Charles Frederick Goodeve was born on 21 February 1904 in Neepawa, Manitoba. in the autumn of 1927 Charles went to study in at London, England, in University College on a scholarship.While in England, Charles kept up his naval interests through the R.N.V.R. He went to sea in submarines and minesweepers, and served in four battleships and three destroyers. He qualified as a torpedo specialist at Devonport and then specialized on the electrical side. In 1936 he was promoted to the rank of Lieutenant Commander and began to direct his research towards naval problems. For these he obtained Admiralty finance and as a result became acquainted with Admiralty departments and procedures. He did attachments in H.M.S. Vernon, the mining establishment in Portsmouth, and these led to his being appointed there when war broke out in 1939. The Development of Degaussing The Admiralty had already begun fixing ships with copper cables these carried an electrical current which induced an N-pole-up magnetic field to counteract the ship's own N-pole-down field. But there were neither cables nor fitting facilities sufficient to cope with the great numbers of ships that required protection. Warships and the largest merchant ships had priority. Something was desperately needed for the remainder of the ships.Charles came up with the idea that ships could be subjected to a very strong magnetic field in facility such as a wet dock surrounded by an enormous electric coil. The trouble was that the power required and the cost of even one installation would be exceedingly great. Charles saw that the idea of inducing permanent magnetism in a ship was the right one but somehow the current required must be vastly reduced. He then had the idea of passing a horizontal flexible rubber-insulated electric cable up and down a ship's side so as to induce the required permanent magnetism in the ship's plates.Charles performed actual field tests on submarines which were highly successful. By April 1940, ten degaussing stations were operating in Britain; by June about 1000 ships of all kinds had been wiped and many vessels that took part in the Dunkirk evacuation were so protected, thus ensuring their safety in the operation.Charles is also credited with inventing the term 'degaussing', which he named after Karl Friedrich Gauss.After the war Charles received an award of £7500 for his invention, which was the largest individual award made in connection with claims for devices designed to combat magnetic mines. This he generously shared with those who had helped him bring the idea to success. Development of the Hedgehog Antisubmarine Mortar The Hedgehog antisubmarine mortar. The Royal navy had been attempting to develop a weapon to throw antisubmarine charges ahead of a destroyer or corvette. This type of weapon be far deadlier than existing depth charges, which were dropped astern and gave a submarine too much time to escape.Charles drew up plans for a weapon firing a pattern of relatively small contact charges from an array of spigots mounted on the bow of a ship. In the final design there were 24 projectiles in the pattern, each with a charge of 31 lb of explosive they landed in a 130 ft diameter circle 215 yards ahead of the firing vessel. This time it was not complacency that attempted to scuttle the project, but political influences. However, a demonstration of the weapon was arranged for Winston Churchill, and successful sea trials were completed by HMS Westcott against a submerged wreck in Liverpool Bay. The weapon showed it's worth and was adopted by the allied navies. By the end of the war the weapon had accounted for some fifty enemy submarines. Following his outstanding successes in weapon development, Charles was awarded the Order of the British Empire (O.B.E.). At the conclusion of the war in recognition of his great contributions to the allied effort at sea, Charles was created a Knight Bachelor (1946) and awarded the U.S. Medal of Freedom with Silver Palm. see The Secret War 1939 - 1945 by Gerald Pawle From Norman SELLS Tenterden Kent UK ---------------------------------------------------------------------------- 3) From JRKutina@webtv.net (John Kutina) Subject Casting resin parts - RR and ship I live in the Seattle area and I do a lot of casting for my layout as well as small ship parts. The brand I now use is "Smooth-on". It is excellent material and the real dividend is the mix is one to one on both the rubber mold material as well as one to one on the resin material. It is sold in small bottles with about one inch screw tops. This makes it difficult to measure carefully in tiny amounts - I use tiny wax paper milk containers designed to accommodate one teaspoon of milk. They work perfectly. For larger molds I use either condiment plastic cups or regular plastic water glasses. In this area the local brand is "Western Family". They use sturdy plastic bottles to sell their mustard. They use heavy duty plastic squeeze screw caps. All their mustard is packaged that way. A small plastic bottle of mustard is only 95 cents. The commercial squeeze empty bottles sold in drug stores are at least 75 cents and are not as sturdy and the screw caps are easily clogged. By dumping the mustard you get a much sturdier squeeze container. If you are interested in using "Smooth-On" contact me off web site for get more info.
