  • Charge control agents for toner compositions
    Patent number: 8101328
    Abstract: The present disclosure provides polymer-ionic complexes useful as charge control agents. Such charge control agents may be utilized with toner particles to impart excellent triboelectric charging characteristics to the toner.

  • Motorcycle protective cover
    Patent number: 6951361
    Abstract: A flexible protective cover which attaches over the forward surfaces of a motorcycle. The protective cover includes a central portion and two attached side flaps. The central portion fits over the forward surfaces of the upper cowling. The two side flaps fit over the sides of the lower cowling. The cover's upper portion is attached by slipping adjustable tabs around the stalks of the rear view mirrors. The lower portion is attached around the radiator opening. The trailing edges of the two side flaps may also be attached to the lower cowling. The invention optionally includes an integrated fender cover which slips over the motorcycle's front fender and lock around the two struts supporting the front wheel. With this device installed, all the forward-facing painted surfaces are protected from bug strikes and the like.

  • Toner and developer providing offset lithography print quality
    Patent number: 6365316
    Abstract: A toner for particular use in devices utilizing hybrid scavengeless development includes toner particles of at least one binder, at least one colorant, and optionally one or more additives, the toner exhibiting a charge per particle diameter (Q/D) of from −0.1 to −1.0 fC/&mgr;m with a variation during development of from 0 to 0.25 fC/&mgr;m and the distribution is substantially unimodal and possesses a peak width of less than 0.5 fC/&mgr;m, and the toner has a triboelectric charge of from −25 to −70 &mgr;C/g with a variation during development of from 0 to 15 &mgr;C/g following triboelectric contact with carrier particles. Use of a toner with such properties in a hybrid scavengeless development apparatus enables images to be achieved with properties similar to that achieved in offset lithography.
