  • Patent number: 11155414
    Abstract: A machine for assembling rebar cages includes a support frame, axial rollers mounted to the support frame for rotatably supporting a cylindrical wire cage for axial rotation about an axis of elongation, a carriage movably mounted to the support frame for translation, with the carriage adapted for driving an elongate rebar rod in a first axial direction. A drive mechanism is mounted to the support frame for driving the carriage in translation back and forth between a retracted position and an extended position for driving rebar rods into the rebar cages for assembly.
    Type: Grant

  • Patent number: 10093839
    Abstract: Disclosed herein are compositions comprising a first copolymer derived from monomers comprising a (meth)acrylate monomer, an acid monomer, and optionally at least one additional monomer selected from the group consisting of styrene, ?-methyl-styrene, vinyl toluene, and mixtures thereof, wherein the first copolymer is derived in the absence of a molecular weight regulator and wherein the first copolymer has a weight average molecular weight of less than 10,000 Daltons, and methods of making the same. The compositions and methods disclosed can be used, for instance, in pressure-sensitive adhesive applications.

  • Patent number: 9238699
    Abstract: Styrenic (meth)acrylic oligomers that are prepared at lower temperature than conventional solid grade oligomers, or are hydrogenated, contain fewer terminal vinylic unsaturations, when compared to such conventional styrenic (meth)acrylic oligomers prepared by the customary high temperature processes. Styrenic (meth)acrylic oligomers that contain fewer terminal vinylic unsaturations demonstrate improved thermal stability and may provide improved resistance to UV weathering compared to the conventional and non-hydrogenated styrenic (meth)acrylic oligomers.

  • Patent number: 5424473
    Abstract: A process of preparing diaryl carbonates, such as diphenyl carbonate, and aryl haloformates, such as phenyl chloroformate. The process involves contacting phenol or a substituted phenol with a carbonyl halide, such as phosgene, in the presence of a phosphorus-containing catalyst. The catalyst is selected from alkyl phosphates, aryl phosphites, aryl phosphates, organic phosphinites and phosphinates, organic pyrophosphates, inorganic phosphorous and phosphoric acids, and phosphorus oxides.
