Granted: 2002-10-29
Abstract: -33-   Apparatus for fabricating discrete segments of cushioned web material for use as dunnage. The apparatus includes a mobile supply cart having at least one substantially horizontal support arm for receiving the hollow core of rolled web material. The apparatus also includes a separate driven rugation device with feed rollers for directing multiple plies of the web material in overlying, contacting relationship slang a single path of travel. The separate cart and rogation device may be removably interconnected for lateral alignment. Driven interdigitized texturing rolls downstream of the feed rollers emboss a raised pattern on the web material, and a plurality of separating rollers downstream from the texturing rolls separate the plies of web material and direct them in divergent paths of travel. Combining rolls recombine the plies of textured web material such that the embossed areas of each ply do not directly overlie each other but are offset, creating void areas between the adjacent plies.  A driven cutter downstream of the combining rolls severs the recombined offset embossed plies into discrete segments. The cutter may have a rotating disc blade with a peripheral edge which moves transverse to the longitudinal length of the plies to cut the plies.   Last, driven exit rollers conveythe cut segments of material from the rugation device.

Abstract: This invention relates to a novel ornithine carbamoyl transferase (OCTase) gene, a recombinant DNA containing the OCTase DNA, a transformation system for a basidiomycete, and production of useful proteins using the system.      More particularly, this invention relates to the OCTase gene of Coriolus hirsutus to afford an efficient host-vector system in basidiomycetes (particularly a white rot fungus such as Coriolus hirsutus IFO 4917) for the preparation of useful proteins. OCTase is the enzyme to transform ornithine to citrulline in arginine biosynthesis in organisms. The present invention provides the OCTase genes of C. hirsutus, the useful Arg~ auxotrophic mutant of C. hirsutus deficient in the OCTase gene, the efficient condition for the preparation of protaplasts and the transformation of the mutant with the cloned OCTase gene and the recombinant DNA's including a promoter, a signal peptide-coding DNA and a protein-coding DNA, the construction of the navel host-vector system of C. hirsutus, and the new method of a large scale preparation of useful proteins using this novel host-vector system with a new recombinant DNA technique.      Furthermore, this invention provides a highly efficient method to produce a useful protein such as lignin peroxidase which is difficult to produce by the conventional method.

Abstract: An improved arc furnace regulator employs neural circuits (100) connected in a multi-layer network configuration with various weighted relationships between the successive layers which are automatically changed over time as a function of an error signal (?) by means of the back-propagation method so that the regulator gradually improves its control algorithm as a result of accumulated experience.  The network is implemented in software which can be developed and run on a PC with extra co-comput-ing capability for greater execution speed.  A second trainable neural network (480) which emulates the arc furnace (120) is used to develop the error signal (?), and is trained in mutually exclusive time periods with the training of the regular network.
