Abstract: Soluble polypeptides of human prolactin receptor, corresponding to products expressed from differentially spliced mRNA and obtainable from various human tissues, are reported and recombinant molecules containing nucleic acid sequences encoding the soluble polypeptides of human prolactin receptor can be constructed and inserted into expression vectors for production in transformed host cells.

Abstract: A golf shoe stud comprises a molded plastics body enabling the stud to be mounted in the underside of the shoe, a steel stem which extends through the body and forms a frustoconical stump projecting below the body, a thin steel lamina which overlies the underside and edges of the plastics body, and a nose of tungsten carbide which is mounted on the stump. The nose is bonded to the stump by brazing, and an upper end portion of the steel stem is out-turned for securement of the body and the lamina between the out-turned portion and the nose. The stud may be of a replaceable kind in which the plastics body forms a threaded spigot and a sole-engaging flange, or it may be of a permanent kind in which the molded body is arranged to be incorporated in manufacture into a molded shoe sole.

Abstract: Aqueous emulsions, at least 80% of which have been polymerized, are treated by a process which comprises the separate steps of: a) initially treating the emulsion with a sufficient amount of a free radical generator in an amount and for a time sufficient to reduce the residual monomer content to from about 1500 to about 6000 part per million, and b) subsequently subjecting the emulsion to steam stripping under vacuum, without significantly degrading or destabilizing the emulsion, to thereby reduce the residual monomer content to from about 5 to about 500 parts per million.

Abstract: In a stud and socket combination for studded footwear, a moulded plastics socket (1) provides a threaded axial hole (5) bounded by an inner ring (9). A co-axial outer ring (10) is radially separated from the inner ring to leave an annular space (11). A plastics stud moulding (19) comprises an externally threaded sleeve (21) which can be screwed into the socket hole and a co-axial ring (26) which is spaced radially outwards from the sleeve to slide over the inner socket ring (9) and enter the annular space (11) when the stud and socket are assembled. Four part-cylindrical webs (29) project axially from the ring (26) into the space (11) and provide four axially-extending locking ribs (28) at 90.degree. intervals which project radially outwards from the ring. On the inner surface of the outer ring (10) of the socket are formed four corresponding formations providing recesses (15) to receive the ribs (28). Each recess is bordered on one side by a lead-in ramp (16) and on the other side by a stop block (17).
