Abstract: A safety device for a cylinder holding gaseous fluids under pressure is disclosed. The safety device has a device body in which a passage is defined for a fluid; the passage extends from an entry aperture, suitable for being placed in fluidic communication with a cylinder, to an exit aperture. An obturator air tightly engages the passage, the obturator is movable from a first position, in which it indicates the presence of fluid at a pressure below a first predefined pressure threshold value, inside the cylinder, and a second position, in which it indicates the presence of fluid at a pressure above the first predefined pressure threshold value inside the cylinder. At least one temperature and/or pressure-sensitive relief device is positioned in the obturator in such a way that, upon exceeding a predefined temperature threshold or upon exceeding a second predefined pressure threshold, the relief device opens the passage for the fluid and permits the flow of fluid from the entry aperture towards the exit aperture.

Abstract: A stress reactive valve includes a valve body disposed in a subsea safety system or other elongated components of hydrocarbon production systems. The valve body includes a frangible or breakable material such that when the subsea safety system or other elongated system undergoes a stress, such as a bending stress, the frangible valve body can react to the stress by breaking and thereby establishing fluid communication or a fluid path across the valve body. In a first or unbroken condition of the valve body, the valve body prevents fluid communication between a fluid inlet and a fluid outlet. In a second or broken condition of the valve body, fluid communication is allowed between the fluid inlet and outlet. The fluid communication can be used to actuate a device, or the fluid pressure can be used as pilot pressure to actuate a pilot operated valve system.

Abstract: A modular hydraulic hammer reduction system for railroad tank cars includes tubular hydraulic hammer reduction devices which include means to connect the tubular devices to flanges other than by welding or being cast together. For example, the tubular devices can be press fit into the flanges, or the tubular devices can be connected to the flanges with snap rings (preferably spiral-lock snap rings), or even more preferably the tubular devices can be press fit into the flanges and the tubular devices can be connected to the flanges with snap rings (preferably spiral-lock snap rings). The advantage of this modular construction is that one can manufacture multiple tubular devices and multiple flanges of each type, and connect the flanges to the tubular devices on an as-needed basis. This is preferable to having many of each type of hydraulic hammer reduction system assembled and ready to be delivered, as the demand for different types of hydraulic hammer reduction systems varies and storing fully assembled devices will take up more space.

Abstract: A flame front diverter element is designed to cause a minimal pressure drop under normal venting conditions when process vapors need to pass through the explosion protection system and to other equipment connected to the manifold system. In the event of a deflagration, the flame front diverter directs the high-speed pressure wave towards a bi-directional rupturable disc causing the rupturable disc to open thus creating an aspiration effect on the opposite bi-directional rupturable disc.

Abstract: A system for the control of an indirectly heated gas turbine comprising a primary system of controlling the temperature of heated compressed gas entering the expander, and an independent secondary system which includes a safety valve for instantaneous release of heated compressed gas to the atmosphere. The primary system controls system gas temperature and power output by modulating a flow of unheated compressed gas which bypasses the heat exchanger and mixes with the heated gas leaving the heat exchanger to produce a lower temperature gas entering the expander. The secondary system provides a backup means of overspeed prevention, and includes a safety valve to instantly discharge to the atmosphere hot compressed gas upstream of the expander by being responsive to the speed of the turbine. The safety valve includes a frangible membrane clamped between parallel flanges within the ducting, and further includes a dagger assembly for rupturing the membrane.
