Publication number: 20120305817Abstract: A flow regulator comprising a needle valve assembly secured in a molded valve body having offset mounting flanges to permit a variety of flow control and monitoring components to be secured thereto. The valve body has parallel inlet and outlet passageways connected by a transverse passageway, with a metal ring forming a valve seat molded into the valve body around the transverse passageway. A valve stem mounted within a valve stem receiver by a support member is selectively advanceable against and away from the valve seat to control flow therethrough. A lateral expander positioned in a slot in the valve stem is compressed axially upon rotation of the valve stem causing the expander to expand in the slot to secure the valve stem in place relative to the support member.Type: ApplicationFiled: June 6, 2011Publication date: December 6, 2012Applicant: BURGER & BROWN ENGINEERING, INC.Inventors: Philip M. Burger, Mark A. Brown, Jimmie L. Robinson

Patent number: 7729869Abstract: An electronic flow meter having sensors to determine the temperature and flow rate of a fluid flowing through the flow meter and into a downstream circuit, such as a cooling water circuit, of known diameter is flowing under turbulent or laminar conditions based upon a calculation of a corresponding Reynolds number and comparison of the calculated Reynolds number to Reynolds numbers indicative of the desired flow characteristic. A display is provided to indicate the flow characteristic of the fluid flowing through the flow meter as determined by the processor.Type: GrantFiled: November 16, 2007Date of Patent: June 1, 2010Assignee: Burger & Brown Engineering, Inc.Inventors: Mark A. Brown, Kendall D. Foos

Patent number: 7569783Abstract: A low profile limit switch utilizes a bowed spring actuator for advancing a bridge contact into and out of contact with a pair of terminal contacts to close and open the switch. The bridge contact is mounted on a glide on an end of the spring and formed from an insulating material. The terminal contacts are spring loaded and maintained in spaced apart and staggered relationship so that only one of the terminal contacts remains in contact with the bridge contact when it is retracted by the bowed spring. A mounting clip including a mounting flange and spaced apart spring loaded arms extending generally perpendicular to the mounting flange is used to mount the switch to a surface proximate an edge without having to obtain any significant amount of vertical clearance above the switch for bolting it to the surface.Type: GrantFiled: February 21, 2007Date of Patent: August 4, 2009Assignee: Burger & Brown Engineering, Inc.Inventors: Philip M. Burger, Paul Horner

Patent number: 7549348Abstract: A flow meter having a scale with temperature set points corresponding to a flow rate that a known fluid flowing therethrough at the set point temperature must reach to ensure turbulent flow of the fluid through a cooling system of a specified diameter. The flow meter preferably includes a plurality of scales, each having temperature set points corresponding to a different sized passageway in the mold cooling system. The scales are printed on a sleeve, rotatably mounted on a cylindrical body of the flow meter. The scales are selectively rotated into view by an operator to permit the operator to use the appropriate scale corresponding to the diameter of the passageways of the cooling system with which the flow meter is to be used.Type: GrantFiled: June 27, 2007Date of Patent: June 23, 2009Assignee: Burger & Brown Engineering, Inc.Inventors: Mark A.

Patent number: 6471503Abstract: A rotary disc valve is disclosed which generally includes a housing having an inlet side and an outlet side, and a disc rotatably mounted within the housing between the inlet side and the outlet side thereof. The disc includes an outlet bore which is generally aligned with the axis of rotation of the disc and extends from the outlet face of the disc partially through the disc. One or more inlet bores spaced radially outwardly from the axis of rotation of the disc extend from the inlet face of the disc partially through the disc and communicate with the outlet bore. The inlet bore or bores are located such that a bore may be selectively brought into communication with a single one of inlet side passages by rotating the disc until the bore is aligned with the desired passage. Since the outlet bore and an outlet passage are aligned along the center of rotation of the disc, the outlet bore stays in constant communication with the outlet passage in the outlet side of the housing as the disc is rotated.Type: GrantFiled: November 7, 2000Date of Patent: October 29, 2002Assignee: Burger & Brown Engineering, Inc.Inventors: Wayne A.
