  • Patent number: 5233884
    Abstract: A connection between a drive member and a driven member comprises a first nickel titanium alloy wire interconnecting the drive member and a rigid link and a second nickel titanium alloy wire connecting the rigid link and the drive member. Such a wire, when properly heat treated, has a high tensile and also a high compressive strength while at the same time the wire will bend readily if there is misalignment between the longitudinal movements of the drive and driven members. Thus the assembly functions as a two-ball joint drive line similar to that used in automobiles. A preferred usage is in driving the plunger of a syringe in a dosage metering system from a moving machine element where the syringe bore and direction of movement of the machine element may be slightly out of alignment. Wear of the syringe seals is reduced.

  • Patent number: 5197343
    Abstract: A driven member has flat parallel top and bottom surfaces over at least a portion of its length. A motor actuated drive roller is mounted between two parallel, spaced side plates between which the driven member reciprocates and bears against the driven member. Back-up rollers engage the drive roller to prevent the pinion from backing away from the driven member. A spring-mounted pressure roller bears against the side of the driven member directly opposite the drive roller. As the motor turns the drive roller, the latter frictionally engages the driven member and causes the latter to move linearly without the backlash characteristic of rack and pinion mechanisms.
