Abstract: For record carrier material, the front and the back sides of which are provided with a lacquer layer and the front side of which is coated with an aluminum layer, one of the two lacquer layers is admixed with a material, such as metal azide, which forms a metal radical suitable for reacting with fatty acids, while at least one of the lacquer layers is admixed with a fatty acid or a mixture of fatty acids.

Abstract: PROCESS FOR REDUCING TRACES OF ABRASION OR SCRATCHES ON THE SURFACE OF A RECORD CARRIER The invention concerns a process for reducing or substantially eliminating traces of abrasion or scratches on the surface of a record carrier covered with a thin metallic layer preferably consisting of aluminum. The surface of a paper coated with aluminum, or on which aluminum has been vapor deposited, is covered with a 2 to 1000 nm thick layer of a metallic soap, preferably a saturated metallic soap, an unsaturated metallic soap or a mixture thereof.

Abstract: The disclosure relates to a print buffer, and its addressing, which is used to edit print data for a multiple electrode print head of a metal paper printer wherein the electrodes of the print head are arranged on a slope. The information to be printed is initially stored in the form of a matrix. In accordance with the arrangement of the electrodes in the print head, this information is edited in the print buffer and editing is effected in such a manner that the desired print image is obtained when the print buffer is read column by column. The information stored in a register in, for example, two groups of four bits each, is read in parallel and edited in the buffer. The information of the upper group is stored in buffer 1 and the information of the lower group in buffer 2. Each column address of the buffers comprises four bit positions. The information is written at different points of the four possible bit positions of different column addresses. One buffer line is associated with each electrode of the print head and the information is written into the buffers taking into account the horizontal stagger of the print head electrodes. The buffers are addressed by a suitable logic as a function of the number of electrodes and their mutual spacing. GE 979 044

Abstract: The lacquer layer consists of two layers (2, 6), i. e. one first layer (2) highly filled with coarse-grained pigments (3), and another superimposed low-pigment (7) content second layer (6). The surface thus shows a waviness of high frequency and low amplitude without edges or steps.

Abstract: The invention concerns a process for producing compact, cellulose acetobutyrate based lacquer layers with a high degree of dullness for record carriers coated with a metallic or metalliferous layer, wherein high-molecular polysaccharides, whose polysaccharides have side chains and contain lignin, are admixed to the basic lacquer compound as a filler with a particle size distribution of less than 10.mu.m and a molecular weight of about 106.

Abstract: A print head for an electroerosion printer is provided with a plurality of electrodes, each displaced laterally along the print line by a predetermined distance and using a multiplexing circuit to successively condition each of said electrodes for energization to produce a record mark. The circuit further provides for a single line commonly arranged to carry all energizing signals to all electrodes but effective to initiate energization of the electrodes only upon selection by a decoder. The decoder is operable to condition the individual electrodes in accordance with binary coded signals on a plurality of input lines less in number than the number of electrodes to be controlled. In addition, circuits are provided for energizing a pair of electrodes through a portion of a circuit common to both electrodes by rendering the individual electrodes of the pair responsive only to a particular polarity of electrical signal energization. This technique allows the elimination of a number of control leads originally required and reduces the cost of electrode drivers. Electrode spacing is modified slightly to accommodate the multiplexing control.

Abstract: PRINT HEAD ELECTRODE FOR METAL PAPER PRINTERS Sheathed electrode for metal paper printer in which the core is of material having a higher melting point than the encasing material. This arrangement permits the use of electrodes having smaller crosssection and attainment of finer resolution since only the core is effective during marking.

Abstract: RECORD MARKING APPARATUS Control circuit for printing head of a metal paper printer with electrodes arranged on a slope, said electrodes being staggered in horizontal projection by the D-fold of their electrode width. The matrix-like structurized character consisting of individual image elements is stored in a main storage. This character information is read out column-by-column and written into predetermined locations of a read/ write buffer storage. Such a write phase is followed by a read-out phase of predetermined locations of the storage for the direct addressing of the electrodes of the writing head. Write and read phases are alternating. For determining the address of the storage locations during the write and read phases two counters are used in particular in connection with a multiplier and an adder, as well as a register for storing the D-value.
