Title: Magnetic sensing device
IPC: H01F10/08
Filed: 1973-11-09
Abstract: 1450204 Magnetic heads INTER. NATIONAL BUSINESS MACHINES CORP 9 Nov 1973 [29 Dec 1972] 52064/73 Heading G5R [Also in Division H3] A magnetic sensing head comprises a unitary structure of a layer of magneto-resistive material 16 for sensing a magnetic field and an adjacent biasing layer 14 of permantly magnetized material to bias the layer 16 magnetically to a required operating range, layers 14 and 16 being in direct contact with one another. The layers 14 and 16 may be co-planar or laminated, with the direction of magnetization, arrow M h , of bias layer 14 parallel or perpendicular to the easy axis and sense current direction, arrow I, of layer 16. Layer 16 is of permalloy material, e.g. Ni-Fe, Ni-Co or Ni-Fe-Co, and the bias layer 14 may be of ferrite. Layers 14,16, may be evaporated, sputtered or electroplated on a substrate 12 with thicknesses of 200 to 2000 and 50 to 400 Šngstroms respectively. The bias may be established due to exchange or epitaxially coupled layers 14, 16, there being direct atomic contact between the layers. In another form the biasing layer 14 is a composite layer comprising exchange or epitaxially coupled films with a magnetically soft film atomically coupled to a magnetically hard film, e.g. Ni-Fe deposited on a Fe 2 O 3 , a Fe 2 O 3  on Ni-Fe, Co or Co-rich Ni-Co on vanadium or chromium, or binary Co-P. In a further form, the bias layer, or two bias layers with the sensing layer therebetween, is or are formed by preferentially oxiding one or both surfaces of a permalloy sensor strip. Alternatively such surfaces may have localized zones with a raised coercivity produced by chemical reaction with chlorides or sulphates, etching to roughen the surfaces, or by selective deposition of materials which exchange couple to the sensing layer. The combined sensing and bias layers may be surrounded by a magnetic shield (8) in a record head, Fig. 1 (not shown). The head may be used for reading tapes, discs, magnetic ink, or sheets capable of generating and transporting magnetic bubble domains.

Title: Electrical circuitry for monitoring a plurality of current paths
IPC: H02H7/12
Filed: 1974-12-05
Abstract: 1486936 Detecting current imbalance; converting SIEMENS AG 5 Dec 1974 [5 Dec 1973] 52738/74 Headings H2F and H2K A circuit for detecting lack of equality between the currents in a number of lines comprises a plurality of current transformers f1-f4, one for each line, whose secondaries are connected in a closed loop, and a bridge rectifying network b connected to the junctions between the secondaries and providing an output if unbalance exists. The bridge may have a load resistor r coupled to a threshold detector g, or alternatively the rectifiers in the bridge may themselves be threshold diodes. The lines being monitored can be the leads of a plurality of parallel connected rectifiers in a converting or regulating system. If these rectifiers are controllable (as in the A.C. regulator of Fig. 1, including parallel-connected pairs of back-to-back thyristors n1-n8) lack of balance may initiate either interruption of the load or firing pulse circuits (h, s) or reduction in the load current. If the system being monitored conducts in one direction only (Fig. 3, not shown), diodes (e1-e4) are connected in the closed loop and voltage-dependent resistors (r1-r4) shunted across the current transformers secondaries to permit decay of the magnetization currents. The lines being monitored can alternatively be conductors intended to feed equal currents to each of a number of separate loads, e.g. motors. If these loads are three-phase (as in Fig. 2, not shown, where each phase is supplied by pairs of back-to-back rectifiers), three separate balance-detecting systems are provided, each serving the conductors of a particular phase, and the bridge rectifying network (b1-b3) of each system are connected together in series or parallel to provide a combined lack-of-balance warning.

Abstract: 1,174,257. Grinding; gear hobbing; making gears and grinding tools. DEXCO CORP. 19 Dec., 1966 [30 Dec., 1965], No. 56654/66. Headings B3A, B3D and B3K. A tool for finish-forming hardened metal articles such as gears and splines comprises a metal substrate having the form of a worm with a helical thread thereon coated with myriad grits of tungsten carbide. The tool is used in a method of making gears or splines in which, for example, a gear blank 20, Fig. 1, is rough formed by a hobbing cutter 26 and is then hardened in a furnace. Any distortion is removed by the finish-forming tool 34, Fig. 3, which is rotated in engagement with the hardened gear 22. Gear 22 may rotate freely or be driven at a speed co-ordinated with that of the tool.  The tool may be initially formed, using the hob cutter which rough-formed the gear. The surface of the tool is cleaned by shot-blasting and then heated to 200 F. in an oven having a non-oxidizing atmosphere or by a torch. A bonding metal such as nickel-chromiumboron alloy in fused condition is sprayed on the heated surface and bonds with the surface which is then allowed to cool. The surface is thereafter sprayed with a brazing composition and the tungsten-carbide grit is then put on to the composition, only a single layer of grit adhering to the surface. The tool is then heated so that the bonding metal, brazing compound and grit are substantially at the melting point of the bonding metal. During heating, the copper in the brazing compound melts and the grit sinks into the bonding metal and against the metal of the tool which is then allowed to cool.
