TL;DR: A method of fabricating individualized electron shields with openings corresponding to desired field shapes and sizes is discussed, and the effect of these shields on electron dosimetry is shown.
Abstract: A method of fabricating individualized electron shields with openings corresponding to desired field shapes and sizes is discussed. The electron shields are made from an alloy called Lipowitz' metal. These shields are designed to be mounted on any of six cone sizes provided with the Varian's Clinac 18 linear accelerator. The effect of these shields on electron dosimetry is shown.

TL;DR: A variable-density vehicle glare shield has a mount which supports at least two transparent shields so that they can be individually swung to and from a position in front of the eyes of a driver of the vehicle as discussed by the authors.
Abstract: A variable-density vehicle glare shield has a mount which supports at least two transparent shields so that they can be individually swung to and from a position in front of the eyes of a driver of the vehicle. The shields are of different colors, e.g. one yellow and one blue. Either shield can be used by itself, or both shields can be used together, thereby obtaining not only a different color for the composite shield made up of two overlying individual shields, but also permitting the driver to vary the shield-color density in accordance with prevailing light conditions.

TL;DR: In this article, the upper and lower magnetic shields were placed in the upper or lower tanks while shifting the faces at the end to eliminate concentration of leakage flux at split section, by locating the shields at the split section.
Abstract: PURPOSE: To eliminate concentration of leakage flux at split section, by locating upper and lower magnetic shields for upper and lower tanks while shifting the faces at the end. COPYRIGHT: (C)1979,JPO&Japio

TL;DR: In this article, overlapping joints have been measured to define joint characteristics that can be used for EMP shields and some non-ideal joints were measured to determine joint quality requirements.
Abstract: : Bolted, nonwelded joints in shields leak electromagnetic energy of frequencies above a few MHz. Overlapping joints have been measured to define joint characteristics that can be used for EMP shields. Also some nonideal joints were measured to determine joint quality requirements. (Author)

TL;DR: In this paper, a slit at an end of a magnetic flux intrude from windings was proposed to facilitate the mounting of magnetic shields to a tank as well as to prevent local heating in the tank by the provision of a slit.
