A crane is a crane because of the HOIST function.
It’s a very conventional Anglo-Saxon history!!!Not a true history..The 1st electrical harbor crane operational for testing was in 1892 with 500Vdc (Westinghouse/Edison battle) at Le Havre harbor the patents for balanced cranes, the containers cranes (patent of 1954 sold to Kruppp) are French inventions. Not English or us inventions; Please learn French and interview the good persons.. On History channel it’s the same for many inventions :– like Cathedral with the gothic Ages (Pierre de Montreuil, Abbé Suger)– like radar, (CSF,s patents, Ponte's mission to GEC with the fundamental piece the oxide cathode never found by German and Japanese scientists during the war (not likelike cavity anode structure)– like propulsive helix (F. Sauvage before Smith)– lke French nuclear leadership (letter of Szilard/Einstein after the Joliot's patents, letter from Chadwick to the Royal Society opened 75 years after).History Chanel repeats only the well known stories; it’s not respectful and true.History Chanel learnings and behavior have to change.'Inadvisable to publish' James Chadwick realised the sensitive nature of the documents of the french scientists published 75 years afterThe envelopes contain the work of two French scientists, Hans Von Halban and Lew Kowarski, who worked in the Cavendish laboratory in Cambridge.The documents detail experiments on nuclear fission, covering the components needed to make a nuclear reactor, how to create plutonium from uranium, and methods to stabilise nuclear chain reactions.Dr Brian Cox, a particle physicist from Cern, said: "These papers describe what was cutting-edge science at the time. "The sheer amount of knowledge that these papers contain amazes me – only eight years after Chadwick discovered that a neutron even existed, these scientists are already looking at how to use neutrons to bring about nuclear fission and energy."I can see why these papers were locked away during the war – they contain details that could be used to build a nuclear reactor."The sealed envelopes were accompanied by a letter from Professor Chadwick. Recognising the possible consequences of nuclear fission's massive energy releases, he wrote that the work was "inadvisable to publish at the present time".Dr Cox said: "These papers are a truly significant part of nuclear history. They provide a fascinating insight into the inquisitive nature of scientists working in a field moving so rapidly it was almost outpacing them."It is fascinating to read their views on what might come of their research – and how accurate some of their predictions have been."
