Patent number: 11655905Abstract: A multi-port valve is provided. The multi-port valve includes a housing which defines an internal cavity. The housing further includes a plurality of ports. Each of the plurality of ports is in communication with the internal cavity. A shell body is rotatably disposed within the internal cavity. A seal member is also provided which has a plurality of openings and surrounds the shell body such that it circumscribes the shell body within the internal cavity.Type: GrantFiled: April 4, 2018Date of Patent: May 23, 2023Assignee: Robertshaw Controls CompanyInventors: Joe Ledvora, Philip C. Hawken, Thomas J. Davern

Patent number: 10374338Abstract: A connector bridge for a packaged circuit element is provided. The connector bridge includes a connector bridge body defining a mounting axis. It includes a first plurality of terminal receivers at a first location and a second plurality of terminal receivers at a second location. The pluralities of terminal receivers are arranged closer to a side of the connector bridge body than to the mounting axis to receive and electrically connect with terminals of the packaged circuit element in the first wiring orientation. The connector bridge includes a wiring connector at a third location. The wiring connector extends radially outwards of an outermost perimeter defined by radially outermost sides of the packaged circuit element. The first, second and third locations are at different locations. The wiring connector is electrically connected with the at least first and the second terminal receivers and defines a second wiring orientation.Type: GrantFiled: December 22, 2017Date of Patent: August 6, 2019Assignee: Robertshaw Controls CompanyInventors: Philip C. Hawken, James E. Pearson

Patent number: 7533682Abstract: A system and method of flow rate compensation is provided to allow precise volume dispensing over widely varied and varying input process media pressure and flow conditions. This system utilizes empirical data of actual flow rate versus flow rate measured by a flow meter to characterize flow meter non-linearities. This data is used to generate a compensation control curve. The system controller receives flow data from a flow meter in the field and calculates pulse duration of the output of the flow meter. The compensation control curve is then used to determine the volume of process media flowing at any given time. This instantaneous volume information is added to an accumulator to determine the volume of process media dispensed. This volume is compared to a target volume. Once this target volume is reached, the flow of process media is stopped.Type: GrantFiled: February 17, 2005Date of Patent: May 19, 2009Assignee: Robertshaw Controls CompanyInventors: Bogdan Gheorghe, Philip C.

Patent number: 7511239Abstract: A method and apparatus are provided for simultaneously changing multiple liquid level settings in a liquid-level switch including a diaphragm actuated pressure switch apparatus having a first and a second switch, through use of an actuator apparatus including a single control knob shaft rotatably connected to the pressure switch apparatus and having a first and a second cam fixedly attached to the shaft for rotation therewith, the first cam being operatively connected to provide a biasing force against actuation of the first switch, and the second cam being operatively connected to provide a biasing force against actuation of the second switch.Type: GrantFiled: March 31, 2005Date of Patent: March 31, 2009Assignee: Robertshaw Controls CompanyInventors: Philip C. Hawken, Jerome C. Klopp, Robert J. Van der Linde, Paul H. Tuma

Patent number: 6722575Abstract: An adapter for use with a mixing valve, an automatic temperature regulating mixing valve, and a method of providing automatic temperature regulation for a fluid mixing valve are provided. The adapter includes an inlet adapted to attach to an outlet of a mixing valve, and at least one temperature sensing switch positioned to sense the temperature of fluid flowing through the adapter. The thermal sensing switch activates at a predetermined temperature to close its internal contacts. This contacts are wired between the line inputs of the electrically controlled valves governing the flow of fluid into each of the hot and cold fluid inlets of the mixing valve. Both or either a high and low temperature switch may be used. The adapter may also include a flow control element.Type: GrantFiled: November 19, 2002Date of Patent: April 20, 2004Assignee: Robertshaw Controls CompanyInventors: Kelly S. Gagne, Philip C. Hawken, James E. Pearson

Patent number: 5584560Abstract: A spotlight is provided that employs stationary motors for positioning a light beam at a desired azimuth and elevation such that there is no blind spots of the light beam at the zenith of the azimuth and elevation. A drive train rotates the spotlight about a horizontal axis and allows the motor driving the rotation to have a stationary mounting in a base while at the same time providing the light beam of the spotlight with a range of elevation that exceeds 90 degrees from a horizontal reference plane at any desired azimuth. More particularly, a stationary motor drives a capstan, which includes a spool that winds and unwinds a cable connected to a lamp assembly of the spotlight for positioning the light beam at a desired elevation. The cable is communicated between the lamp assembly and the capstan by way of a central bore in a mast that supports the lamp assembly for rotation about a vertical axis.Type: GrantFiled: June 7, 1995Date of Patent: December 17, 1996Assignee: Federal Signal CorporationInventors: Earl W.
