Abstract: A lever and latching arrangement having a pair of camming surfaces disposed on one end thereof is attached to one end of a tailstock member of an electronic memory book or central electronic complex book of a computer. This lever arrangement, as rotated about a pivot axis, engages one of the camming surfaces with a portion of the computer frame; the mechanical advantage of the lever system overcomes the large forces required to connect or disconnect the electronic book from the computer connectors. The pivot axis is positioned between the side rail of the book and the computer frame and between the tailstock and the connectors of the book to afford a low profile relative to the tailstock, permitting a more efficient use of available volumetric space within the computer.

Abstract: An apparatus for preventing leakage of electromagnetic radiation from a modular electronic planar substrate surrounded by an enclosure that includes a bottom portion, a top portion, a first side portion having apertures adapted for receiving electronic cables, and a second side portion having electrical connections therein. The apparatus includes a bracket having a first end and a second end, the bracket connected to the first side portion, wherein the bracket includes an interior portion and an outer portion which contiguously form a first bracket wall, a second bracket wall and a third bracket wall, such that the second bracket wall is positioned approximately perpendicular to the first bracket wall and the third bracket wall.
