Abstract: Disclosed are simplified and energy-efficient distillation processes and systems for separating a liquefied natural gas stream to obtain a natural gas stream and a national gas liquid stream. Substantial savings in construction costs and operation energy consumption can be achieved by using the processes and systems of this disclosure. Preferably the separation processes are integrated with other industrial processes such as petroleum refining, petrochemical production, chemical production, and the like.

Abstract: An H2-rich fuel gas production plant comprising a syngas production unit can be advantageously integrated with an olefins production plant comprising a steam cracker in at least one of the following: (i) fuel gas supply and consumption; (ii) feed supply and consumption; and (iii) steam supply and consumption, to achieve considerable savings in capital and operational costs, enhanced energy efficiency, and reduced CO2 emissions, compared to operating the plants separately.

Abstract: An H2-rich fuel gas stream can be advantageously produced by reforming a hydrocarbon/steam mixture in to produce a reformed stream, followed by cooling the reformed stream in a waste-heat recovery unit to produce a high-pressure steam stream, shifting the cooled reformed stream a first shifted stream, cooling the first shifted stream, shifting the cooled first shifted stream to produce a second shifted stream, cooling the second shifted stream, abating water from the cooled second shifted stream to obtain a crude gas mixture stream comprising H2 and CO2, and recovering a CO2 stream from the crude gas mixture stream. The H2-rich stream can be advantageously combusted to provide thermal energy needed for residential, office, and/or industrial applications including in the H2-rich fuel gas production process. The H2-rich fuel gas production process can be advantageously integrated with an olefins production plant comprising a steam cracker.

Abstract: An operation method for a mobile electronic device is provided. The operation method includes: transmitting a calling phone number to a wireless audio product from an operation system of the mobile electronic device via wireless communication, wherein the mobile electronic device is wirelessly connected to the wireless audio product; transmitting the calling phone number to an application software of the mobile electronic device by the wireless audio product; searching a caller name corresponding to the calling phone number by the application software of the mobile electronic device; transmitting the caller name to the wireless audio product by the application software of the mobile electronic device via wireless communication; and playing the caller name by the wireless audio product.

Abstract: A method for activating mammalian SIRT1 in a cell comprising: providing a compound of formula (1): and incubating the cell with the compound. Also provided is a method for extending life span of a subject comprising: providing the same compound; and administering the compound to the subject. Yet also provided is a method for treating a mammalian SIRT1 inactivation-related disease in a subject comprising: providing the same compound; and administering the compound to the subject.

Abstract: A transmission device for an exit device for a door includes a base (10) to which a transmission member (4) and a driving member (6) are pivotably mounted. A pushed section (611) of the driving member (6) abuts a push portion (421) of the transmission member (4). A link (7) is movably mounted to the base (10) and is connected to a latch of the exit device. When the transmission member (4) pivots from a first angular position to a second angular position, the push portion (421) of the transmission member (4) pushes the pushed section (611) of the driving member (6) to pivot the driving member (6) from a third angular position to a fourth angular position, and a push section (621) of the driving member (6) pushes a pushed portion (712) of the link (7) to move the link (7) for retracting the latch.

Abstract: A latch device for an exit device (1) includes a base (20) mounted to a side of a door. A first sliding member (30) is mounted to the base (20) and is movable relative to the base (20) between a first position and a second position. A stop (72) is mounted in a receiving portion (322) of the first sliding member (30) and is pivotable relative to the first sliding member (30) between first and second angular positions. A latch head (60) is mounted to the base (20) and is pivotable relative to the base (20) between a retracted position and in extended position. An abutment portion (725) of the stop (72) in the second angular position is located in a pivotal path of the latch head (60).
