Title: Modular pouch making machine
Inventor: HARTMAN DONN A
IPC: B65B9/10
Filed: 1995-02-14
Abstract: A rotary continuous pouch machine has a modular construction for increased flexibility and versatility.  The machine has a base unit module which unwinds a continuous web of pouch material, folds it and forms a plurality of vertical seals to define a series of pouches having an open top.  A product feed module supplies product to a filling module which fills the pouches through the open top.  A top sealer on the base unit module closes the filled pouches and a knife module severs the web into individual pouches.  Each module can have its own, individually-controlled servo motor for driving the moving parts of the module and for providing feedback signals of speed and position to a main control module.  The control module governs the servo motors so as to maintain registry and tension of the web at each module.  The modules are interchangeably connected to one another so that each module can be exchanged for another of the same type but of different size or other characteristic without requiring replacement of the other modules.

Title: Process for producing d-chiro-inositol
Inventor: SATO KIYOSHI
IPC: C07C35/16
Filed: 1994-08-08
Abstract: An aqueous solution of kasugamycin or its salt is either mixed with a strongly acidic ion-exchange resin of the H+-form in a reaction vessel, or is brought into contact with a strongly acidic ion-exchange resin of the H+-form in a column containing said resin, followed by heating said aqueous solution and the resin under an atmospheric pressure or an elevated pressure, thereby to effect hydrolytic reaction of kasugamycin. By this reaction, an acidic reaction solution containing D-chiro-inositol is produced. This acidic reaction solution containing D-chiro-inositol is separated from said strongly acidic ion-exchange resin. Subsequently, D-chiro-inositol is recovered from said reaction solution. For this recovery, said acidic reaction solution is passed successively through a column of a strongly acidic ion-exchange resin of the H+-form and through a column of a strongly basic ion exchange resin of the OH--form, so that a neutral aqueous eluate containing D-chiro-inositol is obtained. This neutral aqueous eluate is then concentrated and crystals of D-chiro-inositol are made to deposit, whereby D-chiro-inositol of a high purity can be harvested with high efficiency.
