Abstract: An improved framed structure incorporating a coupled-girder system provides enhanced seismic energy dissipation by as much as 30% over that provided by conventional yielding of the girders. The coupled-girder system includes a pair of spaced-apart girders coupled by one or more girder-to-girder links which are preferably vertical links. Energy dissipation takes place when the structure drifts beyond its elastic limit and the differential displacement of the pair of girders causes the web of each vertical link to shear yield. The links are proportioned to remain in the elastic regime under wind loads and moderate earthquakes as prescribed by building codes. Beyond the elastic limit, preferably the yielding in the links will take place prior to that in the girders. In this way, the links will be the first line of defense for dissipating seismic energy before the girders themselves.

Abstract: While the manufacturing of integrated circuits (IC) has become a mostly automated process, the loading of the ICs into storage and shipping tubes 105 still requires a large amount of human interaction. A major stumbling block to the automation is the removal and insertion of retention pins 115 in the tubes.

Abstract: A seed harvester pod and method are provided for harvesting seeds from the cones of a live, free-standing, coniferous tree. The pod comprises an open-sided conical frame, open at the top and bottom, supporting a permeable side wall, which may be netting. The netting is operative to allow penetration of sunlight, air and rain. However it will prevent the passage therethrough of airborne seeds released by the cones of the tree.

The pod can be lowered by a helicopter line onto the conical upper end of the tree, prior to cone maturation. After the cones have opened and the seeds have matured, released and become airborne, they are contained by the netting, drop and collect in the trough. The harvester is then later retrieved from the tree and the seeds are recovered.
