Страница 2202 - A machine rock drill should be simple in construction, and strong in every part. 2. It should consist of few parts, and especially of few moving parts. 3. It should be as light in weight as can be made consistent with the first condition. 4. It should occupy but little space. 5. The striking part should be relatively of great weight, and should strike the rock directly. 6. No other part than the piston should be exposed to violent shocks. 7. The piston should be capable of working with a variable...
Страница 2570 - An examination of some of the heating curves will perhaps give the erroneous impression that Ac2 is an evolution rather than an absorption of heat. The swing back at the maximum is very abrupt following what appears to be a gradual building up of this maximum from an indeterminate low temperature.

Страница 2622 - The same two units haul the 1,400 ton train against the 1.1 grade at 17.5 miles per hour. The passenger locomotives are the same design as the freight locomotives except that they are geared for a maximum speed of 45 miles per hour on tangent level track. The average passenger train is composed of one locomotive unit and three standard passenger coaches. The general design of the locomotives is of the articulated double truck type, all weight being on the drivers.
