Altered new, public-service vehicles are,

in some cases, being asked by licence holders to make alterations in the war-time bus-body specification whiCh was agreed between the Ministries concerned, the operators and the bodybuilding industry. The main idea was to conserve labour and material and, 'h.s licences to acquire apply only to approved designs, any changes made are fraught with danger, not only to the bodybuilders, but also to any operators who persist in making this endeavour.

A CCORDING to a recent r-report from America, a method has been devised for sealing tyre outer covers to the wheel rims and inflating them without the use of inner tubes, thus saving the rubber which would have 'been used in the tubes. After many car owners 'in the town of Tulsa, U.S.A., had tested the method, the city authorities followed suit, and all its vehicles having wheels ivith drop-centre rims are now tubeless, whilst the Douglas aircraft factory in the same town is also adopting the new method. First the rim is cleaned and smoothed, then a valve (preferably :oversize) is .fitted into the opening and secured with a locknnt and rubber washer; all irregularities, . especially in the beads, are sand-papered smooth.

A Novel Method of Using Outer Covers Without Tubes

The casing is ,then mounted, blown up rapidly, and tapped at the same time to ensure that the beads seat themselves evenly. A water-immersion test then follows. Sometimes, to seal small cracks and • inequalities, it is necessary to inject a pint or so -r;fliquid cement.

Engineer Advises on A T the a.g.m. of R. A.

Methods of Post-war I–I Lister and Co., Ltd., the Planning chairman made some cogent remarks concerning preparations for the future. He said he felt that the time had come when, without impairing the -war efforts of their firms or industry, those able to make their contributions to the post-war planning of their individual industries should do so. Just as governments will travel() think and plan internationally if a peace worthy of the sacrifices made is to be our reward, so those in industries must think and plan nationally if post-war production is to ,provide maximum employment and ensure the most efficient use of British labour, materials and money. A treater measure of co-ordinated effort in industry will be pecessary if domestic and overseas consumers are to obtain the real benefits of the latest and-best mass. production methods. Manufacturers must get together and increase the chances •of sound international understanding among competing industries facing common problems in the export markets.
