    • X and Y Plane Drivers for WWII Memory 

      Shansky, David (MIT Digital Computer Laboratory, 1953-02-26)
      A number of different schemes are being considered as possible candidates for the circuitry to be employed in the X-Y plane current drivers in WWII. Briefly, they may be classified as to the type of selection mechanism ...

    • X-Ray Equipment for Magnetic Research 

      Tuomi, D.; Vinal, F. E. (Lincoln Laboratory - Division 6, 1954-07-29)
      After an examination of the manner in which x-ray techniques may be applied to a magnetic materials research program, the applications most meaningful to our particular interests have been selected. It is apparent that our ...
