IPC: E21B33/02
Filed: 2015-06-19
Abstract: An annular drilling device is provided that employs an active or passive, stationary sealing element. More specifically, rotating annular drilling devices commonly used depend on externally pressurized sealing elements that are energized by wellhead pressure or hydraulic pressure to grip a rotating drill pipe and rotate with the drill string. Thus, a plurality of rotary seals and bearings must be used. Here, however, the passive or active sealing element is stationary, thereby eliminating the need for bearings, etc. The passive or active stationary sealing element is made of a low-friction material that contacts the drill pipe, creates a seal, and does not adversely affect drilling operations.

Abstract: Discrete items are conveyed, preferably by a vacuum conveyor, in a machine direction toward a pair of rotating blades. A first intended target of folding, for instance a right portion of front and back panels of a diaper, travels up a ramp, raising the level of the intended target. A rotating blade passes under the intended target of folding, and folds the right portion of front and back panels of a diaper over. If desired, a second intended target of folding, for instance a left portion of front and back panels of a diaper, travels up a second ramp, raising the level of the intended target. A rotating blade passes under the second intended target of folding, and folds the left portion of front and back panels of a diaper over. The folded diaper then exits the folding system and travels downstream for further processing as desired.

Title: Indexable washer system for wheel alignment correction
Inventor: MERRILL ZACHARY ALEXANDER
IPC: B62D17/00
Filed: 2015-03-10
Abstract: A system for wheel alignment provides an indexable pair of washers in conjunction with a sleeve having non-concentric inner and outer surfaces that allow for adjustments to camber, toe, and thrust. The system can be retrofitted to existing axle systems using a sleeve that fits over the spindle of the axle. Rotation of the sleeve relative to the spindle provides for adjustment to wheel alignment. The indexable washers can be used to determine the precise amount of adjustment and fix the position of the sleeve once adjusted. The system can be implemented regardless of the circumferential position (i.e. azimuthal orientation) of a keyway or groove on the axle spindle that is typically used to lock the position of the axle nut.
