Abstract: The present invention overcomes many of the disadvantages of prior art mobile oil field heat exchange systems by providing an oil-fired heat exchange system. The present invention is a self-contained unit which is easily transported to remote locations. The present invention includes a single-pass tubular coil heat exchanger contained within a closed-bottom firebox having a forced-air combustion and cooling system. The rig also includes integral fuel tanks, hydraulic and pneumatic systems for operating the rig at remote operations in all weather environments. In a preferred embodiment, the oil-fired heat exchanger system is used to heat water on-the-fly (i.e., directly from the supply source to the well head) to complete hydraulic fracturing operations. The present invention also includes systems for regulating and adjusting the fuel/air mixture within the firebox to maximize the combustion efficiency. The system includes a novel hood opening mechanism attached to the exhaust stack of the firebox.

Abstract: The invention relates to a method of preparation and isolation of betulin diacetate from birch bark from paper mills and its optional processing to betulin, wherein the birch bark is ground, mixed with two- to twenty-fold excess volume of water and is stirred so that all birch bark is dipped, then the fraction of the birch bark which floats on the surface is collected, said collected fraction is dried at the temperature in the range of from 50 to 85 °C and the betulin contained in the dried birch bark is then subjected to an acetylation reaction, after the acetylation the birch bark is dried at the temperature of from 50 to 100 °C and the formed betulin diacetate is then isolated from the birch bark by supercritical extraction of the birch bark with carbon dioxide at the pressure of 28-35 MPa and the temperature of from 50 to 100 °C and subsequently, the supercritical extract is recrystallized for direct use or for further processing. The further processing can be basic hydrolysis of the re-crystallized betulin diacetate to betulin.

Abstract: Systems and methodologies are described that facilitate transmitting control information in wireless networks. Portions of bandwidth can be blanked for transmitting control information, and the control information transmitters can utilize beacon symbols to convey the control information. In this regard, interference is mitigated with respect to data transmissions over the control information bandwidth.  Selected frequencies of the beacon symbols in a codeword can be used to indicate the control information. The codewords can be encoded with an error control code to provide redundancy for decoding in the presence of some interference.

Abstract: In this invention, a channel estimation value of data symbols of a data channel is calculated by weighting and averaging pilot symbols in a parallel time multiplexing method. Also, a channel estimation value of data symbols during each data symbol interval is calculated by dividing data symbols in a slot into a plurality of data symbol intervals, selecting pilot symbols suitable for calculation of a channel estimation value of data symbols during each data symbol interval and weighting and averaging that pilot symbols. Also, a fading frequency is detected based on an inner product value of pilot symbols. Weighting factors are changed based on the detected fading frequency. Also, a channel estimation value is calculated by weighting and averaging pilot signals using a plurality of weighting sequences. The calculated channel estimation value is used to demodulate received data. The output data with the highest quality is selected by judging reliability of these plurality of demodulated data. It is also possible to select some weighting sequences based on the result of the reliability judgment of the demodulated data for predetermined period of time. In this case, after the selection, demodulation is performed by using these selected weighting sequences only.
