Diamond wire drawing die blanks and methods of making the same

Abstract: A diamond wire drawing die blank and method for making the same are provided in which a diamond die blank is formed by metering about one half of a metal powder required to form a shroud around a diamond into a die cavity, partially compressing said one half while forming a central conical depression in said powder, placing a diamond in the formed conical cavity, adding the remaining metal powder to the mold over the die and first compressed half, compressing the metal powder around the diamond and sintering said powder compact

Methods To Recover Cesium Or Rubidium From Secondary Ore

Abstract: A method to recover cesium, rubidium, or both from secondary ore is described and involves using scans and sorting techniques. Refined secondary ore is further described.

Nonwoven fabric-aerogel composite material containing two-component fibres, a method of producing said material and the use thereof

Abstract: The invention concerns a composite material comprising at least one layer of nonwoven fabric and aerogel particles and characterised by the fact that the nonwoven fabric contains at least one two-component fibre material which has regions of low melting point and regions of high melting point, the fibres of the fabric being connected both to the aerogel particles and to one another via the low-melting point regions of the fibre material. The invention also concerns a process for producing the material and the use of it.

A Fiber-Based Laser Ultrasonic System for Remote Inspection of Limited Access Components

Abstract: Surface and plate waves are commonly used to nondestructively inspect the near-surface region of a solid component for cracks and other defects due to, for example, structural fatigue. One particularly attractive method of generating and detecting such ultrasonic signals is laser based ultrasonics (LBU) [1]. In particular, because it is non-contact (i.e., does not require couplant), LBU can be implemented for inspection of limited access components using optical fibers, requiring only a small cross-sectional area for access. An example can be found in the inspection of internal surfaces of an aircraft wing as shown in Figure 1 where a contact method would obviously be difficult to apply. Furthermore, in cases where extremely high sensitivity is required, bandwidth reduction can be employed by concentrating the laser generated signal into a narrow frequency band.
