摘要： The present invention provides a process of encapsulating depleted uranium by forming a homogenous mixture of depleted uranium and molten virgin or recycled thermoplastic polymer into desired shapes. Separate streams of depleted uranium and virgin or recycled thermoplastic polymer are simultaneously subjected to heating and mixing conditions. The heating and mixing conditions are provided by a thermokinetic mixer, continuous mixer or an extruder and preferably by a thermokinetic mixer or continuous mixer followed by an extruder. The resulting DUPoly shapes can be molded into radiation shielding material or can be used as counter weights for use in airplanes, helicopters, ships, missiles, armor or projectiles.

摘要： The conventional chroma key television process is used to effect composite images by employing a master camera whose subject may be live action against a single hued background and a slave camera directed at a static background, such as a miniature set or a back-projection screen. The inventive process includes the steps of linking the master and slave cameras so that a sensing of the current flow in the actuating motors for panning, dollying, trucking or otherwise changing the master camera causes a scale-related like motion of the slave camera, each camera moving in proper ratio with respect to its subject. The slave camera image is fed to the conventional mixer and fills that portion of the composite image occupied by the single hued background of the master camera subject image. A time delay may slow transmission of the master camera to the mixer if it is found that the action or motion of the slave camera lags behind the like action or motion of the master camera.

摘要： A video camera tilt and pan head includes a bifurcated support which is free to pivot about a vertical axis for the "pan" action of the video camera. A camera cradle receives the video camera and the cradle is provided with slots and a tie-down bolt such that the camera is adjustable horizontally with respect to the cradle. The cradle is supported on transverse mounting pivots secured in the support. The pivots clamp in vertical cradle slots, enabling the cradle to be adjustable vertically with respect to the pivots. The pivots may be tubular to act as sight tubes to locate the cradle and camera with respect to the desired pivot axes. A tray extends from the cradle to receive weights to counterbalance the extension of the video camera beyond the transverse pivots. The camera exterior is indexed to indicate the point at which the axes of each of the red, green and blue receptors intersect the lens axis of the camera. This point establishes the desired path for tilt and pan axes. Motorized gear drives accomplish tilt and pan motions of one camera in response to the selective movement of like pan and tilt gears on a companion camera such that the companion camera and a camera fixed in the mount of the invention move in synchronism.
