  • Hoist elevating means
    Patent number: 4649764
    Abstract: A clothes hoist comprising a bearing block secured to the outer surface of the fixed lower standard of a clothes hoist but having an annular projection which extends through an aperture in the wall of the lower standard and into an aperture in the side wall of a tubular inner member to thereby support the tubular inner member, the tubular inner member itself supporting a nut which threadably engages a non-circular threaded stem which, upon rotation of the nut, raises or lowers the upper standard. Rotation is effected by rotating a handle on the end of a driving pinion skirt journalled in the bearing block, and having a driving pinion on its inner end which meshes with a driven pinion on the nut. A body surrounds the lower standard and overlies an outwardly projecting portion of the bearing block.

  • Method of controlling actuator by applying driving pulse
    Patent number: 4644475
    Abstract: A controlling method for pulse application to an actuator using a digital controller.A controlling method of an actuator, wherein a deviation is obtained from a command value and its feedback value, the absolute value of said deviation is determined whether it is larger than the minimum reference deviation corresponding to the dead zone, and only when the absolute value of the deviation is larger than the minimum reference deviation, the actuator is driven by a pulse having an application period proportional to the absolute value of the deviation plus a minimum application period stored in the memory of the digital controller.The minimum application period stored in the memory is increased or decreased and renewed depending on the judgement whether the movement volume of the actuator at each pulse application was under, proper or over.

  • Isolator switch with interlock
    Patent number: 4633047
    Abstract: An electrical isolator has an insulated housing with input and output conductors (1, 2) therein. A spring contact (6) is mounted within the housing for movement between open and closed positions. An insulating shroud (15) fully shields that part of the bridging contact accessible through an access opening of the housing. Manually operable pressure applying structure may be operated when the bridging contact is in the closed position to control that contact between a tightened condition applying pressure between the bridging contact and the conductors without the use of springs, and a free condition wherein the contact pressure is reduced. An interlock assembly prevents engagement and disengagement of the operating member with the pressure applying structure unless the bridging contact is located in either the closed or open position.
