Title: Biodegradable implant precursor
Inventor: POLSON ALAN M
IPC: A61K31/74
Filed: 1994-07-07
Abstract: The invention is directed to a biodegradable implant precursor having a two-part structure made of an outer sac and a liquid content.  The implant precursor is composed of a biodegradable, water-coagulable thermoplastic polymer and a water-miscible organic solvent.  When administered to an implant site in an animal, the implant precursor will solidify in situ to a solid, microporous matrix by dissipation of the organic solvent to surrounding tissue fluids and coagulation of the polymer.  The invention also includes methods of making the implant precursor, an apparatus for forming the precursor, and a kit containing the apparatus.  Also provided are methods of using the implant precursor for treating a tissue defect in an animal, for example, for enhancing cell growth and tissue regeneration, wound and organ repair, nerve regeneration, soft and hard tissue regeneration, and the like, for delivery of biologically-active substances to tissue or organs, and other like therapies.
Patent CA-2121939-A1 (CA)
Inventor: CLAVENNA LEROY R
IPC: C01B3/40
Filed: 1994-04-22
Abstract: A particulate, precalcined low silica content zirconia, especially one stabilized with yttria, is useful as a catalyst support or as a heat transfer solids component for conducting chemical reactions at high temperature, in oxidizing, reducing or hydrothermal conditions, especially in syn gas operations. An admixture of precalcined particulate low silica content zirconia, particularly a low silica content yttria-stabilized zirconia, is employed in a preferred embodiment as a heat transfer solid, in concentrations ranging generally from about 10 wt% to about 99.9 wt%, with a particulate catalyst, notably a nickel-on-alumina catalyst, in concentration ranging generally from about 0.1 wt% to about 90 wt%. Such an admixture provides a particularly useful catalytic contact mass in high temperature oxidizing, reducing and hydrothermal environments, notably in conducting synthesis gas generation operations. This type of bed promotes continuous, highly efficient heat and mass transfer within the reacting gas phase. The presence of the heat transfer solid as a bed component maintains excellent bed fluidization characteristics, suppressing the normal tendency of the catalyst to sinter or agglomerate; tendencies which promote defluidization of the bed. Moreover, the heat transfer particles of the bed are highly attrition resistant, and are chemically compatible with the catalyst particles of the admixture.

IPC: C07B57/00
Filed: 1992-12-15
Abstract: An improved process for the separation of enantiomers of a mixture of certain aliphatic carboxylic acids or esters thereof is disclosed. The process involves adding in inert liquid to the reaction solution formed by: (i) forming a salt solution comprising said racemic mixture of a C1 to C6 linear or branched aliphatic carboxylic acid and an organic or inorganic base; (ii) treating said salt solution with less than equimolar equivalents of a chiral organic nitrogenous base; (iii) precipitating from the reaction solution formed in step (ii) the less soluble diastereomeric salt; (iv) addition of a countersolvent to the slurry formed in step (iii); (v) extracting the more soluble diastereomeric salt or the salt of carboxylic acid and the base added in step (i) into the countersolvent. The inert liquid and the countersolvent must be of sufficiently different density. The inert liquid is substantially immiscible with the countersolvent and does not dissolve appreciable quantities of the precipitated less soluble diastereomeric salt.

Title: Picture compression apparatus, picture reproducing apparatus and picture drawing apparatus
Inventor: SUZUOKI MASAKAZU
IPC: H04N19/426
Filed: 1994-09-13
Abstract: Digital image data are compressed in a first iteration of orthogonally transforming a predetermined amount of the original image data, such as index data for a splite pattern, and quantizing the transform coefficients. Then the quantized data are locally decoded, and the decoded data are compared with the original image data. If there are no errors, that is, the decoded data matches the original image data, the quantized data are variable length encoded to form compressed data for output, such as recording on a CD-ROM recording medium. If there are errors, then a next iteration is performed, in which the original image data are bit shifted and then orthogonally transformed, the transform coefficients are quantized, and the quantized data are locally decoded. As before, the decoded data are compared with the original image data. If there are no errors, the quantized data are variable length encoded to form compressed data for output. If there are errors, then the original image data are further bit shifted in a next iteration, and the above described processing is repeated until there are no errors. The recorded compressed data are reproduced, variable length decoded, dequantized, inverse orthogonally transformed, inverse bit shifted, and used as picture data for display on a television.
Patent CA-2133268-A1 (CA)
Title: Membrane-based process for the recovery of lactic acid by fermentation of carbohydrate substrates containing fermentable sugars
Inventor: RUSSO LAWRENCE J JR
IPC: B01D61/58
Filed: 1994-09-29
Abstract: MEMBRANE-BASED PROCESS FOR THE RECOVERY OF LACTIC ACID       BY FERMENTATION OF CARBOHYDRATE SUBSTRATES          CONTAINING FERMENTABLE SUGARS                 ABSTRACT OF THE DISCLSOURE A substantially continuous membrane separation process has been discovered in which the known benefits of a cell-recycle fermentor are unexpectedly enhanced because pH is controlled from 4.0 to 5.5 with a nitrogen-containing base, most preferably ammonium hydroxide. The ammonium lactate formed is not precipitated. This allows continuous removal of lactic acid so as to maintain a concentration of lactic acid about 12%, preferably about 6% by wt in the broth, optionally supplemented with thin stillage or steep water, and optionally buffered with protease. When combined with recycle of UF retentate, operating this cell-recycle fermentor allows the build-up of a cell population in the range from above 5 x 109 CFU/ml to 5 x 1010 CFU/ml, which population is much denser than one which can be produced with the specified pH control in a batch fermentor, after self-termination of the fermentation. This super-dense population of cells, in turn, not only accelerates produc-tion of lactic acid but also minimizes contamination by foreign cells; and since the UF retentate is recycled, a relatively large portion of the broth in the fermentor may be withdrawn as a fermentor effluent stream, sufficient to produce a specified high fluid velocity when the effluent stream is flowed over UF membranes used in the UF modules. The high fluid velocity, preferably from 5-10 m/sec, at. relatively flow pressure less than 1140 kPa (150 psig), produces a scrubbing action over the membrane surfaces which are therefore not fouled over long periods of operation. In a batch fermentation with pH control, when the fermentation is self-terminated the total lactic acid present is about 10% by wt (measured by HPLC), though free always < 4%, and the live cell population is lower than 5 x 109 CFU/ml because many cells die as pH drops.

IPC: B65H18/26
Filed: 1995-01-31
Abstract: There is provided a coiling machine for coiling a continuous paper web having two large rolls that form a coil bed for uptake of a paper coil. The space bounded by the large rolls and the coil is formed as a pressure-tight chamber that has a compressed air connection.      Particularly for the present invention, one of the two large rolls has a jacket that is essentially more intensely deformable than the jacket of the other roll and, thus, one large roll is softer than the other large roll. The upper vertex of the softer large roll is located lower than the upper vertex of the harder large roll. The web guidance is configured for one embodiment of the coiling machine such that the web is introduced from below, and between the two large rolls, to wind around the softer large roll. For another embodiment of the coiling machine, the web is introduced through a pressing gap between one of the large rolls and the coil.
