Diamond did not choose to discuss either the husband or the wife with young Ingleby, but he said to himself, as he pursued his homeward way, that Mrs. Errington's manner had been not only disagreeable but very strange. � Ader鈥檚 work is negative proof of the value of such experiments as Lilienthal, Pilcher, Chanute, and Montgomery conducted; these four set to work to master the eccentricities of the air before attempting to use it as a supporting medium for continuous flight under power; Ader attacked the problem from the other end; like many other experimenters he regarded the air as a stable fluid capable of giving such support to his machine as still water might give to a fish, and he reckoned that he had only to produce the machine in127 order to achieve flight. The wrecked 鈥楢vion鈥?and the refusal of the French War Ministry to grant any more funds for further experiment are sufficient evidence of the need for working along the lines taken by the pioneers of gliding rather than on those which Ader himself adopted. THE PANDOURS. Except the Digamma, papa! It was owing to the incapacity鈥攁pparent or real鈥攐f the British military or naval designers to produce a satisfactory rigid airship that the 鈥楴.S.鈥?airship was evolved. The first of this type was produced in 1916, and on her trials she was voted an unqualified success, in consequence of which the building of several more was pushed on. The envelope, of 360,000 cubic feet capacity, was made on the Astra-Torres principle of three lobes, giving a trefoil section. The ship carried four fins, to three of which the elevator and rudder flaps were attached; petrol tanks were placed inside the envelope, under which was rigged a long covered-in car, built up of a light steel tubular framework 35 feet in length. The forward portion was covered with duralumin sheeting, an aluminium alloy which, unlike aluminium itself, is not affected by the action of sea air365 and water, and the remainder with fabric laced to the framework. Windows and port-holes were provided to give light to the crew, and the controls and navigating instruments were placed forward, with the sleeping accommodation aft. The engines were mounted in a power unit structure, separate from the car and connected by wooden gangways supported by wire cables. A complete electrical installation of two dynamos and batteries for lights, signalling lamps, wireless, telephones, etc., was carried, and the motive power consisted of either two 250 horse-power Rolls-Royce engines or two 240 horse-power Fiat engines. The principal dimensions of this type are length 262 feet, horizontal diameter 56 feet 9 inches, vertical diameter 69 feet 3 inches. The gross lift is 24,300 lbs. and the disposable lift without crew, petrol, oil, and ballast 8,500 lbs. The normal crew carried for patrol work was ten officers and men. This type holds the record of 101 hours continuous flight on patrol duty. 开心激情五月天_日日色人格_哥哥太坏谁之过_99热这里只有是精品5 THE STORY OF HER FATHER She did not answer, but continued to cry convulsively, rocking herself to and fro. It may thus be seen that the two-stroke cycle type got as far as actual experiment in air work, and that with considerable success. So far, however, the greater reliability of the four-stroke cycle has rendered it practically the only aircraft engine, and the two-stroke has yet some way to travel before it becomes a formidable competitor, in spite of its admitted theoretical and questioned practical advantages. � Frederick dispatched messengers to Ohlau to summon the force there to his aid; the messengers were all captured. The Prussians were now in a deplorable condition. The roads were encumbered and rendered almost impassable by the drifted snow. The army was cut off from its supplies, and had provisions on hand but for a single day. Both parties alike plundered the poor inhabitants of their cattle, sheep, and grain. Every thing that could burn was seized for their camp-fires. We speak of the carnage of the battle-field, and often forget the misery which is almost invariably brought upon the helpless inhabitants of the region through which the armies move. The schoolmaster of Mollwitz, a kind, simple-hearted, accurate old gentleman, wrote an account of the scenes he witnessed. Under date of Mollwitz, Sunday, April 9, he writes:
