摘要:
An improved self-priming, centrifugal pump arrangement for mixed-media flow includes a volute housing having a suction and a discharge, a volute scroll disposed within the volute housing, an impeller disposed within the volute scroll, a suction hopper and a discharge hopper within volute housing, a back cover and a wear plate attached to the volute housing. By optimizing the geometry of these internal components, noise is reduced, efficiency of the pump is improved, and the self-priming feature is maintained.

An apparatus for estimating an ambient environment at which inorganic scale will form in a downhole fluid includes a stress chamber disposed in a borehole in a production zone at a location within a specified range of maximum pressure and configured to receive a sample of the fluid from the production zone and to apply an ambient condition to the sample that causes the formation of inorganic scale. An inorganic scale sensor is configured to sense formation of inorganic scale within the chamber and an ambient environment sensor is configured to sense an ambient environment within the chamber at which the formation of inorganic scale occurs. The apparatus further includes a processor configured to receive measurement data from the inorganic scale sensor and the ambient environment sensor and to identify the ambient environment at which the formation of inorganic scale occurs.
摘要:
A package includes four outer walls and an internal wall running between two of the outer walls. The four outer walls and the internal wall define first and second cells. First and second pivot members are disposed in the first and second cells. A first pair of hinge members connects the first pivot member to two of the walls defining the first cell and a second pair of hinge members connects the second pivot member to two of the walls defining the second cell.

Disclosed are treatment agents and methods of treatment utilizing the agents directed toward diseases in which the disease causing pathogen includes α6β1 integrin receptors and/or α6β4 integrin receptors on the surface of the pathogen. In one embodiment, the disease can be breast cancer. The therapeutic agents disclosed include a polypeptide comprising at least a portion of the G domain of the laminin-5 α3 chain that has been shown to bind α6β1 integrin receptors and α6β4 integrin receptors. In one embodiment, the therapeutic agents can be fused or chimeric materials in which the laminin-5 α3 chain polypeptide has been chemically bound to another material that can be useful in the destruction or neutralization of the pathogen.
摘要:
The present invention provides systems and methods for end squaring and/or dividing elongated materials by determining an actual orientation of the elongated material, or an actual position of an associated pair of positioning mechanisms that are contactable with the elongated material, and changing the actual orientation to correspond with a desired orientation through independent movement of the positioning mechanisms prior to or during the end squaring and/or dividing operation.
摘要:
An exemplary multi-axis television navigation system defines television navigation axes according to attributes of television programs. In one implementation, if a television program has an attribute defining an axis, then the exemplary system links a predefined database query associated with the axis to metadata for the television program. When launched, the predefined query returns a sequence of navigable television programs having the attribute that defines the axis.
摘要:
A vehicle wheel is disclosed that is made up of a plurality of extrusions. A rim may be provided in either a cylindrical form or in the form of a series of arcuate segments. Rim attachment brackets are provided to secure spokes to the rim. Spokes are provided between the rim and a hub that defines an axle aperture. The rim is roll formed to form tire retention beads and the outer surface of the rim that's in the abstract.
摘要:
An adjustable barrier for use with a building having a door frame with a door frame opening, a track assembly, and a garage door positioned between the track assembly to selectively cover the door frame opening, the adjustable barrier comprising a barrier bracket and an extendable barrier panel. The adjustable barrier is adapted to seal off a garage door gap located between the garage door and the door frame, and is positioned between the door frame and the track to create a barrier preventing a pest from bypassing the garage door and entering the building through the garage door gap. The extendable barrier panel selectively extends and retracts to adjust to the distance between the track and the door frame, and may further be tapered to allow the adjustable barrier to maintain contact with the track when the track curves away from the door frame.
