Abstract: Antenna assemblies and stowage and restraint system thereof, comprising at least one dual band reflector having overall L-band-reflective properties and having a central stiffened Ku-band-reflective area having high reflector surface accuracy surrounded by a flexible annular area having L-band reflective properties. The reflector also has a support hingedly attached to a spacecraft body for deployment between a stowage position in which it is pivoted and restrained up against a face of the spacecraft body and the flexible annular reflector areas partially flexed therearound, and a deployed position in which it is enabled to relax and return to extended, parabolic condition.

Abstract: A system of substantially whole tree utilization wherein the trees are felled and subsequently slashed with the branches and top section intact to form discrete tree sections including a top section and branched bole sections, and these sections are fed into a conventional drum debarker to preferably dry and de-bark and de-branch the sections, thereby to provide branched and de-barked wood for further processing and separating bark, branches and needles. The bark and branches may be separated from each other and from the needles. The needles may be processed separately to produce chemical compounds for pharmaceutical purposes or any other use. The system of the present invention permits more economic harvesting of wood an increases the utilization of the tree by permitting utilization of not only the bole section, but also the normally unmerchandizable top and branches together with the needles.
