[Letter from Matilda Dodd to Mr. Moore and Sis, August 31, 1879]

Description: She was glad to hear that the Moore's were doing well and mentions they are doing well also. The weather is still warm, but they are expecting more rain after a thunderstorm last Saturday. They are plowing to sow wheat. The Christians have had preaching every night and Abe and Bettie went to Union to preach. Bob has made cider and sold $3 worth in town. They have apples falling and peaches that are ripe. Dinky and Bettie are going to can some apples. They have beans, tomatoes, sweet potatoes in abundance and the late irish potatoes look good. She gives information on Faunt, that he is a good guy and has two brothers. She asks that they write back soon.

[Letter from Charles B. Moore to Henry S. Moore, August 31, 1885]

Description: This is a letter from the Charles B. Moore Collection. It is written by Charles B. Moore to his brother Henry S. Moore. In his letter, Charles updates his brother on the happenings of his trip, who he has visited, and how he enjoys seeing old friends again. He details news about a trip that Betty Thornhill is making to Dallas and he states that she may be visiting him soon, if she is not already there. He notes that the family listened to a sermon by Brother Haynes. All the family attended this sermon except Mr. Dodd. He mentioned that Henry should pass this information on to Mrs. Thornhill. Moore tells his brother about meeting new friends and old comrades as well as their siblings, but also details the business successes of family friends. He states that Sam Thornhill and Tom And Alice Wright have plans to visit Texas soon. He expresses his happiness for John Stewart who has been appointed revenue collector and will make good pay; a living which will prevent him from having to turn to hard labor for money. He details that Tim Thornhill was very badly injured from a buggy accident and mentions a robbery which occurred to a family friend as well as financial concerns surrounding this crime. He states that he has seen Alexander and Allen, but has not spoken to them about the estate of their uncle. Charles tells Henry that Jack Wood's daughter will be married and Tobe and Florence want him to accompany them to the wedding. He updates Henry on the weather and on the crops in the Gallatin area. He notes that Sally Thornhill is recovering from her illness and details additional news concerning family friends and the community. He mentions his past plans with friends and …

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.

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.

Correlation of cylinder-head temperatures and coolant heat rejections of a multicylinder, liquid-cooled engine of 1710-cubic-inch displacement

Description: "Data obtained from an extensive investigation of the cooling characteristics of four multicylinder, liquid-cooled engines have been analyzed and a correlation of both the cylinder-head temperatures and the coolant heat rejections with the primary engine and coolant variables was obtained. The method of correlation was previously developed by the NACA from an analysis of the cooling processes involved in a liquid-cooled-engine cylinder and is based on the theory of nonboiling, forced-convection heat transfer. The data correlated included engine power outputs from 275 to 1860 brake horsepower; coolant flows from 50 to 320 gallons per minute; coolants varying in composition from 100 percent water to 97 percent ethylene glycol and 3 percent water; and ranges of engine speed, manifold pressure, carburetor-air temperature, fuel-air ratio, exhaust-gas pressure, ignition timing, and coolant temperature" (p. 207).

Experimental Investigation of the Effects of Sweepback on the Flutter of a Uniform Cantilever Wing With a Variably Located Concentrated Mass

Description: Report presenting data from 95 subsonic flutter tests conducted in the flutter research tunnel on untapered cantilever wings with sweepback angles of 0, 45, and 60 degrees and carrying a single concentrated weight. The primary purpose of the investigation was to present experimental information to be used to evaluate analytical procedures for determining the flutter speed of weighted sweptback wings. The dynamic pressure, flutter velocity, Mach number, natural and flutter frequencies, and phase-angle relationships of the stresses for the natural and flutter frequencies are presented.

Flight Investigation at High-Subsonic, Transonic, and Supersonic Speeds to Determine Zero-Lift Drag of Bodies of Revolution Having Fineness Ratio of 6.04 and Varying Positions of Maximum Diameter

Description: Report presenting a flight investigation of rocket-powered models at high-subsonic, transonic, and supersonic speeds to determine the zero-lift drag of fin-stabilized bodies of revolution differing in maximum diameter. All bodies had 6.04 fineness ratio and cut-off sterns with equal base area. The most favorable location out of the 20-percent, 40-percent, and 60-percent positions were evaluated for different speeds.

Investigation of Fretting by Microscopic Observation

Description: "An experimental investigation, using microscopic observation and color motion photomicrographs of the action, was conducted to determine the cause of fretting. Glass and other noncorrosive materials, as well as metals, were used as specimens. A very simple apparatus vibrated convex surfaces in contact with stationary flat surfaces at frequencies of 120 cycles or less than l cycle per second, an amplitude of 0.0001 inch, and load of 0.2 pound" (p. 135).

A radar method of calibrating airspeed installations on airplanes in maneuvers at high altitudes and at transonic and supersonic speeds

Description: A method of calibrating the static-pressure source of a pitot static airspeed installation on an airplane in level flight, dives, and other maneuvers at high altitude and at transonic and supersonic speeds is described. The method principally involves the use of radar-phototheodolite tracking equipment. The various sources of error in the method are discussed and sample calibrations are included.
