Bitumen
(gcide) | Bitumen \Bi*tu"men\, n. [L. bitumen: cf. F. bitume. Cf.
B['e]ton.]
1. Mineral pitch; a black, tarry substance, burning with a
bright flame; Jew's pitch. It occurs as an abundant
natural product in many places, as on the shores of the
Dead and Caspian Seas. It is used in cements, in the
construction of pavements, etc. See Asphalt.
[1913 Webster]
2. By extension, any one of the natural hydrocarbons,
including the hard, solid, brittle varieties called
asphalt, the semisolid maltha and mineral tars, the oily
petroleums, and even the light, volatile naphthas.

Bitumen process
(gcide) | Bitumen process \Bi*tu"men proc"ess\ (Photog.)
Any process in which advantage is taken of the fact that
prepared bitumen is rendered insoluble by exposure to light,
as in photolithography.

Elastic bitumen
(gcide) | Elastic \E*las"tic\ ([-e]*l[a^]s"t[i^]k), a. [Formed fr. Gr.
'elay`nein to drive; prob. akin to L. alacer lively, brisk,
and E. alacrity: cf. F. ['e]lastique.]
1. Springing back; having a power or inherent property of
returning to the form from which a substance is bent,
drawn, pressed, or twisted; springy; having the power of
rebounding; as, a bow is elastic; the air is elastic;
India rubber is elastic.
[1913 Webster]
Capable of being drawn out by force like a piece of
elastic gum, and by its own elasticity returning,
when the force is removed, to its former position.
--Paley.
[1913 Webster]
2. Able to return quickly to a former state or condition,
after being depressed or overtaxed; having power to
recover easily from shocks and trials; as, elastic
spirits; an elastic constitution.
[1913 Webster]
Elastic bitumen. (Min.) See Elaterite.
Elastic curve.
(a) (Geom.) The curve made by a thin elastic rod fixed
horizontally at one end and loaded at the other.
(b) (Mech.) The figure assumed by the longitudinal axis of
an originally straight bar under any system of bending
forces. --Rankine.
Elastic fluids, those which have the property of expanding
in all directions on the removal of external pressure, as
the air, steam, and other gases and vapors.
Elastic limit (Mech.), the limit of distortion, by bending,
stretching, etc., that a body can undergo and yet return
to its original form when relieved from stress; also, the
unit force or stress required to produce this distortion.
Within the elastic limit the distortion is directly
proportional to the stress producing it.
Elastic tissue (Anat.), a variety of connective tissue
consisting of a network of slender and very elastic fibers
which are but slightly affected by acids or alkalies.
Gum elastic, caoutchouc.
[1913 Webster]Elaterite \El"a*ter*ite\, n. (Min.)
A mineral resin, of a blackish brown color, occurring in
soft, flexible masses; -- called also mineral caoutchouc,
and elastic bitumen.
