    Abstract: A device for monitoring the electrical conductivity of an electrically conductive fluid comprising at least two electrical coils for immersion in the fluid. One of the coils constitutes a coil to be energized with an alternating current and the other in use constitutes a detection coil. The coils are arranged relative to one another so that in use they are mutually inductively coupled and are inductively coupled by the fluid.An electronic circuit is provided which includes a power supply for supplying an alternating current to the coil or coils to be energized, and a detector for detecting the voltage induced in the detection coil or coils. The detector provides an indication of changes in the inductive coupling between the coil or coils to be energized and the detection coil or coils.

    Abstract: A method of checking and/or varying the fuel to air mixture ratio of an internal combustion engine comprises measuring the intensity of the infra-red emission from the flame during combustion in the combustion chamber by an infra-red photosensitive device and feeding the signal to an indicator, such as a meter, an audible device, or a ''''magic eye'''' device, and/or to automatic control means for effecting any adjustment that may be necessary of the fuel/air mixture ratio. Apparatus comprises a ''''Colourtune'''' spark plug provided with a tubular adaptor comprising an insulating sleeve with a longitudinal slot for the lead of the plug from one end fitting over the transparent core of the plug, and the other end of the sleeve being joined to one end of a tubular metal shield the other end of which houses a detector cell for infra-red emission mounted on an insulated plug eccentrically with respect to the insulating sleeve on the opposite side of the axis to the slot for the plug lead.

    Abstract: To maintain optimum air-fuel ratio in a cylinder of an internalcombustion engine, the operating time of a fuel injector is controlled by a logic network responding to engine speed, temperature and load as determined by respective sensors. Engine speed is measured by a pulse generator, synchronized with the engine, whose pulses are fed to a spark plug in the cylinder, to a timing circuit in the logic network and to an ionization-type flow meter in the air-intake manifold. The output of the flow meter, integrated over a number of cycles, is applied to one input of a comparator via a circuit including a thermistor which serves as a temperature sensor, the other input of the comparator receiving a progressively rising reference voltage from a timing condenser which is charged from a constant-current source. The timing circuit includes a flip-flop, periodically set by a pulse from the generator, which is reset by the comparator whenever the condenser potential reaches the output voltage of the sensing circuit and which thereupon discharges the condenser, keeping it from recharging until the arrival of the next pulse. The flipflop, when set, actuates the fuel injector by overlappingly energizing a biasing winding and a working winding thereof.

    Abstract: A liquid flow metering system comprising a flow conduit, many of such conduits having a dielectric lining supported for strength by a moisture bearing material such as concrete, the concrete itself often having still other moisture bearing material on the outside of it such as dirt, a capacitive electrode imbedded in or attached to a side wall of the conduit, a dielectric medium disposed between the capacitive electrode and the moisturebearing concrete, dirt or other material, the dielectric medium being disposed on the side of the capacitive electrode which faces away from the center of the conduit to prevent the capacitive electrode from sensing the moisture in the concrete, dirt, or other moisture-bearing material whereby the capacitive electrode senses only liquid in the conduit so as to give accurate sensing thereof.

    Abstract: A flowmeter utilizing a Beta source positioned upstream of a cylindrical capacitor formed by two spaced-apart concentric cylindrical sections. The concentric cylindrical sections form the capacitor electrodes and they are a part of two concentric, inner and outer, tubular members which are mounted in an outer housing that is adapted to be connected into a flow line so that fluid flows through both the inner and outer tubular members. The capacitor electrodes are insulated from the tubular members by means of dielectric ring members connected therebetween. Means are provided for detecting any potential difference between the two electrodes and for evacuating the space between the outer tubular member and the housing.
