Abstract: A limit stop filter support apparatus for use in controlling fluidic currents and limiting movement of an actuator within a housing, such as in a data storage device. First and second filter retention members extend from a filter support base to confine opposing ends of a filter used to filter fluidic currents within the housing, and a cantilevered limit stop extends from the base to contactingly limit movement of an actuator moveable within the housing. The limit stop preferably comprises a spring member supporting a latch member, the latch member selectively confining the actuator in a parked position. The first and second retention members each preferably include a shroud surface adjacent an outer peripheral edge of a rotatable storage medium to direct the fluidic currents established by rotation of the medium.

Abstract: There is provided a method for preventing deknitting of knitted tubular articles or garments such as gloves, socks, and the like. Accordingly, the edge of the tubular article or garment is provided with a plurality of horizontally knit rows of thread or yarn which are stretchable or elastic, and a vertical stretchable or elastic yarn or thread is knitted over and around 2 to 12 rows of the horizontal knit rows with gradually increasing tension so as to cause the edge to curl or roll over as a result of the vertical knit.

Abstract: A filtering apparatus and associated method for recirculating fluid in a data storage device. The filtering apparatus comprises a fluid flow guiding member and a filter. The fluid flow guiding member comprises a shroud disposable substantially transverse to the disc comprising an arcuate surface in a closely mating relationship with the disc edge. The fluid flow guiding member further comprises a recessed surface disposable radially outwardly from the disc and cooperatively with the shroud defining a fluid passageway. First edges in the shroud define an inlet to the passageway, and second edges in the shroud define an outlet from the passageway. The filtering apparatus further comprises a filter that is supportable by the fluid flow guiding member within the passageway. The filter provides a curved member against which the fluid flow first impingingly engages upon entering the passageway, thereby being guided by the curved filter toward the outlet.

Abstract: A disc drive includes a base, at least one disc rotatably attached to the base, and an actuator assembly rotatably attached to base and supporting a slider and a transducer at a distal end thereof. The slider and transducer are positioned to be in transducing relation with respect to the disc. An air dam is positioned over the disc and near an arc through which the slider and transducer are rotated. The air dam is positioned so as to produce an area of high pressure substantially about an area including a portion of the arc through which the slider and transducer are rotated. Surfaces are aligned with and extend in a coplanar relationship with the disc to transfer an outwardly directed airflow away from the disc without impinging turbulent flow on or at the disc edge.

Abstract: A method for producing a multi layer protective textile fabric having a base fabric layer with pre-selected areas fibers of a heavier denier or different material inserted pursuant to a computer program and the articles produced thereby. There is also provided a glove prepared by the method comprising different denier fibers and kind of fibers at pre-selected locations having a base unilayer and at least one other layer.

Abstract: The present invention relates to a unilayer flexible performance fabric which may be fabricated into apparel and articles having high performance fibers, such as high tensile modulus fibers positioned within a base fabric in at least one preselected location only where required to import performance characteristics which are equal to or exceed the specifications for the garment. For example, if cut resistance is a requirement, performance fibers which provide such protection from this hazard would be used. Likewise, if abrasion resistance is intended for an apparel such as coveralls, only the knees and elbows would require the performance fiber. Thus, reducing the amount of expensive fibers normally used. The invented fabric is manufacturede in a method in which the placement of the fabric in preselected locations is computer controlled.

Abstract: An apparatus is described which reduces flow-induced disturbances of the head. A disc drive assembly is provided which includes a basedeck and top cover. A spindle motor mounted to the basedeck which rotates around a central axis; at least one magnetic storage disc mounted to the spindle motor for rotation around the central axis and an actuator arm assembly. The actuator arm assembly includes an actuator arm rotatably attached to a pivot axis and a suspension arm attached to a distal end of the actuator arm. A magnetic transducing head is attached to the suspension. The head is used to read and write data to the magnetic storage disc. Finally, a leading surface portion of the actuator arm utilizes several turbulence-reducing portions laterally recessed so as to guide an airflow to reduce a flow-induced disturbance acting on the transducing head.

Abstract: An apparatus is disclosed for reducing disc deflection in response to the application of a non-operational mechanical shock to a disc drive. The disc drive comprises discs rotatable about a disc axis and each having an outer diameter. A circumferentially extending snubber is provided proximate a substantial portion of the outer diameter of each of the discs. The snubber includes a shroud portion immediately proximate the outer diameter of each disc and snubber arms which extend from the shroud portion in a direction toward the disc axis. The snubber limits deflection of the outer diameter of each disc in response to the application of a nonoperational mechanical shock to the disc drive.

Abstract: An apparatus and associated method are described which change the mechanical response characteristics of an actuator arm in a disc drive such that damage to the disc drive resulting from mechanical shock is minimized. An actuator arm is provided which has a groove that extends along a side portion of the actuator arm. A side rail is attached to the side portion of the actuator arm, and is preferably T-shaped so that the side rail mates with the groove. The side rail can be constructed of a stiffening material and/or a damping material as desired to change the mechanical response characteristics of the actuator arm to reduce contact between the actuator arm and the disc surface which results from mechanical shock to the disc drive assembly. In the method of use, a groove is machined into a side portion of an actuator arm and then an actuator arm side rail is inserted into the groove.
