Abstract:
An electrical connector includes an electrically insulative cylindrical housing, an electrically conductive member retained within the cylindrical housing, and at least one biasing member biased toward a surface of the conductive member. The conductive member defines a longitudinal axis and the biasing member(s) is/are circumferentially disposed about the longitudinal axis of the conductive member. Conductors inserted into the cylindrical housing are urged into electrical contact with the conductive member by the biasing member(s).
Abstract:
Fluorine-containing liquid crystal compounds comprise a fluorocarbon terminal portion having at least one catenary ether oxygen and a hydrocarbon terminal portion, the terminal portions being connected by a central core. The compounds have smectic or latent smectic mesophases.
Abstract:
Fluorine-containing, chiral liquid crystal compounds comprise (a) an aliphatic fluorocarbon terminal portion containing at least two catenary ether oxygen atoms; (b) a chiral, aliphatic hydrocarbon terminal portion; and (c) a central core connecting the terminal portions. The compounds have smectic mesophases or latent smectic mesophases and are useful, for example, in liquid crystal display devices.

Abstract:
Compounds are provided which comprise a fluorocarbon terminal portion and a chiral hydrocarbon terminal portion, said terminal portions being connected by a central core, said compounds having tilted smectic mesophases or having latent tilted smectic mesophases which develop when said compounds having said latent mesophases are in admixture with said compounds having tilted smectic mesophases or said compounds having latent tilted smectic mesophases.
Abstract:
A process for preparing polar disulfone-functionalized molecules, which process comprises performing one or more of the following reactions:(i) reacting a vinyl ether disulfone molecule with an activated aromatic molecule, an activated heterocyclic molecule, a dye base, or a dye olefin;(ii) reacting an enamine disulfone molecule with a dye base or a dye olefin; and(iii) reacting an alkenyl disulfone molecule having a vinylogous methyl or methylene group conjugatively located relative to the disulfone group with an aldehyde or an acetal derived from an aldehyde.
Abstract:
Nonlinear optical (NLO) compositions are disclosed which contain polar disulfone-functionalized molecules (PDFMs) incorporated in a polymeric material. When aligned noncentrosymmetrically in the polymeric material, the PDFMs generate a second-order NLO response. There is also disclosed: a method of preparing a NLO composition; novel PDFMs and novel polymers; and a new process for preparing PDFMs.

Abstract:
An electrical splice connector includes a housing, a conductive member retained within the housing and defining a longitudinal axis, and at least two biasing members circumferentially disposed about the longitudinal axis of the conductive member and biased toward the conductive member. Each of the biasing members is configured to urge conductors inserted into the housing into electrical contact with the conductive member.
