This defect can be avoided (after Abbe) if a small central portion of the back surface of the front lens be ground away and blackened; this portion should exactly catch the direct cone of rays, whilst the edges of the lens let the deflected cone of rays pass through (fig.
Deflecting Force for Translation in a Curved Path.In machinery, deflecting force is supplied by the tenacity of some piece, such as a crank, which guides the deflected body in its curved path, and is unbalanced, being employed in producing deflexion, and not in balancing another force.
In order that the needle may project outside the guard tube, openings are made in its two sides; hence the moment the needle is deflected each half of it becomes unsymmetrically placed relatively to the two metallic pieces which join the upper and lower half of the guard tube.
The rainfall zones are, however, somewhat deflected from a due west-to-east direction, the drier northern conditions extending southwards along the east coast, and those of the south northwards along the west.
The belt buckle that deflected the knife from his heart was now irritating the scar.
He deflected and grabbed her.
In an actual observation the deflecting needle would be reversed, as well as the deflected one, while different weights would be used to deflect the needle b..
On reaching the South American coast, the southern equatorial current splits into two parts at Cape St Roque: one branch, the Brazil current, is deflected southwards and follows Currents.
As it approaches the Atlantic, the Orange, in its efforts to pierce the mountain barrier which guards the coast, is deflected north and then south, making a loop of fully 90 m., of which the two ends are but 38 m.
At Bellegarde the Valserine flows in (right), and then the river resumes its southerly direction, from which the great gorge had deflected it for a while.
