摘要:
The present invention provides a process for the preparation 6-[3-(hetero)aryloxy-2-fluoro-benzyl]-2H-pyridazin-3-one compounds 1 where R2 is an optionally substituted aryl or an optionally substituted heteroaryl, R6 is NO2, NH2, alkyl, halogen, or a function group readily derived therefrom and R4c is hydrogen or alkyl. There also is provided a process for the preparation of phenylacetic acid compounds 2, wherein R2 and R6 are as defined previously and R5a is hydrogen or alkyl, which are useful for the preparation of pyridazinone compounds.
摘要:
Methods and systems of estimating usage of components within an application environment can use statistical, rather than deterministic methods that may be too intrusive or disturb a network used by the application environment. Different transaction types may have estimated usage of components within the application environment and its corresponding confidence level (that the transaction type uses that specific component) calculated and presented to a user. Asynchronous data and data routinely generated by a component may be used. The workload and utilization data may be conditioned before determining the estimated usage to smooth and filter data and determine accuracy of the correlations.

A weighted scrub brush has a brush head defining a leading end, a trailing end, a pair of laterally opposing ends, a downwardly facing bristle support surface, and an upwardly opening weight recess. A weight having first and second opposing ends is removably positioned within the weight recess. Mating support members support the first end of the weight, while a cantilevered support latch partially overlaps the second end of the weight to secure the weight within the weight recess. A conduit extends from a liquid intake port, through the handle, and to the brush head to dispense liquid from the conduit to the plurality of bristles. A roller is secured to a central body portion of the brush head forward of the handle, such that the brush head may be pivoted to a forward, inverted position to roll the brush.

Methods and systems of managing a network can be used in which physical components may be provisioned or de-provisioned without having to manually reconfigure a logical instrument. Logical instruments may be used to monitor or control an application environment. The logical instruments may be coupled to logical objects, which in turn are coupled to physical model objects, which in turn correspond to physical components. Host agents may reside on the physical components to actuate or have actuated a physical component. From a perspective of an operator or a program optimizing or otherwise managing an application environment on a network, the logical instruments appear as static variables (values can change, but the variable itself does not) where dynamic changes to physical components may occur but are transparent to the operator or program.

A printhead assembly includes a carrier having a fluid manifold defined therein such that the fluid manifold includes a first chamber and a second chamber; a plurality of printhead dies each mounted on the carrier and communicating with at least one of the first chamber and the second chamber of the fluid manifold; a fluid delivery assembly coupled with the carrier and including a first chamber and a second chamber; and a fluid interconnect fluidically coupling the first chamber of the fluid manifold with the first chamber of the fluid delivery assembly and the second chamber of the fluid manifold with the second chamber of the fluid delivery assembly.

A multi-pass heat exchanger including first and second plates forming a fluid chamber therebetween having an inlet opening and an outlet opening, and a turbulizer plate having rows of fluid flow augmenting convolutions in the fluid chamber, the turbulizer plate including at least one barrier dividing the fluid chamber into first and second pass regions such that fluid flowing in the fluid chamber flows around an end of the barrier when flowing from the first pass region to the second pass regions, the turbulizer plate having portions defining a notch area therebetween for fluid to pass through when flowing in the fluid chamber around the end of the barrier from the first pass region to the second pass region.
摘要:
A heat exchanger useful for high temperature applications such as EGR cooling and fuel reformer applications comprises a tube bundle made up of a plurality of tubes, each having at least one end expanded to an enlarged polygonal cross-section, and having central portions with a generally smaller cross section. When the tubes are formed into a bundle, the enlarged end portions nest with one another and interstitial spaces are provided between the central portions of the tube. The enlarged end portions are preferably retained by a header ring having a multifaceted inner peripheral sidewall which is adapted to form brazed lap joints with the outward facing surfaces of the peripheral tubes end portions in the tube bundle. In one preferred arrangement, axially aligned enlarged portions are provided intermediate the ends of at least some of the tubes. These enlarged intermediate portions nest with one another and eliminate or reduce the need for baffle plates.

There is provided a container with an opening formed by cutting a panel from the container body. A pull feature is joined to the panel and the panel is reattached to the container to cover the opening. The panel is reattached with a sealed, frangible interface so that pulling the pull feature of the panel removes the panel from the container to provide access to the contents within the container through the opening. The pull feature may be a pull tab joined to an outer surface of the panel or may be a pull tab and a ring. To facilitate the formation of the sealed, frangible interface, the ring may be positioned between an outer edge of the panel and an inner edge of the container or may be positioned to overhang the outer edge of the panel and to contact the container proximate the opening. The container may also include a second opening at an opposite end of the container that includes a closure sealed to the container.
摘要:
A reversible liferaft having two canopies (4a, 4b), one on each side, and an inflatable column (13), which supports the upper canopy (4a) when the liferaft is floating on water. The column (13) preferably has a narrow center (12) and wider extremities (3a, 3b) and is positioned in an aperture (7) in the floor (2) on the liferaft. A sleeve (9) is connected at one end (10) of the edge of the aperture (7) and at the other end (11) to the center (12) of the column (13).
