Abstract: 1,018,914. Wrapping coils of wire. NATIONAL - STANDARD CO. April 23, 1964, No. 16902/64. Headings B8C and B8M. [Also in Division D1]  Wrapping 55 (Fig. 1) for a reel of wire 27 (see Division D1) is attached to annular side plates 41, 42 fixed on the core of the reel, while the plates are braced against axial displacement. In the form shown the wrapper 55 of fibreboard or sheet material is placed round the wound coil, spliced at 56 and its sides are secured to the outer edges of the plates 41, 42 by forming rollers 60, 61, the flanges 50 on the plates being bent back to grip the wrapper (Fig. 5, not shown). Alternatively the flanges of the plates may be U-shaped (Fig. 6, not shown) and a tie 67 applied to hold the wrapper in place. Circular rims on the plates house mandrels 48 (Fig. 2, not shown) on the drive discs 25 of the winding machine, the axles 24 of which are moved axially to hold the reel. The core may be cylindrical, or formed from two frustums of a cone 37, 38 (Fig. 7) which may be separated by engaging a tab 40 with a turning key to remove the section 37 and enable the reel to be unwound from the inside. The flanges of the core and plates may be joined as shown at 43 or 44. In alternative embodiments the spool 54 may be transferred to a separate machine to secure the wrapper 55. The spool may be lowered on to a wrapper carried on an endless conveyer and recompressed at the wrapping station. Alternatively it may be transported in a rigid support. The wrapper may be removed by a rotary cutter. To prevent corrosion, a valve may be provided so that the package may be charged with helium.

Abstract: 816,042. Engine turning-gear. SPENCER MOULTON & CO. Ltd., G. Dec. 22, 1955 [June 15, 1954], No. 17558/54. Class 7(5) [Also in Group XXVI] In engine turning-gear comprising a plurality of shaft mounted, series connected rubber ring units, each unit has a rubber ring 1, Fig. 3, bonded between centrally apertured metal discs 2, 3, and a shaft locating flange 24. The discs 2, 3, Fig. 4, - which shows them in the mould before the rubber is cured and bonded - have 120 degrees spaced tongues 7, 8, 9 and 10, 11, 12 respectively, which after. curing and subsequent subjection of the discs to a relative twist of 15 degrees, are bent to the interdigitated positions shown in Fig. 2. The maximum permissible wind-up of the unit is thus fixed since the maximum travel of any one tongue is determined by the peripheral distance between the cooperating pair of tongues on the other disc. The twist is transmitted from unit to unit through the interengagement of lugs 14, 15, formed on the discs. To prevent reduction of the central aperture 4 of the unit when the rubber is under maximum torsional stress a metal ring to support the inner cylindrical surface of the rubber is either inserted into a locating groove-shown in Fig. 3-in the rubberafter moulding, or is moulded into the rubber without bonding, or bonded on to the rubber. In a modified unit the discs 2, 3, are dished. Specification 748,078 is referred to.

Abstract: 1334603 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 28 May 1971 [6 Oct 1970] 17808/71 Heading H3B Movement into a read-out position of a single wall cylindrical magnetic domain, or bubble domain, 12, Fig. 1, in an orthoferrite or garnet sheet 10, is detected by a change of potential V s  across a magneto-resistive element 16 connected in a constant current circuit. The orthoferrite or garnet sheet 10 is biased by a magnetic field Hz and the constant current is supplied by a source 18. The magneto-resistive element 16 has a length along the direction of domain movement 14 not exceeding the bubble diameter and consists of a thin anisotropic permalloy film having its easy axis parallel to the movement direction 14. In operation the external magnetic field of the bubble domain rotates the magnetic field of the element 16 and so changes its resistance. The domain 12 may be propagated by energization of conductive loops 24, Fig. 4, or by an A.C. magnetic field, Fig. 5B, the propagation circuit in the latter case comprising a zig-zag line of permalloy 28. One section of the permalloy line 28 forms the magneto-resistance element 16, the electrical connections to the constant current source being provided by conductor leads 30 located on the permalloy pattern. The permalloy line and conductive leads may be built up by deposition and selective etching. Alternatively the propagation circuit may comprise spaced I and T bars of permalloy, Fig. 6A (not shown), with a magneto-resistive element positioned adjacent one of the bars. In a modification, Fig. 6C, the magneto-resistive element 16 comprises a section of permalloy in an I and T bar circuit 32, 34, the spine of the propagation circuit being overlaid by conductive leads 36 extending to the element 16. A so-called "angel fish" propagation circuit is shown in Fig. 7A in which a bubble domain 12 is propagated along a line of permalloy wedges 40 and is restrained into that line by parallel permalloy strips 38; one or more of the strips incorporating a magneto-resistive section 12 and the remainder being overlaid by the conductive leads 42.

When the bar f is tilted to the left it engages and moves the halfnut k, and the other half-nut k<1> is moved simultaneously by the levers l, m, shown in the underside view of the nuts in Fig. 4. A pin o' on the nut k engagea one end of the lever m which pivots against the adjacent plate p, and the other end of the lever m engages the end of the lever l which engages between pins o on the nut k and a hole n in the nut k<1>. If the bar f is to be operable in both directions, the levers l, m are duplicated.
