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. |
