Patent number: 6471301Abstract: A differential mechanism is provided for a dual wheel assembly including a spindle having a drive axle defining a first rotational axis. First and second wheels are supported on the spindle adjacent to one another. The wheels are driven by the drive axle and are rotatable relative to one another about the first rotational axis. A gear assembly having a second rotational axis transverse to the first rotational axis mechanically couples the wheels. A biasing assembly engages the gear assembly thereby preventing relative rotation between the wheels when a torque is applied to one of the wheels below a desired amount from a road input. That is, the biasing assembly and gear assembly cooperate with one another to lock the first and second wheels together so that they are driven together about the first rotational axis by the drive axle. This is desirable when the vehicle is traveling a straight path to provide maximum traction.Type: GrantFiled: November 14, 2000Date of Patent: October 29, 2002Assignee: Meritor Heavey Vehicle Technology, LLCInventor: Michael E.

Publication number: 20020108817Abstract: A drive axle assembly includes a supplemental brake force assembly that utilizes a variable viscosity fluid. The assembly includes a housing defining a cavity and a drive component mounted for rotation relative to the housing. Rotating plates are mounted for rotation with the drive component and a Theological fluid is enclosed within the housing to surround the rotating plates. A current source generates current within the fluid to vary the viscosity. At higher traveling speeds, no current is applied to the fluid so the viscosity of the fluid is low, which reduces drag against the rotating plate. However, when a braking even occurs, current is applied to the fluid to increase viscosity and generate a supplemental braking force. The assembly is preferably incorporated into a wet disc brake with a plurality of non-rotating plates positioned in an alternating dispersal between the rotating plates.Type: ApplicationFiled: April 3, 2002Publication date: August 15, 2002Inventors: Paul Ray Sieber, Mark M. Schneider, Larry W. Bowman, Robert W. Hildebrand, Michael E. Johnson, James R. Brichta, Raji S. El-Kassouf

Patent number: 6397980Abstract: An improved dry disc brake has its housing positioned radially inwardly of its rotating member. In this way, the interface between the pads and the rotor is sealed from the environment. Further, there are two braking surfaces on the rotating member at opposed ends of the housing. Since the braking heat is spread across two surfaces, the system is better able to take heat away from the braking operation. The use of external facing fins adds even more capacity to take heat away.Type: GrantFiled: August 17, 1999Date of Patent: June 4, 2002Assignee: Meritor Heavy Vehicle Systems, LLCInventor: Michael E.

Patent number: 6362229Abstract: The present invention relates generally to the fields of bacteriology and mycology. More particularly, the present invention provides novel inhibitors of multidrug transport proteins that may be used in combination with existing antibacterial agent and/or antifungal agents to increase the toxic effects of the antimicrobial agents. More specifically, the present invention provides methods and compositions for enhancing the antibacterial action of fluoroquinolones by administering fluoroquinolones in combination with an inhibitor of multidrug transporters and of enhancing the antifungal action of azole antifungal agents by administering an azole antifungal agent in combination with an inhibitor of multidrug transporters. Compositions comprising indole, urea, quinoline or aromatic amide based inhibitors also are disclosed.Type: GrantFiled: August 17, 2000Date of Patent: March 26, 2002Assignee: Influx, Inc.Inventors: Penelope N. Markham, Debbie C. Mulhearn, Alexander A. Neyfakh, David Crich, Mohamad-Rami Jaber, Michael E. Johnson

Patent number: 6264009Abstract: A multi-stage wet disc brake assembly has a first actuator is supported within a housing and moveable toward point of friction discs. A second actuator coacts with the first actuator and is moveable relative to the first actuator toward the friction discs. One of the actuators reduces the running clearance between the friction discs and the other of the actuators forces the friction discs together to slow rotation of a rotatable member relative to the housing when the rotatable member is being driven.Type: GrantFiled: June 3, 1999Date of Patent: July 24, 2001Assignee: Meritor Heavy Vehicle Systems, LLCInventor: Michael E.

Patent number: 6206798Abstract: A differential apparatus for controlling the wheel speed of a vehicle includes a primary driving input, and first and second output shafts. The differential apparatus also includes a first planetary gear system in driving engagement with the first output shaft for rotating the first output shaft, and a second planetary gear system in driving engagement with the second output shaft for rotating the second output shaft. At least one auxiliary input mechanism selectively drives the first and second planetary gear systems for rotation in opposite directions to effect different rotational speeds to the first and second output shafts, thereby controlling the wheel speed of the vehicle.Type: GrantFiled: September 3, 1999Date of Patent: March 27, 2001Assignee: Meritor Heavy Vehicle Systems, LLCInventor: Michael E.

Patent number: 6173523Abstract: A sonic plastic bait has an elongated cylindrical body. Ventral fins are longitudinally aligned in an oblong design along the lower edges of the bait body as a continuation of a belly portion. The belly portion and the fins form the continuous flat underside surface of the sonic bait. The upper part of the body has a rounded back raised above where the ventral fins protrude along the sides. At a front end, the bait body is shaped head-like. Towards the rear end, the bait body slants downward to a size approximately aligned with the ventral fin thickness and forms into a split tail section resembling flukes. The ventral fins are sectioned into individual appendages that vibrate or touch each other and produce a low sound attractive to fish when the sonic plastic bait is pulled through water.Type: GrantFiled: July 15, 1999Date of Patent: January 16, 2001Inventor: Michael E.

Patent number: 4968049Abstract: A mattress moving arrangement includes a plurality of legs configured in "A" shaped orientation formed with an orthogonal extending handle relative to the intersection defined by the aforenoted legs. The lowermost portion of the legs include "L" shaped members for receiving a mattress therewithin. Modifications of the invention include castor wheels revolvably mounted and extending downwardly from the "L" shaped legs, and additionally may include strap members joined together at a ring portion originating from each of the "L" shaped members for surrounding relationship relative to a mattress cradled within the invention, and wherein the ring is positionable about the upper handle for securement of the mattress within the device. Further, a second handle may be pivotally mounted relative to a cross brace member directed between the legs.Type: GrantFiled: September 27, 1989Date of Patent: November 6, 1990Inventor: Michael E.

Patent number: 4388644Abstract: A system for monitoring the operation of a multichannel receiver includes a channel monitor coupled to the sync separator of the receiver for collecting and transmitting channel information to a central collector station. The collector station selectively responds to one of a plurality of channel monitors to record, in sequential order, channel information. Each of the channel monitors is similar and includes a synchronizing pulse generator triggered by the vertical synchronizing pulse from a receiver to generate a match recognize pulse when a frequency coupled to the receiver from the monitor and the channel frequency have a preestablished relationship. To generate the match recognize pulse a counter provides signals to a tuning matrix that controls a frequency synthesizer or plurality of oscillators for generating the frequency coupled to the receiver for the match evaluation. Also, the counter activates a data encoder that provides channel information to the collector station.Type: GrantFiled: February 12, 1980Date of Patent: June 14, 1983Assignee: E-Systems, Inc.Inventors: Neal H.
