Page 169 - Heath, as evidenced by his patent of 1839, in which he declares that his invention consists in " the use of carburet of manganese in any process •whereby iron is converted into cast steel.
Page 382 - Saussure, which were conducted in a manner likely to produce correct results. Each portion of charcoal was heated afresh to a red heat, and allowed to cool under mercury. When taken from the mercury, it was instantly plunged into the vessel of gas : — Ammoniacal gas 90 Muriatic acid gas 85 Sulphurous acid 65 Sulphuretted hydrogen 55 Nitrous oxide 40 Carbonic acid 35...
Page 160 - ... 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.
Page 542 - ... regenerator chequer-work is required to effect the gradual cooling of the products of combustion, and only a small portion near the top, perhaps a fourth of the whole mass, is heated uniformly to the full temperature of the flame ; the heat of the lower portion decreasing gradually downwards nearly to the bottom. Three or four times as much brickwork is thus required in the regenerators, as is equal in capacity for heat to the products of combustion. The best size and arrangement of the bricks...
Page 323 - ... charcoal. So completely is the heat which is disengaged by the burning fuel absorbed by the water in the bath,. that the air discharged at the top pipe is generally the same temperature as the atmosphere.
Page 167 - ... produced of 10 or 20 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...
Page 226 - The furnace is filled with charcoal, and a lighted coal being introduced before the nozzles, the mass in the interior is soon kindled. As soon as this is accomplished, a small portion of the ore, previously moistened with water, to prevent it from running through the charcoal, but without any...
Page 407 - Dartmoor, the peat is cut by the convicts from the prison, working in gangs ; and, after being dried, it is carefully stored in one of the old prisons. From this peat, by a most simple process, gas is made with which the prisons at Princetown are lighted. The illuminating power of this gas is very high. The charcoal left after the separation of the gas is used in the same establishment for fuel and for sanitary purposes, and the ashes eventually go to improve the cultivated lands of that bleak region....
