Strona 147 - FELKIN, HM— Technical Education in a Saxon Town. Published for the City and Guilds of London Institute for the Advancement of Technical Education.
Strona 222 - But whether elastic fluids do really consist of particles so repelling each other, is a physical question. We have here demonstrated mathematically the property of fluids consisting of particles of this kind, that hence philosophers may take occasion to discuss the question...
Strona 135 - As stated in the charter, it was intended "to give the highest specialized instruction and to provide the fullest equipment for the most advanced training and research in various branches of science, especially in its application to industry.
Strona 268 - ... interstate commerce if they do not contain more than 300 milligrams of tin per kilogram, or salts of tin equivalent thereto. When the amount of tin, or an equivalent amount of salts of tin, is greater than 300 milligrams per kilogram, entry of such canned goods packed subsequently to January 1, 1911, will be refused, and if found in interstate commerce proper action will be taken. It is the opinion of the board that the trade will experience little hardship in adjusting itself to this condition,...
Strona 154 - ... concentration in the molten or liquid mother mass of the gases initially present, a concentration carried on to supersaturation, and to the liberation of part of this gas from the supersaturated layers ; and perhaps (b) in some cases, such as that of the solidification of steel ingots, the formation ot a gas from chemical reaction brought about by fall of temperature or by passage from the liquid to the solid state.
Strona 256 - Scholarship is not to facilitate ordinary collegiate studies, but to enable students, who have passed through a college curriculum or have been trained in industrial establishments, to conduct researches in the metallurgy of iron and steel and allied subjects, with the view of aiding its advance or its application to industry.
Strona 228 - The solution of rosin soap can then be run off, treated with acid, the rosin collected in any manner desired, dried, and weighed. A second washing of the soap with petroleum spirit is hardly necessary, as very little remains...
Strona 144 - Science (B.Sc.) and Doctor of Science (D.Sc.). Candidates for Degrees in Science, if not graduates (by examination) in Arts in one of the Universities of the United Kingdom or in a Colonial or Foreign University recognised for the purpose by the University Court, must pass a preliminary examination in (i) English ; (2) Latin, Greek, French, or German ; (3) Mathematics; (4) One of ' the languages Latin, Greek, French, German, Italian, not already taken under (2), or Dynamics.

Strona 181 - By means of the special pipette introduce carefully, drop by drop, into one of the 200 cc cylinders, exactly 16 mm. depth of the ink to be tested. The ink should be previously tested to determine a proper solvent for both base and dye. Alcohol is generally the solvent to use for rosin inks. It may be necessary to use other solvents, such as gasoline (bp, 50° to 60°), ether, benzol, etc.
