Payload installation and deployment aid for Space Shuttle Orbiter spacecraft remote manipulator system
An aid concept known as the PIDA (Payload Installation and Deployment Aid) is presented as a way to assist the RMS (Remote Manipulator System) by relaxing the accuracy required during payload handling in the payload bay. The aid concept was designed and developed to move payloads through a prescribed path between the confined quarters of the payload bay and a position outside the critical maneuvering area of the Orbiter. A description of the design requirements and the modes of operation of the various functions of the deployment and the docking mechanisms are covered

Payload installation and deployment aid for space shuttle orbiter spacecraft remote manipulator system
An aid concept known as the PIDA (Payload Installation and Deployment Aid) is presented as a way to assist the Remote Manipulator System (RMS) by relaxing the accuracy required during payload handling in the payload bay. The aid concept was designed and developed to move payloads through a prescribed path between the confined quarters of the payload bay and a position outside the critical maneuvering area of the Orbiter. An androgynous docking mechanism is used at the payload/PIDA interfaces for normal docking functions that also serves as the structural connection between the payload and the Orbiter, that is capable of being loosened to prevent transfer of loads between a stowed payload and the PIDA structure. A gearmotor driven drum/cable system is used in the docking mechanism in a unique manner to center the attenuator assembly, align the ring and guide assembly (docking interface) in roll, pitch, and yaw, and rigidize the mechanism at a nominal position. A description of the design requirements and the modes of operation of the various functions of the deployment and the docking mechanisms are covered

\u3ci\u3eWilliamsonia Lintneri\u3c/i\u3e (Odonata: Corduliidae) - A First Michigan Record With Additional Notes on \u3ci\u3eW. Fletcheri\u3c/i\u3e
Williamsonia lintneri is newly recorded for Michigan, and additional Michigan sites are given for W. fletcheri. Both species appear to be bog/fen- obligate inhabitants, and adults may appear as early as late April in Michi- gan. In addition, the North American distributions of both species are sum- marized
AN EMPIRICAL ANALYSIS OF THE INTERTEMPORAL STABILITY OF RISK PREFERENCE
The interval measurement approach was used to obtain risk preference measures for 23 Michigan farmers in 1979 and again in 1981. This paper analyzes how risk preferences of the individuals in this group of decision-makers changed over a two year time period. Risk preferences were most stable near typically experienced personal income levels.Risk and Uncertainty,
Preparation of heterocyclic block copolymer from perfluoroalkylene oxide alpha, omega-diamidoximes
Diamidoxime monomers are intermolecularly and thermally condensed to form a heat and chemical resistant polymer containing 1,2,4-oxadiazole linkages with identical bivalent organic radicals or any combination of bivalent organic radicals selected from the group consisting of -(CX(sub 2))p-, wherein P ranges from 2 to 8 when X is fluorine and 2 to 18 when X is hydrogen, chlorine, nitro or aryl; arylene; and an oligometric or polymeric radical prepared by reacting a dicarboxylic acid halide with a fluorinated epoxide and having the formula: (CFY(OCF(sub 2)CFY)sub m)O(CX(sub 2))(sub p)O(CFYCF(sub 2)O)(sub n)CFY wherein Y is flourine or tryifluoromethyl, X is nitro, aryl, hydrogen, chlorine or fluorine, preferably the latter, p ranges from 1 to 18 and m+n ranges from 2 to 7
