Seite 101 - President, in the Chair. The Minutes of the last General Meeting were read and confirmed. The CHAIRMAN announced that the Ballot Papers had been opened by the Committee appointed for the purpose, and the following New Members were duly elected : — MEMBERS.
Seite 123 - ... with the carbon contained in the crude iron and produces a most intense combustion, the whole mass being in fact a perfect mixture of metal and fire. The carbon is now burnt off so rapidly as to produce a series of harmless explosions, throwing out the fluid slag in great quantities ; while the combustion of the gases is so perfect that a voluminous white flame rushes from the mouth of the vessel, illuminating the whole building and indicating to the practised eye the precise condition of the...
Seite 123 - Short ridge, under the name of homogeneous metal, are prominent examples of the successful adaptation of cast steel to engineering purposes. The manufacture of cast steel by Huntsman's process is so extensively practised and is so well known that it is unnecessary to do more than...
Seite 154 - ... alternately in opposite directions on the piers requires the addition of oblique piles to act as struts on both sides of the piers. The piers are composed of hollow cylindrical cast iron piles, of 1 inch thickness of metal and 2 feet 6 inches outside diameter, cast in 9 feet lengths weighing about 1 J tons each, as shown enlarged in Figs. 11 to 14, Plate 40 ; these are of two principal patterns, for the portions of the piles above and below the ground. Those above the ground, Figs.- 13 and 14,...
Seite 123 - The blast now rushes upwards into the fluid metal from each of the 49 holes of the tuyeres, producing a most violent agitation of the whole mass. The silicium always present in greater or less quantities in pig iron is first attacked, and unites readily with the oxygen of the air, producing silicic acid : at the same time a small portion of the iron undergoes oxidation, and hence a fluid silicate of the oxide of iron is formed, a little carbon being simultaneously burnt off. The heat is thus gradually...
Seite 118 - Two methods of producing large masses of wrought iron have been in use : the first by the process of building up under the steam hammer, and the second by building up under the rolls. Under the steam hammer, the plate is produced^ by welding together lumps or masses of scrap iron ; each mass of scrap being added and welded to the end of the plate, until it reaches the required length. Plates made in this way have been seriously objected to on account of their brittleness ; and it is reasonable to...
Seite 5 - Council in rotation, will go out of office this day, according to the rules of the Institution ; and the ballot will be taken at the present annual meeting for the election of the Officers and Council for the ensuing year. SUBJECTS FOR PAPEES.
Seite 123 - By this process from 1 to 10 tons of crude iron may be converted into cast steel in 30 minutes, without employing any fuel except that required for melting the pig iron and for the preliminary heating of the converting vessel, the process being effected entirely without manipulation. The loss on the weight of crude iron is from 14 to 18 per cent. with English iron worked in small quantities...
Seite xviii - Clarence Iron Works, Leeds. 1858. Taylor, James, Britannia Engine Works, Cleveland Street, Birkenhead. 1862. Taylor, John, Mining Engineer, 6 Queen Street Place, Upper Thames Street, London, EC 1867.
Seite 117 - The manufacturer-s business is simply to make the best and strongest armour which at the present time is wanted, and leave future possible requirements to be dealt with when the benefits of experience have been obtained . It does not come within the province of this paper to discuss the several questions involved in determining the best form of vessel to carry the weight of armour, nor to settle the resisting power of iron as compared with -wood.
