Abstract: 1,226,538. Making transformer cores; bonding; removing finished work. TELCON METALS Ltd. 2 Jan., 1969 [7 Nov., 1967], No. 50596/67. -Headings B3A, B3E and B3W. [Also in Division H1]  In a method of making a laminated magnetic core, a strip of metallic material 2 is wound around a mandrel 3 and a reference groove 4 is cut approximately on the diameter of the coil. The strip is then unwound in steps and at the end of each step it is marked by a marking head 5. The position of the mark relative to the groove 4 is controlled to provide the required joint configuration in the finished core. Preferably, two heads 5<SP>1</SP>, 5<SP>11</SP> are used and the mandrel is rotated 180 degrees at each step. The angle α determines the angle at which the ends of the core halves interleave, the form of the joint being a cross. Three or more marking heads may be used where complex non-linear forms of interleave are required. The strip is then fed through straightening rolls 7, if necessary, and is cut by a guillotine tool 6. Individual strips are fed alternately into two stacks 9a, 9b by a divider 8. They are aligned on a vibrating bed, having a raised bead on one face which engages in the reference grooves. The stacks 9a, 9b are placed on a press 10 and pushed by a ram actuated block 11 into a tube 12 of rectangular cross-section, several pairs of stacks being pressed successively into the tube. The tube with the formed half cores and the blocks 11, which are detachable from the ram, are then heated to stress relieve the half cores. After heat treatment the half cores are pushed through the tube so that the back limbs of the lowermost pair of stacks protrude therefrom. The protruding parts are coated with adhesive by dipping in a tank 14, painting or spraying and when the adhesive has set, they are ejected from the tube, with the next pair similarly protruding. The blocks 11 are removed from the bonded half cores and any burrs removed. The strips are then lightly oiled and assembled into cores, normally by hand. A mating insert 16 and slot 17 may be provided in the core halves, in which case a third marking head will be required for marking the slot and insert.

Abstract: 1,238,161. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 20 Feb., 1969, No. 9129/69. Heading G4A. A data processing system comprises two or more processing units and two or more peripheral (e.g. memory) units, and configuration control means in each unit responsive to a pattern of signals, including a gate bit associated with each unit, from one or other of the processing units to cause the associated unit to assume one of two available configuration states so as to be configured into a subsystem including other units having gate bits of a predetermined value in the pattern, or to be configured out of such a subsystem, the state assumed being determined by the value of the gate bit associated with the unit in which the configuration control means resides. The configuration control means in each unit includes a configuration control register having a gate bit for each other unit (to specify whether the other unit may communicate with the given unit) and a reconfiguration bit for each processing unit (specifying whether that processing unit can alter the register contents, i.e. reconfigure the unit). Any processing unit, under supervisor programme control, can reconfigure the system by sending a "system control out" signal accompanied by first bits equal in number to the number of units in the system and second bits equal in number to the number of processing units in the system. Each unit whose reconfiguration bits permit it to be reconfigured by the sending processing unit, responds to the state 1 or 0 of that one of the first bits relating to it to set the other first bits in true or inverse form respectively into its configuration control register as the gate bits, and sets the second bits into the register as the reconfiguration bits. The register, in each processing unit, can also include a standby bit used in reconfiguring units configured with a master processing unit (in which the bit is 0) to be configured instead with a slave processing unit (in which the bit is 1) on occurrence of an unrecoverable-error interrupt in the master processing unit. Manual facilities for reconfiguration are also provided. Any processing unit can issue (a) a system reset signal which will cause all units to turn on the reconfiguration . bits (to permit reconfiguration by any processing unit) and turn off the gate bits in their configuration control registers and reset the units, or (b) a sub-system reset signal which will reset the units whose gate bits allow them to respond to the issuing processing unit, but the configuration control registers are not altered. Reference has been directed by the Comptroller to Specification 1,108,809.

Abstract: 1,239,421. Balancing slides. MITSUBISHI JUKOGYO K.K. 25 June, 1968, No. 30324/68. Heading B3B. A machine tool comprises a saddle 1, a headstock 2 movable on the saddle, and a counterweight 6 connected to the saddle and headstock by cords, chains or ropes 4, 11, 5. The ropes 4 and 5 comprise first and second connecting means which connect with two first supporting members to support both the saddle and headstock. The rope 11 comprises a third connecting means which connects to a second supporting member which supports the headstock. The connecting means are attached to the counterweight in such positions, and the supporting members are so located that any alteration in the load on the third connecting means 11 caused by movement of the headstock leads to alterations in the loads in the first and second connecting means 4 and 5 so that the saddle and headstock do not tilt about an axis at right angles to the direction of movement of the headstock. The first supporting members comprise levers pivoted on the saddle and which carry rollers that roll along horizontal surfaces of the headstock as it slides horizontally. The second supporting member comprises a lever pivoted on the saddle and which carries a roller that rolls along an inclined surface on the headstock as it slides horizontally. As the headstock moves horizontally the inclined surface causes a variation in the load in the rope 11 which cause compensating variations in the ropes 4 and 5. These compensating variations are effective to compensate for any tilting that may take place as the centre of gravity shifts with the movement of the headstock.

In the method illustrated a number of formers 11 are pressed into grass-seeded base soil 10 and covered with concrete 13 level with the top walls 16. When the concrete 13 has hardened the whole area is rolled to crack and separate the cruciform concrete portion 17. The formers are of fibre or plastics and may be transparent. Natural disintegration of the top walls 16 is speeded up - e.g. by puncturing or dissolving, or by mowing the grown grass. In modifications in which ths base soil 10 is not seeded the interiors of the peaks 12 are filled after removal of the top walls 16 - e.g. with a mixture of soil and seed. In alternative methods, Figs. 3, 4 (not shown), the formers are pressed into a base of unset concrete to define spaces between peaks which may be subsequently filled with seeded soil or with different-coloured concrete. Multi-coloured effects may be obtained by dyeing the undersides of the top walls of the formers.
