| 20110191034 | Portable System for Immotive Multiphasic Motive Force Electrical Machine Testing - A portable test device ( | 08-04-2011 |
| 20100258990 | CARTRIDGE AND ROD END ISOLATOR - An elastomer-containing rod end isolator. The isolator includes a handle for connection to a load and inner and outer members. The outer member is a pocket and the inner member is spherical or nearly so. The pocket and the inner member are concentric and the inner member has two continuous exterior legs extending in a circular path. An elastomer fills most of the space between members. | 10-14-2010 |
| 20100194224 | Magnetic bearing assembly for rotors - A rotor assembly includes a rotor having a central axis extending between the two opposing ends and a radial surface, and is rotatable about the central axis. At least one electromagnet is disposed proximal to and configured to exert magnetic force on a portion of the rotor. Further, a channeling member is disposed generally adjacent to the electromagnet and has a radial surface disposed adjacent to the rotor radial surface. As such, magnetic flux generated by the electromagnet extends generally radially between the electromagnet and the rotor portion and generally axially between the rotor portion and the channeling member so that the magnetic force biases the rotor both radially and axially to maintain the rotor at a desired position. Preferably, the assembly includes a plurality of magnets proximal to each end, two channeling members, and a tubular body extending between the channeling members and enclosing the rotor. | 08-05-2010 |
| 20100133759 | LARGE DIAMETER SEALS - A large diameter seal having a band of elastic material on its outer diameter to insure a complete and effective sealing in the counterbore and a method for manufacturing this large diameter seal having elastomeric material on its outer diameter. | 06-03-2010 |
| 20100072709 | SEAL WITH PYRAMID SHAPED FORMATION - A seal assembly having a seal bumper wall with a series of pyramid shaped formations lying on the bumper wall. The formations cause their apex portion to wear down rapidly in use, while the remainder of the pyramids remain and act as slingers and/or produce a convection effect to reduce temperature along the sealed area. In another embodiment, there are two each pyramid shaped formations located on each of several thrust bumpers, which are held in position by a retainer. | 03-25-2010 |
| 20100060289 | System for Electrical Apparatus Testing - An easily implemented method of diagnosing both supply path, upstream, and load path, downstream, anomalies such as impedance events in machine or motor circuitry is accomplished by analyzing the across-the-line startup current and voltage time waveforms. No line of sight limitations exist and high accuracy exists. The techniques can be automated estimating poor contact resistance based on the voltage and current variation under a load change condition perhaps such as startup and/or shutdown of the load. Both, upstream and downstream problems from the point of voltage measurement can be monitored analyzing a load change condition. Additionally, downstream problems can be identified by using negative sequence current under steady state operation of the load. | 03-11-2010 |
| 20090173546 | EARTH BIT WITH HUB AND THRUST UNITS - An earth bit includes a cone rotatably mounted to a shaft with a hub unit and thrust roller bearings. The hub unit is moveable between mounted and unmounted positions on the shaft, as a single unit, in a repeatable manner. The hub unit includes a pair of roller bearings positioned between inner and outer races. The outer race includes a recess extending around its outer periphery. A sealing structure is slidingly engaged with the recess to provide a seal between the cone and shaft. | 07-09-2009 |
| 20080216661 | AIR DRYER SYSTEMS - An air drying system using plural air drying units. The system includes moist air and dry air plenums and a pair of substantially identical air drying canisters. Each unit has a single lower bases and a single, flanged mounting bracket. The moist air plenum is connected to an air inlet in the lower base, and the dry air plenum is connected to a dry air outlet in the lower base. | 09-11-2008 |
