Abstract: Erythropoietin analogs having at least one additional site for glycosylation, or a rearrangement of at least one site for glycosylation are disclosed. The invention also relates to DNA sequences encoding said erythropoietin analogs, and recombinant plasmids and host cells for analog expression.

Abstract: A meter run has a meter tube fitting of a configuration which includes an annular cavity. The cavity has confronting faces spaced from one another. An orifice plate holder is received in axially aligned relationship therebetween so that flow must occur through the central orifice formed in the orifice plate. A meter tube insert is positioned within the meter tube fitting and includes reduced diameter confronting annular flanges having faces spaced from one another substantially the same amount as the spacing of the confronting faces of the cavity. An adaptor assembly includes an outer annular gasket, an annular main support body, an inner annular gasket, and an orifice plate. The orifice plate is mounted within the inner annular gasket, the inner annular gasket is mounted within a passageway formed through the main support body, and the main support body is sealingly mounted within the outer annular gasket.

Abstract: A ball check valve assembly for assuring unidirectional flow through a meter run. The valve assembly includes a plate member adapted to be placed between the confronting flanges of a pipeline or meter run and positioned so that back flow cannot occur back through the meter run. A passageway formed through the plate member extends into an enclosure which has a valve seat formed on the top wall surface thereof through which unidirectional flow can occur. One wall surface of the enclosure extends up and then bends towards the plate member. The marginal free end of the bent part of the back plate member is apertured to admit the ball to be received therein, thereby capturing the ball between the seat and aperture in a manner that enables the ball always to gravitate back into sealed relationship respective to the seat, and yet the ball can be displaced sufficiently far enough from the seat to achieve relatively unobstructed flow.

Abstract: A die cut one piece interlocking outfold container has interlocking of inside and outside flaps. A cover length flap of the container folds outside of a body length flap, and cover width flaps fold inside of body width flaps. The particular configuration results in the container having plural thickness front, back and side walls, which increases the stacking strength of the container.
