Abstract: A method and apparatus for generating electricity from a generator driven by the flow of fluid flowing from a fluid producing well. A fluid driven motor is positioned in the pipeline adjacent to or above the well head such that the fluid passes through the motor to turn the motor shaft to drive the generator. By controlling the electrical load connected to the generator, the force required to drive the motor and thereby the pressure reduction across the motor can be controlled. The electricity produced by the generator may be used to heat the fluid in the pipe to prevent freezing of the fluid. The electricity can be utilized to heat the emulsion in an emulsion separator dehydrator for separating gas, water, and oil prior to its introduction into the pipeline. Separate motor may be utilized for gaseous fluid and liquids. Where the well produces both gas and liquid a separator is employed to separate the gas and liquid.

Abstract: An armature of an electric motor for an elevator car is controllably driven by a three-phase source through a semiconductor converter controlled with a difference between a command and an actual car speed signal. A relay for sensing a ripple current from the converter is serially connected to a tuned filter across the armature. When a break occurs anywhere in a circuit with the motor armature, the sensor relay is deenergized and connects an emergency braking circuit across the armature. Alternatively the sensor relay may be connected via the filter to a reactor connected to the converter.

Abstract: In an electronic musical instrument, the amplitudes of respective partial components constituting a composite waveshape at successive sample points are produced, these amplitudes are multiplied, at regular time intervals individually by coefficients each being associated with corresponding partial components to obtain the amplitudes weighted, these weighted amplitudes being accumulated successively to obtain the net amplitudes weighted of the composite waveshape for each sample point. The net amplitudes are converted to a musical sound by sounding means. The coefficients are repetitively calculated at another regular time intervals, each of which being longer than the foregoing regular time interval, by implementing the algorithm of a certain function of time, as the multiplications are carried out.

Abstract: This relates to an electric power generating system particularly adapted for use in locals where there is an absence of a water supply with sufficient elevation to supply the required power for an electrical energy generating system, or the water supply is insufficient for the required generating system. The deficiency is overcome in part by providing an elevated water supply reservoir and a system of gravity actuated water powered pumps for utilizing the discharge of the generating system to pump at least a portion of the discharge to the elevated reservoir. It is further proposed to utilize a pumping system of the wave motor type for pumping relatively available water at sea level to the elevated water reservoir. It is also proposed to provide a split stream of water from an elevated water supply to two generators at different elevations with the discharge from the uppermost generator being recombined with the other portion of the split stream for introduction into the generator at the lower level.

Abstract: In infrared spectroscopy utilizing an interferometer, position stepping of the optical path difference in the interferometer must be accomplished quite rapidly in response to a drive signal applied to a moveable mirror in the interferometer which is proportional to the offset distance desired from the previous null point. As the mirror moves in response to this drive signal, effectively getting closer to the new null point, the drive signal is gradually reduced, in response to detected reference laser fringes. At the new null position, the drive signal will effectively be zero. A binary up/down counter drives a digital/analog converter (DAC). The output from the DAC is supplied to the mirror moving means. The fringes generated by a reference laser are detected as the mirror moves, causing the up/down counter to be decremented to its null count, thereby reducing the output of the DAC, as the mirror moves towards its new null position.

Abstract: An electronic timepiece uses a dynamic type shift register, as a time count circuit, which has a plurality of memory sections corresponding to an equal number of time count units and a cycle number memory section arranged such that it is preceded by said plurality of memory sections. An adder and shift memory unit are serially connected to the shift register to provide a shift circulation circuit and the shift circulation is effected by an oscillation signal from a reference oscillator. The adder adds [1] to the contents of the cycle number memory section for each data shift cycle of the shift register. Each time the count value of the cycle number memory section reaches a predetermined cycle number, the count value of a smallest time unit is counted one step. In this way, a carry is propagated to the subsequent large time unit memory sections according to the data shift circulation cycle of the shift register.

Abstract: A plurality of waveshape memories are provided for storing the sampled values of one cycle sinusoidal wave as the fundamental frequency, two cycle sinusoidal wave as the second harmonic, . . . and m cycle sinusoidal wave as the m-th harmonic and, in addition thereto, of harmonic-abundant complex waves such as a triangular wave, a sawtooth wave and a rectangular wave. These waveshape memories are read at the same reading rate. The read out sinusoidal waves and triangular, sawtooth and rectangular waves are controlled in their relative levels in accordance with the tone-color of an intended musical tone wave shape. The sinusoidal waves and the triangular, sawtooth and rectangular waves are thereafter synthesized to produce a desired tone-color wave shape. Since the triangular, sawtooth and rectangular waves contain abundant harmonic components, many kinds of musical tones containing abundant harmonic components can be produced despite a limited number of waveform memories.

Abstract: Improved speed dictation apparatus for controlling the speed of an elevator car in which the deceleration of the elevator car is brought into conformity with that which would be provided by a distance controlled signal notwithstanding the continued application of a time controlled signal and the deceleration is made consistent regardless of the length of trip by controlling the speed of the car in accordance with the distance controlled signal before the car starts to decelerate and by controlling the conformity process with a dischargingcapacitive circuit which at the time the conformity process begins is charged to a voltage signifying the difference between the actual speed being dictated to the car and the speed the distance controlled signal is then dictating.

Abstract: During the acceleration of an elevator car frequency modulated clock pulses are counted up by a first counter to generate a command speed pattern. A second counter similarly generates a second speed pattern identical in shape to and delayed a predetermined time relative to the command speed pattern. A randum access memory successively stores theoretical distances of movement of the car due to the command speed pattern suitably corrected and the second speed pattern as a distance-to-speed function. When and after both patterns first equal each other, a command deceleration pattern is generated to follow objectives or the distance-to-speed function. Once the command speed again equalled the objective, the intact distance-to-speed function is used as a command deceleration pattern concerning residual distances to a stop floor.
