ENGLISH 三上悠亚snis674在线播放47LOUVAIN UNDER THE MAILED FIST

"Louvain,Pneumatic machinery, aside from results due to the elasticity of air, is analogous in operation to hydraulic machinery.Matters stood so in Lige on the morning of August 9th, when the second day of the occupation by the Germans had not yet passed. The Belgian field army, which had bravely defended the ground under the protection of the forts, and inflicted heavy losses upon the Germans, had to retreat before their superior numbers, leaving the further defence of the Meuse to the forts. But a high price had been paid for Lige, for the German losses were immense, and on the ninth they were still busy burying their dead. The Germans lost many men, especially near Lixhe and the Forts Bachon and Fleron.

I myself ran great risks too, but I did not mind, and walked on, moved by a consuming desire to get to Lige, and then back to Maastricht, to be able to wire to my paper that I had been to Lige only just after it was taken by the Germans, and that the news, wired from Germany to the Netherland papers, that the forts had been taken was untrue.The shelling went on during the night, and all that time the inhabitants remained in their cellars.3. The vertical movement of material, although it consumes more power, is more economical than horizontal handling, because less floor room and ground surface is required.

Another object gained by equal action on both sides of large pieces is the quality of the forgings produced, which is generally improved by the rapidity of the shaping processes, and injured by too frequent heating.Lastly, proportions; having estimated the cutting force required at one ton, although less than the actual strain in a machine of this kind, we proceed upon this to fix proportions, [157] beginning with the tool shank, and following back through the adjusting saddle, the cutting bar, connections, crank pins, shafts, and gear wheels to the belt. Starting again at the tool, or point of cutting, following through the supports of the rack, the jaws that clamp it, the saddle for the graduating adjustment, the connections with the main frame, and so on to the crank-shaft bearing a second time, dimensions may be fixed for each piece to withstand the strains without deflection or danger of breaking. Such proportions cannot, I am aware, be brought within the rules of ordinary practice by relying upon calculation alone to fix them, and no such course is suggested; calculation may aid, but cannot determine proportions in such cases; besides, symmetry, which cannot be altogether disregarded, modifies the form and sometimes the dimensions of various parts.

For the rest most houses in the market-place were on fire. Soldiers were billeted on one of the corner houses, and I was of course detained there, but released again, after having been requested to show up the francs-tireurs. I had to consider also where I might pass the night in this burning city? I asked an officer's consent to stay the night with the soldiers. He gave his permission if I could get the consent of the commanding officer, whom I might find at the station; he told me that he was sure to grant it.In the flowerbeds in front of the station many corpses had been buried, especially those of soldiers who had been killed in the fight near Louvain. The station itself was well guarded, but, thanks to my passport and resolute manner, I gained admission and was finally ushered into the presence of the man who is responsible for the destruction of Louvain, Von Manteuffel.The most perfect castings for gear wheels and pulleys and other pieces which can be so moulded, are made by drawing the patterns through templates without rapping. These templates are simply plates of metal perforated so that the pattern can be forced through them by screws or levers, leaving the sand intact. Such templates are expensive to begin with, because of the accurate fitting that is required, especially around the teeth of wheels, and the mechanism that is required in drawing the patterns, but when a large number of pieces are to be made from one pattern, such as gear wheels and pulleys, the saving of labour will soon pay for the templates and machinery required, to say nothing of the saving of metal, which often amounts to ten per cent., and the increased value of the castings because of their accuracy.

"They were all unrecognisable, their faces were black from smoke, their uniforms in rags, their hands covered with blood. The general was put on a stretcher, and carried outside the fort across the heaps of obstacles; there he was attended to by a surgeon. He had lost consciousness. As soon as he recovered it, he pressed the hands of two Belgian officers. 'It is all over; there is nothing left to defend. But we did our utmost courageously.'Considered as means for transmitting power, the contrast as to advantages and disadvantages lies especially between belts and gearing instead of between belts and shafts. It is true in extreme cases, such as that cited at Crewe, or in conveying water-power from inaccessible places, through long distances, the comparison lies between belts and shafts; but in ordinary practice, especially for first movers, the problem as to mechanism for conveying power lies between belts and gear wheels. If experience in the use of belts was thorough, as it is in the case of gearing, and if the quality of belts did not form so important a part in the estimates, there would be but little difficulty in determining where belts should be employed and where gearing would be preferable. Belts are continually taking the place of gearing even in cases where, until quite recently, their use has been considered impracticable; one of the largest rolling mills in Pittsburg, Pennsylvania, except a single pair of spur wheels as the last movers at each train of rolls, is driven by belts throughout.
