Abstract: A piston having a longitudinal axis and opposing proximal and distal axial ends is manufactured by a method including molding a partially formed piston body and then molding the piston. The partially formed piston body is molded by placing a first rubber sheet and an inert film between die plates of a first forming tool, vulcanizing the first rubber sheet and the inert film between the die plates of the first forming tool, and blanking out the partially formed piston body from the first rubber sheet and the inert film. The piston is then molded by placing the partially formed piston body into a second forming tool, placing a second rubber sheet into the second forming tool, vulcanizing the second rubber sheet and the partially formed piston body together, and blanking out the piston from the second rubber sheet at a trim edge spaced apart from the inert film.

Abstract: A pharmaceutical syringe piston having a longitudinal axis includes a body having a central face portion with a first outer circumference and maximum first diameter. A cylindrical sealing portion proximate the central face portion has first and second axial ends and a wall extending therebetween. The wall has a second outer circumference and a second diameter essentially constant along the longitudinal axis between the first and second axial ends of the cylindrical sealing portion and is larger than the maximum first diameter. An annular curved portion has a maximum outer diameter less than the second diameter and connects the first axial end of the cylindrical sealing portion to the first outer circumference. An inert film encloses the central face portion and at least part of the annular curved portion and has an outer boundary between the first axial end of the cylindrical sealing portion and the first outer circumference.

Abstract: The current invent relates to the construction and application of a three-line breeding system in the bay scallop×Peruvian scallop hybrids. The said three-line consists of a male sterile line, a maintainer line and a restorer line. A combination of male sterile line and maintainer line is obtained by continuously backcrossing the male sterile individuals selected from F1 inter-specific hybrid families with sperm of the selfing family of the sperm-providing Peruvian scallops until the progenies are all male sterile. The restorer line is obtained by continuously backcrossing selected individuals from the male sterile line with sperm of the selfing family of a Peruvian scallop until the progenies are all hermaphroditic and exhibit excellent production traits. Commercial male sterile brood stocks are produced by backcrossing the male sterile line with the maintainer line and commercial hybrid spats are produced by backcrossing the male sterile line and the restorer line.
