Abstract: A subambient pressure feature for assisting in guidance of storage tape within a tape transport system such as a data storage tape cartridge and/or a tape drive. The storage tape is extended between two tape reels along a tape path defined, in part, by a tape guide. The tape guide includes a curved tape-receiving surface defined by an entrance side and an exit side. The subambient pressure feature is located along the tape path and is adapted to induce frictional engagement between the tape and at least a portion of the tape-receiving surface at speeds of not less than 1 meter/second to suppress lateral tape motion.

Abstract: The present disc opener assembly for a seed planter is for a single disc opener arrangement and is embodied in several embodiments. FIGS. 1 and 1a illustrate two embodiments of the present disc opener assembly the specifics of each will be described below. Referring now to FIGS. 1, 1a and 2, there is illustrated a disc opener assembly (10) mounted on a tool bar (7) connected to a work vehicle (5) for opening a seed trench (8) in the ground upon which the vehicle (5) moves. A main arm (12) is attached to the tool bar (7) with a disc (14) mounted for rotation on the main arm (12). A depth adjustment mechanism (40) is used to adjust the depth of the disc (14) in the seed trench (8) with a seed placement device (70) positioned in the seed trench (8) for depositing a seed (71) in the seed trench (8). The seed trench (8) having been opened by the disc (14) as the work vehicle (5) moves across the ground.
