Col. No, what of him? One of the most successful of the two-stroke cycle engines was that designed by Mr G. F. Mort and constructed by the New Engine Company. With four cylinders of 3.69 inches bore by 4.5 inches stroke, and running at 1,250 revolutions per minute, this engine developed 50 brake horse-power; the total weight of the engine was 155 lbs., thus giving a weight of 3.1 lbs. per horse-power. A scavenging pump of the rotary type was employed, driven by means of gearing from the engine crankshaft, and in order to reduce weight to a minimum the vanes were of aluminium.457 This engine was tried on a biplane, and gave very satisfactory results. gray black black He stood still, irresolutely. Her voice and accent struck him with surprise, he recognised them as belonging to a person of a different class from any he had expected. How came such a lady to be alone at that hour, standing in the cold street? At length he said, gently, "If I may advise you, it would be well for you to go home. The person who keeps you waiting in the street in such weather, and at this hour, must surely be very thoughtless. Can I not assist you? I am David Powell, a poor preacher of the Word. You need have no fear of me." 黄色视频网站_亚洲 中文 自拍 另类 French military aeroplane trials took place at Rheims in October, the noteworthy machines being232 Antoinette, Farman, Nieuport, and Deperdussin. The tests showed the Nieuport monoplane with Gnome motor as first in position; the Breguet biplane was second, and the Deperdussin monoplanes third. The first five machines in order of merit were all engined with the Gnome motor. "What next?" I asked, as we could hear the slam of the door in the Wilford apartment. We have, during the seventeen years since aeroplanes first took the air, seen them grow from tentative experimental structures of unknown and unknowable performance to highly scientific products, of which not only the performances (in speed, load-carrying capacity,313 and climb) are known, but of which the precise strength and degree of stability can be forecast with some accuracy on the drawing board. For the rest, with the future lies鈥攁part from some revolutionary change in fundamental design鈥攖he steady development of a now well-tried and well-found engineering structure. Castalia looked almost happy. But she said, "As to her affliction, it seems to me that she has been growing much stronger lately."
