Abstract: A backpack either conventional or of the rolling type having an integrated flexible filing system for storing books, folders, files, papers, and other paraphernalia. The flexible filing system is comprised of a plurality of semi-rigid dividers securely attached to a back wall or panel in the main compartment of the backpack. The dividers are attached to a flexible side wall to allow the system to expand or collapse as needed. Optional features include graduated dividers that are progressively shorter from rear to back to facilitate access to the compartments. An additional optional feature is to make the top edges of the dividers at an oblique angle to facilitate viewing of materials sorted or stored in the compartments formed by the expandable file system. The expandable file systems can also be permanently attached to the back panel of a backpack or could be removable by using a hook and loop fastener.

Abstract: An apparatus for loading wafers into horizontal quartz tube, the apparatus includes a base plate, holding plate, trolley main body and two supporting bases. The base plate has a plurality of stages, which is lifted by a loading rod and fixed atop thereon, for placing wafers. The holding plate has a plurality of fixing screws and altitude adjusting screws for supporting the base plate and changing an altitude of the base plate to match an altitude of wafer boat. The trolley main body, which supports the holding plate by supporting pillars, provides with a plurality of position holes for carrying the holding plate and moving the base plte. The two supporting bases are connected by a solid plate, whose both ends are respectively attached at hollows formed at the middle of each of the two supporting bases. The two supporting bases are provided with a pair of slide bearings on either side of the solid plate.

Abstract: The present invention relates to the use of a group of propargylamines of the general formula (I) ##STR1## wherein R.sup.1 is hydrogen or CH.sub.3 and R.sup.2 is (CH.sub.2).sub.n CH.sub.3 and n is an integer from 0 to 16, and salts thereof, as cellular rescue agents in the treatment and prevention of diseases in which cell death occurs by apoptosis. Some of the compounds of formula I are novel. The invention is also directed to the use of these compounds in the treatment of these diseases, as well as to processes for the preparation of the compounds.
