  • Patent number: 6748967
    Abstract: Couplers for joining actuators to valves are configured to allow their affixment to different makes and models of actuators and valves, thereby allowing an off-the-shelf S coupling solution and avoiding the need to specially construct a coupler which is only adapted to connect whatever valve and actuator that are desired for coupling. The couplers include a shaft/stem bore which accommodates the torque-transmitting components of the valve and actuator to be coupled, and sets of affixment holes surround the shaft/stem bore, with these affixment holes being arrayed in patterns matching those of different common valves and actuators. Thus, a coupler may affix to different valves or actuators provided the appropriate affixment holes are chosen. The couplers may be formed as single-piece or multi-piece units.

  • Patent number: 5258743
    Abstract: A piezoelectric resilient arm contacts a projected object and establishes a reference relative to sensitivity means and differential detector means including feedback coupled amplifier means which operates in cooperation with a balanced square wave generator means for producing a switched output upon detecting motion. An alarm signal is produced which has a duration related to the rate of change of movement of the piezoelectric resilient arm. Programmable delay means appropriately enables an annunciator and/or wireless communication link to a system controller.
