Title: Method of ophthalmic drug delivery
Inventor: MACKEEN DONALD LEWIS
IPC: A61K33/06
Filed: 1993-12-07
Granted: 1999-04-27
Abstract: A method for prolonged delivery of a therapeutic agent to the eye is disclosed. The method provides for the addition of a desired drug to a suitable, preferably non-aqueous carrier. An amount of the carrier con taining the therapeutic dose of the drug is placed on the skin exterior to the ocular surface near the lateral and lower lid margins. Move ments of the orbicularis oculi associated with the scissor-like closing of the lids of the eye continuously transport small portions of the ther apeutic agent and carrier into the interpalpebral space where the drug is released to the corneal surface. Further provided is a calcium-based ophthalmic composition which is particularly effective treating dry eye syndrome and which is optimally delivered by the method just de scribed.

Title: Method and apparatus for the removal of hydrogen sulfide from a process gas stream
Inventor: HUESTIS ALLAN CHARLES
IPC: C21B13/02
Filed: 1994-08-16
Granted: 1999-11-02
Abstract: An improved method and apparatus for forming metallized iron by direct reduction of particulate iron oxide is disclosed.   Spent reducing gas  is recycled from the reduction furnace through a cooler-scrubber  and  a  catalyst-containing stoichiometric  gas reformer.  Upon removing the process gas from the cooler-scrubber, it is contacted with a chlorine dioxide spray, then compressed and cooled, the sulfur compound removed, and the process gas recycled either into the furnace cooling zone, or directly into the reformer, or divided and directed into both uses.  Thus, most of the sulfur containing components of the spent reducing gas are removed, thereby reducing the sulfur contamination of the gas reformer catalyst. Reducing sulfur contamination of the gas reformer catalyst improves the overall efficiency of the direct reduction process.  Either high sulfur ores, or high sulfur process gas, or both can be utilized in the invented process.

Abstract: A system for recovery of relations in a data base in case of errors, comprises functionnality executed by a computer and ensuring that data in the data base are structured as items of data in a number of recovery sub-systems, each item of data belonging to only one sub-system.      If a sub-system contains one or more items of data that depend on one or more items of data in another sub-system, the first mentioned sub-system is marked as depending on a third sub-system. If a first sub-system is marked as depending on said second sub-system which is marked as depending on a third sub-system, said first sub-system is recursively marked as depending on said third sub-system.      Furthermore no two subsystems are marked as depending on each other. Integrity constraints between an item of data in one sub-system and an item of data in another sub-system is admitted provided that one of these sub-systems is marked as depending on the other one. Recovery actions are performed on a sub-system so as to only result in changing items of data of that sub-system and of sub-systems marked as depending on it.

Abstract: Dans un système de communication numérique (1), on connaît des procédés de récupération de phase pour les signaux modulés par déplacement de phase en quadrature. On a proposé d'étendre l'application de ces procédés aux signaux de modulation d'amplitude en quadrature (QAM) multirésolution, qui peuvent être représentés par des constellations de signaux invariantes en rotation. A cette fin, on détermine, avec chaque symbole reçu (r¿i?), une référence de phase (ø¿i?) pour une constellation de bits de haute priorité (bits HP), et on construit, en rapport avec cette référence de phase (ø¿i?), une sous-constellation (Clx) pour des bits de faible priorité (bits LP), cette sous-constellation (Clx) étant invariante en rotation. La sous-configuration (Clx) subit une translation en direction d'une origine (O) de la constellation de signaux, puis les bits de faible priorité (bits LP) sont déterminés par détermination, en rapport avec la sous-constellation ayant subi la rotation et la translation, d'une valeur minimale du carré de la distance euclidienne (Ed) du symbole reçu (b¿i?') ayant subi la rotation et la translation. Ainsi, on obtient une procédé simple de détection pour une constellation de signaux QAM 2R(2,2). On peut rendre le procédé adaptatif et même récursif dans le cas des constellations de signaux plus complexes telles qu'une constellation de signaux QAM 64.

Abstract: An anti-vibration collar having a wear resistant, vibration absorbing sleeve which mounts over the conventional releasable connection between an extension shaft and a drive wrench. The collar substantially reduces run-out which is typical to conventional relatively loose mating connections and which are prone to excessive vibration and losses in torque. Consequently, the collar substantially increases torque imparted to a fastener and significantly decreases vibration experienced by an operator, thereby improving the quality of the driven fasteners and decreasing the chance of operator injury.
