    摘要: A multi-channel transparent jacket for accommodating strips of microfilm to create a microfiche, the jacket having non-blocking characteristics, thereby minimizing the tendency of one jacket in a stack thereof to stick to an adjacent jacket. The jacket is constituted by front and rear panels formed of flexible polyethylene terephthalate film joined together by a parallel array of ribs to define the channels. The exposed surfaces of the panels have a friction-reducing layer thereon constituted by a multiplicity of discrete silicon dioxide nodules bonded to the film, the nodule shape approximating a surface segment of a sphere. The peaks of the segments form microscopic contact points which are bonded by molecular attraction to an abutting panel when the jacket is juxtaposed against a like jacket in frictional relationship thereto. The nodules have a relatively large average diameter whereby the population density thereof in a unit area of the layer produces multiple contact points resulting in a coefficient of friction whose value imparts non-blocking characteristics to the jacket to a degree permitting tangential displacement thereof with a like jacket sticking thereto.

    摘要: A single-channel microfiche master housing a strip of microfilm containing one or more frames of reduced scale images, the master being manipulatable in one axial direction only by optical readers and other microfiche-handling machines. The master is constituted by a rectangular tab having a pair of keyhole notches at spaced positions in the lower edge thereof and a single channel transparent jacket accommodating the microfilm strip, one end of the jacket being secured to the tab at a position intermediate the notches to form a T-shaped structure. The microfiche master may be stored in a standard pull-out drawer by a raised pair of rails which is bridged by the tab, the rails passing through the notches whereby the jacket is suspended therebelow in the drawer.
