  • Patent number: 7096084
    Abstract: Disclosed are methods for evaluating the environmental impact of various chemical components as a function of their proposed functional use in a chemical product, methods for formulating products based on those evaluations, and databases for assisting in those methods. Consumer products can be environmentally improved using these methods. Environmental criteria are in part developed based on the nature of the ultimate use of the product, and usually vary for a given chemical between types of proposed uses. The environmental classes for components are adjusted by their weight representation in the final product.
    Type: Grant
    Filed: August 30, 2005
    Date of Patent: August 22, 2006
    Assignee: S.C. Johnson & Son, Inc.
    Inventors: David C. Long, Frederick H. Martin, John A. Weeks

  • Patent number: 5152221
    Abstract: A doctor blade, for removing excess ink from a gravure cylinder, comprises first and second blade sections formed of flexible metal. The blade sections are joined by a rigid, slotted coupling member so as to lie at a substantial angle to each other. The first blade section contacts an upwardly moving section of the cylinder at an angle of from 65 to 90 degrees. The second blade section is mounted in a cantilever manner to accommodate resilient deflection of the first blade section. The first blade section is thus maintained in substantially uniform pressure contact with the cylinder while at the same time being disposed at a relatively large angle to the surface of the cylinder for optimum doctoring effectiveness.
