First Claim
Patent Images
1. An apparatus for remote inspection of portable tanks, the apparatus comprising:
- a portable tank defining a volume;
a gauge disposed in communication with the volume defined by the portable tank, the gauge detecting and displaying a pressure condition of a content contained within the volume with a gauge pointer;
a Reed switch sensor that detects an out-of-range pressure condition of the content contained within the volume based upon a proximity of the gauge pointer to a position indicating the out-of-range pressure condition;
an electronic circuit including a timer set to actuate at least one of a visual signal and an audio signal after a recommended period between inspections of the gauge, unless the timer is reset during the recommended period; and
an electronic circuit disposed in communication with the gauge and adapted to signal to a remote central station upon detection of the out-of-range pressure condition by the Reed switch.

Abstract
An apparatus for remote inspection of fire extinguishers at one or a system of fire extinguisher stations includes, e.g., at each fire extinguisher station: a detector for lack of presence of a fire extinguisher in its installed position at the fire extinguisher station; a detector for out-of-range pressure of contents of the fire extinguisher at the fire extinguisher station; a detector for an obstruction to viewing of or access to the fire extinguisher at the fire extinguisher station; and a device for transmission of inspection report information from the fire extinguisher station to a remote central station.
