TWO:1. The strength of shafts is governed by their size and the arrangement of their supports.He thought that it was sufficiently protected by the immense Red Cross flag, and the words written on the door by the Germans themselves: "Professor Noyons, Netherland physician, to be spared." But he had been mistaken. The soldiers did not respect anything, and had forced an entry into the house, wounded that servant, and then wrecked everything in the most scandalous manner. Beautiful large Japanese jars had been smashed to pieces, valuable furniture damaged by knocking and breaking large pieces out of it with rifles and bayonets. A fine carpet was burned, as well as many pieces of furniture. A hole was burned even in the floor.
ONE:Another principle in planing machines which deserves notice is the manner of driving carriages or platens; this is usually performed by means of spur wheels and a rack. A rack movement is smooth enough, and effective enough so far as a mechanical connection between the driving gearing and a platen, but there is a difficulty met with from the torsion and elasticity of cross-shafts and a train of reducing gearing. In all other machines for metal cutting, it has been a studied object to have the supports for both the tools and the material as rigid as possible; but in the common type of planing machines, such as have rack and pinion movement, there is a controversion of this principle, inasmuch as a train of wheels and several cross-shafts constitute a very effective spring between the driving power and the point of cutting, a matter that is easily proved by planing across the teeth of a rack, or the threads of a screw, on a machine arranged with spur wheels and the ordinary reducing gearing. It is true the inertia of a platen is interposed and in a measure overcomes this elasticity, but in no degree that amounts to a remedy.Two courses were offered to the Sky Patrol with Jeff.
TWO:Tools should never be tempered by immersing their edges or cutting parts in the bath, and then allowing the heat to "run down" to attain a proper temper at the edge. I am well aware that this is attacking a general custom, but it is none the less wrong for that reason. Tools so hardened have a gradually diminishing temper from their point or edge, so that no part is properly tempered, and they require continual re-hardening, which spoils the steel; besides, the extreme edge, the only part which is tempered to a proper shade, is usually spoiled by heating and must be ground away to begin with. No latheman who has once had a set of tools tempered throughout by slow drawing, either in an oven, or on a hot plate, will ever consent to point hardening afterwards. A plate of iron, two to two and one-half inches thick, placed over the top of a tool dressing fire, makes a convenient arrangement for tempering tools, besides adding greatly to the convenience of slow heating, which is almost as important as slow drawing. The writer has by actual experiment determined that the amount of tool dressing [117] and tempering, to say nothing of time wasted in grinding tools, may in ordinary machine fitting be reduced one-third by "oven tempering.""Here they are, with your signature on the back of every one of them," he said. "There is nothing singular about that, seeing that so many tradesmen insist upon having banknotes endorsed. Question is, What's the explanation?"
ONE:And the commanding officer gave me a pass, on which this very same colonel who had prohibited me to write in my paper what troops were at Riemst, put a stamp on that pass, which contained the German eagle, and besides this the words: "Royal Prussian 8, Reserve Infantry Regiment, II Battalion." This confirmed what the rumours said, that the troops who had passed through Vis and other places during the last days and committed those atrocities there, were the reserves which had been called up, among whom discipline is less strict than among the younger men, who arrived in these districts during the earlier days.There, neatly arranged, was the row of chewed bits of gum!
