摘要： A self-contained room capable of shielding the interior environment from magnetic and radio frequency interferences, as well as other wave and vibrational disturbances, comprised of an outer enclosure and an inner enclosure, raised above an existing floor by a fiberglass dowel system. The walls of both enclosures are made of mumetel sheets, pressure sealed to protect against ambient and man-made interferences, with an underlying aluminum structural frame. All seams and penetrations are shielded against wave interferences of natural or man-made origin.

摘要： This invention relates to the use of suspended materials as a backdrop for photography or stage productions. The suspended materials may be stored on a spool device. Such spool devices may include tubes or spindles constructed of metal, of cardboard, of plastic or other lightweight and inexpensive materials. The spool device may also include means for attaching the tube or spindle to a lifting device. Such attachment means may include a pair of interconnectable coupling devices, one fixed to the spool and the second attached to the lifting device.
