  • Patent number: 7533710
    Abstract: Apparatus for applying tax stamps to individual cigarette packages of different cigarette cartons, having different height dimensions, comprises a cigarette carton height determination station, a cigarette carton opening station, a cigarette package tax stamp application station, a cigarette carton closing station, and a cigarette carton exit station. Each particular cigarette carton has its height dimension determined at the first cigarette carton height determination station, and the height dimension data is transmitted to a programmable logic controller (PLC). The programmable logic controller (PLC) automatically adjusts mechanisms located at the various stations in accordance with the height dimension data characteristic of each cigarette carton.

  • Publication number: 20040084130
    Abstract: Apparatus and method for applying tax stamps to individual cigarette packages of different cigarette cartons, manufactured by different cigarette manufacturers and therefore having different height dimensions, comprises a cigarette carton height determination station, a cigarette carton opening station, a cigarette package tax stamp application station, a cigarette carton closing station, and a cigarette carton exit station. Each particular cigarette carton has its height dimension determined at the first cigarette carton height determination station, and such height dimension data is transmitted to a programmable logic controller (PLC). Cigarette carton opening mechanisms are located at the cigarette carton opening station, a tax stamp applicator is located at the tax stamp application stamper, and cigarette carton closing mechanisms are located at the cigarette carton closing station.

  • Patent number: 6063358
    Abstract: A process for producing alumina and other aluminia products where the formation of a Schiff base imine by reaction of a orgaonaluminum amide or imide oligomer with a carbonyl compound is promoted by the Lewis acid character of the oligomer. The water byproduct of the Schiff base serves as an in situ reagent for subsequent hydrolysis and sol-gel condensation of the aluminum species with concomitant production of alkane. The imine then is washed from the alumina with a suitable solvent. Any of a number of primary amines and aldehydes or ketones may be reagents. Calcining of the sol-gels yields high surface area alumina as characterized by scanning electron microscopy, and gas physisorption measurements. Microporous and/or mesoporous alumina is obtained depending on synthesis conditions. Alumina microspheres are obtained under certain conditions.

  • Patent number: 5204295
    Abstract: The disclosure is directed to compositions and methods for forming boron nitride coatings, using polymers derived from tri-substituted borazine and chloroborazine compounds. The polymeric compounds are mixed with ammonia, pyrolized at high temperatures to obtain a high temperature melt, and further converted to boron nitride coatings on various substrates. The polymeric compounds can be stored prior to pyrolysis.
