| A liquid level control module comprising an elongated tubular housing immersible through a surface of a liquid and into a bulk volume of the liquid, and first, second, and third electrical switches, and first and second floats movable along the tubular housing. The first electrical switch is disposed within a lower portion of the tubular housing, the second electrical switch is disposed within an intermediate portion of the tubular housing, and the third electrical switch is disposed within an upper portion of the tubular housing. Each of the switches has an open state and a closed state. Motion of the first float relative to the first switch changes its state. Motion of the second float relative to the second switch changes its state, and motion of the second float relative to the third switch changes its state. Thus a two-float module may provide three level control signals. | ||||||
| 123 | Fuse Cutout Monitoring and Indication Device | US15458575 | 2017-03-14 | US20170263406A1 | 2017-09-14 | Craig Hamilton Rosenquist |
| A device for monitoring and indicating a fuse tube detachment from a fuse cutout assembly contains a structural body, a tilt switch, a power source, a visual indicator, and an attachment mechanism. The attachment mechanism is used to mount the device onto the fuse tube. The tilt switch monitors the position of the fuse tube. More specifically, when the vertical position of the fuse tube changes to the dropped position the tilt switch is triggered. Thus, the visual indicator is illuminated. The illumination aids in the process of discovering the detached fuse tube. In addition to the visual indicator, the device can also be equipped with a wireless communication device and an alarm system. The wireless communication device can be used to provide the exact location of the detached fuse tube. On the other hand, the alarm system can be used to expedite the process of discovering the detached fuse tube. | ||||||
