摘要： An apparatus and process for separating a feed liquefied natural gas containing at least methane and a hydrocarbon less volatile the methane, into a product natural gas enriched with methane and lean in hydrocarbon less volatile than methane and a heavier fraction lean in methane and enriched with hydrocarbon less volatile than methane. The process includes heating the feed liquefied natural gas in a heat exchanger, passing the heated fluid into a distillation column, withdrawing the heavier fraction from a bottom of the column, and withdrawing a residue gas from a top of the column. The process also includes liquefying at least part of the residue gas in the heat exchanger, refluxing a part of the liquid portion of the fluid obtained in the liquefying step into the column, and withdrawing, as the product natural gas, the remainder of the liquid portion.

摘要： A supervisory and control system for a time division switching system supervising and controlling signals transferring to and from all or some of line interface equipment such as a digital trunk, analog trunk equipment, the intra-office line concentrators or remote line concentrator through a signal path. In the signal control, the signal is classified into two kinds of signals: one for cyclically controlling a state and the other for randomly controlling the same. Those signals are multiplexed in a single time slot to control the various line interfaces. Signal time slots having different multiframes and signal time slots with a plurality of periods are supervised depending on a signal path class thereby to reduce the number of laying cables among interframes.

摘要： A line concentrator for a time division data switching exchange. Asynchronous and synchronous data signals generated at asynchronous and synchronous data terminals are subjected to known multi-point and synchronous sampling to become a train of bit-multiplexed first asynchronous and synchronous data channel signals. Responsive to a train of bit-interleaved read-in pulse groups timed relative to the respective synchronous data signals, an arithmetic unit stores the data channel signals in an octet memory according to the asynchronous and synchronous data terminals. Responsive to a train of read-out pulses appearing for the respective data terminals, the arithmetic unit reproduces groups of uninterleaved data channel signals for each data terminal and composes the reproduced data channel signals into a train of second asynchronous and synchronous data channel signals given by a common and uninterleaved bit format. The line concentrator is readily modified for decomposition of a train of asynchronous and synchronous data channel signal groups of the bit format into replicas of the original data signals.
