Title: Magnesium recovery from the bisulphite black liquor - magnesium oxide containing gases from the burning of neutralised liquor is scrubbed with black liquor
Inventor: HORNKE RUEDIGER DR
IPC: D21C11/06
Filed: 1974-01-23
Abstract: The magnesium oxide serves to neutralise the black liquor and keep in soln. the otherwise volatile org. acids which would be lost from the evaporators and which have a heat potential. The resulting slurry is settled out and the magnesium hydroxide fed to the SO2 absorbers to make digester liquor. The decanted neutralised black liquor is evaporated and incinerated to form the magnesium oxide which is then scrubbed out as above.

Title: Socketed pipe coupling axial locking device - has flat washer distorted into cone on screwing thrust ring home
Inventor: SEILER GEORG
IPC: F16L21/04
Filed: 1974-04-01
Abstract: The device is particularly for use with ductile cast-iron pipes, where the smooth cylindrical end of one pipe fits, leaving an appreciable clearance, in the socket of another one. The socket is internally screwed, and then tapers inwards to accommodate a distorting sealing ring compressed by a thrust ring screwing into the socket. An annular clamping portion is situated between the thrust ring conical end face and the sealing ring and grips the smooth pipe end. A closed washer fits between the conical face of the thrust ring and the clamping portion, and on screwing the thrust ring home in the socket thread this is distorted from the flat condition perpendicular to the socket axis into a conical form.

Title: Black-and-white and PAL colour television signals - with additional digital signals transmitted during horizontal blanking periods
Inventor: RAPPOLD ARMIN DIPL ING
IPC: H04N11/16
Filed: 1974-04-22
Abstract: The additional digital signals are transmitted during the back porch, and their frequency corresponds to that of the auxiliary colour carrier.
