  • Patent number: 6948636
    Abstract: A device for dispensing liquid from a bag has upper and lower casing halves and a closure holding together the casing halves. A pressure piston in the casing can press the bag against the lower casing half. This piston is operated by a rocking lever having an upper end bearing on the upper casing half and a lower end on which the piston is pivoted and a tension spring and flexible element connected between the casing halves and the upper end of the rocking lever and angularly biasing the lever for movement from a generally horizontal position with the piston raised and a tilted position with the piston lowered for applying such a force to the pressure piston that a pressure is generated in the bag that causes the discharge of a constant liquid volume per unit of time.

  • Patent number: 6902741
    Abstract: The transdermal system includes a sex hormone-containing adhesive matrix, which contains inclusions of a sex hormone in a hydrophilic non-crosslinked polymer in dissolved or dispersed form. The inclusions have a concentration of 20 to 90 percent by weight of the sex hormone, which is more than 50 percent by weight amorphous. The hydrophilic non-crosslinked polymer can be polyvinylpyrrolidone, methylcellulose, ethylcellulose or hydroxyethylcellulose. The adhesive matrix can be a polyisobutylene, ethylene-vinyl-acetate copolymer or a polystyrene-butadiene block copolymer.
