Abstract: L'invention concerne des méthodes améliorées pour introduire des mutations dirigées dans des molécules d'ADN circulaires considérées en utilisant des paires d'amorces mutagènes. Les paires d'armorces mutagènes sont choisies pour être entièrement ou partiellement complémentaires, le ou les sites de mutation étant situés dans la région de complémentarité. La paire d'amorces mutagènes est hybridée avec les brins opposés d'une molécule d'ADN circulaire contenant la séquence d'ADN à modifier par mutagenèse. Après l'hybridation, les premier et second brins d'ADN ayant subi une mutagenèse, comprenant chacun un élément de la paire d'amorces oligonucléotidiques mutagènes sont synthétisés par une réaction d'amplification cyclique linéaire. Après avoir terminé l'étape de synthèse consistant en une amplification cyclique linéaire, le mélange réactionnel est traité avec une enzyme de sélection qui digère les brins matriciels parentaux. Après l'étape de digestion, on forme un ADN intermédiaire circulaire à deux brins. Les intermédiaires d'ADN circulaire à deux brins sont utilisés pour transformer des cellules hôtes appropriées compétentes. On peut, d'une manière avantageuse, récupérer des cellules transformées, l'ADN circulaire fermé à deux brins correspondant aux molécules matricielles parentales, mais contenant la ou les mutations recherchées. L'invention concerne également des nécessaires pour réaliser une mutagenèse dirigée selon la méthode décrite.

Title: High definition television for simultaneously displaying plural images contained in broadcasting signals of mutually different broadcasting systems
Inventor: LEE TAE-SUNG
IPC: H04N5/45
Filed: 1998-06-22
Granted: 2001-10-30
Abstract: A high definition television (HDTV) for displaying an image contained in a broadcasting signal of a mutually different broadcasting system is provided. The HDTV restores a first image signal being an image signal contained in a HD digital broadcasting signal and a second image signal being an image signal contained in a NTSC analog broadcasting signal which are input from an antenna and an external input port, and format-converts each restored image signal into an image signal having a predetermined frame format. An image signal synthesizer including two memories and a timing signal generator time-base-compresses the format-converted first and second image signals so as to correspond to a main picture and a sub-picture of a PIP image to be displayed, and synthesizes the first and second image signals into a single PIP image signal. A CRT displays a PIP image contained in the PIP image signal on a screen.

Abstract: A nozzle arrangement for a flue gas scrubbing column for use in desulfurizations, in which the scrubbing column has a sump, a baffle-free zone above the sump and a nozzle arrangement above the absorption zone.  The nozzle arrangement includes a branch pipe system for supply of a scrubbing liquid, and nozzles connected each by an intermediate pipe section to the branch pipe system.  The position and length of the intermediate sections is selected by:        (a) flow density profiles are formed in predetermined cross sectional planes of the scrubbing column by the spray cones of the nozzles;        (b) in each of these cross sectional planes, the flow density profiles of different spray cones are superimposed on one another;        (c) the flow density profiles of different cross sectional planes are superimposed upon projection thereof onto one of said planes to form a flow density complete profile in said one plane over the entire cross section of the scrubbing column;        (d) the flow density complete profile is compared with a predetermined value; and (e) upon deviation of the flow density complete profile from said predetermined value, the position of at least one of said nozzles is adjusted by varying at least one of the position and length of the associated intermediate pipe section; and (f) repeating steps (a) through (e) until the flow density complete profile for the cross section of the scrubbing column has an approximately constant value up to a wall region of said cross section.  The system of the invention optimizes the scrubbing of the gas and largely eliminates regions wherein the gas stream can pass through the scrubber without having been subjected to the scrubbing liquid in an effective scrubbing step. The result is improved absorption efficiency.

Title: Bypass diverter box for drilling mud separation unit
Inventor: WILLIAMS J TERRELL
IPC: B07B13/16
Filed: 1998-09-29
Granted: 2006-01-03
Abstract: A bypass diverter box disposed upstream from conventional solids control equipment of a mud system of a drilling rig contains a drilling mud separation unit having a continuous-loop scalper screen that is driven in a continuous loop to separate, convey and discharge large amounts of gumbo, heavy clays and drill solids at the end of the separation unit. The flow divider box is a box-like housing with a verter plate, upper and lower baffle plates and a grate that allows drilling fluid or drilling mud to be selectively directed to the mud separation unit to be separated prior to passing to the conventional downstream solids control equipment or allows the fluid to bypass the separation unit and flow directly to the conventional solids control equipment. The bypass diverter box baffle plates, diverter plate and grate, and selective utilization of the mud separation unit removes large amounts of gumbo, heavy clays and drill solids from the drilling mud and allows high flow rates to be easily processed by shale shakers and other conventional downstream solids control equipment of the mud system and compliments the drilling operations with respect to changes in the lithology, geological formations, or loss of returns in relation to the gallons pumped or folume of drilling fluid or drilling mud entering the bypass diverter box.

Abstract: L'invention concerne la biorestauration thermochimique et la décontamination de sédiments et de sols contaminés par des contaminants organiques, ainsi que par des matériaux inorganiques, et leur réutilisation bénéfique ultérieure. On obtient de nouveaux produits sans danger pour l'environnement quand on mélange certains additifs, tels que du calcium ou des oxydes de métaux, avec les matériaux contaminés. Le procédé de biorestauration consiste à réchauffer le mélange à 1150  DEG C  SIMILAR  1500  DEG C afin d'obtenir un produit réactionnel en fusion, tout en insufflant au moins une partie d'un excédent de mélange d'oxygène ou de l'air à travers le mélange dans le but d'entretenir le mélange et d'atteindre un niveau élevé de destruction par la chaleur et d'élimination des contaminants organiques. On refroidit ensuite rapidement le mélange dans de l'air humide, de la vapeur ou de l'eau afin d'éviter la transformation du matériau amorphe en cristaux. On incorpore les contaminants organiques, tels que le chrome, le nickel ou le zinc, et on les immobilise totalement à l'intérieur du réseau de silicate amorphe. Les émissions dans l'atmosphère provoquées par ce procédé ne sont pas toxiques et peuvent répondre aux normes d'hygiène et d'environnement. On peut pulvériser le matériau amorphe afin de produire une poudre possédant les propriétés du ciment, soit par réaction avec une solution alcaline, soit par mélange avec d'autres matériaux, ce qui permet d'obtenir des ciments mélangés. Les résistances à la compression des bétons fabriqués à partir de cette poudre et des ses mélanges, sont comparables ou supérieures à celles des normes ASTM pour des mises en application polyvalentes du béton. Cette poudre, ces ciments mélangés et les bétons ou mortiers qui en découlent peuvent également réussir le test de lixiviation EPA TCLP, ce qui les rend utilisables pour l'environnement.

Abstract: A radiometer calibrating system (150) utilizes an adjustable noise source (100) for calibrating a radiometer. The noise source includes a transistor configured as a noise equivalent circuit having a gate port, drain port and source port. A source inductance providing series feedback for the noise source has one end coupled to the source port of the noise equivalent circuit and another end connected to the ground. A bias circuit controls the amount of DC bias applied to the noise equivalent circuit. In order to match the impedances in the noise source, an output impedance matching network is connected to the gate port of the noise equivalent circuit. The output and input impedance networks have an output port and input port, respectively. Included in the noise source is a port switch that terminates a matched load to the output port when a cold thermal radiation temperature is generated at the input port, and alternatively, the port switch terminates the matched load to the input port when the warm thermal radiation temperature is generated at the output port.

Abstract: This invention is a flexible post (401) for endodontic or reconstructive tooth therapy having a modulus of elasticity which is less than or equal to that of dentin of 18 GPa. The present invention is preferably made of medical grade optical glass fibers (402) or fiberglass fibers. The micro-filaments of the present invention are treated to impart flexibility to each fiber. The fibers are twisted by twisting on other non-axial arrangements of the fibers to impart strength to the unit post. This allows it to function as a permanent post in a tooth. The dental post is flexible and the post conforms to the natural curved contours of a root canal to reduce machining of the tooth and mechanical weakening of the tooth structure.

Abstract: An actively controlled rotary steerable drilling system for directional drilling of wells having a tool collar rotated by a drill string during well drilling. A bit shaft has an upper portion within the tool collar and a lower end extending from the collar and supporting a drill bit. The bit shaft is omni-directionally pivotally supported intermediate its upper and lower ends by a universal joint within the collar and is rotatably driven by the collar. To achieve controlled steering of the rotating drill bit, orientation of the bit shaft relative to the tool collar is sensed and the bit shaft is maintained geostationary and selectively axially inclined relative to the tool collar during drill string rotation by rotating it about the universal joint by means of an offsetting mandrel that is rotated counter to collar rotation and at the same frequency of rotation. A drilling fluid driven turbine in combination with an alternator produces electric power which is used to drive an electric motor. The electric motor provides rotation to the offsetting mandrel with respect to the tool collar and is servo-controlled by signal input from position sensing elements such as magnetometers, gyroscopic sensors, and accelerometers which provide real time position signals to the motor control. In addition, when necessary, a brake is used to maintain the off-setting mandrel and the bit shaft axis geostationary, the brake being servo-controlled by signal input from position sensing elements which provide real time position signals to the brake control. Alternatively, a turbine is connected to the offsetting mandrel to provide rotation to the offsetting mandrel with respect to the tool collar and a brake is used to servo-control the turbine by signal input from position sensors which provide real time position signals to the brake control.

Abstract: A tissue sample is conventionally visual-ized in a microscope. A selectively activated convex surface is provided, preferably at the distal end of a rod. This selectively activated convex surface when activated, typically with a laser through an optic light path in the microscope, provides the activated region with adhe-sive properties. At least one portion of the tis-sue sample which is to be extracted is identified.  This identified portion is contacted with a por-tion of the selectively activated convex surface on the end of the rod. When the convex surface is activated, typically by exposure to laser light in the footprint of the desired sample, an adhe-sive transfer surface on the selectively activated convex surface is provided which adheres to the desired cells in the footprint of the desired sam-ple. Thereafter, the adhesive transfer surface is separated from the remainder of the tissue sam-ple while maintaining adhesion with the desired cells.

Abstract: This invention is an ophthalmic surgery system, and method for treating presbyopia by performing ablative photodecomposition of the corneal surface (200). The offset image of a variable aperture, such as a variable width slit, and variable diameter iris diaphragm, is scanned in a preselected pattern to perform ablative sculpting of predetermined portions of a corneal surface. The scanning is performed to ablate an optical zone sized to match the patient pupil with a peripheral transition zone (216) outside the pupil. The shape of the ablated optical zone is different from the shape of the final optical correction on the anterior surface of the cornea. The optical zone (211) corrects for near vision centrally, and far vision peripherally. A movable image displacement mechanism enables radial displacement, and angular rotation of the profiled beam exiting from the variable aperture. The invention enables wide area treatment with a laser having a narrower beam than the treatment area, and can be used in the treatment of many conditions in conjunction with presbyopia such as hyperopia, hyperopic astigmatism and irregular refractive aberrations.

Abstract: A flexible container (10) is provided for the storage, and administration of medical solutions. The container incorporates a transparent front sheet (12) made from a planar layer of a polymer, and an opposing rear sheet (14). The rear sheet is made from a planar laminate layer. The front, and rear sheets are sealed together along a common peripheral edge (16) to form a volume enclosure (17). The volume enclosure is constructed of materials having high oxygen, and moisture barrier properties which allows the container thermoplastic to be stored for extended periods of time without degrading the contents. The volume enclosure is then inflated with a pressurized gas to permanently stretch the front, and the rear sheets outwardly, and to thereby increase the volume capacity of the container. An alternative embodiment of the container incorporates multiple compartments (22, 23, 24) separated by peeled seals (25, 26) for containing a diluent, and a medicament. The seals are ruptured by manipulations of the container to thereby mix the contents together for delivery through standard IV an-arrangement to a patient.
