Showing papers on "Bend radius published in 1972"
TL;DR: An attenuation of 7 dB/km has been achieved over kilometre lengths of liquid-core, multi-mode optical fiber waveguide as discussed by the authors, where the measured pulse dispersion depends on the mode distribution launched and on mode conversion which is a function of bend radius.

15 Mar 1972TL;DR: In a fiber reinforced composite blade as mentioned in this paper, the fibers are extended from the airfoil into the right and left side of the root to ensure that all fibers are wholly contained within the root and the minimum acceptable bend radius of the fibers is not violated.
Abstract: In a fiber reinforced composite blade, the fibers are extended from the airfoil into the right and left side of the root. It is carefully determined which fibers are extended into the left side and which are extended into the right side to assure that all the fibers are wholly contained within the root and the minimum acceptable bend radius of the fibers is not violated.

TL;DR: A sheet forming device and method capable of providing a hooked end on a sheet with one operation, the hook having a dual bend is described in this paper, where a movable forming bar enclamps the end portion of a sheet between the forming bar and a base, and a folding bar is actuatable to bend the end of the plate around the radius bend.
Abstract: A sheet forming device and method capable of providing a hooked end on a sheet with one operation, the hook having a dual bend. The device incorporates a movable forming bar which enclamps the end portion of a sheet between the forming bar and a base. The forming bar has a radius bend lip projecting from it and a secondary angle die section spaced from the radius bend. The secondary angle die section overlies a urethane insert in the base. The urethane is displaced by the pressure of the forming bar against the plate sufficient to force the plate to conform with the die surface of the forming bar. A folding bar is actuatable to bend the end of the plate around the radius bend.
