R.A.F. Aeroplane. Barbara. [Aside.] Butcher! Over and over I have been told, "Nick, this is amazing. � So much for the early designs. With regard to engines of this type specially constructed for use with aircraft, three designs call for special mention. Messrs A. Gobe and H. Diard, Parisian engineers, produced an eight-cylindered two-stroke cycle engine of rotary design, the cylinders being co-axial. Each pair of opposite pistons was secured together by a rigid connecting rod, connected to a pin on a rotating crankshaft which was mounted eccentrically to the axis of rotation453 of the cylinders. The crankshaft carried a pinion gearing with an internally toothed wheel on the transmission shaft which carried the air-screw. The combustible mixture, emanating from a common supply pipe, was led through conduits to the front ends of the cylinders, in which the charges were compressed before being transferred to the working spaces through ports in tubular extensions carried by the pistons. These extensions had also exhaust ports, registering with ports in the cylinder which communicated with the outer air, and the extensions slid over depending cylinder heads attached to the crank case by long studs. The pump charge was compressed in one end of each cylinder, and the pump spaces each delivered into their corresponding adjacent combustion spaces. The charges entered the pump spaces during the suction period through passages which communicated with a central stationary supply passage at one end of the crank case, communication being cut off when the inlet orifice to the passage passed out of register with the port in the stationary member. The exhaust ports at the outer end of the combustion space opened just before and closed a little later than the air ports, and the incoming charge assisted in expelling the exhaust gases in a manner similar to that of the earlier types of two-stroke cycle engine. The accompanying rough diagram assists in showing the working of this engine. There was an awe-stricken silence. 色琪琪男人av的天堂 国内自拍久久久久影院 鈥楢nd they tell me you鈥檙e going to be Mayor of Bracebridge next year,鈥?said Mrs Goodford, delighted to have drawn him into conversation with{27} her. If only she could engage him in it she trusted herself to make him lose his temper before many minutes were over. It seemed to Mrs Keeling that this was not being clever but stupid. She felt that it was a designed diversion to distract her thoughts. She was being 鈥榩earl-pendanted鈥?again without the pearl, and was not going to be put off like that. 299 As a result of a number of accidents to monoplanes the Government appointed a Committee at the end of 1912 to inquire into the causes of these. The report, which was presented in March, 1913, exonerated the monoplane by coming to the conclusion that the accidents were not caused by conditions peculiar to monoplanes, but pointed out certain desiderata in aeroplane design generally which are worth recording. They recommended that the wings of aeroplanes should be so internally braced as to have sufficient strength in themselves not to collapse if the external bracing wires should give way. The practice, more common in monoplanes than biplanes, of carrying important bracing wires from the wings to the undercarriage was condemned owing to the liability of damage from frequent landings. They also pointed out the desirability of duplicating all main wires and their attachments, and of using stranded cable for control wires. Owing to the suspicion that one accident at least had been caused through the tearing of the fabric away from the wing, it was recommended that fabric should be more securely fastened to the ribs of the wings, and that devices for preventing the spreading of tears should be considered. In the last connection it is interesting to note that the French Deperdussin firm produced a fabric wing-covering with extra strong threads run at right angles through the fabric at intervals in order to limit the tearing to a defined area. � It was obvious by this time that the family lunch was going to be rather a stormy sort of passage, and Mrs Keeling had before this caught her husband鈥檚 eye, and with dumb movements of her lips and querying eyebrows had communicated 鈥楥hampagne?鈥?to him, for it was known that when Mrs Goodford was in a worrying mood, a glass of that agreeable beverage often restored her to almost fatuous good humour. But her husband had replied aloud, 鈥楥ertainly not,鈥?and assumed his grimmest aspect. This did not look well: as a rule he was content to suffer Mrs Goodford鈥檚 most disagreeable humours in contemptuous silence. Now and then, however, and his wife was afraid that this was one of those tempestuous occasions, he was in no mind to lie prone under insults levelled at him across his own table.
