A ball valve seat assembly includes a seat ring for mounting in a ball valve seat pocket and an annular face seal mounts on one end of the seat ring. The resilient annular face seal member is mounted in a groove in the seat member with one end portion exposed to seal against a ball valve member. The annular seal member has an enlarged end portion located in the closed end of the annular groove. An inner wall portion of the seat ring is permanently deformed radially outwardly over the enlarged po...

This invention involves the method and apparatus for simultaneously placing a coating of a selected material on the outer surface of an extended cylindrical object such as a pipe or conduit, and holding the coating in position by wrapping the coating with a strip of thin film formed to a cylindrical contour and sealed with a longitudinal seam. This is accomplished in one mode by inserting the pipe through a tubular concentric mandrel, wrapping and sealing the plastic film against the mandrel and...

A chimeric, non-human animal can be produced by a method that entails providing a microcell that contains one or more foreign chromosomes or fragment(s) thereof and then fusing the microcell with a pluripotent cell, thereby introducing the foreign chromosome(s) or fragment(s) into the latter. The pluripotent cell thus obtained can be used to generate a chimeric, non-human animal, the cells, tissues, and/or progeny of which can be the source of a product, such as an antibody, that is associated w...

Disclosed is a head structure for accomplishing a wireless structure of a video cassette recorder and for improving its assembling work. The head has a body for supporting a head portion for recording, erasing and/or reproducing data on a tape. A pair of neck portions are separately formed on a lower portion of the body for being necked in a through hole of a base in the video cassette recorder. A pair of head terminals are protrudingly and downwardly formed on a lower surface of the body, betwe...

A method of producing a pollutant adsorption and degradation article, and such article, are provided. At least one adsorbent is mixed with at least one pollutant transforming agent to form a mixture. This mixture is compacted to form a porous, highly permeable article. If necessary, the article can be modified with surfactant either after the compacting step or by adding the surfactant to the mixture prior to the compacting step. In addition, if necessary, a binding agent can be added to the mix...

There is disclosed novel mutant IGFBP-3 polypeptides and fragments thereof that have either no binding, or diminished binding to IGFs, yet retain their ability to bind to the human IGFBP-3 receptor ("P4.33"). The present invention provides novel mutant IGFBP-3 nucleic acid sequences, and expression systems. Additional embodiments provide for screening assays for identifying IGFBP-3 receptor antagonists or agonists, methods for modulating IGF-independent IGFBP-3 responses of cells expressing IGFB...

A holder in various embodiments, holds a previously opened, now recapped, bottle partially filled with an effervescent liquid, in an inverted position, wherein the effervescent liquid forms a seal about the interior of the replaced cap, to prevent the escapement of effervescent gasses. The holder can also be used in the storage, display, and transporting of unopened containers in a non-inverted position due to the congruent positioning of the vertical supports used to stabilize the containers in...

Continuously conveyed flexible flat structures, especially printed products, infed in an imbricated formation, are turned such as to retain their original imbricated product formation. This is accomplished by accelerating the flexible flat structures such that they are singled and then in such singled condition are deflected about a deflection axis directed transverse to the product infeed conveying direction. Thereafter the singled turned flat structures are decelerated and transported away in ...

A thin-walled, cup shaped container molded of polypropylene, or other suitable material, is formed with a tamper-evident band initially positioned outside the lip at the top of the container wall. The lower edge of the band is connected to the container by spaced frangible bridges. A lid closes off the top of the container and has an outer and inner skirt respectively fitting outside and inside the container lip. The upper end of the band is formed into an annular inward projection overlying the...

This invention relates to a sensor suitable for detecting the collision speed of a car or the like. The sensor has a pair of spring members which are supported so as to intersect with each other between free ends and fixed ends thereof, a mass which is supported in the intersecting portion of the spring members, and electric contact members which are arranged at an operative position of the mass. When an intense impulsive force acts, the mass moves onto the operative position side against the sp...
