An electrically operated valve actuator effective for shifting a valve (10) between open and closed positions is disclosed, the valve actuator comprising a movable member in the form of a valve stem (21) connected to a valve body (14), the movable member being driven by an electric motor (22) in linear motion between valve closing and valve opening positions, wherein electrical power to the motor is supplied via a current (25) control including a supplied current detection device. The movable member is designed for an idling length of travel (L) in the opening and closing directions during which the valve (10) is either fully open or fully closed, and the movable member is associated with buffer means (30) that during the idling length of travel gradually increases the torque and power required to move the movable member further in the open and closed positions of the valve (10), respectively. |

A location and retention component is provided for positively locating an overspeed guard and retaining a centrifugal actuator at an optimum positional relationship relative to each other. The system includes a first and second retention element removably engagable to the output shaft of a motor and axially fixable to the shaft at corresponding locations to maintain the optimum positional relationship. The first retention element serves as a positive stop for assembling the overspeed guard on the motor shaft, while the second retention element ensures that the centrifugal actuator is properly placed within the overspeed guard. |

A rotor of a motor has a bearing mounted thereon, the bearing having a tab which is urged in one direction by the fluid friction of the lubricant in the bearing, the tab being urged against a spring, the tab actuating a micro-switch. The force exerted by the tab on the spring is a function of the rotor speed. Upon reduction of rotor speed the spring urges the tab rearwardly so that the micro-switch open circuits in turn disconnecting power from the motor which comes to a standstill. |

An endless-conveyor monitoring switch assembly includes an elongated frame having a shaft journaled for rotation therein and extending longitudinally therealong. A drive wheel is attached to and rotatable with the shaft at a first end of the elongated frame and a detecting switch is attached to the shaft at the opposite end of the elongated frame. A seesaw, U-shaped, mounting member is attached to the elongated frame at a point intermediate the drive wheel and the detecting switch for mounting the elongated frame on an endless-conveyor cable support. The mounting member allows the weight of the elongated frame and its attachments to pivot the frame in a seesaw manner to bring the drive wheel into contact with the endless conveyor. The detecting switch includes a conductive disc mounted on the shaft adjacent to a pendulum having permanent magnets and mercury switches mounted thereon. When the shaft rotates the disc above a predetermined speed, the permanent magnets on the pendulum cooperate with eddy currents in the disc to pivot the pendulum and thereby actuate the mercury switches. |

A sensor for a positive or negative acceleration responsive switch for detecting an acceleration exceeding a predetermined level applied to a moving body. A bowl having a reverse conical wall at its upper peripheral surface is mounted horizontally to the moving body, and a turning coil which forms a part of an oscillator circuit is disposed at the lower portion of the bowl. Within the bowl, a conductive medium such as metallic ball or conductive liquid, e.g., mercury is placed so that it is displaced under an acceleration applied in any horizontal direction. The acceleration may be detected based on the distance of the conductive medium from the tuning coil.
