| 20140301802 | Zero-Backlash Bushing - A zero-backlash bushing employs a dual-component composite design, comprising a tapered resilient slotted bushing core compressibly engaged by a cylindrical annular sleeve. As opposed to the axial pressure of a locking nut, the annular sleeve exerts a circumferential pressure on the bushing core, thereby inducing a tight radial engagement between the threads of the bushing core and the adjustment screw, as opposed to the lateral thread engagement induced by a locking nut. This tight radial engagement leaves radial gaps between the threads of the bushing core and the screw, which radial gaps can be filled with grease. Slots in the bushing core enable migration of grease within the bushing and facilitate constriction of the bushing core. | 10-09-2014 |

| 20150139748 | EXPANDING FASTENER - Fasteners are generally described. In some examples, a fastener can be secured to a first member or it can secure a second (or further) member to the first member. The example fastener can include a body for location with respect to the first member. The example fastener can also include at least one latch which can be located with respect to the body. The latch can move laterally with respect to the body from a non-latching position to a latching position. The example fastener can also include an actuator. The actuator can protrude from the body as the actuator moves from an inactive position to an active position. When the actuator is in the inactive position and the at least one latch is in the non-latching position, the body can be located with respect to the first member. When the actuator is moved to the active position, a part of the actuator which protrudes from the body can cause the at least one latch to move laterally to the latching position such that it is able to latch behind the first member (or behind second or further members) to facilitate securement of the fastener thereto. | 05-21-2015 |
