Abstract: A single piece electrode comb or device includes two circuit boards having conductor paths and two separate rows of needle-like recording electrodes which are electrically connected to separate paths of the respective circuit board encapsulated in a single plastic resin body with the electrode rows extending to a recording edge formed in a rib along one edge of the body. To form the electrode comb, a device having two substantially similar rectangular cross-sectional shaped halves is assembled in one position to form a winding core on which a wire is wound with a plurality of turns, clamped and joined to the respective circuit boards which are mounted on faces of the two halves, subsequently the wires are separated along a parting plane and the two halves are disassembled with one being rotated 180.degree.

Abstract: The invention relates to facsimile reproduction and particularly to a method for converting a video signal obtained by scanning an original dot by dot and line by line, into a bilevel black/white signal.In the black/white recording of colored originals in which both the background and the information can be white, black, grey or colored, grey/black transitions coming from "white" and grey/white transitions coming from "black" are frequently not evaluated correctly by the dynamic threshold so that information is lost in the copy.In order that these types of transitions are also detected, it is suggested to eliminate the DC component of the video signal and to compare the video signal modified in this way with a second dynamic threshold signal derived from it.

Abstract: Apparatus for electro-optically recording picture information comprising a scanning a picture with a head having multiple electrical optical scanning devices which can be simultaneously moved across the picture and wherein the output of the scanning devices are applied to two storage devices and the scanning device is passed laterally across a picture and then advanced at right angles to the scanning motion and then the scanning head is scanned back across the picture in the opposite direction to the first scan during which time the information from the scanning head is stored in a second plurality of memories. Means for transmitting and recording the information are also provided.

Abstract: The method of electro-optically scanning a picture with a multiple electrical optical scanning head which can be laterally moved across the picture and the outputs of the multiple scanning head are supplied to a first group of shift registers so that individual lines of scanned information will be stored in individual shift registers. After the k lines of information have been scanned and stored in the first group of shift registers the scanning element is shifted to scan additional lines and the output of the multiple scanning device is supplied to a second plurality of shift registers to store information in this group of lines. When information is being written in the second group of shift registers the first group of shift registers are connected to a transmitter to serially transmit line by line the stored information.

Abstract: A method and apparatus for recording graphic or image information by means of punctiform recording spots which are arranged line-by-line according to a recording grid, or multi-lined within a matrix, whereby at the beginning of a contour proceeding obliquely to the recording direction, the first recording spot is displaced in the direction of the contour when its edge does not coincide with the contour and, in order to improve the end edge of such a contour proceeding obliquely to the recording direction, the recording of the last recording spot may be additionally displaced relative to the preceding recording spot by a retarding in time of the recording of said last spot.

Abstract: Apparatus and method for producing image combinations in which the image to be copied are digitally stored and a mask is produced for manually superimposing the images with each other with one of the images and the mask being scanned and wherein the coordinates of the image which is to be transferred into the other image are measured as x and y values and the two images are combined by utilizing the x and y values to form a composite total image.

Abstract: Apparatus and method for improving the picture quality during transmission of facsimile signals which have an image signal having a signal of a particular polarity but has an minimum amplitude to represent a first information state such as white and a maximum amplitude to represent a second information state such as black whereby due to changes of information of the signal inverter pulses are obtained for the formation of a signal of changed polarity such that the change in polarity represents an information state and the zero position represents the second information state.

Abstract: A method and apparatus for electro-optically scanning a picture with a head having multiple electrical optical scanning devices which can be simultaneously moved across the picture and wherein the output of such scanning devices are alternately supplied to storage or memory devices which convert the information from the scanning devices into series arranged information corresponding to each scanning device and wherein during the time that the scanning devices are scanning certain portions of the picture and supplying information to a first set of storage or memory devices, information from a second group of storage or memory devices is being read out to a transmitter for transferring the data to a second location. The invention and method further include a receiver for receiving such information and includes a pair of plurality of storage devices one of which is receiving the incoming information and the other is supplying previously stored information to scanning writing heads.

Abstract: Method and apparatus for electro-optically recording picture information comprising scanning a picture with a head having multiple electrical optical scanning devices which can be simultaneously moved across the picture and wherein the output of such scanning devices are in a time sequential manner applied to storage devices as, for example, shift registers wherein such information can be converted into series information associated with each of the scanning devices in the head and further including a second plurality of storage devices in the form of shift registers in which information can be stored at a time when information is being read out of the first plurality of shift registers.
