摘要:
Graft copolymers of polybenzazole and poly(phenylene sulfide) are synthesized by the reaction of terephthalic acid and 4,6-diaminoresorcinol with 2-(polyphenylene sulfide)terephthalic acid. The resulting graft copolymer can be cross-linked by heating to provide a cross-linked product having improved thermal stability, acid resistance, and compressive strength.
摘要:
A coating assembly paints a coating on a plurality of articles having first and second article portions. The coating assembly includes a rail frame defining a longitudinal path for the plurality of articles to travel along. An endless chain having a chain portion thereof extending along the longitudinal path transports the plurality of articles along the longitudinal path. The coating assembly also includes a painting station for applying a coat of paint to the first article portion of each of the plurality of articles while preventing the coat of paint from extending to the second article portions of each of the plurality of articles. The painting station includes a plurality of spray nozzles fixedly secured to the rail frame on either side of the endless chain. Each of the plurality of spray nozzles are offset from each other along the longitudinal path such that the first article portions are entirely covered by the coat of paint as the plurality of articles pass thereby.
摘要:
A seat belt retractor (22) having an inertial sensor to initiate lockup of the retractor, the inertial sensor including a first housing portion (102) having an actuating arm mounting member (120). The retractor including a first pin (126) cantilevered from the mounting member (120); an activation arm (130) rotationally supported upon the first pin (126), the activation arm (130), when activated, movable into engagement with a ratchet wheel (80), a pendulous vehicle sensor subassembly (150) mounted upon the first housing portion (102), the subassembly (150) and the first housing portion (102) including a support mechanism to rotatably support the sensor subassembly thereon. The sensor subassembly (150) further including a weighted member (152) having a platform for supporting a movable inertial weight (154), the inertial weight movable on the platform in response to deceleration to which the retractor is subjected; a movable arm (156) supported by the weighted member and including a sensing arm (240) having a tip (202) resting upon the inertial weight (154), the movable arm cantilever supported relative to the weighted member, wherein movement of the movable arm causes movement of the sensing arm thereby causing a change in the elevation of the activation arm thereby placing the retractor in a pre-lock mode.
