  • Patent number: 9352492
    Abstract: An injection blow molding (IBM) system and method for forming a plurality of parisons and molded articles. The IBM system includes an injection station having upper and lower die sets and a plurality of upper and lower mold half blocks each attached to a respective die set. Each of the upper mold half blocks has a corresponding lower mold half block with which it cooperatively defines one or more cavities for forming the exterior shape of the body of one or more of the parisons. The individual, independent attachment of the mold half blocks to the die sets allows easy individual replacement of faulty or worn mold blocks. Further, such an independent attachment configuration also permits the mold half blocks of each die set to be spaced from one another, so as to reduce thermal expansion problems and ease dimensional tolerances required for the width of the mold half blocks.

  • Patent number: 5413115
    Abstract: A pen-size syringe has a needle secured to a hub at one end and a valve located near the hub and slidable transversely of the syringe axis by the forefinger of the user, from a closed condition, to a sampling condition, to a needle venting condition. A plunger in the syringe is axially slidable by manually pulling a portion projecting out the other end of the syringe to establish a vacuum in the syringe when the valve is closed. A latch is provided to keep the plunger in the vacuum establishing position. With the vacuum established, and the needle point situated at the sampling site, the valve is operable by the index finger to open the vacuum chamber to the needle for taking the specimen, following which the finger pushes the valve to the further position venting to needle to atmosphere, for removal of the needle, and any contained sample.
