A three dimensional shade to provide a three dimensional layer structure and profile includes a movable frame and a shade. The apparatus includes an ultrasonic emitter such as a cylindrical emitter and an inflatable annular lens balloon surrounding the ultrasonic emitter. The inventive transport and securing system includes optional releasable chest and stomach straps to supplement the mechanical restraint system. The strobe controller may be incorporated in a housing for operatively enclosing a digital camera for use underwater or in harsh environments. In a second embodiment of the invention the floating-trailing shield extends around the sides of the main pole piece to reduce the off-track magnetic field. The method is particularly useful for making robust slurries for subsequent spray drying of free flowing granules to be used in the fabrication of cemented carbide or cermet bodies.
