Abstract: In household appliances with a safety hose, the stop valve and the control valve are hydraulically connected in series. It is thus impossible, or very difficult, for the user to detect when one of the valves is operating erroneously and not closing completely. The functioning of the control valve and of the stop valve is checked each time the household appliance is used. For this purpose, the valves and are alternately opened and closed in a selected phase during operation, or are opened and closed one after the other. The change over time in the measured values is recorded and evaluated in a suitable manner at a pressure sensor and/or at a throughflow meter. On account of the multiple use of the measuring sensors that are present, the cost of implementing the method is restricted to expanding the control system software.

Abstract: A leak collection chamber is provided inside the housing of a fuel dispenser. The leak collection chamber collects any leaked fuel from fuel handling components inside the fuel dispenser so that the fuel does not leak to the environment. The leak collection chamber can be removed from the fuel dispenser for evacuation. The control system inside the fuel dispenser can determine the liquid level inside the leak containment chamber and generate signals and alarms if the liquid level exceeds a threshold liquid level value and/or the rate of increase in liquid level exceeds a threshold liquid level increase value. The control system can alert service personnel and/or other systems of the leak collection chamber liquid level. Further, the control system and/or other systems shut down the submersible turbine pump that services the fuel dispenser with fuel in response to catastrophic leak condition.

Abstract: A plumbing tool includes an elongated hollow shaft and a resilient member attached to the shaft adjacent a shaft end. The resilient member extends radially outward and is sized to closely fit within a pipe inner diameter. Once the pipe has been cut, the tool is forced into the pipe end and the resilient member closely fits within the pipe inner diameter to block fluid flow. As the shaft is hollow, fluid flow is diverted through the shaft. A valve is then passed over the tool to engage the pipe end. As the fluid is being diverted through the tool, the value is then soldered to the pipe without concern for the heat sink effect of fluid passage through the pipe. Once the valve has been properly soldered to the pipe end, the tool is simply pulled through the valve and removed. Capping of the pipe end with the valve is therefore rapidly achieved with minimal disruption to the users.

Abstract: A method and apparatus for preventing leakage from a fitting coupling a first and second fluid supply line to an environment surrounding the fitting is generally provided. In one embodiment, a containment apparatus includes a body having a first, second and third aperture formed therethrough. The body defines interior volume that is adapted to substantially enclose the fitting. The interior volume is adapted to be maintained at a pressure less than the surrounding environment to prevent fluid that may leak from the fitting from being released into the surrounding environment. In another aspect of the invention, a method for preventing fluid leakage from a fitting coupling a first and second conduit from entering an environment surrounding the fitting includes enclosing the fitting in a volume defined between a first shell and a second shell, evacuating the volume, and drawing air into the volume from between the shells.

Abstract: In an electro-mechanical distribution system having plural units each comprising a valve/switch and dual sensors, a computer is associated with each unit so as to process sensor information and control the valve/switch. According to the control logic, a unit is either in normal mode or fault mode. The fault mode begins with a transient waiting period and may continue on to a series of steps. A step waiting period (wherein the valve is closed) may be followed by the step testing period (wherein the valve is closed) of the same step; a step testing period may be followed by the step waiting period of the next step. Fault mode is triggered if at any time during normal mode either sensor detects a fault condition. Normal mode is triggered if at any time during fault mode both sensors concurrently detect a normal condition.

Abstract: A computer system implements a process for gathering, synthesizing, and analyzing data relating to a pump and/or seal or other rotating equipment failure. Data indicating the current state of the equipment is gathered and verified prior to a failure occurring so that accurate information is available. After a failure or problem occurs, data about the problem or failure are methodically gathered to aid in the determination of the root cause of the failure. In particular, visual images of failure modes are provided to the user to ensure that proper and accurate data are obtained. A user also is directed to gather other data about the failure and the system. After data relating to the problem or failure has been gathered, the data are synthesized and an analysis is performed to determine the root cause of the failure or problem. These various methods and apparatus allow a non-specialist to properly identify and diagnose a failure or problem associated with a mechanical seal and pump.

Abstract: A spill containment system and method that contain leaks and spills from devices including but not limited to batteries.

Abstract: A system and method are disclosed for sealing leaks in electrical insulators and other equipment without the need for depressurizing that equipment. The system and method may be readily adapted to seal any joint, regardless of its configuration. In addition, while the system and method provide an effective and sure seal, the seal may be readily removed in order to change out the leaking component at a future date. A tubular seal is maneuvered into position to encircle the leaking joint. A reinforcing layer is applied over the seal. The seal is then filled with sealant under pressure. The seal isolates the sealant and its direct hydraulic pressure from the operating components to prevent the sealant from contacting those components, while simultaneously providing sufficient force against the leaking joint to stop the leak.

Abstract: A collector unit to be attached to a ceiling to collect leaking water and falling debris is formed by a sheet of water impervious material, preferably foldable and flexible, and having a generally concave shape with an outlet drain at a lower part. A net is fastened to the sheet across its open top. The unit is fastened to a ceiling and leaking water passes through the net, flows in the sheet to the outlet drain and it is conveyed away from the collector unit through a drain line connected to the outlet drain. Debris falling from the ceiling is caught by the net so that it does not reach the sheet and clog the outlet drain. The sheet and net are preferably of a material such that the collector unit can be folded into a package.
