pass,

opening or way by which a natural or artificial barrier can be crossed. The term pass is usually applied to a relatively narrow passage through a mountainous region. A pass, like an isthmus, may have great strategic and economic importance; the history of a nation has often been determined by its success or failure in defending a pass, and land trade routes must necessarily cross passes.

Pass

 

a gap formed by the grooves of two coupled rolls through which the metal to be reduced is passed in order to give it the required shape.

A distinction is made between reducing, roughing, and finishing passes. Reducing passes serve to reduce the cross section of the initial stock without significant alteration of its shape; roughing passes are used to produce rolled metal with a cross section close to that of the finishing stage; and finishing passes are used to give the metal its final shape and dimensions.
