A device for analyzing or inspecting a prepared portion of a power cable includes a cable gripping section to grip a portion of the power cable proximate to a prepared end of the power cable, where the cable end has been prepared by removing certain portions of the power cable so that it can properly accept an electrical or cable accessory, such as a splice or termination. The device also includes an imaging device holding section to hold an imaging device at a predetermined radial distance from the prepared cable end. In particular, the imaging device holding section is radially and axially adjustable in position. During inspection of the prepared cable end, the imaging device is fully rotated about the prepared cable end to acquire a 360 degree image of the prepared cable end.

A process for preparing polar disulfone-functionalized molecules, which process comprises performing one or more of the following reactions:

Method of preparing polar disulfone-functionalized molecules

This invention provides synthetic routes for novel single isomers of monocarbamate diols and their polymerization to provide novel polyesters, polyurethanes, polycarbonates, and the like having pendant carbamate groups on the polymer chain. Devices using some of these novel polymers which demonstrate nonlinear optical activity are also disclosed.

Preparation of monocarbamate diols

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.

Nonlinear optical materials containing polar disulfone-functionalized

The present invention provides fluorine-containing arylazoanaline dyes that are useful in thermal transfer systems. Specifically, the present invention provides thermal transfer donor sheets containing dyes of the following formula: ##STR1## wherein: R.sup.1 is a (C.sub.1-20)alkyl or hydroxy(C.sub.1-20)alkyl group; R.sup.2 is a hydroxy(C.sub.1-20)alkyl or (C.sub.1-20)alkylene--OC(O)NH--(C.sub.1-20)alkylene--OC(O)--R.sup.4 wherein R.sup.4 is a (C.sub.1-20)alkenyl group or a polymerized alkenyl group; and R.sup.3 is F or CF.sub.3. Useful dyes of this formulation are stable under ambient conditions for at least about 6 months.

Thermally transferable fluorine-containing AZO dyes

A second order nonlinear optically-active azo monomer comprising a benzimidazole moiety. The monomers can be incorporated into both linear and crosslinked polymers useful in electrooptical devices.

Benzimidazole-derivatized azo compounds and polymers derived therefrom
