Stringfellow himself explained the failure as follows:鈥? Pilcher鈥檚 first glides, which he carried out on a grass hill on the banks of the Clyde near Cardross, gave little result, owing to the exaggerated dihedral angle of the wings, and the absence of a horizontal tail. The 鈥楤at鈥?was consequently reconstructed with a horizontal tail-plane added to the vertical one, and with the wings lowered so that the tips were only six inches above the level of the body. The machine now gave far better results; on the first glide into a head wind Pilcher rose to a height of twelve feet and remained in the air for a third of a minute; in the second attempt a rope was used to tow the glider, which rose to twenty feet and did not come to earth again until103 nearly a minute had passed. With experience Pilcher was able to lengthen his glide and improve his balance, but the dropped wing tips made landing difficult, and there were many breakages. He rose from his seat beside her, and walked impatiently up and down the room. Nothing irritated him so much as to be called on for sentiment or tenderness. 高清性色生活片,一级特黄夫妻生活片,免费成年性色生活片 For some time pride of place among British Vee type engines was held by the Sunbeam Company, which, owing to the genius of Louis Coatalen, together with the very high standard of construction maintained by the firm, achieved records and fame in the middle and later periods of the war. Their 225 horse-power twelve-cylinder engine ran at a normal speed of 2,000 revolutions per minute; the air-screw was driven through gearing at half this speed, its shaft being separate from the timing gear and carried in ball-bearings on the nose-piece of the engine. The cylinders were of cast-iron, entirely water-cooled; a thin casing formed the water-jacket, and a very light design was obtained, the weight being only 3鈥? lbs. per horse-power. The first engine of Sunbeam design had eight cylinders and developed 150 horse-power at 2,000 revolutions per minute; the final type of Vee design produced during the war was twelve-cylindered, and yielded 310 horse-power with cylinders 4鈥? inches bore by 6鈥? inches stroke. Evidence in favour of the long-stroke engine is afforded in this type as regards economy of working; under full load, working at 2,000 revolutions per minute, the consumption was 0鈥?5 pints of fuel per brake horse-power per hour, which seems to indicate that the long stroke permitted of full use being made of the power resulting from each explosion, in spite of the high rate of speed of the piston.  There was something in her face which checked further speech on Lydia's part. Lydia was fairly frightened. She crept away to the garret, where Polly was already sleeping soundly, and vainly tried to rouse her fellow-servant, to feel some interest in her account of how missus had stalked into the house by herself like a ghost, and had ordered her off to bed, and to get up a discussion as to missus's strange goings on altogether of late. 鈥淭he day after to-morrow.鈥?
