Patent number: 12036432Abstract: A monitoring and testing system which is designed to automatically seal off the system from its gas supply and monitor internal pressure during that time to perform regulatory testing. The scheduling can be automated and can be done without maintenance personnel having to monitor the time passage and pressure manually. The system may also be designed to monitor operation of the air compressor, or related gas supply device, and evaluate if the operation of the gas supply is operating in a fashion indicative of a larger than desired leak. This effectively allows the system to monitor pressure changes during regular operation and on a somewhat continuous basis.Type: GrantFiled: April 23, 2021Date of Patent: July 16, 2024Assignee: Potter Electric Signal Company, LLCInventors: Mike Henke, Timothy Decker, Jason Webb, Andrew Kaempfer

Patent number: 11291871Abstract: A gas supply system primarily designed for use with fire sprinkler systems which includes a control system which uses flow demand to automatically determine the mode of operation and switch between providing air and nitrogen. The gas supply system can operate either in standard nitrogen generation mode where nitrogen is supplied to the reservoir tank and/or sprinkler system or in a bypass mode, where sufficient pressure is only obtained by directly supplying air. The gas supply system can provide for improved safety in operation as well as the ability to operate the sprinkler system primarily when filled with nitrogen supervisory gas.Type: GrantFiled: January 30, 2018Date of Patent: April 5, 2022Assignee: Potter Electric Signal Company, LLCInventors: Joshua Tihen, Timothy Decker

Patent number: 7992527Abstract: A water feed controller which can provide for the addition of a preset fixed amount of water to be added after a low water condition is removed. This system provides for a preset fixed amount of water to be added to a boiler above the amount which triggers the low water condition. This generally inhibits excess cycling from the boiler operating at its minimum safe water level as well as inhibiting overfilling of the boiler. Further, there is discussed a water feed controller which can measure the amount of water added over a prior predetermined period (such as 30 days) which serves as a floating window of time so that a leak or other condition resulting in overly frequent filling can be detected quickly.Type: GrantFiled: December 9, 2005Date of Patent: August 9, 2011Assignees: Potter Electric Signal Company, LLC, Taco, Inc.Inventor: Jeffrey C.

Patent number: 7766031Abstract: A valve system for collection and removal of condensation from a gas-pressurized fluid system. In one embodiment a single valve is used, having inlet, outlet and condensate collection ports and a valve body capable of movement between a position which connects the inlet port to the condensate collection port and a position which connects the condensate collection port to the outlet port. The valve is formed such that the inlet port is not connected to the outlet port while the valve is moved between the two positions, so that the pressurized system is not depressurized. A second embodiment uses two coupled valves replacing the single valve.Type: GrantFiled: October 24, 2006Date of Patent: August 3, 2010Assignee: Potter Electric Signal Company, LLCInventors: Bruce M. Platusich, Henry J. Zawada

Patent number: 7706989Abstract: Systems and methods for evaluating probe signal level readings in a manner that allows a low water detector to distinguish between a probe that is under a fluid level, or is above the fluid level and either being splashed or is within a foam. Low water detectors which utilize these systems and methods are also provided. The detectors generally utilize a representative probe reading, and a dynamic indicator between probe readings, for a set of probe readings taken in a time period to detect low water levels, foam, or surge.Type: GrantFiled: April 9, 2008Date of Patent: April 27, 2010Assignees: Potter Electric Signal Company, LLC, Taco, Inc.Inventors: Jeffrey C.

Patent number: 7293576Abstract: A single-piece manifold comprising a body having an inlet in communication with a water supply and an outlet that communicates with a sprinkler system having a main conduit adapted for fluid flow between the inlet and the outlet is disclosed. The body includes a main valve that provides a means of manually shutting off communication with the water supply and first and second check valves positioned across the main conduit for preventing fluid flow therethrough until the sprinkler system is activated. The single-piece manifold has a reduced pressure arrangement comprising a valve member that vents water that may build up between the first and second check valves in order to prevent the back flow of contaminated water from the sprinkler system to the water supply.Type: GrantFiled: March 28, 2005Date of Patent: November 13, 2007Assignee: Potter Electric Signal CompanyInventor: David L.

Patent number: 7243540Abstract: A low-water cut-off system [A] determines if fluid [W] within a boiler or other enclosure drops below a predetermined level within the enclosure. A signal generator introduces a signal into the enclosure so that the signal is present for sensing at the predetermined level, where a probe is provided for sensing the signal if present as occurs if the water is at the predetermined level. A control, which includes a microcontroller, is responsive to the probe for providing a control function in response to whether the signal is so sensed by the probe, and so to determine if water has dropped below the predetermined level. The function may be causing alarm signalling or boiler heating cut-off. Self-test and time delay features are also included. Provision is made so that the control compensates for variation in electrical conductivity of the water through which the probe signal is sent, including circuitry to adjust for a wide range of possible purity levels.Type: GrantFiled: December 5, 2003Date of Patent: July 17, 2007Assignee: Potter Electric Signal CompanyInventor: Jeffrey Merwin

Patent number: 6940409Abstract: A method and apparatus for monitoring fluid flow in a pipe or at an exit of the pipe and detecting a fault. The system includes an acoustic generator which is activated by the fluid flowing in the pipe or at the exit of the pipe. The acoustic generator sends an acoustic signal, which may have a distinctive signature, through the fluid flowing in the pipe. The acoustic signal is received by a remote upstream acoustic receiver and is translated into an electric signal supplied to a signal processor.Type: GrantFiled: August 8, 2002Date of Patent: September 6, 2005Assignee: Potter Electric Signal CompanyInventor: Timothy M.
