Flat-panel displays poised to displace some CRT applications
Regardless of cogent arguments favoring CRTs, flat-panel displays can be expected to infringe on CRTs at an increasing pace, in areas that don't require the unique capabilities offered by shadow-mask CRTs.

Drop tests show annealing restores "abused" magnetic shields
A series of "drop" tests on five magnetic shield cylinders, under accurately controlled conditions, have proved that dropping a magnetic shield degrades its permeability and lowers the shielding effectiveness. But, re-annealing the degraded shield, restores optimum magnetic shielding properties.
