Scholars typically will present histories as chronological events of specific occurrences or happenings. Topics have or will be written and presented which perhaps are supported by the industries formal documented files covering chronological progression of actual devices and covering functional changes of these devices. Research of related material to present these specifics will be left to my colleagues in the Agricultural Industry. Conscious of this effort and the requirement to extend rather than to repeat what has been or is anticipated to be presented, this history will cover another significant but equally as interesting a topic more befitting to our current interests. The topic is “Reliability History of Electronics in Agriculture”.

This report presents the results of a study performed in order to analyze and develop the most effective means of supporting the NAVSTAR Global Positioning System satellite (GPS) program interfaces with the Space Transportation System (STS). The approach to this study was to look at the various methods in planning, organizing, manning, and implementing the GPS STS operations support team. The major emphasis in this report is the background of the GPS program, STS commercial and DOD STS operations, and the organizational options that were available from which a decision was made and is being implemented. Our conclusion was that a modification to the existing DOD mission operations concept will not only maintain the integrity and maximize the effectiveness of the GPS operations control team but will also minimize the manning and maximize the use of the NASA standard services to STS customers.

PORSCHE is developing a new family of airplane engines for the power range from 200 to 300 hp. Development of the first engine was completed in 1984, and certification to JAR-E and FAR Part 33 is complete. This horizontally-opposed 6-cylinder powerplant with propeller drive has a take-off power of 212 hp with full exhaust muffling. It is fitted with an automatic fuel injection system which works precisely at all altitudes, and is supplied by two electric fuel pumps. The two ignition systems are electronically controlled. Current supply to the engine and to the aircraft is ensured by two independent alternators. The engine is cooled by an engine-driven fan which functions proportionally to power output. The pilot controls engine power, engine speed and mixture to continually optimized values by means of a single lever. The engine can be operated on both AVGAS and MOGAS.

A new principle has been employed in an adaptive control for spot welding of unknown types of steel. The dynamics of the process is monitored, not materials properties or energy input etc. The rate of rise of the temperature, as reflected in the rate of rise of the resistance, provides all the necessary information. The control algorithm and a series of evaluative tests are described. Any conventional welding machine equipped with the new control will make sound welds the very first time, in HS or LC steel of two or multiple thicknesses, with electrode diameters as different as 2:1, and in the presence of shunting. A “teaching mode” is not required.
