The operating rope for the blade front of a scraper. Hammond
That part of a panel wall between the windowsill and the support of the
panel wall. ACSG, 1

Standard, 2
b. Noncombustible. Webster 3rd
A letter name specifying the dimensions of bits, core barrels, and drill
rods in the A-size and Q-series wireline diamond drilling system having a
core diameter of 27 mm and a hole diameter of 48 mm. Cumming, 2
Ammonia water; esp., a solution of ammonia containing 10% ammonia by
weight.
A very corrosive, fuming, yellow liquid made by mixing nitric and
hydrochloric acids, usually in the proportion of one part by volume of
pure nitric acid with three parts by volume of pure hydrochloric acid.
Used in dissolving metals such as gold and platinum and in etching.
Syn:nitrohydrochloric acid; nitromuriatic acid.
A test conducted by detonating a standard quantity of explosives under
water and measuring both the detonation and gas pressures using
transducers; useful for evaluating the relative strengths of various
explosives. Du Pont, 2
a. Of, or pertaining to, water. AGI
b. Made from, with, or by means of water; e.g., aqueous solutions.
AGI
c. Produced by the action of water; e.g., aqueous sediments. AGI
Melting in the presence of water, as a magma. AGI
In the ion-exchange (IX) process, the feed to the exchange columns. In
solvent extraction, the aqueous feed containing the metal values to be
extracted into the organic phase.
A body of relatively impermeable rock that is capable of absorbing water
slowly but does not transmit it rapidly enough to supply a well or spring.
CF:confining bed
a. A formation, a group of ions, or a part of a formation that is water
bearing. AGI
b. A stratum or zone below the surface of the Earth capable of producing
water, as from a well. AGI
c. An underground stratum that will yield water in sufficient quantity to
be of value as a source of supply. An aquifer is not a stratum that merely
contains water, for this would apply to all strata in the ground-water
area. An aquifier must yield water. See also:aquitard
Carson, 1
In situ procedure, such as single-well (bail test or slug test) and
multiple-well pumping tests, used to determine hydraulic properties of an
aquifer. Freeze
a. Suggested by Bedier, as the opposite of aquifer. AGI
b. A rock that contains no interconnected openings or interstices and
therefore neither absorbs nor transmits water. CF:confining bed
AGI
Low-permeability bed, in a stratigraphic sequence, of sufficient
permeability to allow movement of contaminants, and to be relevant to
regional ground-water flow, but of insufficient permeability for the
economic production of water. See also:aquifer; aquiclude.
CF:confining bed
a. An orthorhombic mineral, 4[CaCO3 ] ; acicular, pyramidal,
tabular, reniform, columnar, or stalactitic habit; formed from hot
carbonated water in springs, cavities in basalt, or biogenetically in
shells and pearls (mother of pearl). Syn:aragon spar
b. The mineral group aragonite, cerussite, strontianite, and witherite.
Sand-size grains of predominantly aragonite (CaCO3 ) found in
shallow, tropical waters. Aragonite forms by chemical precipitation in sea
water due to the presence of SO4 ions.
Former name for aragonite.
A triclinic mineral, Ag(Sb,Bi)S2 ; iron black with perfect
cleavage; at Chocaya, Bolivia.
An operation that involves a purchase in one market with the simultaneous
sale of an equivalent quantity in another market, (e.g., the London Metal
Exchange and the New York Commodity Exchange), and the necessary foreign
exchange transaction to protect against any change in the parities between
the two currencies involved. Wolff
Applied to minerals having a treelike form, esp. when fairly massive. If
the mineral formation is so thin as to resemble a painting of a tree, it
is generally called dendritic. Syn:dendriform; dendritic. Fay
