Abstract: A method of treating an amorphous CBDO polymer to impart self healing and shape memory properties by heat treatment, and products resulting from such method are described. An amorphous CBDO copolymer may include a copolyester prepared by reacting an aromatic dicarboxylic acid or ester or anhydride thereof, a 2,2,4,4-tetraalkyl-1,3-cyclobutanediol and 1,3-propanediol, 1,4-butanediol, or mixture thereof. The method may include heating said copolymer to a temperature above its glass transition temperature to impart self healing and shape memory properties.

Abstract: According to the invention, an amorphous CBDO polymer (as described in U.S. Pat. No. 5,705,575, issued Jan. 6, 1998, which U.S. patent is incorporated herein by reference in its entirety) is imparted self healing and shape memory properties by heat treatment.

Abstract: According to the invention, an amorphous CBDO copolymer (as described in U.S. Pat. No. 5,705,575, issued Jan. 6, 1998, which U.S. patent is incorporated herein by reference in its entirety) is treated to impart high impact resistance, also called impact strength.

Abstract: A fiber reaction process whereby reactive components contained in immiscible streams are brought into contact to effect chemical reactions and separations. The conduit reactor utilized contains wettable fibers onto which one stream is substantially constrained and a second stream is flowed over to continuously create a new interface there between to efficiently bring about contact of the reactive species and thus promote reactions thereof or extractions thereby. Co-solvents and phase transfer catalysts may be employed to facilitate the process.

Abstract: A system and method for remotely measuring the temperature of an object using microwave radiometry that may be used in hostile environments. A single pole-single throw reflective PIN diode switch is operable in a PASS mode and a BLOCK mode. In the PASS mode, the switch passes the power received from the object to a low-noise block converter (“LNB”) for amplification. In the BLOCK mode, the switch blocks the object power and reflects the load noise power of an ambient temperature load to the LNB. A detector diode detects the amplified power output during both the BLOCK and PASS mode and the AC signal from the detector is converted to an output signal proportional to the difference in the noise powers detected in the PASS and BLOCK modes.
