Title: Gas humidifier particularly for medical oxygen - ensures adequate wetting without entrainment of water droplets
IPC: A61M16/16
Filed: 1972-12-01
Abstract: To ensure efficient humidification, a gas stream is split into multiple threads, e.g. via a sintered metal porous element, before passing through water, usually distilled for medical use.

Title: Support for movable vertical air filter washing tube - has suspension head with 3 point contact on horizontal angle rail
IPC: B01D46/42
Filed: 1975-01-08
Abstract: The suspension head of a vertical washing tube moves on a horizontal rail by means of 3 sliding contact points that combined exert a press. more than the total wt. of the movable assembly.

Title: Optical modulator for communication systems - utilises light beam delay time to effect the necessary modulation
IPC: G02F1/03
Filed: 1975-02-18
