Report of the daily cash position for Sugarland State Bank.

Report presenting an investigation in the supersonic pressure tunnel at Mach number 2.01 to study the wake patterns in the lee of bodies at high angles of attack. The configurations tested consisted of two cylindrical body shapes, one circular and one elliptical in cross section, with a fineness-ratio-3.5 ogival nose and a fineness-ratio-6 conical nose. Results regarding vapor-screen photographs, wake characteristics, wake patterns, wake characteristics, and testing with transition strips are included.

Report presenting a determination of the landing contact conditions of the Boeing B-47 airplane using a specially built motion picture camera. A statistical analysis of the sinking speeds and horizontal speeds was carried out on the photographs.

"An investigation to determine the static longitudinal and lateral stability characteristics of a 1/62-scale model of the Bell X-1A has been conducted in the Langley 9-inch supersonic tunnel. tests were made at Mach numbers of 1.62, 1.94, 2.22, 2.40, and 2.62 on the wing-body, wing-body-vertical-tail, and complete configurations. Data are presented for both the body and stability axes. Detailed analysis of the test results is omitted" (p. 1).

Report discussing an investigation of the performance of a three-stage transonic compressor with high stage pressure ratios to investigate problems encountered when high-pressure-ratio transonic stages are grouped together to form a multistage compressor. Results are presented regarding overall performance in Freon, stage performance, and radial variation in overall stagnation pressure ratio.

Memorandum presenting a theoretical analysis of a cruciform missile configuration equipped with floating controls to determine if such controls can be utilized to improve the airframe transient response characteristics.The investigation covers either forward or aft locations of the floating controls at supersonic speeds. The results indicate that a substantial increase in airframe damping can be obtained through a proper selection of hinge-moment coefficients and through the use of a fixed-rate viscous damper attached to the floating-control surfaces.

Report presenting the aerodynamic loads acting over the vertical tail, which were determined during an investigation of the lateral stability and control characteristics of the Convair XF-92A. Results regarding the vertical-tail panel characteristics, vertical-tail load parameters, and vertical-tail bending and normal-force coefficients are provided.

Memorandum presenting an investigation of a low-speed leading-edge chord extension in the 19-foot pressure tunnel. Chord-extensions of various geometric designs were tested on three 45 degree sweptback wings of aspect ratio 5 and taper ratio 0.28 incorporating different airfoil sections. The data indicated that leading-edge chord-extensions could be used to produce large reductions in the longitudinal instability of all three wings tested.

The preparation, purification, and chemical properties of THP have been reviewed with emphasis on the hydrolytic reactions. TBP is chemically a very stable compound as evidenced by its thermal stability and resistance to oxidation. The most important reactions are hydrolytic which cleave the butyl or butoxy group and normally produce butyl alcohol together with dibutyl and monobutyl phosphate (DBP and MBP, respectively), and eventually H/sub 3/PO/sub 4/. Hydrolysis occurs in either the organic phase or the aqueous phase and is first order with respect to the ester. Although the rate in the aqueous phase is much faster than in the organic phase, the solubility is so low in aqueous solutions that the organic phase reactions become more important. Acid hydrolysis depends on both the nature of the acid and the concentration. The order with respect to acid concentration is close to one but often less than one. Hydrolysis is catalyzed by both acids and bases. In the latter case, the reaction occurs only in the aqueous phase and normally stops with the formation of dibutyl phosphate. The hydrolysis rate increases greatly as the temperature is raised and an activation energy of the order of 20 kcal is often found. The …

The capital and direct and indirect operating costs were estimated for erecting and operating mills of 220 and 440 tons of ore per day capacity. The ores considered contained 0.15 or 0.30% uranium. The processes considered included crushing, grinding, acid or carbonate leaching, and final recovery of the U/sub 3/O/sub 8/ in a Higgins ion exchange contuctor with a 5 M NaCl, 1 M NaCl, 1 M NH/sub 4/NC/sub 3/, or 1 M cost estimate have been given due and careful consideration with reference to requirements for a mill of this type. Further detailed information with reference to the construction and operation characteristics of the Higgins ion exchange contactor are given in ORNL reports 1907 and 1918. (auth)
