Abstract: The shut-off valve testing system provides for the testing of the main shut-off valve of a combustible gas supply line in such facilities as refineries, factories, or other plants utilizing such gaseous fuel. The system includes a combination hydraulic-pneumatic cylinder receiving pneumatic pressure from a suitable source, the cylinder communicating hydraulically with a hydraulic actuator for the main shut-off valve. The system provides for testing of the shut-off valve by actuating the valve through a portion of its full travel, thus confirming that the valve is free. This is accomplished by shutting off the pneumatic pressure to one side of the hydraulic-pneumatic cylinder, and opening the hydraulic line between the cylinder and the actuator. Thus, hydraulic pressure from the actuator can bleed to the cylinder, allowing the actuator to move to the extent of the limiting spring and/or pneumatic pressure to the opposite side of the cylinder.

Abstract: Flow cytometry concepts are modified to enable dynamic characterizations of particles to be obtained using optical scattering data. Particles in flow will be introduced into a sample volume. Light scattered by a particle in the sample volume is collected and analyzed. What differentiates the concepts disclosed herein from conventional flow cytometry is the use of an acoustic source that is disposed to direct acoustic energy into the sample volume. As the particle passes through the sample volume, it responds to the acoustic energy, causing changes in the light scattered by the particle. Those changes, which arc not measured during conventional flow cytometry, can be analyzed to determine additional physical properties of the particle.

Abstract: An apparatus for pressure-testing a tubular body may be installed in the tubular-body interior. The apparatus comprises an activation-device seat, one or more bypass ports, a J-slot with an indexing pin and a spring. When an activation device, for example a ball, lands in the activation-device seat, fluid communication through the tubular body is blocked, allowing pressurization. During pressurization, the activation-device seat moves downward, causing the spring to compress and the indexing pin in the J-slot to move to the bottom position. Upon depressurization after the test, the activation-device seat moves upward, causing to spring to decompress and the indexing pin the J-slot to move to the top position. Upward movement of the activation-device seat unblocks the bypass ports, thereby reestablishing fluid communication through the tubular body. The tubular body may be drillpipe, casing or coiled tubing that is installed in the borehole of a subterranean well.
