Title: Improvements in or relating to Automatic Digital Data Processing Devices
Inventor: HARTLEY DAVID
IPC: G06F9/24
Filed: 1966-01-27
Abstract: 1,160,311. Micro-programme controlled data processing device. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 27 Jan., 1967 [27 Jan., 1966], No. 3815/66. Heading G4A. In a micro-programme controlled data processing device, three registers and a plurality of two-state switching devices are provided whereby a series of operations is performed repetitively, with or without the interposition of further operations, for assembling and storing programme data consisting of a plurality of messages (each including a plurality of codes) read from a punched paper tape into the main store of the data processing device. The data processing device is similar to that disclosed in Specification 1,105,245. The programmes to be loaded comprise words of 48-bits each punched (Fig. 2, not shown) in 5 tracks, one of which tracks is for administrative purposes only. Each message word is punched as twelve groups of four data bits (administrative bit = 0) followed by a thirteenth group (administrative bit = 1) which comprises the least significant four bits of the sum of the previous twelve groups thus enabling an error check to be made. Each programme comprising a plurality of message words starts with a start of message code S.O.M. and ends with an end of tape code E.O.T. The tape assembly operation is initiated by manual depression of a console key which conditions the computer order register so as to hold certain predetermined information including the address of the relevant micro-programme and the start address in store to which the tape programme is to be fed. In operation, the paper tape assembly micro-programme controls the computer to search for a start of message code. On finding this the first order is assembled in an accumulator, four bits at a time with shifting at each stage, and then written into store at an address which is incremented as each successive order is loaded. The sum bits are checked as each word is assembled. The computer stops after locating the end of tape code. Manual restarting will then cause the micro-programme to be repeated (if further tapes are to be read-in) or the computer to jump to the beginning of the programme just loaded (if the last tape has been read-in). A flow diagram of the micro-programme is illustrated in Fig. 4 (not shown).

Title: Improvements in or relating to fixings for building and/or like boards
IPC: E04B9/24
Filed: 1955-02-09
Abstract: 799,683. Securing building boards. P.I.M. BOARD CO., Ltd., and FORD, C. Jan. 27, 1956 [Feb. 9,)955]; No. 3926/55. Class 20(4) Building boards 7 8, Fig. 2, are secured in position on the flanges 9 of a T-section beam by means of L-shaped cross-section metal strips P placed in correspondingly shaped slots 11 in the web 10 of the beam, each strip P having tongue portions 1, 2 which are bent into such positions that the strips P cannot be withdrawn from the slots 11. As shown, each strip P has the tongues 1, 2 centrally positioned and spaced apart by a distance only slightly greater than the thickness of web 10, so that when each strip P has been inserted in its corresponding slot 11 and the tongues bent up, the latter closely engage the beam. The slots 11 may be formed in groups, each group having slots 11 at differing distances from the flanges 9 to accommodate boards 7, 8 of different thicknesses. In a modification, the slots are inverted and strips as shown in Fig. 3 are used, the edge 12 of each strip engaging the boards. In a further form L-shaped beams are used, the slots being in the vertical limbs of the beams, and the strips may be shorter.

Title: Improvements in or relating to data handling equipment
Inventor: SHARP JOHN JOSHUA
IPC: G06F13/366
Filed: 1959-02-04
Abstract: 904,334. Electrical digital data-processing systems. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Jan. 25, 1960 [Feb. 4, 1959], No. 3941/59. Class 106 (1). In a data-processing system comprising a number of individual data handling units, transfer of data from one unit to another is made over a common highway. The availability of the highway and the units for datatransfer is indicated in associated indicators which are scanned cyclically. A control circuit is set jointly by transfer instructions and the availability of the highway and the relevant data-handling units to initiate transfer, scanning being halted during transfer. An arithmetic unit is given priority. The highway comprises eight bit-channels 8 and a timing pulse channel 9 and characters are transferred in succession in 8-bit code. When a unit 1-3, 4a-4d, is idle its associated indicator 12 signals an associated gate in the transfer control circuit 11. An instruction is set up in the computer 1 and sent over line 15 to an instruction register 22, Fig. 2, in the transfer control circuit 11. The source and destination addresses are decoded at 25 and 26 to feed appropriate AND gates 30 and 39 which are also fed by the " idle " indicators 12 over lines 13. The source gates 30 are scanned by commutator 32 which stops when it finds an open gate, so energizing gate 38, the selected AND gate 39 relating to the destination and gate 41. Gate 41 sets flip-flop 14 to busy the highway to other instructions and sets flip-flop 29 for a predetermined time to permit the AND gates 27 and 44 to send the necessary control signals from the instruction register to the units concerned. Gate 41 also signals the computer 1 over line 17b to start the transfer timing generator 10. One each of flip-flops 45, 46 is set up to condition read-out and read-in gates 6 and 7, Fig. 1, in the source and destination units, respectively. Transfer takes place through the buffers 5. A transfer complete signal is then sent over line 17c to the transfer control device 11. If transfer is incorrect in any of a number of ways an appropriate gate 53 is opened and an alarm line 17a energized. In known manner the computer unit is given priority, and a transfer involving the computer unit may take place without awaiting the completion of transfer between two of the other units. In this case the information is set up in the buffer of the source and transfer is delayed until the computer unit releases the common highway.

Filed: 1976-02-02
Abstract: 1530635 Automatic control ERWIN SICK GmbH OPTIK-ELEKTRONIK 2 Feb 1976 [7 Feb 1975] 03978/76 Heading G3N [Also in Division G 1] In a curve following system having a photoelectric head 11, Fig. 1, which follows a line 13, additional information is presented to the head by code marks on one or both sides of the line. These marks, e.g. 17, lie in zones 14a, 14b on either side of the guide line zone 12, and the head is provided with masks, or preferably with electronic gating, to sense the zones separately. The code masks are longer than the width of the guide line, so that they can be distinguished from guide line crossings as in Fig. 2. For this purpose the head velocity is integrated during the time taken to traverse the mark in the code zone, so as to measure the mark length. One or more masks may be used on either side of the line for each item of information. The masks may be bar codes. The masks may be detachable stickers which can be placed adjacent the guide line and removed as desired. The information in the codes may control the head movement at an intersection of guide lines, in which case the integrator of the parent Specification may be useful, or may control a machining operation.
