Filed:

May 10, 2002

Appl. No.:

10/143588

Inventors:

Douglas P. Cleereman - Greendale WI
William J. Mayer - Hales Corners WI
David S. Fisher - Brookfield WI

Assignee:

Rockwell Automation Technologies, Inc. - Mayfield Heights OH

International Classification:

H01H 4700

US Classification:

361189, 361166, 361192

Abstract:

An apparatus and method for monitoring main contacts and auxiliary contacts of a power contactor is disclosed. The apparatus includes four circuits, the first of which has an on state in which a coil of the contactor is energized, and an off state. The first circuit switches from the off state to the on state when a power source is electrically connected to the first circuit if an additional signal is also present, and then remains in the on state until the power source is disconnected. The second circuit prevents the additional signal from being received by the first circuit when the auxiliary contact is in a position indicating that one of the main contacts is welded. The third circuit causes the first circuit to be disconnected from the power source when the fourth circuit provides a signal indicating that one of the auxiliary contacts is welded.

International Classification:

H02H009/08

US Classification:

361 42, 361 43

Abstract:

International Classification:

E01D001/00

US Classification:

14 713, 14 711

Abstract:

A dock leveler assembly includes a base and a ramp that is pivotably movable under the influence of a biasing arrangement to a raised position. The ramp is lowered into engagement with a truck bed, preferably via a lip connected to the outer end of the ramp, and a holddown assembly maintains the ramp in a lowered position during loading and unloading of the truck bed against the force of a biasing arrangement that urges the ramp toward a raised position. The holddown assembly includes an extendible and retractable mechanism which is selectively fixed in position to maintain the ramp in a desired position. A “float” apparatus using a compression spring accommodates a certain amount of vertical movement of the ramp as the truck bed moves up and down during loading and unloading. A release arrangement enables the holddown assembly to be extended and retracted, and includes an automatic actuating arrangement that allows the mechanism to be extended upon application of a selected upward force to the ramp when the ramp is in a lowered position. The automatic actuating arrangement includes a flexible member such as a chain, and an adjustment arrangement for adjusting the inoperative position of the release member so as to control the degree of movement of the release member that is required in order to move the release member to the operative position from the inoperative position.

Assignee:

Rockwell Automation Technologies, Inc. - Mayfield Heights OH

International Classification:

H02H 3/00

US Classification:

361170, 361 42

Abstract:

An system and method are disclosed for isolating and grounding a load device, where grounding only occurs after the voltage(s) on the load device have been reduced to acceptable levels. The system includes power and grounding contacts, a sensing device, and a control device. The power contact determines whether a power line is coupled to a terminal of the load. The grounding contact determines whether the terminal is coupled to ground. The sensing device is coupled to the terminal, and the control device communicates with the contacts and sensing device. Upon a signal being provided to the control device, the control device causes the power contact to decouple the terminal from the power line and, upon the sensing device determining that a condition has been met concerning the terminal, the control device causes the grounding contact to couple the terminal with ground and a system indication light to be illuminated.

International Classification:

B65G 67/02

US Classification:

414401

Abstract:

A driveway truck restraint blocks the path of travel of an ICC bar at the back of a truck on a driveway at a loading dock to prevent forward travel of the truck away from the loading dock. The restraint is removably anchored to the driveway in non-cast-in relation without concrete around an encasing column depending downwardly through the driveway into the subgrade. A low profile is provided both above and below grade. A water dam is provide around a cable opening. Simplified, economical installation is provided.

International Classification:

F02M 1/02
F02D 41/06

US Classification:

123676, 12317918, 261 393

Abstract:

An internal combustion engine includes a muffler configured to reduce exhaust gas noise, a choke valve configured to control a flow of air in a carburetor, a thermally responsive element coupled with the choke valve and configured to move the choke valve in response to a temperature change in the thermally responsive element, and a thermally conductive member. The muffler has a housing defining an interior and an exterior. The thermally conductive member has a first portion positioned in the interior of the muffler in direct contact with the exhaust gases and extends through the muffler housing to the exterior of the muffler. The thermally conductive member also has a second portion positioned exteriorly of the muffler and coupled to the thermally responsive element, the thermally conductive member configured to conduct heat from exhaust gases within the muffler to the thermally responsive element.
