Abstract: INCREASING DOSAGES OF X-RAY RADIATION PROGRESSIVELY LOWER THE COLOR-PLAY RANGE OF CHOLESTERIC-PHASE LIQUIDCRYSTAL MATERIALS. THE EFFECT IS ENCHANCED WHEN AND EFFECTIVE AMOUNT OF AN IODINE-CONTAINING COMPOUND IS USED IN THE LIQUID-CRYSTAL MATERIAL. NOVEL IODINE-CONTAINING COMPOUNDS ARE DESCRIBED, AND ARTICLES ARE DISCLOSED THAT GIVE DIRECT-READING INDICATION OF THE DOSAGE OF X-RAY RADIATION THAT THEY HAVE RECEIVED, WITHOUT NEED FOR A SEPARATE DEVELOPMENT OPERATION.

Abstract: A fluidizing bed tank is disclosed which has vertical walls enclosing a space, a horizontal porous gas diffuser plate between the walls, means for providing gas beneath the diffuser plate, and at least one horizontal protective screen between the walls and above the diffuser plate. The uppermost screen is at least about two-thirds of the distance down from the top of the tank to the diffuser plate. A second screen is preferably used when the heavy articles are to be coated.
