The study presents an attempt at increasing the effectiveness of the crushing process through the application of a new original crumbling system. In the process of crushing materials, friction is present in many crushers as extremely significant or even dominating factor. The proposed construction solution is characterized by the occurrence – always on one of the working surfaces – of the static friction factor, and thus a friction that is greater than the kinetic friction.
The problem of Hungarian identity is one of the themes of Stanisław Vincenz’s essays written at the time of the Second World War. Inspired by Wincenty Pol’s thinking about relationship between the sense of geographical place and literature, he decided to explore the ‘general impact of landscape’ and in particular identify the place that would convey the essence of ‘Hungarianness’. The article looks at various aspects of this problem in Vincenz’s essay ‘Landscape – the background of history’ in the context of his other essays in which the idea of place is discussed. In effect, the article lays down a theoretical formula of indeterminate spots in modern literature. The indeterminate spot possesses six constitutive features: changeability and transmutability; fuzzy borders; shifty positioning between utopia and atopia; great semantic potential; the experience of place is involved in irreducible inconsistencies but rests on a solid ideological foundation.
