Inventions and Official Secrecy - O'Dell, T. H. (Electronics Engineer (Retired) a Emeritus Reader, Electronics Engineer (Retired) a Emeritus Reader, Imperial College, London)
Inventions and Official Secrecy traces the little known history of legislation which permits the British Government to prohibit the publication of certain technical ideas submitted as patent applications. The story begins in 1855, with the first recorded case of prohibition, and ends, as the thirty year rule demands, in the 1960s.
