FORE:3. Two elevations taken at right angles to each other, fix all points, and give all dimensions of parts that have their axis parallel to the planes on which the views are taken; but when a machine is complex, or when several parts lie in the same plane, three and sometimes four views are required to display all the parts in a comprehensive manner.In casting and forging operations the material is treated while in a heated and expanded condition; the nature of these operations is such that accurate dimensions cannot be attained, so that both forgings and castings require to be made enough larger than their finished dimensions to allow for shrinkage and irregularities. Finishing as a process consists in cutting away this surplus material, and giving accurate dimensions to the parts of machinery when the material is at its natural temperature. Finishing operations being performed as said upon material at its normal temperature permits handling, gauging and fitting together of the parts of machinery, and as nearly all other processes involve heating, finishing may be called the cold processes of metal work. The operations of a fitting shop consist almost entirely of cutting, and grinding or abrading; a proposition that may seem novel, yet these operations comprehend nearly all that is performed in what is called fitting.

FORE:From warehouses and from shops bales of corn, flour, sugar, and other goods were taken, thrown in heaps and then placed on all sorts of carts and motors. In the most frequented parts military bands had taken their stand, and played amidst the loud jubilation of the soldiers."In short the town of Dinant is destroyed. Of 1,400 houses, 200 only remained standing. The factories, where the labouring population got their bread and butter, were wrecked systematically. Many inhabitants were sent to Germany, where they are still kept as prisoners. The majority of the others are scattered all over Belgium. Those who stayed in the towns were starved.

THREE: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 [79] 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."In fact," he said, "the customer who gave them me is now in the shop."

TWO:"Whilst some soldiers committed these murders, others looted and wrecked the houses, smashed the safes or blew them up with dynamite. They forced their way into the Banque Centrale de la Meuse, seized the manager, Mr. Xavier Wasseige, and called upon him to open the safe. As he refused to do so, they tried to force it open, but in vain. Thereupon they took Mr. Wasseige and his two eldest sons to the Place d'Armes, where they and 120 of their fellow-citizens were shot by means of a mitrailleuse. The youngest three children of Mr. Wasseige were held by soldiers and forced to attend the slaughter of their father and brothers. We were also informed that one of the young Wasseiges lay dying for an hour and nobody dared to come to his assistance.

TWO:Both friends and cities and confederates,

TWO:And turned their savage life to civil ways;It was impossible to suspect Hetty of being an actress. The girl was too open and natural for that. And in his queer way Balmayne admired the gentle womanliness of an innocent girl.

TWO:Shaping machines as machine tools occupy a middle place between planing and slotting machines; their movements correspond more to those of slotting machines, while the operation of the tools is the same as in planing. Some of the advantages of shaping over planing machines for certain kinds of work are, because of the greater facilities afforded for presenting and holding small pieces, or those of irregular shape; the supports or tables having both vertical and horizontal faces to which pieces may be fastened, and the convenience of the mechanism for adjusting and feeding tools.It has already been observed that the thoughts of Socrates were thrown into shape for and by communication, that they only became definite when brought into vivifying contact with another intelligence. Such was especially the case with his method of ethical dialectic. Instead of tendering his advice in the form of a lecture, as other moralists have at all times been so fond of doing, he sought out some pre-existing sentiment or opinion inconsistent with the conduct of which he disapproved, and then gradually worked round from point to point, until theory and practice were exhibited in immediate contrast. Here, his reasoning, which is sometimes spoken of as exclusively inductive, was strictly syllogistic, being the application of a general law to a particular instance. With the growing emancipation of reason, we may observe a return to the Socratic method of moralisation. Instead of rewards and punishments, which encourage selfish calculation, or examples, which stimulate a mischievous jealousy when they do not create a spirit of servile imitation, the judicious trainer will find his motive power in the pupil��s incipient tendency to form moral judgments, which, when reflected on the155 individual��s own actions, become what we call a conscience. It has been mentioned in the preceding chapter that the celebrated golden rule of justice was already enunciated by Greek moralists in the fourth century B.C. Possibly it may have been first formulated by Socrates. In all cases it occurs in the writings of his disciples, and happily expresses the drift of his entire philosophy. This generalising tendency was, indeed, so natural to a noble Greek, that instances of it occur long before philosophy began. We find it in the famous question of Achilles: ��Did not this whole war begin on account of a woman? Are the Atreidae the only men who love their wives?��99 and in the now not less famous apostrophe to Lycaon, reminding him that an early death is the lot of far worthier men than he100��utterances which come on us with the awful effect of lightning flashes, that illuminate the whole horizon of existence while they paralyse or destroy an individual victim.

THREE:Irregularity of cooling may be the result of unequal conducting power in different parts of a mould or cores, or it may be [98] 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.
