Patent number: 9190200Abstract: A method and system for moving magnetic material includes an electromagnet wherein known problems associated with DC power circuit interruptions are substantially reduced. The system includes a generator coupled to an electromagnet, the generator being powered by a power supply through a first set of contactors which are configured to open and close a first circuit between the power source and the generator coupled to the magnet to start and stop a lifting sequence, wherein the first circuit includes a first bridge rectifier, a reactance element, and a first resistance element.Type: GrantFiled: September 9, 2013Date of Patent: November 17, 2015Assignee: EPHAUGH, INC.Inventor: John Samila

Patent number: 8331067Abstract: An apparatus and method for providing ground fault protection to a lifting device utilizing an electromagnet and powered by a generator. The apparatus and method rectifies an AC voltage emanating from the generator source and monitors unsafe operating conditions of the generator's circuit wherein operation of the lifting device is ceased when predetermined electrical operating parameters are exceeded.Type: GrantFiled: December 29, 2009Date of Patent: December 11, 2012Assignee: Ephaugh, Inc.Inventor: John Samila

Patent number: 8068325Abstract: A method and apparatus for moving magnetic material includes an electromagnet for lifting the magnetic material where upon its release, the residual magnetic flux of the lifted magnetic material is reduced. The apparatus includes a generator coupled to the electromagnet. The generator includes a control input and an armature having a voltage output. A controller has an output coupled to the generator's control input and armature voltage output, whereupon receiving a release material signal from an operator interface panel to release the magnetic material from the electromagnet, the controller transmits a plurality of control signals, one of which is at least partially dependent upon the duration of a previously transmitted control signal, to effectively alternate the polarity and reduce the magnitude of the magnetizing force of the electromagnet.Type: GrantFiled: August 9, 2010Date of Patent: November 29, 2011Assignee: Ephaugh, Inc.Inventor: John Samila

Patent number: 7795747Abstract: A method and apparatus for moving magnetic material includes an electromagnet for attaching and detaching the magnetic material where upon release of the magnetic material, the residual magnetic flux of the released magnetic material is reduced. The apparatus includes a generator coupled to the electromagnet. The generator includes a control input and an armature having a voltage output. A controller has an output coupled to the generator's control input and an input coupled to the armature voltage output, whereupon receiving a lift or release material signal from an operator interface panel to lift or release the magnetic material from the electromagnet, the controller transmits a control signal that is at least partially responsive to the voltage output of the armature to effectively maintain the voltage output of the armature to a set-point value.Type: GrantFiled: December 17, 2007Date of Patent: September 14, 2010Assignee: Ephaugh, Inc.Inventor: John Samila
