Abstract: A sample transfer apparatus atomizer connected via tube to a sample receiver for micro-sampling. The sample receiver has a funnel-shaped upward opening and is connected to the tube at the base of the funnel. A control unit controls the apparatus to make sure that the sample injected into the sample receiver will be so positioned in the tube that a quantity of solvent is positioned nearer to the vaporizer than the sample, and preferably another quantity of solvent is positioned nearer to the side of the sample receiver relative to the sample. The presence of solvent in the tube positioned nearer to the vaporizer than the sample delays the sample being sucked by the vaporizer, this preventing interruption of the sample flow in the tube and making the atomic absorption waveform more stable.

Abstract: In the production of reduced pellets such as reduced iron pellets by the grate-kiln system for firing, a distributor and a belt conveyor provided with a weighing machine are arranged between a sieving machine that sieves produced green pellets to predetermined grain sizes and a travelling grate of a pretreatment furnace. The weight of green pellets fed from said sieving machine through said distributor onto said belt conveyor is continuously measured on said belt conveyor by means of said weighing machine, and a signal indicative of the measured value is fed back to said distributor. Said distributor operates in response to said signal and regulates the supply of green pellets so that the supply of green pellets to said belt conveyor, hence the supply of green pellets to said grate is kept constant. Said distributor is of such a construction as will not crush green pellets.
