Abstract

Μέθοδος δια της οποίας ένα μίγμα δύο ή περισσοτέρων διακεκριμένων λεπτομερών υλικών, όπου έκαστον των αναφερθέντων υλικών έχει διαφορετικόν συντελεστή τριβής ολισθήσεως είναι δυνατόν να διαχωριστούν δια χρησιμοποιήσεως μεθόδων οι οποίαι επωφελούνται διαφορών ταχύτητος προκαλουμένων από εφαρμογή μιας δυνάμεως εις το αναφερθέν μιγμα προς δημιουργία κινήσεως του αναφερθέντος μίγματος επί μιας επιφανείας αναλόγως του συντελεστού τριβής ολισθήσεως αυτού. Αποκαλύπτονται επίσης διάφορες συσκευές προς διεξαγωγήν των διαχωρισμών. ωA method by which a mixture of two or more distinct details, each of which has a different sliding coefficient of friction, can be separated using methods that benefit from differences in velocity caused by the application of a mixture of forces to the mentioned. on a surface depending on its sliding friction coefficient. Various devices are also revealed to perform the separations. ω
