Title: Feed water control system for steam generator - has temp. sensor and takes account of water level change time lag
Inventor: HOCEPIED RENE G
IPC: F22D5/30
Filed: 1975-07-01
Abstract: The system regulates the water supply to the base of a steam generator in a nuclear power station. Feed water and steam flow are measured, also water level in the generator, the respective signals being fed to a unit emitting a control signal to the valve opening mechanism. the feed water temperature is also measured and a corresponding signal fed to the unit to effect a change in its behaviour. The change takes account of a time lag or delay in the level alteration as the water feed rate is varied. There can be a small capacity valve parallel to a large one, only the small one being adjusted for small variations, while the large one is adjusted after the small one is fully open.

Title: Power regulation for discharge lamps - for two level lamps has triacs in parallel with series inductances
Inventor: TCHANG LIANG ING
IPC: H05B41/42
Filed: 1975-12-08
Abstract: The circuit regulates gas discharge lamps which are required to work at two power levels. The change in power is achieved by shorting out an inductance in series with each lamp (1). The switching circuit is independent of the supply to the lamps. Each extra inductance (6) is in parallel with a triac switch (7) The gate of each triac is controlled by a full wave bridge rectifier (10) itself fed from a step-down transformer (8). Power for the transformer is derived from the same line phase as the lamp (4a). A switch (12) in the neutral line (3) to the bridges changes the power level.

Title: Gas turbine exhaust directive system - uses jets destroying recirculation bubbles for gas diversion
Inventor: MARIAME PHILIPPE
IPC: F01D25/30
Filed: 1975-12-30
Abstract: The system deflects the exhaust of the gas turbine to one of two outlets, e.g. to a waste heat boiler and to atmosphere, operating on the principle of a bistable amplifier. A rectangular power jet delivers the gas, and two gas passages with flat walls discharge to one or the other of the outlets. A divider parallel to thejet lengthwise axis is mounted at the rear end in the direction of gas flow, deflecting it to one of the outlets. Two control jets discharge behind the power jet, and one or the other is pressurised so as to destroy the recirculation bubble, due to Coanda effect, along the flat wall adjacent to this jet, thus deflecting the gases towards the flat wall adjacent to the other jet.

Title: Controlling ventilation of tunnels and galleries - using anemometer for automatic sampling of natural air currents to drive fans in direction requiring least power
IPC: E21F1/00
Filed: 1976-07-16
Abstract: The ventilation system of tunnels and galleries is automatically sampled to establish the most favourable direction of varying natural air currents.
