Abstract: The disclosure relates to a process for forming a deposit on the surface of a metallic or conductive surface. The process employs an electrolytic process to deposit a silicate containing coating or film upon a metallic or conductive surface.

Abstract: A multi-point communications system is set forth herein. The communications system comprises a transmitter for transmitting OFDM/DMT symbols over a predetermined number of bins across a transmission medium. The OFDM/DMT symbols are generated using at least one timing signal. At least one of the predetermined number of bins includes a pilot tone sub-symbol having a frequency corresponding to the clock signal. The communications system also includes a receiver for receiving the OFDM/DMT symbols from the transmission medium. The receiver demodulates the received symbols using at least one timing signal. The receiver has a first pilot tone search mode of operation in which the receiver adjusts its timing signal to scan the frequency range of the predetermined number of bins looking for the pilot tone sub-symbol and identifies the bin including the pilot tone sub-symbol.

Abstract: The present invention is directed to drying and heating processes and to an apparatus incorporating a pulse combustion device that can be used in a drying system or in a heating system. In general, the apparatus includes a pulse combustion device for the combustion of a fuel to produce a pulsating flow of combustion products and an acoustic pressure wave. The pulse combustion device has a combustion chamber connected to at least one resonance tube. A resonance chamber surrounds at least a portion of the pulse combustion device and includes a nozzle downstream from the resonance tube. The nozzle accelerates the combustion products flowing therethrough and creates a pulsating velocity head. In a drying system, the nozzle exits into a drying chamber where the combustion products contact a feed stream.

Abstract: An apparatus and process using a pulse combustor to atomize a liquid or slurry is provided. The apparatus includes a pulse combustor for generating a stream of atomization fluid and an oscillating flow field and introduction apparatus for introducing to the influence of the oscillating stream of atomization fluid a liquid or slurry to be atomized. Furthermore, an improved pulse combustion atomizer employing a T-shaped burner is provided.

Abstract: An improved apparatus and process for removal of particulates entrained in a gas stream are provided. The removal process employs a pulse combustor to provide an acoustic pressure wave to acoustically enhance agglomeration of particulates which may be collected and removed using a conventional separation apparatus. The apparatus may be employed as a direct fired system for improved operation of gas-operated equipment such as a gas turbine, or may, alternatively, be employed as an add-on subsystem for combustion exhaust clean-up. Additionally, added particulates may include a sorbent for effecting sorption of other contaminants such as sulfur. Various other particulates for contaminant removal may also be introduced into the system as exemplified by alkali-gettering agents.

Abstract: A method for compressing the data required to represent an image using a set of save-maps, with each save-map being identified by an index and each save-map identifying a subset of transform coefficients. The method begins by spatially partitioning the image into a plurality of blocks, includes the generation of transform coefficients representative of the data spatially located in each block; the generation of an index for each block as a function of the transform coefficients for that block; and selecting one of the save-maps as a function of the index. By employing the index and the value of the magnitude components of the subset of transform coefficients identified by the selected save-map for each block, compressed data may be obtained representative of that portion of the image spatially contained in each of the corresponding blocks.
