Abstract

Przedmiotem zgłoszenia jest przyrząd do badania efektu Mojżesza w materiałach granulowanych, mający zastosowanie w laboratoriach naukowych, zwłaszcza fizycznych oraz do celów edukacyjnych. Przyrząd do badania efektu Mojżesza w materiałach granulowanych zawiera głośnik elektrodynamiczny mający stożkową membranę drgającą i stalową zworę (3). Oś głośnika elektrodynamicznego i kierunek drgań stożkowej membrany są skierowane pionowo, zaś dolna powierzchnia stalowej zwory (3) jest przyklejona do podstawy (4) w kształcie prostokątnej, poziomej płyty. Do stożkowej membrany jest przyklejony dolny brzeg tulejki skierowanej pionowo i umieszczonej współosiowo ze stożkową membraną, zaś do górnego brzegu tulejki jest przyklejona płytka dolna (6) w kształcie prostokąta skierowana poziomo i do przeciwległych, krótszych boków płytki dolnej (6) są przyklejone dolne boki płytek bocznych (7, 8) skierowanych pionowo i do górnych boków płytek bocznych (7, 8) są przyklejone krótsze boki płytki górnej (9), też skierowanej poziomo. Płytki boczne (7, 8) i płytka górna (9) również mają kształt prostokątów i zespół płytek (6, 7, 8, 9) tworzy prostokątną ramkę. Do górnej powierzchni płytki górnej (9) jest przyklejony pierścień (10) skierowany poziomo i zaopatrzony we wkręt (11) mający radełkowany łeb i wkręcany w kierunku radialnym w nagwintowany otwór w pierścieniu (10), przy czym wkręt (11) jest wykonany z metalu nieferromagnetycznego, korzystnie z mosiądzu.The subject of the application is a device for testing the Moses effect in granular materials, applicable in scientific laboratories, particularly physics laboratories, and for educational purposes. The device for testing the Moses effect in granular materials comprises an electrodynamic loudspeaker having a conical vibrating diaphragm and a steel armature (3). The axis of the electrodynamic loudspeaker and the direction of vibration of the conical diaphragm are directed vertically, and the lower surface of the steel armature (3) is glued to a base (4) in the shape of a rectangular, horizontal plate. The lower edge of a vertically oriented sleeve coaxial with the conical membrane is glued to the conical membrane, while a horizontally oriented rectangular lower plate (6) is glued to the upper edge of the sleeve. The lower sides of the vertically oriented side plates (7, 8) are glued to the opposite, shorter sides of the lower plate (6), and the shorter sides of the horizontally oriented upper plate (9) are glued to the upper sides of the side plates (7, 8). The side plates (7, 8) and the upper plate (9) are also rectangular, and the assembly of plates (6, 7, 8, 9) forms a rectangular frame. A ring (10) is glued to the upper surface of the upper plate (9) and is oriented horizontally and provided with a screw (11) having a knurled head and screwed in a radial direction into a threaded hole in the ring (10), the screw (11) being made of a non-ferromagnetic metal, preferably brass.
