Title: Nitric acid production
Inventor: KARAU DIETER DIPL-ING
IPC: C01B21/26
Filed: 1970-01-16
Abstract: Nitric acid especially of concentration greater than 70% wt., is prepared by absorbing NO2 from nitrous gases in H2O or aq. HNO3, by compressing the gases during the absorption and by washing the residual NO2 in the gas after absorption with 60-75% HNO3, then blowing this NO2 out of the wash HNO3 at the absorption pressure by a counter-current of nitrous gases from the combustion of NH3, the HNO3 being at temperature greater than during washing; the blowing gases and the NO2 blown out are then cycled to the absorption stage.

Title: Biologically clarified waste water - applied directly to an agriculturally used surface rather than into pre-flooding tanks
Inventor: GEB BREDDIN ILSE-MARIE ARNOLD
IPC: C05F7/00

Title: Shock absorber for seat belts - spring loaded diverting roller decreases angle of contact with increasing pull
Inventor: TRAPPE RICHARD
IPC: F16F7/08
Filed: 1972-01-07
Abstract: The friction-controlled seat belt operates without any peaks during the entire operational path. The initial shock caused by inertia and other factors could cause damage to the user in case of a sudden deceleration of the vehicle. On the present arrangement the belt, before being wrapped around the actual roller - which is not rotary, but with fixed pivoting point - is wrapped around a second roller which is rotary and arranged in such a way that its pivoting point can swing around the previous roller. the swinging motion of the second roller takes place against the force of a spring. When the second roller deviates from its original position, the angle of contact on the fixed roller decreases.

Title: Automatic artillery aiming control - operational amplifiers generate flight path with range finder and aiming measurement for servo-control
Inventor: SCHOENWAELDER GERHART
IPC: G06G7/80
Filed: 1973-12-11
Abstract: An automatic range finder and aiming device for artillery uses a projectile path electronic circuit generator. Operational amplifier circuits are connected such that each generates an output voltage proportional to input voltage, with the constant of proportionality dependent upon the resistors.
