Title: Method and apparatus for printing coloured images
IPC: B41M1/18
Filed: 1971-08-12
Abstract: 1308116 Printing process AGFA-GEVAERT AG 12 Aug 1971 [17 Aug 1970] 37916/71 Heading B6C [Also in Division H4] In the printing of coloured images by using colour component signals derived by point by point scanning an original, laser means modulated by the signals, form intermediate heat images of each component by melting or destroying areas in a layer of fusible material of the particular component colour provided on a supporting strip, each heat image then being transferred on to a substrate sheet in succession and registration. Normal, untreated paper can be used for the substrate. The fusible material has a wax base.  In the arrangement of Figs. 1, 2, green, blue and red impregnated wax layers are respectively carried by strips 23, 24 and 25. A CO 2  gas laser 1 has its beam divided into thirds by mirrors 2, 3 and 4 for individual amplitude modulation by electro-output means 5, 6 and 7 and subsequent line scan deflection by mirror drums 14, 15 and 16 on the respective wax layer strips 23, 24 and 25, the frame scan being given by the substrates movement. The substrate roll of standard paper 32 contacts the heat images on the wax layer strips at the sites of pressure rollers 34, 35 and 36 such that the three colour images are sequentially transferred on to the paper in correct registration, a magnetically actuated cutter 44 cuts the paper into individual pictures. The laser beam may completely remove areas of the wax layer, Fig. 3, such that a negative image is formed which can then be transferred to the substrate 32 by heating the pressure roller 49 (elements 50) to partly melt the remaining wax areas. Electronic processing of the video signals causes the final image to be positive with respect to the original. If the irradiated wax areas are only partly melted, i.e. made sticky, the areas will transfer to the unheated strip by substrate single sticking, Fig. 4 (not shown). The substrate 54 and strip 56 may travel over the same roller, 53, Fig. 5, with the wax layer 55 in contact with the substrate 54 and heated through the strip. The strip 55, Fig. 6, may start out uncoated and be coated with a loose layer of powdered wax material 71 from vibrated hopper 63. The heated wax areas stick to the strip while the remainder falls off at 3. A vibrating roller 67 aids the loosening of the unmelted powder. A more even coat of powder can be provided if corona discharge devices 70, Fig. 7 (not shown), electrostatically charge the strip, the powder being applied to the charged strip when it is moving vertically upwards. A discharge device is provided adjacent the vibrating roller. The strip may be a closed loop 72, Fig. 8, being irradiated as it travels upwards to the transferring station and being replenished with wax 74 in both 73.

Title: Data processing system
IPC: G06F13/10
Filed: 1968-08-15
Abstract: 1,235,927. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 15 Aug., 1968 [27 Sept., 1967], No. 39074/68. Heading G4A. In a data processing system, words can be transferred a word at a time from a main store holding data and control words to an auxiliary store which is addressable by a plurality of address registers and data from which can be processed a byte at a time. Control words from a main store also holding data and instruction words can be read out to a control register to control, inter alia, read-out in turn of operand address words from predetermined locations of an auxiliary (" active ") store to a memory address register for the main store. The word portion of such an address in the address register addresses the main store to obtain an operand which is inserted into a respective predetermined location in the auxiliary store. The byte portion (two bits) of the address in the address register is inserted in a register in a sub-unit accessing and modifier circuit, this latter register having space for two such byte portions (for two operands respectively) and for a four-bit mask to identify which bytes of one of the operand words in main store are to be finally overwritten with the result of the processing. The mask is preset under control of the appropriate one of the byte address portions. Two adders which also function as decoders are used to increment/decrement the byte portions stored in the register and update the mask as processing (which is serial by byte) proceeds and are used to select, in accordance with the byte address portions, the successive bytes to be supplied to the arithmetic and logic unit from operand word(s) read from the auxiliary store. Addressing of the auxiliary store is under control of section and word select registers the former of which can be controlled from the control register mentioned and both of which can be controlled from a main data bus. However initially the control register addresses the auxiliary store directly via logic. The auxiliary store includes a number of general purpose word registers and the contents of one may be transferred to another via the arithmetic and logic unit a byte at a time under control of four control words (one per byte).
