Patent GB-2296365-A (GB)
Title: Sounder
Inventor: HUGHES STEPHEN TIMOTHY
IPC: B06B1/02
Filed: 1994-08-16
Abstract: A sounder has a drive coil (40) which receives a varying signal from a drive circuit. The magnetic field resulting therefrom drives an armature (12) which is mounted on a diaphragm (10) which produces sound due to the vibration thereof. A second coil (42) is magnetically and electrically connected to the drive coil (40). A diode (D1) is connected in series with the second coil and is arranged such that no current flows in the second coil (42) when the drive signal (which is unipolar) generates a current in the drive coil (40). When the drive signal is cut off, a current flows in the second coil (42) and charge is stored in a capacitor C1. The energy thus stored may be used to power the drive circuit. In this way, the power used by the sounder corresponds to the losses in the circuit and due to the acoustic power radiated by the sounder. Since this is only a small proportion of the power needed to drive the drive coil (40), the sounder is efficient. <IMAGE>

Title: Channel equalisation in telecomms system
Inventor: BOOTH ANDREW JOHN
IPC: H04B3/04
Filed: 1996-04-20
Abstract: In a distribution telecommunications system, channel data for performing equalisation on a channel between a central station and an outstation is determined from measurements on pairs of pulses transmitted from the outstation. Each pulse pair comprises a first in-phase pulse and a second quadrature pulse having a predetermined time/phase separation. Coefficients for an active filter provided at the outstation are calculated from the multipath transmissions of the pulses and from the received time/phase separation of those pulses. This can be for cable TV using ATM.

Patent GB-2310572-A (GB)
Title: Control System for a Telecommunication System
Inventor: COOPER GUY ALEXANDER
IPC: H04B1/707
Filed: 1996-09-13
Abstract: The present invention provides a client station and method for controlling a telecommunications system, the telecommunications system including a central station and a server station. The server station is arranged to maintain an object model thereon representing the central station, and is connectable to the central station to send control signals to the central station in accordance with the object model. The client station comprises a communications manager for establishing a connection with the server station to enable communication between the client station and the server station, thereby to manage the object model maintained on the server. The client station has a memory for storing a portion of the object model, and a processor for processing commands received by the client station to determine whether status information associated with each object in the portion of the object model should be altered, and for altering the status information based on said commands. By this approach, the time taken to load object model information on the client station is decreased, since only a portion of the object model is loaded when the client station initially connects to the server station. Further, by retaining only a portion of the object model on the client station, there is no longer the memory requirements that keeping a complete copy would entail. Preferably the telecommunications system being managed is a wireless system in which the central station communicates with subscribers via wireless connections, but the invention is not limited to wireless systems.

Title: Quantitative detection of chemical species
Inventor: JOHNSON MARK
IPC: G01N21/17
Filed: 1995-12-08
Abstract: A method and apparatus for determining the concentration of a target chemical species in a sample. A first spectrum is generated representing the absorbance of the sample across a range of wavelengths. The sample is then exposed to conditions which modify the concentration of the target chemical species in the sample, for example by irradiating the sample with UV or visible light which degrades the target chemical species, or generating an active species flux through the sample by exposing the sample to a corona discharge. The absorbance of the sample is then remeasured across the same range of wavelengths and differences between the two spectra are analysed to quantify the concentration of the target chemical species in the unmodified sample

The communication device may be a two-way radio (10), and some of the components are a radio transmitter (12), a radio receiver (14), an antenna (16), an amplifier (18), a battery (20) and a housing (22).
Patent GB-2330687-A (GB)
Title: Field emission devices
Inventor: TUCK RICHARD ALLAN
IPC: H01J9/02
Filed: 1997-10-22
Abstract: A field electron emission cathode is manufactured by depositing on an insulating substrate 300, by low resolution means, a sequence of a first conducting layer 301, a field emitting layer 302 and a second conducting layer 303 to form at least one cathode electrode. There is then deposited on the cathode electrode by low resolution means, a sequence of an insulating layer 304 and a third conducting layer 305, to form at least one gate electrode. The structure thus formed is then coated with a photoresist layer 306. The photoresist layer 306 is then exposed by high resolution means to form at least one group of emitting cells, the or each such group being located in an area of overlap between a cathode electrode and gate electrode. To complete the cells, the conducting and insulating layers 305, 304, 303 are etched sequentially to expose the field emitting layer 302 in the cells, and remaining areas of the photoresist layer 306 are removed. Thus, field emitting materials and devices can be manufactured using relatively low cost techniques. The cathode is particularly useful for matrix addressed flat panel displays.

Title: Apparatus and method for friction welding an impeller of a pump
Inventor: MOON SEONG-DAE
IPC: F04D29/62
Filed: 1997-11-07
Abstract: Apparatus and method for manufacturing an impeller consisting of a body (11) with vanes and a shroud (13) to be welded to the body (11). The apparatus comprises a die (30) for chucking the body, a horn (40) for supporting the shroud to be in contact with the vanes while the body is chucked by the die, a torque motor (20) for applying vibration to the horn, and a pneumatic cylinder (50) for giving pressure to the torque motor so that the shroud and the body are pushed in a contacting direction with each other. The torque motor (20) may be driven by half-wave rectified alternating current, and generates twisting vibration of the frequency between 10 Hz and 1 kHz. By the half-wave rectified current, rotational shaft (23) is rotated at a fine angle when the half-wave rectified current is ON, and torsion bar (25) is twisted. During the period the current is OFF the torsion bar (25) which has been twisted is returned to its original state, therefore as the current is repeatedly turned ON/OFF, the rotational shaft (23) vibrates with the same frequency as the applied alternating current.
