Title: Indicator for measuring thickness
Inventor: HENNESSY JOHN BRIAN
IPC: G01B11/00
Filed: 1980-10-30
Granted: 1984-08-02
Abstract: A distance indicating device comprises a probe having therein a light source and light sensitive element to receive light reflected from the surroundings of the probe. A reference point is movable relative to the probe. The light sensitive element gives rise to an electric signal. A first storage means stores a signal representing the maximum reflected light returned to the light sensitive element. A second storage means stores a signal representing the light returned to the light sensitive element representing the minimum reflected light. A selection means selects a signal level between the maximum and minimum stored signals' and a measuring element measures the distance between the reference point and a further reference point, associated with the probe, when the signal level reaches the selected signal level.

Title: Method and device for the automatic oversuction on electrolysis containers for the production of aluminum
Inventor: DUPRAT GEORGES
IPC: C25C3/06
Filed: 1985-05-02
Granted: 1988-04-07
Abstract: A process for automatically going into the mode for increased suction extraction of the gases emitted by the tanks of series for the production of aluminium by igneous electrolysis using the Hall-Heroult process, each tank being closed around its periphery by a plurality of removable covers which are disposed in substantially sealed relationship with each other and between each thereof and their support means on the periphery of the tank, the gases being collected over each tank by at least one duct connected to a centralized suction extraction system. The temperature of the gases in the duct is continuously measured. Opening of at least one cover gives rise to an abrupt drop in temperature, which makes it possible to put the system into the increased suction extraction mode, which will be automatically stopped when, all the covers being closed again, the temperature of the gases will substantially resume its initial value. The power required for the suction system is thus substantially reduced.
