Title: Method of improving the acetylation of cellulose
Inventor: ZHUANG J MING
IPC: C08B1/02
Filed: 1993-02-09
Abstract: ABSTRACT          A novel method has been discovered for the pretreatment of cellulose with acetic acid and acetic anhydride under pressure, resulting in uniformly activated cellulose fibres. The improved process for producing cellulose diacetate comprises the steps of: (1) pretreating and activating the fluffed cellulose fibres in a solution of glacial acetic acid and acetic anhydride at room temperature and elevated pressure for a specific time; (2) mixing the activated cellulose containing acetic acid and anhydride further with a mixture of glacial acetic acid, acetic anhydride and sulphuric acid catalyst and acetylating the cellulose at specific initial and end temperatures to form primary cellulose acetate; and (3) partially neutralizing the sulphuric acid catalyst and destroying the excess acetic anhydride by adding an aqueous solution of magnesium acetate with dilute acetic acid to provide an excess of water in the reaction dope for hydrolysis at elevated temperature and pressure conditions.

Patent CA-2140842-A1 (CA)
Inventor: FEIGENBAUM MITCHELL
IPC: G06T3/00
Filed: 1991-03-25
Abstract: A method for automatically placing objects on a surface in proximity to corresponding predetermined locations without collision with such locations or other objects by defining a distance dependent attractive force between each object and the corresponding location which increases with increasing distance between the object and the location, and defining distance dependent repulsive force between each object and its neighboring objects and locations, such repulsive force decreasing with increasing distance. The initial position for each object is established in proximity with the corresponding location in accordance with predetermined criteria.      Thereafter the motion of the objects under the influence of such forces and of a frictional retarding force are determined by marginally stable incremental integration of such motion. The objects are statically placed at a predetermined target distance from the corresponding location at the position around the location at which the sum of the absolute values of the magnitudes of the forces acting on the object is at a minimum.
