Title: reducing radionucleide contamination of a metallic component
Inventor: SOLLY ALFRED RICHARD
IPC: C25F7/00
Filed: 1996-11-15
Abstract: Apparatus for reducing radionuclide contamination of a metallic component includes a concentrated spray nozzle 16 mounted on an articulated positioning arm 26 arranged to traverse completely a surface 28 of a component of a nuclear plant upon de-commissioning and subject to radio-active contamination. The nozzle 16 is connected, as a cathode, to an electrical power source 32 to give an electrical current density of approximately 50 amps per tenth square metre with the component connected as an anode. An electrolytic treatment liquid 20, such as 5% nitric acid solution, is discharged through the nozzle 16 to react with at least any metallic oxide surface layer to dislodge or detach any radionuclide particles, such as particles of cobalt 60, attached to the surface 28. The electrolytic treatment liquid 20 drains to a shallow reservoir formed by the component or to a separate reservoir 18 and is then passed to a settling tank 10 and fine filter 20 where the radionuclides settle out or are filtered out and the liquid re-cycled.

Title: Adaptive controller for actuator, eg loudspeaker, systems
Inventor: KLIPPEL WOLFGANG J DR ING
IPC: G05B13/04
Filed: 1998-03-20
Abstract: An arrangement for converting an electric input signal into an acoustic or a mechanical output signal comprises a transducer 19 such as a loudspeaker, a controller 15 and a parameter detector 17. The output 23 of the controller is connected via the parameter detector to the terminals of the transducer. The controller has a parameter vector input 24 to change the linear or nonlinear transfer characteristic of the controller. The parameter detector comprises an error circuit 31 and update circuit 33. The error circuit 31 measures an electric signal at the terminals of the transducer and generates an error signal e(t) which describes the difference between the measured electric signal and an estimated electric signal derived from the output signal or other state signals of the controller. The update circuit 33 estimates transducer parameters by minimizing the amplitude of the error signal. The estimated parameters are supplied both to the error circuit 31 and to the controller 15 to adjust the controller to the particular transducer and to compensate for distortion in the mechanical or acoustic output signal.

Title: Concurrent recording and playback of broadcast material
Inventor: MILLER ALEX JOHN JAMES
IPC: H04N5/44
Filed: 1998-10-23
Abstract: An apparatus and method for recording broadcast material wherein a buffer signal store is used to concurrently store received broadcast material and display the stored material after a user defined time delay. A user-operable control allows adjustment of the time delay imposed by the buffer signal store. As described, a set-top box 100 receives broadcast material from sources such as satellite, terrestrial or cable or material broadcast via the Internet. This material is recorded using a recording/replay device such as video storage device 70, or a random access memory device, at the request of the user e.g. via remote control 110 (also see fig.14) or automatically in response to a viewing interruption such as an incoming telephone call at telephone 50 or the doorbell monitor 95 indicating the doorbell ringing and the door being answered. Replay is then re-initiated manually by the user when the interruption has ended. The buffer continues to store received broadcast material in concurrence with the user viewing its contents.

Title: Electronic throttle control system
Inventor: TANG LIANG
IPC: F02D11/10
Filed: 1999-11-22
Abstract: An electronic throttle control system for smoothing a throttle plate position command, prior to it being used by a closed loop throttle control unit 10, has a smoothing module 12. The system determines the difference between a current throttle plate command and a received throttle plate command in order to generate a difference value. The system then sequentially indexes through a lookup table which stores a series of values of a smoothing function at predetermined time intervals. The series of values are then multiplied, one at a time, with the difference value in order to generate a series of smoothing values, and these smoothing values are added, one at a time, to the current throttle plate position command, to generate a series of smoothed throttle plate position commands which are applied to the throttle control unit.
