  • Publication number: 20240060474
    Abstract: A hydraulic continuous variable transmission is provided to connect a wind turbine and a generator. The hydraulic continuous variable transmission has a primary paddle wheel and a number of secondary paddle wheels for macro speed control. Also provided are pneumatic paddle wheels for micro speed control. A controller is included that measures AC electrical characterized output to load or line for speed control.

  • Patent number: 11837863
    Abstract: A method and apparatus provide an improved way to monitor a circuit for deterioration and obtain an advance warning of the deterioration so that action can be taken before the circuit breaker may trip for the circuit. The method establishes a baseline for the circuit, including monitoring the zero crossing point for the voltage and current for the circuit. In operation, the circuit is monitored using the zero crossing point and this information is compared to the baseline to determine if a change has occurred. The baseline information establishes thresholds that signify that the circuit is deteriorating so that the appropriate signal can be provided so that an appropriate action can be taken, interrupt the circuit, take remedial action, etc.

  • Publication number: 20220403285
    Abstract: An apparatus and method of use employs a multiple displacement evacuation tank and a cavitation apparatus. Heated fluid from the cavitation apparatus is used to treat a plant material to obtain a purified oil product therefrom. The cavitation apparatus output is used to both heat the multiple displacement evacuation tank contents and supply a feed to the multiple displacement evacuation tank for oil product manufacture. The fluid is preferably a lipid emulsion and the plant material is preferably a hemp material that allows for recovering of the cannabinoids therefrom.

  • Patent number: 10848139
    Abstract: A method of monitoring the condition of a circuit comprises establishing a known baseline signal for a type of circuit (each is somewhat different) and defining these characteristics in terms of the lead and trailing edge angular components (@ zero crossing point), the voltage (amplitude), and the period (time length) of the waveform. Ideally, the angular component of the square wave should be vertical, or at 90 degrees to x-axis. The baseline non-regular square wave that is composed of current, voltage, any harmonic thereof, or the combination of these signals which best indicate predictive measurement attributed to the type of circuit being monitored. Future wave forms indicate the rate of decay based upon the aggregated angular, amplitude, and period components of the zero-crossing points when compared to the baseline signal and/or prior waveform of the observed specific splice. The rate of decay can help determine the life expectancy of the circuit.

  • Patent number: 10240774
    Abstract: A fluid cavitation apparatus includes a housing, an external rotor with cavitation bores in an outer surface thereof, and a motor for rotating the external rotor. An inner surface of the housing is spaced from the outer surface of the external rotor to create a fluid cavitation zone. The inner surface of the housing is configured with a spiral shape and tunnel zone to enhance the thermal transfer characterisitics of the fluid for heating, cooling, and purification. A control system to facilitate proper motor speed, and fluid behavior to enhance the cavitation process.
