  • Patent number: 5263587
    Abstract: An inflatable pouch for packaging a circuit board is formed from two superposed sheets of an electrostatically dissipative plastic. The plastic sheets are welded together to form two air chambers therebetween, each having a plurality of passages therein and they are folded over along a transverse centerline so as to form a bottom end along the centerline, an open end opposite the bottom end and opposing front and rear walls. The side portions of the front and rear walls are welded together to form the side edges of the pouch. The passages in the front wall adjacent the open end of the pouch include enlarged portions which are transversely offset from and interengageable with corresponding enlarged portions in the rear wall to prevent a circuit board from sliding out the top of the pouch. Both air chambers are inflatable through a single inlet aperture which is sealable with a clamp.

  • Patent number: 4907425
    Abstract: A method of forming a jewelry clutch includes the steps of molding an inner gripping piece from a substantially solid, elastomeric, thermoplastic material and forming a plastic outer casing having an opening at one end thereof around the gripping piece. The method further includes the step of inserting an elongated stud or post into the opening in the casing so that the post penetrates through the gripping piece to form a substantially resealable opening therein. The clutch formed by the method can be installed on the post or stud of a jewelry item so that the stud passes through the opening in the outer casing and is received in the resealable opening in the gripping piece to releasably retain the post in the clutch.
