Patent number: 6485175Abstract: A thermowell assembly (20) shown in FIG. 2 is positioned in a pipeline (10) for sensing the temperature of the fluid medium in the pipeline (10) for transmitting the sensed temperature to a meter (12). A temperature sensing probe is received within a temperature conducting tube (36) forming a thermowell and having a plurality of annular fins (40) extending thereabout. In the embodiments of FIGS. 1-7, a liquid (50) is provided in an annular space between the thermocouple (28) and the temperature conducting tube (36). Non-metallic members (70, 74, 80) are positioned between the pipeline (10) and the temperature transmitting tube (36) to isolate thermocouple (28) from ambient changes in the temperature of metal pipeline (10) which may result in an error in the temperature of the flow medium sensed by the thermowell assembly (20). High temperature embodiments shown in FIGS.Type: GrantFiled: April 11, 2000Date of Patent: November 26, 2002Assignee: PGI International, Ltd.Inventors: Spencer M. Nimberger, Kevin J. Cessac

Patent number: 6422162Abstract: The present invention provides an apparatus and method for accurately controlling the amount of NH3 to be applied to a field by measuring the NH3 flow rate without condensing or cooling the NH3. The system includes a control station 12 on the vehicle with a tachometer 12A or a GPS system for providing a vehicle speed signal to a control panel 13. The control panel includes a toggle switch 17 for adjusting the opening or closing of a valve 52 in the flow line to regulate the flow through the system, although the control panel alternatively may automatically control the valve 52. The vehicle transports a tank 20 containing liquid NH3 and a tool bar 30 for distributing the NH3 to the soil. After flowing through the flow meter 40, 60, 130, the NH3 is conducted to the soil through a series of hoses, fittings, a distributor, and tubing. The flow meter transmits a signal to the control panel, which is converted to a corrected flow rate signal in response to a fixed value vaporization correction factor.Type: GrantFiled: May 24, 2000Date of Patent: July 23, 2002Assignee: PCI International, Ltd.Inventors: Spencer M.

Patent number: 6308753Abstract: A system for transferring a hazardous fluid product from a transport tank (10) of a roadway vehicle (12) to a fixed storage tank (14). A flexible transfer hose assembly (30) has end couplings (34, 36) which are detachably connected between the transport tank (10) and storage tank (14). A gas operated product supply valve (44) is opened by pressurized gas to permit flow of the hazardous product, such as propane, from tank (10). A gas control valve (46) controls the flow of pressurized gas to gas operated product supply valve (44). Upon a separation or rupture of flexible hose (31) or couplings (34, 36), the fluid pressure of the hazardous product in hose (31) is sensed at fluid sensing chamber (94) in gas control valve (46). A reduction in sensed fluid pressure to a predetermined maximum pressure results in movement of piston (82) to the position shown in FIG.Type: GrantFiled: March 4, 2000Date of Patent: October 30, 2001Assignee: PGI International, Ltd.Inventors: Spencer M.

Patent number: 6289752Abstract: A system for a sampling hydrocarbon containing gas flowing in a pipeline by collecting a fluid sample in a sampler bottle 55 includes a sample probe 12 secured to and extending outward from the pipeline, a heater body 20 removably secured to the probe, and vortex heater 34 for outputting a cold fluid and hot fluid. The heater body 20 has flow path therein for directing the hot fluid to heat the sample probe, and preferably thereafter heat the bottle 55. The pressurized gas to the vortex heater may be supplied directly from the pipeline P, with pressure control by a regulator 24. Alternatively, pressurized gas such as air may be stored in a portable vessel 172 for supplying compressed air to the vortex heater 34. An improved method of sampling gas in a pipeline using the vortex heater is disclosed.Type: GrantFiled: July 18, 2000Date of Patent: September 18, 2001Assignee: Pgi International, Ltd.Inventors: Spencer M.

Patent number: 6176262Abstract: Different functional control manifolds, adapted for specific process and test applications, are selectively mounted on a common base manifold which independently provides sealing of the process lines of a fluid handling system. This enables a specific functional control manifold such as a single block and controlled vent manifold, a single block and vent manifold, or a double block and bleed cross-over manifold, to be preassembled with a test instrument prior to installation of the test instrument to the base manifold. Each embodiment of the functional control manifold is designed so that the sensing cavities of the test instrument are able to fully drain through the functional control manifold into the base manifold, thereby eliminating a potential source of error during calibration of the test instrument.Type: GrantFiled: September 13, 1999Date of Patent: January 23, 2001Inventor: Spencer M. Nimberger
