The deduction of a specific angular value from the apparent angle, as
indicated by the plane of the etch line in an acid-survey bottle, to
correct for capillarity effects and thereby determine the true inclination
angle of a borehole. Proper values to be deducted from the apparent angles
read on acid bottles differing in size may be determined by referring to
charts, graphs, or tables prepared for that purpose.
See also:capillarity; capillarity-correction chart. Long
A chart, graph, or table from which the amount of capillarity correction
may be ascertained and applied to an angle reading taken from an acid-etch
line in an acid bottle of specific size to determine the true angle of
inclination of a borehole surveyed by the acid-etch method. Also called
correction chart; test-correction chart.

which it is in contact with a solid (such as in a lamp wick).

a. Dry-cell type. A self-contained light that permits free use of the
hands and may be suitable for gaseous or explosive atmospheres. The
headlamp, with focusing lens and bulb, is strapped to the head or hat, and
the dry cell battery unit can be clipped to the belt. To prevent
explosion, the bulb-socket ejects the bulb automatically in case of
breakage. Best, 1
b. Wet-cell type. With rechargeable, wet-cell cap lights, the battery is
worn on the belt, and the light unit, which is attached to the cap or
head, contains bulbs filled with krypton gas. The head light contains
either two separate bulbs or a single bulb with two filaments in parallel,
thus assuring the wearer of a constant source of light in the event that
one bulb or one filament burns out. Best, 1
A modification of the Ropp furnace for calcining sulfide ore. Fay
A length of safety fuse to which a blasting cap has been attached.
A package or cartridge of cap-sensitive explosive which is specif.
designed to transmit detonation to other explosives and which contains a
detonator.
A variety of quartz containing thin layers of clay. Fay

a. A piece of wood usually 24 to 36 in (60.96 to 91.44 cm) long, 6 to 8 in
(15.24 to 20.32 cm) wide, and 2 to 6 in (5.08 to 15.24 cm) thick, that is
fitted over a straight post or timber to afford more bearing surface for
the support. All single posts, or timbers including safety posts, should
be covered with a cap piece to provide additional bearing surface.
