Abstract: A dual curtain closure system for covering a portal wherein each curtain has a length greater than the length of the lateral margins of the portal, a first end fixedly attached across the portal at an upper end thereof, and a second end folded back on itself to define an upwardly opening pocket. An elongated rod is supported within each pocket. A first spindle winds and unwinds the first curtain and a second spindle winds and unwinds the second curtain. A drive motor is operable to simultaneously rotate the first and second spindles such that the upwardly opening pockets of the curtains are concomitantly raised or lowered. A predetermined distance between the rods is maintained as the pockets are raised or lowered, which facilitates sealing of the curtains to the lateral margins of the portal as the curtains are lowered.

Abstract: A multi-panel display board that has a plurality of panels, which include a central panel, two transition panels, two side panels, a header panel and a footer panel. The header panel and the footer panel each flex in an analogous manner with each other between a fold-in orientation and a fold-out orientation and they extend from panel creases that lie between the side panels and the transition panels. The central panel is between the transition panels and separated from them by transition creases. Both the header panel and footer panel have segment creases about which portions of them pivot. A platform extends over the footer panel and simultaneously extends underneath the two transition panels and the central panel.

Abstract: A blank and method of folding same into a multi-panel display board that has a plurality of panels, which include a central panel, two side panels and a header panel, and that has a plurality of beaded portions spaced apart from each other by intervening slit portions. One of the creases lies between the central panel and one of the side panels and another crease lies between the central panel and the remaining one of the side panels. The header panel flexes from a fold-in position to a fold-out position and whose opposite ends from respective creases with the two side panels.

Abstract: A covering device covers a front area of a device for the passage of air. The device for the passage of air fits in an opening in a wall of a casing, in particular a casing of waste heat producing components, of an electronic cupboard, or of a switch cupboard. The covering device also covers a filter mat of the device for the passage of air. The covering device includes a cover covering the filter mat with a number of inclined lamellar elements, each lamellar element has in its upper area a section with a hook-type configuration orientated against the air admission.

Abstract: A multi-panel display project board with a center panel between two side panels and with a header panel movable between a fold-in position and a fold-out position. Each panel has a medium sandwiched between two linerboards. Creases between the panels are formed by slitting linerboard beneath the creases. The side panels may be spread apart to define obtuse angles relative to the central panel and yet retain their position on their own when erected on a flat surface. The header panel has a long segment separated from two shorter segments by segment creases. When the header panel is in the fold-in position after pivoting from a fully folded orientation about panel creases, the shorter segments define respective obtuse angles with the long segment. In the fold-out position after pivoting the header panel about additional creases, the shorter segments define respective reflex angles instead.

Abstract: A multi-panel display project board with a center panel between two side panels and with a header panel movable between a fold-in position and a fold-out position. Each panel has a medium sandwiched between two linerboards. Creases between the panels are formed by slitting linerboard beneath the creases or by forming the creases each as a crushed score. The header panel has a long segment separated from two shorter segments by segment creases. When the header panel is in the fold-in position after pivoting from a fully folded orientation about panel creases, the shorter segments define respective obtuse angles with the long segment. In the fold-out position after pivoting the header panel about additional creases, the shorter segments define respective reflex angles instead. There is no footer or braces.

Abstract: Example roll-up doors are disclosed. An example roll-up door includes a track system and a curtain. The curtain blocks a doorway when a leading edge is at a closed position and unblocks the doorway when the leading edge is at an open position. The roll-up door further includes a track roller to vertically travel along a track system. The track roller is to be rotatable relative to the track system. The roll-up door also includes a windbar to be coupled to the track roller. The windbar is closer to the lintel when the leading edge of the curtain is at the open position than when the leading edge is at the closed position. The windbar is to be vertically movable with the track roller and to be rotatable relative to the track roller and rotatable relative to the track system.

Abstract: A method and apparatus that controls access to a secured area using an automated gate controlled secured environment is disclosed. The method may include receiving an indication that an individual attempting to pass through a clearance area has not been authorized to pass through the clearance area, automatically moving one or more gates to create a channel for the non-authorized individual to be directed to a manual screening area, determining if the non-authorized individual has passed one or more sensor; wherein if the non-authorized individual has been determined to have passed the one or more sensor, then moving a gate located behind the non-authorized individual to enable other authorized individuals to pass through the clearance area while maintaining the channel created to the manual screening area, and preventing the non-authorized individual from gaining access to the automated gate controlled secured environment once the non-authorized individual reaches the manual screening area.

Abstract: A barrier assembly for protecting an edge of a loading platform includes: a gate reciprocating between a barrier position approximate an edge of a loading platform and an open position away from the edge of the loading platform, and a toe barrier mounted approximate the edge of the loading platform and operatively coupled to the primary gate to reciprocate between a barrier position and an open position. The toe barrier provides a vertical barrier along a floor of the loading platform approximate the edge of the loading platform in its barrier position, and is operative to reciprocate to its barrier position when the primary gate is in its barrier position and to reciprocate to its open position when the primary gate is in its open position.

Abstract: A data storage system includes redundant write caches, a disk controller and an array of disks. One of the redundant write caches is a primary write cache of RAM or NVRAM, and another is a backup write cache having a hybrid memory structure of a relatively small amount of NVRAM in combination with a cache-disk space mapped to disk. The cache-disk space may be located on a single disk within the disk array, or distributed over a number of the plurality of disks in the array. In one embodiment, the array of disks can may be configured as a RAID architecture. The data storage system of the present invention preferably employs a conventional, fast-write-fast-read primary write cache and a non-volatile, hybrid memory backup write cache. The redundant write caches are asymmetric since the primary write cache and the backup write cache have different sizes and structures.
