Grain tin is made by allowing the molten metal to fall from a height on to a hard
cold surface. To produce what is known as common tin, the metal passes at once
to the moulds. Refined tin is the result of using better ores and lengthening the ...

The poling of copper consists in plunging the end of a pole of green wood,
preferably birch, beneath the surface of the molten metal, and stirring the mass
with it. Violent ebullition takes place, large quantities of gases are liberated, and
the ...

The success of the process, as in tinning metals, depends on the thoroughness
with which the metal is cleansed previous to being passed through the molten
zinc. The plates or vessels are first immersed in a warm bath of equal parts of ...

Side 5 - When a straight line standing on another straight line makes the adjacent angles equal to one another, each of the angles is called a right angle ; and the straight line which stands on the other is called a perpendicular to it.
Side 21 - AB of the circle into as many equal parts as the polygon is to have sides. With the points A and B as centers and radius AB, describe arcs cutting each other at C.
Side 224 - To find the pressure in pounds per square inch of a column of water, multiply the height of the column in feet by .434. Approximately, we say that every foot elevation is equal to % Ib. pressure per square inch ; this allows for ordinary friction. To find the diameter of a pump cylinder...
Side 227 - To find the velocity in feet per minute necessary to discharge a given volume of water in a given time, multiply the number of cubic feet of water by 144 and divide the product by the area of the pipe in inches.

Side 10 - A circle is a plane figure contained by one line, which is called the circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference are equal to one another : 16. And this point is called the centre of the circle.
Side 5 - A plane angle is the inclination of two lines to one another in a plane, which meet together, but are not in the same direction.
Side 5 - A straight line is that which lies evenly between its extreme points.
Side 15 - A cone is a solid figure described by the revolution of a right-angled triangle about one of the sides containing the right angle, which side remains fixed.
