The invention relates to a water feeding head suitable for the water supply f row crops, first of all vineyards and orchards. Its use enables the drop feed type irrigation of loose soils so far unsolved. The water feeding head is assembled from two parts, i.e. from the body releasably connected e.g. with thread to the pipeline and from the replaceable nozzle fitted to the body. The nozzle is provided with one or several orifices discharging the water by drop feed method, and the heads are arranged along the pipeline at a distance from each other in accordance with the transmissivity of the soil.

A process for reducing the inclusion content of steels and refining their structure which comprises the steps of subjecting molten steel containing inclusions to a pressure of at least 1 atm; removing inclusions from the molten steel by introducing therein at said pressure an inclusion-removing alloy containing calcium or magnesium; and thereafter applying vacuum to the molten steel to evaporate residual calcium or magnesium from the steel.

The invention relates to a watering head for the drop feed irrigation mainly of orchards with impermeable soil. It consists of two main parts, i.e. the body connected to the watering pipeline, and the replaceable feeder unit mounted on the body. Occasionally the body and the feeder unit are constructed from one piece. The feeder unit is a prism, or body of rotation extending in the longitudinal axis, the interior of which is provided preferably with a spatial spiral polygonal braking duct reducing the flow velocity of the irrigation water. One end of the braking duct leads into the part, e.g. receiving sleeve pulled over the body--suitable for connection of the feeder unit and body to each other, while the other end is developed as a drop feed orifice for discharge of the irrigation water.
