Abstract

723,814. Housings for radio-active sources of radiation. GILKS, E. -N., and GAMMA RAYS, Ltd. June 21, 1952, No. 16701/62. Addition to 711,532. Class 98 (1). A container for radioactive material of the kind comprising a block of material impervious to radiation with a removable plug includes a plug supporting and guiding structure establishing a predetermined path for the plug between its closed and open positions, in the latter of which the plug is displaced to one side of the path of radiation, and actuating mechanism with a single operating member stationarily situated out of the path of radiation and mounted for turning movement about an axis to move the plug along its path. From another aspect, the mechanism establishes a conversion as between the mode of movement of the operating member and that of the plug, the operating member remaining in or substantially in a fixed location in relation to the body of the container and out of the path of the radiation whilst operated, and serving to move the plug along a path having components extending both parallel and perpendicular to the general direction of the path of radiation. As shown in Fig. 1, and in plan in Fig. 2, the carriage has a U-shaped base resting on wheels 13 and a foot 17, and supports the container 19 on similarly curved arms 18. A socket 14 may receive a handle. Stub shafts fixed on opposite sides of the container are journalled on arms 18. The container may be tilted by a handle 33 on a shaft 31 having a worm wheel engaging a pinion fast on one of the stub shafts. The container 19 has a hollow body, Fig. 3, containing a block 38 of lead or similar dense material. A capsule 43 containing the radioactive material is fixed to a stem 44 slidable in a guide tube 45 in a bore in the block 38. The bore leads into an opening of stepped frusto-conical shape, which is normally closed by a plug 47. A screw-threaded portion 40 of the body can be removed for insertion or adjustment of the stem 44. Plug 47 is supported on an arm 50, Figs. 1 and 2, connected to a cross-head 52 fixed to bars 55, 56 sliding in a housing 61. Bar 55 has rack teeth, Fig. 4, engaging a pinion 69, and bar 56 carries at its free end a roller 62 movable in a cam track 63 formed in a plate 64 fast with the container 19. A hand wheel 74 drives, through worm gearing, the pinion 69, so that plug 47 is first moved out of its seating, and then, through action of roller 62 and cam track 63, is moved into the position indicated at 67 in Fig. 1, permitting the emission of radiation from the container. A key-operated cylinder-type lock 77, Fig. 2, is provided in housing 61 to lock hand wheel 74. A similar lack 83, Fig. 3, locks the removable portion 40 in position. The stem 44 may be locked in position by an eccentric cam 88 entering a slot in sleeve 45 and operated by a lever 89, which is only accessible when the portion 40 has been removed.
