§ Mr. ALSTEADasked the Civil Lord of the Admiralty whether his attention has been called to the claim of J. M. Campbell, of Cheadle Hulme, Cheshire, to be the inventor of what is known as the blister or bulge protector, as used on His Majesty's warships for protection against submarine attack; and will he take steps to have the claim investigated?
§ Mr. AMMONI would refer the hon. Member to the reply given by the Parliamentary Secretary to the Admiralty on the 28th March, 1923, which was to the effect that the bulges fitted to His Majesty's ships are the result of experiments carried out by the Admiralty prior to the war, and the design adopted does not embody Mr. Campbell's proposals. His claim has been thoroughly investigated by the Admiralty, and the Royal Commission on Awards to Inventors, to whom Mr. Campbell applied, also considered it. The result was that Mr. Campbell failed to substantiate his claim.
