SIGHTS, the name for mechanical appliances for directing the axis of the bore of a gun or other firearm on a point whose position relative to the target fired at is such that the projectile will strike the target.
Taylor bag filters are generally used for clearing the melted liquor of its mechanical impurities.
Often, listening to the pilgrims' tales, she was so stimulated by their simple speech, mechanical to them but to her so full of deep meaning, that several times she was on the point of abandoning everything and running away from home.
The mechanical properties of the cycloid were investigated by Christiaan Huygens, who proved the curve to be tautochronous.
In some cases, as when heat is converted into the kinetic energy of moving machinery or the potential energy of raised weights, there is an ascent of energy from the less available form of heat to the more available form of mechanical energy, but in all cases this is accompanied by the transfer of other heat from a body at a high temperature to one at a lower temperature, thus losing availability to an extent that more than compensates for the rise.
It is scarcely possible to imagine a higher effort of hand and eve than this nunome-zOgan displays, for while intricacy and elaborateness are carried to the very extreme, absolute mechanical accuracy is obtained.
Reverberatory furnaces of three types are employed in calcining copper ores: (I) fixed furnaces, with either hand or mechanical rabbling; (2) furnaces with movable beds; (3) furnaces with rotating working chambers.
The peasants are described as intelligent, and the artizans are justly celebrated for their ingenuity and mechanical skill.
The first really successful mechanical pyrites-burner was constructed many years ago by MacDougall Bros.
The burner gas is introduced at one end, the waste gases issue from the other, the movement of the gases being impelled partly by their own chemical reactions, partly by the draught produced by a chimney (or tower), or by mechanical means.
