International Classification:

B07B 402

US Classification:

209137

Abstract:

An air classifier for separating a heterogeneous mixture of particles into heavier and lighter fractions includes an air passageway through which a horizontal primary air stream is flowing, a pair of air deck sections extending along the bottom of the passageway through which deck air is flowing upwardly within and downstream of the passageway, air nozzles located between the air deck sections through which a primary vertical air stream is flowing, the latter also preferably flowing with a horizontal component moving downstream of the passageway, a heavy particle deflector and remover downstream of the second air deck section, and a light particle trapping and removal arrangement downstream of the heavy particle deflector. The particle mixture is introduced into the passageway over the first air deck section just upstream of the primary vertical air nozzle, whereupon the particles are immediately stratified in horizontal layers of heavy and light fractions by the upward air currents and transported to the end of the passageway by the horizontal air currents, where the fractions are separated from the air flows and removed from the passageway.

US Classification:

204 9

Abstract:

The present invention is an improved capstan which is used in a magnetic tape transport system, to accelerate a length of magnetic tape. The capstan includes a cylindrical post, adapted to be connected to a drive shaft of a capstan motor in a magnetic tape transport system, a pair of discs, each of which has a set of outer holes disposed adjacent to and distributed about its periphery and a set of inner holes disposed adjacent to and distributed about its central axis, coupled together by the cylindrical post disposed about their central axes. The capstan also includes a first set of cylindrical posts, coupling the inner holes of one disc to the inner holes of the other disc, and a second set of cylindrical posts, coupling some of the outer holes of one disc to some of the outer holes of the other disc. The capstan further includes a cylindrical tape band, which has a set of grooves running concentrically with the discs and the other edges of which are joined to the peripheries of the discs. The capstan if formed by a two step process of plating a platen in the shape of the capstan with a metal, such as nickel, and then dissolving or etching away the platen in a selected solution.

International Classification:

G11B 1558

US Classification:

242182

Abstract:

The invention is a tape path of a magnetic tape which is incorporated in a tape transport system. The tape path includes a file reel and a machine reel, each reel driven by a drive motor, a capstan, a magnetic head and a control system for controlling the two drive motors and the capstan. The tape path also includes a pair of vacuum chambers disposed in a V with the vertex of the V formed at their closed ends, a pair of auxiliary vacuum chambers disposed adjacent to each vacuum chamber, and a set of rollers and air bearings to guide the magnetic tape along the tape path.
