Title: Smoke prevention on incinerator exhausts - using final water cooling to drop water content of gas stream
IPC: F23J15/00
Filed: 1974-09-04
Abstract: Exhaust gases from a waste incinerator are treated as follows to prevent the emission of white smoke (a) the gas is cooled, (b) wet scrubbed, (c) cooled with water to a low temp. to dehumidify it and reduce the saturation of the gas (d) released to atmosphere.

Title: Auto-control of drinking water treatment with oxidising agent - uses electrolysis to monitor residual agent in treated water
Inventor: VIGOURET JEAN
IPC: G01N33/18
Filed: 1975-08-06
Abstract: The oxidising agent to be measured is changed by chemical action into a second oxidising agent which is more reducible. The second oxidising agent is electrolysed between two electrodes held at a low difference of potential, e.g., 0.5-0.7 volts. During periodic reversals of electrode polarity, the measured intensity of elctrolysis current is proportional to the amt. of first oxidising agent to be measured. The first oxidising agent is pref. chlorine which is changed into residual iodine by reaction with an excess of potassium iodide, the liberated iodine being electrolysed. Pref. both electrodes are made of the same metal and have equal surface areas; in partic. the electrodes are both tubular helices, one inside the other, with electrolyte flowing between them. Pref. the amt. of residual oxidising agent in the treated water is monitored continuously, results are compared with a standard value and the treatment adjusted accordingly. The installation can be calibrated after chemical titration of standard samples. The proportion of oxidising agent is continuously and automatically regulated to precisely that required for optimum treatment; a slight but not significant excess of oxidising agent can opt. be assured.

Patent FR-2323877-A1 (FR)
Title: Combined silencer and antipollution device - has cylindrical swirl chamber with central pickup pipe leading to slotted rectangular mixing box
IPC: F01N1/14
Filed: 1975-09-10
Abstract: The exhaust gases from an internal combustion engine flow through the pipe (A) into the cylindrical chamber (B) with a swirling motion. This swirling motion reduces the pressure of the gases and assists the flow from the engine. The gases flow through holes in the tube (C) and flow out in an axial direction into a rectangular box (E) with a large number of rectangular slots. Atmospheric air flows through these slots cooling and mixing with, the exhaust gases. This causes the exhaust gases to contact and reduces the noise of impact with the atmosphere. Pollution is reduced by admitting air through the pipe (F) to ensure complete combustion of any unburnt gas in the chamber (B).

Title: AC measurement in HV line - employs fibre optic conductors transmitting electroluminescent diode output to receiver
Inventor: BOIRAT ROBERT
IPC: G01R15/22
Filed: 1976-01-14
Abstract: Alternating current flowing in a high voltage line such as at 250 RV is measured using a Faraday cell close to the line. Electroluminescent diodes transmit the cell output via fibre optic conductors to a receiving unit remote from the high voltage lines. The alternating current in a line (2) is coupled (4) to a diode bridge (D1-4) close to the line. Two diodes (D1-2) are electroluminescent diodes producing light for transmission by fibre optic conductors (F1, F2) to a receiver (R1, R2). A differential circuit (14) produces an output in a sense corresponding to current flow and an indicator (16) measures the output. A balance control (10) compensates for mismatched diode (D1, D2) characteristics.

Title: Counter current washing of gravity filter - with automatic periodic operation using simple and economical plant
IPC: B01D/
Filed: 1976-08-20
Abstract: An appts. for the countercurrent washing of a granular filter bed consists of a pipe at the end of which is a ball valve, in the space above the bed, within the filter chamber. Above the filter chamber is a chamber where filtrate accumulates, open at the top and operating at a constant level during normal filtration by gravity. This filtrate chamber is fed by a pipe connected to the space below the filter bed. Water to be filtered enters froma fed tank through a pipe entering the copper part of the filter chamber. Filtrate leaves through a rising pipe connecting the space below the filter bed to the discharge. As the bed becomes choked with sediment, the static pressure in the filter chamber increases. The ball valve is forced away from its seating and the pressure in the filter chamber falls, allowing water to flow from the filtrate chamber to the space below the filter bed and into the upper part of the filter chamber, passing upwards through the bed and cleaning it. the pressure redn. may be brought about by a float valve. The apps. is simpler and costs less than existing appts. The ball can be replaced by another one with different lifting force from different granular filter beds.

Title: Vortex fluid flow meter - has conduit restrictor inducing vortex and frequency monitor to measure frequency of vortex produced
IPC: G01F1/32
Filed: 1976-09-07
Abstract: A fluid flow metering device includes a restriction (21A) in the cross sectional area of that region of conduit in which measurement of the flow takes place. Within this restriction is mounted an impeller device (16) and (17) which generates a vortex in the flowing fluid. The generated vortex has a varying frequency which is directly correlatable to the fluid flow rate. A signal processing unit (15) is employed to monitor the fluid vortex frequency and convert this into an indication of flow rate.
