PAR Loop Schedule Review

Description: The schedule for the installation of the PAR slurry loop experiment in the South Facility of the ORR has been reviewed and revised. The design, fabrication, and installation is approximately two weeks behind schedule at this time due to many factors; however, indications are that this time can be made up. Design is estimated to be 56 per cent complete, fabrication 27 per cent complete-and installation 11 per cent complete:

Aircraft Power-Plant Instruments

Description: From Summary: "The report includes a description of the commonly used types and some others, the underlying principle utilized in the design, and some design data. The inherent errors of the instrument, the methods of making laboratory tests, descriptions of the test apparatus, and data in considerable detail in the performance of commonly used instruments are presented. Standard instruments and, in cases where it appears to be of interest, those used as secondary standards are described."

Wing pressure distribution and rotor-blade motion of an autogiro as determined in flight

Description: From Summary: "This report presents the results of tests in which the pressure distribution over the fixed wing of an autogiro was determined in both steady and accelerated flight. In the steady-flight condition, the rotor-blade motion was also measured. These data show that in steady flight the rotor speed as a function of the air speed is largely affected by the variation of the division of load between the rotor and the wing; as the load on the wing increases, the rotor speed decreases."

Wind-Tunnel Investigation of an N.A.C.A. 23012 Airfoil with a Slotted Flap and Three Types of Auxiliary Flap

Description: An investigation was made in the N.A.C.A. 7- by 10-foot wind tunnel to determine the aerodynamic section characteristics of an N.A.C.A. 23012 airfoil with a single main slotted flap equipped successively with auxiliary flaps of the plain, split, and slotted types. A test installation was used in which an airfoil of 7-foot span was mounted vertically between the upper and the lower sides of the closed test section so that two-dimensional flow was approximated" (p. 699).

H.E.W. - 300 Area - Metal turnings - Fire hazard

Description: This memorandum discusses means to extinguish magnesium fires in metal turnings at the Hanford Engineer Works 300 Area. The storage of metal turnings in 55 gallon drums presented a fire hazard, for which an effective means for extinguishing the fire had not been presented. This memorandum is dated July 1943. (JL)

Distribution Coefficient of D₂O Between Triethylamine and Water

Description: Summary: "Water containing 1.8% D2O was distributed between the two liquid phases formed with triethylamine at 20 and 35 C. The triethylamine was removed from each phase by aseotropic distillation with benzene before analyzing the water by determining its density with a quartz float. The ratios of the concentrations of the D2O in the water layer to that in the amino layer were 1.007 and 1.004 at 20 and 35, respectfully. The differences from unity are about the same as the errors of analysis."

Classified information required by operators and others exposed to radiation hazards

Description: Information required by operators exposed to radiation hazards is discussed. All areas of the plant are subjected to radiation hazards similar to those in the radium industry. Personnel in these areas are required to wear pencil meters and special badges that are evidently not solely for identification. They are required to submit to medical examinations more stringent and frequent than usual. They are required to wear heavy gloves in one location, thin gloves in another, disposable hats or rubbers in another. They are required to stay away from familiar objects that they could handle a few days before. They observe health instrument men making readings at points not tangibly influenced by the operations. Under these circumstances, operators cannot perform their duties intelligently without being advised of the general nature of the risks involved. Since the general beta and gamma hazard occurs at nearly all points and cannot reasonably be concealed, this is the feature selected for general information. The special hazard of 105 Building can then be concealed, and the origin, but not the nature of the hazard in 231 likewise concealed.

Corrosion of Tuballoy-Molybdenum Alloys by Water

Description: The primary purpose of the corrosion work was to find a tuballoy alloy which would be sufficiently corrosion resistant to be useful for canned slugs even if some of the can were to leak. The secondary purpose was to obtain general corrosion data on tuballoy alloys.

A method of analysis of V-G records from transport operations

Description: A method has been developed for interpreting v-g records taken during the course of commercial transport operation. This method involves the utilization of fairly simple statistical procedures to obtain "flight envelopes," which predict that, on the average, in a stated number of flight hours, one value of airspeed will exceed the envelope, and one positive and one negative acceleration increment will exceed the envelope with equal probability of being experienced at any airspeed. Comparison with the actual data obtained from various airplanes and from various airlines indicates that these envelopes predict the occurrences of large values of acceleration and airspeed with a high degree of accuracy.
