Patent GB-749649-A (GB)
Title: An improved joint for electric conductors
Inventor: BANKS JOHN
IPC: H02G15/18
Filed: 1953-09-04
Abstract: 749,649. Sleeve couplings. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Sept. 3, 1954 [Sept. 4, 1953], No. 24501/53. Class 38 (1). A joint between two stranded conductors is made by cutting back the outermost layer of wires 2, inserting a ferrule 3 of high conductivity metal (e.g. copper) in the recess thus formed, and surrounding the ferrule 3 by another ferrule 4 of high mechanical strength (e.g. beryllium or cadmium copper). The spaces in the inner and outer ferrules are filled with solder and ferrule 4 is terminated by a tapered layer of solder 5 wired on to conductors 2. The ferrule 4 may alternatively itself have tapered ends. In another embodiment (Fig. 2, not shown), the conductors inside the inner ferrule are cut back to different lengths and opened out, solder being again used to fill the spaces. The ferrules may be tubes split longitudinally either once or twice, or may be tubes with an aperture to permit the entry of solder, or the outer ferrule may be formed of a thin metal sheet bent round the inner ferrule, a gap being left between the ends for the solder.

Title: Improvements relating to variable electrical inductances
IPC: H01F29/10
Filed: 1954-08-23
Abstract: 764,614. Inductors. PATENT MANAGEMENT, Inc. Aug. 23, 1954 [Aug. 27, 1953], No. 24509/54. Class 38 (2). A variable electric inductance, as described and claimed in Specification 725,329, is modified so that the movement of the member providing the unidirectional magneto-motive force is arranged to vary the air gap in such a manner that a scale indicating the values of inductance is relatively evenly-divided over its whole length. A variable inductor unit comprises two inductors each of which consists of two coils 13, 14, each coil surrounding a limb of each of two ring-like core members 10. The lower parts of the members 10 are bridged by a magnetic member 15 whilst the upper parts are bridged by a magnetic member 16 forming a flux generator which may be either a permanent magnet or an electromagnet. The member 16 is movable to vary the air gap between it and the rings 10, the member 16 associated with each inductor being carried by linkages 17, 20, 21 so as to be simultaneously operable by a single control 27 by means of worm gearing 24, 25. The members 16 move in a circular arc, thus the air gap changes according to a square law which corresponds to the change of flux law. Initial adjustment of the air gap is made by means of shims 31 placed between the structure carrying the members 16 and the structure carrying the coils 13, 14. A further flux generator in the form of a permanent magnet 30 adjustably bridges the two rings 10 of each inductor to give initial adjustment of the value of the inductor, adjustment of this member 30 being independent of the adjustment of the magnets 16. Each inductor may, if desired, comprise only one coil and the movable part of the core may be other than the magnet 16. A further adjustment may be made by placing a piece of magnetic material on the magnet 16, thereby shortcircuiting some of the flux emanating therefrom.

Title: Magnetic device
Inventor: SMITH LAWRENCE RAY
IPC: H03K17/82
Filed: 1962-06-28
Abstract: 981,411. Magnetic storage devices. MOTOROLA Inc. June 28, 1962, No. 24910/62. Heading H1T. [Also in Division H3] A magnetic storage, logical or transfer (or negating) device comprises a core member 11 (Fig. 1) (or two separate core members) having major apertures 14, 15 and minor output apertures 17, 19, the latter being linked oppositely by an output winding 24, an input winding 23 linking two other minor apertures 16, 17 (or the major apertures if two separate cores are used). The core is set in the cleared state by a pulse in winding 29 which sets the flux clockwise round each or the major apertures so that it is in the same direction on both sides of the minor apertures (Fig. 2, not shown). A clockwise (" one ") input pulse of sufficient amplitude in winding 23 then reverses the flux round leg 13 and sets the flux round aperture 16 and output aperture 17 anticlockwise and clockwise respectively the flux round the other output aperture 19 being unaffected. An amplitude limited sensing clock pulse in winding 28 then switches the flux round aperture 17 producing a " one " output in winding 24 greater than any opposing (spurious) output which may be produced by the flux round aperture 19. After the core has been cleared an anticlockwise (" zero ") signa in winding 23 stores a clockwise flux round aperture 19 from which an oppositely directed (" zero ") output may be obtained in circuit 24. A nil reading in circuit 24 may be utilized to represent a third element of information. Two separate matched cores may be used instead of a single core (Fig. 10, not shown). The core need not be symmetrical or of rectangular loop material. A shift register may comprise a number of cores 11a, 11b (Fig. 9). After the flux is set clockwise round both major apertures of 11a by a clearing pulse in winding 35, a binary " one " pulse from a previous stage passing through input winding 30 is sufficiently large to set an anticlockwise flux round 16a and a clockwise flux round 17a. An amplitude limited priming clock pulse in winding 34 then reverses the flux round 17a but not round the major flux paths and the current produced in winding 31 is prevented from affecting core 11b because the priming pulse also passes through 16b. A clearing pulse in winding 35 then resets the core to the cleared condition producing a pulse in winding 31 which shifts the binary " one " to core 11b. Repetition of these operations with core 11b then transfers the " one " to the succeeding stage. If the input pulse is in the opposite direction the flux pattern in the lower of the two major flux paths is affected, the information being stored as a flux round aperture 19a and clearing producing a pulse in winding 31 in a direction opposite to that produced by a " one ".
