Abstract: A disposable plug for installation in a cylindrical water line to temporarily block the water line to the passage of water therethrough. The disposable plug includes a cylindrically shaped tablet having a diameter substantially equal to the diameter of the water line so that when installed within the water line, water is prevented from passing the disposable plug. The cylindrically shaped tablet is characterized as being at least partially dissolvable when contacted with water. A water impermeable membrane surrounds at least a portion of the cylindrically shaped tablet to selectively prevent water from contacting it as long as the disposable plug acts to temporarily block the water line. The water impermeable membrane can be selectively disrupted allowing water to contact the cylindrically shaped tablet to selectively remove the disposable plug when no longer needed.

Abstract: A method and apparatus for preventing over-pressurization of vessel during filling with a fluid where temperature of the vessel would cause the fluid to flash or rapidly expand on contact. A shut off device is placed in a conduit between the fluid source and the vessel being filled, the shut off device including a flow control piston that is held in position to permit fluid flow. Fluid pressure from the displacement space in the vessel is provided on both end of the piston. When a condition of over-pressurization occurs in the vessel a rupture disc associated with one end of the piston fails and causes a depressurization on that end of the piston causing it to move to a position where further filling of the vessel is prevented. The piston is positioned by a buckling pin and can be reset after over-pressurization of the vessel is connected and filling can resume.

Abstract: An apparatus (24) for inflating an inflatable vehicle occupant protection device (22) comprises a container (40) which provides a source of inflation fluid. The container (40) has an opening (44) through which the fluid can flow to inflate the protection device (22). A support surface (84) is located adjacent the opening (44). A cavity (120) is located adjacent the support surface. A rupturable closure (100) extends across the opening (44) to block the flow of fluid through the opening. A weld (108) forms a fluid seal between the closure (100) and the support surface (84). A member (140) is located in the cavity (120) and has a first portion (144) engaging a surface defining the cavity to secure the member to the container (40). A second portion (142) of the member (140) engages the closure (100) to hold the closure against the support surface (84) of the container (40). The member (140) has an opening (146) through which fluid can flow when the closure (100) is ruptured. An actuatable igniter (160), upon actuation, ruptures the closure (100).

Abstract: A pressure sensor assembly includes a disk entirely of metal and having a plurality of circumferentially spaced petals, separated by a plurality of radially extending slots. The slots extend from the periphery of the disk to a position near the center. However, the disks are in electrical communication with one another. A pair of wire leads are respectively placed at terminals on two separate spaced-apart disks with the opposite end portion of the leads connected to an alarm monitor. The disk body can be used in low or high temperature applications and is corrosion resistant and preferably entirely metallic (for example, stainless steel). The disk body is designed to be installed between standard pipe flanges, between a flange and a rupture disk holder, or in a holder that is used as, or located downstream of, a rupture disk or similar device. The device is designed to cause a discontinuity (open circuit) in an electrical circuit as a result of fluid flow through the pipe. When a rupture disk or similar device bursts or a valve leaks, the resulting pressure charge will rupture (tear) the subject burst sensor creating an open circuit. The device may be of any metal with electrical conductivity compatible with an alarm system that is commercially available. The device may be domed and self-supporting. The all-metal sensor, and nonmetallic gasket provide an assembly that is more rugged, reliable, and economical than current designs and is reliable over a large range of temperatures. The apparatus of the present invention is nonfragmenting, which permits use under valves and applications where fragmentation presents a problem.

Abstract: A rupturable fluid flow indicator and a rupture disk assembly including the indicator are provided. The indicator is comprised of a rupturable member adapted to be clamped across a fluid flow passageway having at least one opening formed therein for weakening a portion of the member. An electric current conductor adapted to be electrically connected in an alarm circuit is attached across the weakened portion of the rupturable member whereby when the member ruptures as a result of fluid pressure exerted thereon, the conductor also ruptures.

Abstract: The present invention provides apparatus for visually indicating the failure of a rupture disc comprised of an elongated hollow body member, a piston disposed in the body member which is moved therein by pressurized fluid pressure exerted thereon, and an elongated indicator pin which is pushed by the piston through an opening in the body when pressurized fluid causes the piston to be moved therein. The body member includes a pressurized fluid exhaust port which is opened by the movement of the piston. Pressurized fluid exhausted through the exhaust port can be vented to prevent abnormal rupture disk operation or it can be utilized to activate an alarm.

A minimum number of bolts, preferably a maximum of three Jack-type bolts, secure the two flanges together to provide a quick access to the rupture disc insert type holder disposed between the flanges for replacement or inspection of the rupture disc contained within the insert type holder, where the Jack-type bolts spread the two flanges apart. Stop pins are provided on at least one of the flanges to position the insert type holder between the two flanges. Preferably, one of the flanges is slotted, and the other flange has threaded openings therethrough to receive the Jack-type bolts to provide for a quick release spreading of the flanges apart, each Jack-type bolt being provided with a positioning collar thereon.

Abstract: Frangible valve means within a flexible tube. The valve means comprises a tubular portion having closed ends, and an elongated, generally rigid member carried on the exterior of the closed end and positioned within the flexible tube. Frangible means are provided to permit the opening of the tubular portion adjacent the closed end by rupture of an area of weakness by manual manipulation of the elongated member from outside of the flexible tube. In accordance with this invention, the flexible tube defines an inner end flange, while the tubular end portion of the valve means defines, at its end opposite to the closed end, a retention flange. The retention flange includes a cylindrical wall positioned generally coaxially to the tube and surrounding the periphery of the inner end flange. The cylindrical wall, in turn, carries an annular closure flange enclosing and retaining the inner end flange. A method of assembling the above structure is also disclosed.
