Mr, Halbert said he hoped that means would be devised by which the compound would be mechanically distributed, and the mechanism automatically actuated by the advent of ice-forming conditions.
Imperial Airways flying-boats and other air liners now have their vulnerable parts painted with the compound. It is stated that Capt. Powell, the commander of the Cam-brio, reported, after the last of her recent flights across the Atlantic, that after two hours of blinding rain, the compound remained in sufficient quantity to be efficacious.
In one experiment a wireless aerial not coated with "kill frost" broke under the weight of the ice on it; another aerial, which had been coated, was in no way impaired, The nature of the compound is a secret. The weight sufficient for one Empire flying-boat is about 301b., and the còst works out at about 2s 6d per 1b.
In the United States an ice-breaking contrivance has been officially approved. It consists of a flat rubber tube along the leading edge. The mechanically-induced pulsations of the tube break up the ice.
