The invention provides a process for recovering polyester polymers, particularly polyethylene terephthalate (PET) from a mixed polymer recycle stream, typically in the form of carbonated soft drink or other containers. This process comprises: (1) contacting the mixed polymer recycle stream with a solvent which selectively dissolves the polyester, (2) separating the selective solvent containing PET...

Stable emulsions based on unsaturated polyetherester resins are disclosed. The emulsions have high stability compared with conventional emulsions that are based on unsaturated polyester resins. The invention includes base-stabilized emulsions, as well as emulsions containing fillers or functional additives. The emulsions, which are storage stable for weeks or months, are useful for making water-ex...

There is now provided a polyisocyanate-based foam made by reacting an organic polyisocyanate with a polyol solution containing a C4 -C7 aliphatic and/or cycloaliphatic hydrocarbon as a blowing agent. The hydrocarbon blowing agent is soluble in the polyol solution having polyols with polyester linkages by using a reacted or unreacted compatibilizing agent represented by the formula: wherein R...

The method and apparatus function to form three-dimensional imagery on plural screen surfaces (2) which are formed by changing planes of imagery. One or more projectors (4) project a plurality of images onto the screen surface from a common axis. The planes of imagery on the screens (2) which are projected by said one or more projectors (4), change at such a speed that, to the eye, the images appe...

A microphone selection process uses combination values derived in a manner which provides an indication of which one of a plurality of microphones (220-1...220-5) that provides area coverage for a conference room best receives the speech signal. The process selects the microphone which best receives the speech signal by comparing a signal energy value received in each one of the microphones to tha...

A method and device for enhancing the vapor sterilization of the lumen of medical instruments and like articles under reduced pressure. A vessel containing a small amount of a vaporizable liquid antimicrobial solution is attached to the lumen. The antimicrobial vaporizes and flows directly into the lumen of the article as the pressure is reduced for the sterilization cycle. Preferred embodiments i...

A method and apparatus for recovering fiber useful for papermaking from an effluent stream includes a primary process for treating an effluent stream to separate usable fiber from contrary matter, and secondary operations, supplementing the primary process, to treat the contrary matter rejected by the primary process to recover usable fibers contained in the reject matter. In addition, the seconda...

Binary azeotropes and azeotrope-like compositions contain n-butyl lactate, n-propoxypropanol, 1-butoxy-2-propanol, 1-butoxy-2-ethanol or 4-methylcyclohexanol with octamethylcyclotetrasiloxane and are useful for cleaning, rinsing or drying.

In a communication system in which data and user information are transmitted on a radio path between a transmitting end and a receiving end, multirate coding and detection are carried out by: allocating different signal waveforms to different transfer rates, selecting, at the transmitting end, the data transfer rate to be used on the radio path for transferring user information, selecting, at the ...
