Patent GB-631289-A (GB)
Abstract: 631,289. Rontgen-ray apparatus. POITTE. VIN, M. Sept. 1, 1947, No. 24113. Convention date, Aug. 29, 1946. [Class 98 (i)] The apparatus has a panel for positioning the subject guided for movement relative to the support for the fluorescent screen or sensitive surface by means connected to the support. As shown, the screen or equivalent 4 is carried by a bracket 5 slidably attached to a column 6, which may itself be adjustably supported. A rod 11, fixed to the bracket 5 at right-angles to the plane of the screen, carries a sliding sleeve 9 to which the frame 8 of the panel 7 is attached by an arm 10. A projection 13 on the arm 10 is shaped to engage a rod 12 fixed to bracket 5 parallel to the rod 11- to prevent relative rotation between the screen 4 and panel 7. A rod 15 parallel to rods 11 and 12 is fixed to the arm 12 near the sleeve 9 and terminates beyond the screen. When the subject 1 presses against the panel 7 for irradiation by a tube 3, the couple applied to the sleeve 9 produces sufficient friction to prevent sleeve 9 from sliding on rod 11. When the operator 2 pushes rod 15, however, the couple, and the friction produced thereby, are less, and the sleeve slides on rod 11. In a modification, screen 4 and panel 7 are pivotally supported on bracket 5 and arm 10 respectively. In a further modification, the guiding rod passes through a sleeve in bracket 5 and rod 12 is omitted.
