Title: Opioid agonist/antagonist combinations
Inventor: COLUCCI ROBERT D
IPC: A61K9/22
Filed: 1998-12-22
Granted: 2005-09-13
Abstract: The invention is directed in part to oral dosage forms comprising a combination of an orally analgesically effective amount of an opioid agonist and an orally active opioid antagonist, the opioid antagonist being included in a ratio to the opioid agonist to provide a combination product which is analgesically effective when the combination is administered orally, but which is aversive in a physically dependent subject. Preferably, the amount of opioid antagonist included in t he combination product provides at least a mildly negative "aversive" experience in physically dependent addicts (e.g., precipitated abstinence syndrome).

Abstract: A process for recovering one of alumina hydrate, magnesium hydroxide and magnesium aluminate spinel (MgAl2O4) from aluminum dross wherein the dross is processed to a non-metallic product (NMP). The dross may contain fluxing salts which are removed in providing the NMP. The NMP may be derived from aluminum dross which does not contain fluxing salts sometimes referred to as white dross. The process comprises digesting the non-metallic product with an acid selected from the group consisting of sulfuric, hydrochloric, hydrofluoric and phosphoric acid or mixtures thereof to provide a slurry containing dissolved alumina, magnesia and a solid component, for example, containing magnesium aluminate spinel. Instead of an acid, a base such as sodium hydroxide may be used. The slurry is filtered to separate the solid component from the liquid containing dissolved constituents such as alumina and magnesia to recover the solid component.

Abstract: A process is disclosed for the in-situ conversion and recovery of heavy crude oils and natural bitumens from subsurface formations (27) using either a continuous operating with one or more injection and production boreholes (21) and (201), which may included horizontal boreholes (212), or a cyclic operation whereby both injection and production occurs in the same boreholes (21).  A mixture of reducing gases, oxidizing gases, and steam are fed to the downhole combustion device (206) located in the injection boreholes (21). Combustion of the reducing gas-oxidizing gas mixture is carried out to produce superheated steam and hot reducing gases for injection into the formation to convert and upgrade the heavy crude of bitumen into lighter hydrocarbons. Communication between boreholes (21) and (201) is induced by fracturing. Injection wells may be cyclically operated where wellhead pressure is reduced and hydrocarbons in the vicinity of the boreholes (21) are produced, or continuously injected to drive hydrocarbons to the production boreholes (201) for recovery.  In both operations, the hydrocarbons produced are collected at the surface for further processing.

Abstract: A DS-CDMA transmission method capable of improving the accuracy of channel estimation using pilot symbols by eliminating cross-correlation between pilot symbols inserted into code channels in CDMA multiplexing carrying out fast signal transmission. In each frame assembler, the pilot symbols, which are used for channel estimation for coherent detection, are inserted into coded information data on code channels at fixed intervals, and then the data is modulated by the modulator. The modulated data symbols in each code channel from the modulator are spread by the spreading modulator, the pilot symbols are spread using a spreading code, whereas the information symbols are spread using different spreading codes assigned to respective code channels. The spread signals of the code channels are summed up by the adder to be transmitted.
