Page 192 - Reissue of THE ART OF DYEING WOOL, SILK AND COTTON. Translated from the French of M. HELLOT, M. MACQUER and M. LE PILEUR D'APLIGNY. First Published in English in 1789. Six Plates. Demy 8vo. 446 pp.
Page 212 - ... of coal per square foot of grate per hour. For smaller values the combustion is more perfect, but the large chimney loss, due to the large amount of air supplied, more than makes up for this. For higher rates the chimney loss gets less, but imperfect combustion and dust blown out of the fire does away with the advantage. The temperature of the waste gases naturally depends on the length of the flues through which they pass, and in Figs. 3 and 4 the author has plotted these temperatures and the...
Page 83 - If we had been dealing with a hollow sphere, we should have had two more boundary conditions, and these are replaced in the present case by the condition that e must be finite at the centre. SOLUTION OF THE EQUATIONS. We can get no further without assuming an expression for p; and to get a numerical result, we must assume a value for n. Since it is generally asserted that the rigidity of the earth is about the same as that of steel, I shall give n the value of 8x io8 grams per square centimetre,...
Page 37 - TJnin., etc., without re-grinding the cutter. The cutters were never at any time blunt, as the duration of each trial was about ten minutes after it began to take its full feed, and the speed maintained at ten revolutions per minute for all sizes of cutters. In all the trials on steel a stream of water played upon the cutter, but in the tests on cast iron no lubricant of any kind was used. In order to obtain a measure of the bluntness of the cutter, or resistance to penetration, observations of the...
Page 58 - Time in minutes. FIG. 2. water, represents the viscosity. The viscosimeter was always surrounded by a water-jacket kept at i6°C., and the test repeated until two results were obtained which agreed. The results are given in the table on the next page. The results obtained with wheat, rice, and maize starches were fairly concordant, and show a gradual increase in viscosity with the time of heating, up to a maximum, after which there appears to be a decrease. Potato starch gave very viscous solutions,...
Page 134 - ALLOWABLE VARIATIONS FROM CONTRACT SPECIFICATIONS Width. — The width shall not vary anywhere by more than ^ of an inch below the stipulated width nor more than % of an inch above. The width shall not be uniformly less than the stipulated width, but must, in a majority of places in each piece, be equal to, or greater than, the stipulated width. Goods shall be measured at right angles to the selvages when laid open on a flat horizontal surface and smoothed out by hand, but not stretched.
Page 3 - Whitworth, and Co., of Manchester, for their generosity in giving free of charge all tools and materials used in these experiments. The tool dynamometer used in the lathe tool experiments was designed by Dr. JT Nicolson, and is described by him in a paper read before the Institution of Mechanical Engineers in 1904. In this dynamometer the tool is held in the rest in such a manner as to allow of a movement in the direction of the axis of the lathe in a horizontal plane, and also two movements at right...
Page 180 - I have heard say that the chief trade of Coventry was heretofore in making of blue thread, and then the town was rich even upon that trade in manner only, and now our thread comes all from beyond sea. Wherefore that trade of Coventry is decayed, and thereby the town likewise.

(3) Upon the temperature of the surface of the tool in contact with the heel of the shaving, ie, where the tool is hottest: With the object of obtaining some idea of the rate of rise in temperature with cutting speed and depth of cut, a...
