Journal . by operating the delivery valve and the three-way cock,gas under pressure is admitted to the gauger, a rapid delivery isensured, and at the same time the liquid in the side chamberis returned to the tank. 6. As applied to Tank Steamers. The majority of these are equipped with steam pumps placed amidships and fed from the main boilers generally near the stern. The handling of liquid by such means is costly, due chiefly to condensation in the long steam main and loss of pressure. The 106 PNEUMATIC HANDLING OF LIQUIDS. initial cost is great owing to the cost of steam pipes and theirinsulation. The authors apparatus overcomes these difficulties,whilst retaining the general advantages which it procures in landapplication, besides eliminating all loss and danger of fire due toleakage at the pumps. The central battery of pulsators occupiesabout the same space as the pumps. The initial outlay of one ofthese plants compared with steam pumps of similar capacitv isestimated at 40 per cent. Fig. 12. 7. Firing apparatus is equally adaptable afloat or ashore forautomatically supplying oil to liquid fuel burners or feedingDiesel or semi-Diesel engines. 8. Military Supplies. The apparatus which we have described is adaptable to mili-tary requirements, and particularly so for mobile troops. Theconsumption of liquid fuel by various artillery, Air Force andmotor transport formations was considerable during the last war,and it is certain that it will be much greater in the ntxt. It may be said that the capacity for observation and bom-bardment, and rapidity of manoeuvring a modern army dependson the rapidity, activity and regularity with which it is suppliedwith liquid fuel. During the 1914-18 war the French armies were supplied bymeans of metal casks and cans distributed from station storesthrough the intermediary of regulation stations.
