Two views of the Orenco Tourister in flight JUNE 17, 1920 a type which has given very good results in the U.S. mailand army aeroplanes. It is felt that while the 150 h.p. engine has been found to give ample power for ordinarypurposes, it will be an advantage to have the additional power available for flying in mountainous country, and alsofor improving the " take off," although it is claimed that the machine is already very good in this respect. • It has also been found possible to improve the accommoda-tion of the machine which should add considerably to its prospects from a commercial point of view. The front andrear cockpits have been enlarged to permit more freedom to the passengers, while a door fitted to the frontcockpit allows of easier access to the interior for the pas- sengers. Another alteration, which, if it is not altogetheran improvement certainly, adds to the attractiveness of the machine, is the employment of a mahogany veneer fuselagevThe main specifications of the " Orenco " Type F are :— Span (both planes) .. ., 38 ft.Chord .. 5 ft.

Aviation HelmetsTHE Royal Commission on Awards to Inventors on Monday heard a claim by Mr. Charles Henry Curtis, a tailor,trading as Messrs. George Curtis and Co., of Grafton Street, in respect of an aviation helmet, which he said was hisinvention. Mr. T. Carthew, counsel for the claimant, explained thathis client first took up the question of head protection for aviators in 1913, and in 1916 one of his helmets was adopted as a field pattern by the Royal Army Clothing Departmentfor aviation purposes. Mr. Curtis had made a claim of 5s. royalty on each helmet, and the Ministry of Munitions hadoffered him £100. Maj. Lewis Turner, formerly an instructor in the RoyalAir Force, stated he considered the helmet the best in use and superior to the " Roold." For the Ministry of Munitions, Col. W. D. Beattie, of theCivil Aviation Department, said that for all-round purposes they had found that the " Roold " helmet was superior to thehelmet invented by the applicant. It was lighter, not so hot, and probably gave equal protection. Mr. Trevor Watson, for the Crown, said the " Roold "helmet was the invention of a Frenchman, and it was because of the difficulties in supply that the Department was com-pelled to fall back on Mr. Curtis's pattern. The Commission will announce their award. 648
