Abstract: Improved uniformly expanded pyrolytic graphite, useful particularly as insulation material, e.g. heat insulator or heat shield, by a process comprising treating pyrolytic graphite with an intercalating agent, preferably a mixture of nitric and sulfuric acids, to cause the pyrolytic graphite to expand in a controlled manner only in the direction normal to the deposition surface (the c-direction) and continuing such treatment for a period sufficient to substantially completely delaminate the expanded pyrolytic graphite, and heating such delaminated expanded pyrolytic graphite under conditions constraining movement in the direction parallel to the deposition surface (the a-b direction) and permitting movement in the c-direction, to cause the delaminated expanded pyrolytic graphite to expand further to a controlled extent in the c-direction, forming an integral bonded expanded pyrolytic graphite expanded, e.g. from about 1 to about 10 times or more its original dimension in the c-direction.

Abstract: A filter spectrograph unit for use in a micro-Raman spectrometer system or a remote sensing system is formed by combining an infinitely variable spectral line rejection filter (having appropriate entrance optics) functionally and operatively with a dispersing spectrograph. The line rejection filter is a modified form of a zero-dispersion double monochromator having an input light signal including laser light scattered from, for examle, minute Raman-active particles. The modified double monochromator includes an acylindrical mirror positioned so that the laser line will exit through an aperture in the mirror and all other spectral lines will be reflected and reformed by the modified double monochromator into an output light signal containing all of the original spectral information, less the rejected laser line. The dispersing spectrograph is integrally coupled to the modified double monochromator and produces from the output light signal a display of the entire Raman spectrum suitable for parallel readout and rapid data analysis.

Abstract: Production of a separator, preferably in the form of a compartment, for insertion therein of a battery electrode, preferably by dip-coating a flexible porous substrate, e.g., potassium titanate paper or nylon, in a mixture preferably of a major portion of an inorganic or ceramic separator material, a minor portion of potassium titanate in short fiber form, and a minor portion of an organic polymer, e.g., polyphenylene oxide, dissolved in a suitable solvent such as chloroform. The flexible porous substrate is placed in the mixture, preferably maintained under vibration, and stirred; the substrate and applied coating are removed from the mixture, and the coating is dried to remove solvent and is cured at elevated temperature. The resulting porous separator, coated, filled or impregnated with the above mixture, has low resistivity, is smooth and uniform in thickness, and is flexible, and has high resistance to alkali and to elevated temperatures. Preferably the flexible porous substrate is first formed into a box or bag and then treated with the above mixture to form a separator. An electrode, such as a zinc electrode, is inserted in the bag either before or after coating and impregnation. Alternatively, a film or sheet of the substrate is treated with the above mixture to form a flexible separator, and the resulting flexible separator is then formed into a boxlike configuration for receiving an electrode, or is wrapped around an electrode or electrodes.
