| 101 | Safety valve for compressed gas cylinders | US800046 | 1991-11-29 | US5144973A | 1992-09-08 | J. Kenneth Green; Eugene L. Watson; Paul S. Whalen |
| A safety valve for fitting into a compressed gas cylinder to terminate gas flow from the cylinder when a primary gas valve attached to the cylinder port of the cylinder is deflected or severed. The safety valve is independently supported in the cylinder port below the location of the primary gas valve. A threaded housing having a channel for the passage of gas to and from the cylinder is threaded into the cylinder port below the location of the primary gas valve. A poppet seat is provided in the housing. A tubular portion of the threaded housing extends up and fits snugly into the gas passage of the primary gas valve. A cylindrical housing having apertures for the passage of gas is attached to the threaded housing. A poppet is provided in the cylindrical housing, which is biased into the poppet seat by a helical spring. The poppet is held off of the poppet seat by means of a frangible element. A relatively minor deflection, or shearing off, of the primary gas valve will be passed through to the frangible element, resulting in the breaking of the element and thereby allowing the poppet to seat in the poppet seat preventing the flow of gas from the cylinder to the primary gas valve. A polymer collar may be used in connection with the safety valve to eliminate thread leakage. A remote triggering device is set forth for seating the poppet in the poppet seat without a deflection or severing of the primary gas valve. Further, a flow restriction device for use with the safety valve is described. | ||||||
| 102 | Process for monitoring the leaktightness of a storage facility | US66669 | 1987-06-26 | US4805445A | 1989-02-21 | Jacques Grappe |
| A storage device has an inner enclosure (6) and a leakproof and a rigid outer enclosure (5), which are mounted one inside the other and separated by an intermediate space (9) containing a fluid, continuous in phase at pressures other than that of the material stored, and pressure measurement equipment (16, 15) enabling the differences in the pressure of the fluid to be monitored. Advantageously, the device additionally features sampling equipment (18, 17) enabling the composition of the fluid to be monitored. The device may be buried, the outer enclosure being then placed against the cement walls (4) of a cavity, which may be a drilled well. The inner enclosure may feature a leakproof skin which is made rigid by the presence in the intermediate space of a porous and rigid filling material in which the fluid can circulate. | ||||||
| 103 | Method and apparatus for underground storage of ammonia and analogous products | US604289 | 1984-03-26 | US4542626A | 1985-09-24 | Pierre Colin |
| When a product such as ammonia, which is liquefiable under pressure and which is miscible with water is stored underground the storage takes place at the liquefaction pressure of the product and inside a double skin which defines an intermediate space (10), with both skins being inserted in a cavity (1) formed in a water-impregnated formation. The depth of the storage is so chosen that the hydrostatic pressure of the water in the formation is greater than the greatest expected pressure of the stored product, with the intermediate space being filled with water and being maintained at a pressure which is lower than the lowest expected pressure of the stored product. If the inner skin is punctured, NH.sub.3 is recovered in the water in the shaft (2) and does not escape to contaminate the water in the surrounding formation. | ||||||
| 104 | Automatic valve shut-off system | US578085 | 1984-02-08 | US4527715A | 1985-07-09 | Leonard A. Rosenbaum |
| An automatic valve shut-off system useful for gas cylinders and the like employing a pneumatically actuated rotatable shaft to engage the valve handle on the cylinder. A control box is located remotely and conduits carry pressurized gas to energize the pneumatic activator. Solenoid or manual type operated switches select the delivery of pressurized gas to the cylinder and a pneumatic feed back device is provided to indicate the position of the valve handle. | ||||||
| 105 | Fill valve responsive to liquid level | US493259 | 1983-05-10 | US4522227A | 1985-06-11 | Gerald D. Mylander |
| The fill valve is responsive to liquid level by passing vented vapor through serial orifices. The inlet flow is stopped by shifting a valve spool which is responsive to the pressure between the orifices. A pressure booster adjacent the vent outlet serves to momentarily shut off the outlet when pressure rises in the region of the second orifice to aid in shifting the main valve spool when system pressure is low. | ||||||
| 106 | Apparatus for leakage detection of cryogenic materials | US571146 | 1984-01-17 | US4501124A | 1985-02-26 | Edward B. Shone; Robert W. Wilson; Gordon L. Cunningham |
| A device for detecting leaks of cryogenic materials from a structure, said device comprising a heat-conductive element which can be brought into contact with the cryogenic material-containing structure, and a shape memory effect element capable of effecting a displacement according to the cryogenic temperature to which the element is subjected. | ||||||
| 107 | Remote relief-vent device | US353805 | 1982-03-01 | US4471812A | 1984-09-18 | Paul Bertsch |
| A relief-vent device to be employed in combination with pressure-release valves associated with high-pressure gas-storage tanks, such as LPG storage tanks that are mounted to vehicles for which such gas is employed as a means for fuel. The vent device is normally required to be located remotely from the storage tank, and to be mounted for vertical discharge or at an angle not exceeding 45.degree. thereto, the vent body being formed having an annular recess to receive a flexible vent cover that is secured along one edge thereof within the recess, whereby the outlet formed in the body is closed so as to be sealed until gas is released from the tank for discharge to the atmosphere. | ||||||
| 108 | Protective system for use in transfer of hazardous substances | US231582 | 1981-02-04 | US4354571A | 1982-10-19 | John Lakin; Philip R. Watson |
| A safety and control system for the product outlet valves of a vehicle tank has pneumatically operated valves associated with each product outlet of the tank, control valves are connected to an air reservoir through a charge valve for effecting operation of the outlet valves, the charge valve being of a single shot type for pressurizing a manifold connected to the product outlet valve or valves. The manifold is connected with emergency release valves and a further solenoid operated valve is operatively connected with a gas detector means. With this arrangement either on detection of escaping product vapor by the gas detector or actuation of the emergency release valves pressure in the manifold is vented thereby closing the product outlet valves through release of pressure, the control valves thereafter being inoperative until the charge valve is actuated to re-pressurize the manifold.A system for protecting and also shutting down the vehicle engine is also disclosed. | ||||||
| 109 | System gas alarm | US102022 | 1979-12-10 | US4275681A | 1981-06-30 | Soman Ragavan; George Spector |
| An audible alarm activated by a conventional safety valve of a domestic gas cylinder, so as to warn residents of gas being discharged into the atmosphere and contaminating the same; the alarm including a plug on a chamber into which the gas is discharged so that the plug is pushed outward and pull therewith a trigger arm away from a spring wound, toothed gear along whose edge a pivoted lever is bounced up and down so a hammerhead on the lever end strikes a bell. | ||||||
| 110 | Single stage regulator with surge reducing valve | US33760 | 1979-04-27 | US4263939A | 1981-04-28 | Robert E. Bird |
| In a single stage regulator as used in conjunction with a high pressure vessel, a surge reducing valve is positioned within the outlet from the regulator and just at its low pressure side of the regulator in order to reduce any surge or jump in the gas flow during sustained gas consumption or when it is shut off. | ||||||
| 111 | Safety liquid dispenser | US780801 | 1977-03-24 | US4177863A | 1979-12-11 | Sydney Simon |
| An improved inflammable liquid safety tank comprising a double walled tank body with the tank walls being interconnected by support plates. An intermediate container is formed by the inner wall structure of the tank and is adapted to hold inflammable liquid. A pressurized gas bottle is threadably mounted to a sleeve secured to and extending into the intermediate container. The pressurized gas bottle is selectively connected to the intermediate container to pressurize liquid held in the intermediate container. The pressurized gas bottle also communicates with the tank to pressurize a foam, nonflammable fluid, or cleaning agent placed in the chamber or outer compartment defined by the outer wall structure of the intermediate container and the inner wall structure of the tank body so that the foam, fluid or agent will be expelled from the tank if the tank wall is accidentally punctured. The outer compartment is preferably pressurized at a lower pressure than the intermediate container. A conduit is connected to an inlet/discharge fitting and extends into the intermediate container adjacent the floor of the intermediate container and below the level of liquid placed in the intermediate container. A flexible hose with an adjustable nozzle is mounted to the tank body for selective communication with either the outer compartment or the intermediate container so that the material contained within either of the containers can be selectively discharged from the nozzle. | ||||||
| 112 | Pressure container with an injection valve provided with a fusible valve member | US414502 | 1973-11-09 | US4059125A | 1977-11-22 | Nobuyuki Sugimura; Kazuo Sugimura |
| A novel structure of pressure container is disclosed, wherein a safety valve is provided within an air injection valve of said pressure container, whereby even when the ambient atmosphere of said accumulator has been heated up to a high temperature because of a fire and the like, bursting of said pressure container may be prevented. A valve seat is formed inside of a valve casing and a fusible valve member is brought in contact with said valve seat, so that when the ambient temperature of said pressure container has been raised said fusible valve member may fuse to permit the gas pressure in the pressure container to be discharged to the exterior of the container. Said fusible valve member is filled within a hollow space of a cylindrical valve stem and said valve stem is provided with a passageway or passageways communicating with the interior and exterior thereof, so that when the fusible valve has been fused, the gas within the gas pressure container may blow away the fusible member in a fused state through said passageway or passageways to the exterior of the container. | ||||||
| 113 | Safety connector for pressure tank | US628377 | 1975-11-03 | US4033369A | 1977-07-05 | Russell D. Keller |
| A pressure tank connector is described which is formed integral with the cylindrical side wall portion of the tank so that such connector deforms and acts as a safety valve when the fluid pressure within the tank exceeds a predetermined pressure. The deformed connector produces a space between it and an insert member which enables the pressurized liquid or gas within the tank to slowly leak out through such space. In the preferred embodiment, the connector includes a threaded cylindrical connector portion joined by a conical projection portion to the side wall of the tank. The fluid escapes from the tank through a space formed between the threads of such connector and those of an external fitting screwed into such connector. | ||||||
| 114 | Method and apparatus for controlling a volatile substance | US387461 | 1973-08-10 | US3981701A | 1976-09-21 | Harold Willids Andersen; Charles H. Harrison |
| In controlling a volatile substance, for example in controlling the release of ethylene oxide for use in a sterilization apparatus, the volatile substance is contained under pressure in a confined system and the latter is immersed in a fluid. The fluid is capable of absorbing the volatile substance such that if any of the volatile substance leaks from the confined systems into the immersion fluid, physicochemical changes will occur in the immersion fluid. These physicochemical changes may be sensed by various detecting devices which thereby serve to detect leaks of volatile substance from the confined system. The immersion fluid may be used as a heat transfer medium in heat exchange relationship with the confined system and desired associated control elements such as a pressure regulator to thereby prevent undesirable condensation of the volatile substance. | ||||||
| 115 | Gas detection system | US49245874 | 1974-07-29 | US3925666A | 1975-12-09 | ALLAN COLIN J; BAYLY JOHN G |
| The gas detection system provides for the effective detection of gas leaks over a large area. It includes a laser which has a laser line corresponding to an absorption line of the gas to be detected. In the instant case, a He-Xe laser scans a number of retroreflectors which are strategically located around a D2O plant to detect H2S leaks. The reflected beam is focussed by a telescope, filtered, and passed into an infra-red detector. The laser may be made to emit two frequencies, one of which corresponds with an H2S absorption line; or it may be modulated on and off the H2S absorption line. The relative amplitude of the absorbed light will be a measure of the H2S present.

| 116 | Expansive gas protective device | US24253372 | 1972-04-10 | US3817299A | 1974-06-18 | KOEHLER C |
| An expansive gas protective device for use in a personnel work area and including a heavy walled protective vessel formed with a high pressure work piece chamber disposed in the work area and formed with a discharge outlet opening to an area remote from such work area and a doorway opening into such work area and normally covered by a heavy door. A high pressure source includes connector means disposed within the chamber for connection with work pieces located in such chamber. Means is also provided for moving the door between open and closed positions. Thus, work pieces may be placed in such chamber and the connectors connected therewith, the door closed and the high pressure source actuated to pressurize the work pieces. In the event of a failure and rapid expansion of gases in such chamber, the expanding gases will be directed out such outlet to the area remote from the work area and, likewise, any debris or airborne work pieces will also be directed away from the work area to protect personnel working in such area.

| 117 | Anaesthetic supply | US3779414D | 1972-05-10 | US3779414A | 1973-12-18 | JONES W |
| The specification discloses the combination of a bottle and a connecting cap therefor, both components having mating screw threads, the components having a mating key and keyway system extending axially of the bottle neck and being designed so that mating of the key and keyway system is necessary before relative rotation between the cap and the bottle to screw the cap onto the bottle is possible. Thus, a connecting cap can only be secured to a bottle if the bottle and cap are complementary and the potential danger of connecting a bottle containing the wrong liquid to, for example, an anaesthetic vapouriser, can be avoided.
