Synthesis of spherical minimum-weight proton shields
A systematic method has been developed for minimizing spherical shield weights for protection against proton radiation, including secondary neutron production, subject to various specified dose constraints. Variational methods are applied to a radiation model yielding the choice of optimum shielding materials and their mixtures, together with a prescription for their disposition in a multilayer spherical shield.

Microlock- a minimum weight radio instrumentation system for a satellite
The design, construction and laboratory testing of a satellite tracking system are described. The tracking mechanism employs a low power, lightweight flight transmitter in conjunction with a receiving system of advanced design. The flight transmitter will radiate 3 mw for three months and will provide two narrow hand telemetering channels in a unit having a total weight of 2 lb. The ground receiving equipment is capable of acquiring and tracking the beacon signal at a line-of-sight distance of 3000 miles and at any azimuth and elevation angle. Interferometer antennas could he used to determine the angular position of the satellite with an accuracy of one milliradian, which is equivalent to approximately ±0.04 sec in the determination of the period.
