Granted: 1982-12-15
Abstract: A device for determining the average period of a low-frequency periodic signal comprises a counter receiving stepping pulses from a high-frequency pulse generator and resetting pulses from a phase-angle detector monitoring the periodic signal. A shift register is loaded with the count of the counter in response to each pulse generated by the detector, an adder at an output of the shift register emitting a signal coding the sum of the contents of this register. Another shift register is loaded under the control of the detector with the output sums of the adder and has a first and a last storage cell connected to a substractor which emits a signal indicating changes in average period. Further registers and summing circuitry may be inserted between the adder and the additional shift register for increasing the number of periods taken to form each average-period estimate.

Abstract: A device for converting a stream of a slurry or liquid flowing down a tube into a flat stream having a uniform flow across its width and, if a slurry, a uniform particle size distribution across that width. The device comprises a vertical tube (11) from which the slurry or liquid may flow onto a horizontal first plate (12) in an even laminar flow and a second plate (20) adapted to receive medium flowing over the edge of the first plate (12) disposed below the first plate (12) and inclined relative thereto. Means are provided to meter the amount of medium flowing onto any one increment of the width of the second plate (20) so that it will be substantially equal to the amount of medium flowing down any other increment of equal width. The metering is achieved by the use of first plate (12) having a closely defined peripheral shape or by the use of vertical dividing members (13) spaced around the periphery at unitform angular spacings which direct the medium onto equal width increments of the second plate (20).
