摘要： A reverse-acting rupture disc (10) having a laser-defined reversal initiation feature (16) is provided in the bulged section (12) of the disc. The reversal initiation feature comprises at least a first lased area (22) that has a reduced thickness relative to rest of the bulged section. A second lased area (24) may also be provided within the margins of the first lased area. The second lased area has a depth that is greater than the depth of the first lased area. A line of weakness (40) may be formed in the bulged section that functions to direct reversal of the bulged section toward a particular area of the disc.

摘要： A valve for controlling flow of pressurized fluid from a confined area that is operable to relieve an overpressure condition as well as to allow flow of fluid in response to a pressure relief command. The valve including a valve body with a fluid passage therethrough, a reverse buckling rupture disc in the valve body in normally blocking relationship to the flow of fluid through the passage, and a selectively actuatable device carried by the valve body adjacent the convex surface. The actuatable device is operable to disrupt, without puncturing, the disc so as to initiate reversal and rupture of the disc and to permit flow of the pressurized fluid through the passage.

摘要： A rapid-closure gate valve (10) comprising pressurized gas reservoirs (37, 39) that are integrated with the valve body (12). Pressurized gas stored in the reservoirs (37, 39) is utilized to shift a gate member (20) from a valve open position to a valve closed position upon actuation of the valve. Actuation of the valve is achieved by an actuator assembly (14) coupled with the valve body. The actuator assembly is configured to initiate a flow of pressurized gas from the reservoirs into a chamber (48) which effects shifting of the gate member.

摘要： A burst indicator (24) for use in a rupture disc assembly (12) is provided. The burst indicator (24) comprises a non-electrically conductive material having an outer annular portion (66) and an inner section (68) joined to the outer portion by a pair of bridge features (70, 72). A circuit comprising electrically conductive segments (78, 80) is located on the burst indicator (24) and can be used to monitor the integrity of the rupture disc (20). One electrically conductive segment (78) is located on the outer annular portion (66), and another electrically conductive segment (80) extends across the bridge features (70, 72) and inner section (68). Upon rupture of the rupture disc (20), one of the bridge features (72) carrying an electrically conductive segment (80) severs thereby opening the circuit.

摘要： An oil well completion tool having a tubular assembly defining an elongated main passage is adapted to be connected to a multiple-section tubing string within an oil well casing. A severable plug is mounted in the tubular assembly in normal blocking relationship to the passage. A movable shear cylinder unit has a plug-severing edge operable to sever an entire central segment of the plug from a remaining peripheral portion thereof. Separate hinge structure has an elongated U-shaped leg portion connected to the central segment of the plug. The leg portion of the hinge structure, which undergoes elongation, is operable to retain the severed central segment of the plug in the main passage while allowing the central segment of the plug to bodily shift independent of and in a direction away from the peripheral portion of the plug. The severed central segment is received in a recess therefor in the tubular assembly wall structure in order to prevent interference of the severed central plug segment with the main passage.

摘要： A one piece flexible sanitary seal 16 of uniform cross-section is provided for over pressure vent structure that protects a confined space meeting hygienic standards. The seal 16 has an elongated body 38 provided with a central section 40, a C-shaped terminal end 42 having a main lug portion 46 and a secondary lug segment 48 that project away from each other with a cavity 50 therebetween, and a long tail portion 44 cooperating with the central section 40 to present a longitudinally extending angular groove 62. The seal 16 is adapted to be mounted between a vent membrane unit 14 and a frame component 18 of the vent structure. Lug portion 46 and lug segment 48 sealingly engage the inner surface of the vent membrane 14 inboard of a line of weakness therein defined by a series of slots. A rectangular projection 52 extends from the central section 40 in disposition to engage the vent membrane unit 14, outboard of the line of weakness. The main lug portion 46 and the secondary lug segment 48 of terminal end 42 are moveable toward and away from one another while remaining in tight sealing engagement with the vent membrane unit 14 during in and out cycling thereof. Frame component 18 is received in the groove 62 to firmly affix the seal 16 to the vent structure.

摘要： A reverse acting rupture disc is provided having a laser defined electropolished line-of-weakness recess, and an improved method of forming an electropolished line-of-weakness recess in a reverse acting rupture disc that assures hll opening of the disc upon reversal. A rupture disc blank is pre-bulged, final bulged, and then provided with a layer of resist material. A laser is used to remove at least a portion of the layer of resist material corresponding to a desired line-of-weakness recess in the concave face of the bulged rupture disc. The disc Is then subjected to an electropolishing operation to remove metal from the lased area of the rupture disc, thereby forming a lustrous polished line-of-weakness recess In the disc of desired configuration and of a predetermined depth that is related to material thickness.
