Abstract: 975,979. Disc record data storage apparatus. IBM WORLD TRADE LABORATORIES (GREAT BRITAIN) Ltd. Jan. 10, 1963 [May 22, 1962], No. 19591/62. Heading G5R. Arcuate tracks 64 Fig. 3 on a magnetic disc 12 are scanned by rotating the disc and a head 60 about axes 16, 44 respectively the head being maintained in constant orientation with its track on the axis 62 by gears 52, 54, 56 in the inverse direction to the relative rotation of transducer and disc along the track. The head is only operational for 120 degrees of each successive track circuit to avoid overlapping, and improved track packing-density may be achieved near the centre of the disc, Fig. 4 by varying the start of the operational sector. In an alternative embodiment, Fig. 5, the head is aligned, not by rotation about the axis 62 (Fig. 1) but by a parallel-linkage movement. The precession of the tracks by incremental rotation of a gear coupled to a differential 26, or by a stepping motor included between 24 and 38, is claimed in Specification 975,978. Multiple head-driving arrangements may be used. A single head may be precessed by making the drive ratios for head and disc slightly different from unity.

Abstract: 975,978. Disc record data storage apparatus. IBM WORLD TRADE LABORATORIES (GREAT BRITAIN) Ltd. Jan. 10, 1963 [May 22, 1962], No. 19590/62. Heading G5R The description of Figs. 1-5 is the same as in Specification 975, 979, but the claims are directed to the means for incrementally processing successive tracks. The description extends to multi-head embodiments providing continuous recording:- Fig. 6 requires slip-rings for the heads, but only one drive means for the heads; Figs. 7 and 8 require three drive means but no slip rings since the partial tracks do not overlap. Fig. 9 is equivalent to the single-head embodiment in Fig. 5 (not shown, but see Specification 975,979). Stacked assemblies of discs with relevant heads and common drive means may be used, particularly where the information on the discs is related in decade manner. The heads are preferably of the type supported over the discs by Bernonilli effect.

Abstract: 969,976. Wiring apparatus for an array of ferrite cores. IBM WORLD TRADE LABORATORIES (GREAT BRITAIN) Ltd. Jan. 7, 1963 [April 4, 1962], No. 12895/62. Heading B3E. [Also in Division H3] Wiring apparatus for a rectangular array of ferrite cores comprises a carriage 11 secured to arms 22 of a base member 24, a cylindrical sleeve 14 rotatably mounted by bearings 16 in the carriage, and a wire laying guide comprising a tubular member 10 having a curved end 12, the tubular member being secured to the rotatable sleeve. Wire from a reel (not shown) is threaded over a pulley 29 mounted on a carriage bracket 27 and is passed through the tubular member, the wire being laid by moving the apparatus in straight lines parallel to the rows and columns of cores in the array. The rotatable sleeve and tubular member 10 enables the curved end 12, which may be flared, to align itself to the direction the wire is being laid. To enable projections to be crossed by the wire, e.g. where a large number of wires have already been laid, the arms 25 supporting the base member are made resilient.

Abstract: 906,214. Recording-apparatus. I.B.M. WORLD TRADE LABORATORIES (GREAT BRITAIN) Ltd. Dec. 22, 1960, No. 44021/60. Class 106 (4). Recording-apparatus has mechanism for printing on a record sheet the value of an input variable received in digital form and for printing a symbol representing the source of the variable at a position on the sheet determined by the value of the variable, including switches SW1 to 4, Fig. 2, for applying the digital value to type solenoids 51 to 60 and to a store M1, M2 which is later scanned to control the printing of a symbol in appropriate position. As shown the apparatus has eight channels one for each of eight sources and in each channel there are four ten-position switches SW1 to 4 registering four digits of the value of a variable. The printing-mechanism is a typewriter with solenoid-operated keys for the digits 0 to 9, the decimal point, carriage return, tabulation, space bar and eight symbols. The carriage carries a wiper for bridging a common contact with 164 commutator contacts in succession. With the carriage at the right-hand end and a start switch closed a pulse passes over commutator contact 1 line L1 to solenoid 50 which operates the space bar. In position two a pulse passes over contact 2 and switch SW1 to solenoid 53 which prints the tens digit " 2." In position three the units digit " 0 " registered on switch SW2 is printed. In position four a pulse passes over contact 4 and line L2 to solenoid 22 which prints the decimal point. In positions five to seven the two digits registered on switches SW3, SW4 are printed, followed by a space. This sequence is repeated for the other seven channels. The pulses passing through the switches SW1, SW2 of each channel are routed through two magnetic core matrices M1, M2 each with eight rows, one for each channel and ten columns, one for each digit 0 to 9. There is a core at each intersection which changes its state only when a pulse appears simultaneously on its row and column. The pulse over commutator contact 2 appeared on the row of the tens matrix M1 corresponding to channel 1 and on the column for digit two and the pulse over contact three appeared on the row of the units matrix M2 for channel 1 and on the column for digit nought. Thus, when the value in channel 1 was printed its first two significant figures were stored and the same thing happens in each channel until commutator contact 63 is reached. Over the remaining contacts 00, 01 ... 100, Fig. 3, the matrices M1, M2 are scanned electronically in ascending order. The matrix M1 is interrogated by half current pulses applied to serial pairs of conductors 100-109 connected to commutator contacts 00, 10, 20 and the resetting of an activated core produces an output pulse on one of the row conductors 111 to 118. The matrix M2 is interrogated by half current pulses applied to row conductors R9 to R16 and column conductors C0 to C9 connected to commutator contacts 01 to 09, in parallel with 11 to 19, 21 to 29 and so on, coincident application re-setting a core and producing an output pulse on one of the rows R1 to R8 to cause energization of a solenoid 61 to 68 to print a symbol representative of the source from which the scanned value has been derived. When a pulse is applied to a column conductor 100-109 of M1 such as 101 which does not contain an activated core signifying a stored value the tabulate key solenoid 49 is energized causing the carriage to move over ten spaces without scanning the matrix M2. If two identical values occur, only one symbol is printed. A bias circuit 77 inhibits printing of the second symbol and prevents any solenoids being energized by random pulses occurring during carriage return. The carriage is returned, after reaching the last contact 100, by energization of solenoid 21. A set of switches SW1 to SW4 without matrices M1, M2 registers the time and provides for the printing thereof at the beginning of each line. A relay inhibits printing for any channel until the value of the associated variable has been registered on its switches SW1 to SW4.

Abstract: 977, 737. Permanent stores. IBM WORLD TRADE LABORATORIES (GREAT BRITAIN) Ltd. April 18, 1963 [April 24,1962], No. 15595/62. Heading G4A. [Also in Divisions H1 and H3] Each magnetic storage core 10 of a permanent store has its drive winding 15 connected to the secondary winding 19 of a respective transformer, the coincident selection conductors X, Y of the store forming transformer primary windings. A core is switched only when both primary windings of the associated transformer are energized simultaneously. Only certain cores in each row are switchable, a single X conductor being provided which extends through the store and threads selected transformers in each row, and a separate Y conductor being provided for each row which threads all the transformers in the row. The basic assembly comprises insulating base members 20, Figs. 3 and 4, carried by semicircular end members 21, the base members supporting U-shaped core portions 13 of the transformers. The X and Y conductors are fitted to the basic assembly, the conductors being laid so as to pass through the aperture of a transformer core or to by-pass the aperture as required by the wiring pattern. When wiring is completed, insulating strip members 16 are fitted over the U-shaped core portions, the strips being printed on one surface with an earthing circuit 17, Fig. 6, and having printed secondary windings 19, Fig. 5, on the opposite surface. Subsequently the transformer cores are completed by fitting I-shaped portions 11 which are attached to portions 13 by clips 8. The toroidal storage wires 10 are supported by polystyrene frames 14 which are mounted on the strip members 16, the drive windings 15 threading the cores being connected to the respective printed secondary windings by terminal tags. The columns of cores are threaded by sense windings 12 which as shown in Fig. 4 alternate in direction through the cores. Ferrite rods or magnetic thin films may be used in place of the toroids. Specifications 969,976 and 977,738 are referred to.
