Abstract: Water-soluble polymers are formed by combining a water-soluble analog of a water-insoluble monomer, such as a water-insoluble redox monomer, with a water-based solvent and an enzyme. The water-soluble polymers formed can be electrically conductive or optically active. The water-soluble analog can be copolymerized with a water-insoluble redox monomer to form a copolymer that is also water-soluble. Polymers formed by the method of this invention can be layered on a surface to form, for example, alternating layers of polyanions and polycations.

Abstract: A novel photocrosslinkable polymeric system has been developed for processing into films having stable second-order nonlinear optical properties. In the present system, polymers bearing photo-crosslinkable chromophores, such as polyvinylcinnamate and are reacted with appropriately designed nonlinear optical molecules with the cinnamate or other photocrosslinkable functionalities for photocrosslinking at one, two or more points. The system can be poled and photocrosslinked in the poled state to yield a material with stable optical nonlinearity and large electro-optic coefficients.

Abstract: A self-deploying structural element formed of a core or temperature sensitive expanding foam, a load carrying component of advanced composite material, and an outer retaining jacket. A heat generating means such as resistance heating wires is included to initiate deployment of the structure. The heating of the structure causes the foam core to expand, unrolling or unfolding the structure. The heat also cures the advanced composite material to a rigid form. The retaining jacket is preferably a heat shrink jacket which contracts around the composite material.

Abstract: A family of ionic polyacetylenes containing long sequences of conjugated double bonds in the backbone with ionic charges adjacent to or in conjugation with the backbone, and a synthetic process for preparing them, are disclosed. These polymers, which are soluble in many solvents including water, are mono- and di-substituted polyacetylenes that are extensively conjugated. The charge density and geometry of charge distribution depends on the number and nature of the substituents.

Abstract: A compliant device holding the work-piece part in an assembly, grinding, sanding or polishing process has a rotational compliance which matches the rotational compliance of a compliant device holding the work tool part or part to be assembled with the receiving part. A contact force between the two parts thus causes each part to rotate the same amount about any axis perpendicular to the direction of relative motion between the two compliant devices, thereby preserving the relative orientation of the two parts.

Abstract: An apparatus and method is described for inserting pins in holes wherein either the pin or the hole is chamfered or beveled. One part is vibrated with respect to the other in a plane orthogonal to the direction of insertion. One part is incrementarlly moved in the direction of insertion. When interference caused by the contact is sensed, the magnitude of the interference is determined and used to reposition the center-line of the one part in the orthogonal plane until the pin is fully inserted.
