  • Patent number: 6468563
    Abstract: A process for producing rapidly disintegrating pharmaceutical formulations containing an extract is provided. The process comprises providing a dry powdered extract and a lubricant, compacting the powdered extract with the lubricant, using between about 0.5-10% lubricant by weight. The compacting is done using a device that yields flakes. The flakes are then crushed into granules, and the granules are compressed with conventional excipients such as bulking agents, glidants, disintegrants, flow regulators and other additives into pharmaceutical formulations.

  • Patent number: 6454836
    Abstract: A downhole preferential hydrocarbon gas recovery system and method employ preferentially selective materials to separate the hydrocarbon gas from contaminants. According to one aspect of the invention, the preferentially selective materials are arranged in tubes with the hydrocarbon gas flowing through the tubes and the contaminants permeating out through the preferentially selective material.

  • Patent number: 4801455
    Abstract: A pharmaceutical formulation for the parenteral, in particular intravenous, administration of sparingly soluble substances is obtained when the very finely ground substance, with a maximum particle diameter of 3 .mu.m, is dispersed in an oil phase which contains emulsifier, and this mixture is emulsified with water for injection, is rendered isotonic and is homogenized using a high-pressure homogenizer, so that the resultant product is a solid/liquid/liquid disperse system.

  • Patent number: 4727109
    Abstract: A pharmaceutical preparation having an active substance of low solubility in water and gastric juices that has an initially liquid carrier system consisting of a hydrophilic component, a hydrophobic component and a solubilizer. The solvent mixture contains 9 to 90 parts by weight of solubilizer and 90 to 5 parts by weight of a hydropholic component, such as polyethylene glykol, 1,2-propylene glykol, 1,3-butanediol, 1,4-butanediol, 1,2-propanediol, glycerol, mannitol, sorbitol or polyoxyethylene polyoxypropylene copolymerisate or mixtures of such substances, and 40 to 1 parts by weight of an oleophilic component, such as natural and/or semisynthetic vegetable or animal oils or synthetic oils, such as neutral oil or waxes. The active substance is dissolved in the carrier system or dispersed in a stable way and for an oral application, is filled into drug capsules made of gelatine.

  • Patent number: 4721603
    Abstract: A specific baffle arrangement within a catalytic reactor improves separation of gaseous hydrocarbon reaction products from catalyst within the reactor vessel of a fluidized catalytic cracker unit. The catalytic reactor vessel includes an outer generally cylindrical shell having a stripping zone arranged at the lower end of the vessel. An inlet riser conduit forming a primary reaction zone extends generally within the shell from the lower end of the vessel to a location near the top of the vessel. A shroud surrounds the upper end of the riser conduit and forms an annular outlet for downwardly discharging a mixtrue of hydrocarbon and catalyst. An annular catalyst disengaging riser baffle for deflecting the mixture from the outlet toward the wall of the vessel is arranged on the outside of the riser conduit below the annular outlet and above the stripping zone.

  • Patent number: 4605794
    Abstract: A modified sorbitol with improved tableting properties, viz, has a melting point of about 96.degree. C., a bulk density of 0.3-0.6 g/ml, a .gamma.-sorbitol content of at least 90%, a purity of at least 98%, a specific surface area of 0.7-1.5 m.sup.2 /g, a bending strength of at least 7 N/mm.sup.2 at a compressive force of at least 10,000 N, and a friability of less than 1% at a compressive force of at least 10,000 N, can be prepared by obtaining a sorbitol solution by hydrogenation of crystallized glucose at a temperature below 170.degree. C., and spray-drying this solution at a temperature of 140.degree. to 170.degree. C. The sorbitol thus obtained has a water content of less than 1%.The sorbitol is useful for the production of compressed formulations.
