  • Patent number: 6330885
    Abstract: An implant device which includes a structure implantable within a living animal and a sensor included as part of the structure. The sensor is operatively configured to detect accretion of biological material on the sensor by producing an output which varies as a function of the accretion of biological material on the sensor. A communication element is further included as part of the structure and is operatively coupled to the output of the sensor. The communication element is configured to communicate information based on the output of the sensor wirelessly to a remote element located outside the living animal.

  • Patent number: 6306945
    Abstract: The present invention relates to a halogen containing polymer compound containing a modified zeolite stabilizer. The modified zeolite stabilizer has a small particle diameter, narrow particle size distribution and less than 10 weight percent water. The modified zeolite stabilizer is formed by shock annealing, coating or a combination of the two methods.

  • Patent number: 6277922
    Abstract: Chlorinated polyvinyl chloride (CPVC) is prepared from polyvinyl chloride (PVC). When PVC is made utilizing polyvinyl alcohol, the low molecular weight CPVC compound so prepared is colored. A low molecular weight CPVC compound prepared from PVC that was made in the presence of a cellulose ether instead of polyvinyl alcohol resulted in a very low color compound having a DE of O by definition. However, a CPVC compound prepared from PVC made in the presence of polyvinyl alcohol resulted in a relatively high color (DE 18.51). During the polymerization of vinyl chloride, polyvinyl alcohol is replaced with the hydroxypropylmethyl cellulose ether having a methoxyl substitution of 15-35 percent and a hydroxypropoxyl substitution of from 4-35 percent.

  • Patent number: 6277915
    Abstract: Block chlorinated polyolefins are disclosed as performance enhancer of high rubber graft copolymers or chlorinated polyethylenes impact modifier in PVC and/or CPVC resins. The block chlorinated polyolefins (e.g. block chlorinated polyethylene) provide good dispersion of the impact modifier particles in the matrix and better adhesion between the impact modifier and the PVC and/or CPVC interface, providing better physical properties such as impact strength as measured by Notched Izod than did the randomly chlorinated polyolefins, often used as processing aids and as impact modifiers in PVC or CPVC. The differences in properties achieved with block chlorinated polyolefins versus randomly chlorinated polyolefins are attributed to the individual blocks of the blocky polyolefin being compatible with either the impact modifier or the PVC/CPVC resulting in better adhesion between phases.
