    摘要: A sterile product containing a substance embedded in a carrier is produced by use of a supercritical gas. In one embodiment, a mixture is formed of a substance, carrier and supercritical gas such as nitrous oxide or carbon dioxide, and the supercritical gas is separated from the substance and carrier to obtain the product. In another embodiment, the supercritical gas contains the substance, and is mixed with an atomized organic solvent containing the carrier to form a mixture. The supercritical gas extracts the solvent, and is separated from the substance and carrier to produce the product. Alternatively, the carrier can be in the supercritical gas and the substance in the solvent, or both the substance and carrier can be in the solvent. Atomization and formation of the mixture can be carried out by feeding the supercritical gas and solvent through a nozzle into a spray tower or column. The supercritical gas containing the solvent is separated to obtain the product in the form of a dry powder containing spheres of the carrier having the substance embedded therein. The carrier can be polymers, lipids, lecithins or waxes, and the substance can be medicines, toxins, viruses, diagnostic materials, herbicides, insecticides or pesticides. An apparatus for carrying out the method contains a spray tower and other means for performing the method steps.

    摘要: An electrochemical storage cell or battery based on alkali metal and sulfur with at least one anode chamber containing alkali metal and one cathode chamber containing sulfur-alkali compounds separated from each other by an ion-conducting solid electrolyte wherein the sulfur-alkali compounds are at least partially dissolved in an organic liquid solvent with a boiling point above the operating temperature of the cell, the operating temperature being in the range of about 100.degree. to 200 C. The solvent permits lower operating temperature with reduced rate of corrosion.

    摘要: 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.

    摘要: The invention is represented by a transdermal medicated patch for the extended release of 17.beta.-estradiol to the skin. The transdermal patch is formed by an outer covering, a matrix containing from 1% to 5% (w/w) 17.beta.-estradiol, and a protective liner which is removed before use. The matrix is formed of pressure-sensitive adhesive acrylic copolymers, in which the active ingredient is dissolved or dispersed. The acrylic copolymers are obtained by radical copolymerization of 2-ethylhexyl acrylate, methyl acrylate, acrylic acid, vinyl acetate, hydroxyethyl acrylate or a mixture thereof. Optionally quantities of less than 0.5% (w/w) of other substances may be added.
