A " Safety " Newspaper For Training
the Young . . .
ANillustrated newspaper for children, which deals with aspects of safety in a popular style, has been produced by the National "Safety First" Association, under the title of "The Green Light." It is offered to educational authorities for distribution in schools, and the L.C.C. alone has ordered 100,000 copies. This little paper, which should certainly be attractive to all children, may be obtained at 2d., including postage Technical Press Repp EFERRING to the Techniceives Some Words I • cal Press at the Blackpool of Praise . . . . dinner of the P.S.T.A., the chairman, Mr. T. E. Thomas, general manager (operation). L.P.T.B., said:— " Follow our leaders in the Technical Press. It is their duty to bestow praise when it is due and say when it is not; to drag our light from beneath the A30 obscuring bushel; to make men of us, and, incidentally, to improve their circulation.; in the process." So long as the former is true, we accept the soft impeachment implied by the latter, and thank Mr. Thomas for his encouraging remarks.
Is Faulty Vision 1)1■11 ECENT tests carried out Responsible for Many by the British Sight
Accidents / Efficiency Committee,
appointed by the optical industry to investigate standards of vision, have brought vitally interesting results. At a recent London exhibition, the tests were carried out on a large cross-section of the public, and revealed that over 48 per cent, were suffering from visual defects unknown to them and, therefore, neglected. A large number of those who participated are drivers. The Committee believes that this neglect may be a root cause of many Otherwise inexplicable accidents on the road.
REFERENCF. has already I %been made to the fact that the Ministry of Transport has notified the taxation authorities that, when a vehicle is found to be above the weight for its category, opportunity should he given for it to be cleaned, dried and reweighed before any higher tax is demanded. The National Federation of Grocers' and Provision Dealers' Associations has, in view of this decision, asked that a refund should be granted where vehicles now passed as correct have been charged additional taxation retrospectively over a period of a year or more. The Minister has agreed that, if particulars of specific cases which have occurred within the past. 12 months be submitted, he will take up the matter with the authorities concerned.
Where Re-weighed Vehicles Have Paid Higher Tures . . . New Rayon Tyres rri ENASCO is a new class of Are Stronger Than I high-tenacity yarn, made Cotton by CourtauIds, which has been used extensively in cords for pneumatic tyres, but can be utilized for" other pur poses. The tenacity is considerably higher than normal and the extensibility can be suited to the purpose for which it is required. The type A has a practically straight stress-strain diagram, and it shows great superiority in recovery over ordinary rayons. The high elasticity and low extensibility prevent gradual enlargement or "creep," due to plastic deformation. One important advantage is that drying by running temperatures increases the strength of Tenasco A, whilst reducing that of cotton, less internal heat is developed, and the difference in strength is 32 per cent. in its favour.
