An apparatus for a thrust reverser actuation system (“TRAS”), the apparatus comprising: an input shaft; a first component located concentrically around the input shaft; a second component located concentrically around the first component; a first ballscrew mechanism between the input shaft and the first component, and configured such that rotational movement of the input shaft causes a translational movement of the first component via the first ballscrew mechanism; and a second ballscrew mechanism between the first component and the second component, and configured such that rotational movement of the first component causes a translational movement of the second component via the second ballscrew mechanism.

A hand operated tool for binding a load. The tool including a hollow tube with interior left hand and right hand threads at opposing ends. Opposing rods with exterior threads on one end and a releasable connection device on the other end that is screwed into each end of the tube. A gear rigidly mounted and encircling the tube allowing a pivotly attached ratcheting U-pawl to engage the gear teeth, the U-pawl attached to and carried by a handle assembly mounted on each side of the gear, the handle protruding perpendicular from the tube. The handle turning the tube in a first rotational direction drawing the rods closer together tightening the bind, the handle turning the tube in a second rotational direction moving the rods farther apart loosening the bind, the rods remaining stationary in rotation during rotation of the tube. A blocking device may be installed to prevent the U-pawl from pivoting into a position to turn the tube in the second rotational direction, that would loosen the bind on the load, the blocking device allowing normal ratcheting and turning of the tube in the first rotational direction tightening the bind on the load. A recessed-pawl partially pivoting independently of the U-pawl and engaging with the gear to prevent the tube from turning in the second-rotational-direction that would loosen the bind on the load when the U-pawl is in a neutral position whereby the U-pawl is not engaged with the gear. In addition, a tension-detecting-device suitable to detect or measure the tension on the ratchet load binder rods and also monitor and communicate the tension to the operator is also provided.

An actuator is suitable for providing linear motion between two points, and may be used, for example, in motorized positioning of an automobile steering column. The actuator includes a threaded spindle connected to a drive motor via a gear set, a first connection interface mounted on the spindle and engaged with the spindle thread, and a second connection interface mounted on the spindle and engaged with the spindle thread. The second connection interface is moveable along the spindle axis relative to the first connection interface when the spindle is driven by the drive motor. The actuator is arranged such that the first and second connection interfaces are disposed on the same side of the gear set.

A novel deformation motion mechanism with precise motion precise motion and structural robustness is achieved. A deformation motion mechanism includes: an elastic ring member shaped symmetrically with respect to a center line, wherein one end of the elastic ring member is fixed and the other end is movable along the center line; a drive unit which is placed within the elastic ring member and is arranged to rotate a feed screw engaged with both ends of the elastic ring member along an operating line orthogonal to the center line, to press or stretch the elastic ring member along the center line; and a plurality of flexible arms which connects the drive unit to the elastic member in at least a direction of the center line.

A lifting column includes a component having an internal thread, as well as a hollow shaft having an external thread, which is in engagement with the internal thread of the component. A threaded spindle is disposed inside the hollow shaft and has an external thread, which is in engagement with an internal thread of the hollow shaft. Furthermore, the lifting column includes a drive device configured to rotate the hollow shaft relative to the threaded spindle and the component. When the hollow shaft rotates, the component and the hollow shaft move in the same axial direction so that the height of the lifting column is changeable.

The present invention provides an adjustment arrangement (10), comprising a rotating input element (26) at which a first torque from a motor arrangement (18, 22) can be inputted into the adjustment arrangement, a rotating output element (16) at which a second torque can be outputted by the adjustment arrangement, and a transmission portion for converting the first torque into the second torque, the transmission portion comprising a transmission means (32) having a first threaded portion (30) and a second threaded portion (34), the first threaded portion converting a rotation of the input element (26) into an axial movement of the transmission means, and the second threaded portion converting an axial movement of the transmission means into a rotation of the output element (16).
