  • Patent number: 9481016
    Abstract: Methods, systems, and articles of manufacture to combine mail streams in a binding line are disclosed. An example method includes analyzing a mailing list including a plurality of addresses. The example methods also includes associating a primary book with a first set of the addresses and associating a secondary book with a second set of the addresses. In addition, the example method includes creating multiple primary books on a production line and depositing multiple secondary books in the production line.
    Type: Grant
    Filed: October 29, 2014
    Date of Patent: November 1, 2016
    Assignee: R. R. Donnelley & Sons Company
    Inventors: Chris Brown, David L. Drummond

  • Patent number: 8880214
    Abstract: Methods, systems, and articles of manufacture to combine mail streams in a binding line are disclosed. An example method is used to create a first book on a production line, where the first book is associated with a first recipient address. The example method is then used to deposit the second book associated with a second recipient address via a book feeder on the first book as the first book moves along the production line.

  • Publication number: 20030127391
    Abstract: A method for the treatment of circulating cooling water to remove undesirable chemical, particulate and biological components to minimize fouling, scaling and corrosion. A saturated solution of calcium carbonate is maintained in a cross flow filtration system by controlling the concentration of precipitated salts, temperature and/or pH. The turbulent agitation of the water circulating in the cross flow filtration loop encourages the precipitation of the dissolved calcium carbonate from the saturated solution. The concentration of particulates in the cross flow filtration loop is controlled with respect to the filter membrane flux by balancing the rate of withdrawal of concentrate against the rate of addition of feed water from the circulating cooling water. Additionally, chemicals may be added to the circulating cross flow filtration loop to precipitate other dissolved chemicals. The cross flow filter may be a microfilter or a nanofilter.

  • Patent number: 6210078
    Abstract: The invention relates to a method for removing a contaminant in situ from soil containing the contaminant, by contacting the soil containing the contaminant with a reagent in situ to remove the contaminant from the soil and form a mixture; removing the mixture from the soil; and removing the contaminant from the mixture, wherein the reagent is not citric acid. The invention further relates to a method for removing a contaminant in situ from soil containing the contaminant, by contacting the soil containing the contaminant with a reagent in situ and mobilizing the contaminant by electroremediation to form a mixture containing the contaminant; and removing the contaminant from the mixture.

  • Patent number: 5043106
    Abstract: A process for making optical mirrors which includes making a rough plaster casting to about the desired shape of the mirror, with the casting having a rough surface, and then applying successive thin layers of polyester resin to the surface of the rough casting to form a finished casting having a smooth coated surface suitable for use as an optical mirror.
