  • APPARATUS FOR TESTING BENDING STRENGTH
    Publication number: 20070209448
    Abstract: An apparatus for testing bending strength is provided. The apparatus includes a frame, a motor, and a control part. The frame includes an impingement board. The motor includes a piston. A piston head is mounted on an end of the piston for impacting the impingement board. The piston head defines a space configured for receiving a hand-held device. The control part is for controlling the piston to move up and down repeatedly. The apparatus can be used to test a hand-held device's bending strength conveniently.

  • High solids, pumpable aqueous compositions of high monoalkyl phosphate ester salt content
    Patent number: 6262130
    Abstract: Stable, pumpable aqueous surfactant compositions of water and alkyl phosphate ester salts having a molar ratio of mono- to di- alkyl phosphate esters equal to or greater than 80:20, with the surfactant composition being essentially free of water-soluble alcohol or co-solvent. The pumpable aqueous surfactant compositions have a solids content of about 40% by weight or more and exhibit one or more pumpable regions over a range of pH values for the aqueous surfactant composition.

  • Aqueous dispersion of a surface active polymer having enhanced performance properties
    Patent number: 5686024
    Abstract: The present invention is directed to a new aqueous dispersion of surface active polymer which demonstrates enhanced surface active and performance properties more particularly as a foaming agent. The polymer comprises a vinyl monomer having at least one quaternized nitrogen atom, a vinyl monomer having at least one amide group, a vinyl monomer bearing both a hydrophobic and a hydrophylic group and optionally, a vinyl carboxylic monomer.
