Definitions

  • This invention relates to a circuit arrangement using a transfluxor for the storage of analog values.
  • it relates to circuits using a transfluxor for which the setting and blocking currents are supplied in the form of pulses,
  • the present invention is an analog signal storage arrangement which comprises transfluxor means having a setting winding and an output winding, which transfluxor means store an analog value corresponding to the number of setting pulses applied to said setting winding and furnish an output signal corresponding to the so-stored analog value at said output winding. Further, self-excitation circuit means are connected between said output winding and said setting winding for furnishing said setting pulses to said setting winding in correspondence to external activation, thereby causing the storing of said analog value.
  • the arrangement in accordance with this invention further has additional self-excitation circuit means connected between said output winding and the blocking winding of said transfluxor means. Upon additional external activation, said additional self-excitation circuit means cause blocking pulses to be applied to said blocking winding, thereby decreasing said stored analog value.
  • the self-excitation circuit means and the additional self-excitation means comprise first circuit means furnishing a first signal having an amplitude corresponding to the rate of change of amplitude of said output signal, and amplifier means amplifying said first signal.
  • the first circuit means in a preferred embodiment, may comprise a rectifier and a differentiating circuit.
  • the amplifier means comprise a plurality of amplifier stages. One of these amplifier stages receives an operating voltage only when a stored analog value is to be changed. This operating voltage is thus applied by external activation and may be applied to integrating means prior to application to the stage to serve as operating voltage thereof.
  • the operating voltage for one of the amplifier stages is applied by means of a first switch to the self-excitation circuit applying pulses to the setting winding and through a second switch to the amplifier stage in the self-excitation circuit supplying the blocking winding. Because an analog value once stored in the transfluxor may be maintained indefinitely, the arrangement of the present invention is particularly useful when used in conjunction with remote control means for controlling communication equipment.
  • the drive winding of the transfluxor be controlled by pulses derived from the horizontal deflection transformer of the television receiver.
  • volume, tone, brightness, contrast, hue, color saturation and station selection in either radio or television receivers all lend themselves particularly well for remote control by a circuit arrangement of the present invention.
  • the additional pulse generator is no longer required.
  • the feedback circuit may be used to effect a change in the analog value stored in the transfluxor which varies in direct proportion to time. By the insertion of other active and/or passive circuit elements into the feedback circuit, the change in analog values stored in the transfluxor may also be caused to vary as other functions of time.
  • a further pulse generator may be saved by use of the pulses from the horizontal deflection transformer of a television receiver as driving pulses.
  • FIGURE shows a circuit arrangement in accordance with the present invention.
  • one of the switches 2, 3 is closed when it is desired to change the value stored in the transfluxor in a increasing and decreasing direction respectively.
  • one of these switches is held closed until the desired analog valve' has been reached.
  • switch 2 is closed. Closing of switch 2 causes a positive 'voltage to be applied to integrating means comprising a resistance 4 and a capacitor 5.
  • the voltage across capacitor 5 is applied through a further resistance to the collector of a transistor 11 whose emitter is connected to ground and whose base is connected to one tap of a voltage divider connected between the positive supply side and ground.
  • the operating voltage for transistor 11 thus increases in correspondence to the time constant determined by the values of resistance 4 and capacitors.
  • the voltage applied to the collector of transistor 11 is also applied to the base of a transistor 12 whose emitter is connected to ground and whose collector is con-
  • the AC. output voltage is rectified by a rectifier 22 having a cathode connected to one terminal of the output winding and an anode connected to one terminal of a resistance 24 whose other terminal is connected to ground.
  • a filtering capacitor 23 Connected in parallel with resistance 24 is a filtering capacitor 23.
  • the common point of diode 22 and resistance 23 is denoted by reference numeral 28.
  • This voltage is differentiated by a differentiating circuit comprising a capacitor 13 connected to a resistance 14, thereby causing a negative voltage surge of amplitude corresponding to the rate of change of transfluxor output voltage to be generated at the common point of capacitor l3 and resistance 14.
  • This common point is connected to the base of a transistor whose emitter is connected to ground and whose collectoris connected to a'second' tap of the voltage divider furnishing the base voltage for transistor 11.
  • Transistor 10 amplifies the voltage surge applied to its base.
  • the soamplified surge is again amplified by transistor 11, thereby causing transistor 12 to block.
  • the blocking of transistor 12 causes an interruption of the currentv through setting winding 18.
  • the output voltage at terminal 28 therefore remains constant, eliminating the voltage at the output of the differentiating circuit. This in turn causes transistor 10 to become conductive,
  • switch 3 is closed causing the above-described cycle to be implemented in conjunction with blocking winding 19 of transfluxor 17.
  • the switch 3 when closed, causes negative voltage to be applied to additional integrating means comprising a resistance 6 and a capacitor 7.
  • the voltage across capacitor 7 is applied to additional amplifier means, denoted by reference numeral 9 in the FIGURE, in the same fashion as the voltage across capacitor 5 was applied to transistors 11 and 12 of threestage amplifier 8.
  • the driving voltage for three-stage amplifier 9 is supplied by means of an additional differentiating circuitcomprising a capacitor 15 and a resistance 16 in the same manner as the output of the differentiating circuit comprising capacitor 13 and resistance 14 was applied to transistor 10.
  • the transistors constituting amplifier stage 9 must be of opposite conductivity type to those utilized in amplifier 8. It is of course also possible to use a positive voltage and transistors of the same conductivity type.
  • the particular values chosen for the differentiating and integrating circuits (4-7 and 13-16) can serve to control the pulse width in the setting and blocking winding and further the rate of change of output voltage resulting fom the closing from one of the switches 2, 3.
  • the pulse widths and thus the voltage increments at the output winding can be maintained sufficiently small that the process may be considered a continuous process.
  • the invention may be used for storing stations in tuness associated with radio and television receivers.
  • the driving current for transtluxor 17 may be derived from the transformer furnishing the horizontal deflection pulses.
  • Terminal-27 in the FIGURE is connected to such a transformer.
  • This terminal is further connected to a capacitor 26 connected in series with a variable resistance 25 which is in turn connected to the driving winding 20 of transfluxor 17.
  • Resistance 25 may be adjusted to yield the most advantageous pulse shape.
  • switches 2 and 3 are connected to a receiver 1 through which they may be operated by means of wireless remote control.
  • Analog storage arrangement comprising, in combination, transfluxor means having a'setting winding, an output winding, a transfluxor output connected to said output winding and a transfluxor input connected to said setting winding, for storing an analog value corresponding to setting signals applied to said setting winding and furnishing an output signal having an amplitude corresponding to said so-furnished setting signals at said transfluxor output; and wireless remote control switch means connected to said transfluxor input for furnishing said setting signals'to said setting winding upon external activation, whereby said output signal at said transfluxor output varies in response to said external activation.
