Patent GB-962509-A (GB)
Title: Reading-device for an information bearer
Inventor: DALEN CHRISTIAAN JOHANNES VAN
IPC: G06V30/224
Filed: 1962-10-26
Abstract: 962,509. Automatic character reading. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEUR - GENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Oct. 26, 1962 [Nov. 3, 1961], No. 40566/62. Heading G4R. In a character recognition apparatus of the kind in which an image of the characters is passed over a co-ordinate array of photo-cells to produce representative signals, the coding being chosen so that the signals for each character correspond to that character in spite of cyclic row re-arrangement, an optical system is provided to project either a repeated series of images, Fig. 5, or a part of such a series on to the photo-cells so that irrespective of the vertical register of the character, one of the images will produce a set of signals from the photo-cells. The characters are formed with vertical lines in three columns A, B, C, Fig. 1, there being three significant positions in each column, giving nine bits a - j. The characters are shaped (Fig. 4) so that the bit pattern for each character can be cyclically re-arranged vertically without corresponding to the pattern for any other character. The cyclic arrangement depends upon what part of the repeated pattern falls on the photocells, Fig. 2, which in turn depends on the vertical registration of the character. The photo-cell signals are amplified and applied to triggers which have "1" and "O" outputs which are gated together in pairs to respond to vertical line portions of the character. The instant when the character is properly registered in the horizontal direction is found by connecting the "1" outputs of all the triggers of the outside columns to Or gates as shown for column A in Fig. 10A. The outputs of these are applied to an And gate. When line portions are detected in both outside columns and the And gate operates a timing circuit which gates the "1" and "O" signals into corresponding triggers AA-AJ and AA<SP>1</SP> -AJ.<SP>1</SP> The triggers of each column are connected as shift registers and eight clock pulses from the timing circuit step the patterns through the stages. There are nine photo-cells in each column but only three of these are to be used. Connections from the corresponding three in each column are taken to multiple input And gates, one for each character. As the patterns are shifted through the registers, the appropriate gate will respond when the pattern reaches the matching position. The optical system may comprise two half-mirrors Sh1, Sh2 and a full mirror S3 projecting three images simultaneously on to the photo-cell array as shown. In another form the mirrors are smaller so that only one or two receive light from the character at any instant. The projected image corresponds to a section of the repeated image of Fig. 5 having a length equal to the height of a character and it is positioned over the array of photo-cells. An error circuit responds if there is no recognition output.

Title: Numerical control of a machine tool
IPC: G05B19/416
Filed: 1971-09-03
Abstract: 1348325 Numerical control of machine tools SAAB-SCANIA A B 3 Sept 1971 [4 Sept 1970] 41202/71 Heading G3N In a program controlled machine tool receiving a pulse train of frequency fv corresponding to a desired tool speed, and having a function generator 3 which is programmed to distribute its input pulses into trains of frequencies fx, fy, fz whose relative frequencies define the tool direction and wherein the tool moves in increments along a programmed curve, a vector adding computer unit 4 computes a correction pulse train, of frequency is thus dependent upon the direction of tool incremental motion, and which via OR gate 2 is added to fv, the correction ensuring tool movement at the desired rate, independent of tool direction. Alternatively, Fig. 5 (not shown), computer (13) computes the factor a = (fx + fy + fz)/#fx<SP>2</SP> + fy<SP>2</SP> + fz<SP>2</SP>, with which the pulse train fv is multiplied, the result passing to function generator (3). Vector adding computer unit 4, Fig. 2, (not shown). Counter (5) counts all pulses, and, every sixth pulse, provides a triggering pulse to control unit (10). Counters (6) and (7) count the number of pulses in each total of six, which correspond to y, z components of motion, and decoder (9) and adder (12) calculate a quantity four times the correction, nk; corresponding to the train fk; which is added into accumulator register (11). Each triggering pulse to control unit (10) causes, in sequence, counts of four to be subtracted from accumulator register (11) until its count is less than four, the control unit also causing pulses, constituting the correction fk, to be emitted, one for each subtraction. The signal (fv), applied to unit (10) ensures that the correction pulses (fk) interleave with the pulses fv for addition by the OR gate 2. Computer (13), Fig. 5, (not shown), see Fig. 6, (not shown). Every sixth pulse control unit (15) emits a control pulse to register (16), one of whose outputs is correspondingly energized, to condition unit (14), Fig. 5, (not shown), to give one pulse out, for every 32nd, resp 27, 24, 23, 20, 18th in, in dependence on the counts ny, nz, and such output thus controls the output pulse rate of unit (14) receiving as input, a train of frequency 32fv.

Title: Improvements in or relating to printers
IPC: B41J1/20
Filed: 1970-09-01
Abstract: 1287558 Line printer NORTEC COMPUTER DEVISES Inc 1 Sept 1970 [14 Nov 1969] 41740/70 Heading G4H [Also in Division B6] In an impact line printer the characters 302 (Fig. 3a) are carried on a band 300 which also carries marks 304 which may be counter to identify the characters. There are 132 print positions each with its own hammer 100 (Fig. 4). The hammers are biased towards the print position by springs 130 and retained in a cocked position by magnets 110. The hammers are released by activating coils 120 to oppose the magnetic field. When the coil is activated the hammer swings forward and forces the paper against an inked tape and the character. The hammers are divided into five sets of twentyseven each, each set being activated in turn. Data to be printed is fed into recirculating shift register 400 (Fig. 5). The character code at each printer position in turn is registered in counter 610. The marks on the counter band are picked up by sensor 800 and fed to the counter 610. Shift register 400 is advanced five stages at a time so that every fifth character is compared. At the same time counter 610 is advanced by clock 1010. Thus the characters on the type band corresponding to a given print position and the character required for printing are compared by comparator 500. The result being stored on shift register 750. When all the comparisons for a given set have been made, the contents of the shift register are used to activate the hammer release coils for which agreement was obtained. The process is then repeated for the remaining four sets of the print positions. To complete a line of type, the whole process has to be performed sixty-four times so that in a complete cycle every one of the sixty-four characters has at some time been adjacent to every print position.

An air-conditioning system includes an inlet duct 41 and two outlet ducts 42 and 43, the ducts containing heat exchangers 48, 51 and 52 fed with water from the supply lines 30, 31 of a three-pipe system as described in Specification 826,072 in which the heat source and sink are the condenser and evaporator of a refrigeration system. The system shown in Fig. 2 functions under normal conditions as a dual duct system, conditioned air passing to mixing boxes 45 connected to an area to be conditioned, the proportions of air admitted from the ducts 42 and 43 being controlled by dampers 57 and 58. The heat exchanger 48 comprises two coils 49 and 50 connected in series to the return water line and through the coil 51 to the supply lines, the junction of the coils 49 and 50 also being connected to the outlet from coil 52. Valves 53 and 54 control the admission of water to the coils 51 and 52. In normal operation, chilled water is supplied via valve 53 to coils 51, 50 and 49. Oil 49 has a close fin spacing and cools incoming air to or close to its dew point, and coils 50 and 51 have progressively wider fin spacing so that in subsequently dehumidifying the air the fins do not become clogged with water. The flow rate of chilled water through coil 51 is controlled by the valve 53 in response to a thermostat bulb T 1  to maintain the colder air at a desired dew point. A second thermostat having a bulb T 2  controls the valve 53 and overrides the first thermostat to give a required air temperature in the duct 42. The flow of hot or cold fluid through valve 54 to coil 52 is controlled by a thermostat having a bulb T 3  to give a required air temperature in the duct 43. Relays 64 and 65 act in response to thermostat bulbs T 4  and T 5  to operate the air flow control dampers 57 and 58, and may also, under extreme conditions, reset the thermostats T 2  and T 3  to supply cooled or heated air to both ducts 42 and 43. In another embodiment, Fig. 3 (not shown), the exchange 48 is connected separately to the supply pipes of the three-pipe system and both coils 51 and 52 feed to the junction of the component coils 49 and 50. In this case the air inlet receives only fresh air and the water supply to the exchange 48 is under control of the thermostat T 1  and a further thermostat having a bulb located beteewn the component coils 49 and 50. In a further embodiment, Fig. 4 (not shown), four outlet ducts are provided leading to individual areas without any mixing between ducts.
