Bodleian Archives & Manuscripts (new; for the Marconi archives and GEC/Hirst material)

URL: https://archives.bodleian.ox.ac.uk/search. Scripted access got an Anubis proof-of-work page. In Chrome, the Anubis check passed by itself after about a minute (it is not a CAPTCHA). Results were read from screenshots, because the extension may not read text on this domain. Queries: Ternion (26 hits, all stemmed to "terns": birds), Kassner, Bauch (0), "Universal Inventions" (0). Finding [web]: MS. S.P.S.L. 508/1-4, "W Kaeser - E Kassner", 671 leaves, Archive of the Society for the Protection of Science and Learning, series "Files of correspondence relating to individual refugees who were not funded by, or registered with, the Society". The SPSL helped scholars displaced from Germany after 1933. A file on an "E Kassner" fits a German engineer in London in 1934-36, but the catalogue does not say which E. Kassner. Next: ask the Bodleian (Special Collections) whether the E Kassner file concerns Ernst E. W. Kassner and what it contains. Marconi: no Kassner, Ternion or Bauch entry in the catalogue descriptions. Bauch's 1934-35 "radiation therapy" sale to Marconi is not catalogued at this level. Result: partial.

USPTO image server (recheck; positive in run 1)

Retrieved by number: US 2,415,025 (Grell and Richards, assigned to Firestone and Goodrich; 9 pp.) and US 2,495,429 (Spencer, Raytheon; 3 pp.). PDFs and tesseract OCR in files/ (US2415025.pdf/.ocr.txt, US2495429.pdf/.ocr.txt).

F. Goodrich Company" [web: https://image-ppubs.uspto.gov/dirsearch-public/print/downloadPdf/2495429 ; .../2415025]. Result: positive.

Caselaw Access Project and CourtListener (recheck)

CourtListener search API (no login): "2,089,966" gives Arnold v. Watson, In re Arnold (known) and Fuller v. Commissioner, 37 T.C. 147 (1961). The Fuller opinion (from static.case.law) has no patent reference; the number there is not the patent, so it is not relevant and the downloaded copy was deleted. Kassner "dipolar" gives In re Arnold only. "Industry Inventions" gives 0. "Giodvad Grell" gives Grell v. Insurance Co. of North America, 274 A.D. 760 and 762 (N.Y. App. Div., 7 Jun 1948): a New York insurance suit by Grell, not read; a lead on Grell's affairs only. Vibranic gives fuzzy matches only. Further calls were rate limited (5/min). Result: partial (no new case on the claims).

Espacenet (retry of a run 1 block)

In Chrome, Cloudflare showed "Verify you are human" (an interactive challenge). Per instructions it was not attempted. Blocked (CAPTCHA). Google Patents now supplies most of what was wanted (families, citations), but not the text of GB448418, GB435643 or FR786294.

HathiTrust full-text search (retry of a run 1 block)

Search works in Chrome. "Ternion A.-G." gives 39 items, all of kinds already known: Ellis Chemistry of Synthetic Resins, Weissberger Technique of Organic Chemistry, Thorpe, Rubber World 1935, Official Gazette 1934, Index of Patents 1934, Chemical Abstracts v.29 1935, Wireless Engineer and Electronic Technology 1936, plus Science et industries photographiques 1936 and Photographic Abstracts (probably the GB 435,643 light relay). Kassner Ultrakurzwellen (all words) gives 100 items. Leads among them: Hochfrequenztechnik und Elektroakustik (several volumes), Der Balneologe (a physical-therapy journal), and the 1944 Bücherverzeichnis, Bücherei des Flugfunk-Forschungsinstituts Oberpfaffenhofen (the library catalogue of the German aviation-radio research institute; HathiTrust id uc1.$b560612). These are limited (search-only) items. The "search inside" page did not render in the browser, so it is not known whether the hits are E. E. W. Kassner. Result: partial. Next: search inside uc1.$b560612, umn.31951002733267b (Der Balneologe) and the Hochfrequenztechnik volumes (mdp.39015082273890, nyp.33433109987119, mdp.39015013786713) for "Kassner".

US National Archives Catalog (new)

"Ernst Kassner": 2 hits (a 1924 New York passenger-list index; captured German records, "Number 518", in the National Archives Collection of Foreign Records Seized; not opened).

The matching lines are not exposed by the search, so the context is unknown. Vibranic 0. "General Infra" 7 (unrelated). "Industry Inventions" and "Dipol A.G." were not completed. Ternion gives 183 OCR-noise hits. Result: partial. Next: open NAIDs 88008358, 222879108 and 401666746 and read the digitised pages.
