Patent GB-1583090-A (GB)
Title: Systems for checking the authenticity of identification papers
IPC: G06T7/00
Filed: 1977-11-03
Abstract: On issuing the document, certain parameters characteristic of the picture (2) affixed thereto are determined, these constituting a code (3) which is stored on the document itself or elsewhere. Whenever the authenticity of the document is to be verified it is necessary to redetermine the said code by constructing a distribution function of the values of brightness of the picture, calculating the integral of the said function and, by subdividing the said integrated function along the ordinate axis into X equal parts, obtaining on the abscissa axis (X-1) values representing the characteristic parameters of the picture. A comparison with the previously determined code is performed next. The apparatus for carrying out this process comprises a device (4) able to register the picture, a device (10, 11) for inputting the comparison code, a device (5, 6, 7) for converting the signals provided by the picture-registering device into digital values and a microcomputer (8). The process and the apparatus can be used to determine the authenticity of credit cards. <IMAGE>

Abstract: 1,083,310. Error correction arrangements. WESTERN ELECTRIC CO. Inc. Nov. 11, 1964 [Nov. 15, 1963], No. 45879/64. Heading G4A. In an arrangement for detecting and correcting errors in a received word comprising data bits and check bits, the erroneous received word is stored in a register having data bit positions and check bit positions, the contents of the register being permuted, e.g. by cyclic shift, until an erroneous bit is in a check bit position, the erroneous check bits are then replaced by correctly calculated check bits, and the register is then subject to inverse permutations so that it finally contains the corrected received word. The arrangement is applicable to cyclic codes. Fig. 5 shows the correction procedure for a 7-bit word comprising 4 data bits and 3 check bits, for correcting a single error. The received word is entered in a register 115, Fig. 1. It is assumed that the boxed bit, Fig. 5, is in error. Check bits are calculated at 130 and compared with the received check bits. A difference in two bit positions (row 3 of Fig. 5) is detected and since this is greater than e = 1= the number of correctable bits, the register 115 is shifted to the left, with end-around carry, to provide a fresh word, row 4 of Fig. 5. This checking procedure is continued until the calculated and registered check bits differ in only one position, rows 13, 14 of Fig. 5. The register bits are then replaced by the calculated bits via a gate 155 Fig. 1, and the corrected word in the register 115 shifted back to its original position to provide the required corrected received word. In order to correct errors in longer received words it may be necessary to subject the received words to permutations other than mere cyclic shift, as described in the Specification with reference to Fig. 6 (not shown).

Abstract: 1336985 Bi-stable resistors INTERNATIONAL BUSINESS MACHINES CORP 6 Oct 1972 [30 Dec 1971] 46158/72 Heading H1K A bi-stable resistor is manufactured by forming an amorphous insulating metal oxide layer 14 on a conductive base electrode 12, heating the layer 14 in the presence of a reducing agent to provide an active region therein, providing a counter electrode 30 on the active region and establishing an electric field between the electrodes 12, 30 to electroform the active region. A voltage of only about 2-3 volts is necessary for the last-mentioned step. The metal oxide layer 14 is preferably of Nb 2 O 5 , formed by liquid phase anodization, thermal oxidation or gas plasma anodization of the Nb (optionally on Pt or Au) base electrode 12. The electrode 12, which may alternatively be of Ta, is located on a substrate 10 of Si, sapphire or glass, and if Si is used the substrate may itself contain diodes series-connected to the array of bi-stable resistors in the layer 14 to provide a memory array. The counter electrodes 30 may be of Bi or Sb. Two alternative reduction processes are described. In the first dots of a reducing metal such as Nb, Bi or Sb are provided on the Nb 2 O 5  layer 14 and the assembly is heated in an inert atmosphere (e.g. helium containing a trace of oxygen). The metal dots are entirely consumed during the oxidation/reduction reaction which results in the formation of active bi-stable filaments in the layer 14, preferably only one filament appearing beneath each dot. In the second method a reducing gas such as 1%H 2  in He is used, the locations of the active regions being defined by windows etched through a Si 3 N 4  mask on the Nb 2 O 5  layer 14.

Abstract: 1283905 Ignition systems FIAT SpA 2 Oct 1970 [7 Oct 1969] 46970/70 Heading F1B In an ignition system a capacitor C is cyclically charged from a direct current source via a conversion circuit 1 and discharged into a high voltage coil B by means of a controlled rectifier SCR. The conversion circuit 1 includes a blocked oscillator comprising a transformer Tr with a saturable magnetic core which during each cycle of operation stores a given quantity of magnetic energy which is independent of the supply voltage and transfers this energy on saturation to the capacitor so that the charging voltage is constant and independent of the voltage of the direct current source. The blocked oscillator is adapted to trigger the controlled rectifier, during that part of the cycle when magnetic energy is accumulating in the saturable magnetic core, in order to discharge the energy stored in the capacitor in the previous cycle. The system is controlled by a contact breaker R which may be a mechanical or electronic contact braker.

Abstract: 1,241,838. Feeding webs. POLYGRAPH LEIPZIG-KOMBINAT FUR POLYGRAPHISCHE MASCHINEN UND AUSRUSTUNGEN VEB. 9 Oct., 1968, No. 47771/68. Heading B8R. In a web unwinding apparatus comprising feeding devices 4, 6 conveying the web 2 at substantially the same speeds, and a dancer roller 5 between the devices controlling the braking of the supply roll 1, means are provided for allowing the speed of the part of the web conveyed by the device 4 to vary relative to the speed of the part of the web being conveyed by the device 6 so that if there is a sudden large increase in the tension of the part of the web between the roll 1 and the device 4 above a value determined by the means allowing the speed variation, such variation will occur and the cylinder 5 will rise to decrease the braking effect on the roll 1. As shown in Fig. 2, an adjustable arm 14 carries rolls 15, 16 which can engage the web between a spring-pressed roll 3 and the roller feed device 4. By adjustment of the arm 14 and rollers 15, 16, the length of web engaging the roller 4 and therefore the frictional force between the web and roller 4 can be adjusted. When the web tension between the supply roll 1 and the roller 4 increases suddenly by an amount exceeding the preset frictional force between the web and the roller 4, slipping will occur, the speed of the web around the roller 4 will decrease, and the dancer roll 5 will be raised to reduce the braking of the roll 1. An adjustable air blast may be directed in the gap between the web and the roller 4 whereby the friction force between the web and roller may be further adjusted. In another form (Fig. 1, not shown), the roller 4 is driven through a slipping clutch allowing the speed of the part of the web passing over the roller 4 to decrease if there is a sudden increase in web tension.
