19. OUTPUT STACKER for HIGH SPEED DOCUMENT CARRIERS: Inventor: E. F. LINDQUIST, 1967 January 30

Scope and Contents

This 11-page Technical Disclosure is 'classic Lindquistian' in terms of elaborate mechanical components, such as springs, rollers, plates, plastic sheets, foam rubber, and related apparatus. The Disclosure includes four original 11" x 17" Figures/Drawings, signed by RAE (Robert A. Edberg, Chief Engineer at MRC), and dated from 28 to 31 JAN 67. The descriptive Figures were probably drafted/drawn by Edberg, as they are rather 'too neat' with respect to Lindquist's more informal/cryptic style of sketches normally seen with his Technical Disclosures. My copy of this Lindquist Technical Disclosure contains a cover letter written by Edberg to the MRC Patent Attorney, Mr. Andrew B. Beveridge, dated February 1, 1967, requesting a review of the attached material for patentability (e.g. conduct a prior-art patent search, etc.). Curiously, however, the Edberg letter states that "This will be a personal patent by E. F. Lindquist and consequently you will bill him directly for the work involved." Furthermore, in Edberg's handwriting on the top of the letter is the notation "Not mailed at EFL's request - Edberg", so Lindquist must have had second thoughts. I was not directly involved in this 'elaborate Lindquistian' design to effect a gentle deceleration of the scanned sheets as they were driven into the output stacker at high speeds, so I can only speculate that possibly Lindquist saw a potential opportunity to profit from owning the anticipated U. S. Patent himself, and to license the idea to other companies who had similar problems with gently stopping sheets of paper moving at high velocities. Regardless, we did not incorporate this complex design into our MRC high-speed OMR scanners of this era, but solved the deceleration by more simple means
