  • Protective needle cover
    Patent number: 5885255
    Abstract: The instant invention pertains to a flexible needle cover which surrounds a hypodermic needle on a syringe so that when the syringe is used the flexible needle cover retracts to expose the needle and after use the flexible needle cover returns back to its original shape covering the needle. The flexible needle cover of the instant invention is a bulb shaped elastomeric material that is capable of retracting during use with the application of slight pressure and returning to its original shape after the release of the pressure.

  • Trimodal air/fluid driven sash operator fume hood
    Patent number: 5759096
    Abstract: A fume hood sash operator and fume hoods containing such sash operators. The sash operator is constructed to operate from a pressure fluid cylinder which has no outside operating parts with respect to the movement of the piston in the cylinder. The unique construction of the pressure fluid cylinder makes it very useful for fume hood construction because of the overall small dimensions of the pressure fluid cylinder and the ability to start the piston by overcoming the inertia of the piston using very low air or fluid pressures.
