(see also prerogative.)—crown of an anchor. the place where the arms are joined to the shank, and unite at the throat.—crown of a gale. its extreme violence.—in fortification, to crown is to effect a lodgment on the top of; thus, the besieger crowns the covered way when he occupies with his trenches the crest of the glacis.
- The point where the arms of an anchor join the shank. crown-and-anchor: board game, formerly popular with british naval ratings but now banned due to excessive gambling. crow’s nest: a platform or shelter for a lookout near the top of a mast. viking longships are believed to have carried crows in cages attached to their mastheads (see as the crow flies). later, when sailing ships began to carry lookouts in a tub strapped to their main masthead, this inevitably became known as the “crow’s nest.” whaling ships often carried a second smaller tub mounted even higher on an upper mast and called the “bird’s nest.”
- The angled edge of a diamond or other gemstone, located between the girdle plane and table (top).
- The area of a diamond above the girdle plane. it consists of the table and the crown facets below it.
- This is the upper portion or the top of a diamond from the girdle up.
- As used by the drilling and bit-setting industries in the united states, the portion of the bit inset or impregnated with diamonds formed by casting or pressure-molding and sintering processes; hence the steel bit blank to which the crown is attached is not considered part of the crown. 536427 o—60 3

Crown cover, английский
Ground area covered by a crown, as delimited by the vertical projection of its outermost perimeter (26).
Crown density, английский
Thickness, both spatially (depth) and in closeness of growth (compactness) of an individual crown as measured by its shade density. collectively, crown density should properly be termed canopy density, as distinct from canopy cover (26).

- A handmade glass of soda-lime composition, used for windows; manufactured in the early 19th century by a now-obsolete process in which a hollow sphere of glass was blown while still very soft, then spun to form a large, nearly flat circular disk. during the spinning process, ripple lines were formed in a pattern of concentric circles, with their center at the center of the spun disk; this central area was used in a bull’s eye window. also
