摘要： A system for regulating the viscosity of a fluid prior to atomization includes a temperature controller configured to adjust a temperature of a fluid flowing in a conduit prior to atomization of the fluid by an atomizer fluidly connected to the conduit and a sensor in communication with the temperature controller such that the sensor can provide an indicator to the temperature controller of a viscosity of the fluid flowing in the conduit prior to atomization. An adjustment to the temperature of the fluid by the temperature controller is based at least in part on the measured viscosity indicator of the fluid, a target atomization-viscosity of the fluid, and a coking temperature of the fluid.

摘要： Control circuitry utilizing first and second voltage sources and first and second circuits across such sources, one circuit having a first energizable element in series with a first diode arrangement and the other circuit having a second energizable element in series with a second diode arrangement. If the voltage difference from the sources is greater than a first value the first diode arrangement is conductive and the energizable element is energized, while if such voltage difference is less than a second value this second diode arrangement is conductive and the second energizable element is energized.

摘要： A soft-serve freezer operates in a first mode, with both the auger and compressor operating, and a second energy saving mode in which only the refrigeration compressor operates. The control circuit monitors the power level to the auger to control the consistency of the mix. When the mix achieves a selected consistency, the auger discontinues its mixing function. Signal lights are provided to indicate when it is necessary to actuate the auger to obtain the desired consistency prior to dispensing the product and indicate that the mix has achieved the desired consistency.

摘要： In a system for maintaining density of a printed color constant, a reading unit is connected with a unit measuring the reading signal. An amplitude measuring unit and a rated variable voltage source are connected with a comparator. The comparator is connected with a PID regulator, the signal of which is connected with a first adder which itself connects with a viscosity code setting potentiometer. The first adder is connected with a second adder connected to a viscosimeter. The signal produced by the second adder is sent to an amplifier connected with a command circuit for controlling mixer valves for ink and solvent. This command circuit can be locked or released by means of signals received from a level indicator in a tank. The command circuit also actuates a pump and a valve of a return circuit of the ink/solvent mixture. The system is employed for controlling and keeping constant color density of a print.

摘要： Liquid feeds from the upper reservoir to the lower refrigerated chamber where it is frozen on the walls. The scrapers and blades in the lower chamber scrape ice from the walls and keep the liquid/ice mix agitated. The slush is drawn off to be served. As the ice content increases, the load on the scraper drive increases. When the desired consistency is reached, the control shuts down the refrigeration. The control responds to torque and requires a sustained torque for a predetermined period to respond and shut down the compressor. The compressor is not restarted until the torque has dropped to a predetermined lower value.

摘要： A simple analogue control device for controlling chemical processes comprises a primary interfacing circuit, and analogue computer circuit, a memory-controller, and a process control circuit. The memory-controller circuit in its most specific aspect comprises a recorder-controller, a storage device which stores the output voltage from the recorder-controller, a switch between the recorder-controller and the storage device, and a timer circuit which sequentially opens the switch between the recorder-controller in the storage device, actuates the pen motor of the recorder-controller to allow the pen to take a new position in response to the input voltage signal into the recorder-controller, deactivates the motor establishing a new output voltage proportional to the input voltage signal and closes the switch to store the new output voltage.
