Patent GB-989738-A (GB)
Title: A method of controlling the generator frequency used for the recording of a clock-pulse sequence
IPC: G04D7/12
Filed: 1961-09-27
Abstract: 989, 738. Magnetic drum stores. OLYMPIA WERKE A.G. Sept. 27, 1961 [Sept. 27, 1960], No. 34679/61. Addition to 981,382. Heading G4C. [Also in Division H3] The method and device of the parent Specification for recording a clock pulse train on a magnetic drum is modified in that a frequency deviation of the pulse generator from that required to record the number of clock pulses desired, is corrected by means of a control voltage dependent on the difference between the number of pulses generated and the number required, said control voltage being effective to adjust the pulse generator frequency towards the correct value. The arrangement of the parent Specification is modified in that the counter Z which counts the generator pulses α to be recorded provides in addition to an output i 4 , after 100 pulses, further outputs i 14 , i 24  after 80 and 120 pulses respectively. Further circuits I, II are provided which are effective when the auxiliary pulse W 0  on the drum is lagging or leading respectively with respect to the pulse i 4 , the outputs of these circuits being connected to a frequency determining control member for the pulse generator G. In operation, assume that the pulse W 0  leads on the output pulse i 4  by 13 generator pulses. The counter output pulse i 14  having changed over a flip-flop F5 after 80 generator pulses, W 0  opens a gate U 6  thereby changing over a flip-flop F 7  to enable a gate U 8  to pass generator pulses to a rectifier Gl2 whose output, as a positive control voltage, is applied to a control circuit S s  for the generator G as an adjustment for the frequency of the generator. The counter output i 4 , after 100 pulses is effective to reset the flip-flop F 7  thereby shutting the gate U 8 . The number of α pulses passed to the rectifier Gl2 determines the magnitude of the adjustment to the generator G. When W 0  lags on the pulse i 14 , the circuit I is effective to adjust the generator frequency in the opposite sense. In the event that the auxiliary pulse W 0  is substantially correctly timed, the situation is that of the parent Specification.

Abstract: <PICT:1082143/C1/1> <PICT:1082143/C1/2> Apparatus for the mechanical production of acoustic vibrations for use in dispersion comprises a plurality of liquid whistles arranged in parallel in a pipe system carrying the fibre-bearing liquid, means for closing each whistle to the passage of said liquid and for passing a flushing liquid in the reverse direction through the jet structure of said whistle to clear its jet outlet, and means for keeping at least one whistle always in operation to maintain the flow of fibre-bearing liquid.  Fig. 1 illustrates in cross-section part of an apparatus showing a liquid whistle with a rotatable jet structure in its operating position. The jet structure 6 is mounted on shaft 7 in a housing 8 in which it can be rotated through 90 degrees to bring it in line either with the axis of the jet outlet or with an inlet port 9 and outlet port 10 for the flow of the flushing fluid, for example, high-pressure water. The vibratory blade 11 is supported externally of the bell 4.  This method of mounting permits the blade to be adjusted axially relative to the jet structure for varying the action of the whistle.  In Fig. 3, the jet structures are mounted on shafts 7A and 7B which are linked by arms 15A and 15B to a rod 16 actuated by the ram of a pneumatic cylinder 17 to which air is supplied through a solenoid-operated valve 18.  The solenoid is energized through an electrical connection 19 by a pressure-actuated switch 20 which may be of the diaphragm type and which communicates with the inlet pipe 3.  The fibre-bearing liquid flows through the jet structures on 7A and when there is a blockage of these jets, the pressure of the liquid rises in 3, the pressure switch 20 operates to cause shafts 7A and 7B to rotate through 90 degrees, bringing the jet structures in 7B into operation while the blocked jets are simultaneously brought to the flushing position and cleared by the flow of flushing fluid from inlet 9 to outlet 10A.  Two whistles only may be used, one operating at a time, or there may be two sets with two or more in each set.
