摘要： Systems and methods for flow verification and validation of mass flow controllers are disclosed. A mass flow controller may be commanded to a specified flow and flow measurement commenced. During an interval, gas is accumulated in a first volume and measurements taken within this volume. The various measurements taken during the interval may then be used to calculate the flow rate. The flow rate, in turn, may be used to determine the accuracy of the mass flow controller relative to a setpoint.

摘要： Systems and methods for flow verification and validation of mass flow controllers are disclosed. A mass flow controller may be commanded to a specified flow and flow measurement commenced. Gas is accumulated in a first volume and while measurements are taken within this volume. Gas may then flow into a second volume while measurements are taken. The various measurements taken during the two intervals may then be used to calculate the flow rate. The flow rate, in turn, may be used to determine the accuracy of the mass flow controller relative to a setpoint. Additionally, these systems and methods may utilize only one volume to perform flow verification by flowing gas into this volume, taking measurements, and calculating the flow rate based only upon this set of measurements.

摘要： Methods are provided for forming loop fastener products. One method includes applying heat and pressure to a carded web in a manner which fuses fibers on a back side of the web, thereby forming a bonded web, and then embossing the bonded web to raise discrete regions of the web, each raised region containing hook-engageable fiber portions that are exposed for engagement on a front side of the web and fused on the back side of the web within the region. Another method includes placing staple fibers on a back side of a substrate; needling the staple fibers through the substrate to form a composite, thereby forming loop structures extending from a front side of the substrate; applying heat and pressure to the composite in a manner which fuses fibers on the back side of the substrate while protecting the loop structures on the front side of the substrate; and embossing the composite.

摘要： A perforating gun assembly (110) for creating communication paths for fluid between a formation (114) and a cased wellbore (116) includes a housing, a detonator and a detonating cord (136). The perforating gun assembly (110) includes one or more substantially axially oriented collections of shaped charges (122, 124, 126) each of which is operably associated with the detonating cord (136). A perforation (152, 154) is formed in the formation (114) as a result of the interaction of jets (141, 142) formed upon the detonation of at least two shaped charges (122, 126) that create a weakened region (148) in the formation (114) followed by the detonation of at least one shaped charge (124) that forms a jet (150) that penetrated through the weakened region (148).

摘要： A unique phasing pattern is provided that maximizes the effective perforation geometry of a wellbore. The improvement overcomes the problems associated with multi-phase guns of the past that failed to account for the fact that the gun rested on the low side of the casing. In one embodiment of the present invention, the phasing is arranged so that there is a zero phase tunnel formed. The zero phase tunnel is located at approximately the location where the gun rests against the low side of the well. Further, tunnels are formed by shape charges at plus and minus forty-five degrees and at plus and minus ninety degrees. This can also be referred to as a penta-phase. In another embodiment of the invention, charges can also be placed to allow for a plus and minus one hundred and thirty-five degrees pattern in addition to the penta-phase pattern described above. This expanded pattern can also be referred to as a hepta-phase pattern. By improving the phasing pattern of the perforation gun, valuable hydrocarbon fluids will encounter less resistance to flow into the well.

摘要： A detonator assembly is provided. The detonator assembly comprises a deflagration to detonation transition body, a first thermally stable secondary explosive contained by the body, and a bulkhead coupled to the deflagration to detonation transition body. The bulkhead contains pressure within the body associated with firing the detonator assembly at least until a transition from a deflagration operation mode of the detonator assembly to a detonation operation mode of the detonator assembly has occurred. A second thermally stable secondary explosive may alternatively be included in the deflagration to detonation transition body, either separated from the first thermally stable secondary explosive or mixed with the first thermally stable secondary explosive. The detonator assembly comprises effectively no primary explosive.

摘要： Methods of forming a loop product are provided. One method includes (a) needling polymeric fibers through a substrate to form hook-engageable loop structures of the fibers extending from one surface of the substrate; and then (b) using heat and pressure to locally soften and bond polymer of the fibers directly to the substrate and adjacent fibers, thereby anchoring the loop structures to resist fiber pullout under fastening loads.
