Title: Removing contaminants from a clarified liquid stream outlet in a settling tank
Inventor: BEAUMONT MICHAEL JOHN
IPC: B01D21/24
Filed: 2003-05-08
Abstract: A process for retaining solids in a treatment vessel while discharging a clarified liquor comprises a treatment vessel with an internal discharge pipe (1, Fig 1). In use, contaminated liquor enters the treatment vessel wherein a reaction takes place and suspended solids are allowed to settle at the bottom of the vessel. During the reaction and settling period some suspended solids collect in the discharge pipe and are periodically removed by a reverse flow of the clarified liquor. Preferably a pump 6 supplies a motive force to the clarified liquor which is either contained in a flushing tank 7 for removing suspended solids from the discharge pipe or held in main storage tanks. The contaminated liquor may comprise a leachate of rain water contaminated with chemicals and organic material mixed with bacteria and air. Advantageously suspended solids in the treated leachate are reduced and can therefore be discharged to a sewer or water course.

Title: RDS decoder
Inventor: TAURA KENICHI
IPC: H04L27/00
Filed: 2002-12-10
Abstract: An RDS decoder includes a synchronous demodulator 1 and a data decoder 2. The synchronous demodulator 1 receives a multiplex signal in which an RDS signal based on digital data is superimposed on an FM audio signal and generates a baseband RDS signal from the RDS signal. The data decoder 2 decodes the baseband RDS signal generated by the synchronous demodulator 1 into the digital data. The synchronous demodulator 1 includes a quadrature demodulator 3 which converts the multiplex signal into two baseband signals which differ in phase by 90 degrees, a filter 4 which removes unwanted components having frequencies higher than a predetermined frequency level from the two baseband signals to reduce sample data, and a phase-locked loop 5 which receives the two baseband signals output from the filter and generates the baseband RDS signal to be input to the data decoder from the two baseband signals. The phase-locked loop detects and corrects phase error remaining in the baseband RDS signal.

Title: Dimming control of lamps and electrical lighting systems
Inventor: HUI RON SHU-YUEN
IPC: H05B41/392
Filed: 2003-08-27
Abstract: There is disclosed an energy-saving dimming method and apparatus that can be used to convert a wide range of existing "non-dimmable" electric lighting products and systems into "dimmable" ones. Examples of non-dimmable electric lighting systems are (i) high-pressure and low-pressure discharge lamps powered either by magnetic ballasts or by some electronic ballasts, (ii) incandescent lamps and (iii) a group of electric lighting systems. Based on a new integrated approach of a voltage-vector control and reactive-power control concept, the voltage applied to the lighting systems can be varied smoothly without handling the real-power of the lighting system. Consequently, the proposed dimming device and method can be used as a general-purpose, energy-saving dimming approach to the dimming of a wide range of "non-dimmable" electric lighting systems. By inserting a voltage vector through an energy-efficient switched-mode reactive-power-control circuit, the resultant voltage can be controlled and varied as a variable and controllable voltage source for dimming many electric lighting systems such as existing magnetic ballast driven gaseous discharge lamps systems and incandescent lamps.

Title: Apparatus and method for generating a complementary cumulative distribution function (CCDF) curve
Inventor: JOHNSTONE COLIN
IPC: G01R19/17
Filed: 2005-05-13
Abstract: In apparatus for generating a Complementary Cumulative Distribution Function (CCDF) curve for an input signal 1, an analog to digital converter (ADC) 3 samples the input signal at sampling points 2 to provide a parameter value corresponding to a desired parameter of the input signal at each sampled point. A memory element 4 provides a frequency count of occurrence of each received parameter value from an address in the memory corresponding to the received parameter value. An adder 5 receives the frequency count, increments the count and provides the incremented count to an input of the memory element 9 for writing back into the address corresponding to the received parameter value. A CCDF curve generating module 6 reads the frequency count stored in the memory element corresponding to each parameter value and generates a CCDF curve therefrom. The memory can be a dual port memory and can have two banks of data A and B.

Title: Apparatus and methods for deploying logging tools and signalling in boreholes
Inventor: EASTER CHARLES RICHARD
IPC: E21B47/18
Filed: 2002-08-13
Abstract: Apparatus 10 for signalling between a downhole location in a wellbore and a further location remote from the downhole location comprises a conduit extending into the wellbore 12, a pump 11 connected to the conduit to supply fluid under pressure, a modulating valve 26 at a downhole location to modulate the fluid pressure, a programmable processor 23 for controlling operation of the modulating valve and a remote transducer 27 for detecting fluid pressure at said further location. In operation the control device sends control signals via the fluid that are detected by the downhole transducer wherein the processor causes actuation of one or more tools. Following actuation of the tools the modulating valve generates signals in the form of pressure changes in the fluid. The remote transducer detects and displays the signals to indicate at the surface whether deployment of the tool has occurred successfully. A later embodiment relates to a method of using said apparatus.

Title: Receiver for a quantum cryptograhpy communication system
Inventor: YUAN ZHILIANG
IPC: H04B10/70
Filed: 2003-08-18
Abstract: A receiver 401 for a quantum communication system includes polarising filters 451, 453 positioned before photon detectors 408, 410 to remove any erroneous orthogonal components of photon polarisation. Each filter is configured to pass only photons of a predetermined polarisation to a corresponding detector and is preferably placed between a decoder and the detector. The filters may be integrated with optical fibres within the receiver and may be polarising sheets or polarising beam splitters. In another embodiment (fig. 4) a bright clock signal is transmitted to the receiver (303) in order to assist with the detection of encoded photons carrying bit values. It is believed that the intense clock pulses interact with the fibre (305) along which they pass generating unwanted photons at other wavelengths. To address this problem a band pass filter (325) is placed before the photon detector (329) of the receiver to block all photons except for the encoded photons. Application is to Quantum Key Distribution (QKD).
