"Signal distribution in automatic checkout systems."
This paper deals with several selected aspects of the signal distribution in automatic checkout systems. These are: 1) The use of relay matrices as control elements; 2) The inclusion of self-checking capabilities; 3) Problems of systems integration. These aspects are not unique to automatic checkout systems. However, due to the nature of automatic checkout systems as presently being designed around digital circuitry, they find either fuller or different applications than in other types of systems. Also, while they are on the surface somewhat disconnected in nature, they tend to interrelate during the implementation of an automatic checkout system. -
"The significance of parameters affecting the heat transfer to the liquid hydrogen in the Saturn S-IVB stage for the lunar orbit rendezvous mission."
The Saturn S-IVB stage has a requirement for orbiting around the earth for up to 4.5 hours with approximately 60 percent of its initial propellant remaining at the end of the coast (prior to restart) . Extensive analyses must be performed to insure that this requirement is met. Both the maximum and minimum heat transfer rates are important because the maximum rates affect the hydrogen boiloff losses and thus the initial propellant loading requirements. The minimum rates are important because the boil off gases are used to maintain a minimum axial thrust level by venting the gases continuously through aft facing nozzles. This provides for a settling of the propellant throughout the orbital coast and alleviates the need for periodically venting the tank under zero gravity. -

"Saturn V vehicle electronics."
This presentation is a review of the electrical and electronics systems of the Saturn V launch vehicle. Since airborne and ground electronics cannot be separated as a system, this presentation will touch upon both the airborne and ground checkout equipment. Certain airborne electronic items are singled out in order to elaborate upon the application of computers for checkout and launch. This review covered in a broad sense such airborne electronics as the control computer, the measuring telemetry and RF systems, the switch selector, the digital command receiver and the remote automatic calibration system. The ground support equipment electronics covered include such equipment as the data link, computer system and display systems. The importance of software in the Saturn V program is stressed by the application of a standard program language through the use of acceptance test or launch language (ATOLL). -
