Title: Improved power meter
Inventor: PAYNE KENNETH
IPC: G01R35/04
Filed: 1993-03-13
Abstract: An apparatus for measuring electrical power is described wherein the apparatus is adapted to produce an output signal proportional to the product of a supply voltage and current flowing through a connected load. A first signal proportional to the supply voltage and a second signal proportional to the load current are used to inverse modulate (at 5 and 4 respectively Fig 1 not shown) the period of two constant frequency carrier signals to provide third and fourth signals. Intervals between successive pulses in the third signals input at 10 fig 2 are digitised by subtracting at 20 counts of a cycling counter 40 at successive pulses. The average interval corresponding to zero voltage is subtracted at 22 to give an instantaneous voltage value 38 which is multiplied at 26 with a similarly derived current value 39 to give instantaneous power consumption. <IMAGE>

Title: Display system facilitating computer assisted audio editing
Inventor: NORTON MARK J
IPC: G11B27/34
Filed: 1993-12-30
Abstract: A display system represents an audio track as a discrete waveform, wherein each sample in the waveform may take on one of a discrete range of possible values. The discrete waveform indicates the presence of sound energy above user-set thresholds. Audio data samples are smoothed and applied to one or more thresholding functions. The resulting discrete output is displayed by using graphics of either different size or different color. An editor using display system in conjunction with a computerized editing system receives an indication of where sufficient sound levels occur on the audio track. This information may be used to locate breaks in sound, dialog and other sound effects, which simplifies audio editing and synchronization of audio with other media in a multimedia presentation. Similar thresholds may be applied to the results of frequency analysis to provide an indication of which frequencies are present in the audio's signal.

Patent GB-2304021-A (GB)
Title: Regeneration of tidal mud flats
Inventor: KIRBY ROBERT
IPC: E02B3/04
Filed: 1995-05-12
Abstract: A method of regenerating tidal mud flats which have a degraded or eroding profile includes the steps of ascertaining the ambient tidal range and wave climate of a mud flat to be regenerated and deriving from these data a new, regenerated profile for the mud flat, and depositing densified or dewatered mud or clay on the mud flat to build the new profile. The wave climate, and hence the sedimentary regime, of the mud flat is modified by breakwater or barrier means to render the mud flat receptive to deposition and retentive of the deposited mud or clay to preserve the regenerated profile. The breakwater or barrier means may be an offshore, floating breakwater adapted to suppress high and short-period waves but to permit the passage of low and long-period waves.
Patent GB-2319409-A (GB)
Title: Transceivers
Inventor: SHERLOCK MARK
IPC: H03L7/107
Filed: 1996-11-15
Abstract: Traditional radio transceivers, such as those used in the base stations of cellular mobile systems require delicate manual tuning. Regardless of the accuracy of the initial tuning, an uncompensated oscillator provides little compensation for temperature drift and component ageing. The invention provides a method of stabilising the frequency of a phase locked loop provided that a stable reference voltage (VREF) is available. During recalibraton, control unit (7) applies, via switch (SW1), reference voltage (VREF) to the input of a voltage controlled oscillator (6). An adjustable control element (5) of the oscillator is adjusted until the frequency of the oscillator (6) is within a predetermined deviation from its nominal value. Detecting either a period without any up or down pulses originating from phase detector (2), or that the output voltage of integrator (4) equals the reference voltage (VREF) indicates correct tuning. The control unit (7) is enabled by a signal EN from a radio station and controls the switch SW1 and the gain of element (5) in dependence of a signal indicative of frequency difference between oscillator (6) and a reference signal frequencies.

Title: A low noise single ended input/differential output rf amplifier
Inventor: SOUETINOV VIATCHESLAV IGOR
IPC: H03F3/343
Filed: 1997-01-11
Abstract: An amplifier, suitable for RF applications, has good noise properties because of a special configuration of transistors 201 - 203. Transistors 201 and 202 are connected in a cascode configuration, to overcome the Miller effect. Transistors 202 and 203 have their bases driven by a common current source. The main current paths from ground to each of output terminals 221, 222 are essentially noise free. Transistor 201, acting as a transconductance amplifier, does introduce some noise though this is minimised by the use of an inductor 210. Transistor 304 forms a current source for the current path to output terminal 222. A differential output is achieved at terminals 221, 222 by way of transistors 202, 203 having complementary outputs. In another embodiment (Figure 4, not shown), a capacitor is connected across the collector and base electrodes of transistor 202 to introduce a further stage of gain.

Title: Cleaning limiting current type solid electrolyte sensor
Inventor: YAGI HIDEAKI
IPC: G01N27/417
Filed: 1997-03-21
Abstract: To remove the effects of deterioration of the characteristics of a limiting current solid electrolyte sensor 1, the sensor is cleaned by applying a voltage opposite to that used during measurement. The amount of diffusion of the gas is preferably limited by porous electrodes which provide gas diffusion limiting holes. A DC measuring voltage V a or V b is normally applied across the electrodes of the sensor 1 and the resulting limiting current measured. The sensor is cleaned by applying a reverse voltage V c of absolute value less than the measuring voltage(s) for a time set by the timer circuit. The measured value of the limiting current immediately before the cleaning is commenced is held in the holding circuit. The sensor described may be used to measure oxygen or water vapour.

Title: Actuator for a valve
Inventor: RAWSON MICHAEL S
IPC: F16K31/04
Filed: 1997-10-15
Abstract: A valve actuator preferably driven by a electric motor is disclosed. The valve actuator is useful with surface safety valves and uses power input from an electric motor to position the valve in its normal position. A mechanism is provided to allow the valve to shift position to a failsafe position upon failure of electrical power to the motor connected to the actuator. A screw drive is provided with the motor, with a latch mechanism (figure 2, not shown) holding a nut 50 against rotation. The nut can advance longitudinally upon rotation of the drive to move a valve stem 18. Upon failure of electrical power, the latch mechanism releases the nut from a coupling 16 in the actuator which is connected to the valve stem, and the main return springs in the actuator allow the nut to rotate with respect to the screw drive so that the valve can assume its failed position. Normal applications allow the valve to fail closed; however, the valve can be configured so that failure results in opening of the valve if the application requires it.

Title: Switch mode power supply; arc welding
Inventor: GEISSLER STEVEN
IPC: G05F1/08
Filed: 1997-01-07
Abstract: A switch mode power supply has a controller with a voltage feedback circuit and a constant current circuit which causes the output current to be substantially constant over an output voltage range 903. An arc welding power supply includes a switch mode inverter or converter with an adaptive hot start circuit enabling additional current to be supplied at start up, the amount of additional current being dependent on the output voltage. The supply may have a V-A characteristic, Fig.9, with a constant voltage portion 901 leading via a droop portion 902 to a constant current portion which is operative at output voltages found under typical welding conditions. A dig portion 904 provides increasing current with decreasing voltage below a dig voltage threshold, the maximum dig current being user adjustable. At start up, the welding current is increased to twice the user set value for a predetermined period, plus additional current spikes as the output voltage crosses above and below the dig threshold, Fig.10. In a series resonant converter (Figs.1-6) which controls converter switching to give a desired constant current output, the voltage on a resonant tank capacitor and the current through the converter switches are sensed to determine if a dangerously high voltage would be generated on the capacitor during the next cycle of converter operation. The converter switches are not enabled for the next cycle until the capacitor voltage has bled down to a safe level. The converter may be used for induction heating, or may be combined with additional circuitry (Fig.8) to provide a welding supply having the aforementioned V-A characteristic and start up operation.
