Fourteen dynamometer tests were performed on a B.F. Goodrich 2-727 brake assembly to investigate the characteristics inherent in modern brake design which are considered as indicators for brake induced landing gear strut chatter. The tests were designed to simulate normal service conditions experienced by the brake as part of the USAF T-38A aircraft system. Data from nine simulated landing roll tests and five simulated taxi tests were used to determine the slopes of the instantaneous coefficient of kinetic friction versus relative rubbing velocity curves for 10 ft/sec squared, 8 ft/sec squared, and 6 ft/sec squared deceleration conditions.

The purpose of the study was to conduct a validation test on a temperature indicator designed primarily for use in shipping whole blood. The indicator was developed by Artech Corporation, 2816 Fallfax Drive, Falls Church, Virginia 22042. Type 'A' and 'B' temperature indicators were activated in 5C temperature and attached to blood bags filled with 512.5 ml of water. A constant temperature water bath provided the testing medium. The temperature was monitored by a Yellow Springs scanning tele-thermometer. Results show that type 'A' indicator, designed to indicate in the range of 8-13C rendered an efficiency of 37%. The type 'B' indicator, designed to indicate in the temperature range of 10-15C, was 22% efficient. In the hands of the contractor they were 98% reliable. Further work is necessary to determine the reason for the discrepancy. (Author)

Military blood bank experiences are reviewed, especially the highlights encountered in the period 1941-1971 during World War II, Korean and Vietnam campaigns. The activation, including staff study and growth of the Blood Transfusion Division and The Blood Bank Center of the US Army Medical Research Laboratory, Fort Knox, Kentucky, is used as an example of planning for large- scale blood banking in the military (operations, training, and research) and, consequently, civil disaster blood bank planning. Large-scale blood bank operations in being at Fort Knox are illustrated and described. The growth and rapid expansion at Fort Knox paralleled the Vietnam campaign in both timing and activity., Library of Congress Catalog Card No. 78-184862.
