Summary edit
| 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. |

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}}. |
