Abstract: An arc-quenching composition that is suitable for deionizing and extinguishing a high-voltage electrical arc comprises an arc-extinguishing material, such as melamine, and a binder, the binder including a thermoplastic polymer polymerized from a carboxylic acid moiety-containing monomer either as a homopolymer or as a copolymer with another monomer, preferably ethylene acrylic acid.  The composition comprises effective amounts by weight of the arc-extinguishing material and the thermoplastic polymer to achieve the desired combination of arc-extinguishing properties and structural characteristics, such as tensile strength, elongation, and environmental resistance to thermal cycling.  Additionally, the composition for various applications and uses may include additives, fillers or fibrous materials.  The composition is achieved by compounding of the powdered constituents using dry blending, roll mill, extrusion and/or other plastic compounding techniques to obtain a molding resin.  The molding resin is then molded into articles of the desired shape using well-known plastic processing techniques, such as injection molding, extrusion, and the like.  In a preferred composition to form a trailer for an interrupter, an ethylene acrylic acid copolymer is combined with melamine to achieve the desired arc-extinguishing and structural characteristics by virtue of the bonding, reaction and/or miscibility between the melamine and the ethylene acrylic acid.

Title: Entropy encoder/decoder including a context extractor
IPC: H03M7/38
Filed: 1990-04-24
Abstract: ENTROPY ENCODER/DECODER             INCLUDING A CONTEXT EXTRACTOR          Abstract In entropy, e.g., arithmetic or adaptive Huffman, encoding/decoding a context based on prior symbols is needed to provide accurate predictions of symbols to be encoded/decoded. Encoding/decoding efficiency is improved by employing an adaptive context extractor. The adaptive context extractor automatically adjusts the configuration of the lag intervals used to define the context. This is realized by adaptively incorporating into the context configuration at least one lag interval found to have a "good" predictive value relative to the particular symbol stream being encoded/decoded. The context configuration adjustment is such that the at least one found lag interval is exchanged with the lag interval currently in an at least one so-called floating predictor position. (FIG. 1)
