Abstract: Described herein is a nut shelling device and method of manufacturing a nut shelling device that includes a cylindrical housing, a drum positioned in the cylindrical housing, an actuating cap rotatably coupled to the cylindrical housing and coupled to the drum, a containment receptacle coupled to the cylindrical housing, a first sieve coupled to the cylindrical housing, and a second sieve positioned in the containment receptacle.

Abstract: A flat head and a tape transport arrangement impart a wrap angle to the tape at the upstream corner of the head. The wrap angle, corner sharpness and tape stiffness are sufficient to cause a moving tape to form a hollow bump at the upstream corner, thereby creating a hollow into which entrained air can expand, causing a subambient pressure within and downstream of the bump. This pressure keeps the tape in contact with the head. It is created without the need for a groove or complex pressure relief slot(s). No contact pressure arises at the signal exchange site due to media wrap. The highest contact pressures are developed at a wrapped upstream corner. For a tape drive, traveling in both forward and reverse, the wrap can be at both the upstream and downstream (which is the "reverse upstream") corners. Heads that are not flat can also be used, if the wrap angle relative to a main surface is sufficient and not too large.
