Abstract: A robotic electrostatic painting system includes a barrier formed from an electrical insulating material and disposed between adjacent reservoirs for holding a conductive paint used in an electrostatic painting operation. The barrier is shaped and dimensioned with a central plate and upper and lower flanges to block every straight line path between the reservoirs to electrostatically separate the reservoirs and prevent the formation of a ground path or short circuit when there is a voltage difference between the reservoirs. The electrostatic separation of the reservoirs further prevents deterioration of conductive components of the robotic electrostatic painting system.

Abstract: In a method for connecting an attachment part to a structural part of a bodywork, a wall of the structural part is formed to at least partly encircle a region of the structural part. A form element is arranged to a main body of the attachment part. The attachment part is placed in the region of the structural part such that the form element touches the wall of the structural part, and the attachment part is pushed into the region, thereby causing the form element to move in relation to the main body of the attachment part until reaching an aperture in the wall of the structural part so that the form element moves into the aperture and is arranged therein to thereby position the attachment part in the region of the structural part.

Abstract: A plastic film for use as a temporary vehicle seat cover to be installed by an automotive manufacturer. The seat cover protects the vehicle's seat from dirt before the vehicle is purchased by a consumer. The plastic film also has minimal acoustic properties so that the vehicle seat does not interfere with routine automotive acoustic testing known as the Buzz, Squeak, and Rattle test. The plastic film also has a high degree of visual clarity to allow a potential consumer to view the vehicle's seat. The plastic film further has a differential of the coefficient of friction on the opposed sides of the film to minimize movement and noise of the film when a driver is in the vehicle.

Abstract: Durable icephobic materials form anti-ice coatings on a variety of substrates, including for aircraft, powerlines, vehicles, marine structures, communications towers, outdoor equipment, and the like. The icephobic may comprise an elastomeric polymer with a low crosslink density (e.g., ?1,300 mol/m3) and low initial ice adhesion strength (e.g., ?ice?100 kPa prior to exposure to icing conditions). Further, the icephobic material maintains ?ice after 10 icing/deicing cycles that is ?50% of the initial ?ice Introducing optional miscible liquids enhances interfacial slippage of chains in the elastomeric polymer. The low ?ice levels minimize ice buildup and eliminate necessary work to remove any accumulated ice via passive removal during normal operation. Other icephobic materials include linear polymers with plasticizers distributed therein or PDMS-silane coatings, both of which are free of any layers of surface liquids. Methods of making such icephobic materials are also provided.

Abstract: The present invention provides a semi-product made of a prepreg, a three-dimensional preform and an overmolded part. More particularly, the present invention provides a semi-product made of a prepreg, including at least a first prepreg layer and a second prepreg layer, characterized in that a magnetic material layer is laid between the first prepreg layer and the second prepreg layer. Since the magnetic material layer is added between the prepreg layers, the produced semi-product, when being made into a three-dimensional preform and further into an overmolded part, can be well supported and positioned due to attraction to the magnetic material layer by the magnet on the die, and therefore be precisely shaped.
