Abstract: According to one aspect, the invention relates to a method of stacking covers for the fabrication of booklets. Each cover includes two cover sheets and an interconnecting spine. Applied to the inner surface of the spine is a binding device that includes a binding agent. The covers are mutually stacked with the inner surface of the spine of one cover lying against the outer surface of the spine of an adjacent cover. According to the invention, a deactivatable separating device is provided between the binding agent and the outer surface of the spine of an adjacent cover, so as to prevent adhesion between the spines of respective covers. According to another aspect of the invention, a cover of this kind is provided with a binding device that includes a binding agent (104) and a separating device (105) disposed on the surface of the binding agent that lies remote from the spine (103), this separating device preferably having a form of woven material affixed to the binding agent (104). The invention also comprises a method of producing a booklet with the use of the inventive cover. According to the inventive method of fabrication, the separating device is deactivated at the same time as the binding agent is activated and a sheet bundle is moved in towards the spine of the cover.

Inventor: LIENHARD HEINZ DIPL-EL-ING
IPC: G01R15/18
Filed: 1978-06-09
Abstract: The measurement transformer consists of a measurement conductor (45), which carries the measurement current (Im), of a premagnetising winding (46) which carries a premagnetising current (Iv), and of a magnetic-field comparator which is subjected to the magnetic field produced by the measurement current (Im) and by the premagnetising current (Iv) and is controlled alternately in both saturation directions. In order to achieve insensitivity to interference signals, a magnetic film (48) is used as the magnetic-field comparator, which magnetic film (48) consists of ferromagnetic, magneto resistive material with contacts (50) for the connection of a current or voltage source. In order to improve clarity, Figure 1 shows the parts of the measurement transformer in an exploded representation. The resistance change which occurs during reversal of the magnetisation of the magnetic film (48) results in voltage or current pulse spikes which mark the zero crossing of the magnetic field. The time shift, caused by the measurement current (Im), of the pulse spikes can be evaluated as a measure of the intensity and direction of the measurement current (Im). <IMAGE>
