  • Patent number: 4144708
    Abstract: A clock has a clock face in the form of an axially symmetric solid, e.g. a sphere, a cone or a cylinder. Clock hands extend around the clock face following a helical path, and time-indicating markings are arranged on all the surfaces of the face. It is therefore possible for a complete set of these markings to be seen from any direction relative to the clock face. The hands are normally driven by a conventional clock movement, there being an hour hand and a minute hand. However, it would be possible in some applications to have only a single hand, e.g. a minute hand, and to drive the clock face relative to the hand. The markings are arranged along helical paths, corresponding to the helical shape of the hands.

  • Patent number: 4145618
    Abstract: A high voltage power supply system for energizing a static inverter, in which an auxiliary circuit provides a source of reserve energy to sustain inverter operation during periods of power interruption. In the auxiliary circuit, there is provided a capacitance normally charged from the source of power (catenary) via a resistance whose ohmic value assures a slow rate of charge to avoid blowing the input fuse in the event of a short in the auxiliary circuit capacitance and to permit use of the desired capacitance with a reduced voltage rating. A diode arrangement statically connects the higher of the catenary voltage or the stored energy reserve of the auxiliary circuit to the inverter.

  • Patent number: 4145640
    Abstract: Variable pulsing of a dc source without change of polarity is used for lossless control of the speed of a compound dc motor. The pulsed dc supply is fed in series through the series field winding, armature and reversing switch system and the shunt field winding has one terminal connected to the pulsed dc source and its other terminal connected respectively through two conductively poled diodes to the opposite terminals of the armature winding. Two anti-kickback devices are also provided, one of which operates during reverse-current braking. The reversing switch system has two independently actuatable single-pole double-throw switches of which the respective arm contacts are connected to the ends of the armature winding, one fixed contact of each of these reversing switches being connected to the series field winding and the other pair, likewise connected together, being connected to one terminal of the dc supply.

  • Patent number: 4144789
    Abstract: An amplitude curve generator for use with an electronic organ or the like to control the musical shape of an audible tone. The generator utilizes a simple binary down counter driven from a clock source to produce a sequence of decreasing binary numbers that approximate the relative amplitudes of equally spaced points along an exponential decay curve. The count condition of the least significant bits of the counter correspond to the mantissa of number expressed in binary floating point notation. The most significant bits represent the power. The bits of the mantissa are transferred to a parallel shift circuit and shifted a number of times determined by the bits of the power to convert the number in the counter to fixed point notation. The output of the shift circuit is used to control the envelope amplitude of a musical tone. The output may be subtracted from one (2's complement) to produce a set of values that correspond to an exponential attack curve rather than a decay curve.

  • Patent number: 4144788
    Abstract: The bass note generation system provides one of several different types or styles of bass-line accompaniment for the organist. A chord pattern detector receives signals on keying lines corresponding to keys depressed by the instrument player and attempts to recognize a normalized chord pattern. A counter tracks the operation of the chord pattern detector and provides an output corresponding to the alphabetic note of any recognized chord. If the chord pattern is recognized, the output of the detector and the output of the counter address a normalized and preprogrammed bassline pattern memory. The digital value of the bass note stored in the memory and the outut of the counter are serially added to transpose the normalized bass note to the appropriate musical key and applied to a decorder-keyer circuit at selected time intervals in a musical measure for providing a precomposed musical bassline output.

  • Patent number: 4143509
    Abstract: A time-keeping system of the type having an electromechanically driven, analog-type time display, has a purely electrical integral hour reset feature. The system comprises an analog time display including hour and minute hands driven through a mechanical transmission by a fast-response electromechanical motor. A stable oscillator generates a high frequency time base signal. A chain of frequency dividers coupled to the oscillator develops a time-keeping signal at a minute-related frequency for driving the analog time display in a normal time-keeping mode, and for developing hour reset pulses at a frequency much higher than one pulse per second for driving the analog time display during an integral hour reset operation.

Detecting circuits for detecting one of the DC power outputs which is being consumed are provided to apply to a control signal generator the output of one of the comparing circuits which is corresponding to the DC power output detected by the detecting circuits. The control signal generator provides a control signal to the single power control circuit to stabilize the voltage of the DC output which is being consumed.

The first cam is integral with a co-axial star wheel which is driven by a second cam having both a hook and an adjacent shoulder that advance the star extensions. The second cam is driven by the hour wheel.

  • Patent number: 4142437
    Abstract: An envelope circuit for a keyboard type electronic musical instrument having a damping and sustain characteristic. The circuit has a keyswitch operated in association with the actuation of a key on the keyboard of the electronic musical instrument to connect a power supply to a voltage responsive circuit for producing a decreasing volume output tone. A sustain circuit is coupled to the voltage responsive circuit for sustaining the operation of the voltage responsive circuit and is connected through a blocking diode to a sustain switch common to all the envelope circuits in the musical instrument. The sustain switch is connected in the sustain circuit for bypassing the voltage supplied thereto from a time constant circuit when the sustain switch is closed for making the sustain circuit inoperative to deenergize the voltage responsive circuit, whereby the voltage responsive circuit continues to produce an output tone independently of how the keyswitch is restored to its initial position.
