Page 105 - At the top it is provided with a hook, G, the opening of which is slightly larger than the thickness of the spring. The piston is thus free to move laterally, and no binding action is possible between it and the sides of the bore, such as would occur if the piston were rigidly attached to the spring. The mirror, H, is clamped to a steel spindle, I, the ends of which are pivoted in small holes in the vertical spring cheeks, JJ.
Page 133 - Ampere, which is one-tenth of the unit of current of the CGS system of electromagnetic units and which is represented sufficiently well for practical use by the unvarying current which, when passed through a solution of nitrate of silver in water, in accordance with a certain specification, deposits silver at the rate of 0.001118 of a gramme per second.
Page 106 - The spring K, while sufficiently rigid to transmit the motion of the main spring to the end of the arm M without buckling, is flexible enough to allow for the angular motion of that arm. The mirror is thus turned about the axis of the spindle by an amount which is proportional to the displacement of the main spring D, and therefore to the pressure under the piston.
Page 96 - The second law: (1) it is impossible for a self-acting machine, unaided by any external agency, to convey heat from a body...
Page 349 - Unit, which is the l/180th part of the heat required to raise the temperature of 1 Ib. of water from 32° to 212° F.
Page 102 - For compressible flow this becomes: where y is the ratio of the specific heat at constant pressure to that at constant volume...
Page 93 - Unit is the quantity of heat required to raise the temperature of 1 Ib. of water through 1 °F.
Page 307 - A copper tube, closed at the lower end, projecting at an angle of 45° from the side of the bath, near the bottom, provides a means of heating the bath liquid, and by the use of a revolving agitator, which forms part of the apparatus, the heated liquid rising from the copper tube can be uniformly distributed through the bath. The agitator carries a thermometer to indicate the temperature of the bath. The...
Page 106 - The diagram traced by the spot is seen as a bright line of light. The screen is engraved with horizontal and vertical lines, on which the diagram is projected. The pressure at any point can thus be easily read off, or the diagram can be plotted down on squared paper. Three pistons are used, the areas being in the ratio of 1, 2 and 4. There are two springs, which are ground so that the stiffnesses are in the ratio of 1 to 5. A wide range of sensibility is thus obtained. The smaller pistons fit inside...
Page 305 - Through the lid a steel shaft passes, carrying on the top a small bevelled wheel, h, the bevel of which is milled, and on the lower part two sets of stirrers, one of which is below the surface of the oil, and the other in the vapour space above. A horizontal shaft carried on two standards terminates at one end in a bevelled wheel...
