Abstract: The invention relates to nonferrous metallurgy and may be suitable for controlling the feed of alumina to electrolytic cells for producing aluminum to maintain the alumina concentration in the electrolytic melt equal or close to the saturation value. To maintain the alumina concentration within the set range, reduced voltage U or pseudo-resistance R is measured. The measured values are recorded at fixed time intervals, underfeeding or overfeeding phases compared to a theoretical alumina feeding rate during electrolysis are formed, whereas the duration of underfeeding phases is selected depending on the alumina concentration in the electrolytic melt, and the duration of overfeeding phases is determined according to the change of one or more electrolytic cell parameters being recorded: reduced voltage, U, pseudo-resistance. R, rates of reduced voltage, dU/dt, pseudo-resistance, dR/dt, change.

Abstract: An apparatus and method are provided for a drone elimination muffler to attenuate drone exhibited by engine exhaust systems. The drone elimination muffler comprises a hollow canister having a length and a diameter, and a tuned port comprising a first end connected to the canister and a second end connected to the exhaust system.

A valve is configured to switch the drone elimination muffler between a closed state in which the exhaust system operates without acoustic influence due to the drone elimination muffler, and an open state in which the drone elimination muffler directly influences the acoustic properties of the exhaust system.

Abstract: An apparatus for operating a hand chain of a hand chain hoist. A housing forms a void through which a hand chain of the hand chain hoist moves in either a lifting direction or a lowering direction, to lift or lower, respectively, a load corresponding to the hand chain hoist.
