Abstract: Byproduct condensate generated during additive manufacturing is controlled by providing at least one electrode inside a chamber. The condensate may be electrically charged as it is generated or an electrical charge may be imparted to the condensate. The electrode may have either a positive or negative bias to either attract or repel the condensate. The electrode may be located on a wall of the chamber or associated with a transparent window through which a laser beam passes into the chamber.

Abstract: Surface and sub-surface defects are removed during additive manufacturing. After a layer of an object is formed in a powder bed, a portion of the layer is removed while the object is in the powder bed to remove surface and or sub-surface defects. The removal step may be performed on a layer-by-layer basis. A directed energy beam or tool may be used to remove a shallow object-powder interface portion of the layer, or a deeper skin portion of the layer. In this way, the completed object may be removed from the powder bed substantially free of surface roughness and sub-surface defects.

Abstract: A rotor assembly of an electric motor generally comprises a center shaft configured to rotate about a longitudinal axis and a plurality of spacers extending radially outward from the center shaft, the spacers fixedly attached to the center shaft. A plurality of axially stacked annular laminations are coaxially aligned with the center shaft and radially supported on an inner circumferential surface by the plurality of spacers. Each of the plurality of spacers has, at each axial end of the stacked annular laminations, first and second axial restraining elements extending in an outward radial direction beyond the inner circumferential surface of the plurality of stacked annular laminations. The plurality of stacked annular laminations are compressed between the first axial restraining element and the second axial restraining element, such that an axial compression force is applied to the plurality of stacked laminations.

Abstract: A directional cold spray nozzle defines a flow passageway that includes a bend for redirecting flow from a first flow direction to a second flow direction different from the first flow direction, wherein the flow passageway is divergent through at least a portion of the bend. The flow passageway may be convergent prior to becoming divergent in the path of flow. The directional cold spray nozzle simultaneously accelerates the powder and carrier gas and changes the spray direction of the spray plume to reach interior bore surfaces and other surfaces that are difficult or impossible to reach with a straight nozzle.

Abstract: A power spring passively applies tension to a cable connected to an aircraft refueling boom. The power spring has a first end engaging a fixed arbor and second end engaging a rotatable spooling drum around which a portion of the cable is wound. The power spring biases the drum to rotate in a winding direction to apply tension to the cable, and the power spring stores energy when the drum rotates in an unwinding direction. The power spring may be located inside the drum or outside the drum. The drum may be actively driven by a motor that may be uncoupled from the drum to permit freewheeling rotation of the drum, wherein the power spring continues to apply tension to the cable. The invention eliminates reliance on one or more powered motors for removing unwanted slack in the cable.

Abstract: A torque limiter limits transmission of torque between an input shaft an output shaft. The torque limiter may be incorporated in a geared rotary actuator for actuating an aircraft control surface. The torque limiter is responsive to output torque associated with the output shaft instead of input torque associated with the input shaft. The torque limiter includes a structural ground and a gear assembly for transmitting rotational motion of the input shaft to the output shaft. The gear assembly includes a reference gear coupled to the structural ground such that movement of the reference gear relative to the structural ground is dependent upon an output torque at the output shaft. The reference gear is stationary relative to the structural ground when the output torque is below an output torque limit, and the reference gear moves relative the structural ground when the output torque exceeds the output torque limit.

Abstract: A stop module halts rotation of a shaft of a rotational drive system when an axial stroke limit is reached without the use of frictional brake plates. The module has a fixed nut and a pawl carrier coaxially mounted on the shaft for axial travel along the shaft and rotation with the shaft. The pawl carrier includes a screw portion mated with the nut such that rotation of the pawl carrier with the shaft causes the pawl carrier to travel axially along the shaft. A pawl member is pivotally coupled to the pawl carrier, and a stop element is fixed at an axial limit location. The pawl carrier is axially displaceable from a non-limit position wherein the pawl member is clear of the stop element during rotation to a limit position wherein the pawl member is interfered with by the stop element during rotation to stop rotation of the shaft.
