    摘要： A linear friction welding system includes a power shaft defining a power shaft axis and including a first eccentric portion and a first power transfer portion, a power transfer rod engaged with the first power transfer portion, an actuator assembly operably coupled with the power transfer rod and configured to move the power transfer rod axially along the power shaft axis, a crank including a second eccentric portion operably coupled with the first eccentric portion, and a second power transfer portion engaged with the power transfer rod, the linear friction welding system configured such that axial movement of the power transfer rod causes rotational movement of the crank with respect to the power shaft about the power shaft axis, a cam follower operably connected to an outer surface of the second eccentric portion, and a ram operably connected to the cam follower and configured to vibrate along a welding axis.

    摘要： A copolymer comprises at least two repeating units of formula I In this formula each R1 is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo; each Y is independently an alkylene, aralkylene, or a combination thereof; each G is independently a bond or a divalent residue equal to a diamine of formula R3HN-G-NHR3 minus the two —NHR3 groups; each R3 is independently hydrogen or alkyl or R3 taken together with G and to the nitrogen to which they are both attached form a heterocyclic group; each n is independently an integer of 0 to 1500; each p is independently an integer of 1 to 10; and each q is independently an integer of 1 or greater, and wherein at least 50% of the q's are the integer 2.
