"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, -

"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. -
