| 163 | Thermal management smart valve with rupture detection and isolation | US13021580 | 2011-02-04 | US08600566B1 | 2013-12-03 | Donald R. Longo; Donald D. Dalessandro; Qing Dong; Frank T. Ferrese; John M. Roach; Michael G. Zink |
| The condition of a fluid piping system is monitored by multiple intercommunicative smart valves, each executing a computer algorithm that designates smart valves as critical or non-critical, compares measurement data versus simulation data, and makes decisions based on the critical-or-noncritical designations and the measurement-versus-simulation comparisons. Initial measurement-versus-simulation comparisons are made for downstream pressure, flow rate, and temperature. If a measurement-versus-simulation discrepancy is found in either the downstream pressure or the flow rate, then the algorithm compares a measurement rupture determinant versus a simulation rupture determinant; if a measurement-versus-simulation discrepancy is found in the rupture determinant, then the smart valve is closed. If a measurement-versus-simulation discrepancy is found in the temperature, then the smart valve, if non-critical, is closed; however, if the smart valve is critical, then the nearest upstream non-critical smart valve is closed. Any measurement-versus-simulation discrepancy results, at least, in an alarm or warning. | ||||||

| 170 | Shut-off valve testing system | US13585405 | 2012-08-14 | US08413486B1 | 2013-04-09 | Tareq Nasser Al-Buaijan |
| The shut-off valve testing system provides for the testing of the main shut-off valve of a combustible gas supply line in such facilities as refineries, factories, or other plants utilizing such gaseous fuel. The system includes a combination hydraulic-pneumatic cylinder receiving pneumatic pressure from a suitable source, the cylinder communicating hydraulically with a hydraulic actuator for the main shut-off valve. The system provides for testing of the shut-off valve by actuating the valve through a portion of its full travel, thus confirming that the valve is free. This is accomplished by shutting off the pneumatic pressure to one side of the hydraulic-pneumatic cylinder, and opening the hydraulic line between the cylinder and the actuator. Thus, hydraulic pressure from the actuator can bleed to the cylinder, allowing the actuator to move to the extent of the limiting spring and/or pneumatic pressure to the opposite side of the cylinder. | ||||||

| 172 | GAS SHUTOFF DEVICE | US13701438 | 2011-05-31 | US20130081707A1 | 2013-04-04 | Takanori Kamimura; Mitsuo Yokohata |
| A gas shutoff device of the present invention is configured such that a control section determines that it inhibits a shutoff section from being returned from a shutoff state to a supply state, when a vibration has been detected by a vibration detecting section and a fluid pressure measured by a pressure measuring section has decreased to a value equal to or less than a predetermined pressure value. For example, the control section causes the shutoff section to switch to the shutoff state and disenables the return section to return the shutoff section to the supply state, when one of the vibration and the fluid pressure decrease has been detected and then the other has been detected within a predetermined time. | ||||||

| 178 | Valves Controlling Flow | US12083631 | 2006-10-24 | US20100140518A1 | 2010-06-10 | David Robert Billings |
| Valves controlling flow of gas or liquid, where compressible material is trapped within a rigid housing to provide a leak-proof seal surrounding an longitudinally movable rigid shaft. Where the shaft has a hollow channel and perpendicular ports to the outer surface, it allows for on and off control and is called a hollow shaft valve. If the shaft has diametric reductions on its outer surface, the valve allows for variable control. Creating a series of hollow shaft valves and variable shaft valves on a single shaft allows multiple functions through a single seal to create a serial shaft valve. The technology also allows for the precise and indexed variable control of fluid flow through a variable shaft valve by having a bayonet style system to precisely actuate orifice size rather than a rotary handle. This arrangement has application in a wide variety of situations including chlorination valves. In the case of automobiles, the valve used to vent fuel in the case of an accident can be triggered by mechanical means, such as an airbag deployment sensor system. | ||||||

| 180 | METHOD FOR CONTROLLING THE LEVEL OF A MOTOR VEHICLE BODY | US12441411 | 2007-07-13 | US20090266152A1 | 2009-10-29 | Dierk Hein |
| Disclosed is a method for diagnosing the function of a level control system (1) of a motor vehicle, comprising at least one valve (2a, 2b, 14, 26) and a control unit (10). An exchange of pressure medium from one side of the valve to the other side of the valve is possible when the valve is open, and an exchange of pressure medium is prevented when the valve is closed. The valve carries out a change of state, a variable (4, I) influencing the valve output is measured during the change of state, the measured variable influencing the output of the valve is compared with a reference curve, a family of characteristics or a limit value in the control unit (10), and based on the comparison in the control unit (10) it can be established if the valve has carried out the change of state. | ||||||
