Abstract: A camera support includes a pole formed of a first tubular member and two tubular end members telescopingly mounted in the first member and releasably extendable outward therefrom for supporting the pole between two opposed surfaces, such as a ceiling and a floor. An arm supports a camera at one end and is slidingly and rotatingly mounted to the first tubular member at another end for variable positioning of the camera with respect to the pole. The arm may alternately be configured with telescopingly engaged legs for adjusting the length of the arm with respect to the pole. A base with outwardly extending, pivotal legs may alternately be attached to the pole for supporting the pole in an upright position. A pair of carriers are attachable to the pole to mount the alternate base to the pole for transport with the camera support.

Abstract: A protective shield device for mounting on an X-ray machine in the path of an X-ray beam characterized as including a first shield plate having a control aperture bounded by material opaque to X-rays, which is adapted to be disposed in alignment with the X-ray beam for limiting the size and configuration of such beam to that of the control aperture; and a second shield plate having first and second apertures, which are bounded by material opaque to X-rays and adapted to be selectively/alternately positioned in alignment with the control aperture upon relative movements of the first and second shield plates in order to selectively provide for three X-ray beam configurations varying in size and/or configuration one from another.
