Abstract:

A computer-based system for taking the physical inventory of beverages dispensed in full and partially full containers so as to effectively control the theft and overpouring. The products to be inventoried, such as liquor bottles are identified by conventional barcodes that can be scanned by a scanner that is operably interconnected with a hand-held computer. The step of scanning the barcodes produces, on the touch-sensitive screen of the hand-held computer, product information concerning the product contained within the scanned bottle including a silhouette of the bottle. In accomplishing the inventory, the user indicates by touching on the silhouette of the bottle the fluid level within the bottle. This information is inputted in the computer data storage and is used to calculate the volume of beverage remaining in the bottle.

Abstract:

A process is disclosed for preparation of purified terephthalic acid containing 200 ppmw or less of p-toluic acid. A filter cake of purified terephthalic acid is prepared by filtering, under a differential pressure of about or greater than 0. 5 psi over the system pressure and a temperature within the range of from about 100. degree. C. to about 205. degree. C. , an aqueous slurry of purified terephthalic acid containing a solution of p-toluic acid. The aqueous solution of p-toluic acid remaining in the filter cake of purified terephthalic acid is displaced from the filter cake by water under a pressure gradient over the system pressure at a temperature within the range of from about 100. degree. C. to about 205. degree. C. Pressure flash evaporation of water remaining in the filter cake occurs upon release of the system pressure to lower pressure with consequent lower temperature.
