A storage assembly for mounting '0' to 'N' storage devices to a computer or electronic system. The storage assembly has an assembly base that connects to the housing of the system, '1' to 'M' tray members that support '0' to 'N' storage devices with the '1' to 'M' tray members being connected such that they form a stack of tray members and each tray member has a least one storage device attached to it, shock mount assemblies for movably attaching the stack of tray members with the storage devices attached thereto to the base and for protecting the tray members of storage devices from normal shocks and vibrations, and severe shocks in the horizontal, vertical, and angular directions, 97 LDC board that provides regulated power to the storage devices, an interface board for transferring data to, and receiving data from, the storage devices via a cable assembly that connects to the storage devices in a daisy chain fashion, and 9 connector that connects to the interface board and the storage devices that permits connection of the storage devices and interface board to external devices.

A containment system for significantly reducing the emission of high frequency electromagnetic waves from a computer system into the external environment. The containment system includes the combination of two enclosures and a shielding assembly. One of the enclosures is associated with the high frequency components and the other with the low frequency components of the computer system. The shielding assembly is positioned between the two enclosures to prevent high frequency electromagnetic waves from passing from one chamber to the other over the connection between the two chambers.

In a video display terminal having a housing and a cathode ray tube mounted in the housing, there is provided shift restricting means for applying a selected level of force between mounting ears of the tube and the housing in a direction generally perpendicular to the central axis of the tube. In a preferred embodiment, angle brackets are mounted inside the housing between the enlarged end portion of the cathode ray tube and inside corners of the housing, and lateral force is applied between the angle brackets and the enlarged end portion of the tube for rigidifying the housing. The lateral force is applied by wedges mounted in the brackets for sliding against the mounting ears, and screws are coupled to the brackets for forcing the wedges against the mounting ears.

In a shock and vibration isolation system wherein a device having a top, bottom, sides, front and back is mounted on moving isolators between and in spaced relationship to top and bottom members, front operable locking apparatus for releasably holding the device in place against vertical, lateral and longitudinal movement during shipping. A top releasable locking assembly is disposed between the top member and the device and a bottom releasable locking assembly is disposed between the bottom member and the device. Each releasable locking assembly includes a first pivot bar pivotally mounted to the adjacent member and extending perpendicular to and between the sides of the device. An operating arm is attached to one end of the first pivot bar at right angles thereto and disposed so as to pivot in a plane close adjacent and parallel to the side of the device at the end between a first position lying along the adjacent member and a second position angularly disposed with respect to the adjacent member. A threaded bolt is carried by the adjacent member at the front of the device for releasably holding the operating arm in the first position. A first locking assembly is carried by the first pivot bar and includes locking projections having horizontal stabilizing bars for entering into locking relationship with the device to hold it from movement when the operating arm is in the first position and for moving out of locking relationship with the device to allow metal movement thereof when the operating arm is moved to the second position. Finally, a bias spring is operably connected to urge the operating arm towards the second position whereby when the locking apparatus is released following shipment the device will be unlocked for normal movement.

Shock and vibration isolation mounting apparatus for releasably mounting a computer disk drive, or the like. Two pair of mounting assemblies are used for attaching to the drive and to respective ones of opposed surfaces between which the drive is disposed. One of the pair of mounting assemblies is disposed below the drive with the elastomeric members thereof in compression and the other of the pair of mounting assemblies is disposed above the drive with the elastomeric members thereof in tension. Each of the mounting assemblies comprises a first elongated rigid channel member being U-shaped in cross section and comprising a base separating a pair of parallel spaced sides. The first channel member has a transverse member having a bore therethrough at one end perpendicular to both the base and the sides. The first channel member is adapted for attaching to the disk drive. There is a second elongated rigid channel member also being U-shaped in cross section and comprising a base separating a pair of parallel spaced sides. The second channel member has a transverse member having a threaded bore therethrough at one end perpendicular to both the base and the sides. The second channel member is sized to slidably fit within the first channel member. A spring-loaded captive bolt is carried by the transverse member of the first channel member for passing through the bore of the first channel member and threadedly engaging the threaded bore of the second channel member to pull the transverse members towards one another. First and second elastomeric members are carried by the second channel member on the base between the sides at opposite ends thereof. The elastomeric members each include a captive bolt perpendicular to the base thereof for attaching the second channel member to the adjacent surface. The ends of the first and second channel members opposite the transverse members include interactive ends adapted for drawing the ends together and for holding them tightly together as the captive bolt is used to pull the transverse members towards one another comprising the ends of the sides of the first channel member angling at about 45.degree. back towards the base and the ends of the sides of the second channel member including outward facing tabs angling at about 45.degree. back towards the base so as to wedgedly force the bases of the first and second channel members tightly towards one another.
