The present invention relates to an oral drug delivery system with biphasic release characteristics comprising a porous matrix comprising at least one drug substance, sugar(s), a release retarding polymer, gas generating components and optionally, pharma-ceuti-cally acceptable auxiliary components wherein the pharmaceutical composition further comprises a coating of said drug substance. The pharmaceutical composi-tion, either in the form of pellets (multiparticulate or single unit dosage form), beads, granules, capsules or tablets, is retained in the stomach while selectively delivering the drug(s) at gastrointestinal levels and upper parts of the small intestine over an extended period of time. The release of the drug from the said pharmaceutical composition is characterized by a biphasic release profile of the drug substance, which exhibits both immediate and controlled release characteristics.

A pharmaceutical composition in the form of tablets or capsules provides a combination of temporal and spatial control of drug delivery to a patient for effective therapeutic results. The pharmaceutical composition comprises a drug, a gas generating component, a swelling agent, a viscolyzing agent, and optionally a gel forming polymer. The swelling agent belongs to a class of compounds known as superdisintegrants (e.g., cross-linked polyvinylpyrrolidone or sodium carboxymethylcellulose). The viscolyzing agent initially and the gel forming polymer thereafter form a hydrated gel matrix which entraps the gas, causing the tablet or capsule to be retained in the stomach or upper part of the small intestine (spatial control). At the same time, the hydrated gel matrix creates a tortuous diffusion path for the drug resulting in sustained release of the drug (temporal control). A preferred once daily ciprofloxacin formulation comprises 69.9% profloxacin base, 0.34% sodium alginate, 1.103% xanthan gum, 13.7% sodium bicarbonate, 12.1% cross-linked polyvinylpyrrolidone, and optionally other pharmaceutical xcipients, the formulation being in the form of a coated or uncoated tablet or capsule.

A fire extinguishing device of the explosive type is disclosed for use against conflagrations, wherein the force of detonation of the device is minimized through the use of low density/low mass components; no part of the device having sufficient mass or density to constitute a ballistic hazard, nor be hazardous in concussive shock due to the explosive burst. The present invention is composed of a lightweight casing (3) of frangible material, with a protective exterior sheathing (7). Within the internal cavity of the device, a pyrotechnic detonator (5) is located at or near the center of mass, and is actuated by fuse cord(s) (6) extending from the detonator, the end(s) of which extend(s) from the interior detonator to mounting on the exterior surface. The device is chargeable with a variety of fire-retardant chemical agents (8), including dry powders, two-part reactants, liquid components or others, singly or in combination.

A diffusely reflective optical film includes a blended layer extending from a first to a second zone of the film. The blended layer includes first and second polymer materials separated into distinct first and second phases, respectively. The blended layer may have the same composition and thickness in the first and second zones, but different first and second diffusely reflective characteristics in the first and second zones, respectively. The difference between the first and second diffusely reflective characteristics may not be attributable to any difference in composition or thickness of the layer between the first and second zones. Instead, the difference between the first and second diffusely reflective characteristic may be attributable to a difference in birefringence of the first and/or second polymer materials between the first and second zones. The blend morphology of the blended layer may be substantially the same in the first and second zones.

A method for drying traditional Chinese medicine materials in mixing mode through microwave vacuum and hot air comprises placing the traditional Chinese medicine materials in a microwave vacuum drying stove, drying the traditional Chinese medicine materials for 3 to 5 minutes under the condition that the vacuum ranges from 0.07Mpa to 0.09Mpa and the unit microwave power ranges from 3W to 5W, delivering the traditional Chinese medicine materials into a hot air dryer, drying the traditional Chinese medicine materials for 1 to 3 hours under the temperature ranging from 70 DEG C to 90 DEG C, and finally delivering the traditional Chinese medicine materials to the microwave vacuum drying stove again for drying under the condition of the first step till the end.
