A dual-head gamma camera imaging system comprises a master ring gear and a slave ring rotatable about a longitudinal axis. The master ring gear is rotatably supported by a gantry. The slave ring is rotatably supported by the master ring gear and concentric with the master ring gear, such that the master ring gear and the slave ring can be rotated independently about s longitudinal axis. A first detector is supported by a first cantilever support member mounted to the master ring gear. A second detector head is supported by a second cantilever support member mounted to the slave ring. The angular displacement between the detector heads can be varied by providing relative rotation between the master ring gear and the slave ring. The rotation can be accomplished by using the weight of one of the detector heads to hold that detector head stationary while rotating the other detector head using a motor. The imaging system also includes a mechanism for rotating a detector head about an axis perpendicular to its imaging surface to increase the field of view along the longitudinal axis. The detector is mounted to an inner support ring which is rotatably coupled to and concentric with an outer support ring. The outer support ring is mounted to at least one ring gear.

A method and system are provided for forming floppy disk envelopes. Envelope blanks are manipulated while attached to a continuous web of envelope material to facilitate handling and alignment of the blanks. Initially, fold lines are impressed into the envelope blanks to define the precise dimensions of the envelope. Envelope flaps are then partially folded to define a receptacle into which the disk media is then inserted. The remaining flaps are then folded and sealed, and lastly the folded envelope is detached from the continuous web. A particular apparatus for impressing the envelope blanks includes a male die, female die cavity, and mechanism for reciprocating the dies. The preferred score profile includes a pair of radii joined by a hinge section.

A method and system are provided for folding floppy disk envelopes. Envelope blanks are manipulated while attached to a continuous web of envelope material to facilitate handling and alignment of the blanks. Initially, fold lines are prescored into the envelope blanks to define the precise dimensions of the envelope. Envelope flaps are then partially folded to define a receptacle into which the disk media is then inserted. The remaining flaps are then folded and sealed, and lastly the folded envelope is detached from the continuous web.

A dispensing device for sequentially dispensing sheet material such as paper toweling from a primary roll and a reserve roll, the primary roll initially being rotatably mounted at a first location and adapted to be displaced therefrom to a second location. Sheet material feed means is provided for dispensing the sheet material from the device. Sensing means is provided for sensing displacement of the primary roll from the first location and transfer means is employed in operative association with the sensing means and responsive to the sensing of the displacement of the primary roll from the first location to place sheet material from the reserve roll into operative engagement with the sheet material feed means. The transfer means includes metering means for metering sheet material removed from the primary roll by the feed means after displacement thereof has been sensed by the sensing means, said transfer means being responsive to the metering of a length of sheet material having been removed from the primary roll before placing the sheet material from the reserve roll into operative communication with the sheet material feed means.
