Abstract: A device for obtaining surveillance information from an aerial vehicle. The device includes a camera configured to obtain image data based on a position of the vehicle, a transceiver configured to receive operator controls and output the obtained image data, a designator unit configured to emit a light source onto a surface of an object of interest to illuminate that surface when a designation command is received from an operator, a gimbal mechanism having a plurality of motors configured to orient the designator unit, a gimbal controller configured to control the motors of the gimbal mechanism, and a controller configured to control the designator unit to continuously emit the light source onto the surface of the object irrespective of the position of the vehicle. The controller compensates for an orientation of the designator unit based on the aerial vehicle's movement such that the designator unit continuously illuminates the object.

Abstract: The production of plied yarn in pot spinning in which a pot is filled with yarn emerging in one direction from a reciprocating traversing tube. When the pot is filled to the desired extent a lead yarn is injected into the pot by pneumatic means in a direction opposite to the said one direction so that yarn from the traversing tube is wound around the lead yarn. The lead yarn is then withdrawn from the pot in said one direction and the yarn in the pot is wound around further yarn from the traversing tube.
