    摘要： The disclosed adhesive system comprises a curable liquid epoxide and a bisamino piperazine-containing thermoplastic polyamide hardener or co-curative. This adhesive system forms high strength metal-to-metal bonds with unusually high T-peel strength, high tensile shear strength, excellent low temperature properties, and good impact resistance while possessing the fast assembly speed characteristics of a hot melt. Both two-part and stable one-part curable systems can be formulated from (a) suitable epoxy resins and (b) the bisamino piperazine-containing thermoplastic polyamide.The particularly preferred polyamide comprises the amidification product, at temperatures of from 180.degree. C. to 300.degree. C., of:(a) from about 25-35% by weight of a diamine component comprising:(1) from about 45-65 equivalent percent of 1,4-Bis(3-aminopropyl) piperazine;(2) from about 15-35 equivalent percent polyoxypropylene diamine containing about 2 to about 35 repeating oxypropylene units;(3) from about 15-35 equivalent percent piperazine;(b) from about 65-75% by weight of a dicarboxylic acid component comprising:(1) from about 70-100 equivalent percent polymerized tall oil fatty acid having a dimeric fatty acid content greater than 90% by weight;(2) from about 0-30 equivalent percent azelaic acid.

    摘要： A mobile road or like surface sweeping machine has a gutter brush and a brush driving hydraulic motor carried on a supporting structure which is mounted on the machine frame for compound vertical and horizontal swinging movements from a stowed position, with the brush in close to the machine frame and elevated and out of contact with the ground surface, to an extended operating position relatively wide of the frame and in pressure engagement with the surface to be swept. The brush rotates about a generally vertical although slightly tilted axis. A single power operated means, a hydraulic ram, operates the supporting structure to produce the compound vertical and horizontal swinging of the latter. When the brush encounters increased resistance to rotation, for example due to built-up or heavy debris, the pressure of the hydraulic fluid at the motor inlet increases, and the ram responds to that condition by forcing the brush into greater pressure contact with the surface, thereby ensuring greater capability of sweeping the obstruction.

    摘要： NOVEL COMPOSITIONS ARE PREPARED BY THE REACTION OF A POLYAMIDE OR POLYAMINE WITH AN N-3-OXOHYDROCARBONSUBSTITUTED 3-ALKOXY-, 3-MERCAPTO- OR 3-AMINOPROPIONAMIDE OR SIMILAR COMPOUND. THESE COMPOSITIONS ARE USEFUL AS CURING AGENTS FOR POLYEPOXIDES, ESPECIALLY EPOXY RESINS. MANY OF THEN ALSO HAVE LOW VISCOSITY, LOW TOXICITY AND LOW TENDENCY TO SKIN AND EYE IRRITATION.
