Summary

Description
English: The 'System 24' automated workshop by D.T.N.Williamson - drawing from US Patent 4621410. The patent had a very long, protracted history. The original claim was filed in 1967, and actually built as presented in this drawing by 1969 (at Deptford plant of Molins, Ltd.) - but due to legal disputes with US companies the patent was only issued in 1983, when Williamson already retired.

Public domain The text and illustrations of US patents published before March 1, 1989 are in the public domain unless the patent text contains a specific notice that portions are copyrighted. See 37 CFR 1.71(d), 37 CFR 1.84(s)

The original patent contains no such notice, so its contents are in the public domain. Note: This only applies to images published before March 1, 1989. Patents published after that date are most likely copyrighted, unless in the public domain for another reason, such as {{PD-ineligible}}.
