  • Sterilizing apparatus
    Patent number: 4042805
    Abstract: Sterilizing apparatus is provided in accordance with the teachings of the instant invention wherein a programmed cycle of operation is initiated and maintained unless electrical failure occurs. According to one exemplary embodiment, upon activation and cycle initiation, a door to a sterilizing chamber is locked and a control relay is latched in an enabled condition. The enabling of the control relay energizes a heater disposed in a heating relationship to the sterilizing chamber and the heat generated within said sterilizing chamber is monitored by a sensor which selectively controls the heater to maintain a selected heat within the sterilizing chamber. When a predetermined temperature within the sterilizing chamber is detected a timer is initiated for the sterilization cycle selected.
