Findings (all [web])

  1. The 1945 announcement reached far more of the trade press than run 1 found. It appears in Business Week (10 Feb 1945, p.53), The Rubber Age (Feb 1945), Automotive and Aviation Industries (15 Feb 1945), Automotive News (19 Feb 1945), Coal Age (Mar 1945), Power Plant Engineering (Mar 1945), Fleet Owner (Apr 1945), Rock Products (May 1945), Plastics, Ordnance (Sep-Oct 1945) and The Magazine of Wall Street (26 Oct 1946). All repeat one press release naming "R. A. Dufour and H. A. Leduc of France, and ... E. E. W. Kassner of Switzerland". The added details: - Business Week: Leduc and Dufour's research, "dating back to 1920, was underwritten by the French government" [web: https://archive.org/details/sim_business-week_1945-02-10_806]. - Ordnance (the US Army Ordnance Association journal) gives the heating account: "high-frequency oscillations shake the molecules of rubber and sulphur millions of times a second, creating uniform heat" [web: https://archive.org/details/sim_ordnance_september-october-1945_29_152]. None of them names a patent number or the seller.
  2. Industry Inventions, Inc. This is the licensing company for the 1945 patents and a new corporate record to trace. - Incorporation papers were filed in Aug 1945 for an Ohio corporation "jointly organized by the B. F. Goodrich Co. and the Firestone Tire & Rubber Co., to handle the licensing of rubber and other firms under the Leduc and Dufour high frequency electronic vulcanization patents" [web: The Rubber Age, Aug 1945, https://archive.org/details/sim_elastomerics_1945-08_57_5]. Officers: W. F. Avery (Goodrich), chairman; W. A. Fraser (Firestone), president; V. L. Smithers (Smithers Laboratories, Akron), vice-president and general manager; H. S. Woodruff (Goodrich), secretary; E. H. Schulenberg (Firestone), treasurer; M. J. Moyer, assistant secretary [web: Chemical Week, Sep 1945, https://archive.org/details/sim_chemical-week_1945-09_57_3]. - The company is also listed in the Akron City Directory 1946 (2706 1st-Central Tower) and in Who's Who entries for its later general manager (1950s-70s). It appears in a 1955 Congressional hearing table beside Firestone (context not read) [web: https://archive.org/details/sim_united-states-congress-hearings-prints-and-reports_july-19-january-3-1956_5_2800-2974]. - Note: the August 1945 licensing descriptions name only "Leduc and Dufour" patents; the January announcement had also named Kassner. Why Kassner dropped out of the licensing description is not explained in the sources. - Smithers's Oct 1945 talk to the Chicago Rubber Group gave the benefits as "saving in time, greater uniformity of products, and better products with better physical properties" (foam mattress cure 30 → 5 min) [web: Rubber World, Nov 1945, https://archive.org/details/sim_rubber-world_1945-11-01_113_2]. This is the buyer's characterization (an interested party).
  3. The 1951 Index of Patents entry "Vibranic Ltd., assignee: See — Kassner, Ernst E. W." is confirmed. The adjacent "Sterilizing canned foods 2,569,645" belongs to G. K. Viall (Chain Belt Co.), not Vibranic. This was checked to avoid a false lead [web: https://archive.org/details/indexofpatentsis1951unit].
  4. Kassner's 1937 US patent 2,096,459 is listed in Radio Daily (Oct-Dec 1937), "Ernst E. W. Kassner, London, England" [web: https://archive.org/details/radiodailyoctdec02unse].
  5. Negative or noise: "Alfred Wiegner" (four unrelated hits), "Wilma Hencke" (0), "Universal Inventions Limited" (only the 1938 patent index), "General Infra"/"Suisse Infra" (noise; no Proclaimed List entry found in the OCR), "Kassner" FIAT/BIOS (noise: other Kassners), "Ternion" G.E.C. and "Kassner" "Hirst" (noise). Orlan M. Arnold: 74 hits on his Chrysler, Rensselaer and Rockefeller career (chemist, Chrysler research), including a 1952 Metal Finishing process; none was read in depth.

How this bears on the claims

Claim / question Effect
7 Of the buyers' public statements, only the January 1945 release names Kassner. The joint licensing company's later descriptions name only Leduc and Dufour. The heating description is the buyers' (interested party). Business Week adds the French state funding of Leduc and Dufour.
Open question: who sold what Industry Inventions, Inc. (Ohio, Aug 1945) is the licensing holder. Its records, and Goodrich's and Firestone's, are the place to look for the patent schedule.
