Title: Improvements in or relating to magnetic core memories
IPC: G11C11/06
Filed: 1966-12-07
Abstract: 1,147,349. Magnetic core data storage apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 7 Dec., 1966 [28 Dec., 1965], No. 54789/66. Heading H3B. In a memory, magnetic cores are arranged in rows with output conductors threading the cores and an interrogate conductor arranged to pass between adjacent rows so that current flows through the conductor in one direction along one side of each row and in the other direction along the other side, the current producing a magnetic field which passes through the cores in the row adjacent to each side of the conductor. In the multi-planar memory shown data is stored by coincident energization of a word line 14, 16 or 18 and a digit line 32. The data is read-out non-destructively by energizing an interrogate conductor 40 common to all the cores of a plane. In the middle of the array the flux set up by the interrogate current passes through adjacent sides of pairs of cores in adjacent rows. Magnetic keepers 42 provide flux return paths at the edges of the array. The interrogate flux reversably deflects the remanent magnetization in each core to induce an output on each line 32. The magnetic cores may have elliptical instead of circular cross-sections and each row may be embedded in non-magnetic material, with the conductors printed on the surfaces and through the cores. The width of the interrogate conductor is preferably equal to or slightly less than the height of the cores. The cores are reset to the binary zero state before data is written-in. If the storage elements are such that an orthogonal field may be used for enabling write-in, a common conductor may be used for this purpose and interrogation.

Abstract: 1,207,029. Welding electrode holders. H. MYKING. 20 Nov., 1968 [21 Nov., 1967], No. 55009/68. Heading H5H. A welding electrode holder comprises a onepiece elongated conductor 13 adapted to abut a supply conductor 23 at one end and an electrode 11 at the other end, the supply conductor 23 being clamped in electrical contact with end 14 of conductor 13 by an adjustable electrical connector 20 and the electrode 11 being clamped between a pin-shaped projection 19 of the conductor 13 and an adjustable electrical connector 31, the conductor 13 and connectors 20, 31 being surrounded by insulation and the projection 19 being reinforced by a ferrule 19b. Connector 20 has a hexagonal outer cross-section and fits in a similarly shaped passage in a spring reinforced rubber hand grip 24. The conductor 13 is connected to supply conductor 23 by inserting conductor 23 into connector 20 which is already in hand grip 24 and then screwing the connector 20 on to a threaded portion 15 of conductor 13 to clamp the supply conductor 23 between the conical end 14 of conductor 13 and sleeve 20. The rubber grip 24 makes a fluid tight seal with supply cable 12 and is a frictional fit on the central section 17 of ion detector 13. The connector 31 is in the form of a cap and is rotatable with a metal capped insulating synthetic resin sleeve 36. A releasable spring catch 44 in sleeve 36 engages a shoulder 44 of connector 31 to retain it on the sleeve. The connector 31 is screwed on to a threaded stem 18 of conductor 13 so that the electrode 11 is clamped in electrical contact with connector 31 and pin 19. Rotation of a further sleeve 35 and hence connector 31 adjusts the position of the connector on the conductor 13, such axial movement being permitted by axial movement of the hand grip 24. The conductor 13 and connectors 20 and 31 are formed of chromium plated brass but preferably the pin 19 and conical end 14 are silver plated.

A ratchet mechanism for driving a rotary switch comprises a toothed ratchet wheel 4, and a one-piece pawl 17 having a drive nose 23 and a stop nose 24, pivoted at 18 to a pawl carrier 13 which rocks on a knife-edge bearing 12, a driving stoke of the pawl carrier causing the drive nose 23 to advance the ratchet wheel until the stop nose 24 engages a leading tooth flank 6 to prevent further rotation of the ratchet wheel. A torsion spring 25 urges the pawl 17 anti-clockwise to hold the drive nose 23 against the ratchet teeth 5. A part 14 of the pawl carrier 13 forms an armature for a solenoid 9 which when energized rocks the carrier clockwise against the pull of a spring 19 for a return stroke of the pawl. At the end of the return stroke a striker 26 on the pawl carrier opens contacts in the solenoid energizing circuit, and the spring 19 rocks the carrier anticlockwise for a driving stroke of the pawl 17. The pawl carrier may be driven non-electromagnetically.

Abstract: 1,177,239. Automatic temperature control systems. BROWN, BOVERI & CO. Ltd. Dec. 18, 1967 [Dec.20, 1966], No.57473/67. Heading G3R. [Also in Division G1] In apparatus for the measurement or control of the temperature of a moving wire at least one radiation detector responds to a difference between the temperature of the wire and the temperature of a housing through which the wire passes, by providing a feedback arranged to bring the temperatures of the housing and the wire to equality. A temperature measuring device measures the temperature of the housing and supplies an electrical indication to a meter to indicate the temperature of the housing and thus of the wire. In one form the housing is brought up to the temperature of the wire enabling the temperature of the wire to be measured while in another form the housing is maintained at a constant temperature and the wire is heated by amplified feedback of a radiation detector output to a heating coil to bring the wire up to the reference temperature. The radiation detectors may be thermopiles, the hot junctions of which receive radiation from the wire while the cold junctions are embedded in the housing or receive radiation from a reference wire enclosed within and in thermal contact with the housing, Bolometer resistances connected in a bridge circuit, or photo e.m.f. cells connected in opposition.
