    Abstract: Electrically conductive carbon flakes and films are prepared in high yield by the pyrolysis of cyclic aromatic hydrocarbons, optionally halogenated, in the presence of a dehydrogenating agent at about at least 800.degree. C. Flakes of thicknesses up to 20 .mu.m and lengths up to 1 cm on a side are metal-like in appearance and have a conductivity of about 200-300 S/cm at room temperature. By heat treatment to 2600.degree. C., graphitic order is improved and the conductivity rises to .apprxeq.10000-15000 S/cm.

    Abstract: A liquid crystal composition for improved electro-optic displays. The composition undergoes an electrically induced cholesteric-nematic phase transition and includes fluorescent materials which are excited by ultra-violet radiation. In the cholesteric phase of the composition, the fluorescence is much stronger producing sufficient contrast to render the display visible in the dark.

    Abstract: A container for a liquid crystal cumulative dosimeter including a resilient outer body sealed to confine a first liquid crystal composition constituent and a second liquid crystal composition constituent and having at least one transparent section to permit observation of the color of the confined composition, and a barrier contained completely within and physically unattached to the outer body for separating the first constituent from the second constituent, whereby disruption of the barrier allows the first constituent to mix with the second constituent. The barrier is formed either by encapsulating one or both of the constituents or by using air bubbles. Methods of manufacturing the various containers shown and processes of using those containers are also disclosed.

    Abstract: An electrolytic cell wherein one of the elements is comprised of a canal clathrate complex of benzophenone and a polyiodide salt of a cation from a group consisting of potassium (K.sup.+), sodium (Na.sup.+), cesium (Cs.sup.+), lithium (Li.sup.+), ammonium (NH.sub.4.sup.+), rubidium (Rb.sup.+) and tetraalkylammonium (R.sub.4 N.sup.+ where R is an alkyl group of less than five carbons). This complex functions through its tunnel-like dispositions of the cations, having certain unfilled sites and certain other sites occupied by the CHCl.sub.3 molecule, as a solid fast ion conductor. The same composition, again apparently because of the canal clathrate complex crystal structure, is adapted, by virtue of its electronic conductivity to function as an electrode in an electrolytic cell.

    Abstract: Cumulative temperature dosimeter utilizes a temperature dependent reaction in a cholesteric liquid crystal composition to produce a color change indicative of temperature exposure over a period of time.Typically, the composition includes, as a solvent, a cholesteric liquid crystal, such as a mixture of p-methoxy-p'-n-butyl-azoxybenzene, cholesteryl nonanoate, cholestyl chloride, and cholesteryl oleyl carbonate. One or more solutes are included, the solutes being reactive at a rate which is temperature dependent, to cause either generation or consumption of mesogenic compounds. In turn, the pitch of the solvent, observable as a visible color change, is affected in proportion to the cumulative temperature exposure of the composition.

    Abstract: A tamper evident over-wrap is disclosed which employs a multi-layered system including three overlapping layers of containment material and two interleaved layers of reactive material, at least one of which is a gel. Upon formation of an opening of the middle layer of containment material, the previously-isolated layers of reactive material will intermingle and react. These materials react to form a color change. By using a gel, manifestations of tampering attempts are considerably enhanced.
