Patent FR-2506577-A1 (FR)
IPC: A45C1/06
Filed: 1982-05-28
Abstract: The holder has at least three panels (12, 14, 16) which are folded together to form a panel stack and which are held together by straps (54 to 64). The straps (54 to 64) are arranged in such a way that the panels can be opened out about each of the longitudinal sides of the panel stack. The straps (54, 56, 62, 64) run crosswise over some of the panels, while other straps (58, 60) run parallel over the respective panels. At the same time, the straps (54 to 64) form an articulated connection between the panels (12, 14, 16) when the panels are opened out both about the one and about the opposite longitudinal side of the panel stack. Furthermore, the straps serve for transferring sheets or material from an unsecured position above the straps into a secured position below the straps and for retaining the material on the panels in at least four divided areas, each of which can accommodate a relatively large number of sheets. When the holder is inverted, an initially loosely inserted sheet is moved without substantial deformation below the straps which then lead away over the respective panel.

Abstract: The invention relates to a method and device for inverting a television video signal. The method of inverting the signal consists in preserving the signal, during the line-blanking period, with the original modulation and in inverting the useful line signal with respect to an axis passing mid-way between the white level and black level of the video signal. The device consists in setting a first electrode of a capacitor C1 at the white level potential, amplified + g by a differential amplifier 1, by way of a black-alignment circuit 2 and of a sample-and-hold circuit 3; the other electrode is brought to the black level potential amplified - g by the differential amplifier 1. The output is taken, by a multiplexer P2, P3, 4 at the input A of the sample-and-hold circuit or on the first electrode of the capacitor C1. The invention applies in particular to the scrambling of television broadcasts.
