Title: Superconductive magnet construction
IPC: H01F6/02
Filed: 1969-05-05
Abstract: 1,254,773. Superconductor magnets. RCA CORPORATION. 5 May, 1969 [6 May, 1968], No. 22771/69. Heading H1P. In a superconductor magnet coil comprising a plurality of helically wound layers of superconductor ribbon, the ribbon is stabilized by a coating of normal metal the cross-sectional area of which is smallest in the layer subjected to the least magnetic field intensity and largest in the layer(s) subjected to the greatest magnetic field intensity. As shown, Fig. 2, the coil is wound on a flanged spool 10 of aluminium or stainless steel provided with insulating layers 16, 18 and 20. Copper shorting bars 22 are placed parallel to the axis of the spool and a layer of stabilized superconductor ribbon is helically wound on to the spool. An interlayer member 32 comprising a sheet 36 of normal metal sandwiched between two insulating films 34 is applied over the first winding layer. Further winding layers separated by interlayer members are then applied and the superconductor ribbons of the various layers are connected in series. The superconductor ribbon comprises a stainless steel core coated with a layer of Nb 3 Sn which is stabilized with a layer of a normal conductor such as silver or copper. The cross-sectional area of the normal metal layer of the ribbon used for each layer is selected in accordance with the magnetic field to which the layer is subjected when the complete coil is energized, being smallest in that layer subjected to the least magnetic field intensity. This enables the size of the coil to be reduced relative to a coil with constant stabilizing layer cross-section without loss of stability. The thickness of the normal metal sheets in the interlayer members may be similarly varied. The cross-sectional area of the superconductor layer of the ribbons may be constant or may be varied in the same manner as the normal metal layers. The conductors may have a circular crosssection, the core may be omitted, and there may be different numbers of turns in the various layers. A group of adjacent layers may be wound using conductors having the same dimensions, and the normal metal sheets in adjacent interlayer members may have the same thickness. The spool need not have flanges and may be of insulating material.

IPC: A44B19/60
Filed: 1954-08-09
Abstract: 781,770. Stapling machines. AERO ZIPP FASTENERS, Ltd. Aug. 4, 1955 [Aug. 9, 1954], No. 23078/54. Class 89(3) A stapling device for securing a staplelike stop member 10, Fig. 5, to a slide fastener or a pair of slide fasteners, comprises a driving plunger 3, Fig. 1, a reciprocatable towards and away from a stapling anvil 2, the plunger having at its lower end two clips 22, Fig. 8, having inwardly bent lower parts 23 between which a stop member 10 is received from a passageway defined between two curved guides 13, 15, Fig. 4. The clips 22 are pivoted to a pin 28 slidable in a slot 34 in the plunger 3 and are biased inwardly at their lower ends 23 by springs 32 to hold the stop member 10 at the lower end of the plunger 3 during downward movement of the plunger, until the prongs 16, 17 of the stop member 10 engage the anvil 2, in which position further downward movement of the clips 22 is prevented by engagement of the pin 28 with shoulders 35 in brackets 31. Thereafter continuing downward movement of the plunger 3 to clinch the prongs 16, 17 forces stop member 10 downwardly past the clip ends 23 causing the clips 22 to yield outwardly to release the stop member. Upon upward movement of the plunger 3 after the clinching operation the clips 22 are moved into their original position to receive another stop member 10 from the passageway between the guides 13, 15. The stop members 10 are fed to the guides 13,15 from a hopper 7 which includes a baffle 14 for ensuring that the stop members pass one at a time to a bridge 12 connecting the guide 13 to the hopper 7. Deflecting surfaces are incorporated in the bridge 12 for tipping any sideways lying stop members on to their backs, while other stop members are rejected from the bridge 12 on meeting the guide 15, and fall through an opening 20 thereof or from the end of the bridge into a container 21. The machine is operated through a lever 5, either by a treadle or electrically. The hopper 7 may be vibrated, either by hand or by lever 5. The clips 22 may be replaced by other suitable means for holding the stop members which may be of different shape from that described

Abstract: 1,153,124. Digital transmission systems; automatic phase control. WESTERN ELECTRIC CO. Inc. 27 May, 1966 [28 May, 1965], No. 23772/66. Headings H3A and H4P. The Specification describes a digital transmission system substantially similar to that described in Specification 1,153,125. The claims relate to the phase control arrangements therein, in which the phase of a clock signal derived from the pilot signals is adjusted by means of a reversible counter controlled by the data and by the preceding starting signals. The received signals pass via the demodulator to an automatic equalizer and thence to a decoding circuit which develops binary signals from the input multilevel signals. During the starting pulses the equalizer sets itself to the required condition and delivers pulses to the reversible counter, the pulses passing to the more significant stages until the derived clock signal is near the correct phase, whereafter they pass to the less significant stages. During reception of data, and provided the bit transition rate is sufficiently high, transition pulses are fed to the least significant stage of the counter. In the event of distortion of the transition distribution curve the pulses are fed to a higher stage. The direction of counting is controlled by a gating arrangement fed by the phasecontrolled clock pulse. The gating arrangement provides clock pulses for the decoding circuit.
