Title: Enzymatic process for the production of n-acetyl neuraminic acid
Inventor: KRAGL UDO
IPC: C12P19/26
Filed: 1990-11-14
Abstract: A process for obtaining N-acetylneuraminic acid from N-acetylglucosamine is disclosed, The process is carried out in a reactor which contains both N-acylglucosamine-2-epimerase (E.C. 5,1.3.8) which isomerizes GlcNAc into ManNAc, and N-acetyl-neuraminic acid pyruvate lyase (E.C. 4.1.3.3) which catalyzes the reaction of the resulting ManNAc with pyruvic acid to give Neu5Ac, GlcNAc and Pyr are fed into the reactor and Neu5Ac is obtained in the outglow. The process is preferably carried cut continuously and in particular in an enzyme membrane reactor at pH 7.5 and 25°C, especially using residence times of 0. 2 to 10 h, and with an excess of GlcNAc in comparison with Pyr which is subsequently added if necessary. Epimerase and lyase are preferably present in the reactor in a ratio of activities which is equivalent to the reciprocal value of the quotient of the conversion rates.

Abstract: An arrangement is disclosed for allocating a constrained common resource among a plurality of demands for the resource. The arrangement includesgenerating a set of patterns as candidates for a recommended solution, setting goals or constraints for a pattern to meet before the pattern becomes a candidate for the recommended solution, searching the set of patterns and determining those patterns that meet the goals, and appending those patterns that meet the goals to the recommended solution. A random distribution based on the demand for the resourceover a multi-dimension space can be generated. Responsive to the random distribution, a plurality of feasible patterns can be generated. Responsive to the feasible patterns, a multiplicity ratio may be generated. Responsive to a multiplicity ratio and to its corresponding feasible pattern, the plurality of feasible patterns may be reduced to a single feasible pattern, which can be included in the recommended solution. The generating and reducing can be repeated until the goals are met whereupon the resultant multiplicity ratios and feasible patterns can be provided as the recommended solution, and, responsive to the recommended solution, the common resource can be allocated among the plurality of demands.

Title: Gas sparged centrifugal separation and/or mixing
Inventor: TORREGROSSA LOUIS O
IPC: D21C11/00
Filed: 1991-06-25
Abstract: ABSTRACT      A number of different, efficient treatments of slurries and liquid with gas can be provided.  A slurry or liquid is introduced into a first end of a vortex.  A gas -- such as a chemically reactive gas -- is introduced from exteriorly of the vortex into contact with the slurry or liquid in the vortex, so that a desired reaction between the slurry or liquid and the gas takes place.  The treated slurry or liquid is removed from the second end of the vortex while any residual or carrier gas is removed from the first end of the vortex.  Gas introduction is preferably accomplished through a porous surface of revolution (e.g. cylindrical or conical) wall surrounding the vortex, the gas being in minute bubble form when it enters the slurry or liquid. This has particular applicability in the treatment of paper pulp using an ozone containing gas, or in reacting various liquids in the paper and pulp industry with gas (such as reaction of caustic solutions with chlorine or chlorine dioxide gas), the stripping of a strippable component from a liquid (e.g. stripping black liquor soap from black liquor, using air), or absorbing an absorbable component in a gas into a liquid (such as absorbing ozone, chlorine, or the like in water), or scrubbing furnace flue gases.  Gas may also optionally be removed from adjacent the second end of the vortex through a separate conduit from the gas being removed from the first end of the vortex.

IPC: H01L23/473
Filed: 1992-03-18
Abstract: ABSTRACT OF THE DISCLOSURE    A radiating device 10 has a rectangular parallelopiped block 11.  Block 11 includes a first group of holes 12 to 19 and a second group of holes 20 to 23 causing convection of air.  Passages for circulating gas and liquid serving as a heat pipe are formed to extend in X, Y and Z directions in block 11.  Opening ends of respective passages are closed by pins 51.  The air heated in the holes are radiated to the atmosphere from the top surface of the block through the second group of holes.          Accordingly, cool air in the atmosphere is absorbed in the holes of the first group, carries the heat generated from the inner wall surface of the holes, and radiated to the atmosphere from the top surface of the block.  Working fluid sealed in the passage frequently repeats evaporation and condensation.  The liquid condensed at the radiating portion returns to the heated portion along an inner wall surface defining the passage.

Abstract: Title DAMPER ASSEMBLY FOR SHIFT LEVER MECHANISM        Abstract of the Invention A compound shift lever mechanism employs a noise and vibration damper assembly for isolating an upper shift lever from a lower shift lever of a transmission.  In a preferred form, the levers are held in spaced,  coaxial alignment for unitary movement in a plurality of planes by a damper which comprises two parts.  The first part is a cylindrical elastomeric sleeve defining axially spaced female end portions comprising bores which frictionally overlie and snugly encase the two lever end portions which extend thereinto.  The second part is a cylindrical metallic shell which circumferentially  encapsulates  the  elastomeric  sleeve  which contains the respective ends of the upper and lower levers.  The shell thus radially encapsulates both of the end portions, as well as the sleeve, which incorporates a midportion containing a radial internal barrier to prevent direct physical contact between the extremities of the levers.   Finally, spaced female ends of the shell are crimped radially inwardly against the female end portions of the sleeve and, in turn, against both lever end portions, to frictionally retain the end portions in spaced, coaxial alignment.
