Abstract: A thermally driven gas resonance device comprises a resonance tube (3) which expands in cross-section along its length from one end to the other, a heat source (2) located at the one end of the resonance tube, and means (2, 4) to trigger oscillations in a gas in the resonance tube. The heat source (2) is preferably a pulsed heat source having a pulse repetition frequency corresponding to a resonant frequency of the gas resonance tube (3). The mechanical energy produced in the oscillating gas in the gas resonance device may be used to operate a pressure swing gas separator by including a bed (16) of molecular sieve material in the other end of the resonance tube (3). Alternatively, the mechanical energy may be used to drive a heat pump (19). In this case a heat sink (21) is located at the other end of the resonance tube (3), a regenerator (20) is also located adjacent the other end, and means (8) on the side of the regenerator (20) towards the heat source (2) effect heat exchange between the gas in the resonance tube (3) and a source of low grade heat.

Abstract: The present invention relates to the thermal decomposition of explosive nitrate esters in process waters of the explosives industry. The dissolved esters are subjected to a temperature between 150 and 300 DEG C at a pressure above the vapour pressure of the waste water. In the course of this the nitrate esters are completely decomposed, and the waste water treated in this manner can then be fed to further processing and purification. In a preferred embodiment, the hot waste water leaving the decomposer is utilised for preheating the process water prior to its entrance into the decomposer.

Abstract: An improved circuit and a method of making precise time of arrival measurements on optical pulse data of relatively varying widths are disclosed. The invention provides an analog input signal (B) representing received optical pulse data, along with a delayed version (A) of the analog input signal (B). The time of delay is set such that the original analog signal (B) and the delayed analog signal (A) cross each other at a predetermined point. This cross-over consistently occurs at the same point on the signal independent of the size or shape of the analog pulse. Preferably, the cross-over occurs at approximately 70 % of the maximum analog signal amplitude. The cross-over point between the original signal (B) and the delayed signal (A) triggers the generation of the leading edge of a time of arrival pulse (E). <IMAGE>

Abstract: A method of estimating the channel impulse response (CIR) of a communication system is disclosed. The method comprises providing a first estimation of the CIR by an impulse response calculation, using correlation of signals to determine tap weights for the calculation, thereby providing a set of amplitude values within equally time spaced bins. The true path delay of a radio channel represented by the significant peaks in the first estimation is determined, by reference to amplitude values of those of the bins which surround the bin having the greatest amplitude. A refined estimation of the CIR is calculated using the significant peaks, such that these peaks represent substantially all the energy represented by the first estimation of CIR.

Patent GB-8925892-D0 (GB)
Title: Signal processing method and sound source data forming apparatus
IPC: G10H7/00
Filed: 1989-11-16
Abstract: A method for processing a digital signal produced by digitizing an analog signal such as a musical instrument sound signal, and an apparatus for producing sound source data. When the input signal contains a periodically repetitive wave form portion, the fundamental frequency and its high harmonic components of the input signal is extracted by a comb filter prior to signal processing which takes advantage of the periodicity of the input signal. The fundamental frequency or pitch is detected by performing Fourier transform to produce frequency components, phase matching these frequency components and performing inverse Fourier transform. When extracting a repetitive waveform portion or so-called looping domain, such looping domain having the highest similarity in waveform in the vicinity of both ends of the domain is selected. When the bit compression of digital signal data is performed by selecting a filter with blocks each consisting of plural samples as units, a pseudo signal is affixed to the input signal, before the start point of the input signal, which pseudo signal will cause a filter of the lowest order to be selected. The looping domain is set so as to be a whole number multiple of the block which serves as the unit for bit compression, and the parameters of the looping start block are formed on the basis of data of the start and the end blocks. By applying a part or the whole of the signal processing method to a sound source data forming apparatus, sound source data may be formed which is reduced in the looping noise and error caused by data compression and which is of superior sound quality.
