Letter written by E. F. Lindquist to the MRC Law firm in Washington, D. C. that handled all MRC applications for U. S. Patents, based upon Lindquist's, McMillin's, and other MRC staff members' inventions. The EFL letter included a 3-page technical description, dated 8/3/65. This invention, as described in Lindquist's letter, covers a concept for automatic detection of an OMR sheet side-registration position during scanning, and secondly, correcting/adjusting for any detected side-shift errors. Case File No. 14,173. The original R/D investigation/conceptualizing activity began July 14, 1965 (see the cross-reference shown earlier in this list) by Lindquist and McMillin: refer to my 16-page handwritten document, dated 7-14-65, including drawings and sketches, also attached. The same document contains witness signatures dated 15 July 1965 by George E. Carsner, and Thomas B. Jacob, MRC Engineers, with the notation "Invented by E. F. Lindquist and John V. McMillin"
