Title: Leak detector and indicator for fluid conveying pipes etc. - has pressurised monitoring chamber and pressure switches to control optical and-or acoustic alarm
Inventor: BERG JOST
IPC: B65D90/503
Filed: 1991-10-25
Abstract: The leak indicating device (10) for double-walled containers, tubes (1), etc. for storing and transporting flammable and non-flammable fluids, has a pressurised monitoring chamber (2).

Title: Controlling of gray scale in gas discharge panels - subjecting anode of panel to pulses with variable amplitude to control luminance differential
Inventor: KIM SANG-CHEOL
IPC: G09G3/28
Filed: 1993-03-26
Abstract: The method for controlling the gray scale of gas discharge display screens involves using the anode (AN) of a display (10) selectively coupled to voltages derived from a 150V and 70V supply (VC,VB) . The switches (51,52) are switched at rates related to the horizontal synchronising signal period. The voltage (VA) applied to the anode varies linearly between 70V and 120V within the synchronising period. This allows the gray scale level to vary dependent upon the luminance difference to maintain an accurate level. ADVANTAGE - Precise luminance differential for fine gray scale. Improves reproduction quality by modulating both pulse width and pulse amplitude.

Title: Method for evaluating recorded image signals (picture signals, video signals) for an image sharpness display
Inventor: SEEGERT BERNHARD DIPL ING
IPC: H04N5/232
Filed: 1993-08-11
Abstract: In the case of LCD viewfinders having a low resolving power (resolution capability), there is the disadvantage that the image-recording element (CCD) has a higher resolution, and so optimum image-recording monitoring is not possible.
