7. MRC Intellectual Property MEMO to D. P. Wahl from Edberg, 1968 January 8
Describes the sole U. S. Patent granted at that time (E. F. Lindquist), and a list of nine patents pending, six technical disclosures, and seven Technical Development categories and "know how". Many of the items listed led to U. S. Patents being granted in future years

10. Original Folder: "SCAN HEAD SYSTEM for Sensing Marks and/or Punches from Cards: MRC Model 1501 Card/OMR Reader" B.S. & B file 15,318. Contains JVM's original 46-page Technical Disclosure [MRC R/D Dept.], ten technical drawings, Edberg to/from Beveridge Correspondence file (Chief Engineer to MRC Patent Attorney), and related documents, 1966 March 12
11. TECHNICAL DISCLOSURE on COLUMN SYNCHRONIZATION METHOD for OPTICALLY SCANNED DOCUMENTS developed by the MRC Product Development Dept., authored by John V. McMillin, Manager, 1966 October 31
This 30-page document, plus APPENDICES with drawings, tables, charts, and related information, describes an early use of solid-state technology and related mechanisms to solve a timing issue with the high speed combined OMR/punched-hole reading of IBM 'tab card' documents on specially designed MRC scanners
12. MRC Technical Report: TENTATIVE SPECIFICATIONS FOR MRC SCORING MACHINE TAPE OUTPUT SYSTEM, 1961 April 25
4-page report, plus tables, block-diagram, authored by JVM, and trip report to DI/AN Controls vendor. By the early 1960's, magnetic tape systems were becoming available to replace/supplement the ubiquitous punched-hole IBM tab-cards for storage. Accordingly, MRC began plans to store the scanned OMR sheet output data onto magnetic tape. This brief technical report outlines the requirements, steps, procedures, and includes a JVM Trip Report summarizing several possible vendors to assist MRC in accomplishing this objective. Authored by JVM. In due course, MRC did indeed convert to magnetic tape storage systems, rather than cards
13. E. F. Lindquist MEMORANDUM to Bob Edberg (Chief Engineer) describing his latest developments in High Speed Precision Sheet Feeder for Mod 9 (scoring machine), 1965 July 29
Includes 4 hand-drawn sketches, by Lindquist, initialed and dated 27 JUL 1965. His memo copied to John McMillin (Project Engineer), Tom Jacob (MRC engineer), and Pete Wahl (General Manager). A rare document that exhibits Dr. Lindquist's creative mechanical-design abilities and draftsmanship!
14. E. F. Lindquist's document, MULTIPLE SENSING AND SWITCHABLE ENCODING IN OPTICAL SCANNERS, "An Invention by E. F. Lindquist", 1965 August 2
Yet another example of Dr. Lindquist's passion for clever inventions and being deeply involved in the 'early days' of MRC Engineering development and design of OMR scanners. True, we on the MRC engineering staff sometimes regarded Lin's ideas as a bit on the Rube Goldberg side of the aisle, and as I recall, this was one of them, and we never implemented this particular idea of his, nor did he apply for a patent. However, this original Lindquist paper does describe a basic and fundamental problem - with respect to document registration - in the accurate scanning of position-encoded OMR marks therein, and fortunately, the problem was solved more than a decade later when CCD arrays became commercially available. Refer to McMillin/Schroeder U. S. Patent No. 4,300,123, issued 10 NOV 1981
15. LAMENT OF THE BUBBLER: a doggerel by Buz Spooner, Principal, Greenacres Elementary
Not everyone, in fact most students, did not enjoy "filling in the answer-bubbles" on the Lindquist Iowa Tests of Basic Skills battery of tests. Apparently, Mr. Spooner sensed this frustration amongst his students, and wrote this witty and humorous poem. Although the enclosed copy is not dates, I believe it began to circulate in the 1960's, and no doubt has withstood the test of time!
