    摘要: Methods for controlling the in-feed and discharge rates of materials flowing into and out of a mixing process where one priority is to achieve a target mixture flow rate from the mixing process and another priority can be to achieve a target value for a mixture property. Actuators can be operated to control material in-feed rates, the mixture composition, and discharge rate, and can maintain a hold-up of the mixture in the mixing process. A total flow rate controller provides a control signal to a controller acting on the discharge rate and a controller acting on the in-feed rates. The mixture discharge flow rate can be automatically reduced from its desired target when the commanded rate of at least one of the materials exceeds its available supply rate as inferred from an inability to maintain the targeted value for the mixture property.

    摘要: Additives are blended with a stream of liquid, for example of diesel fuel, by injecting at least two different additive compositions into the stream, and adjusting the rates of injection and the relative proportions of the injected additive compositions. This enables the consumption of additives to be minimized while enabling desired fuel characteristics to be maintained despite variations in the characteristics of the untreated liquid. The rates of injection may be adjusted by an automatic controller (32) in response to signals from sensors (28, 30) representing characteristics of the liquid before and after treatment.

    摘要: An ultrasonic system for homogenizing a sample includes an ultrasonic transducer and a control system. The transducer includes a horn or other probe that oscillates to produce cavitation in the sample and a converter that drives the horn through its oscillatory motion. The control system includes a closed-loop amplitude-control configuration and process. In particular, the control system includes a user interface, a controller, and a high-frequency driver, all connected together in a closed-loop configuration for enabling amplitude-control feedback. Control software includes programming for the closed-loop amplitude-control process including receiving a user-inputted desired amplitude of oscillatory horn motion, driving the transducer at a corresponding power level, determining the actual amplitude of oscillatory horn motion, and automatically adjusting the power level to the transducer to maintain the desired amplitude during operation of the ultrasonic system.
