Abstract: Moisture curable flame retardant insulation compositions for wire and cable having improved adhesion are provided. The compositions are comprised of an ethylene-silane copolymer, high density polyethylene resin, halogenated flame retardant, silanol condensation catalyst and stabilizer combination consisting of a zinc mercaptobenzimidazole and aromatic secondary amine.

Abstract: Crosslinkable, flame retardant insulation compositions having improved resistance to scorch are provided. The compositions are comprised of a base resin, hydrated inorganic filler, coupling agent and stabilizer and formulated with a peroxide/scorch retardant combination, specifically, a combination of ?,??-bis(t-butylperoxy)diisopropyl benzene and 2,4-diphenyl-4-methyl-1-pentene.

Abstract: An insulating composition for electrical conductors that is composed essentially of an ethylene-vinyl acetate copolymer, a zinc salt, aluminum trihydrate, and a peroxide curing agent is surprisingly found to have excellent long-term thermal stability with fast cure.

Abstract: Flame retardant compositions useful as insulation for 150° C.-rated wire and cable applications are provided. The compositions of the invention utilize an ethylene-alkyl acrylate copolymer base resin with a two-component stabilizer package consisting of a zinc salt of a mercaptobenzimidazole and an aromatic secondary amine compound. Also, included to achieve the requisite flame retardance, crosslinkability and physical properties are a brominated flame retardant, antimony trioxide, a hydrated inorganic filler and a chemical crosslinking agent.

Abstract: A system for concurrent processing of queries and transactions against a shared database. The system includes multiple processors wherein a processor is available for processing queries and another processor is available for concurrently processing transactions. A query buffer is established for performing the query search while the data accessed by transactions is available in a database cache. Control logic in a database management system distinguishes between transactions and queries and initiates file-read control for reading the file containing the database. File-read control contains logic for logical sequential reading and logical non-sequential reading of the file. Control structures provide a means for control over the load that the query is allowed to place on the system.

Abstract: Novel poly(keto-esters) having carbonyl and oxycarbonyl units randomly combined with linking units derived from olefinic monomers to form an essentially straight-chain polymer backbone are provided. The poly(keto-esters) are produced by converting a portion of the carbonyl functionality of a polyketone to oxycarbonyl groups. The conversion is achieved by reacting the polyketone with an organic peroxyacid in an inert liquid medium at a temperature from -20.degree. C. to 150.degree. C.

Abstract: A facile process for converting polyketones to polyesters is provided. The process involves reacting a polyketone, such as an ethylene-carbon monoxide copolymer, with an organic peroxyacid oxidizing agent in an inert liquid medium at a temperature from -20.degree. C. to 150.degree. C. to convert substantially all or only a portion of the keto functionality to ester moieties.
