  • Center of roll for tapes and their spools or rollrack hubs
    Publication number: 20030122029
    Abstract: The device “CENTERS FOR TAPE ROLLS AND THEIR SPOOLS OR ROLLRACK HUBS” has been put forward. This innovation consists of a new shape in the structure of the center of the rolls in a way which is very similar to a triangle which will be called “Delta” and for a second preferred embodiment of the invention which is very similar to a square which will be called “Tetrahedral” and which working with a spool of an adequate shape called “For Delta Rolls” or “For Tetrahedral Rolls” as a second preferred embodiment of the invention, the sliding of the roll on the spool will be hindered and therefore avoid the problems of inconsistency in the tension of the tape in packing machines.

  • Apparatus for recovering acetic acid from aqueous streams
    Patent number: 5492603
    Abstract: Disclosed is a method and apparatus for recovering acetic acid from an acetic acid/water waste stream which includes a dehydration column into which the stream is fed and a liquid-liquid extraction system for recovering acetic acid from the condensate of the overhead stream of the dehydration column. Optionally, low pressure and/or high pressure absorber systems are provided to process vapor and/or liquid streams associated with the recovery system and/or the plant in which the acetic acid is used to further the recovery of acetic acid and reduce atmospheric pollution.
    Type: Grant
    Filed: March 15, 1994
    Date of Patent: February 20, 1996
    Assignee: Glitsch, Inc.
