Seite 534 - The air expanding in volume, divides itself into globules, or bursts violently upwards, carrying with it some hundredweight of fluid metal, which again falls into the boiling mass below. Every part of the apparatus trembles under the violent agitation thus produced, a roaring flame rushes from the mouth of the vessel, and as the process advances, it changes its violet colour to orange, and finally to a voluminous pure white flame.
Seite 532 - ... and that cold shortness resulted from the presence of a like quantity of phosphorus ; it therefore became necessary to remove those substances. Steam and pure hydrogen gas were tried with more or less success in the removal of sulphur, and various fluxes composed chiefly of silicates of the oxide of iron and manganese, were brought in contact with the fluid metal during the process, and the quantity of phosphorus was thereby reduced. Thus many months were consumed in laborious and expensive experiments;...
Seite 26 - They are a frugal, industrious, and intelligent race, inhabiting a district for the most part inferior in natural fertility to the southern portion of Ireland, but cultivating it better, and paying higher rents in proportion to the quality of the land, notwithstanding the higher rate of wages.
Seite 334 - It will thus be seen, that the quality of the iron regularly increased up to No. 6 (the slight difference of No. 5 may perhaps be attributed to the sample being slightly defective) ; and that from No. 6 the descent was in a similar ratio to the previous increase.
Seite 210 - ... the principal dimensions of the Engines and Vessels, draught of water, tonnage, speed, consumption of fuel, &c. 23. The best forms for river and seagoing Steam Vessels ; with practical examples.
Seite 542 - ... tons in weight in a single piece, and two or three such pieces might be conveniently made by the same apparatus in one day. The metal so made might be either soft malleable iron or soft steel. In order to prove the extreme toughness of such iron, and the strain to which it might be subjected without bursting, several cast and hammered cylinders were placed cold under the steam-hammer, and were crushed down without the least tearing of the metal, as was shown by the samples exhibited. These cylinders...
Seite 536 - ... to one vastly greater than the highest known welding heats, by which malleable iron only becomes sufficiently soft to be shaped by the blows of the hammer ; but here it becomes perfectly fluid, and even rises so much above the meltingpoint, as to admit of its being poured from the converter into a founder's ladle, and from thence to be transferred to several successive moulds.
Seite 219 - New Method of Teaching the Science of Mechanical and Engineering Drawing; with some Practical Remarks on the Teeth of Wheels, the Projection of Shadows, Principles of Shading, and the Practice of Making to Scale Drawings from Actual Machinery.
Seite 453 - Two measurements of length are made from the poll to the tip of the horn, one on the inside and the other on the outside of the horn.
