Disintegrating machines, such as are employed for pulverising various substances, grinding grain or pulp, separating fibrous material, and so on, are, with some exceptions, simple enough to be readily understood. One of these exceptions is the rotary "disintegrators," recently introduced, about the action of which some diversity of opinion exists. The effect produced is certainly [60] abrasive wear, the result of the pieces or particles striking one against another, or against the revolving beaters and casing. The novelty of the process is in the augmented effect produced by a high velocity, or, in other words, the rapidity of the blows.

These various lathes, although of a widely varied construction and adapted to uses more or less dissimilar, are still the engine lathe either with some of its functions omitted to simplify and adapt it to some special work, or with some of the operative parts compounded to attain greater capacity. このページの先頭です

TWO:(1.) What is the difference between geometric and artistic drawing?(2.) What is the most important operation in making a good drawing?(3.) Into what three classes can working drawings be divided?(4.) Explain the difference between elevations and plans.(5.) To what extent in general practice is the proportion of parts and their arrangement in machines determined mathematically?Prout gave his information in a low voice. He could trust Hetty, and besides, she might have some valuable information to impart.
TWO:That runs the motor, Larry agreed. The cable must have slipped on the drum and let the door go downHis parachute isnt loosened or unfolded, he responded, working to get the spark of life to awaken in the man he bent over. No, Larry, from the looks of thingssomebody hit him, while they were away up in the air, and jumpedwith that life preserver.

THREE:"You are welcome;" he said; "it is so dull here that even the conversation of a mere detective is pleasing."In the shadows Hetty listened to as much of the talk as she could hear. But nobody was going to leave the house without her knowledge. Behind the hangings in the hall she waited. Her patience was not unduly tried. There was a light footstep presently, a pause as if of precaution, and the Countess came downstairs. Her hair had become blonde, there was a lace shawl over her head, her skirts were short and trim.

THREE:Next day a sallow, seedy, broken-down shop assistant sought and obtained a bedroom at the Orange Tree public-house. He seemed to have money, and therefore he was welcome. He hinted that he was "in trouble" over some stolen goods from his late employer's shop, and the Orange Tree received him with open arms.In shading drawings, be careful not to use too deep tints, and to put the shades in the right place. Many will contend, and not without good reasons, that working drawings require no shading; yet it will do no harm to learn how and where they can be shaded: it is better to omit the shading from choice than from necessity. Sections must, of course, be shadednot with lines, although I fear to attack so old a custom, yet it is certainly a tedious and useless one: sections with light ink shading of different colours, to indicate the kind of material, are easier to make, and look much better. By the judicious arrangement of a drawing, a large share of it may be in sections, which in almost every case are the best views to work by. The proper colouring of sections gives a good appearance to a drawing, and conveys an idea of an organised machine, or, to use the shop term, "stands out from the paper." In shading sections, leave a margin of white between the tints and the lines on the upper and left-hand sides of the section: this breaks the connection or sameness, and the effect is striking; it separates the parts, [85] and adds greatly to the clearness and general appearance of a drawing.
