    Abstract: Emulsion paint type damping coatings show an excellent film forming property even if it leaves at low temperature from 5 to 20° C. It does not generate a defective coated film like swellings after baking drying and brings out an excellent damping performance within a range of 20 to 60° C. That is, it contains one or more than two kinds of organic chemicals within a range of 0.5% to 5% by weight in total and the MFT, the minimum film forming temperature of the entire resin emulsion is within a range of 5 to 15° C. and the boiling point for a film forming assistant is within a range of 150 to 240° C., thus, it enables to obtain an excellent film forming property at 5° C. and even in baking drying and does not generate a defective coated film like swellings as well. As a result, emulsion paint type damping coatings bring out an excellent damping performance within a range of 20 to 60° C.

  • Patent number: RE40840
    Abstract: An economical and reliable system for the contained transfer of particulates by means of a series of transfer containers facilitates the particulate transfer without either exposure of the operating personnel and the environment to the particulate, or environmental contamination of the particulate itself. The system employs a multiple o-ring canister assembly which can be attached to either the discharging port or charging port of a piece of processing equipment. The canister has a series of circumferential o-ring grooves which allows the attachment of a series of individual transfer containers. In a charging mode, once the particulate is charged to the processing equipment, a first transfer container is collapsed and a second transfer container is placed in the next o-ring groove, thereby containing the remaining contaminated section of the first transfer container. The first transfer container is removed through a bag-out sleeve which is an integral part of the second transfer container.
