  1. Aparat pentru determinarea unor caracteristici fizico-mecanice ale materialelor dentare Ioanid Emil Ghiocel, Avram E., Luca C. România Brevet RO Nr. 116680 Realizarea unui aparat pentru determinarea unor caracteristici fizico-mecanice ale materialelor dentare cum ar fi timpul de lucru si de intarire Aparatul permite ca proba plasata intr-o caseta termostata la 37C sa fie adusa in contact cu un poanson inaintea inceperii fiecarei testari cu ajutorul unei placute, a unui tampon de presare si a unui electromagnet al carui miez mobil este cuplat mecanic cu poansonul si cu tija palpatoare astfel incat la deconectarea electromagnetului, o greutate apasa poansonul in proba pe o adancime ce reprezinta gradul de intarire. -asigura termostatarea probei la 37C; -timpul de actiune al poansonului este controlat; -poansonul este in contact cu proba inaintea inceperii fiecarei determinari; The apparatus allows the assay at 37C to be brought in contact with a mandrel before each test with the help of a plate, a pressing buffer a an electromagnet; the mobile core of the electromagnet is mechanically joined with the mandrel so at the electromagnet disconnection, a weight press the mandrel onto the assay on a depth representing the hardening degree. Experimental model.
