Laminated flat cables using Kapton film were fabricated; these cables withstood temperatures up to 1000 deg F (538 deg C) for 10 minutes and potentials as high as 20 to 30 kV dc. A superior polyimide adhesive, Thermostik-D', was originated in the Bendix Polymer Laboratory, and a moldable polyimide powder and a process for using it were developed. These materials exhibit electrical strengths up to 625 volts/mil (24 kV/mm) and temperature resistance as high as 850 deg F (454.4 deg C). (auth)

The U. S. Atomic Energy Commission conducted an airborne radioactivity survey of the Red River region of Texas and Oklahoma beginning in December 1955 and ending in May 1956. All or parts of Archer, Clay, and Montague Counties in northern Texas and Carter, Cotton, Jefferson, and Stephens Counties in southern Oklahoma were surveyed. Particular attention was paid to those areas where exposures are found of red beds of the Permian Wichita Group. Field examinations were conducted of anomalies discovered by airborne reconnaissance as well as those reported by private individuals. Forty localities were examined, the majority in sandstones, siltstones, or conglomerates. Uranium and copper minerals were identified at several localities. Ferruginous staining, bleaching of the sandstone color, calcium carbonate cement, and carbonized plant remains are common to the deposits
