Title: Improvements in or relating to data processing systems
IPC: G06F13/12
Filed: 1967-02-22
Abstract: 1,144,407. Computer input channel. INTERNATIONAL BUSINESS MACHINES CORP. 22 Feb., 1967 [28 March, 1966], No. 8578/67. Headings G4A and G4C. In a data processing system, a part of an input data word is selectively routed by switching means to an address register to address a storage location for the word, the switching means being capable of connecting any one of a set of lines on which the word appears to any one of the storage positions of the address register. A 51-line real-time input channel to a computer leads to a matrix switch which can permute the connections between these 51 input lines and 51 output lines, 36 of which lead to a data register and 15 to a channel address counter. The contents of the data register can be stored in a core store at an address specified by the channel address counter. The matrix switch contains 51 six-bit control registers, one for each input line, to gate the input line to any one of the output lines. The control registers can be set by programmed control words via the data register. Each 36-bit control word has three 12-bit portions, each portion relating to a respective 17 of the 51 control registers. Six of the 12 bits are placed in a control register selected by 5 of the other bits. The remaining bit is set to 1 unless none of the 17 registers is to respond to the 12 - bit portion. If this remaining bit is 1 and the register-selection bits are all 0, all 17 registers are zeroized (so that they will not gate their respective bits from the input channel to any of the output lines). Experimental values on the input channel can thus be used to address the core store, the contents of the addressed locations being incremented, to keep counts of the various possible experimental values. A high-order carry enables action to be taken after a particular member of particular values have been received by prestoring the complement of the particular number in the appropriate location. Similarly, sums of experimental values can be accumulated. The experimental values may be analogue values digitized and may come from a matrix of photoconductors or &c.

Title: An apparatus for an electrostatic recording of signals
IPC: G03G15/18
Filed: 1959-03-13
Abstract: 900,887. Charging and discharging static electricity. TELEFUNKEN G.m.b.H. March 13, 1959 [March 14, 1958], No. 8774/59. Class 35. [Also in Groups XX, XL (a) and XL (b)] Picture signals are recorded on a moving transparent band 1 which is given a uniform electrostatic charge by a brush 9 and is then selectively discharged in accordance with the signals by passage in contact with a rotating roller 10 having a surface 20 of photo-resistive material which is exposed to light from a luminous screen 11 scanned in a line transverse the roller by an electron beam modulated by the picture signals. The resulting charge pattern on the band is rendered visible by passing the band through a dusting chamber 16, a vibration chamber 17 to remove surplus dust, and finally a varnish or lacquer spraying device 19. As illustrated, the whole process is performed in a sealed chamber which is maintained evacuated by connections 3-8 to pumping apparatus. As an alternative, only the scanning cathode-ray beam is in an evacuated chamber and influences the luminous screen through a Lenard window. The movement of band 1 and roller 10 are synchronized and the two maintain contact over an appreciable distance beyond the recording area so as to take advantage of lag in the conductivity change in the photo-resistive material. Reference is made to the use of cadmium sulphide, antimony sulphide, selenium, zinc oxide, lead oxide and lead sulphide for the photo-resistive material. The luminous screen, which is arranged to be rotated at a slow speed so as continuously to expose a new area to the scanning electron beam, is mounted on a transparent foil carrier, Fig. 2 (not shown), and supported by a clamping ring which may be attached to the rotating shaft by wire spokes. The assembly is rotated in optical contact with a recording band. The cathode-ray beam may be modulated in focus or velocity. The stored signals may be regenerated by the use of a cathode-ray tube flying spot scanner, constructed if desired with a rotating screen similar to member 11, or a vidicon or image-orthicon camera.
