Proceeding thus, we have a series of areas exhausting the parabolic segment.
A type of parabolic reflector now in use is shown in fig. 30.
The cylinder contains a parabolic mirror in the back, a series of glass strips in the front, and two "carbons" in the middle.
The two shapes in use are the triangular and the parabolic or balloon-shaped.
My next recollection is that of Brown, dark against the sky, describing a parabolic curve and alighting further up the line.
The parabolic mirror will reflect the star to a perfect focus.
The coefficient of velocity is determined directly by measuring the parabolic path of a horizontal jet.
They got him out of the parabolic curve and headed back down.
They can be reflected by plain sheets of metal, concentrated by parabolic reflectors, refracted by prisms, concentrated by lenses.
For what are the circumstances of the parabolic representation?
