A Graphic Method of HE means• adopted by the Comparing Modern 1 Dunlop company, to call
Perils attention in a dramatic way to
the vehicle operator's need for ty'res on which he can depend is striking and novel. 'Nicie modern perils are being illustrated, these covering a faulty brake, cracked ice, broken ladder rung, weak goods-train coupling, naked light in a mine, defective crane chain, damaged railway line, frayed rope for a climber and a faulty air tube for a deepsea diver: Some of these possible dangers affect only a few individuals, but tyres are employed universally.
One Advantage of IN a recent reporfon the weigh: .Being Weighed for ling of heavy motor vehicles, Excess .Loading....Durham County Council deals with 115 examples. Of these, 99 were found to be correctly loaded, nine slightly over-leaded, which called for cautions, whilst seven cases of serious overloading were reported and may involve legal proceedings. A 'large proportion had not been weighed before proceeding on their journeys, and in one case a haulier was surprised to find that his vehicle was carrying 8 tons 5 cwt. of oranges from Hull to NoWcastle, whilst he was being 'paid for carrying only-7 tons, as represented by the consignor.''' The Certificate given would substantiate his claim for carrying the additional 25 cit.

THE question whether drivers of heavy road. vehicles are skilled workers has been fought out in Germany. Drivers contended that as they had to pass a specialized examination in driving and elements of lorry mechanism they are entitled to skilled workers' rate of pay so soon as they become certificated. The courts decided, however, that, although a definite degree of skill, plus responsibility, is required of heavy-vehicle drivers, that degree does "not yet" entitle them to claim pay equal to skilled tradesmen.

A Ford -eniined nES1GNED and built by an Amphibian for Use L'oil company for working•
In Swamps . . in swamps, a curious machine
called the Marsh Buggy has been developed, with a Ford II-8 engine as its power 'unit. The vehicle has an overall length of 22-1 ft., 'and the enormous pneumatic tyres, which are 10 ft. in diameter and 3 ft. thick, enable the machine to run on land of float on water. The front wheels are chain driven from the back-axle sprockets. The brakes are arranged so that the wheels at each side can be controlled independently, thiS System being ufili2:ed for steering the vehicle when it is' afloat. The wheels, chassis members and platform are Tnade .of,alurninitun and the speed on water is six knots. The Production of THE U.R.S.S. is rapidly Synthetic Rubber in 1 forging ahead with its
Russia manufacture of synthe ti rubber, and the production of 40,000 tons, arranged for the past year, was exceeded by 5,000 tons. The capacity of the works has almost doubled in two years. The total consumption of rubber for 1936 was estimated at nearly 80,000 tons.
THE chief change in engine design is a trend towards higher compression ratios, which is all to the good, but means that petrol has to work under much more severe conditions. This fuel consists of atoms of hydrogen and carbon combined in certain fixed ways. In ordinary petrol these atoms can take the form of long chains and are then susceptible to detonation,
An Interesting Shell Process to Improve Petrol because the oxygen atoms from the air can combine too easily and irregularly with the others.
The problem has been to find some way of controlling the combination of the atoms, and Shell-Mex and RP., Ltd., has solved this with a process called "re-forming," by which the molecular structure of the petrol can be rearranged so that the atoms stay together in compact masses.
How Railways InIN connection with the fixing central sales system, this will
be unnecessary in the whole of the South Yorkshire area, where the railways will not permit the road delivery of coal to customers over a distance exceeding seven miles. They buy their locomotive coal in this area, and use this fact as a lever. '
