Title: Surface aeration of waste water basing
Inventor: JOSEF MUSKAT DR RER NAT
IPC: B01F7/02
Filed: 1969-04-03
Abstract: An aeration rotor is movable on a given path above the surface of the water.

Title: Fixing of the 'no-cut' state for gas welding - /cutting
Inventor: SUZUKI ROKU
IPC: B23K5/22
Filed: 1969-04-12
Abstract: Determination of the 'no-cut' condition during gas welding/cutting where a pressure medium emerges close to an orifice belonging to a welding or cutting device and its exit pressure is used as counter presser while the different counter-pressures which act on the pressure medium serve to note these 'no-cut' conditions. The pressure of the emerging pressure medium is previously set to such a balance condition, that in normal operation, there are no variations in the atmospheric pressure about the exit point. Compressed air can be used as the pressure medium.

Title: Adjustable seat hinge for car - with simple axial drive to operate geared lock for collision support
Inventor: RUEHMANN BERNHARD
IPC: B60N2/22
Filed: 1973-09-26
Abstract: The seat back is attached to a hinge part whose end is stamped to form a gearing with inwards directed teeth and a depression to locate the outer gearing of a locking ring.
