TL;DR: In this paper, a flexible container is proposed for electronic packages where high voltages exist, and a simple, novel, weight-saving technique for accomplishing this consists essentially of replacing the conventional container with a flexible one (for example, fabric-reinforced rubber).
Abstract: In electronic packages where high voltages exist, a high dielectric strength environment surrounding the components is necessary. Liquid-filled units have used various oils which in addition to dielectric strength provide good thermal paths for cooling; evaporative-cooled units often use refrigerants. In either case allowance, volume-wise, must be made for thermal expansion of the fluid. A simple, novel, weight-saving technique for accomplishing this consists essentially of replacing the conventional container with a flexible one (for example, fabric-reinforced rubber). The flexible container then expands and contracts accomodating volume variations in the fluid. Design details, test results, and a general evaluation illustrating the adaptability of the flexible container as a practical design tool are discussed.

TL;DR: In this article, the authors proposed a method to determine speedily the temperature in the inner and outer conductors of coaxial line operating under any power, size and ambient conditions.
Abstract: The satisfactory performance of microwave transmission lines, operating under High power, largely depends on their capacity of maintaining the operating temperature below the specified limit. The method presented here will enable the mechanical as well as electrical engineer to determine speedily the temperature in the inner and outer conductors of coaxial line operating under any power, size and ambient conditions.
