Abstract: A catalyst is prepared by combining a first compound consisting of a bis(cyclopentadienyl)zirconium compound having one of the following general formulae:Wherein:(A-Cp) is either (Cp)(Cp*) or Cp-A'-Cp* and Cp and Cp* are the same or different substituted or unsubstituted cyclopentadienyl radicals;A' is a covalent bridging group;L is an olefin, diolefin or aryne ligand;Zr is zirconium;X<sub>1</sub> and X<sub>2</sub> are, independently, selected from the group consisting of hydride radicals, hydrocarbyl radicals, substituted-hydrocarbyl radicals, organometalloid radicals and the like;X'<sub>1</sub> and X'<sub>2</sub> are joined and bound to the zirconium atom to form a metallacycle, in which the zirconium, X'<sub>1</sub> and X'<sub>2</sub> form a hydrocarbocyclic ring containing from about 3 to about 20 carbon atoms; andR is a substituent on one of the cyclopentadienyl radicals which is also bound to the zirconium atom. With a second compound comprising a cation capable of donating a proton and a bulky, labile anion containing a single boron atom, and a plurality of aromatic radicals capable of stabilizing the zirconium cation formally having a coordination number of 3 and a valence of +4 which is formed as a result of the combination, said second compound having the general formula:         [L'-H]<sup>+</sup>[BAr<sub>1</sub>Ar<sub>2</sub>X<sub>3</sub>X<sub>4</sub>]<sup>-</sup>Wherein:L' is a neutral Lewis base;H is a hydrogen atom;[L'-H]<sup>+</sup> is a Bronsted acid;B is boron in a valence state of 3;Ar<sub>1</sub> and Ar<sub>2</sub> are the same or different aromatic or substituted-aromatic hydrocarbon radicals which may be linked to each other through a stable bridging group; andX<sub>3</sub> and X<sub>4</sub> are, independently, selected from the group consisting of hydride radicals, halide radicals, hydrocarbyl radicals, substituted-hydrocarbyl radicals, organometalloid radicals and the like. Many of the catalysts thus formed are stable and isolable and may be recovered and stored. The catalysts may be preformed and then used to polymerize olefins, diolefins and/or acetylenically unsaturated compounds either alone or in combination with each other or with other monomers or the catalysts may be formed in situ during polymerization by adding the separate components to the polymerization reaction. The catalyst will be formed when the two components are combined in a suitable solvent or diluent at a temperature within the range from about -100°C to about 300°C. The catalysts thus prepared afford better control of polymer molecular weight and are not subject to equilibrium reversal. The catalysts thus produced are also less pyrophoric than the more conventional Ziegler-Natta olefin polymerization catalysts.

Abstract: The present disclosure is concerned with the discovery that hyaluronic acid, an agent well known to reduce the sequelae of trauma in mammalian joint tissue when applied directly to the traumatized tissue, will be carried to such traumatized tissue by the mammal's natural processes if applied at a site remote from the traumatized tissue. Thus, hyaluronic acid, in any therapeutically acceptable form, can be administered by the typical remote routes including intravenous, intramuscular, subcutaneous and topical. This makes the utilization of hyaluronic acid much more convenient and attractive. For instance the treatment of arthritis in horse or human joints with hyaluronic acid no longer requires more difficult intra articular injections.

Abstract: An endless printing band (1) consists preferably of rubber or synthetic rubber and in its production is cut from a hose-like blank by cuts extending along its edge. Said printing band (1) has in the one region of its outer side visually readable characters (3) and in an opposite region laterally inverted raised printable characters (5). In the region of the readable characters (3) on the inner side (11) of the printing band (1) inwardly projecting cams (6) are provided for the advance of the band while the inner side (7) of the region comprising the printable characters (5) is smooth. To nevertheless ensure at both band regions equal amounts of material for as uniform as possible shrinkage in the production of the printing band (1) in the region of the transport cams (6) on the outer side of the band (1) remote from the cams (6) recesses (9) are provided whose lowermost point (10) lies beneath the center of the band (1) between the cams (6) and preferably substantially at the height of the inner side (11) of said band region between the cams (6). As a result, at the run (2) of the band (1 ) having cams (6) and the likewise raised readable characters (3) so much material is saved that the material accumulation of the two band regions or runs (2 and 4) is substantially the same and this gives the same shrinkage in the production.

Abstract: PROBLEM TO BE SOLVED: To reduce a load applied to a computer by calculating convergent likelihood based on mouth shape information during a vocalizing section obtaining a candidate word from a photographing image of the mouth of a speaker. SOLUTION: A mouth shape recognition part 102 recognizes the shape and the movement of the mouth at a vocalizing time from a face image signal S101 (photographed image) read out from an image frame buffer 101. A word dictionary 104 stores syllable information and a phoneme model beforehand obtained related to the word candidate to be recognized. Further, a mouth shape syllable matching part 103 investigates a matching extent between the syllable information inputted from the word dictionary 104 and a syllable obtained from the operation of the mouth shape to output the result (mouth shape syllable matching score). Further, a word candidate convergent part 105 converges the word candidate according to the mouth shape syllable matching score.  Then, a voice recognition part 108 compares a line of a voice frame S108 of an inputted sound section with the phoneme model S111 of the word converged by the word candidate convergent part 105, and outputs the word with the highest likelihood as the recognition result.
