7th December CHAPTER XXV. THE DIVISION OF PUNISHMENTS. Certain American radial engines were made previous to 1914, the principal being the Albatross six-cylinder engines of 50 and 100 horse-powers. Of these the smaller size was air-cooled, with cylinders of 4鈥? inches bore and 5 inches stroke, developing the rated power at 1,230 revolutions per minute, with a weight of about 5 lbs. per horse-power. The 100 horse-power size had cylinders of 5鈥? inches bore, developing its rated power at 1,230 revolutions per minute, and weighing only 2鈥?5 lbs. per horse-power. This engine was markedly similar to the six-cylindered Anzani, having all the valves mechanically operated, and with auxiliary exhaust ports at the bottoms of the cylinders, overrun by long pistons. These Albatross engines had their cylinders arranged in two groups of three, with each427 group of three pistons operating on one of two crank pins, each 180 degrees apart. 美国黄色在线一级片高清完整版 免费在线观看 -电影-在线观看 - 综合伊人网 The road goes on. Trees cast their shade on the flagstone pavement, but between the houses and through open windows the sandy plain may be seen, the endless whiteness lost in a horizon of dust. I thought you might be at church, said Diamond, seating himself on the opposite side of the bay-window, and within its recess, "so I asked the maid to get me the book I wanted. But she sent me upstairs." belonged to somebody now, and it's a very comfortable sensation. Attempts at flight on the helicopter principle consist in the work of De la Landelle and others already mentioned. The possibility of flight by this method is modified by a very definite disadvantage of which lovers of the helicopter seem to take little account. It is always claimed for a machine of this type that it possesses great advantages both in rising and in landing, since, if it were effective, it would obviously be able to86 rise from and alight on any ground capable of containing its own bulk; a further advantage claimed is that the helicopter would be able to remain stationary in the air, maintaining itself in any position by the vertical lift of its propeller.
