Why Demand Good WAR and waste appear to be Finish on Our War I" synonymous terms but in
Vehicles ? . . connection with the production of lorries for war work, it seems appalling waste for a superfine finish to be called for, including highly polished woodwork and fine painting, which is minutely examined for defects of finish. Following this, vehicles are often gasproofed, which roughens the surfaces, and they are usually repainted in camouflage colours.
Avoiding Damage to IVIANY are the uses of radio Underground Pipes lsignalling devices. One of When Excavating . . the most novel is what is
known as the pipe anticipator (of no particular interest to smokers), which can be attached to any type of mechanical excavating machine. It warns operators by audible signal of the presence of metal pipes, cables, etc., buried beneath the surface, functions equally well in all classes of soil, dry or wet, and is effective whatever the size of a pipe or the depth at which it is buried, whilst 106 being immune from electrical interference. The set includes an oscillator, control equipment, amplifier and earphone. The action depends upon the impedance of the intervening soil, the signal volume being inversely proportional to the square oE the impedance.
Preserving t he IF a vehicle is to be laid up Battery While the I for some time, unless the Vehicle is die . . battery be an expensive one, the cost of maintaining it in condition may not be justified. It may be more economical, in the end, to dispose of it and buy a, new one later. If new or expensive, however, the battery may be coupled up to a rectifier, and given a freshening charge at least every two months. Trickle charging is permissible up to six to eight months. In Some cases a local garage will assume responsibility for maintenance at a reasonable figure, but in every case the battery should be fully charged as a start. Protection should be given to avoid the risk of the electrolyte freezing. Save and Sell Your CIONSERVATION of our Scrap Iron and ‘-'supplies of iron and steel is Steel extremely important. About half the total weight of materials charged into British steel furnaces consists of scrap. Thus, in 1937, about 7,500,000 tons of scrap were melted in producing 13,000,000 tons of steel ingots. Therefore, as much home material as possible should be salvaged, even from sources not so thoroughly tapped in ordinary circumstances. This wifil relieve our dependence upon imports and effect considerable economy. Eight-wheelers A PPARENTLY, the pro Laden with Britishduction of crude oil in this produced Oil . . country is slowly progressing. The other day one of our observers saw two Scanunell eight-wheeled tankers, each carrying 3,000 gallons, which had come from one of the new wells. This well is 1,900 ft. deep and is delivering 700 gallons per hour. The crude is quite black and rather thick, but the warmth of the hand is sufficient to make it run almost as easily as paraffin. The vehicles were proceeding to the Anglo-Scottish refinery.
