| INFORMATION/ ADVERTISEMENT SCREEN BASED ON GAS-DISCHARGE DISPLAYS |
| The batch production has been launched of a.c. and d.c. gas-discharge displays for typesetting community screens. The devices have no analogs, are protected by patents, and are produced in batches.
The gas-discharge-display (GDD) screens fully meet the most exacting present-day requirements to television display screens.
Several color display screens have already been developed, which function in accordance with EGA and VGA standards.

| NON-CONTACT MEASURING GAUGE |
| Russian scientists have designed a new non-contact measuring gauge protected by a Russian patent and based on the same principle of level registration as gamma relays. This measuring gauge, however, is free from the principal shortcoming of gamma relays: it lacks any artificial radio nuclide sources. The natural background gamma radiation always present in the environment is used instead. |
