Page 216 - Figs. 13 and 14 show the construction of a ball mill. It consists of a drum filled with steel balls. The drum is lined first with steel plates, (d) which lap one over the other to form steps. As the drum revolves, the balls drop over the steps pounding the material to pieces. The partially ground material then drops through holes in the plates on to perforated steel screens (g) bolted around Fig.

Page 306 - Another characteristic of the aluminum cell is the dissolution of a part of the film when the plates stand in the electrolyte and the cell is disconnected from the circuit. The film is composed of two parts; one part is hard and insoluble, and apparently acts as a skeleton to hold the more soluble part. The action of the cell seems to indicate that the soluble part of the film is composed of gases in a liquid form. When a cell which has stood for some time disconnected, is re-connected to the circuit,...

There is something so audacious in the conception of ice-cream, that it is not strange that a population undebauched by the luxury of great cities looks upon it with a kind of awe and speaks of it with a certain emotion.

The spindle, therefore, has a gyratory motion, and may or may not rotate on its own axis. As the head, running eccentrically, approaches and recedes from the sides of the hopper, the stone is gradually crushed and falls down between the crushing surfaces. The stone must be broken by hand to a convenient size to feed into the hopper. A crusher having a hopper...
Page 136 - In this regard, the acceleration is directly proportional to the square of the velocity and inversely proportional to the radius of the turn. By common usage, where the axis of rotation is external to the body, as in an aircraft turn or a centrifuge, the acceleration is frequently termed "radial" acceleration, while the term "angular" is better retained for situations where the axis of rotation passes through the body.
