Title: Redn. of emission of oxides of nitrogen in exhaust gases - from diesel engines by addn. of inert gases to air supply
Inventor: TESHIROGI NAOHISA
IPC: F02B47/08
Filed: 1974-09-13
Abstract: Control of the emission of oxides of nitrogen in the exhaust gases of a diesel engine by the addn of inert gases to the air supplied to the diesel, the novel feature being that the exhaust gases from a petrol engine are used as the inert gases. The known effectiveness of partly recirculating exhaust gases in reducing the amt of NOx, in the exhaust gases discharged to atmosphere, which is unsatisfactory in the case of the diesel due to the presence of particulate material and SO2, can be secured by the use of an auxiliary petrol engine. The quantity of inert gas required is about 20% of the air intake, NOx emission is reduced to one third.

Title: Viscosity change determn. eg. in polystyrene polymn. - by strain gauges on stationary paddle in reactor with stirring arms
Inventor: BRUN LIONEL
IPC: B01J19/00
Filed: 1975-01-24
Abstract: The sudden change in the viscosity of a mass in motion, i.e. of the phase reversal during the manufacture of polymers (polystyrene) is determined by dipping a stationary paddle into the vessel in which the mass is agitated by a stirring arm. Strain gauges are attached to a metal rod on which the stationary paddle is fixed and the bending stress indicated by them indicates sudden viscosity changes. This is a simple method which can be readily applied to large-scale process engineering. It requires no calibration whatsoever and is based solely on the changing amplitude of the strain and not on its absolute value.
