Granted: 2010-06-29
Abstract: Excellent transporters which enable a drug to efficaciously exist in vivo over a long time are designed and thus a drug delivery system is constructed by using these transporters. The transporters are prepared by forming a covalent bond by reacting polyalkylene glycol or its reactive derivative with a phospholipid and a drug. When systemically or topically administered, these transporters are retained at a target site in vivo, thereby making it possible to achieve a sustained drug effect over a long time by a single administration.

Title: Process to prepare 1,4-dihydropyridine intermediates and derivatives thereof
Inventor: CHE DAQING
IPC: C07D211/90
Filed: 2003-04-14
Granted: 2007-09-18
Abstract: An improved catalyst is disclosed for a process involving the preparation of benzylidene intermediates useful in the preparation of 1,4-dihydropyridine compounds and derivatives thereof useful as medicines such as for example felodipine. This is accomplished by the condensation of an aldehyde and an acetoacetate in the presence of a novel catalyst system that includes a pyridyl carboxylic acid and a secondary amine. It has been found that through the use of the present invention the purity and yield of the desired isomer of the benzylidene intermediate can be maximized, thus avoiding the requirement of additional purification steps. The use of these intermediates can then be further reacted to form the required dihydropyridines, again having a very high purity and yield compared with the prior art.

Abstract: Appareil pour raccorder les conduits primaires et secondaires afin d'acheminer un fluide sous pression. Il comprend une première face fixée autour d'une extrémité ouverte du premier conduit, et une face en poche fixée autour d'une extrémité ouverte du second conduit, formant ainsi une poche. La première face est fixée à la face en poche de manière à ce que la première face soit essentiellement perpendiculaire aux parois de la poche, et adjacente à une extrémité ouverte de ladite poche. Un joint étanche est engagé par coulissement dans la poche et définit un passage par la partie centrale de ladite poche. Le joint étanche comporte une surface de joint adjacente et essentiellement parallèle à la première face, et une face de pression du côté opposé dans la poche. Un élément en biais exerce une force diagonale sur le joint étanche vers la première face, et un joint de poche scelle une périphérie extérieure du joint par rapport aux parois de la poche. Un joint d'étanchéité principal est placé entre la face du joint étanche et la première face, et la face de pression du joint étanche est exposée au fluide acheminé par les conduits et a une surface qui est plus grande que celle de la surface du joint étanche entre le joint d'étanchéité principal et le passage qui traverse le joint étanche. Plus la pression à l'intérieur des conduits est élevée, plus grande est la force exercée sur le joint d'étanchéité principal, ce qui scelle le raccord.

Filed: 2003-11-14
Granted: 2007-05-22
Abstract: A non-locking detector switch, provided on or near an adapter with an antenna for accessing a memory unit, is switched on and off by a connector plug when that plug, containing a memory function unit, is coupled to the adapter with such an antenna.  Accordingly, the connection status of each connector can be directly and simultaneously detected by the switching operation of the detector switch just before the antenna detects the closing of the memory function unit to opposed to the antenna.  This enables the exact and immediate detection of the entire coupling statuses of each of a number of adapters as opposed to just the incomplete coupling status of any one single-adapter.

Abstract: Apparatus and methods for measuring cross sectional area and flaws in a continuous sucker rod string (20) as the string is conveyed within a borehole (32). These measured parameters are useful in monitoring the physical integrity of the sucker rod string. A magnet (44) is used to saturate an increment (48) of continuous sucker rod, and a coil (45) is used to measure induced flux. Cross sectional area of the rod increment is computed from the flux measurement. One or more Hall effect transducers (42) are used to measure leakage from the increment as a function of distance along the increment. This measurement is used to detect and quantify the type of flaw within the rod increment being investigated. The process is repeated as the sucker rod string is conveyed into or out of the borehole.

Abstract: Rapid arc extinguishing devices for air break switches have a whip with at least an end portion of nonmetallic material such as fiber reinforced plastic with a conductive path on its surface. The nonmetallic material is a single tapered rod or an assembly of a plurality of rods successively inserted into an outer rod. The conductive path on the whip is of various individual and combination forms of which some include a metal braid, foil, sheath or wound wire. Particular forms of the conductive path on the rod have enhanced durability and arc resistance at the areas of the whip most likely to be subject to arcing with a latch of the device upon switch opening or closing. Further forms of the whip are a combination in which an end portion as described is attached to an all metal base portion that is arranged to include a portion of the whip subject to arcing on switch closing. Another form of device has a latch engaging a whip at a rotating wheel on the latch. Whips with conductors having metal strands are made with strands bonded to the nonmetallic rod surface for greater durability in use. Whips with an all metal base portion have a metal spine within its nonmetallic portion through the joint region between the two portions, to minimize risk of damage to the nonmetallic portion from high stress in that region when such a whip is released from a latch. Also, a latch with a wheel or roller is improved by a design that limits wear of the conductive path on a nonmetallic rod surface.

Abstract: A ballast resonant inverter with a self-oscillating driver IC powers and dims a gas discharge lamp. A feedback circuit automatically adjusts IC oscillator frequency for safe and stable inverter operation above the resonant frequency following changes in the resonant load. The feedback signal is derived from resonant inverter output voltage, by attenuating, programmed phase shifting and injecting the resulting signal in a timing circuit of the IC. The feedback circuit includes an active inverter circuit or passive RC phase boosting networks coupled in series. Phase control of the feedback signal by variable RC networks is used in transient modes of ballast-lamp operations.

Abstract: Functional yet decorative luminaires intended to create distinctive environments within specific areas of a space in which one or more luminaires are used, the luminaires of the invention visually tie to architectural elements of the space by providing a customizable glow of color surrounding a typically white light that acts to illuminate the space functionally. A downlighting luminaire configured according to the invention as one example is typically configured to utilize two separate reflectors, usually reflectors having concave reflective surfaces and being mounted concentrically within a housing, an inner reflector directing light centrally through an aperture of the luminaire with the light so directed typically being white light useful for illumination intended to facilitate usual activities within the space. An outer reflector is spaced from the inner reflector with a transparent or translucent disc, such as an acrylic plastic disc, being held between the reflectors, the disc having a colored film adhered preferably to lower surfaces thereof to cause portions of the light emanating from lamping disposed above the disc to be colored by passage through the colored film, the disc being readily removable and replaced with a disc having a different color adhered thereto so that a particular luminaire can he customized as to color selection depending on user choice at any given time. An annulus of glowing, colored light exits the periphery of the luminaire aperture outwardly of the inner cone, the reflective surfaces of the outer reflector directing at least portions of the colored light passing through the disc and colored film through an annular aperture of the luminaire, thereby creating a distinctive appearance of a central, white shaft of light emanating from the inner reflector and a glowing annulus of colored light surrounding the white shaft of light. Peripheral edges of the inner reflector can be positioned fleshly with the luminaire aperture or can extend to one or more positions outwardly of the luminaire aperture and thus "proud" of a ceiling or the like within which the luminaire is recessed, surface-mounted or pendently mounted inter alia.
