Title: Indirect measurement of line of vision direction - uses mark placed in line of observer's vision and aligned with target by observer's head movement
Inventor: KORN AXEL DR RER NAT
IPC: G01S5/16
Filed: 1976-06-29
Abstract: The mark placed in the field of vision in a fixed manner relative to the observers head, aligned with the target point by head movement.

Title: Desulphurised flue gases neutralisation - by adding ammonia before feeding to water cooling tower
Inventor: HOELTER HEINZ
IPC: B01D53/50
Filed: 1977-10-01
Abstract: When flue gases from the desulphurisation plant of fossil fuel fired power stations are introduced for dilution into cooling towers of the wet type, the residual SO2 forms sulphuric acid and has destructive effects. This can be overcome by injecting ammonia into the tubular feed sections of the flue gases to neutralise them. The SO2 is oxidised to ammonium sulphite or ammonium sulphate and the cooling water is neutralised. Any pollution to the environment by the residual 10-20% SO2 is thus obviated.
