    摘要: The present invention relates to compositions and methods for providing an improved means of modifying asphalt with a polymer. More particularly, this invention provides a crosslinking system to improve the properties of polymer modified asphalt. Compositions of the present invention contain asphalt, a rubber or elastomeric polymer, and a crosslinkable component, particularly a bismaleimide or a bismaleimide in combination with a difunctional crosslinkable monomer.

    摘要: A high-performance piston core including a first piston cylinder and a second piston cylinder, with a piston center longitudinally disposed between and magnetically coupling the first piston cylinder and the second piston cylinder. The piston center is made of high-performance magnetic material, such as Cobalt steel (CoFe), Silicon steel (SiFe), Vanadium/Cobalt steel (Permendur), alloys thereof, or the like. The high-performance magnetic materials exhibit high magnetic permeability and reduce the magnetic reluctance of flux bottlenecks. In addition, high-performance magnetic materials typically saturate at a higher flux density than the conventional magnetic materials. The first piston cylinder and the second piston cylinder can be made of conventional magnetic material, such as low-carbon steel. The first piston cylinder can include a ring disposed about an end, where the end is longitudinally attached and magnetically coupled to the piston center.
