Patent number: 8113226Abstract: Check valve assemblies and related methods are described. A valve assembly comprises a housing having at least a first inlet passage and an outlet passage. A flow channel is disposed within the housing, with at least a portion thereof extending inward from the first inlet passage. A first check member is disposed within the first inlet passage and is movable along the flow channel between a closed position in which the first check member is disposed against a first valve seat and an open position in which the first check member is spaced from the first valve seat. In varying examples, movement of the first check member from the closed position to the open position is unopposed. Optionally, the housing can include at least a second inlet passage wherein a second check member is disposed. In an example, the second check member is continuously biased toward a closed position.Type: GrantFiled: June 8, 2010Date of Patent: February 14, 2012Assignee: Restaurant Technologies, Inc.Inventor: Michael J. Zweber

Publication number: 20110238310Abstract: A method comprises operating one or more commercial fryers, including activating an operational event for the one or more commercial fryers by sending a current through a wire to an operational member of the commercial fryer, collecting information each time a different operational event is carried out in the commercial fryer by sensing whether the current is flowing through the wire or by sensing whether a voltage is present in the wire, and communicating the information to a database.Type: ApplicationFiled: September 29, 2010Publication date: September 29, 2011Applicant: RESTAURANT TECHNOLOGIES, INC.Inventors: ARIES ESTRELLADO, MICHAEL J.

Publication number: 20080042090Abstract: This patent document describes various valve assemblies comprising a valve member movable between an outlet flow-blocking and an outlet flow-passing position. A portion of a valve member first end is covered by a pilot, while a valve member second end is operatively associated with a solenoid mechanism. In an example, the solenoid mechanism is configured to initially move the valve member from the outlet flow-blocking to a bleed position, and subsequently move the valve member from the bleed position to the outlet flow-passing position. The pilot covers the valve member such that a solenoid mechanism force needed to move the valve member from the outlet flow-blocking position is reduced. For instance, the pilot reduces a surface area of the valve member subject to a housing outlet pressure.Type: ApplicationFiled: August 17, 2007Publication date: February 21, 2008Applicant: Restaurant Technologies, Inc.Inventor: Michael J.

Patent number: 6431794Abstract: A dock support bracket has a central clamp of general C shape having an internal channel and opposing first and second side arms. The bracket has a clamping screw and a first beam mounting base on the first side arm and has an abutment and a second beam mounting base on the second side arm. The second beam mounting base is angular to the second side arm and to the first beam mounting base. Dock section beams can be mounted on the respective mounting bases of the bracket to form a dock. A dock support post can be received within the channel of the clamp, and pressed by the clamping screw of the first side arm against slippage on the post. Docks formed using the bracket have minimal or no side projecting hardware.Type: GrantFiled: March 23, 2001Date of Patent: August 13, 2002Inventor: Michael J. Zweber

Patent number: 5899962Abstract: A two-wire transmitter senses differential pressure, absolute pressure, and process temperature of a process fluid. The information can be used to provide an output representative of mass flow through a pipe. The transmitter has an electronics module housing attached to a sensor module housing. The sensor module housing contains all the sensors for the pressures and includes a boss input for receiving a signal representative of a temperature or pressure signal. The three process variables are appropriately digitized, and received by an electronics circuit board in the electronics housing including a microprocessor for calculating the mass flow. The microprocessor in the electronics housing also calculates a compressibility factor and a discharge coefficients according to a polynomials of specific forms. The boss is integral to the sensor module housing and is adapted to fit either shielded twisted pair cabling or conduit.Type: GrantFiled: January 31, 1997Date of Patent: May 4, 1999Assignee: Rosemount Inc.Inventors: Bennett L.

Patent number: 5606513Abstract: A two-wire transmitter senses a pressure using an internal pressure sensor. The transmitter includes an input for receiving a process variable from a remote sensor which is separated from the transmitter. Circuitry in the transmitters transmits information on a two-wire process control loop which is related to the sensed pressure and the process variable.Type: GrantFiled: June 9, 1994Date of Patent: February 25, 1997Assignee: Rosemount Inc.Inventors: Bennett L. Louwagie, Gregory S. Munson, David E. Wiklund, Michael J. Zweber, David A. Broden, Brian J. Bischoff, Gary P. Corpron

Patent number: 5236202Abstract: A spring loaded seal is placed between three continuous groove walls between mating parts adjacent to a pressure transmitter isolator. The seal includes a resin ring with two ring walls conformable to two of the groove walls. A third ring wall has a continuous slot extending into the ring. A coil spring is placed in the slot such that, upon mating of the parts, the third wall presses the coil spring toward the slot. This compresses the coil spring to sealingly force the first and second outer ring walls against the first and second groove walls respectively with a controlled force. The coil spring's compression controls the sealing force to limit undesired distortion of the groove walls.Type: GrantFiled: September 23, 1991Date of Patent: August 17, 1993Assignee: Rosemount Inc.Inventors: Terrance F. Krouth, Michael J. Zweber
