Abstract
Abstract An automatic air pillow assembly for diagnostic X-ray machines adapted for mounting on a tiltable examination table having a compressor motor flowing air automatically through a three-way valve into an inflatable pillow. The valve is actuated by a mercury switch which senses the table position and allows flow into the pillow when the table is horizontal and cut when it is vertical. Various clamping means are provided to attach the pillow to different types of tables.
