This study was devoted to verifying the performance of various configurations a winged chisel plough (WCP) in soil bin. The new tool assessed at three wing depths (5, 10 and 15 cm), bend angles (10, 20 30 °), rake (7.5, 22.5 °) with replications using completely randomised design constant depth speed cm 1 m·s–1, respectively. draught vertical forces, disturbed upheaved areas plus efficiency loo...

The technological scheme implementing machine engraving on a mineral and facsimile transfer of the halftone image from the personal computer is offered. The dot (microstroke) image is formed by a pulse system together with an electromechanical converter, such that the integral optical density of separate fragments equals optical density of the same fragments of the initial image. Structural con...
