  "A Second Look at Man, Machine, and Automatic Test Operations."

  A summary found following the errata page reads: "This paper presents a second look at the subject of the man-machine relationship in automatic test operations. 'Man, Machine, and Automatic Test Operations' was presented by the writer at Battelle Memorial Institute in November of 1963...It is the purpose of this second look at the man-machine interface to pinpoint those concepts which have proven their worth with time and those concepts which have proven to be weak, and as a result modified with time." This paper was prepared by George F. Meister, Jr.

  "Capabilities and Limitations of Space Communication Systems."

  The paper "Capabilities and Limitations of Space Communication Systems" is part of a General Electric Technical Information Series prepared for the Apollo Support Department. The abstract states "A survey and study of the basic parameters of information transfer systems for space communications is presented in this paper, to familiarize systems checkout and on communication engineers with the state-of-the-art and trends in this field. Both current and anticipated requirements for space communication systems are briefly considered. Some of the problems that exist in space communication are presented, along with a general review of current communication systems, their capabilities, and limitations as well as possible improvements in the areas of spacecraft directional antennas, ground stations and antennas, spacecraft transmitter power, and telemetry systems. It is concluded that the increased capabilities expected by the end of this decade should make adequate and reliable space communication possible for most predicted communication needs of future space missions at lunar and near-planet ranges."

  "Carbon-Burning Nucleosynthesis at Constant Temperature."

  "Carbon-Burning Nucleosyntesis at Constant Temperature" is part of the Orange Aid preprint Series in Nuclear Astrophysics, August 1968. The abstract states "Syntesis of elements during thermonuclear burning of carbon is examined at a series of temperatures (T=0.6, 0.8, 1.0, 1.2, 1.4) and for several initial compositions. Recent eperimental results (Ptterson, Winkler, and Zaidins 1968) for the 12C+!@C reaction are used. A general method for numerical solution of nuclear-reaction networkds is described. At the higher temperatures in the range now thought to be appropriate for carbon burning in stars,

  "The Case for Compatibility."

  "The Case for Compatibility" is a paper by Robert L. Smith, Jr., who worked in Quality and Reliability Assurance Laboratory at George C. Marshall Space Flight Center. The summary states, "Ever since the use of missiles and space launch vehicles began, questions have existed in every program regarding the similarity between upstream (e.g., manufacturing, static firing ) and launch site checkout equipment. Programs have existed which utilized nearly identical equipment for both uses; other programs have existed in which any resemblance of the equipment was probably coincidental. Many factors have entered the final decisions, not the least of which were economic and schedule considerations, and, in some instances, the organizational structure of the developer."

  "The Challenge of Change vs the Control of the Process."

  The introduction states, "This paper is designed to present the Rocketdyne engine program as it applies to the Saturn launch vehicles and will apply to the Apollo program of manned flight to the moon (Fig. 1). The vehicle that will launch this flight is the Saturn V, the largest and most powerful of the Saturn family. This vehicle, 362 feet tall and 33 feet in diameter, will be capable of sending a 45-ton payload to the moon or placing a 120-ton payload in earth orbit. Five F-1 engines power the first stage of the Saturn V; five J-2 engines, the second stage; and one J-2 engine, the third stage. The thrust of the first-stage engines alone will be equivalent to 160 million horsepower. Both of these engines, the F-1 and the J-2, were designed at, and are currently being produced by Rocketdyne."

  "Chilldown Electrical System for S-IVB Space Vehicle."

  The paper is marked, "To be presented at the IEEE 1965 Aerospace Conference featuring Flight Vehicle Electrical/Electronics Systems, Houston, Texas, June 20-24, 1965." The abstract states "This paper presents the electrical system used to drive the chilldown motor pumps on the S-IVB space vehicle. This system consists of a 56 volt battery supplying power to the two three-phase solid state inverters which in turn drive two cryogenic motor pumps. Included in this paper is a short description of the overall chilldown system requirements. The advantages of the a-c system over the d-c system are discussed with emphasis on weight and reliability. Two functionally identical 1.5kva inverters were designed. One inverter uses germanium transistors in the output stage while the other uses silicon transistors. Both inverters were designed to have a quasi-square wave output. The inverter circuitry is described and the advantages of each is discussed including a comparison of weight, size, operating temperature, efficiency and voltage rating." Includes diagrams.
