Abstract: An additive system for polyester polymers comprising an effective amount of (i) a fatty acid amide selected from the group consisting of oleyl palmitamide, ethylene bis stearamide, ethylene bis oleomide, and stearyl erucamide; (ii) a partially or fully calcined porous poly(methylsilsequioxane); and (iii) a stabilizer comprising a primary and a secondary antioxidant.

Abstract: Bottles, containers and other articles are formed from polypropylene compositions that include a reheating agent, such as antimony, carbon black, graphite, titanium, copper, manganese, iron, tungsten, graphite, infra-red absorbing dyes or other infra-red absorbing material. The reheating time for the polypropylene composition is shortened for injection stretch blow molding or thermoforming, and the polypropylene granule composition with reheating agent has an L* value of at least 80% of the L* value for a polypropylene granule control without added reheating agents as measured by the Gardner color test. The reheating agent may be incorporated into the polypropylene composition by in situ chemical reduction of a metal compound, such as antimony triglycolate, with a reducing agent, such as hypophosphorous acid. In addition, the polypropylene composition with reheating agent may be derived from a polypropylene masterbatch with high concentrations of reheating agent.

Abstract: A power line communication system. The system includes at least one transmitter for generating and transmitting signals over a power line and at least one receiver for the receipt of signals transmitted over the power line. The transmitter and receiver(s) devices include a storing mechanism containing the address of the device and a programming port for electrical connection to a mating connector of a programmer. The programmer also includes a selector for selection of a desired address such that the address of the addressable device may be changed by the programmer. The transmitter also includes a timing mechanism for automatically retransmitting signals over the power line and the receiver includes a time measuring mechanism for ascertaining whether a signal has been received within a predetermined time period and a mechanism for setting the receiver in a default state should no signals be received within that time period.

Abstract: In a compression device 100 (FIG. 1), two shafts 4,6 carry double lobed packers 5,101 which force crop through a throat formed by static elements 7,8 into a chamber 9. The packers are intermeshed and angularly displaced around their shafts to reduce the driving torque of the device.
