Abstract: In a rack-mounted computer system a server unit drawer structure is mounted between spaced pairs of front and rear corner support channel portions of the server cabinet using a pair of specially designed slide support brackets, each positioned on a different side of the drawer structure and extending completely between its associated pair of front and rear corner support channels. Front ends of the brackets have vertically spaced alignment tabs that are complementarily received in openings in side flange portions of the front corner channels and serve to precisely align the front bracket ends, and thus the front end wall of the drawer structure, with the cabinet framework in both horizontal directions. The front and rear ends of the brackets are secured to their associated support channels with threaded fasteners.

Abstract: A network for separating an article-detect signal into a number of parts corresponding to the number of articles randomly disposed in next-abutting relationship is characterized by a circuit arrangement adapted to sample and hold a predetermined percentage of the peak magnitude of a characteristic signal representative of each article, a comparator for comparing the instantaneous value of the characteristic signal with the predetermined peak and for generating an enabling signal when the instantaneous characteristic signal falls below the predetermined percentage, and a timer responsive to the enabling signal to interrupt the article-detect signal for a predetermined time interval after a predetermined time delay.
