Abstract: A shield (3) is mounted in the driver's side window frame (7) of a vehicle by a lower support (5) containing a flat spring (49) which releasably pushes the shield against the upper window frame. A stand-off (17, 18) at the upper end of the shield spaces other portions the upper edge of the shield from the window frame. A shield handgrip (9) is angled 45° with respect to a lower edge of the shield, to permit the shield to be carried with one apex of the shield up.

Abstract: The invention provides liquid electrographic toner compositions comprising a liquid carrier having toner particles and at least one soluble polymer dispersed in the liquid carrier. The liquid carrier has a Kauri-Butanol number less than about 30 mL. The toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The soluble polymer is present in an amount of from about 1% to about 10% by weight based on toner particle weight. The absolute difference in Hildebrand solubility parameters between the soluble polymer and the liquid carrier is less than about 3.0 MPa1/2. In one aspect of the invention, the soluble polymer that is incorporated in the toner composition has no more than about 30% weight ratio chemical constitution variance from the chemical constitution of the S material portion of the amphipathic copolymer.

Abstract: Electrophotographic ink compositions display reduced malodor effects when at least one antagonistic odor vector compound for C10, C11 and C12 hydrocarbons is present in the ink composition. The use of appropriate amounts of the antagonistic odor vector compounds for C10, C11 and C12 hydrocarbons does not adversely affect the functional imaging properties of the ink.

Abstract: A method and apparatus of the invention includes a method of removing airborne hydrocarbons from liquid electrophotographic printer exhaust comprises generating airborne hydrocarbon droplets as either vapor or mist during the transportation of electrophotographic ink or toner, directing substantially all of the air and hydrocarbon droplet mixture to a central collection point, forcing the air/droplet mixture to and through an oleophilic, substantially non-leaching collection media, and exhausting substantially hydrocarbon-free air from the electrophotographic printer. The method may further comprise inducing pressure in the printer with air pressure reduction to pull the exhaust through the collection media, for example with a pump or fan used to produce air pressure reduction. The method may comprise inducing airflow in the printer with ventilation holes or by the addition of a fan to provide a fresh air inlet. The air/hydrocarbon mixture may be directed to the collection media by a transportation system.
