  • Patent number: 6723372
    Abstract: A process for the production of encased, spherical granular grains comprising spraying grains which consist of a prostane derivative and a cyclodextrin vehicle, forming together a prostane-cyclodextrine-clathrate, with an aqueous polymer dispersion of ethyl cellulose and/or poly(methyl)acrylic acid ester in a fluidized or boiling bed is disclosed. The polymer dispersion is applied in a thickness equivalent to 1-5% (w/w) of the total mass of the encased grains. The coated grains are cured for at least 24 hours. Grains produced according to this method have a pharmaceutical active ingredient release profile which remains unchanged over the storage time.

  • Publication number: 20030138487
    Abstract: An apparatus and method for locking a gun. The apparatus includes a dummy round configured for insertion into a firing chamber of a gun, a locking component configured for coupling with the dummy round, and an elongated sleeve rotatably coupled with the locking component. The locking component includes a keyed head positioned within a longitudinal channel of the elongated sleeve. The locking component and elongated sleeve are insertable through the discharge end of a gun's barrel. An actuating mechanism, such as a key is insertable through the channel of the elongated sleeve to engage with the keyed head and rotate the locking mechanism relative to the elongated sleeve. Rotation of the locking mechanism effects a friction lock between the locking mechanism and the dummy round.
