According to some embodiments, a cryogenic storage tank includes a manway formed in a body of the cryogenic storage tank. An inner manway lid is coupled to an inner wall of the cryogenic storage tank and disposed over at least a portion of the manway. An outer manway lid is coupled to an outer wall of the cryogenic storage tank and disposed over at least a portion of the manway. The inner and outer manway lids are configured to retain pressure within the cryogenic storage tank.

According to some embodiments, a system for a submerged pump includes a cryogenic storage tank and a pump chamber. The pump chamber is suspended from a top of the cryogenic storage tank in a vertical orientation. The pump chamber includes a liquid pump operable to pump cryogenic liquid from the cryogenic storage tank.

A plurality of highest intrinsically-ranked parser outputs are scored using an extrinsic metric that is relevant to one or more downstream applications. The parser can be trained by using an extrinsically highly-ranked parse selected from among the intrinsically highly-ranked parses. The selected parse need not be the highest intrinsically-ranked parse. In this way, a parser can be trained to produce better results for downstream applications.
摘要:
New ligands, compositions, metal-ligand complexes and arrays with pyridyl-amine ligands are disclosed that catalyze the polymerization of monomers into polymers. Certain of these catalysts with hafnium metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, isobutylene or styrene. Certain of the catalysts are particularly effective at polymerizing propylene to high molecular weight isotactic polypropylene in a solution process at a variety of polymerization conditions.

A liquid natural gas filling system structured to store a cryogenic fluid at a low pressure and fill a use vessel at a high pressure. The filling system includes a first, low pressure vessel, at least one second, high pressure vessel, a plurality of conduits, each conduit in the plurality having a valve, extending between, and in fluid communication within the first, low pressure vessel and the at least one second, high pressure vessel, a pressure building means coupled to the at least one second, high pressure vessel and structured to raise the pressure of a cryogenic liquid within the at least one second, high pressure vessel, and an outlet nozzle structured to be coupled to a use vessel, the outlet nozzle coupled via the plurality of conduits to, and in fluid communication with, the first, low pressure vessel and the second, high pressure vessel. The filling system is structured so that a cryogenic liquid may be stored in the first, low pressure vessel at a low pressure. The cryogenic liquid at a low pressure may further be transferred to the at least one second, high pressure vessel via the plurality of conduits. The pressure of the cryogenic liquid at a low pressure in the at least one second, high pressure vessel may be increased to a high pressure by actuating the pressure building means. Thus, the cryogenic liquid at a high pressure in the at least one second, high pressure vessel may be transferred from the at least one second, high pressure vessel to a use vessel via the plurality of conduits and the nozzle.
摘要:
Multiple verification cases consisting of code sequence and initial context, and suitable for electrical verification testing of a device, are generated from a single verification case by permuting, or changing, the code sequence, by either permuting the initial context of the code sequence or permuting the code sequence itself. The code sequence is an array of computer instructions to be executed by a computer and the initial context of the code sequence refers to the environment in which the code sequence is to be run.
摘要:
The operating-point differentiated test results are obtained by running a code sequence on the device at a first operating point to generate predicted results and then running the same code sequence on the device at a second operating point defined by changing an electrical parameter of the first operating point to generate actual results. Any differences that might exist between the predicted and actual results are due to the changed operating point of the device.
摘要:
A metrological instrument for measuring surface characteristics such as surface form of a component (300). The instrument includes a slideway (32) to cause relative movement between a surface sensing probe (84) and the component which allows the probe to traverse a surface of the component. A probe carriage (80) supports the probe to allow the probe to move as a body in a measurement direction relative to the carriage so as to follow a surface being sensed. An optical sensor (82) provides a signal indicative of the displacement of the probe relative to the probe carriage. A controller (83) acts in response to a signal from the optical sensor, to move the probe carriage so as to maintain the probe in an operational range. A further sensor (11) measures measurement of displacement of the probe in the measurement direction as it follows a surface during use of the instrument.
