Invention refers to a dental furnace for prosthetic dentures. The furnace comprises a firing chamber, wherein a prosthetic denture can be notably placed, particularly in a muffle between the furnace bottom and top; what is also provided is a temperature sensor connected to a control unit of the dental furnace, arranged outside the firing chamber and having a detection sensor extending outside the firing chamber. The temperature sensor is additionally configured in the form of a proximity sensor; the furnace has particularly at least one auxiliary sensor for detection and identification of an approaching object and/or user of the dental furnace. |

Device for high-temperature test of metals and alloys Device is intended for high-temperature test of metals and alloys in vacuum or in gas medium. The device includes a detachable pressure-tight chamber consisting of top and bottom parts attached to each other through a flange connection, a melting pot with a metal or alloy test specimen arranged in it, pipelines for pumping the air out of the chamber and supply of gas to it, a temperature metre and an induction heater. In the top part of the detachable pressure-tight chamber an arrangement is made for a cooled box-like element with a detachable cooled plate fixed on it, calibrated as to weight and made from alloyed heat-resistant steel. The melting pot is located inside the detachable pressure-tight chamber. The cooled box-like element is connected via pipelines to a cooling substance supply and circulation unit in the above element. |
