  • Slide smearing device
    Patent number: 4151915
    Abstract: A device for smearing on slides a drop of liquid placed on a predetermined point on each slide has slide magazines containing a plurality of slides with the uppermost slide in each magazine having its upper face exposed for the reception of a drop of liquid towards one end thereof. Spreaders are adjacent the other ends of the slides. Means advance the spreaders out of contact with the slides, lower the spreaders into contact with the slides as they approach said predetermined points on the slides and slow the advance of the spreaders as they approach said points. The spreaders are retracted and the angle between each spreader and slide decreases to thin the smear of liquid. Means advance the uppermost slide in each magazine forwardly out of the magazine a predetermined distance to facilitate the removal of the slide by hand after the desired smear is made.

  • Coated substrate having a low coefficient of friction hydrophilic coating and a method of making the same
    Patent number: 4119094
    Abstract: A substrate is coated with a polyvinylpyrrolidone-polyurethane interpolymer. In the method, a polyisocyanate and a polyurethane in a solvent such as methyl ethyl ketone are applied to a substrate and the solvent evaporated. If the substrate is a polyurethane, only the polyisocyanate need be employed. Polyvinylpyrrolidone in a solvent is then applied to the treated substrate and the solvent evaporated.

  • Permanent automatic rotor balancer for shafts operating above critical speed
    Patent number: 4117742
    Abstract: A pair of balancing weights are mounted on opposite sides of the center line of the rotor for movement about the axis of the rotor. The weights are automatically locked against movement about the axis of the rotor when the rotor is rotating below critical speed and automatically released for free movement about the axis of the rotor when the rotor is rotating above critical speed. The weights are exemplified as roller cages. The balancing weights are variously locked by mechanical clutches actuated at critical speed. The clutching for the weights is either individual or such that the weights are necessarily locked against movement and released simultaneously. Centrifugal force is used to control the clutches.
