The present invention is a field-deployable system for separating methane and natural gas liquids (NGLs) from a raw gas stream comprising a compressor; a dehydrator; a refrigerator having one or more stages; and a separation subsystem adapted to separate the raw gas stream into three product streams including a methane stream that is at least 80% methane, an ethane-rich stream, and a NGLs stream having a vapor pressure of no more than 250 psia at 38° C. The methane stream is sufficiently lean to be useable in existing natural gas engines without modification. The NGLs stream has a sufficiently low vapor pressure to be transportable in standard propane containers. The ethane-rich stream may be utilized within the system itself to power its own operations. The system can be utilized to reduce flaring from liquids-rich gas production sites to an absolute minimum, produce natural gas liquids for transport, and provide dry methane gas suitable for use in portable field generators.

Steel frames formed of rolled steel I-beams are connected by steel framed wall panels spanned by steel studs, and covered by steel framed roof panels spanned by steel purlins, making a structural frame completely formed of steel components bolted together. All components are precut and predrilled before transport to a construction site.

The invention relates to ammonia synthesis loops containing gasses, which do not react and would accumulate if they were not purged out. By the present invention ammonia in a purge gas is recovered by an adsorption agent operating at the full synthesis loop pressure. The adsorption agent is chosen in such a way that the ammonia can be removed again by passing a gas comprising hydrogen and nitrogen through it at the same elevated pressure as the loop pressure. This enables the adsorption agent to be regenerated by fresh synthesis gas coming from the synthesis gas compressor just before this gas enters the synthesis loop. Thereby, the regeneration requires an absolute minimum of energy consumption and equipment.

In a wireless communications system operating according to CDMA or the like, when one terminal simultaneously performs communication using multiple wireless resources (e.g., multiple carriers), there was a problem that when it was attempted to guarantee network mobility by the same soft handoff system as in the case where communication was performed using only one wireless resource, efficiency suffered from the viewpoint of network forwarding load, processing load and wireless resource occupancy time. Soft handoff termination is judged and soft handoff is forcibly terminated according to whether or not the data rate obtained for all resources on the network side satisfies a requested rate, based on a reception state notification from a terminal concerning wireless resources. By performing this processing, the soft handoff period is shortened, sufficient received strength in the terminal is maintained and terminal mobility is guaranteed, while at the same time network forwarding load, terminal processing load and wireless resource occupancy time are suppressed to the absolute minimum.

A method includes determining a pressure difference across a scroll compressor of a cooling system. The pressure difference is compared to a minimum differential pressure value. Pressure differences across the scroll compressor that are less than the minimum differential pressure value are associated with unloading the scroll compressor. Parameters including a pressure set point value and an absolute minimum pressure value are increased when the pressure difference is less than the minimum differential pressure value. Subsequent to the increasing of the parameters, the parameters are decreased when the pressure difference is greater than a sum of the minimum differential pressure value and a hysteresis value.

In a heddle (6), the slender heddle shank (21) has been lengthened, at the cost of the end eyelets (7, 8) and the yarn eyelet region (29). This is accomplished on the one hand by shortening the end eyelet regions (7, 8) to their absolute minimum length and on the other by placing the auxiliary openings (38), which serve to transport the heddles, closer to the end eyelets (7, 8). The radii R in the region of the end eyelets (7, 8) are reduced. Instead of the usual 2 mm width, the heddle shank (21) still has a maximum width of 1.6 mm. The regions (14, 13) of the heddle (6) that protrude past the end openings still have, instead of the usual length of 4 mm, a length of 2.5 mm to 3 mm. Directly around the yarn eyelet (33), the heddle has a width which, as before, is equivalent to twice the width of the yarn eyelet (33). However, the length of this region is shortened to a maximum of twice to three times the yarn eyelet width. The transition from the narrowest zone (27, 28) of the heddle shank (21) to the comparatively wide zone (29) around the yarn eyelet (33) is characterized by an elongated transition region (34), which has a maximum width of 1.8 mm and serves to reinforce this region against mechanical stresses.

Minimum-memory-implementation is available with any depth and period in DSL interleaving / deinterleaving, always allowing the minimum amount of memory to be used in both transmitter and receiver without loss of performance or of basic triangular structure, even if the interleaver / deinterleaver parameters change dynamically. A novel cell-scheduling process ensures availability of the minimum amount of memory (or any other desired memory usage) to implement an image of the perfect triangle and works for any co-prime depth and interleaver period. Minimal memory use may be further characterized by a simple off-line method that determines an addressing order for each of the memory cells in a minimum-memory (or other) implementation of an interleaver / deinterleaver according to the invention. Time variation of interleaver depth in operation can be accommodated easily with absolute minimum memory requirement at all time instants.

A method, computer program product, and data processing system for managing a input / output buffer cache for prevention of deadlocks are disclosed. In a preferred embodiment, automatic buffer cache resizing is performed whenever the number of free buffers in the buffer cache diminishes to below a pre-defined threshold. This resizing adds a pre-defined number of additional buffers to the buffer cache, up to a pre-defined absolute maximum buffer cache size. To prevent deadlocks, an absolute minimum number of free buffers are reserved to ensure that sufficient free buffers for performing a buffer cache resize are always available. In the event that the buffer cache becomes congested and cannot be resized further, threads whose buffer demands cannot be immediately satisfied are blocked until sufficient free buffers become available.

Also, an absolute minimum operating frequency is provided that results in the control algorithm shutting down the chiller system and the compressor.

A motion vector estimation apparatus that can produce motion vectors accurately with an adequately expanded search domain, without increasing computational load too much. A reference macroblock mover moves a reference macroblock in a given reference frame according to a current search pattern, starting from a point identified as a minimum point in a preceding evaluation step. An evaluation processor calculates evaluation values corresponding to specified search movements, thus extracting a minimum evaluation value among as many evaluation values as the number of search movements performed. The evaluation processor finally finds an absolute minimum point from the extracted minimum evaluation values. A search pattern generator provides search patterns specifying extended search movements in a vertical direction so as to move a reference macroblock across different field lines. A motion vector estimator calculates a motion vector representing a distance and direction of the original macroblock relative to the reference macroblock at the absolute minimum point.
