"2 Sept 1968 -Kerry, IMK & Lucky at 5130 Panorama, Backyard & frontyard."
Film shows Kerry crawling and walking in the Dannenbergs' yard alongside Ingeborg and Lucky. Monte Sano, Huntsville, Alabama. Konrad Dannenberg's note on the film box reads, "2 Sept 1968 - (Klaus and Betty are in Acapulco, (Mex) / Kerry, IMK & Lucky at home - Ks first steps / first in Backyard then - frontyard / K winds up crying!" Fall 1968. -
"25 Aug 1968 - Kerry in Backyard climbing stairs."
Video shows Kerry Dannenberg crawling around the Dannenbergs' backyard, with appearances by Lucky, Klaus, and Betty Dannenberg. Konrad Dannenberg's note on the front of the film box reads, "First attempts to walk / but he keeps on crawling." On the reverse, his note reads: "25 Aug 1968 - Kerry in Backyard / 5130 Panorama / also w/Lucky crawling on lawn / crawling up/down steps." Summer 1968. -
"2nd Xmas film 1963."
Konrad, Klaus, and Ingeborg Dannenberg open presents with company over during Christmas at the Dannenbergs' house in Monte Sano, Huntsville, Alabama. Konrad Dannenberg's notes on the film box read, "Unwrap gifts [illegible] ... Ulla, George, Erna, Alma, Kl, IMK + Ko Under X mas tree." Winter 1963. -
"A 'Zero Stage' for the Saturn IB Launch Vehicle."
To meet the demands of increasing payload size and weight, and to fill the large payload gap between the Saturn IB and Saturn V, a number of methods of uprating the Saturn IB have been studied by NASA and Chrysler Corp. of providing increased payload capability is discussed in this paper. Four 120 in. United Technology Center UA-1205 solid propellant motors, originally developed for the Air Force Titan III program, are clustered around the S-IB first stage of the Saturn IB launch vehicle. These four solid propellant motors provide the total thrust for liftoff of the vehicle, with S-IB stage ignition occurring just prior to burn-out and separation of the solid propellant motors. The term "Zero Stage" is applied to this added stage. -

"A Comparison of Advanced Cooling Techniques for Rocket Thrust Chambers".
The document is a technical paper for Astronautics and Aerospace Engineering Magazine.The copy has handwritten notes that appear to be for revisions. The abstract states "In the early days of rocket propulsion, two primary methods were employed for cooling the walls of thrust chambers. These were uncooled metal chambers where the heat sink capacity of the chamber and nozzle wall materials limited the operating duration, and regeneratively cooled chambers where one of the propellants was circulated in a cooling jacket which constituted the chamber wall. Today, there are at least fourteen different methods with variations for cooling the combustion devices and nozzles of liquid propellant, solid propellant, and/or nuclear rocket propulsion engines. It is the intent of this paper to examine these methods, to describe for each the useful range of operating conditions, as well as present and likely future applications, to define their limitations and associated problems. Emphasis is primarily placed on liquid rocket engines." -
"A Comparison of an MIT Explicit Guidance Principle with MSFC Iterative Guidance."
From the summary: "Both [guidance] schemes steer toward a specified end point. The MIT scheme uses thrust to cancel out the effective gravity, a nonlinear term, which may be inefficient in certain cases. The MSFC scheme is more closely connected with calculus of variations and optimization theory in a reasonable degree of approximation." -
"A comparison of four control systems proposed for Saturn V launch vehicles."
Presented are the results of a study comparing four proposed control systems for the first stage flight of Saturn V launch vehicles. The primary basis of comparison is the effect on structural loads, using the bending moments at three stations as load indicators. Two of the systems sense only the vehicle attitude and attitude rate, while the other two systems also sense the lateral acceleration. A yaw plane wind response analysis, including rigid body translation, rigid body rotation, four bending modes, five slosh modes, and a non ideal control system, was performed. The winds used in the study were the Marshall synthetic profile and three selected Jimsphere-measured real wind profiles. Load relief obtained from the addition of accelerometer feedback in the control loop amounted to about 10 percent at maximum bending moment station. In view of predicted structural capabilities of the vehicle, this reduction in loads was not considered sufficient to offset the added complexity and the slight reduction in rigid body stability .
