Abstract: Methods and apparatus for modulo 2 addition based encryption by block substitution techniques which allows use of the substitution scheme with relatively simple hardware. The block substitution, a one to one mapping of n bit binary numbers onto themselves, is based on the fact that certain permutations of the n bit binary numbers define a block substitution by modulo 2 addition of one permuted set of numbers to another, and that a subset of these define equations having an additive relationship when viewed as vectors. This allows the simple changing of the transformation on a frequent basis. Various properties of the transformations and methods of using the same are disclosed.

Abstract: Syndiospecific catalysts and processes for the syndiotactic propagation of a polymer chain derived from an ethylenically unsaturated monomer which contains 3 or more carbon atoms or is a substituted vinyl compound. The catalysts comprise an unbalanced metallocene cation, characterized by a cationic metallocene ligand having sterically dissimilar ring structures joined to a positively charged coordinating transition metal atom, and a stable noncoordinating counter anion for the metallocene cation. One of said ring structures is a substituted or unsubstituted cyclopentadienyl ring and the other of the ring structures is a substituted cyclopentadienyl group which is sterically different from the first cyclopentadienyl group. A structural bridge between cyclopentadienyl groups imparts stereorigidity to the catalyst. The catalyst is contacted with a C3+ alpha olefin or other ethylenically unsaturated compound in a polymerization reaction zone and maintained in contact with the catalyst in the reaction zone under polymerizatio conditions to produce a syndiotactic polymer.

Abstract: A fiber blending system includes an apparatus and method of forming a mat of cellulosic fibers and synthetic fibers, as well as a mat thereby formed. The method includes the steps of fiberizing cellulosic material into cellulosic fibers in a fiberizer, volumetrically metering a metered amount of synthetic fibers, and injecting the metered amount of synthetic fibers into the cellulosic fibers. The cellulosic fibers are blended with the metered amount of synthetic fibers in a blending chamber to form a fiber blend. The fiber blend is dispersed through a fiber disperser having apertures of a preselected size and shape to provide a dispersed fiber blend. A third type of fiber may also be mixed with the dispersed fiber blend. The dispersed fiber blend is collected as a mat on a fiber collector to provide a mat of blended cellulosic and synthetic fibers. The mat may be thermobonded by a thermobonder and sandwiched between a facing sheet and a backing sheet. By varying the aperture preselection, as well as the size and type of fibers, a bonded mat having desired mat characteristics is formed.

Abstract: A method for processing scanned code data, including a plurality of strings, to determine whether the scanned code data is part of a valid code begins by examining a first string of a first scanned code data. A cluster is opened with the first string if the first string contains a start pattern. At least one valid middle portion of the first string is identified and a transition position count associated with the at least one valid middle portion is stored. A second scanned code data is searched for a second string matching at least part of the first string in the cluster. If a match is found, then the second string is added to the end of the cluster. The cluster is closed upon detection of a stop pattern and is then decoded.

Abstract: The invention relates to a process for the production of high-molecular-weight polytetramethylene adipamide from equivalent amounts of 1,4-diaminobutane and adipic acid at lower pressures. By supplying 1,4-diaminobutane at an advanced stage of the polycondensation a first polycondensate is obtained that can be extruded very well and that can be aftercondensed in the solid phase to obtain a product with a high molecular weight within a short time. Because of this a substantial overall gain in time is realised. It even appears to be possible to prepare a first polycondensate with a relative viscosity that is high enough for the polycondensate to be further processed into shaped objects. The polycondensation can be carried out both in the melt and in solution. The diaminobutane can be supplied both via the liquid and via the vapour phase.

Abstract: A speech signal coding system for coding a speech signal at a bit rate of 8 to 4 kb/s wherein the mount of calculation in fractional search of delays of an adaptive codebook (180) is reduced significantly. Before a fractional delay of the adaptive codebook (180) is found. candidates of integer delay are found by an open-loop using correlation values. A search of a fractional delay by a closed loop is performed for a search range for fractional delays which is provided by several samples of each integer delay candidate thus found using the correlation values. The fractional delay search is realized by polyphase filtering of excitation signal in the past. In the search, a plurality of candidates of fractional delay may be found for each integer delay candidate from the adaptive codebook (180). In this instance, a fractional delay is determined decisively from the decimal delay candidates after a search of an excitation codebook(200). <IMAGE>

Abstract: An apparatus is presented for economically making crystallized glass products from waste ash produced from the sewage sludge dewatered by organic matters, which is usually regarded to be difficult to process. The melting is performed in two furnaces: the primary melting furnace and the secondary melting furnace. The primary furnace melts waste ash and the primary melt is charged into the secondary melting furnace. The glassy material produced in the secondary melting furnace is charged into a crystallization furnace to convert the glassy material to a crystallized glass product. This basic configuration of the apparatus allows the production of either irregular shaped crystallized products, such as crushed stone like products, or crystallized manufactured products, such as tiles and blocks, depending on the combination of processing equipment and their operating conditions. The apparatus enables the production of crystallized glass products from waste ash feed economically, because of the flexibility and versatility in the design of the apparatus. <IMAGE>
