Abstract: A liquid crystal display is made from an encapsulated liquid crystal structure comprising a liquid crystal composition dispersed in a containment medium. Selected additives may be added to the encapsulated liquid crystal structure to improve performance characteristics such as the operating field, the hysteresis, and the voltage holding ratio.

Abstract: A liquid crystal projection display, having (a) a light source for producing light of at least two different primary colors; (b) an imaging element corresponding to each primary color light produced by the light source, each imaging element comprising plural pixel elements, each pixel element comprising liquid crystal composition dispersed in plural volumes in a containment medium and being independently addressable to primarily scatter light incident thereon in the absence of a sufficient electric field and to primarily transmit light incident thereon in the presence of a sufficient electric field; and (c) a lens for projecting light transmitted by each imaging element onto a screen; the liquid crystal composition in the pixel elements of the imaging element corresponding to the primary color light of longest wavelength including a pleochroic dye of a color complementary to the primary color light of longest wavelength, which pleochroic dye preferentially absorbs incident light which has not been scattered b

Abstract: An electrical apparatus having a liquid crystal fault indicator, comprising: an electrical component subject to electrical fault; a smectic liquid crystal display having an indicating element having a first and a second visual state, said indicating element being capable of transitioning from the first to the second visual state upon the application of an electric field sufficient to realign the smectic liquid crystal material contained therein and remaining in the second visual state after the removal of the electric field and further being capable of transitioning from the second to the first visual state upon heating to at least a delatching temperature Td sufficient to destroy the electric field induced alignment of the smectic liquid crystals; and fault signal means for providing, upon the occurrence of a fault, a prescribed input sufficient to cause said indicating element to transition from a visual state indicative of an unfaulted condition to a visual state indicative of a faulted condition.

Abstract: A method of stabilizing a poly(arylene ether ketone), which method comprises in one embodiment heating the poly(arylene ether ketone) at a temperature between about 240.degree. C. and about 325.degree. C. for a period of between about 0.5 and about 24 hours, prior to any melt-processing of the poly(arylene ether ketone) and in another embodiment hydrothermally treating the poly(arylene ether ketone) by heating it to a temperature of at least 160.degree. C. while contacting it with water.
