Abstract: A telescopic retractable mast system for deploying a solar panel array comprising a one or more of masts, each mast comprising sections, means for retracting and extending each mast and means for mounting and deploying a plurality of solar panel thereon such that the solar panels are and may be adjustable as to maximize the electrical output therefrom. When in use, the mast system may be extended upwards to allow solar generation to take place and when conditions are not appropriate, such as inclement weather, the mast and therefore the solar panels may be retracted into a protected configuration, such as into an enclosure.

Abstract: Implements, particularly medical instruments, formed at least in part of elongated polymer members, exhibit high torque fidelity after processing with tension, heat, and twisting. The processing orients the polymer in generally helical paths so that torque imposed at the proximal end can be transmitted to the distal end without substantial whipping, even if the implement follows a long and tortuous pathway. Applications include medical guidewires, catheters, and driveshafts.

Abstract: A catalytic hydrogenation process for preparing alkyl-1,3-diaminopropanes by contacting an alkyl aminopropionitrile in the liquid phase with hydrogen and ammonia in the presence of a non-reactive organic solvent and a hydrogenation catalyst, the process conducted at a rising reaction temperature (.DELTA.T) along with the progressive vaporization of the solvent.

Abstract: An autopilot automatically adjusts the sensitivity of a ship's steering system to accommodate changes in speed as well as sea and wind conditions. The autopilot utilizes heading error, speed and speed squared signals to produce a rudder order signal for controlling rudder position. The rudder order signal is developed in a heading keeping circuit unless a heading change greater than a predetermined threshold is commanded, in which event a programmer substitutes a heading change circuit for the heading keeping circuit. The sensitivity of the heading change circuit is automatically adjusted as an inverse function of vessel speed squared, and automatic rudder order limits are established in the same circuit as an inverse function of speed. The sensitivity of the heading keeping circuit is adjusted in accordance with a signal from an automatic gain control circuit which derives a performance index J from ship's speed, heading error and rudder order signals occurring during a given measurement interval.

Abstract: A method of preparing acylisoxazolines by contacting an alkene with dinitrogen tetroxide and oxygen in the presence of a denitrating agent and calcium oxide.

Abstract: An alkylene oxide adduct of phosphosulfurized N-(hydroxyalkyl) alkenylsuccinimide characterized by the formula: ##STR1## where R.sup.1 is alkenyl of from 10 to 30 carbons and X and Y are divalent saturated aliphatic hydrocarbon radicals of from 2 to 6 carbons. In addition, automatic transmission fluid compositions and concentrates thereof comprising a major amount of a lubricating oil and a friction modifying amount of the alkylene oxide adduct and method of operating an automatic transmission having friction sensitive power transmitting means employing the aforedescribed automatic transmission fluid composition.
