Title: Particle segregation in pulverised fuel burner
Inventor: GODOY SANDRA MARIA ANGELICA
IPC: F23D1/00
Filed: 1995-05-12
Abstract: A flow divider 7 located in the primary stream of a pulverised fuel burner leads to particle segregation by size. The different streams 4 and 5 carrying the segregated fuel are directed into the optimum zones of the near burner region, for reduction of NOx and fine particles emissions depending on the burner application. This is achieved, in the case of pulverised fuel burners used in the power industry, by tapering the flow divider so that the smaller particles are fed at a greater velocity and into the centre of the recirculation zone.

Title: CPSK spread spectrum communication
Inventor: MORI MASAHARU
IPC: H04B1/707
Filed: 1992-03-20
Abstract: In a transmitter, CPSK modulation is effected by selecting either a first PN code train or a second PN code train depending on the data bit value, the first train consisting of a repetition of first PN codes having a predetermined period, and the second train being formed by delaying the first train (fig. 3). In a receiver the input is correlation-demodulated with a PN code train inverted in time with respect to the first train, and is then CPSK-demodulated in a demodulator in which a data bit is determined to be 1 or 0 depending on whether the output of an up/down counter 2950 is positive or negative. The correlator output is compared with a threshold in a comparator 2940, the output of which passes via AND gates 2942, 2944 to the up and down inputs respectively of counter 2950. The second inputs of gates 2942, 2944 respectively receive a first time window pulse train GP and a second time window pulse train SGP, formed by delaying the first pulse train. The period of each of pulse trains GP, SGP is a half of the PN code period (T1, Fig. 4). The outputs of gates 2942, 2944 are also summed in a counter 2954 connected to an ND converter 2956, whereby the reference threshold input to comparator 2940 rises stepwise over the duration of a bit period. <IMAGE>

Title: Production wells having permanent downhole formation evaluation sensors
Inventor: TUBEL PAULO
IPC: E21B47/01
Filed: 1996-02-09
Abstract: A downhole control system for a production well is associated with permanent downhole formation evaluation sensors which remain downhole throughout production operations. These formation evaluation sensors may include, for example, neutron generator, gamma ray detector and resistivity sensors which can, in real time, sense and evaluate formation parameters including important information regarding formation invading water entering the producing zone. Significantly, this information can be obtained prior to the water actually entering the producing geological formation and therefore corrective action (i.e., closing of a valve or sliding sleeve) can be taken prior to water being produced. This real time acquisition of formation data in the production well constitutes an important advance over current wireline techniques in that the present invention is far less costly and can anticipate and react to potential problems before they occur. In addition, the formation evaluation sensors themselves can be placed much closer to the actual formation (i.e., adjacent the casing or downhole completion tool) than wireline devices which are restricted to the interior of the production tubing.

Patent GB-971247-A (GB)
IPC: G06F5/08
Abstract: 971, 247. Electric digital data storage. BECKMAN INSTRUMENTS Inc. April 18,1963 [April 19, 1962], No. 15224/63. Heading G4C. A data storage unit acting as a buffer between input-data line 10 and output line 25 comprises a relatively small capacity magnetic core memory 11 and a delay line store 17 employing interlacing of data characters. As described each character is received in a seven-bit code and transmitted in parallel to be stored in seven delay lines, each storing 6, 013 bits, the spacing between successive ly entered bits in the lines being 32 bit positions (16 per sec.). In order to enable the storage of characters, which may be received in random manner, in the order in which they are received, two special characters S1, S2 are entered into the delay lines to mark the beginning and end of the sequence, their entry being controlled by unit 30. Initially the delay lines are cleared by a signal on line 33 (normally recirculation is by line 20) and then control unit enters character S1 followed by S2 after a 32-bit delay. Data characters can now be transferred from core memory 11 and this is done by sensing the arrival of character S2 at read circuit 19 by means of unit 47 and over lines 49 and 59 passing a signal to read out a data character and pass it to the gates 15 for writing, provided the memory 11 is not empty. A signal is also passed over line 51 to enable the counter 32 to start counting clock pulses, and it then continues to unload characters from 11 into the delay lines every 32 bit times until 11 becomes empty, when a signal on line 38 causes 30 to enter S2 into the lines at the next output from 32, and then disable 32. When more data characters are received, these are entered in similar manner by inserting the first in place of S2 and adding S2 after the last. When data is to be read out a signal on line 35 causes at the next reading of S1 the closure of gates 13 to cancel this character, and the opening of the output gates for each subsequent character by the 32-bit counter 31. When unloading is stopped the output gates are closed and the 31 character inserted in place of the last character read-out. Figs. 3-8 (not shown) illustrate the logical circuitry in more detail.

Title: Sound insulating structure
Inventor: WATANABE KYOICHI
IPC: B32B7/022
Filed: 1997-09-24
Abstract: The invention relates to a sound insulating structure 20 including low-density 24 and high-density layers 26. The low-density layer has first and second fibrous layers 28, 30 and ranges from 0.5 to 1.5 kg/m 2 in surface density. The first and second fibrous layers are respectively made of first and second thermoplastic synthetic fibers. The first and second fibers respectively have first and second single fiber diameters, each of which diameters is in a range of from 3 to 40 ~ m, and first and second fiber lengths, each of which lengths is in a range of from 10 to 100 mm. The high-density layer is formed on the low-density layer and is made of an air-impermeable polymer material and has a surface density that is higher than that of the low-density layer and ranges from 1 to 10 kg/m 2 . The low-density layer is high in sound-absorption coefficient and at the same time low in spring constant. Therefore, the sound insulating structure becomes substantially improved in sound insulating capability. The structure may be used in motor vehicles.

Title: Broadband sonar method and apparatus for use with conventional sonar sensor arrays
Inventor: MIKLOVIC DONALD L
IPC: G01S3/808
Filed: 1996-07-25
Abstract: A broadband sonar system in which a broadband output from a conventional narrowband sonar sensor array is used to capture broadband acoustical input signals. A single broadband beamformer receives the input from each of the sensors (such as hydrophones) of the array. The broadband output signal from each sensor of a particular subarray is coupled to a corresponding one of a plurality of first filters. Each first filter emphasizes those frequencies of each subarray which have the least noise. In addition, the output is attenuated for frequencies below the design frequency, with lower frequencies being attenuated to a greater degree than higher frequencies. A plurality of second and third filters, each corresponding to a subarray, are provided to compensate for the effects of the frequency and sensor spacing on the signal as the beam rotates. In the preferred embodiment of the present invention, the second filters attenuate certain channels as the beam approaches broadside in a manner that provides near optimum performance. The transfer function of each of the second filters remains constant over a range of beam angles computed by a sector allocation processor. When the beam angle being computed is outside the range, a new transfer function is presented to each second filter by the sector allocation processor. The output of all of the channels are presented to a single broadband focused sector beamformer which sums the outputs from each channel in accordance with a beamforming algorithm.

Title: Range determination using pseudonoise
Inventor: HONDA SHOICHIRO
IPC: H04B1/3822
Filed: 1998-02-16
Abstract: In order to determine the distance between two stations, the first station transmits a RF signal modulated with a pseudonoise signal. This is received by the second station which converts the received signal to baseband, correlates it as it comes in with a stored copy of the pseudonoise signal and determines the instant at which the correlation peak. This may be done by differentiating the correlation and detecting changes in sign of the differential. In a second embodiment, the first station transmits RF modulated by pseudonoise. This is received, delayed and retransmitted by the second station along with a signal indicating the delay. The first station correlates the signal that it receives with a stored copy of the transmitted signal to determine the maximum correlation in the same way as the first embodiment; this is used with the transmission time and the delay information to give the distance between the stations. The second station may also correlate the signal that it receives with a copy of the pseudonoise signal, and transmit a stored copy of the pseudonoise signal.

Title: Adaptively-coded digital video signal recording arrangement
Inventor: SOTODA SHUJI
IPC: H04N7/52
Filed: 1995-09-25
Abstract: A video signal recording device for recording a digital video signal coded by using motion compensation prediction and orthogonal tranformation (eg according to MPEG), includes means for judging the degree of deterioration of a picture when the video data is coded and decoded on the basis of said motion compensation prediction and orthogonal transformation, and means for adaptively changing the data rate of the coding in response to the output of said judging means. The coding data rate information is multiplexed with other additional information (eg audio data and error correction code data) which is added to the coded video data to be recorded, or is written in a predetermined region of the recording medium. The data coding may be effected in a first means which codes a video signal (including at least an intra-frame encoded frame) with quantisation at a rough quantisation level, or codes a thinned said video signal, or codes a low frequency region of said video signal subjected to orthogonal conversion, and in a second means which codes a residual difference component derived from the output of the first means, the data rate in the first or second means being adaptively changed.

Title: Laser sound detection
Inventor: LANGDON ROGER MARTIN
IPC: G01H9/00
Filed: 1999-01-15
Abstract: Detection of remote acoustic signals is achieved using a pulse to pulse coherent laser beam 20 which is projected from a telescope 19 to a remote region 21 that contains acoustic signals from a nearby source, not illustrated. Light from the beam 20 is scattered in the region 21 and a resultant signal 23 collected by a telescope 24. The signal 23 and a reference 27 are applied to an interferometer 26 and the resultant interference pattern 28 applied to a photoreceiver 29. An alternating current 30 is produced across the photoreceiver 29 which corresponds to the scattered light from the beam caused by the periodic movement of acoustic signals through region 21. The detector 10 can be used to determine the curvature of an acoustic signal wavefront and to detect the location of a source producing the acoustic signals.

Title: Phase change analysis
Inventor: KLEINBERG ROBERT L
IPC: E21B49/08
Filed: 1999-06-04
Abstract: A fluid sampling tool is fitted with a pumpout module 12 that can be used to draw fluids from the formation, circulate them through the instrument, and then expel this fluid to the borehole. It has been determined that certain measurements would be most valuable to implement down hole, such as the formation fluid bubble point and dew point. Accurate bubble point and dew point measurements are made by forming bubbles or a liquid drop in a measured sample, and detecting same. For the bubble point measurement, cavitation may be formed by modest localised pressure reductions, such as are found in acoustic waves. An ultrasonic transducer (103, fig.6) may be used, and the bubbles are sensed at the location of the ultrasonic transducer. The dew point is measured in accordance with figures 8 and 9, wherein a coder and heater (60, 62) constitute predetermined sites for detecting a liquid drop.

Title: Status bits for cache memory
Inventor: WATT SIMON CHARLES
IPC: G06F12/08
Filed: 1999-06-08
Abstract: Data processing apparatus comprises a memory 14 (e.g. cache) operable to store a plurality of data words, each data word being associated with at least one status bit (e.g. valid bit) giving information regarding a status of said data word; a status bit store operable to store said status bits within a hierarchical relationship such that a combined status relating to a plurality of first level status bits 18 at a first level within said hierarchical relationship is indicated by a second level status bit 22 at a second level within said hierarchical relationship, said second level being higher in said hierarchical relationship than said first level; and status querying logic operative to determine a status of a data word within said memory by examining status bits within said status bit store starting at a top level within said hierarchical relationship and working down through said hierarchical relationship until a status bit is reached that indicates said status of said data word independently of any status bits lower in said hierarchical relationship. In this way a global or large-scale change to status bits may be made by modifying relatively few higher level status bits within the hierarchical relationship thereby achieving a high speed change with reduced levels of special purpose hardware being required.
