Publication number: 20090068060Abstract: An apparatus for monitoring corrosion in a pressurized system such as a water-based fire protection system comprising a corrosion monitor mounted within a section of the system containing fluid, wherein the corrosion monitor comprises a surface comprising at least one point of weakness wherein corrosion of a point of weakness causes a change in pressure in an interior chamber of the monitor, which change can be to provide a signal alerting monitoring personnel.Type: ApplicationFiled: June 27, 2008Publication date: March 12, 2009Inventors: Michael J. Alfermann, Michael D. Kirn, David L. Royse, Richard L. Ulrich

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. Royse

Patent number: 7137408Abstract: A universal valve switch for signaling the operative state of a valve assembly is disclosed that is attached to the body of the valve assembly using a bracketing arrangement. The valve switch comprises a housing defining a chamber and an aperture formed through the housing that communicates with the chamber. The valve switch may include a contact arrangement having a spring-loaded plunger that is extendable through the aperture with the plunger being operatively associated with the contact arrangement for selectively transmitting a signal to a remote panel whenever the lever is rotated out of contact with the plunger. In other embodiments, the contact arrangement may be replaced with various types of sensor assembly.Type: GrantFiled: August 23, 2005Date of Patent: November 21, 2006Assignee: Potter Electric Signal CompanyInventor: David L. Royse

Patent number: 6860331Abstract: A single-piece manifold for use with a residential or other building sprinkler system is disclosed which comprises a body having an inlet in communication with a water supply and an outlet that communicates with a sprinkler system having a conduit adapted for fluid flow formed between the inlet and the outlet. The body includes a main valve that provides a means of manually shutting off communication with the water supply and a combination pressure relief and test valve for draining and testing the sprinkler system. A pair of check valves are positioned across the conduit for preventing fluid flow therethrough when the sprinkler system is inactive with a space being defined between the first and second check valves for communication with a vent passageway. The vent passageway communicates with atmosphere and prevents false alarms due to water surges in the supply line.Type: GrantFiled: November 14, 2001Date of Patent: March 1, 2005Assignee: Potter Electric Signal CompanyInventors: William A. Hagen, David L. Royse

Patent number: 4739134Abstract: A valve monitoring switch is operated by an adjustable length rod whose end senses the position of a valve, for example, a water supply valve. The rod, enclosed by an assembly-mounting nipple, is so pivot-mounted as to be capable of movement in a planar arc, whose plane is substantially coincident with or parallel to the component of valve movement as between its open and closed positions. When the rod is pivoted through a small arc of movement, against the bias of conventional electrical switches, they signal the valve position or its change. To effect installation without damage to the switch assembly, an angularly adjustable mounting socket for the nipple is provided; also, the rod length is adjustable, so that during installation it may be retracted alongside the electrical switch assembly; and after installation may be extended to and fixed in a position in which it will sense the state of the valve.Type: GrantFiled: May 20, 1987Date of Patent: April 19, 1988Assignee: Potter Electric Signal Co.Inventors: Robert E. Hopmann, David L. Royse
