ENGLISH julia京香和波多野结衣合集Many shops were closed on account of lack of stock, as everything had been requisitioned, and as yet no traffic was allowed to bring in fresh pro109visions. All this bother made the inhabitants discontented, but frightened them at the same time; they grumbled and whispered, and looked about with malicious, flaming eyes, but in mortal fear.Leaving out problems of mechanism in forging machines, the adaptation of pressing or percussive processes is governed mainly by the size and consequent inertia of the pieces acted upon. In order to produce a proper effect, that is, to start the particles of a piece throughout its whole depth at each blow, a certain proportion between a hammer and the piece acted upon must be maintained. For heavy forging, this principle has led to the construction of enormous hammers for the performance of such work as no pressing machinery can be made strong enough to execute, although the action of such machinery in other respects would best suit the conditions of the work. The greater share of forging processes may be performed by either blows or compression, and no doubt the latter process is the best in most cases. Yet, as before explained, machinery to act by pressure is much more complicated and expensive than hammers and drops. The tendency in practice is, however, to a more extensive employment of press-forging processes.CHAPTER XXXV. MILLING.
With a thorough knowledge of practical machine operation, and an acquaintance with existing practice, an engineer proceeding upon such a plan, will, if he does not overlook some of the conditions, be able to generate designs which may remain without much modification or change, so long as the purpose to which the machinery is directed remains the same.
Among the improvements in machine fitting which have in recent years come into general use, is the employment of standard gauges, by means of which uniform dimensions are maintained, and within certain limits, an interchange of the parts of machinery is rendered possible.48

Irregularity of cooling may be the result of unequal conducting power in different parts of a mould or cores, or it may be  from the varying dimensions of the castings, which contain heat as their thickness, and give it off in the same ratio. As a rule, the drag or bottom side of a casting cools first, especially if a mould rests on the ground, and there is not much sand between the castings and the earth; this is a common cause of unequal cooling, especially in large flat pieces. Air being a bad conductor of heat, and the sand usually thin on the cope or top side, the result is that the top of moulds remain quite hot, while at the bottom the earth, being a good conductor, carries off the heat and cools that side first, so that the iron 'sets' first on the bottom, afterwards cooling and contracting on the top, so that castings are warped and left with inherent strains.I had to listen to a prolonged hymn of praise of the Netherlanders, who were such sensible people, and the best friends of the Germans; protestations which did not interest me in the least at that moment. On the contrary, it struck me as deplorable that this man did not say a single word of his own accord about the horrible thing happening close by: the destruction of an entire community! He did not seem to attach any importance to it....
An apprentice in entering the workshop should avoid everything tending to an appearance of fastidiousness, either of manner or dress; nothing is more repulsive to workmen, and it may be added, nothing is more out of place in a machine shop than to divide one's time between the work and an attempt to keep clean. An effort to keep as neat as the nature of the work will admit is at all times right, but to dress in clothing not appropriate, or to allow a fear of grease to interfere with the performance of work, is sure to provoke derision.I then tried to find the nunnery of the S?urs de la Misricorde, where one of my cousins had taken the veil. At last, in the Rue des Clarisses I found the huge door of the monastery, and rang the bell. After a few moments a small trellised shutter in the stout door was opened ajar, and a tremulous voice asked in French what I wanted. I assumed that42 it was one of the nuns, but I could see nothing through that narrow jar.
On Thursday everyone, even the persons staying in the Institution and hospitals, were ordered to leave the town, as it was to be shelled. They seemed to have no pity even on the wretched wounded men. Only the male and female nurses remained with these, of their own free will, determined to die with them if necessary.In this way I got into conversation with a middle-aged lady. Her husband had been shot, and she got a bullet in her arm, which had to be amputated in consequence. The poor creature had lost all courage, and lived on her nerves only. It was remarkable to hear this father find the right words, and succeed in making her calm and resigned.138 Before she left us, she had promised that for her children's sake she would do all in her power to control herself.It is easy to learn "how" to draw, but it is far from easy to learn "what" to draw. Let this be kept in mind, not in the way of  disparaging effort in learning "how" to draw, for this must come first, but in order that the objects and true nature of the work will be understood.

It is not the intention to discuss patent law, nor even to estimate what benefits have in the past, or may in the future, be gained to technical industry by the patent system, but to impress engineering apprentices with a better and more dignified appreciation of their calling than to confound it with chance invention, and thereby destroy that confidence in positive results which has in the past characterised mechanical engineering; also to caution learners against the loss of time and effort too often expended  in searching after inventions.Strains suggest special arrangement, which is quite a distinct matter from general arrangement, the latter being governed mainly by the convenience of manipulation. Special arrangement deals with and determines the shape of framing, following the strains throughout a machine. In the present case we have a cutting strain which may be assumed as equal to one ton, exerted between the bracket or jaws which support the work, and the crank-shaft. It follows that between these two points the metal in the framing should be disposed in as direct a line as possible, and provision be made to resist flexion by deep sections parallel with the cutting motion.4. The value of handling machinery, or the saving it effects, is as the constancy with which it operates; such machinery may shorten the time of handling without cheapening the expense.
As we crossed the bridge, I asked my escort why these houses were set on fire. I heard then, for the first time, that "they had been shooting," and they told me of cowardly civilians, who shot from the windows at unsuspicious soldiers, or24 stabbed them treacherously. But of course they had experienced nothing of the kind; it had happened to troops who were now moving ahead. They had, however, taken part in the revenge, and told of it with glittering eyes: how they fired the houses of francs-tireurs and then shot the people who, nearly stifled, appeared at the windows; how in "holy" anger, in order to avenge their comrades, they subsequently entered the houses and destroyed everything. I did not answer, did not know what to think of it, but shuddered, because it was so gruesome.Mr. Derricks lived at Roelanche, but with his wife and seven children had fled for security to Canne, where he was hospitably received in Mr. Poswick's, the burgomaster's, house.
