Latest Patents
Ralph W. Gruetzmacher holds a patent for a "Magnetizing current supply for magnetic particle inspection with SCR's." This invention involves magnetizing current supplies designed to provide current for magnetizing parts in a magnetic particle inspection system. The system utilizes silicon-controlled rectifiers (SCR's) connected in circuit with a three-phase voltage step-down transformer. This configuration allows for precise control over the duration and magnitude of the magnetizing current. In one implementation, six SCR's are connected between the magnetizing apparatus and the terminals of three center-tapped secondary windings of a three-phase voltage step-down transformer. The SCR's are operable to rectify current and are linked to a phase control circuit that manages the firing times of all SCR's, thereby controlling the magnitude of the magnetizing current.
