Title: Paal Bratland: Innovator in Gamma Densitometry

Introduction

Paal Bratland is a notable inventor based in Bergen, Norway. He has made significant contributions to the field of gamma densitometry, holding a total of 2 patents. His work focuses on enhancing the functionality and reliability of gamma densitometer windows.

Latest Patents

Bratland's latest patents include the development of a pre-stressed gamma densitometer window and its method of fabrication. This innovative window comprises a plate of non-metallic, preferably gamma transparent, material. The design features a metallic frame member fitted around the outer edge of the plate, which is adapted to pre-load the plate with a compressive stress. This stress is sufficiently high to ensure that the sum of the compressive, tensile, and shear stress components generated in the plate under high-pressure conditions remains compressive. The method of fabrication involves shrink fitting the metallic frame member around the outer edge of the plate at a specific shrink-fit temperature, allowing the frame to apply compressive stress to the plate at any temperature below this threshold.
