Belfast interest: Inventions: A manuscript copybook containing technical details of a considerable number of patents, mainly in electrical engineering, with circuit diagrams, details of patent approvals etc., apparently written up by Major Rupert Stanley at the Municipal College of Technology, Belfast, about 1913-14. Inscribed in another hand on front cover, 'Given to me by Major Stanley 26-9-52'
It appears these are not Maj. Stanley's own patents?, rather they are accounts of important patents granted to such inventors as J.A. Fleming etc. With two related typescript letters loosely inserted. As a m/ss. Interesting item. (1)
