  • Process for polymerization of itaconic acid
    Patent number: 5223592
    Abstract: Polymers of itaconic acid are formed at high conversion by adding completely neutralized monomer solution and initiator solution to a vessel initially containing water at a temperature sufficient for polymerization. These polymers are biodegradable and are most useful as detergent additives, scale inhibitors and removers, sequesterants, yarn sizers, deflocculating agents, de-inking agents, suspending agents and dispersing agents.

  • Soldering method and tool
    Patent number: 5127572
    Abstract: The method of the invention comprises the steps of locating the integrated circuit so that the projecting ends of the pins thereon are in juxtaposition with the corresponding connector pads on the printed circuit board; and applying solder to the connector pads with a heated soldering tool moving over the pads and touching the projecting ends of the pins on the integrated circuit without overlying the pins to solder the projecting ends of the pins to the connector pads.
