US Patent:

7245471, Jul 17, 2007

Filed:

Oct 29, 2003

Appl. No.:

10/696104

Inventors:

Michael Pollock - Troy MI, US
Fred Kahl - Grosse Ile MI, US

Assignee:

Edw. C. Levy Co. - Dearborn MI

International Classification:

H02H 3/20

US Classification:

361 915, 361159

Abstract:

A method and apparatus for protecting an energized inductive device such as an electromagnet from an open circuit, i. e. , the loss of the power source for the inductive device. A diode is connected across terminals of the inductive device such that when the inductive device is normally energized, the diode is reversed-biased. A spark gap enclosed in a housing is connected in series with the diode. An inert gas fills the housing. A resistance in the form of one or more resistors is in series with both the diode and the spark gap. Upon the sudden loss of supply to the energized device, the diode, the resistance and the spark gap form a path for the discharge of energy from the inductive device.

Appl. No.:

11/843904

Inventors:

Michael Pollock - Troy MI, US
Fred Kahl - Grosse Ile MI, US

Assignee:

Edw. C. Levy Co. - Detroit MI

International Classification:

B66C 1/00

US Classification:

701 29, 701 50, 294 655, 715771, 700 83

Abstract:

An apparatus for providing diagnostics of a work device includes an electric crane including an operator cabin and a derrick that supports a lifting magnet; a diagnostic panel disposed proximate the operator cabin; a device that provides one or more operating parameters associated with an operation of the electric crane; and a logic controller in communication with the device and diagnostic panel. The logic controller receives the one or more operating parameter. The diagnostic panel provides one or more quantifiable diagnostics of the electric crane and/or magnet according to the one or more operating parameters received by the PLC. A method is also disclosed.

Filed:

Feb 5, 2008

Appl. No.:

12/026125

Inventors:

Michael Pollock - Troy MI, US
Fred Kahl - Grosse Ile MI, US

Assignee:

Edw. C. Levy Co. - Detroit MI

International Classification:

B66C 1/06
H02P 9/10

US Classification:

294 655, 361144, 414606

Abstract:

A method for operating an electric crane, comprises the steps of activating a magnet controller to cause a current to flow through a magnet for creating a magnetic field about the magnet for securing a load to the magnet, receiving a feedback input value at a logic controller from a device associated with the electric crane, in response to the received feedback input value at the logic controller, receiving a command value at the magnet controller from the logic controller, and in response to the received command value at the magnet controller, modifying the current flow from the magnet controller to the magnet to change the magnetic field about the magnet. A system is also disclosed.

International Classification:

B65D 90/62
B65F 1/16
B65D 90/66

Abstract:

A receptacle is provided for holding a quantity of solid material. The receptacle includes a container having an open end, and a gate operably connected to the container so as to be rotatable to a closed position structured to prevent solid material from exiting the container through the open end. The gate includes a locking arm mounted thereon. A latching mechanism is operably connected to the container and includes a latch rotatable to a latched orientation structured to contact the locking arm to prevent the gate from being rotated out of the closed position. The locking arm is structured to move rearwardly and upwardly during rotation of the gate out of the closed position. The latch is structured so that contact between the latch and the locking arm when the latch is in the latched orientation prevents rearward and upward movement of the locking arm.
