Abstract: A device including one or more nozzles having a tubular fiber spinning needle and method for producing non-toxic polymer fibers and microfibrous and nanofibrous polymer materials made thereof on a small to large scale using a wide range of synthetic polymers and bio-based polymers. The device and method enable continuous in-line production of polymer fibers at a high fiber production rate energy efficiently and safely. The increased polymer fiber production rate is achieved by the at least one nozzle that enables a centrifugal force acting upon the tubular fiber spinning needle causing rotational motion of the tubular fiber spinning needle and higher polymer injection rates per nozzle.

Abstract: A coin-sorting machine designed to separate non-standard coins, e.g., foreign currency, from standard coins of the national currency to be sorted, and to collect these non-standard coins in a special tray, comprises a plurality of feeler levers, each disposed adjacent to respective detectors intended to sort the standard coins and each controlling an associated thrust member. The standard coins are deflected into respective sorting receptacles, while each non-standard coin is struck in the middle by one of the thrust members and flung over the mouths of the sorting receptacles into the special tray. Each thrust member associated with a feeler lever may be made in one piece with an ejector associated with the preceding detector and take the form of an ejecting nose contiguous with a deflector surface of that ejector.
