Standardization of A MOST interesting little Tyres May Create 1-1 booklet entitled "Facts Some Problems. . About ' L ' Tyres" is to hand
from the India Tyre and Rubber Co., Ltd., 30, St. John's Wood Road, London, N.W.8, whence it can be obtained free. Most operators will know that fundamental changes in the size markings of the larger tyres for commercial vehicles are taking place, but many know little of the considerable effect of such changes. It is in the interests of world standardization that the British tyre industry has agreed to adopt new overall dimensions (covering inflated diameter and width) in line with current American and British export practice. This development will be gradual, depending upon production facilities, and, in the case of certain sizes, upon the time required to solve original equipment and replacement interchangeability. problems. The first stage will be the establishment of two separate ranges to replace existing low-pressure and high-pressure giant tyres. Large-dimension tyres to replace the low-presAire will be single-marked, e.g., 7.50-20 with the letter " L " inscribed within a circle adjacent to the tyre size. Such a tyre will replace the existing 7.50-20 H.S. Those substituted for high-pressure tyres will be dual A24 waited, e.g., 7.50-20/34 x 7 with the letter " L " as above, replacing the existing 34 x 7 H.S. Many sizes not easily interchangeable are being issued as original equipment of new vehicles, and it will be necessary for users to exercise exceptional care when ordering new tyres during the transition period.
FROM timeto time we have published brief details of technical reports concerning German industry, from information supplied by the British Intelligence Objectives Sub-committee (B.I.O.S.). Investigations to obtain this valuable information in Germany ceased in June last year. More than 6,000 people took part in them, and 2,700 reports have been issued. Over 1,000,000 copies have been sold or distributed to universities, learned societies, public libraries, etc. In a few months some 50 B.1.0.S. overall reports, to indicate what we have learned from Germany and to compare practices there with the latest British in particular fields, will be published. Those of especial interest to our readers will concern fire-fighting, engineering, road research and road vehicles.
What Our Technicians Have Learned from Germany
rersonal Remarks on WE shall miss Mr. J. Good, the Loss of an Old " 0.B.E., who was for many Friend years with Guy Motors, Ltd.,
although, because of his ill health and the exigencies of the war, we were not able to see much of him recently. He was a charming character, with a deep fund of knowledge and we used to enjoy our meetings at his favourite little restaurant in Soho. A native of Glasgow, he possessed a wide engineering knowledge and was a Whitworth Scholar. During the 1914-18 war' he was Deputy Director of Projectiles. For nearly 20 years he travelled the world, living in Australia for some time, following which he became export manager and London director of Guy Motors, Ltd. When the recent war broke out, he took charge of the Guy Welded Armoured Vehicles Department at Wolverhampton, the welding process proving so successful that it was eventually applied to all types of armoured fighting vehicle for use by the Allies
Two Cases Where THE men at the works of the Increased Pay Was Aero Piston Ring CO., Justified Leeds, will have to look to their laurels. Recently production records have been broken by two women employees. In the past six months they have doubled the output of piston rings processed on the machines they operate, in comparison with the output from the same machines a year or so ago. The increase has not been aided by any changes in the manufacturing process, but is solely the result of the efforts of these two operators, whose remarkable performance was reflected in their high earnings.
