Abstract:
The present invention concerns a reactive carrier that forms no by-products during melt injection of polymer into articles such as sheets, films, fibers and containers. The reactive carrier is used to mix additives into the polymer resin. More particularly, the invention relates to the use of one or more cyclic anhydrides or substituted cyclic anhydrides as the reactive carrier. The polymer can be polyester or polyamide. Suitable cyclic anhydrides are those with a melt point of less than the polyester or polyamide, preferably less than about 160 °C, and more preferably less than about 125 °C. Most preferable are cyclic anhydrides with a melt point less than about 100 °C and especially suitable are those that are liquid at room temperature (25 °C). The cyclic anhydride may be selected from the group of succinic anhydride, substituted succinic anhydride, glutaric anhydride, substituted glutaric anhydride, phthalic anhydride, substituted phthalic anhydride, maleic anhydride, substituted maleic anhydride, or mixtures of two or more of these.
Abstract:
A textile package production system includes an imager, a transporter, a sorter, and a controller. The imager is configured to generate an optical image for a textile package. The imager has at least one optical detector and an optical emitter. The imager has an inspection region. The transporter has a test subject carrier configured for relative movement as to the carrier and the inspection region. The sorter is coupled to the transporter and is configured to make a selection as to a first classification and a second classification. The controller has a processor and a memory. The controller is coupled to the imager, the transporter, and the sorter. The controller is configured to implement an artificial engine classifier in which the sorter is controlled based on the optical image and based on instructions and training data in the memory.
Abstract:
Methods for increasing carbon-based chemical product yield in an organism by genetically modifying one or more genes involved in a stringent response and/or in a regulatory network, nonnaturally occurring organisms having increased carbon-based chemical product yield, and methods for use in production of carbon-based chemical products are provided.
Abstract:
Provided herein are systems and methods for recycling and supplementing off-gas from a gas fed reaction process. The systems and methods are particularly useful for bioprocesses that convert hydrogen gas into one or more biosynthetic products. By maintaining separate hydrogen and oxygen feed gas streams, and forming a recycle gas that introduces a target component of the supply gas to the bioreactor within a target concentration range, the yields, productivities, and safety profiles of the bioprocess can be enhanced.
