摘要:
A reinforced polyolefin article is provided which includes a sized reinforcement material incorporated in the article. The article may be prepared by polymerizing a cyclic olefin monomer in the presence of the sizing agent and a metathesis polymerization catalyst which includes ruthenium or osmium.
摘要:
A metathesis polymerized polyolefin article is provided which includes a flame-retarding agent. The method of making the article includes polymerizing an olefin monomer via a metathesis polymerization reaction in the presence of a one-part metathesis polymerization catalyst and a compatible flame-retarding agent.
摘要:
A linerless tank structure has a body that defines an enclosed interior volume. The body has a cylindrical section having an axis of symmetry and a dome section coupled with the cylindrical section. The construction of the pressure vessel includes multiple fiber plies. At least one of the fiber plies is a helical ply having fibers traversing the dome helically about the axis of symmetry. At least a second of the fiber plies is a braided or woven ply.

A polymeric nomadic liquid crystal material has both a non-linear optical (NLO) response and also poling orderability, said material having semi-flexibility along the polymer backbone and stereo-regular, like-orientated incorporation in the polymer backbone of (a) a plurality of NLO elements and (b) dipolar elements, wherein the like orientation can be retained, and reversed by an applied poling field, by migration of dipole-reversing molecular defects along the backbone.
摘要:
A disc shaped ratchet wrench device has an outer concentric member disposed at the outer circumference and formed substantially concentrical to a center of the disc shaped ratchet wrench device. The device further has an inner member disposed within the outer concentric member. The inner disc has a driving element rigidly affixed to the center of the disc shaped ratchet wrench device. Whereby, when the outer concentric member is rotated, the inner member and the driving element rotate in conjunction with the outer concentric member for tightening or loosening of a work piece.
摘要:
The present invention is directed to a seal system for sealing a storage tank such as a liquid or air storage tank. In accordance with the preferred embodiment, the seal system includes a radial valve body that is disposed within a circular spring energizer, together which are disposed within a boss member. The spring energizer and the boss member are separated by a non-bonded liner. Various radial seal members are placed within the inner surface of the boss member to ensure the seal, and the seal system is installable to the top portion of a liner of a storage tank.
