Low Pass Filters For Telemetering Applications

Description: With exacting requirements imposed upon the operation of the subchannel modulators used in the FM-FM telemetering system, it became necessary to obtain a filter suitable for use in conjunction with the subcarrier oscillators in order that the desired distortion level could be effectively maintained. This paper describes, both theoretically and practically, a filter which was found to satisfactorily fill the required specifications.

A Solvent Extraction Method for Neptunium (237) Analysis

Description: Technical report describing a rapid and quantitative radiochemical method for the analysis of neptunium (237). This method is based on the extraction of neptunium (IV) with thenoyl-trifluoracetone in xylene. Neptunium (237) is separated free from other alpha emitters and from non-radioactive interferences, and the method may be readily adapted to remote control. [From Abstract]
