摘要： A magnetic tape cassette transport/accessor assembly is actuated by a sprocket driven, belt drive system. First and second belt drives drive the transport/accessor assembly in horizontal and vertical directions and are tensioned by spring dampener assemblies. Each spring dampener assembly dampens rough and jerky movements and effects smooth and gentle acceleration and deceleration of the transport/accessor assembly. Each spring dampener assembly also provides compensation for belt drive wear, belt stretching and differential thermal expansion and contraction of the belt.

摘要： Any one of several rotary objects of various diameters is gripped between a pair of joined jaws, without a need for manual adjustment of such jaws to any of the various diameters. To this end, the jaws are spaced at a taper to each other for all of the various diameters, and are pivoted, biased and rendered moveable relative to each other in diminution of that taper against the bias and conversely in self-restoration of the taper by the bias upon a release of the object from the jaws. Any one of the rotary objects may be wedged between the jaws at the taper, and one of the jaws is propelled with such wedged rotary object against the bias relative to the other jaw of the pair in diminution of the taper until the jaws exert optimum grip on the object. A loosening or other operation may then be performed on the wedged rotary object, and such wedged rotary object may be released from the jaws [for self-restoration of the taper by the bias.

摘要： A magnetic tape cassette helical scan magnetic tape recorder has a magnetic tape threading and transport apparatus including multi-surface, multi-radius air bearing blocks for transporting magnetic tape in a helical path around a tilted rotary head scanner. Vacuum walls located on either side of the rotary head scanner assist in threading the magnetic tape from a magnetic tape cassette around the rotary head scanner. The air bearing blocks are moved into position contiguous to the rotary head scanner after the vacuum threading operation is completed. The vacuum walls have longitudinal slots which are substantially coextensive with the extent of the air bearing blocks. A vacuum sensor is positioned at the end of the slots away from the rotary head scanner so that the sensor is only actuated when the tape is against the whole length of the wall. This prevents damage to the tape when the air bearing blocks are moved behind the threaded tape.

摘要： A web, contained in a cassette, is automatically threaded along an external transport path past a web utilization station, by means of a flexible threading band which pushes the web around the path. In a preferred embodiment, magnetic tape, contained in a cassette, is automatically threaded about a tape transport path past a magnetic head assembly by means of a flexible threading band contained in a threading band. The threading band is positioned behind a segment of the magnetic tape and is ejected from its own cassette, (1) to pull the magnetic tape out of the tape cassette, (2) to wrap the tape around a rotary head scanner of a magnetic tape recording/reproducing apparatus, and (3) to configure the tape to the tape transport path. After the tape is threaded, the flexible band is withdrawn into its cassette.

摘要： In a magnetic tape cassette storage and magnetic tape cassette record/reproduce system, disclosed is an accessor which inserts or extracts a cassette from a storage location or a record/reproduce device. The accessor includes a cassette gripper assembly which handles different sizes of cassettes. Lateral motion of the accessor (a) actuates the gripper assembly to grip and ungrip a cassette and (b) effects locking and unlocking of the gripper assembly. A pair of accessors are mounted on an accessor platform so that one accessor can insert a cassette while the other accessor extracts a cassette, either at the same location (record/reproduce device) or at different locations (storage compartments).

摘要： There is disclosed a low power motor and brake assembly for a magnetic tape reel of a magnetic tape recorder/player. The magnetic tape reel is driven by a motor having a rotor fixed to the reel shaft and a stator which is rotatably mounted. A brake assembly includes a brake drum mounted on the reel shaft and a spring loaded brake band engaging the brake drum. One end of the brake band is attached to the stator by a linkage. When the motor is energized, the stator rotates and releases the brake band from the drum by means of rotation of the linkage.

摘要： Methods and apparatus for transporting a heat-generating load through an environment affected by vibrations and pressure variations, employ a capillary structure for advancing that working fluid, when in a liquid state, from a condenser section at a heat-conducting supporting structure spaced from the load to an evaporator section at a heat-conducting load support at the load, for converting the advanced fluid to a vapor state with heat drawn from the load in the evaporator section. There is provided between the supporting structure and the load support a flexible enclosure encompassing around the capillary structure at least part of a space extending from the evaporator section back to the condenser section for returning the working fluid, when in its vapor state, in a heat-transfer cycle to the condenser section for reconversion to its liquid state upon removal of heat through the supporting structure and for reapplication of the working fluid in its liquid state through said capillary structure from the condenser section to the evaporator section for reevaporation thereat with more heat drawn from the load. Resilient means extended between the supporting structure and the load support are provided for effecting vibration damping of the load while removing heat therefrom in the evaporator section with the working fluid converting to its vapor state inside the flexible enclosure and the heat-transfer cycle in the flexible enclosure is protected against pressure variations occurring externally of that flexible enclosure.

摘要： A method of and apparatus for automatically threading a web material from a supply reel to a take-up reel along an external transport path. In a preferred embodiment, the transport path is defined by a plurality of transport elements, arranged to cooperatively communicate with the oxide surface (the information-bearing side) of a magnetic tape, to cooperatively guide the tape along its transport path past a magnetic head station. A vacuum source serves for establishing an air pressure gradient the effect of which is to controllably pull tape, spanning the tape supply and take-up reels, toward the transport elements in the form of an expandable loop which takes the shape of the tape transport path when the loop expands to bring the information-bearing side of the tape into operative engagement with each transport element.
