Abstract: A web-guiding system for guiding a web of media along a transport path comprising a drive roller rotated by a motor and a plurality of nip rollers. The drive roller includes a first section, a second section and a third section along the length of the roller, the second section being located between the first section and the third section. A diameter of a surface envelope around the exterior surface of the drive roller is substantially constant within the second section, and is larger in the first section and the third section than in the second section. The nip rollers are aligned with the second section of the drive roller, with the web of media passing between the drive roller and the nip rollers.

Abstract: A cassette (10) for photosensitive web material includes a hollow housing (12) having a peripheral wall (16); an exit slit (42) extending through the peripheral wall; a device (20), located within the housing, for rotatably supporting a roll (22, 24) of web material; a mechanism (32, 38), located within the housing, for engaging a lead end (26) of a web material to drive the web material through the exit slit; a knife blade (134, 136) having a cutting edge (138) extended at an acute angle to the exit slit; a recess (132) for slidably mounting the blade for movement between a first position in which the exit slit is open, and a second position in which both the web material has been cut by the cutting edge and the exit slit has been closed by the blade to prevent entry of light into the housing through the exit slit; and a knife bed (142, 144) fixedly mounted on the housing, the blade being in sliding engagement with the knife bed, whereby the blade and the knife bed cooperate to scissor the web material as th

Abstract: A valve assemblage (10, 50) for controlling the flow between fast and second containerized systems (C.sub.1, C.sub.2) having first and second openings (A,B), respectively. The assemblage comprises a first valve assembly (12, 52) positioned at the first opening of the fast containerized system and a second valve assembly (14, 54) positioned at the second opening of the second containerized system. A piston (20, 84) in the first valve assembly, when in a first position opens an entrance port (18, 100) for receiving fluid from or passing fluid into the first containerized system; and correspondingly, a retractable sleeve (36, 136) in the second valve assembly (14, 54) opens an entrance port (30, 122) in a proboscis member (26, 110) having a channel (28, 118) and outlet (32, 142, 144) for passing fluid to or receiving fluid from the second containerized system.
