unfeasible. Semi-automatic or preferably completely automatic testing ...
Uniformity Tests on Ferrite Cores
(MIT Digital Computer Laboratory, 1952-10-21)
One thousand ferrite cores from General Ceramics, M-1118 (fired 3-9-52), were tested for uniformity of the peak magnitude of the disturbed one. Approximately 25 per cent and 50 per cent of the cores were within ± 5 per ...
