Patent number: 10667023Abstract: Systems and methods for continually measuring and calculating performance of a hot water or a system are described. A central monitor receives and processes information from hot water or steam field devices. A mobile device can communicate with the central monitor and display processed data from the central monitor regarding field devices associated with the mobile device. The central monitor can determine and send control parameters, maintenance reminders and other information to the mobile device or to a monitor at an enterprise location. Data is sent to the mobile device from the central monitor when there is a quality communication connection. If the mobile device is in the field with a poor or no communication connection, it stores updates and pushes the changes to the control monitor when a quality communication connection is reestablished.Type: GrantFiled: May 20, 2016Date of Patent: May 26, 2020Assignee: ARMSTRONG INTERNATIONAL, INC.Inventors: Kurt Armstrong, Thomas Jack Secord

Patent number: 6099260Abstract: A pump trap assembly with multiple pivot axes. The pump trap assembly includes a mounting bracket for mounting the trap assembly to a structure. A first pivot arm having a length is pivotally mounted to the mounting bracket about a first pivot axis. A second pivot arm having a length is also pivotally mounted to the mounting bracket about the first pivot axis. A spring is used to bias the first and second pivot arms toward each other. A float arm having a length is also pivotally mounted to the mounting bracket about a second pivot axis. The second pivot axis is a distance from the first pivot axis. An actuator is pivotally mounted to the second pivot arm about a third pivot axis. The third pivot axis may be the same as the second pivot axis or may be a distance from the first and second pivot axes. Movement of the float arm in a first direction causes the spring to urge the second pivot arm in the first direction and move the actuator in the first direction.Type: GrantFiled: June 17, 1998Date of Patent: August 8, 2000Assignee: Armstrong International, Inc.Inventor: Charles M.
