THREE:An interesting example in the use of belts for communicating power to movable machinery is furnished by the travelling cranes of Mr Ramsbottom, in the shops of the L. & N. W. Railway, at Crewe, England, where powerful travelling cranes receive both the lifting and traversing power by means of a cotton rope not more than three-fourths of an inch in diameter, which moves at a high velocity, the motion being reduced by means of tangent wheels and gearing to attain the force required in lifting heavy loads. Observing the operation of this machinery, a person not familiar with the relations between force and motion will be astonished at the effect produced by the small rope which communicates power to the machinery.The successful application of the pneumatic system at the Mont Cenis Tunnel in Italy, and at the Hoosac Tunnel in America, has demonstrated the value of the system where the air not only served to transmit power to operate the machinery but to ventilate the mines at the same time. Air brakes for railway trains are another example illustrating the advantages of pneumatic transmission; the force being multiplied at the points where it is applied, so that the connecting pipes are reduced to a small size, the velocity of the air making up for a great force that formerly had to be communicated through rods, chains, or shafts. The principal object attained by the use of air to operate railway brakes is, however, to maintain a connection throughout a train by means of flexible pipes that accommodate themselves to the varying distance between the carriages. Presuming that the flow of air in pipes is not materially impeded by friction or angles, and that there will be no difficulty in maintaining lubrication for pistons or other inaccessible parts of machinery when driven by air, there seems to be many reasons in favour of its use as a means of distributing power in manufacturing districts. The diminished cost of motive power when [56] it is generated on a large scale, and the expense and danger of maintaining an independent steam power for each separate establishment where power is employed, especially in cities, are strong reasons in favour of generating and distributing power by compressed air, through pipes, as gas and water are now supplied.

FORE:Proceeding from these premises, the first thing should be to examine the action of existing valve gear, to determine where this want of the dead-stroke function can best be supplied, and to gain the aid of such suggestions as existing mechanism may offer, also to see how far the appliances in use may become a part of any new arrangement.

FORE:"And let that woman go? I tell you never. The very stones in the street would cry out at me! You hear that knocking at the door? Go and open it."Still more important than these observations themselves is the great truth he derives from them��since rediscovered and worked out in detail by Von Baer��that in the development of each individual the generic characters make their appearance before the specific characters.211 Nor is this a mere accidental or isolated remark, but, as we shall show in the next chapter, intimately connected with one of the philosopher��s metaphysical theories. Although not an evolutionist, he has made other contributions to biology, the importance of which has been first realised in the light of the evolution theory. Thus he notices the antagonism between individuation and reproduction;212 the connexion of increased size with increased vitality;213 the connexion of greater mobility,214 and of greater intelligence,215 with increased complexity of structure; the physiological division of labour in the higher animals;216 the formation of heterogeneous organs out of homogeneous tissues;217 the tendency towards greater centralisation in the higher organisms218��a remark connected with his two great anatomical discoveries, the central position of the heart in the vascular system, and the possession of a backbone by all red-blooded animals;219 the resemblance of animal intelligence to a rudimentary human intelligence, especially as manifested in children;220 and, finally, he attempts to trace a continuous series of gradations connecting the inorganic with the organic world, plants with animals, and the lower animals with man.221

FORE:Materials consumed in an engineering establishment consist mainly of iron, fuel, sand, and lumber. These articles, or their products, during the processes of manipulation, are continually approaching the erecting shop, from which finished machinery [72] is sent out after its completion. This constitutes the erecting shop, as a kind of focal centre of a works, which should be the base of a general plan of arrangement. This established, and the foundry, smithy, finishing, and pattern shops regarded as feeding departments to the erecting shop, it follows that the connections between the erecting shop and other departments should be as short as possible, and such as to allow free passage for material and ready communication between managers and workmen in the different rooms. These conditions would suggest a central room for erecting, with the various departments for casting, forging, and finishing, radiating from the erecting shop like the spokes of a wheel, or, what is nearly the same, branching off at right angles on either side and at one end of a hollow square, leaving the fourth side of the erecting room to front on a street or road, permitting free exit for machinery when completed.

THREE:Formerly an apprentice entered a shop to learn hand skill, and to acquaint himself with a number of mysterious processes; to learn a series of arbitrary rules which might serve to place him at a disadvantage even with those whose capacity was inferior and who had less education; but now the whole is changed. An engineer apprentice enters the shop with a confidence that he may learn whatever the facilities afford if he will put forth the required efforts; there are no mysteries to be solved; nearly all problems are reached and explained by science, leaving a greater share of the shop-time of a learner to be devoted to studying what is special.

FORE:409A set of lathe tools should consist of all that are required for every variety of work performed, so that no time will be lost by waiting to prepare tools after they are wanted. An ordinary engine lathe, operating on common work not exceeding [126] twenty inches of diameter, will require from twenty-five to thirty-five tools, which will serve for every purpose if they are kept in order and in place. A workman may get along with ten tools or even less, but not to his own satisfaction, nor in a speedy way. Each tool should be properly tempered and ground, ready for use 'when put away;' if a tool is broken, it should at once be repaired, no matter when it is likely to be again used. A workman who has pride in his tools will always be supplied with as many as he requires, because it takes no computation to prove that fifty pounds of extra cast steel tools, as an investment, is but a small matter compared to the gain in manipulation by having them at hand. THREE:Cynicism, if we understand it rightly, was only the mutilated form of an older philosophy having for its object to set morality free from convention, and to found it anew on a scientific knowledge of natural law. The need of such a system was not felt so long as Plato and Aristotle were unfolding their wonderful schemes for a reorganisation of action and belief. With the temporary collapse of those schemes it came once more to the front. The result was a new school which so thoroughly satisfied the demands of the age, that for five centuries the noblest spirits of Greece and Rome, with few exceptions, adhered to its doctrines; that in dying it bequeathed some of their most vital elements to the metaphysics and the theology by which it was succeeded; that with their decay it reappeared as an important factor in modern thought; and that its name has become imperishably associated in our own language with the proud endurance of suffering, the self-sufficingness of conscious rectitude, and the renunciation of all sympathy, except what may be derived from contemplation of the immortal dead, whose heroism is7 recorded in history, or of the eternal cosmic forces performing their glorious offices with unimpassioned energy and imperturbable repose.Charlton rose; the woman's coolness and nerve were inflammable to him.
