Title: Retrofitting existing concrete columns by external prestressing
Inventor: SAATCIOGLU MURAT
IPC: E04C3/34
Filed: 1999-03-23
Granted: 2007-01-23
Abstract: A large number of existing reinforced concrete structures, such as buildings and bridges, if subjected to abnormal loads, such as those expected during earthquakes or bomb blast, may experience significant inelasticity in their critical regions. It is economically not feasible to replace the entire existing infrastructure with new and improved structures; retrofitting provides the only solution to the problem of seismically and otherwise structurally deficient existing structures. A new retrofitting process has been developed to improve strength and deformability of existing reinforced concrete columns (10). The process involves determining column (10) critical regions, identifying critical stresses that may lead to brittle shear and/or compression failures, determining external prestressing to overcome some of these stresses and to provide lateral confining pressure to improve the ductility of compression concrete. External prestressing is provided by placing prestressing hoops (14) around the column (10) at predetermined locations. Each hoop (14) includes a strand (16) that encircles the column (10) with its ends fixed under tension to an anchor (1S). The invention is applicable to concrete columns (10) of any geometric cross section. For circular columns prestressing may be applied directly on the surface of the column (11) by the strands (16). For columns (10) with rectilinear geometry such as square, rectangular and other polygonal cross-sectional shapes, additional hardware (76, 77, 85, 86) is necessary between the strand (16) and the flat surfaces (74) to distribute the prestressing force as evenly as possible on the surfaces (74) of the column (10). External protection of hardware against corrosion, fire and vandalism may be carried out by means of fiber reinforced or plain concrete jackets, shotcreeting or similar sprayed applications of cement based materials (62), and different types of paints.

Abstract: In a sensor arrangement for sensing temperature and strain, an optical fiber with a Bragg grating therein is arranged on a substrate and embedded in a cover layer. The fiber is initially adhered onto an adhesive carrier, which then positions and ap-plies the fiber onto the substrate. The fiber is point-wise fixed onto the substrate by a binder applied through holes in the adhesive carrier. Next, the carrier is stripped off to leave the fiber on the substrate. A cover layer is applied over the fiber and the substrate. Temperature and strain variations are trans-mitted from the cover layer into the fiber as non-circularly-symmetrical strains. The strain and temperature can be independ-ently determined using this single sensor, by feeding quasi-depolarized light into the fiber and measuring the overlapping birefringent reflections from the Bragg grating. The full width at half maximum value indicates the temperature, while the Bragg wavelengths indicate the strain and the temperature.

Title: Wire cable for window regulators of automobiles
Inventor: KIM YOUNG-JO
IPC: D07B1/16
Filed: 2001-05-24
Granted: 2004-10-26
Abstract: A wire cable for window regulators of automobiles is disclosed. In the wire cable, the core strand has a double-layer twisted strand structure with an F+6+12 element wire structure, and consists of a high-strength synthetic resin filament used as a core element wire (F), six internal element wires primarily twisted around the core element wire to form an internal layer around the core element wire, and twelve external element wires secondarily twisted around the internal layer to form an external layer around the internal layer.      Eight external strands, having a single-layer twisted strand structure with a 1+6 element wire structure, are twisted around the core strand to form an 8×7+(F+6+12) element wire structure of the wire cable in cooperation with the core strand. The synthetic resin filament used as the core element wire of the core strand has a diameter slightly larger than that of the internal and external element wires of the core strand. The core strand is also compressed at a compression ratio of 2 - 10%, thus bringing its element wires into surface contact with each other in place of point contact. In this wire cable, the element wires of the core strand are not likely to be deformed or broken, thus being improved in its fatigue resistance against a repeated bending action, in addition to improving the productivity of the wire cables.

Abstract: A Coriolis mass flow sensor includes a flow tube, a light source positioned adjacent a first side of the flow tube and a light detector positioned adjacent a second side of the flow tube. A drive device is operatively situated relative to the flow tube for vibrating the flow tube, such that the flow tube moves through a path defined between the light source and the light detector. In other aspects of the invention, a Coriolis mass flow sensor includes a flow tube and a frame having the flow tube mounted thereon. A drive device is operatively situated relative to the frame for vibrating the frame and at least one pick off sensor is situated relative to the flow tube so as to measure the twist in the flow tube due to Coriolis force. Other aspects of the invention concern a straight- tube Coriolis mass flow sensor. A flexible flow tube defines a generally linear flow path. A drive device is positioned to actuate the flow tube, and first and second pick off sensors are positioned at the first and second ends of the flow tube, respectively. The first and second pick off sensors output a signal in response to movement of the flow tube, wherein a Coriolis force established by a flow of material through the flow tube causes a phase shift between the signals output by the first and second pick off sensors.

Granted: 2008-10-28
Abstract: A Wireless Code Division Multiple Access method and apparatus for determining the transmitted rate of a voice/data signal from a mobile station to a Base Station. Variable rate vocoders transmit voice at one of several predetermined frame rates. The receiver determines the transmitted rate based on one of several frame parameters. One of the parameters is received frame energy.  The received frame energy is measured over the length of the relevant portion of the frame. Energy is measured over the half of the frame that can only contain energy if a full rate frame is sent. If the energy measured exceeds a threshold, then full rate is indicated.  Else, energy is measured over the fourth of a frame that can only contain energy if a half rate frame is sent. If the energy exceeds a threshold, then half rate is indicated. The procedure is repeated for quarter and eighth rates.

Title: Intelligent valve positioner tuning
Inventor: HANSEN PETER DANIEL
IPC: G05B13/04
Filed: 2000-09-06
Granted: 2008-05-20
Abstract: A valve position controller tuning method avoids impact of friction in valve positioner tuning by building a dynamic model of a valve positioner from a monotonic open-loop response of a valve stem position to a change in valve position controller output. To this end, a model form is selected based on the type of pneumatic actuator and relay that controls valve flow modulating of member motion, and the valve position controller is operated in an open-lop mode. The method includes changing a valve position controller output signal to cause the valve positioner to move a valve flow modulating member, connected to valve positioner, monotonically from one stuck position to another stuck position immediately after a motion in that same direction. When a valve stem position reaches a position threshold, a first valve stem position change and a corresponding time change are measured. The method includes measuring valve stem position changes at times that depend on the first measured time change. Using the measured results, valve positioner response parameters are calculated for the selected model form from which valve position controller tuning constants are calculated.</ SDOAB>
