Spring tides will rise 5 to 7 feet above the ordinary level of the tidal portion of the canal, which extends to the next group of locks at Latchford, a distance of twentyone miles. Between that and the docks in Manchester there are three locks and a rise of 60 feet, corresponding to the total fall from level of water in Manchester Docks to level of tide, rising 14 feet 2 inches above Old Dock Sill at Liverpool, this being the ordinary waterlevel in canal between Eastham and...
Seite 168 - ... Nevertheless, from the molecular point of view, much may be said in answer to the question. The mystery is in fact lessened now, as it is known that the mode of existence of carbon in iron follows the laws of ordinary saline solutions. Our knowledge is, however, of very recent origin, and we owe mainly to the Alloys Research Committee of the Institution of Mechanical Engineers...
Seite 160 - The solution theory of carburized iron affirms that this substance is, when fluid, a solution of carbon in iron, and that under certain conditions the solidified mass also forms a solid solution. It further affirms that these liquid and solid solutions obey the ordinary laws of solution, which have been fully studied in the case of aqueous, saline, and organic solutions. The solution theory can, therefore, be invoked to explain both the mode of solidification of carburized iron and the molecular...
