  • Patent number: 4006515
    Abstract: Apparatus and procedures for continuously forming rosette shaped tampons from aggregate containing tubular sacks or overwraps having withdrawal strings at one end and assembling the tampons in inserters, the apparatus comprising rotary transfer mechanism for engaging the withdrawal strings of the sacks and sequentially delivering them to a rotary assembly turret having a multiplicity of assembling stations mounted around its periphery. Each inserter comprises inner and outer parts, and feeding means are provided to individually feed and position an inner inserter and an outer inserter in holders at each assembly station. Each station has a reciprocating string engaging rod which acts to remove a sack by its string from the transfer mechanism and positions the sack to be drawn upwardly by vacuum into an overlying annular inversion chamber wherein the sack is inverted into rosette shape by the action of a pressure-vacuum reciprocating inversion rod.

  • Patent number: 4007134
    Abstract: A rigid composite body containing crystalline molecular sieves and having liquid-permeable channels extending in a substantially vertical direction from one surface of said body to the interior thereof, preferably to an opposite surface, is charged with carbon dioxide so that when brought in contact with water or an aqueous beverage, the carbon dioxide will be released from the molecular sieve composite body to carbonate the solution. Such rigid, composite bodies are secured in a sealable, nestable, stackable container which provides a convenient and efficient means for dispensing such composite bodies in combination with a dry instant beverage mix for the preparation of carbonated beverages upon the addition of water.
