German analysis of preparatory technology of U.S. space programs, noting effects of hardware development for manned space travel on future planning
Design philosophy for cost reductions on future space transportation systems, exemplifying application to booster system for earth orbital logistics

Semi-rigid coaxial cable forms the helical element of antennas. Antennas are inexpensive, corrosion resistant, require minimum maintenance, and can be easily transported and assembled.
Gas chromatograph sampling system consists of a manifold with a gas-sample valve, a minimum-volume pressure transducer with a portable monitor, a vacuum-source valve, and a sample inlet valve. Increased accuracy of analysis is obtained by better control of sample size.
Capillary tube flowmeter measures ultra-low flows of very corrosive fluids /such as chlorine trifluoride and liquid fluorine/ and other liquids with reasonable accuracy. Flowmeter utilizes differential pressure transducer and operates on the principle that for laminar flow in the tube, pressure drop is proportional to flow rate.
Techniques for preparing printed circuit boards are used to provide an alternate method for producing panel symbology for ground computer test trap. After processing, the panel unit is either solder or gold plated.
Computer program for analyzing New Hampshire highway traffic flow by using models
Antenna system handles data acquisition and tracking, functions as a sensitive radio telescope, and serves as a radiometer in earth atmosphere investigations. Antenna's sensitivity permits resolution of solar disk quadrants in Doppler radar observations. Antenna also serves as a planetary radar device and link to commercial aircraft.
Cost analysis of turbofan nacelle modifications to minimize fan-compressor noise radiation
Evaluating cost of four processes for production of oxygen difluoride - fluorine-caustic least expensive
Cost estimates and feasibility of compression molded plastic motor cases and nozzles for solid rockets
Effects of space shuttle on costs, mission objectives, and operational modes of OAO/LST program
Liquid nitrogen cold trap for oil diffusion pump
Seasonal and year-to-year crop radar sensing in agriculture for socioeconomic applications
Manned orbital operations economy for space station utilization, discussing laboratory equipment, on-orbit supervision, maintenance and remote communications limitations
Inexpensive formed-plastic vent cover has been developed that allows controlled purge of vent systems and also provides blowout protection. Cover can also be used in relief mode to allow normal system relief flows without disengaging from vent system. Cover consists of two parts made of plastics with varying densities to fit media used and desired pressures.
Recent studies conducted in the Bonanza Test Site, Colorado, area indicated that: (1) more geologic structural information is available from remote sensing data than from conventional techniques; (2) greater accuracy results from using remote sensing data; (3) all major structural features were detected; (4) of all structural interpretations, about 75% were correct; and (5) interpretation of remote sensing data will not supplant field work, but it enables field work to be done much more efficiently.
