  • Patent number: 5698639
    Abstract: The invention provides ethylene-propylene-diene rubbers capable of imparting excellent heat resistance, weather resistance and dynamic fatigue resistance to vulcanized rubbers made therefrom. The ethylene-propylene-diene rubbers have sulfur uniformly dispersed therein by mixing a solution of the sulfur with a solution of the ethylene-propylene-diene rubber prior to the addition of vulcanization accelerators or other rubber additives to the rubbers. The vulcanized rubbers are particularly suitable for use as automobile components which require dynamic fatigue resistance such as muffler hangers, belts, rubber vibration insulators, engine mounts, tire treads for pneumatic tires, sidewalls for pneumatic tires and white sidewalls.

  • Patent number: 5695964
    Abstract: This invention relates to novel vectors and host cells containing nucleic acids coding for a polypeptide having thrombin binding ability, anticoagulant activity and thrombolytic activity. The polypeptide can be efficiently produced in large quantities by means of genetic recombination techniques using the vectors and host cells of the present invention. Since the polypeptide exhibits anticoagulant activity and thrombolytic activity without generating side effects such as bleeding tendencies, it can be applied effectively to the prevention and treatment of hypercoagulability-related diseases.

  • Patent number: 5695958
    Abstract: A method is described for isolating an exogenous polypeptide in a non-native conformation from cells, such as an aqueous fermentation broth, in which it is prepared comprising contacting the polypeptide with a chaotropic agent and preferably a reducing agent and with phase-forming species to form multiple aqueous phases, with one of the phases being enriched in the polypeptide and depleted in the biomass solids and nucleic acids originating from the cells. Preferably, the method results in two aqueous phases, with the upper phase being enriched in the polypeptide.

  • Patent number: 5691391
    Abstract: A variable pitch fan for a helicopter equipped with a NOTAR.RTM. mechanical antitorque directional control system comprises a plurality of blade assemblies. Each blade assembly includes a blade portion, which is molded from a blended material which includes fiber reinforced polypropylene. A key to the invention is the use of long fibers, having a length of at least approximately one-half inch, for reinforcement, the long fibers providing for about twice the pull-out strength of short or chopped fibers. Another key aspect of the invention is the use of a blowing agent in the blended material, which serves to reduce weight and warpage by creating a foamed structure having a variable density, the structure retaining considerable strength because of the fiber reinforcement. The blade portion is molded about a spar which has holes therethrough, the holes providing a mechanical interlock between the blade and the spar.
