Abstract: An exterior wall assembly water management system that provides the designer and building owner with the popular esthetics of synthetic stucco and the long-term reliability of water management. The water managed exterior system includes flashing, a weather-resistive barrier, a water durable board, a basecoat and an exterior finish. Either the water durable board, or an insulation layer secured to the water durable board, forms the exterior cladding of the building structure, and the basecoat and the exterior stucco finish are applied to the outer surface of the water durable board, or in the alternative to the insulation layer. The disclosed water managed exterior system efficiently directs any penetrating water to weeps, or the like, by providing a water drainage medium between the weather-resistive barrier and the water durable board. The unwanted water drains downwards via the drainage medium, is caught at the base of the wall by the flashing, and is further drained outside of the wall cladding.

Abstract: This invention is a new inspection technique using ultrasonic Lamb waves to measure reduction of pipe wall thickness due to localized corrosion at pipe supports.  The technique uses two transducers in a pitch-catch mode to send and receive a selected Lamb wave. The wave travels along the pipe wall in the circumferential direction. The reduction of the pipe wall thickness at the pipe support changes the time-of-flight between the two transducers. By comparing time-of-flight data measured from the pipe support area and from areas adjacent to the pipe support, one can quantify the change of time-of-flight due to the pipe corrosion wall loss at the support. A mathematical model, a sizing algorithm and a PC program have been developed to quantitatively relate in time-of-flight to the minimum remaining wall thickness. With them, one can quantify the minimum remaining pipe wall thickness at a pipe support by simply measuring the change in the time-of-flight.

Abstract: An apparatus for integer exception register (XER) renaming and methods of using the same are implemented. In a central processing unit (CPU) having a pipelined architecture, integer instructions that use or update the XER may be executed out-of-order using the XER renaming mechanism. Any instruction that updates the XER has an associated instruction identifier (IID) stored in a register. Subsequent instructions that use data in the XER use the stored IID to determine when the XER data has been updated by the execution of the instruction corresponding to the stored IID. As each instruction that updates XER data is executed, the data is stored in an XER rename buffer.  Instructions using XER data then obtain the updated, valid, XER data from the rename buffer. In this way, these instructions can obtain valid XER data prior to completion of the preceding instructions. The XER data is retrieved from the XER rename buffer by indexing into the buffer by using an index derived from the stored IID. Because the updated XER  data is available in the rename buffer before the updating instruction completes, out-of-order execution of instructions using or updating XER data is thereby realized.

Abstract: In a process for returning finely dispersed solids discharged from a reactor vessel (1) with a carrier gas through a discharge point (2) of the reactor vessel (1) to a return point (15) of the reactor vessel (1), the solids are separated in a solid separator (4), in particular a cyclone separator, then returned with a carrier gas to the reactor vessel (1) while a differential pressure is maintained between the solid separator (4) and the return point (15). Whe n the solids enter the reactor vessel (1), they are at least partially gasifie d and/or burned with oxygen supplied for that purpose. To enable the solids to be returned without moving parts which would be exposed to abrasion, in a continuous and controlled manner, the separated solids are directly and continuously aspirated by the solid separator (4) by means of a propellant g as and by an injector effect, accelerated and supplied to the reactor vessel (1 ).

Abstract: An escutcheon locking ring for an automatic sprinkler head having an externally threaded section with a top portion having an engaging member extending therefrom comprises a ring having a plurality of tabs extending from the inner perimeter, and an outer perimeter having a plurality of escutcheon engaging fingers depending therefrom. The escutcheon engaging fingers are curved and are formed with sharp ends. When positioned between the bottom surface of the engaging member and the escutcheon, the sharp ends of the depending escutcheon engaging fingers penetrate the surface of the escutcheon. An attempt to unscrew the escutcheon from the sprinkler head causes the rotation of the ring until frictional contact is made between the extending tabs and the engaging member. Once frictional contact is achieved, a positive lock is formed preventing one from unscrewing the escutcheon from the sprinkler head.  In an alternative embodiment, the extending tabs are replaced by extending U-shaped members. The curvature of the depending escutcheon fingers enables the locking ring of the present invention to be formed from a single sheet of material.

Abstract: A system and method for time division multiplexing multiple lower bandwidth signals into a high bandwidth signals such as a high-definition television signal. The invention provides an integrated transmission, distribution and routing signal format in which low-bandwidth signals are embedded in the active video and vertical blanking areas of a high-bandwidth signal. Data from the source data streams, including timing data, is formatted in packets, each packet comprising a plurality of channels. The packets are inserted into the high-bandwidth signal along with a header word providing a 'data valid bit' or 'status bit' for each of the channels, which identifies valid data words within the packet. The source data streams are accurately reconstituted by demultiplexing according to header data specifying routing destination, stream ID, stream type, channel usage and stream clock reclock reference for clock recovery at the receiving end.

Title: System for drilling and completing multilateral wells
Inventor: ALLEN DAVID WAYNE
IPC: E21B/
Filed: 1997-06-09
Granted: 2003-09-30
Abstract: The time required for establishing a multilateral well is reduced by enlarging a section of a wellbore and running a multilateral tool (7) which includes a preassembled combination of casing sections that form dual casing strings extending from the primary casing. The multilateral tool (7) incorporates a carrier section (2), a lateral section (8), and a main section (5). The tool is run with the lateral section (8) releasably held in coaxial alignment within the carrier section (2), and with the main section (5) fixed to the lower end of the carrier section (2). Once in place, the lateral section (8) is released and diverted out of a preformed window (4) in the lower end of the carrier section (2) and runs generally parallel to the main casing section (5). A lateral junction is thus formed at the carrier section window (4) in which dual casing strings are connected to the primary casing. A second window, preformed in the upper end of lateral section (8) is aligned with the bore of the primary casing when the lateral casing section is fully extended out of the carrier section window (4), thus permitting recovery of a diverting device incorporated in the carrier casing section (2) through the second window. The dual strings are then individually drilled and completed with pressure integrity between the dual strings maintained by using straddle equipment across the lateral junction.

Abstract: Disclosed are articles useful in cleansing, and particularly wet-like cleansing wipes, which are dry until used, where fluid is released from the article. These articles comprise: a) a carrier comprising a cellulosic fibro us structure having at least a first region of relatively high basis weight tha t comprises an essentially continuous network and a second region of a plurali ty of mutually discrete regions of relatively low basis weight which are circumscribed by the high basis weight first region; and b) an emulsion applied to the carrier, where the emulsion provides fluid for cleaning when shear forces are applied to the article. The first and second regions of the  cellulosic fibrous structure are disposed in a nonrandom, repeating pattern.  The articles offer a number of significant advantages over prior cleaning products when in the form of wet-like cleansing wipes such as those used for  cleaning of hard surfaces (e.g., floors, countertops, sinks, bathtubs, toilets, and the like). The inclusion of low basis weight regions avoids substantial fluid retention by the cellulosic fibrous substrate, which allow s fluid delivery to the surface being cleaned. The articles can be used in man y applications requiring the delivery of polar materials, in particular water and water-soluble or dispersible actives. These include toilet tissue, wipes  for personal cleansing, such as baby wipes, as well as those for the deliver y of water-soluble or dispersible antimicrobials or pharmaceutical actives.</S DOAB>

Title: Latching mechanism for mounting plate of pedestal closure assembly
Inventor: LESCHINGER MATTHEW
IPC: H02G9/10
Filed: 2000-08-22
Granted: 2005-12-27
Abstract: A latching mechanism for a pedestal closure assembly has a pair of substantially channel-shaped slots, each slot having two arms, a flanged base and first and second ends. Each flanged base has a cam-like edge and is connected to the second end of each respective slot. The cam-like edge interconnects the upper and lower surfaces of the second end. A pair of legs adapted to be received by each slot are also included in the claimed latching mechanism. Each leg has a limiting edge and includes an end portion adapted to limit the motion of the legs when they are received in the respective slots. At least one flexible latch arm adapted to engage the flanged base of at least one of the slots is connected to one of the legs. Each latch arm includes a finger element beyond the end portion of the limiting edge of the leg. The finger element includes an engagement portion which abuts the lower surface of the flanged base of the leg when the leg is received in its respective slot. The finger element has a cam-follower surface which bears against the cam-like edge of the slot which flexes the latch arm allowing the engagement portion to move beyond the cam-like edge of the flanged base of the slot so that the latch arm engages the flanged base. Thus, the slot is configured and dimensioned to slidingly receive each leg. The latching mechanism and the pedestal closure assembly can be constructed of non-metallic material. Each leg of the latching mechanism can contain a spacer bead and a transverse flange, each flexible latch arm can include an integral lip, and each slot can contain a guide rail. All of these are included to keep the legs more firmly secured in the slots when the latching mechanism is engaged. Additionally, the pedestal closure assembly can have a service wire passageway with a channel slot which allows the internal equipment to be worked on without having to interrupt service and without having to unearth the lower housing section.

Abstract: In accordance with the invention, a postal security device (PSD) (10) contai ns a non-volatile memory (13) which does not depend on battery power such as an EEPROM (13), and contains a nonvolatile memory (14, 16) which does depend on battery power, such as a static RAM. The PSD (10) also contains an encryption engine (12, 14, 22). An encryption key is developed and is stored in the static RAM (14), which is sized to be only large enough to contain the encryption key. A larg e body of data, too large to fit in the static RAM, is encrypted by means of the encryption engine (12, 14, 22) and with reference to the encryption key, and is stored in the EEPROM (13). This body of data typically includes cryptographic keys and sensitive bit-images. When th e PSD is powered, a large RAM (typically a dynamic RAM) (16) is available to receive the large body of data, decrypted using the encryption key. A tamper switch (17) cuts power to both RAMs (14, 16) in the event of tampering.

Abstract: L'invention concerne un séparateur de particules inertiel intégré, sous forme d'une admission radiale bifurquée, pour moteur à turbine à gaz. Les moteurs à admission radiale comprennent un conduit d'admission incurvé, aspirant de l'air radialement à partir d'une gaine de distribution extérieure et réacheminant le courant d'air axialement dans le conduit annulaire d'un compresseur. En modifiant le conduit d'admission radiale de façon qu'il comprenne un conduit de dérivation, on obtient, de façon économique, un séparateur de particules inertiel intégré à l'intérieur du moteur, ce qui permet d'éliminer, dans le courant d'air d'admission, les particules de sable, les flocons de glace et autres particules endommageant le moteur. L'admission radiale s'écarte des systèmes conventionnels, par le fait qu'elle comprend une surface avant concave discontinue s'étendant entre un bord avant de l'entrée et la paroi intérieure du conduit du compresseur. La surface avant concave oblige le courant d'air à suivre une trajectoire incurvée, ce qui permet de séparer des particules relativement lourdes du courant d'air, sous l'effet de la force centrifuge. La discontinuité dans la surface avant concave d'admission radiale comprend un conduit de dérivation, en aval de l'entrée et un séparateur de flux, en forme de cuspide, en aval du conduit de dérivation, en vue de détourner un courant d'air de dérivation dans le conduit de dérivation.
