1. The strength of shafts is governed by their size and the arrangement of their supports."The burgomaster informs the population that any utterance contrary to the regulations will be severely punished.
5. The obvious means of attaining this independent movement of the valve gear, is by the momentum of some part set in motion by the hammer-drop, or by the force of gravity reacting on this auxiliary agent.When I was eating a little at one of the hotels near the railway station, I was offered the newspaper l'Ami de l'Ordre, which had appeared again for the first time on that day, September 7th, under the Censorship of the German authorities. For curiosity's sake I translate here the first leaderette, published under the rule of the new masters:—In handling a weight with the hands it is carefully raised, and laid down with care, but moved as rapidly as possible throughout the intervening distance; this lesson of nature has not been disregarded. We find that the attention of engineers has been directed to this principle of variable speed to be controlled at will. The hydraulic cranes of Sir William Armstrong, for example, employ this principle in the most effective manner, not only securing rapid transit of loads when lifted, but depositing or adjusting them with a care and precision unknown to mechanism positively geared or even operated by friction brakes.
Whenever our escort fancied that they saw something, they stopped and called out to the supposed approaching persons: "Who goes there?" Some125times it was only some shrubs that they saw; at other times patrolling German soldiers. "Parole?" was asked: "Duisburg!" and after that answer they came nearer. At the station I was taken to an officer who sat at a table on the platform and had lit up his nearest surroundings by means of a paraffin-lamp. My little old man wept now so badly that he was quite unmanageable, and the officer made up his mind to get rid of him as quickly as possible.
Chasing produces screws true with respect to their axis, and is the common process of threading all screws which are to have a running motion in use, either of the screw itself, or the nut.The poor wretches, who expected to be killed at any moment, were driven into squares or the meadows, where they were exposed to the chilly night air, so that several babies perished. Only the next morning were the women and children allowed to leave—that is to say, they were told to take the shortest way to Maastricht.I saw some extremely poor people, very old and stiff, to whom walking was nearly impossible. A Bavarian soldier escorted them. He had his rifle slung across his back and in both hands carried the luggage of the unfortunate creatures. He seemed to have come a long way already, for he looked tired, and the perspiration ran down his face. Although it is only natural to assist one's fellow-creatures, this scene touched me, for hitherto I had seen the Germans commit rough, inhuman deeds only.
(1.) How may gauging implements affect the division of labour?—(2.) In what way do standard dimensions affect the value of machinery?—(3.) Why cannot cylindrical joints be fitted by trying them together?—(4.) Under what circumstances is it most important that the parts of machinery should have standard dimensions?—(5.) Which sense is most acute in testing accurate dimensions?—(6.) How may slight variations in dimensions be made apparent to sight?CHAPTER XXX. TURNING LATHES.The Destruction of Dinant
Near Haccourt, by the bank of the Meuse, I noticed a terrible glare of fire and dense smoke. It was an alarming sight, and made me fear the direst things. I considered for a moment whether I should go there or not, fearing that I had already taxed my nerves too much. Yet, I made up my mind to go, and by a side-way got to the Meuse, near Visé. German engineers were busy here laying telephone wires, and an officer stopped me, threatening me with his revolver. It was obvious that they were no longer accustomed to see civilians on that road. After having examined my passport and seeing that I was a Netherland journalist, he became very friendly, and politely urged me not to go farther."We are neutrals!"
Considered as a mechanical agent, a hammer concentrates the power of the arms, and applies it in a manner that meets the requirements of various purposes. If great force is required, a long swing and slow blows accomplish tons; if but little force is required, a short swing and rapid blows will serve—the degree of force being not only continually at control, but also the direction in which it is applied. Other mechanism, if employed instead of hammers to perform a similar purpose, would require to be complicated  machines, and act in but one direction or in one plane.Group after group went by, and I heard French and Netherland, the Maastricht vernacular and sweet Flemish spoken, all sorts of tongues and modes of utterance. The men were bare-headed, and each let his rosary slip through his fingers. Soon after the head of the procession reached Our Lady Square the huge church was packed, and those who could not find room inside stood in the square, which also very soon was full with these thousands of people in a dense mass, like so many blades of grass in a meadow.
Just outside Tongres I met a fleet of Red Cross cars loaded with wounded. Cavalry escorted them. I was stopped and ordered to go back, as they expected the Belgians to attack Tongres.Very many other cases of martyrdom among priests remained unknown to me, but the various Belgian bishops examined all these events with praiseworthy zeal and scrupulousness, and by taking extensive evidence established the fact that in no case the victims could be reproached with any act that justified the sentence against them. After the war the world will surely be made acquainted with the horrible truth.
The lathe as a tool for producing heliacal forms would occupy a prominent place among machine tools, if it were capable of performing no other work; the number of parts of machinery which have screw-threads is astonishing; clamping-bolts to hold parts together include a large share of the fitting on machinery of all kinds, while screws are the most common means for increasing power, changing movements and performing adjustments.It was a fine summer afternoon, and the sun shone on the many bright, whitewashed walls of the old and neat little town, built close to the rapidly flowing river. There was quiet in the streets, although nearly all the inhabitants were sitting on their chairs in the streets. But nobody ventured to move about, and conversations were held only in whispers. As I walked through the village street in my quaint get-up, they pushed their chairs a little closer together as if frightened, and looked shyly at me as if they feared that I was not the harbinger of much good. And all these hundreds of people saluted me humbly, almost cringingly, which filled me with pity.Fifth.—Shrinkage; the allowance that has to be made for the contraction of castings in cooling, in other words, the difference between the size of a pattern and the size of the casting. This is a simple matter apparently, which may be provided for in allowing a certain amount of shrinkage in all directions, but when the inequalities of shrinkage both as to time and degree are taken into account, the allowance to be made becomes a problem of no little complication.
Pastor Claes, mentioned in the above proclamation, has done very much for the miserable Louvain population; they owe him especially much gratitude for an act of devotion with regard to the murdered victims.From the other side came two soldiers, one of whom she recognised, as he had been billeted on her. Constantly weeping, her face distorted, she sent another glance towards that fiery blaze, looked at the soldier as if reprovingly, hesitated a moment, but then pressed the enemy's hand, sobbing: "Adieu!—adieu!""On August 14th, at about four o'clock in the afternoon, the expected storm burst; for twenty-five hours the invisible siege-guns poured their torrent of projectiles on the fort. Flares of fire and dense clouds of smoke belched through the crevices. As the enemy's batteries could not be located, their fire could not be answered. The artillerists of the garrison were then taken to the spacious chief gallery, which offered a safe refuge under its vault, about two and a half to three yards thick. Outside the sentries were watching. In the parts near the entrance it was unendurable; the heavy projectiles from the guns mounted in the town had nibbled away the outer wall, only a yard and a half thick. There were as yet no casualties among the garrison; calmly they waited for the infernal tempest to subside and the enemy to storm the fort, for they had sworn to repulse the assault.
