Abstract: A permanent magnet generator having the unique feature of a speed proportionally adjusted air gap for self-regulation of coil output voltage over a wide range of operating rotational speed of a steam turbine to which the invention is coupled. The Permanent Magnet Generator rotor is supported by the turbine end shaft and the stator is supported by a bracket bolted to the turbine pedestal base or other rigid structure. The speed proportional air gap is accomplished through the use of a plurality of centrifugal flyweights in mechanical coupling to a spool piece under spring load and to corresponding rare earth magnets via linkage such that increasing rotor speed extends the flyweights outward from the rotor center of rotation and draws the rare earth magnets closer to the rotor center of rotation and thus increases the air gap.

Abstract: A flowmeter is based on the principle of injecting a pulse of microwave radiation into a flowing stream of material containing a substance having an absorption band for the radiation so as to heat a small quantity of the substance and continue its flow in a conduit to a downstream temperature sensor where the temperature of the quantity is sensed for enabling determination of the time elapsed for the quantity to travel from the point at which the microwave energy is injected to the sensor. A microcontroller receiving signals from the sensor determines when the peak temperature of the quantity is sensed and uses the peak to terminate measurement of a time interval. The time interval starts when the microcontroller senses that the ac sinusoidal power has passed through zero at which time the microwave generator, such as a magnetron, emits a pulse of microwave radiation for heating the quantity of the substance of the material flowing in the conduit.
