Seite 173 - ... less dense than that used for smelting iron. In the north of England, a charge of coal generally remained in the oven during 48 hours ; in London, only 36 hours ; he made lighter charges and coked them in 24 hours. He still found the calorific effect of 8 or 9 Ibs. of coke to be equal to that of 12 Ibs. of coal ; in his ovens, 20 cwt. of coal produced 14 cwt. of coke. Mr. Parkes inquired, which was the best method of annealing tubes for water gauges on boilers ? He generally used those prepared...
Seite 170 - ... and thus unfit for use. It is the same with the glass made for the flat bore tubes for thermometers, which are never annealed, because the smoke of the annealing furnace would render the interior of the bore unfit for the reception of the mercury. These tubes will only bear the heat of the blowpipe when they are made from a metal which has been produced under all the favourable circumstances before described. It is, therefore, to be inferred, that the most homogeneous and perfect flint glass...

Seite 236 - Selby line was opened with the engines of the former order, but the public and the Company being so much annoyed by hot cinders from their chimneys, burning whatever they lighted upon, and rapidly destroying the smoke-boxes themselves, three of those engines were altered, and succeeded to a considerable extent in diminishing the nuisance, whilst the engines performed better and with less fuel. That fact,. however, being questioned, and two engines of the improved construction having got to work,...
Seite 172 - Glass being sometimes deteriorated in the process of reheating, not only in color, but in its faculty of welding, by the sulphur existing in the coal or coke used in the furnace ; this is prevented by occasionally throwing about a quart of cold water on the fire ; the explosive vapour thus raised carries off the sulphureous gas. The process of annealing has the remarkable property of carrying off from the glass the reddish tint imparted to it by manganese, and in large masses, not only the reddish...
