Title: Cartridge-type water treatment appts - for prodn of potable water
IPC: B01J47/02
Filed: 1971-12-22
Abstract: Device comprises means for softening, filtering, mineralising and gasifying water and for applying other treatments if necessary. In order to simplify the regeneration of the resins used in the softening process and to exchange the prodts. of the other treatments, cartridges, for throwing away after use, are employed. An optical control indicates when the cartridges are exhausted and should be replaced. While previous devices merely supplied a softened water, the new device yields a water which has been gasified and mineralised to ones personal taste. The water reaches the appts. through a multi-way valve which has been calibrated to suit the capacity of the cartridge for the partic. treatment; the water flows through thr cartridge into a reservoir compartment and a pipe brings the treated water back to the next, identical treatment chamber. The appts. comprises as many treatment units as necessary and the contents of the cartridges vary according to their posn. in the appts. They are changed when needed by removing the plug which holds them in posn. A stopper at the bottom closes the unit and allows access to the inside; this stopper can include the withdrawal system for the treated water.

Title: Detection of obstacles in railway tunnels - surface wave line and wave generator connected to end of line
IPC: B61L1/20
Filed: 1973-05-11
Abstract: A surface wave line is fixed in the space,a wave generator is coupled to one end of the line i.e. 'line input', and the signal received at the other end of the line i.e. 'line output' is detected, also reflected signals at the 'line input'.
