| Title: | A Review of Automatic Radiometric Pyrometry | ||||
|---|---|---|---|---|---|
| Author: | Sumner Ackerman | ||||
| Abstract: | Optical and radiation pyrometers have been used extensively over the past several decades. As a result there is a great deal in the literature pertaining to their theory, design and application. The more recent pyrometers suitable for continuous measurements and control have simulated interest in the relative capabilities and limitations of the different types of pyrometers now available. The prime purpose of this paper is to review the more fundamental characteristics of the three major types pf automatic radiometric pyrometers, toward the end of helping to predict theory relative usefulness for different applications. It is anticipated that this material can aid, but will not necessarily be conclusive in the optimum choice of pyrometer because of the great number of technical as well as economic factors involved, the lack of adequate spectral emissive data for many materials, and particularly because of the anomalous behavior of target surfaces and transmission media that is frequently encountered in practice. | ||||

| Title: | Evaluation of the Fire-Detection and -Extinguishing Systems of the Navy XP6M-1 Airplane | ||||
|---|---|---|---|---|---|
| Author: | Joseph Osman | ||||
| Abstract: | This evaluation of the fire-detection and extinguishing systems of the Navy XP6M-1 airplane was made using a steel mockup of the XPM6M-1 nacelle and dummy engine. The airflows for flight and surface-operating consultations were simulated doing tests. The fire detection system was evaluated by igniting small fires within the nacelle. The fire extinguishing system was evaluated by conducting quantity and rate measurement tests, by measuring extinguishing agent concentration during discharge of the system, and by full-scale fire extinguishing tests. The original continuous detector system, with elements mounted circumferentially was found to be ineffective in detecting test fires in the lower half of the nacelle; however a continuous system, with its elements mounted longitudinally in the lower portion of the nacelle proved to be effective in alarming these same test fires. Results of the valuation tests of the fire extinguishing system indicated that the system provided rapid discharge of agent, but its effectiveness in extinguishing fires was found to be marginal. |

| Title: | Aircraft Installation and Operation of an Extinguishing-Agent Concentration Recorder | ||||
|---|---|---|---|---|---|
| Author: | James E. Demaree & Paul R. Dierdorf | ||||
| Abstract: | This report covers the utilization of a gas-analyzing instrument for evaluating aircraft fire-extinguishing systems. This instrument records the extinguishing-agent air concentration resulting when the extinguishing system is discharged, and thereby provides a means of evaluating the aircraft extinguishing system under actual flight conditions. This report is intended to serve as an instruction manual for installation and operation of the instrument. Calibration data based on available information to aid in the reduction and interpretation of the test date obtained also are included. The instrument and the principles of operation are described briefly. |

| Title: | Thermocouple And Thermocouple Extension Wires | ||||
|---|---|---|---|---|---|
| Author: | Instrument Society of America | ||||
| Abstract: | This recommended practice applies to thermocouples and extension wires for industrial use. Its purpose is to establish uniformity in the designation of various types of thermocouples and extension wires and to provide, by means of the color of its insulation, an identification of its type of composition as well as is polarity when used as part of a thermocouple system | ||||
