  • Patent number: 6164122
    Abstract: A plurality of test chambers or fixtures are operable for successively testing a plurality of condoms, respectively, in an automated manner. Each test chamber for testing a condom includes a housing containing a porous liner having an interior cavity conformed to the exterior shape of a condom to be tested, whereby a holder carrying the condom is inserted into the liner, a closed pathway for gas flow is provided between a gas port of the holder and the interior volume of the condom, for permitting the condom to be inflated with the gas, causing the exterior walls of the condom to be pushed against opposing inside walls of the liner, permitting gas passing through holes in the condom to flow through pores in walls of the liner to another gas port of the housing for detecting unacceptable holes in the condom using differential pressure techniques and/or gas tagging.

  • Patent number: 6044693
    Abstract: A plurality of rolled-up prophylactic devices are passed through a plurality of pairs of unroller tubes with a randomizer vessel being coupled between each pair of unroller tubes, the randomizer vessels functioning to randomly reorient a portion of rolled-up ones of the prophylactic devices passing therethrough to move a rolled-up portion of each of the latter to the outside of the associated prophylactic device to facilitate unrolling of the same as it passes from the randomizer vessel into another one of the unroller tubes. A separator tank has an inlet port coupled to an output end of the last occurring unroller tube, for collecting the processed prophylactic devices, and for applying a vacuum to the system for sucking the prophylactic devices through the unroller tubes and randomizer vessels.

  • Patent number: 5846835
    Abstract: The invention relates to a method of making a laminated substrate for use in an immunodiagnostic device and a machine or apparatus for marking the substrate with reagent. The method of forming the laminated substrate creates a rollable chromatographic medium. The chromatographic medium can be biphasic or multiphasic. The biphasic chromatographic medium comprises a capture medium precast onto a plastic backing and a release medium. The release and capture media are bonded to a liner material such as a plastic film. The multiphasic chromatographic medium comprises a capture medium precast onto a plastic backing, a release medium, and a sample absorbent medium. The capture medium, the release medium and the sample absorbent medium are disposed on a liner material such as a plastic film. The biphasic and multiphasic laminates are prepared for use as immunoassays by a specially adapted machine or apparatus.

  • Patent number: 5438861
    Abstract: Condoms and other sheaths are tested for holes by drawing the sheath over a hollow porous mandrel having smaller openings at its head end than in the rest of its body, providing a difference between the pressure within the mandrel and the pressure outside the condom, and comparing the rate of change of pressure within the mandrel with the rate of change of a reference pressure. The mandrel is shaped such that powder particles in the inner surface of the condom are moved toward the head of the mandrel where the smaller openings are when a condom is drawn onto it, for substantially preventing the powder from clogging the larger pores below the head region of the mandrel.
