A PRINTER'S error crept into the announcement of the Automatic Telegraph Co. in our last issue, the word lever being substituted for the word" telegraph," in describing their very ingenious '' one lever " automatic telegraph for aircraft. It may be recalled that this compact little instru- ment enables a large number of messages to be sent out automatically by wireless by simply depressing a lever; there is no need lor the pilot to know anything about wireless and he has not a transmitting key to operate. Full particulars can be obtained from the firm at 132, Charing Cross Road, W.C.2. THE factoring business formerly carried on by Messrs. Mestre and Blatge at 20, Store Stree't, Tottenham Court Road, W.C., having been taken over by Ewen, Ltd., of Salisbury, the former firm will not trade as factors but will specialise in the sole control of individual articles in this country. This part of the business has been renamed The Patent Motor Products Co., and Mr. J. W. Hawkes will continue to manage the new business at the old address. As in the past the company will buy British goods required by the Paris house as well as its continental and South American branches. Amongst the specialities handled are : " Magic " tyre repairer; L'Hermetical jointing solution ; Gobbi carburettor ; and the Van Sicklen speedometer. THE use of drawn or extruded sections in place of labori- ously fashioned bar or strip is too widely recognised to need advocacy. Aluminium as a material for such sections finds many openings by reason of its 60 per cent, weight economy and low first cost, as well as its rustlessness and effective appearance. The range of aluminium sections for which the British Aluminium Co., Ltd., have tools is so large and so continuously increasing that they find it impracticable to issue the exhaustive list for which they are frequently asked. They have, however, added to their series of " Hints on^Working Aluminium " a booklet giving illustrations and sizes of a few representative shapes, and any reader can obtain a copy by writing to the firm at 109, Queen Victoria Street, E.C.4. As producers of the metal, they are always pleased to study special requirements, and in the event of a standard section not proving suitable to manufacture the requisite shape. H H H H Aircraft Darts and Bombsi THE Royal Commission on Awards to Inventors, Mr. Justice Sargant presiding, on November 29, considered claims made by Wing-Commander F. Ranken in respect of four inventions relating to aircraft armament—the Ranken dart, the Baby incendiary bomb, the spe6ial operations pistol, and the relay tube. Appearing for the claimant, Lord Tiverton said that at the time of the invention of the dart and the bomb, Wing-Com- mander Ranken was an officer in the Royal Navy and in H.M.S. " Lurcher " at Harwich. The dart was intended to be projected from an aeroplane into a Zeppelin and to set fire to the inside. For a time it was taken up by the Admiralty until Lieut. Robinson brought down a German airship at Cuffley. On April i, 1916, a Zeppelin, L. 15, was brought down by a dart in the Thames estuary. As to the Baby incendiary bomb, of which a Handley Page could take up 4,000, Lord Tiverton said that in six weeks we dropped over 85,000 of these bombs over German industrial towns, and a considerable number of fires were caused. There were other uses to which the bombs could be put. The special operations pistol was intended to give increased safety in attacking Zeebrugge Dock gates from the air, but the attack did not end in success, as the aeroplane was so vigorously attacked by the Germans. The relay tube was a useful invention. The amount expended on the dart was /5L323 ; on the Baby bomb, ^325,400 ; on the pistol, £685 ; and on the relay tubes, 245.604. Evidence was given in camera as to the use to which the Baby bombs could be put in the future. Mr. Trevor "Watson, for the Treasury, contended that the dart was not a weapon of proved utility, although it was of use at the time. In regard to the relay tube and the pistol, what Commander Ranken did was part of his duty as an officer. The incendiary bomb was an invention of consider- able importance, and the only difficulty was how far it was invented as part of Commander Ranken's duty. The decision will be promulgated later.
