Abstract: A thermally expandable wax composition and its use in polymer-based actuators is disclosed and claimed. The compositions are wax-based and include conductive filler as well as a viscosity modifier to stabilize the composition against segregation. Optionally included are thermoxidative stabilizers.

Abstract: This invention discloses a thermally expandable composition for use in actuators. The composition contains about 10-50 volume percent hollow glass spheres in a wax or a polymer. The spheres contain a conducting coating affixed thereon. During use in an actuator, the composition is heated to melt the wax or polymer, when the density of the spheres substantially match the density of the melt, thereby substantially eliminating phase separation. The high thermal conductivity of the composition increases the speed of heat transfer out of the composition during the cooling cycles.

Abstract: Blends of thermotropic liquid crystalline polymers and isotropic melt-processable polymers are made by extruding a molten stream of either a thermotropic liquid crystalline polymer or an isotropic polymer through a heated mixing zone and feeding the other of the two polymers into the stream of the first polymer in the mixing zone. The polymers are mixed under shearing conditions for a time sufficient to yield a uniform blend. Blends made according to this method exhibit improved properties in comparison with blends obtained by feeding the two polymers simultaneously into a heated mixing zone.

Abstract: A low dielectric material made of a liquid crystal polymer, polytetrafluoroethylene, and hollow glass spheres. This material is a relatively low cost, low dielectric blend having good physical strength and chemical and temperature resistance.

Abstract: A system incorporating a pair of Mach-Zehnder modulators (164,166) for performing amplitude modulation of an optical carrier is disclosed. Each of the modulators is designed to suppress even order distortion products and develop third order distortion products of opposite sign and equal magnitude. The outputs of the two modulators are combined in a directional coupler (155) resulting in substantially suppressing second through fourth order distortion products.

Abstract: A method is disclosed which uses the Langmuir-Blodgett method to coat a substrate with multiple monomolecular single layers by immersing the substrate through a first layer of a first enclosure of a tank having first and second enclosures on a common subphase, and then withdrawing the substrate through a second layer in the second enclosure. The steps are repeatable to provide as many different single layers as required.
