  • Patent number: 10214613
    Abstract: The invention relates to a polyester resin which is based on at least one fatty acid, with zero oil length (0%) or an oil length of between 0 and 35%, with a weight ratio of oxidizable fatty acids (monoacids), relative to the overall fatty acids, of 0 or greater than 0 and ranging up to 1, and which is based on an acid component comprising, in addition to the fatty acid, from 30% to 85% by weight, relative to the total weight of said resin, of rosin and/or of derivatives thereof bearing at least one carboxylic acid function.
    Type: Grant
    Filed: March 8, 2017
    Date of Patent: February 26, 2019
    Assignee: Arkema France

  • Publication number: 20130197152
    Abstract: The invention relates to a polyester resin which is based on at least one fatty acid, with a zero oil length (0%) or an oil length of between 0 and 35%, with a weight ratio of oxidizable fatty acids (monoacids), relative to the overall fatty acids, of 0 or greater than 0 and ranging up to 1, and which is based on an acid component comprising, in addition to said fatty acid, from 30% to 85% by weight, relative to the total weight of said resin, of rosin and/or of derivatives thereof bearing at least one carboxylic acid function. The resin of the invention is used as binder in coatings and in particular in water-based coatings such as paints, varnishes and surface coatings, in the form of an aqueous dispersion of resin, with particular performance in terms of aqueous dispersibility, development of hardness over time in the absence of siccativating agent during drying, and of resistance to yellowing and to water.

  • Patent number: 5089751
    Abstract: This invention relates to fluorescent lamp controllers and dimming controls for use therewith and more particularly to the provision of a dimming control which provides protective isolation between input terminals and lamp energizing circuitry and which facilitates accurate and safe control of light intensity over a wide range. The invention provides dimming controls which are efficient and highly reliable and are readily and economically available.

    Date of Patent: February 18, 1992
    Assignee: North American Philips Corporation
    Inventors: John M. Wong, Michael A. Kurczak
  • Patent number: 5003230
    Abstract: A fluorescent lamp controller uses a dimmer circuit having an isolation transformer. The controller applies a high frequency current to the primary winding of the transformer. The secondary winding is coupled to a control input via loading circuitry. A detector circuit supplies a signal to the lamp controller indicative of the resultant loading of the transformer to control lamp intensity.
